An evanescent cutaneous reaction occurring when antibody is injected into a local area on the skin and antigen is subsequently injected intravenously along with a dye. The dye makes the rapidly occurring capillary dilatation and increased vascular permeability readily visible by leakage into the reaction site. PCA is a sensitive reaction for detecting very small quantities of antibodies and is also a method for studying the mechanisms of immediate hypersensitivity.

Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.
The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of IgE, cross-linked by antigen, to the mast cell or basophil's Fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects.

It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
Immunosuppression by the administration of increasing doses of antigen. Though the exact mechanism is not clear, the therapy results in an increase in serum levels of allergen-specific IMMUNOGLOBULIN G, suppression of specific IgE, and an increase in suppressor T-cell activity.
Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood.
A chromone complex that acts by inhibiting the release of chemical mediators from sensitized mast cells. It is used in the prophylactic treatment of both allergic and exercise-induced asthma, but does not affect an established asthmatic attack.

Structural determinants of the eosinophil: chemotactic activity of the acidic tetrapeptides of eosinophil chemotactic factor of anaphylaxis. (1/1066)

The acidic tetrapeptides of ECF-A, Ala/Val-Gly-Ser-Glu, exhibit peak in vitro chemotactic activity for human eosinophils at concentrations of 3 X 10(-8) M to 10(-6) M, and rapidly deactivate eosinophils to homologous and other stimuli at concentrations as low as 10(-10) M. The analogue Leu-Gly-Ser-Glu reaches peak activity at 10(-8)M-10(-7)M, while Phe-Gly-Ser-Glu requires 10(-4)M to elicit a peak response. Although inversion of the order of glycine and serine does not alter the eosinophil chemotactic activity of the tetrapeptides, deletion of glycine increases by 10-fold the concentration required for peak chemotactic activity, indicating the critical nature of the spacing between NH2- and COOH-terminal residues. The substituent COOH-terminal tripeptide, which is only marginally chemotactic, irreversibly suppresses eosinophil chemotactic responsiveness at a concentration 10,000-fold higher than concentrations necessary for deactivation by the intact tetrapeptide. The high concentration of tripeptide required for this cell directed effect, which is assumed to be analogous to deactivation, is attributed to the absence of the NH2-terminal residue which would facilitate effective interaction with the eosinophil. A substituent NH2-terminal tripeptide and amides of the NH2-terminal amino acids, which are devoid of chemotactic and deactivating activities, reversibly inhibit the tetrapeptide stimulus in a dose-response fashion. The additional finding that the NH2-terminal tripeptide protects the eosinophil from deactivation by the intact tetrapeptide confirms that the competitive interaction is stimulus specific.  (+info)

The cat lung strip as an in vitro preparation of peripheral airways: a comparison of beta-adrenoceptor agonists, autacoids and anaphylactic challenge on the lung strip and trachea. (2/1066)

1 A new in vitro preparation, the isolated lung strip of the cat, is described for investigating the direct effect of drugs on the smooth muscle of the peripheral airways of the lung. The preparation comprises a thin strip of lung parenchyma which can be mounted in a conventional organ bath for isometric tension recording. Its pharmacological responses have been characterized and compared with the isolated tracheal preparation of the cat. 2 The lung strip exhibited an intrinsic tone which was relaxed by catecholamines, aminophylline and flufenamate. It was contracted strongly by histamine, prostaglandin F2alpha, acetylcholine, compound 48/80, potassium depolarizing solution and alternating current field stimulation. In contrast, the cat trachea was unresponsive to histamine and prostaglandin F2alpha and did not exhibit an intrinsic tone. 3 (-)-Isoprenaline and (-)-adrenaline were much more potent in relaxing the lung strip than the trachea. The potency order of relaxation responses to isoprenaline, adrenaline and (+/-)-noradrenaline in the lung strip was isoprenaline greater than adrenaline greater than noradrenaline but in the trachea was isoprenaline greater than noradrenaline greater than or equal to adrenaline. 4 beta2-Adrenoceptor selective agonists salbutamol and terbutaline were more potent in the lung strip than the trachea, suggesting beta2-adrenoceptors predominated in the lung strip. Propranolol was equipotent in inhibiting isoprenaline relexations of the lung strip and trachea, whereas practolol was much less effective in inhibiting lung strip than trachea, further supporting a predominance of beta2-adrenoceptors in lung strip and beta1-adrenoceptors in trachea. 5 Strong Schultz-Dale type contractions were elicited in both lung strips and trachea by Ascaris lumbricoides antigen in actively sensitized cats. The initial phase of the contractile response of the lung strip following challenge was shown to be due to histamine release and was absent in the trachea. The delayed phase of the contraction which took several minutes to develop in both the mepyramine-treated lung strip and trachea was not due to prostaglandins E1, F2alpha or bradykinin, the probable mediator being slow reacting substance of anaphylaxis (SRS-A). 6 It is concluded that the isolated lung strip of the cat is useful as an in vitro model for investigating the effect of drugs on the smooth muscle of the peripheral airways of the lungs.  (+info)

Anaphylactic bronchoconstriction in BP2 mice: interactions between serotonin and acetylcholine. (3/1066)

1. Immunized BP2 mice developed an acute bronchoconstriction in vivo and airway muscle contraction in vitro in response to ovalbumin (OA) and these contractions were dose dependent. 2. Methysergide or atropine inhibited OA-induced bronchoconstriction in vivo and airway muscle contraction in vitro. 3. Neostigmine potentiated the OA-induced bronchoconstriction in vivo and airway muscle contraction in vitro of BP2 mice. This potentiation was markedly reduced by the administration of methysergide or atropine and when the two antagonists were administered together, the responses were completely inhibited. 4. Neostigmine also potentiated the serotonin (5-HT)- and acetylcholine (ACh)-induced bronchoconstriction and this potentiation was significantly reversed by atropine. 5. These results indicate that OA provokes a bronchoconstriction in immunized BP2 mice by stimulating the release of 5-HT, which in turn acts via the cholinergic mediator, ACh.  (+info)

Mediators of anaphylaxis but not activated neutrophils augment cholinergic responses of equine small airways. (4/1066)

Neutrophilic inflammation in small airways (SA) and bronchospasm mediated via muscarinic receptors are features of chronic obstructive pulmonary disease in horses (COPD). Histamine, serotonin, and leukotrienes (LTs) are reported to be involved in the exacerbation of COPD, and currently, histamine has been shown to increase tension response to electrical field simulation (EFS) in equine SA. We tested the effects of these mediators and the effects of activated neutrophils on the cholinergic responses in SA. Histamine, serotonin, and LTD4 had a synergistic effect on EFS responses and only an additive effect on the tension response to exogenous ACh or methacholine. Atropine and TTX entirely eliminated the EFS-induced tension response in the presence of all three inflammatory mediators, indicating that augmentation of the EFS response applies only to the endogenous cholinergic response. Neutrophils isolated from control and COPD-affected horses were activated by zymosan, producing 18.1 +/- 2.3 and 25.0 +/- 2.3 nmol superoxide. 10(6) cells-1. 30 min-1, respectively. However, in contrast to the profound effect of mediators, incubation of SA for over 1 h in a suspension of up to 30 x 10(6) zymosan-treated neutrophils/ml did not significantly affect EFS responses of SA isolated from either control or COPD-affected horses. We conclude that in equine SA 1) the endogenous cholinergic responses are subject to strong facilitation by inflammatory mediators; 2) activated neutrophils do not affect cholinergic responses in SA; and 3) in acute bouts of equine COPD, histamine, LTD4, and serotonin (mediators primarily associated with type I allergic reaction) rather than mediators derived from neutrophils most likely contribute to increased cholinergic airway tone.  (+info)

Effect of bolus epinephrine on systemic hemodynamics in canine anaphylactic shock. (5/1066)

OBJECTIVE: Epinephrine (Epi) is considered to be the drug of choice for anaphylactic shock (AS). However, the benefit of this drug on improving systemic hemodynamics in AS has never been shown. We used a canine ragweed model of AS to determine if an intravenous bolus of Epi hastened the recovery of hemodynamics and modified mediator release (Med) compared with no treatment (NT). METHODS: In one protocol (n = 8), the effects on hemodynamics of two intravenous doses of Epi (0.01 and 0.025 mg/kg) were examined for 3 h postshock in respective studies approximately three weeks apart under pentobarbital anesthesia in the same animal. In five other dogs, left ventricular (LV) mechanics were additionally determined by sonomicrometric techniques to determine changes in contractility as defined by the preload recruitable stroke-work (SW) relationship. RESULTS: Compared with NT values, Epi treatments produced only transient increases in mean arterial pressure (MAP) and cardiac output (CO) post-challenge. By 20 min postshock, CO in the Epi studies were generally lower (p < 0.05) and BP was not different from NT values. With Epi treatment, SW was reduced for a given LV end-diastolic volume compared with the control study. Epi treatments also caused relatively higher plasma thromboxane B2 concentrations postshock. CONCLUSION: Our findings indicate that, when given immediately postshock, bolus-Epi did not hasten recovery and caused impairment in LV mechanics in canine AS.  (+info)

Strain-dependent induction of allergic sensitization caused by peanut allergen DNA immunization in mice. (6/1066)

To investigate the potential application of allergen gene immunization in the modulation of food allergy, C3H/HeSn (C3H) mice received i.m. injections of pAra h2 plasmid DNA encoding one of the major peanut allergens, Ara h2. Three weeks following pDNA immunization, serum Ara h2-specific IgG2a, IgG1, but not IgE, were increased significantly in a dose-dependent manner. IgG1 was 30-fold higher in multiply compared with singly immunized mice. Ara h2 or peanut protein injection of immunized mice induced anaphylactic reactions, which were more severe in multiply immunized mice. Heat-inactivated immune serum induced passive cutaneous anaphylaxis, suggesting that anaphylaxis in C3H mice was mediated by IgG1. IgG1 responses were also induced by intradermal injection of pAra h2, and by i.m. injection of pOMC, the plasmid DNA encoding the major egg allergen protein, ovomucoid. To elucidate whether the pDNA immunization-induced anaphylaxis was a strain-dependent phenomenon, AKR/J and BALB/c mice also received multiple i.m. pAra h2 immunizations. Injection of peanut protein into these strains at weeks 3 or 5 following immunization did not induce reactions. Although IgG2a was increased significantly from week 2 in AKR/J mice and from week 4 in BALB/c mice and remained elevated for at least 6 wk, no IgG1 or IgE was detected. These results indicate that the type of immune responses to pDNA immunization in mice is strain dependent. Consequently, models for studying human allergen gene immunization require careful selection of suitable strains. In addition, this suggests that similar interindividual variation is likely in humans.  (+info)

Evidence of anaphylaxy after alteplase infusion. (8/1066)

BACKGROUND AND PURPOSE: Although alteplase, a recombinant tissue plasminogen activator (tPA), is structurally identical to endogenous tPA and therefore should not induce allergy, single cases of acute hypersensitivity reactions have been reported. Until now, specific antibodies against alteplase were not detected in blood samples obtained in these patients. CASE DESCRIPTION: We report an anaphylactic reaction in a 70-year-old white female who was treated with intravenous alteplase for thrombolysis of acute ischemic stroke 160 minutes after onset of a right-sided hemiparesis. Thirty minutes after infusion of alteplase had been started, the patient suffered acute severe sinus tachycardia and hypotension, followed by cyanosis and loss of consciousness. The alteplase infusion was stopped, and following antiallergic therapy, tachycardia and hypotension resolved within 1 hour. The hemiparesis remained unaltered, but additional harm resulting from the hemodynamic complication was not observed. Serum samples analyzed with a radioimmunoprecipitation assay were negative for total antibodies to alteplase, but in a subsequent ELISA, both samples were positive for IgE antibodies to alteplase. CONCLUSIONS: The detection of specific IgE antibodies reactive with alteplase in this patient could provide the first evidence of an anaphylactic-type reaction to alteplase in man. Because previous exposure to alteplase can be excluded, the results suggest that this patient had preexisting antibodies that were cross-reactive with one or more epitopes of alteplase and therefore precipitated the anaphylactic-type reaction.  (+info)

Definition of anaphylactoid reaction in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is anaphylactoid reaction? Meaning of anaphylactoid reaction as a legal term. What does anaphylactoid reaction mean in law?
Published Online: September 9, 2013. Food-induced anaphylaxis is a potentially life-threatening systemic allergic reaction that often results in emergency department (ED) visits and/or hospitalization. Epinephrine is the first-line treatment for anaphylaxis and its prompt and correct administration can be lifesaving. After an ED visit/hospitalization for anaphylaxis, US national guidelines recommend several actions, including prescription of an epinephrine auto-injector (EAI) and referral to an allergist/immunologist.. In a recent study of healthcare claims in 1,370 US adults, published in The Journal of Allergy and Clinical Immunology: In Practice, Landsman-Blumberg et al examined patient concordance with recommended post-discharge care after an ED visit or hospitalization for food-induced anaphylaxis. While previous studies investigated physician adherence with US national guidelines, the new study evaluated if patients actually fill/refill an EAI prescription and visit a specialist ...

article{1e9e7fa6-4990-4ef4-af96-b18ff9968d5d, abstract = {,p,Anaphylaxis/anaphylactoid reactions have recently been reported after few treatments with factor IX concentrates in patients with haemophilia B at the same time as inhibitors to factor IX were demonstrated. In some of these cases nephrotic syndrome has appeared during immune tolerance induction (ITI) with high doses of factor IX concentrates. Gene deletions seem to be associated with a high risk of developing antibodies to factor IX. This report presents two brothers with deletion of 1 bp in exon f of the factor IX gene. Both showed anaphylactoid reactions and they were desensitized using slow i.v. injections of factor IX. At the time of anaphylaxis, inhibitors of factor IX in a low titre could be demonstrated. The elder brother responded well after a short time on ITI and has no spontaneous bleedings on regular prophylaxis although in a somewhat higher dose than expected. On the other hand, in spite of comparable regimens, the younger ...
Anaphylaxis is classically induced by IgE-dependent FceRI crosslinking that triggers mast cell and basophil mediator, enzyme and cytokine secretion. Anaphylaxis can also be induced in mice, however, by IgG- mediated crosslinking of macrophage and basophil FcgRIII. This alternative pathway may be responsible for some cases of human anaphylaxis, particularly those associated with protein-based drugs, including humanized mAbs. We used mouse passive anaphylaxis models to attempt to identify markers that could distinguish between IgE- and IgG-mediated anaphylaxis. Mice sensitized by i.v. injection of TNP-specific IgE or IgG mAbs were challenged i.v. 24h later with TNP-OVA; changes in cells and serum were then evaluated. Changes 2h post-challenge in both IgE- and IgG-mediated anaphylaxis included: 1) up to 90% decreases in percentages of basophils and monocytes in blood; 2) doubling of the percentage of neutrophils in blood; and 3) ~25% increases in the ability of neutrophils to generate reactive ...
Prevalence of food-induced anaphylaxis increases progressively and occurs in an unpredictable manner, seriously affecting the quality of life of patients. Intrinsic factors including age, physiological, and genetic features of the patient as well as extrinsic factors such as the intake of drugs and exposure to environmental agents modulate this disorder. It has been proven that diseases, such as mastocytosis, defects in HLA, or filaggrin genes, increase the risk of severe allergic episodes. Certain allergen families such as storage proteins, lipid transfer proteins, or parvalbumins have also been linked to anaphylaxis. Environmental factors such as inhaled allergens or sensitization through the skin can exacerbate or trigger acute anaphylaxis. Moreover, the effect of dietary habits such as the early introduction of certain foods in the diet, and the advantage of the breastfeeding remain as yet unresolved. Interaction of allergens with the intestinal cell barrier together with a set of effector cells
Anaphylaxis is the medical term for severe allergic reaction. Anaphylaxis, if left untreated, can turn out to be fatal, hence it should be attended with utmost care and sensitivity. Unfortunately, severe anaphylaxis is so rare that more often than not people are not aware what to do if they come across someone who is under an anaphylaxis. This is the reason why we have come out with this article in which we have listed some of the most effective first aid procedures that are highly effective in an event of anaphylaxis. While administering first aid for anaphylaxis, it is important that you bear in mind that it is a potentially fatal condition and hence you should seek emergency help immediately. Emergency help means calling 911 for ambulance so that the person can be taken to the nearest medical centre. Anaphylaxis can be treated quickly by administering prescribed medicines; hence if you do not know how to do it then you have to take the person to the nearest medical unit. Often people get confused in
Our data indicate that bradykinin production is increased during cardiac anaphylaxis, a reaction characterized by the release of several coronary-vasoconstricting mediators. The following findings define the functional consequences of this increased bradykinin production: (1) HOE 140 potentiates anaphylactic coronary vasoconstriction and exacerbates arrhythmias. (2) When the half-life of bradykinin is prolonged with captopril and enalaprilat, anaphylactic coronary vasoconstriction is greatly diminished, or even reversed, and arrhythmias are alleviated. (3) HOE 140 prevents the effects of the kininase II/ACE inhibitors. Accordingly, we postulate that bradykinin functions as a mitigating factor in cardiac anaphylaxis by opposing the coronary-vasoconstricting effects of other mediators.. Given the potent coronary-vasodilating effects of bradykinin7 and the likelihood that this peptide is a mediator of immediate hypersensitivity,13 we questioned whether local bradykinin production is augmented ...

Background and Objectives: Anaphylaxis, a severe allergic disease, can be triggered by various causes. This study investigated the association between allergic sensitization and anaphylactic symptoms and the severity of anaphylaxis in children.Patients and Methods: A retrospective review of 107 pediatric patients with anaphylaxis was performed between January 1, 2015, and December 31, 2017; 74 patients underwent allergen testing for specific immunoglobulin E. Allergic sensitizations and associations with anaphylactic symptoms and severity were investigated.Results: Overall, 64 (86.5%) patients were sensitized to food or inhalant allergens. In children under 2 years of age, 90.5% were sensitized to food (P = 0.001); in those over 6 years of age, 84.6% were sensitized to inhalant allergens (P = 0.001). Milk sensitization was significantly associated with severe anaphylaxis (P = 0.036). The following symptoms showed significant associations with certain allergen sensitizations: facial edema with food;
60. Is anaphylaxis the same as anaphylactic shock?. No. Anaphylaxis can result in anaphylactic shock but it often doesnt. When talking about anaphylactic shock, people are referring to circulatory shock that was caused by anaphylaxis. Circulatory shock occurs when there is not enough blood to carry oxygen to all the tissues that need it. When the tissues dont get enough oxygen, your organs stop working correctly.. Circulatory shock is usually caused by low blood pressure. Anaphylaxis commonly causes low blood pressure and that can cause shock. However, anaphylaxis does not always cause low blood pressure, and it does not always cause shock.. 61. If a tryptase level over 10.9 ng/mL is high, why is one of the criteria for systemic mastocytosis a tryptase level of 20.0 ng/mL or higher?. Tryptase level is used in two ways in assessing mast cell patients: as a marker for activation, and as a marker for how many mast cells are in the body.. There are two primary methods of using tryptase to indicate ...
Natural latex rubber products have been known to cause severe anaphylactic reactions during surgery. Even 25 years after the first description of anaphylactic reactions in the literature, natural latex rubber products are still used in pediatric surgery. The following article describes the case of a healthy 4.5-year old Caucasian boy who simultaneously developed severe hypotension, tachycardia and bronchospasm during surgery for congenital strabismus sursoadductorius under uneventful anesthesia. An allergy test conducted afterwards showed natural latex rubber as the trigger for this severe intraoperative anaphylactic reaction. This case was special because of the absence of any previous clinical or anamnestical evidence of natural latex rubber allergy. The fact that the child had been previously exposed to natural latex rubber - because the boys mother used disposable gloves for her work as a cosmetician at home - was only discovered later. Such contact may have had a slight sensitizing effect that

ANAPHYLAXIS IS A LIFE-THREATENING TYPE OF ALLERGIC REACTION Can occur at any time. Risks include a history of any type of allergic reaction. Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. INCIDENCE 1 million cases of venom anaphylaxis 0.4 million cases of nut anaphylaxis up to age 44 years worldwide. Approximately 20 anaphylaxis deaths reported each year in the UK (specific causes of anaphylaxis -prevalence and severity data available) PROGNOSIS Overall prognosis of anaphylaxis is good. Case fatality ratio of less than 1% reported in most population-based studies. Risk of death is, however, increased in those with pre-existing asthma, particularly if the asthma is poorly controlled or In asthmatics who fail to use, or delay treatment with adrenaline.
Anaphylactoid Reactions: Sudden and potentially life-threatening anaphylactoid reactions have occurred in some patients dialyzed with high-flux membranes treated concomitantly with an ACE inhibitor. In such patients, dialysis must be stopped immediately, and aggressive therapy for anaphylactoid reactions must be initiated. Symptoms have not been relieved by antihistamines in these situations. In these patients, consideration should be given to using a different type of dialysis membrane or a different class of antihypertensive agent. Anaphylactoid reactions have also been reported in patients undergoing low-density lipoprotein apheresis with dextran sulfate absorption and in patients undergoing desensitizing treatment with hymenoptera venom ...
To the Editor: Indocyanine-green is used for determination of cardiac output, liver function testing, chorioidal angiography, and capillary microscopy. We report three cases of patients with anaphylactoid reactions to indocyanine-green, which together with reports in the literature suggest a dose-dependent pseudoallergic mechanism, rather than a true immune mechanism.. A 49-year-old man received indocyanine-green, 5 mg/kg body weight for capillary microscopy. Within 10 seconds, he developed flush, dyspnea, and shock.. A 56-year-old man received indocyanine-green, 0.5 mg/kg for liver function testing. Within 1 minute, he developed acute bronchospasm, hypotension, and cardiorespiratory arrest.. A 62-year-old man received indocyanine-green, 0.5 mg/kg for liver ...
Anaphylaxis is widely understood to be an immediate life-threatening condition that can occur at all ages and frequently in subjects with a history of atopy. Data about the prevalence of the various causes of anaphylaxis is scarce, especially in children. In adults some reasonable estimates report that hymenoptera sting anaphylaxis occurs in 0.4% of the population6 and penicillin-induced anaphylaxis occurs every 10-50 cases/100 000 injections.7 In a review of patients admitted to a university hospital during 1 year there were 9 cases of anaphylaxis out of 20 000 admissions.8 In a retrospective study carried out among adult subjects, Sorensen et al9 have reported an incidence of 3.4 cases/100 000 inhabitants of anaphylactic shock per year that occurred in a hospital catchment area over a 13-year period. The precipitating agents were penicillin in 7 cases, aspirin in 3 cases, food in 2 cases, and bee or wasp stings in 8 cases. In one study of 172 anaphylactic reactions, foods, especially nuts, ...

AU - Kim, Jae Hong. AU - You, Hye Jin. AU - Choi, Il Whan. AU - Im, Suhn Young. AU - Lee, Hern Ku. PY - 2008/11. Y1 - 2008/11. N2 - Background: We have recently reported that tumor necrosis factor (TNF)-α plays an important role in the development of a late anaphylactic reaction, but the downstream pathway beyond TNF-α remains unclear. Objective: It was the aim of this study to examine whether TNF-α induces late-phase anaphylaxis via the activation of cytosolic phospholipase A 2 (cPLA2). Methods: Using a murine model of active systemic anaphylaxis to penicillin V, the induction of the late phase of anaphylaxis was quantified by measuring the increase in hematocrit value as well as the plasma level of platelet-activating factor in TNF-α knockout mice. Phosphorylation of mitogen-activated protein kinases (MAPKs) ...
Members of Parliament pass Anaphylaxis Awareness Motion. Canadian Anaphylaxis Initiative pleased with step in right direction. May 23, 2013 - OTTAWA - MPs votes in the House of Commons last night included the passing of Motion 230, a motion to raise awareness of anaphylaxis, a life-threatening medical condition brought on by severe allergies. This is welcomed news for family members of the Canadian Anaphylaxis Initiative (CAI), a volunteer network of concerned families who have been working with MPs to raise awareness of severe allergies in Ottawa.. The anaphylaxis motion passed with unanimous, all-Party support. Niagara West-Glanbrook MP Dean Allison initiated the debate in the House of Commons, moving: That in the opinion of the House, anaphylaxis is a serious concern for an increasing number of Canadians and the government should take the appropriate measures necessary to ensure these Canadians are able to maintain a high quality of life.. By bringing more attention and awareness to the ...
We attempted to elicit active anaphylaxis to ovalbumin, or passive IgE- or IgG1-dependent anaphylaxis, in mice lacking either the Fc epsilonRI alpha chain or the FcR gamma chain common to Fc epsilonRI and Fc gammaRI/III, or in mice lacking mast cells (KitW/ KitW-v mice), and compared the responses to those in the corresponding wild-type mice. We found that the FcR gamma chain is required for the death, as well as for most of the pathophysiological changes, associated with active anaphylaxis or IgE- or IgG1-dependent passive anaphylaxis. Moreover, some of the physiological changes associated with either active, or IgG1-dependent passive, anaphylactic responses were significantly greater in Fc epsilonRI alpha chain -/- mice than in the corresponding normal mice. Finally, while both KitW/KitW-v and congenic +/+ mice exhibited fatal active anaphylaxis, mast cell-deficient mice exhibited weaker physiological responses than the corresponding wild-type mice in both active and IgG1-dependent passive ...
Exercise-induced anaphylaxis (EIA) is a rare disorder in which anaphylaxis occurs after physical activity. The symptoms may include pruritus, hives, flushing, wheezing, and GI involvement, including nausea, abdominal cramping, and diarrhea.

Therefore, it is important to establish a novel method to evaluate drugs for anaphylactoid reactions. In this study, we developed a sensitive and rapid method to detect histamine release from LAD2 cells using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and constructed a relative release index based on various release curve parameters, including allergen release time and sudden change rate, to evaluate the potential and ...
Anaphylactoid reactions occur rarely,[4][5][6] but can occur in response to injected as well as oral and rectal contrast and even retrograde pyelography. They are similar in presentation to anaphylactic reactions, but are not caused by an IgE-mediated immune response. Patients with a history of contrast reactions, however, are at increased risk of anaphylactoid reactions.[7][8] Pretreatment with corticosteroids has been shown to decrease the incidence of adverse reactions.[9][10] Anaphylactoid reactions range from urticaria and itching, to bronchospasm and facial and laryngeal edema. For simple cases of urticaria and itching, an oral or intravenous antihistamine such as diphenhydramine is appropriate. For more severe reactions, including bronchospasm and facial or neck edema, albuterol inhaler, or subcutaneous or IV epinephrine, plus diphenhydramine may be needed. If respiration is compromised, an airway must be established prior to medical management. Anaphylaxis to ionic (high osmolar) ...
As many as 1 in 50 people are at risk for anaphylaxis which is a severe, rapidly progressive, potentially life threatening allergic reaction. Anaphylaxis can occur from a variety of substances such as foods, medications, or insect venoms. Signs of anaphylaxis can include hives, swelling, shortness of breath, coughing, dizziness, low blood pressure or passing out. People are not born allergic to these substances but can become susceptible to developing an allergy after exposure. If a patient is concerned they may have a severe allergy to something, they should see a board certified allergist who will take a detailed allergic history and perform any allergy testing to determine if the patient is truly allergic. If a patient is found to be at risk for anaphylaxis, they will be taught how to avoid the allergen(s), receive an anaphylaxis action plan that provides guidance on how to treat an allergic reaction should it occur, wear medical alert jewelry that describes their anaphylactic condition, and ...
Anaphylaxis is a serious allergic reaction that has a rapid onset and can cause death.1,2 In the past, the term anaphylactic reaction referred to symptoms triggered by immunoglobulin (Ig) E-dependent activation of immune effector cells, whereas anaphylactoid reactions were clinically similar to anaphylactic reactions but were not mediated by antigen-specific IgE. Although some experts have advocated that the term anaphylactoid be eliminated, other influential clinical practice guidelines consensus documents continue to use the term anaphylactoid - thus, anaphylactic and anaphylactoid reactions will be discussed as a single entity in this chapter. 2 ...
Anaphylaxis is a medical emergency and among the most severe diseases dealt with by allergists. In a nearly global manner and for reasons not fully understood, the incidence of anaphylaxis has increased [3-5], as has its severity [6-8]. This explains the growing interest in epidemiological surveys to map the problem in several populations.. According to estimates, one out of 200 emergency care cases are caused by hypersensitivity reactions, ranging from mild urticaria to true anaphylactic reactions [16]. Epidemiological studies claim an estimated 50-2000 episodes of anaphylaxis per 100,000 persons, and, thus, approximately 2% of the population has already experienced at least one episode of anaphylaxis during their life [17].. The prevalence of anaphylaxis can be studied using data from different sources, such as emergency services, public and private medical facilities, hospital admissions, and consultations in allergist offices. Thus, the different methodologies must be considered when ...
Anaphylaxis is a severe, life-threatening, systemic allergic reaction that is almost always unanticipated and may lead to death by airway obstruction or vascular collapse. Anaphylaxis occurs as the result of an allergen response, usually immunoglobulin E-mediated, which leads to mast cell and basophil activation and a combination of dermatologic, respiratory, cardiovascular, gastrointestinal, and neurologic symptoms. Dermatologic and respiratory symptoms are most common, occurring in 90 and 70 percent of episodes, respectively. The three most common triggers are food, insect stings, and medications. The diagnosis of anaphylaxis is typically made when symptoms occur within one hour of exposure to a specific antigen. Confirmatory testing using serum histamine and tryptase levels is difficult, because blood samples must be drawn with strict time considerations. Allergen skin testing and in vitro assay for serum immunoglobulin E of specific allergens do not reliably predict who will develop anaphylaxis.
An erroneous belief exists that epinephrine fixes anaphylaxis, thereby obviating the need for further evaluation and treatment in the emergency department. To undermine this belief, one must consider the pathogenesis of anaphylaxis [9].. Anaphylaxis results from the cascade-like activation of immune cells in the body after exposure to a particular allergen. The most common triggers for fatal reactions are foods, drugs, and stings [1, 10]. Children and adolescents carry a higher risk of fatal anaphylaxis due to food reactions, while older individuals are more likely to die from venom or drug reactions [8, 10, 11]. The triggering allergen starts the reaction by stimulating a response in a particular type of antibody (IgE), which bind both the allergen and sites on the surface of mast cells and basophils (immune cells), causing their activation. The activated immune cells quickly release a variety of potent chemicals into the body, including histamine and tryptase. As the reaction progresses, the ...
The diagnosis of anaphylaxis is based primarily on the clinical history. In some circumstances, inability to confirm the clinical diagnosis such as present with unusual manifestation, or when skin signs are absent likely contributes to underrecognition and undertreatment of the disease.. Currently, products of mast cell activation (histamine and total tryptase) can be measure in clinical laboratories as markers of acute anaphylaxis events, however these tests have clinically relevant limitations.. Therefore, development of laboratory tests with improved sensitivity and specificity that will support the clinical diagnosis of anaphylaxis are needed.. In addition, shrimp is the major cause of seafood anaphylaxis among Thai children. ...

Objective: To determine which patients are most likely to receive repeated doses of epinephrine during anaphylaxis management. Methods: A population-based study with medical record review was conducted. All patients seen during the study period who met the criteria for the diagnosis of anaphylaxis were included. Results: The cohort included 208 patients (55.8% female). Anaphylaxis treatment included epinephrine in 104 patients (50.0%). Repeated doses were used in 27 patients (13.0%), 13 (48.1%) of them female. The median age of those who received repeated doses was 18.9 (interquartile range, 10-34) years vs ...
To the best of our knowledge, this is the first case demonstrating FDEIA due to chickpea in an adolescent patient, and only the second case overall reporting FDEIA due to chickpea. The first case was identified in a 41-year-old woman after dancing [11]. Legumes are not a common food associated with FDEIA, and there are minimal reports in the literature. Of interest, Orhan and Karakas discuss a 17-year-old with FDEIA to lentils [9]. Adachi et al. describe the first known case of FDEIA induced by soybean products in a 16-year-old girl who ate tofu [8]. So far, FDEIA is more common in adolescents and adults, but should not be overlooked when assessing younger patients [6].. This case demonstrates the challenge in identifying specific causative food allergens when foods are eaten in combination and when a potential allergen is contained in processed food. Rice crackers and hummus were the suspected foods and therefore several potential allergens were investigated based on their ingredients: wheat, ...
Anaphylaxis is a serious allergic reaction that happens when you are exposed to an allergen. It is estimated that up to 2% of the world population might experience anaphylaxis during their life time. Based on estimates, the condition is the cause of 1500 deaths each and every year.. Actress Julie Bowen, together with Mylan Specialty L.P. recently launched a competitionRaise Your Hand for Anaphylaxis Awareness to make people aware of the condition. They have created a special website where people can share their personal stories about it and tell why they think the awareness is important. As part of the campaign, four school districts will also be receiving a grant of $15 000 towards educational programs. The competition is open until October 1, 2013. The winners will be selected based on which school districts have the most individuals participating.. How can You Raise Your Hand for Anaphylaxis Awareness? Go to, sign in and choose your school ...
NC - According to Health Canada, close to 6 percent of Canadian children have a food allergy.. Greater public awareness and understanding of anaphylaxis could help save lives.. Elizabeth Monk, a spokesperson for Allerject, notes that the seriousness of anaphylaxis is generally not well understood. Many people dont know that it can be life-threatening. And many are uncertain about how allergic reactions are triggered, how to spot the symptoms, and what to do in an emergency, she says.. How much do you know about severe allergic reactions? Take the Allergy Quiz. Youll find the full quiz at as well as additional resources and information about anaphylaxis.. Here are a few sample questions to get you going.. 1.

Acute Systemic Anaphylaxis Anaphylaxis is a systemic allergic reaction involving the respiratory and/or the cardiovascular system; it has a rapid onset
Anaphylaxis is triggered by certain types of food, drugs, insects or other items that contain allergens. Symptoms can include widespread hives, coughing, difficulty breathing, wheezing and gastrointestinal issues. In severe cases symptoms include lethargy, dizziness and hypotension, which are rare in children.. The study, due to be published in the Journal of Allergy and Clinical Immunology: In Practice later this month, will aim to bridge the gap in knowledge about childhood anaphylaxis, with lead researcher Dr. Aikaterini Anagnostou saying the study has a focus on reports of anaphylaxis in children only, specifically examining triggers and management approaches.. To conduct the study, 275 cases of childhood anaphylaxis in children aged birth - 18 years were retrospectively reviewed. The researchers found that triggers for anaphylaxis can differ based on geographical region. According to the study, the top trigger for this population is tree nuts, such as cashew and walnut. This is interesting ...
Background. Two deaths in Ontario during the summer of 1994 caused by a severe peanut allergy have heightened awareness of the serious hazard of anaphylaxis.. Anaphylaxis is an acute systemic (whole body) allergic reaction, which has a collection of symptoms affecting multiple systems in the body. It occurs when a person has become sensitized (i.e. the immune system has been triggered to recognize a substance as a threat to the body). The most dangerous symptoms are breathing difficulties and a drop in blood pressure or shock, both of which are potentially fatal. Common examples of potentially life-threatening allergies are certain foods and insect bites/stings. However, these severe allergic reactions may also be caused by medications, exercise, chemicals (especially volatile organic compounds - VOCs, and solvents) and latex ...

TY - JOUR. T1 - Regulation of plasma histamine levels by the mast cell clock and its modulation by stress. AU - Nakamura, Yuki. AU - Ishimaru, Kayoko. AU - Shibata, Shigenobu. AU - Nakao, Atsuhito. PY - 2017/1/11. Y1 - 2017/1/11. N2 - At steady state, plasma histamine levels exhibit circadian variations with nocturnal peaks, which is implicated in the nighttime exacerbation of allergic symptoms. However, the regulatory mechanisms are largely unexplored. This study determined how steady-state plasma histamine levels are regulated and affected by environmental factors. We found that plasma histamine levels decreased in mast cell-deficient mice and their circadian variations were lost in mast cell-deficient mice reconstituted with bone marrow-derived mast cells (BMMCs) harboring a mutation in the circadian gene Clock. Clock temporally regulates expression of organic cation transporter 3 (OCT3), which is involved in histamine transport, in mast cells; OCT inhibition abolished circadian variations in ...

BACKGROUND Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) have been reported to enhance the symptoms of wheat-dependent exercise-induced anaphylaxis (WDEIA). In contrast to many reports on WDEIA, there have been only a few reports of wheat-dependent aspirin-induced anaphylaxis not induced by the combination of wheat and exercise. METHODS Two patients with wheat-dependent anaphylaxis underwent provocation tests to clarify the cause of their symptoms. Skin-prick testing (SPT) was also performed with and without administration of aspirin. Specific IgE antibody to wheat, gluten, and omega-5 gliadin were examined. RESULTS In the provocation tests, anaphylactic reactions were not induced by wheat or aspirin alone or by the combination of wheat and exercise, but were induced by the combination of wheat and aspirin. An increase in the blood histamine level was detected after provocation in both patients. Pretreatment with aspirin enhanced the SPT reactions to wheat and gluten in both

Hypersensitivity reactions (HR) are immune responses that are exaggerated or inappropriate against an antigen or allergen. Coombs and Gell classified hypersensitivity reactions into four forms. Type I, type II, and type III hypersensitivity reactions are known as immediate hypersensitivity reactions (IHR) because occur within 24 hours. Antibodies including IgE, IgM, and IgG mediate them.[1]. Type I or Anaphylactic Response. Anaphylactic Responseis mediated by IgE antibodies that are produced by the immune system in response to environmental proteins (allergens) such as pollens, animal danders or dust mites. These antibodies (IgE) bind to mast cells and basophils, which contain histamine granules that are released in the reaction and cause inflammation. Type I hypersensitivity reactions can be seen in bronchial asthma, allergic rhinitis, allergic dermatitis, food allergy, allergic conjunctivitis, and anaphylactic shock.[2][3]. Anaphylaxis. Anaphylaxis is a medical emergency because can lead to an ...
Hypersensitivity Reactions: Hypersensitivity reactions including allergic/and anaphylactoid reactions can occur with the use of TISSEEL. Cases have been reported in post marketing experience with Baxters fibrin sealant.In specific cases, these reactions have progressed to severe anaphylaxis. Such reactions may especially be seen if TISSEEL is applied repeatedly over time or in the same setting, or if systemic aprotinin has been administered previously. Even if the first treatment was well tolerated, this may not exclude the occurrence of an allergic reaction after a subsequent administration of TISSEEL or systemic aprotinin. Observed symptoms of allergic anaphylactic reactions to TISSEEL have included: bradycardia, tachycardia, hypotension, flushing, bronchospasm, wheezing, dyspnea, nausea, urticaria, angioedema, pruritus, erythema and paresthesia. Such reactions can also occur in patients receiving TISSEEL for the first time ...
Adverse reactions to food, that is, food allergy and intolerance have gained considerable attention. Food allergy is believed to be responsible for most immediate-type food-induced hypersensitivity reactions. Clinically, these reactions are characterized by a variety of signs and symptoms that occur within minutes or hours after consumption of the offending food. Reactions may be limited or more generalized with involvement of the skin, nose, eyes, and/or lungs. In more severe cases, cardiovascular symptoms including hypotension, shock, cardiac dysrhythmias, and death can occur. In food-allergic individuals, IgE is produced against naturally occurring food components, primarily glycoproteins that usually retain their allergenicity after heating and/or proteolysis [2].. Whereas in the United States, peanuts and tree nuts (walnuts, pecans, pistachios, cashews, and others) are responsible for the majority of severe anaphylactic reactions, followed by shellfish (crustaceans and mollusks) and fish, ...
Risk of Anaphylactic Reaction While taking beta-blockers, patients with a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated challenge, either accidental, diagnostic, or therapeutic. Such patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction.. Impaired Renal of Hepatic Function Studies on the effect of acebutolol in patients with renal insufficiency have not been performed in the U.S. Foreign published experience shows that acebutolol has been used successfully in chronic renal insufficiency. Acebutolol is excreted through the GI tract, but the active metabolite, diacetolol, is eliminated predominantly by the kidney. There is a linear relationship between renal clearance of diacetolol and creatinine clearance. Therefore, the daily dose of acebutolol should be reduced by 50% when the creatinine clearance is less than 50 mL/min and by 75% when it is less than 25 mL/min. Acebutolol should be used cautiously in ...
an″ă-fĭ-lak′sĭs) [ana- + (pro)phylaxis] A sudden, severe allergic reaction between an allergenic antigen and immunoglobulin E (IgE) bound to mast cells, which stimulates the sudden release of immunological mediators locally or throughout the body. The first symptoms occur within minutes, and a recurrence may follow hours later (late-stage response). Anaphylaxis can only occur in someone previously sensitized to an allergen because the initial exposure causes immunoglobulin E (IgE) to bind to mast cells. Anaphylaxis may be local or systemic. Local anaphylactic reactions include hay fever, hives, and allergic gastroenteritis. Systemic anaphylaxis produces peripheral vasodilation, bronchospasm, and laryngeal edema and can be life-threatening. anaphylactic (an″ă-fĭ-lak′tik), adj. ...
Despite strict avoidance, severely food-allergic children experience frequent and potentially severe food-induced anaphylaxis (FSFA). There are no accepted preventive interventions for FSFA. A Traditional Chinese Medicine (TCM) formula prevents anaphylaxis in murine food allergy models, and has immunomodulatory effects in humans. We analyzed the effects of TCM treatment on three pediatric patients with FSFA. Three FSFA patients (P) ages 9-16 years (P1 allergic to milk; P2 and P3 to tree nuts) qualified for case analysis. All experienced numerous reactions requiring administration of rescue medications and emergency room (ER) visits during the 2 years prior to starting TCM. P1 experienced approximately 100 reactions, 50 epinephrine administrations, 40 ER visits, and 3 admissions to intensive care units. P2 experienced 30 reactions, all requiring epinephrine administration, as well as 10 emergency hospitalizations. P3 experienced 400 reactions, five of which required epinephrine administration and ER
At least a third of reactions in children with food-induced anaphylaxis to a known allergen occur under adult supervision, according to new research led by AllerGen researchers using data from AllerGens nationwide Cross-Canada Anaphylaxis REgistry (C-CARE).. The study, published in the November issue of Pediatric Allergy and Immunology, found that inadvertent exposures to a known food allergen in children are frequent, and in the majority of supervised reactions, adults other than the childs parents were present..

There is a controversy associated with the effects of immunotherapy aimed at desensitising patients to house dust mites on their reactions to snails and other molluscs and crustacea. Van Ree et al. (1996) [1713] first reported that house-dust mite immunotherapy is accompanied by the induction of IgE against snail and shrimp. Out of 17 sera over a 14-20 month study, the average IgE response to snail showed a significant increase and this included two conversions from negative to strongly positive. The IgE response to snail (, 10% binding in a snail RAST) was confirmed by a positive skin prick test (SPT) for 6/10 patients. 2 patients also showed oral allergy syndrome on eating shrimp (Crangon crangon).. Peroni et al. (2000) [1667] report the case of a 12-year-old girl who was sensitized to house dust mites and started immunotherapy. After several months the patient was taken to the hospital emergency room owing to severe anaphylactic reaction after ingestion of sea snails. She developed a ...
Anaphylaxis is a severe, rapidly progressive allergic reaction that is potentially life threatening. The most common allergens in school aged children are peanuts, eggs, tree nuts (e.g. cashews), cows milk, fish and shellfish, wheat, soy, sesame and certain insect venom (particularly bee stings).. The key to prevention of anaphylaxis in schools is knowledge of the student who has been diagnosed as at risk, awareness of allergens, and prevention of exposure to those allergens. Partnerships between schools and parents/guardians are important in helping the student avoid exposure.. Adrenaline given through an adrenaline auto-injector (such as an EpiPen® or Anapen®) into the muscle of the outer mid-thigh is the most effective first aid treatment for anaphylaxis.. ...
If ISM is life threatening, why is not considered as dangerous as ASM or MCL?. ISM is not life threatening. Anaphylaxis is life threatening. They are not the same. Many people with ISM never experience anaphylaxis. ISM can make anaphylaxis more dangerous, but ISM is not the same as anaphylaxis. Outside of anaphylaxis, ISM is not life threatening.. Indolent systemic mastocytosis (SM) patients have a varied clinical presentation, ranging from predominantly cutaneous symptoms to recurrent systemic symptoms (eg, flushing, palpitations, dyspepsia, diarrhea, bone pain) that can be severe and potentially life threatening (anaphylaxis.) (Pardanini 2013). Is MCAS more or less dangerous than ISM?. From a clinical standpoint, MMAS and MCAS share many similarities with systemic mastocytosis (SM), a primary disorder of mast cells in which patients experience symptoms ranging from pruritus and flushing to anaphylaxis. (Picard 2013). Again, the real danger here is anaphylaxis rather than these entities ...
It is now widely known that blockade of CysLT1 receptors strongly inhibits antigen-induced bronchial contractions in specimens isolated from non-asthma subjects. However, this blockade is not complete as shown in the present study and in other literature.4, 15, 16 The results of the current study suggest that CysLT2 receptors activation has no significant role in the bronchial contractions recorded in the non-asthma specimens. On the other hand, in one of the two Pyridoxal isonicotinoyl hydrazone mg specimens, CysLT2 receptors blockade inhibited anaphylactic bronchoconstriction. This inhibition was potentiated by dual blockade of CysLT1 and CysLT2 receptors. These results suggest that there may be a certain asthma background, in which activation of CysLT2 receptors is involved in anaphylactic bronchocontractile response, and thus may play a significant role in asthma response in certain asthma population. It is not clear why the involvement of CysLT2 receptor activation in anaphylactic response ...
Insect stings and bites are an expected summertime nuisance. Stinging insects include honey bees, wasps, hornets and yellow jackets. Biting insects include mosquitoes, fleas, flies, chiggers, ticks and spiders.. Insect stings usually result in a local skin reaction as a result of venom injected by the stinger. A reddened, painful area with an itchy sensation may develop that lasts about four to five days. Multiple stings can result in a more generalized reaction that includes vomiting, diarrhea, generalized swelling and collapse. Infection can develop from scratching. The most dangerous reaction to a sting is a severe allergic reaction called anaphylaxis. Symptoms include hives, flushing, itching, face and neck swelling, nausea, fever, and shortness of breath. Stings in the mouth and throat are of special concern because local swelling may block the breathing passages. Anyone suspecting anaphylaxis or having breathing difficulty after an insect sting should call 911 or be taken to the nearest ...
A 34-year-old man presented with significant intra-abdominal and orthopaedic injuries following a high-speed motorbike crash. The man had a history of an anaphylactic reaction to iodine. As a result, the gold standard CT of the abdomen with contrast was unable to be performed to ascertain the exact nature of the intra-abdominal injuries. After stabilisation, an MRI of the abdomen was performed which localised the injuries. The previous contrast anaphylaxis delayed full assessment of the patient and subsequent management.

Editor,. Insect venoms commonly cause immunoglobulin E-mediated anaphylactic reactions. Increased vascular permeability may lead to urticaria, dyspnoea and hypotension. In severe cases, anaphylaxis can be life threatening due to airway and cardiovascular compromise. Gastrointestinal symptoms are rarely reported and seldom detected, although mucosal damage in anaphylactic reactions is well recognised.1. Prior to submission of this case report, the patient consented for the publication. The husband of a 57-year-old female patient in respiratory distress following a hornet sting in the right eyelid called the local emergency medical service for help. He had performed vigorous mouth-to-mouth ventilation to his still conscious wife before the arrival of emergency medical service; he subsequently stated that it had been difficult to get air into his wifes lungs. The emergency physician diagnosed anaphylaxis with obstructed upper airways. The patient immediately received intravenous corticosteroid and ...
Co-inhibitory molecules such as PD1, PD-L1 and CTLA-4 are being increasingly used as targets of therapeutic intervention against cancer. The use of monoclonal antibodies targeting these immune checkpoints has been shown to promote anti-tumor immune responses clinically. While these promising results have led to a critical paradigm shift in treatments for cancer, these approaches are also plagued with limitations owing to cancer immune evasion mechanisms and adverse toxicities associated with continuous treatment. It has been difficult to reproduce and develop interventions to these findings preclinically for many reasons including species/age-related differences in expression of these markers, poor tumor modeling, and reagent xenogenicity. In this study, we investigated adverse effects in mice receiving repeated anti-PD1 (clone J43) or PD-L1 (clone 10F.9G2) monoclonal antibody (mAb) administration in the 4T1 mouse model of mammary carcinoma. Mice bearing day 14 syngeneic mammary carcinomas were ...
Other abnormalities that can be noted secondary to anaphylaxis are an increase in serum alanine transaminase (ALT), hemoabdomen, vomiting, diarrhea as well as cutaneous signs. Although cutaneous signs are absent in nearly 95% of cases. The elevation in ALT typically lags several hours, therefore it cannot be relied upon in the immediate diagnosis of anaphylaxis. The mean value for ALT is 400 IU/L in anaphylactic canines. The hepatic venous congestion along with factors that contribute to acquired coagulopathy leads to a hemoabdomen. Unfortunately, gallbladder wall edema is not pathognomonic for canine anaphylaxis. In an acutely collapsed or hypotensive canine with gallbladder wall edema, you must rule out other differentials such as pericardial effusion, right-sided heart failure or dilated cardiomyopathy. The caudal vena cava can help determine the cause of the gallbladder wall edema because it is an indirect marker of volume status and central venous pressure. In anaphylaxis the caudal vena ...
Mast cells play a key role in allergic reactions due to their ability to synthesize and release proinflammatory mediators and cytokines (1-3). Upon exposure to allergens, specific IgE bound to FcεRI on mast cells becomes cross-linked and intracellular signals are transduced that lead to cellular activation. These intracellular signals are tightly regulated, as spurious signals could result in unwanted, and possibly deleterious, responses. Although recent work has identified many of the proteins that positively regulate FcεRI signaling, little is known about the negative regulators of these signaling cascades. In this study, we have identified a physiological role for PIPKIα as a negative regulator of FcεRI-mediated mast cell functions. BMMCs from PIPKIα-deficient mice exhibit enhanced degranulation and cytokine gene expression. As a result, loss of PIPKIα culminates in aggravated systemic and local passive anaphylaxis in vivo.. PIPKIs are lipid kinases that are critical for intracellular ...
A severe allergic reaction may follow oral or parenteral administration of a drug. Anaphylactic reactions in dentistry may follow the administration of a drug or contact with substances such as latex in surgical gloves. In general, the more rapid the onset of the reaction the more profound it tends to be. Symptoms may develop within minutes and rapid treatment is essential.. Anaphylactic reactions may also be associated with additives and excipients in foods and medicines. Refined arachis (peanut) oil, which may be present in some medicinal products, is unlikely to cause an allergic reaction-nevertheless it is wise to check the full formula of preparations which may contain allergens (including those for topical application, particularly if they are intended for use in the mouth or for application to the nasal mucosa).. ...
Insect stings can generate a range of immune and clinical reactions. Most reactions are local and self-limiting. Allergic reactions to insect stings can occur at all ages, with or without previous stings. Individuals with a history of anaphylaxis carry a significant risk of life-threatening anaphylaxis with future stings. Health-care providers are often unaware of the tremendous clinical benefits of venom immunotherapy for these select patients. Scientific knowledge about the natural history, risk factors, and optimal therapy for insect sting allergies has improved considerably in recent years. ...

Based on recent reports, Food Allergy Research and Education (FARE) estimates that 15 million Americans have food allergies and that severe allergic reactions account for more than 200,000 emergency room visits each year. To go along with this, more than 17 million Europeans have a food allergy, and hospital admissions for severe reactions in children have risen seven-fold over the past decade in Europe alone.. While researchers are trying to discover why food allergies are on the rise and potential ways a food allergy could be cured, there are still no clear answers. Strict avoidance and early recognition of foods that cause allergic reactions are the most important factors health professionals recommend today, as well as knowing what to do when a server reaction takes place.. In the most severe reactions, anaphylaxis occurs, which threatens the breathing and blood circulation of the individual experiencing the allergic reaction. Anaphylaxis can set in within just minutes after an allergic ...
Melanies research is well aligned with the Universitys key theme of Better Health. Her primary research is in the area of bioactive food and nutrition. The primary aim is to understand the impact of bioactive food components, specifically anthocyanins and the impact these compounds have on health and human disease. Melanie is particularly interested in inflammation and how functional foods may impact this. This research is currently being undertaken in partnership with industry.. Melanies work as part of the allergy and anaphylaxis research group (AARG) aims to build a greater understanding of the presentation of anaphylaxis in the community. How anaphylaxis is managed following diagnosis, how members of the community affected by anaphylaxis are supported, as well as patient and community education, are particular focuses. The overarching aim of the group is to improve current practice by aiding the development of evidence-based clinical practice guidelines for health professionals and ...

By 1853, Parliament began passing laws to make the untested vaccine compulsory throughout the British Empire. Other countries of Europe followed suit. Once the economic implications of compulsory vaccinations were realized, few dared to disagree.

Breathing emergencies make up a small portion of emergency, childcare and standard first aid courses (register for a standard first aid course with Vancouver First Aid). However, with respiratory emergencies being the primary concern with children and infants I thought I would spend some time explaining the simplicity in treating respiratory emergencies. Respiratory emergencies include anaphylaxis, aspiration, asthma and hyperventilation.. Anaphylaxis is a very treatable condition but that can also be somewhat confusing to recognize. Anaphylaxis is an allergic reaction. Severe allergens include consumption of dairy, fish and nuts and environmental situations such as bee stings or other bites. The signs and symptoms of anaphylaxis can be tricky to determine because they are different for each person and can be different for each episode. Typically symptoms include redness and itchiness starting on the victims back and swelling of the lips and mouth. Anaphylaxis is included in breathing ...
Terlipressin is a synthetic derivative of vasopressin. It is a prodrug that is converted to lysine vasopressin in the circulation after the N-triglycyl residue is cleaved by endothelial peptidases.21 This results in a rapid and sustained release of the structural analog lysine vasopressin. The reason for which terlipressin was investigated in the current study is that despite differences with AVP for its hemodynamic effects, terlipressin has been used as an alternative to exogenous AVP, especially in France, where AVP is not commercially available.12,22-25 Unexpectedly, terlipressin, which has been reported to be effective in catecholamine-resistant septic shock in adults12,24,26,27 and in children,28 did not increase MAP values during anaphylactic shock, regardless of the dose injected. The lack of increase of MAP in terlipressin-treated animals explains the shorter duration of the experiments as compared with the two other groups. The explanations for this lack of MAP effect are not clear. In ...
The answer is b: Latex anaphylaxis occurs in patients with spina bifida or with congenital urologic defects who have undergone repetitive surgeries. Other groups at risk include employees of rubber manufacturers and health care workers. The diagnosis is confirmed by prick skin testing for IgE to latex or by radioallergosorbent test (RAST) assay. Patients with latex-induced anaphylaxis must avoid latex during surgical procedures and live in a latex-free environment. ...
Epinephrine is a hormone that increases heart rate, contracts blood vessels, and opens air passages. Its more commonly known as adrenaline. According to the American College of Allergy, Asthma & Immunology, epinephrine is the primary treatment for an emergency allergic reaction like anaphylaxis. Anyone with a known insect sting allergy should carry an autoinjection epinephrine kit whenever going anywhere in nature. An epinephrine autoinjector is a combined needle and syringe that makes it easy to deliver a single dose of the medication. Three common brands of auto-injection epinephrine are Anapen, EpiPen, and Twinject.. Its important to remember that epinephrine is a rescue medication only. Its effects are relatively short lived, and, in most cases, further therapy is necessary to prevent recurrence of the life-threatening condition. According to Mayo Clinic, anyone who suffers an anaphylactic reaction to an insect sting should be taken to see a medical professional immediately, whether they ...
VIMIZIM® (elosulfase alfa) is indicated for patients with mucopolysaccharidosis type IVA (MPS IVA; Morquio A syndrome).. IMPORTANT SAFETY INFORMATION. Life-threatening anaphylactic reactions have occurred in some patients during VIMIZIM infusions. Anaphylaxis, presenting as cough, erythema, throat tightness, urticaria, flushing, cyanosis, hypotension, rash, dyspnea, chest discomfort, and gastrointestinal symptoms in conjunction with urticaria, have been reported to occur during VIMIZIM infusions, regardless of duration of the course of treatment. Closely observe patients during and after VIMIZIM administration and be prepared to manage anaphylaxis. Inform patients of the signs and symptoms of anaphylaxis and have them seek immediate medical care should symptoms occur. Patients with acute respiratory illness may be at risk of serious acute exacerbation of their respiratory compromise due to hypersensitivity reactions and require additional monitoring.. Due to the potential for anaphylaxis, ...
Anaphylaxis, a type I IgE-mediated hypersensitivity reaction, is estimated to occur in 1.5-34% of patients sustaining an insect sting[3]. Those at increased risk for severe systemic reactions include those with increased age, prior venom sensitization, underlying cardiovascular disease, and patients with mastocytosis. Symptoms of anaphylaxis may occur as early as 10 minutes or as late as 72 hours after the sting. Early signs and symptoms include generalized urticaria, angioedema, and flushing, and may progress to bronchoconstriction, laryngeal edema manifesting as wheezing, hypotension, cardiovascular collapse, and, potentially, death. Elevated concentrations of serum histamine, tryptase, and mast cells support the diagnosis of anaphylaxis. Immediate intramuscular epinephrine is the initial acute treatment and patients should be discharged with a prescription for an epinephrine auto-injector and clear instructions for use as well as an allergy identification bracelet. Additionally, all patients ...

Coagulopathy: In clinical trials, recurrent coagulopathy (the return of a coagulation abnormality after it has been successfully treated with antivenin), characterized by decreased fibrinogen, decreased platelets, and elevated prothrombin time, occurred in approximately half of the patients studied; one patient required re-hospitalization and additional antivenin administration. Recurrent coagulopathy may persist for 1 to 2 weeks or more. Patients who experience coagulopathy due to snakebite should be monitored for recurrent coagulopathy for up to 1 week or longer. During this period, the physician should carefully assess the need for re-treatment with CroFab® and use of any type of anticoagulant or anti-platelet drug.. Hypersensitivity Reactions: Severe hypersensitivity reactions may occur with CroFab®. In case of acute hypersensitivity reactions, including anaphylaxis and anaphylactoid reactions, discontinue infusion and institute appropriate emergency treatment. Patients allergic to papain, ...
Intravesical Adriamycin treatment was given to 22 patients with carcinoma in situ of the urinary bladder. The treatment schedule consisted of monthly Adriamycin instillations in a dose related to bladder capacity. Endoscopic inspection with multiple bladder biopsies and cytoanalysis of urine was performed after every third instillation. In two patients there was lasting disappearance of the carcinoma in situ. Another 10 patients possibly had a beneficial effect of the treatment. The remaining 10 patients showed persistent malignancy and in 6 of these, progression of carcinoma in situ during Adriamycin treatment necessitated cystectomy or radiotherapy. The histologic and cytologic findings showed distinct variability in most patients, with atypia or even absence of malignant cells often followed by recurrence. Adriamycin was discontinued in four cases because of severe cystitis, and in one case because of an anaphylactoid reaction following instillation of the drug.

Nonallergic rhinitis refers to rhinitis that is not due to an allergy. The category was formerly referred to as vasomotor rhinitis, as the first cause discovered was vasodilation due to an overactive parasympathetic nerve response. As additional causes were identified, additional types of nonallergic rhinitis were recognized. Vasomotor rhinitis is now included among these under the more general classification of nonallergic rhinitis.[14] The diagnosis is made upon excluding allergic causes.[15] It is an umbrella term of rhinitis of multiple causes, such as occupational (chemical), smoking, gustatory, hormonal, senile (rhinitis of the elderly), atrophic, medication-induced (including rhinitis medicamentosa), local allergic rhinitis, non-allergic rhinitis with eosinophilia syndrome (NARES) and idiopathic (vasomotor or non-allergic, non-infectious perennial allergic rhinitis (NANIPER), or non-infectious non-allergic rhinitis (NINAR).[16].

  • The symptoms of idiopathic anaphylaxis are no different from those in cases where the trigger is known and, as with all cases of anaphylaxis, idiopathic anaphylaxis has the potential to be life threatening. (
  • Although likely an underestimate, about 10,000 cases of anaphylaxis occur per year in North America , with about 750 fatalities a year. (
  • [2009 Nov] PHAC confirms 24 cases of anaphylaxis across Canada after H1N1 flu shots There have been 24 confirmed cases of a type of severe allergic reaction called anaphylaxis in Canadians who have received an H1N1 flu shot, including one person who died after getting vaccinated, the head of the Public Health Agency of Canada said Wednesday. (
  • Patients with low BP were prone to having multisystem involvement, whereas the cases of anaphylaxis induced by antibiotics and anesthetics were less likely to involve multiple organ systems. (
  • It has been estimated that EIA may represent 5 percent to 15 percent of all cases of anaphylaxis," says Brian Smart, M.D., an allergist and immunologist at the DuPage Medical Group Asthma and Allergy Center in Glen Ellyn, Ill. Although EIA is uncommon, fitness professionals should be aware of this potentially serious condition and its associated variables. (
  • In the United States, 15 cases of anaphylaxis or anaphlyactoid reactions following HPV vaccination were reported to the Vaccine Adverse Events Reporting System in 2007. (
  • In more than half of cases of anaphylaxis, a clear cause is not identified. (
  • 1 This review aims to help general practitioners and emergency physicians with their approach to acute management and follow-up care in cases of anaphylaxis. (
  • Food, insect venoms or medication trigger most cases of anaphylaxis, with a variable proportion of patients experiencing idiopathic anaphylaxis (in which extensive evaluation fails to identify an underlying cause) ( Box 2 ). (
  • Between 500 and 1000 fatal cases of anaphylaxis are estimated to occur in the United States every year. (
  • What Are the Signs & Symptoms of Anaphylaxis? (
  • Anaphylaxis can cause different symptoms at different times. (
  • Call 911 or the local emergency number if you or someone you know develops severe symptoms of anaphylaxis. (
  • Symptoms of anaphylaxis typically start within seconds or minutes of exposure to the food or substance, but on rare occasions there may be a delay of an hour or more. (
  • Someone showing symptoms of anaphylaxis should see their GP as soon as possible and seek referral to an allergy clinic. (
  • Symptoms of anaphylaxis can include difficulty breathing, coughing, and a feeling that something is stuck in the throat. (
  • It is important to know the signs and symptoms of anaphylaxis, because urgent action may be needed. (
  • Call 911 immediately if you think someone's having symptoms of anaphylaxis . (
  • This topic will review the signs and symptoms of anaphylaxis, diagnostic criteria, and common causes and contributory factors. (
  • Idiopathic anaphylaxis-generalized consists of urticaria or angioedema associated with severe respiratory distress, syncope or hypotension, and gastrointestinal symptoms. (
  • If someone has symptoms of anaphylaxis (see below), you should call 999 for an ambulance immediately. (
  • Anaphylaxis typically presents many different symptoms over minutes or hours with an average onset of 5 to 30 minutes if exposure is intravenous and 2 hours if from eating food. (
  • Healthcare personnel who are trained and qualified to recognize the signs and symptoms of anaphylaxis as well as administer intramuscular epinephrine should be available at the vaccination location at all times. (
  • For example, if a person develops itching and swelling confined to the injection site during their post-vaccination observation period, this period may be extended to assess for development of any hypersensitivity signs or symptoms consistent with anaphylaxis (described below). (
  • What are the symptoms of anaphylaxis in a child? (
  • The symptoms of anaphylaxis may look like other health problems. (
  • Symptoms of anaphylaxis include tightness or swelling of the throat, tongue, or uvula. (
  • Symptoms of anaphylaxis can develop within minutes of being exposed to an allergen (substance to which you are allergic). (
  • Anaphylaxis can be diagnosed based on your description of symptoms and a physical examination. (
  • Although these medicines are not helpful in the emergency treatment of life-threatening anaphylaxis, antihistamines can help with itch and hives, and corticosteroids may reduce the risk of symptoms recurring. (
  • Anaphylaxis symptoms in cats may develop following an insect bite, a vaccine, the administration of a drug or contact with an allergen. (
  • If your cat displays the anaphylaxis symptoms for the first time, you will have to help him breathe until you get to an emergency vet clinic. (
  • The immune system responds negatively to these stimuli and produces inflammatory cells that will result in anaphylaxis symptoms. (
  • The same chemicals as with anaphylaxis are released, with the same effects, so the symptoms are treated the same way. (
  • The exact prevalence of anaphylaxis is unknown, because milder reactions may be attributed to asthma attacks or sudden cases of hives, and more serious or fatal episodes might be reported as heart attacks, as the initial symptoms of hives, asthma, and swollen throat can fade quickly. (
  • The symptoms of anaphylaxis may occur within seconds of exposure, or be delayed 15 to 30 minutes and sometimes even an hour or more later, if the allergen is aspirin or other similar drugs. (
  • In most studies, the frequency of signs and symptoms of anaphylaxis is grouped by organ system. (
  • Learn more about the symptoms that occur during anaphylaxis as well as the overall effects on your body. (
  • While they're certainly possible, anaphylaxis can still occur without skin symptoms. (
  • These can occur with or without other symptoms of anaphylaxis. (
  • Learn about the symptoms of anaphylaxis, a severe and potentially life-threatening allergic reaction. (
  • In anaphylaxis, these immune chemicals cause serious skin symptoms, such as hives and swelling, as well as severe breathing problems, such as swelling in the throat, narrowing of the lower airways and wheezing). (
  • The most frequent clinical manifestation in children with food anaphylaxis was gastrointestinal symptoms, whereas cardiovascular symptoms were rare. (
  • Click on the Action Plan below to see the signs and symptoms of anaphylaxis and the emergency steps to take. (
  • Commonly caused by insect bites or stings, medications and food such as peanuts, anaphylaxis shows up with symptoms like tongue swelling, itchy rash, vomiting, shortness of breath, lightheadedness or low blood pressure. (
  • Symptoms of anaphylaxis can manifest within a few minutes or may sometimes take a few hours. (
  • Anaphylaxis is diagnosed on the basis of the development of life-threatening symptoms, after a possible contact with a substance that is likely to trigger an allergy. (
  • For anaphylaxis the symptoms are usually four different organ systems. (
  • While exercise-induced anaphylaxis is not at all common-some experts say it affects about one in a thousand people-symptoms can occur among those who have not previously shown any signs. (
  • With EIA, the word "anaphylaxis" can best be explained as a spectrum of exercise-induced allergic symptoms, all of which should be taken seriously. (
  • Epinephrine usually relieves the most dangerous symptoms of anaphylaxis quickly - including throat swelling , trouble breathing, and low blood pressure . (
  • Anaphylaxis is a severe life-threatening systemic hypersensitivity reaction caused by release of mediators from mast cells and basophils, characterized by cutaneous, respiratory, cardiovascular, or gastrointestinal signs and symptoms. (
  • Anaphylaxis occurs as the result of an allergen response, usually immunoglobulin E-mediated, which leads to mast cell and basophil activation and a combination of dermatologic, respiratory, cardiovascular, gastrointestinal, and neurologic symptoms. (
  • The diagnosis of anaphylaxis is typically made when symptoms occur within one hour of exposure to a specific antigen. (
  • 4 , 5 Patients may arrive at a physician's office remote from an event or with active symptoms, or they may develop anaphylaxis after administration of common treatments used in the clinic. (
  • Due to the rapid and unrelenting progression of symptoms, tragedy strikes when life-saving epinephrine cannot be injected into anaphylaxis-stricken individuals immediately following initiation of an attack. (
  • After an antigen cross-links the IgEs on the membrane of effector cells, a complex intracellular signaling cascade is initiated, which leads cells to release preformed mediators stored in their granules that are responsible for the acute symptoms of anaphylaxis. (
  • Anaphylaxis symptoms can develop quickly, in some cases within minutes or hours after exposure to an allergen. (
  • The most dangerous symptoms of anaphylaxis affect the respiratory system (breathing) and/or cardiovascular system (heart and blood pressure). (
  • Anaphylaxis is an acute systemic (whole body) allergic reaction, which has a collection of symptoms affecting multiple systems in the body. (
  • In anaphylaxis, the chemicals that cause the allergic symptoms (e.g. histamine) are released into the bloodstream. (
  • The symptoms of anaphylaxis usually occur within minutes of exposure to the trigger substance (allergen) but sometimes an hour or so later. (
  • The symptoms can come on very quickly, and soon become severe (NHS 2016, NICE 2011) , so it's worth learning the potential triggers and signs of anaphylaxis to look out for. (
  • Symptoms of anaphylaxis typically occur within 5 to 30 minutes of exposure. (
  • Anaphylaxis occurs after exposure to a particular allergen that the body overreacts to, releasing chemicals that cause allergy symptoms. (
  • Symptoms of anaphylaxis can range from less dangerous allergic symptoms to severe life-threatening symptoms. (
  • The acute treatment of anaphylaxis, pathophysiology, and other related topics are reviewed separately. (
  • the prevention and treatment of anaphylaxis is an important clinical emergency which all healthcare professionals should be able to recognize and manage. (
  • Many of the gaps in the treatment of anaphylaxis included the lack of a practical definition of anaphylaxis as it related to physician. (
  • The diagnosis and treatment of anaphylaxis, fatal anaphylaxis, and other topics related to anaphylaxis are discussed elsewhere. (
  • The primary treatment of anaphylaxis is epinephrine injection into a muscle, intravenous fluids, and positioning the person flat. (
  • Epinephrine, although it is the first-choice treatment of anaphylaxis, often goes unused, even in hospitals and doctors' offices. (
  • In this retrospective study, we review the clinical manifestations and influencing factors of inpatients with anaphylaxis in these 3 well recognized hospitals in Beijing, aiming to help improve early recognition, diagnosis, and treatment of anaphylaxis in clinical practice. (
  • Analysis of these data supports the value of stocking EAIs and of providing continuing education regarding the recognition and proper treatment of anaphylaxis for school personnel. (
  • This course is approved by Allergy UK for anyone who needs training in how and when to use an auto-injector in the treatment of anaphylaxis. (
  • Intramuscular epinephrine (1:1,000 dilution dosed at 0.01 mg per kg [maximal dose of 0.3 mg in children and 0.5 mg in adults]), along with appropriate management of airway, breathing, and circulation, is the first and most important therapeutic option in the treatment of anaphylaxis. (
  • In at least five female case reports of Rocuronium-induced anaphylaxis treated with Sugammedex, a benefit was described, but the effects of other treatments administered concurrently for the treatment of anaphylaxis may have been the main contributor to the noted improvement (5). (
  • Date: Dec 8, 2015 (BOSTON and Hopkinton, Massachusetts): The Wyss Institute for Biologically Inspired Engineering at Harvard University and the KeepSmilin4Abbie Foundation announced today their partnership to advance research and development efforts in the early detection and treatment of anaphylaxis, a severe allergic reaction triggered by exposure to certain foods, materials, medications, and insect bites. (
  • The tragic loss of Abbie compelled her family to establish The KeepSmilin4Abbie Foundation in 2014, with the mission to fund research into technology for the early detection and treatment of anaphylaxis and to increase awareness of this life-threatening complication. (
  • Individuals who are at risk for anaphylaxis or have a history of reactions are typically prescribed an epinephrine autoinjector for IM injection such as EpiPen, EpiPen Jr (Dey L.P.), or Twinject (Sciele Pharma Inc) for the emergency treatment of anaphylaxis. (
  • Epinephrine: the drug of choice for anaphylaxis. (
  • Carrying an epinephrine autoinjector and identification regarding the condition is recommended in people with a history of anaphylaxis. (
  • For self-management of patients at risk of anaphylaxis in community settings, they recommend carrying epinephrine auto-injectors and personalized emergency action plans, as well as follow-up with a physician (ideally an allergy/immunology specialist) to help prevent anaphylaxis recurrences. (
  • ICON: Anaphylaxis describes unmet needs in anaphylaxis, noting that although epinephrine in 1 mg/mL ampules is available worldwide, other essentials, including supplemental oxygen, intravenous fluid resuscitation, and epinephrine auto-injectors are not universally available. (
  • Vaccination locations that anticipate vaccinating large numbers of people (e.g., mass vaccination clinics) should plan adequate staffing and supplies (including epinephrine) for the assessment and management of anaphylaxis. (
  • People with a history of anaphylaxis who carry an epinephrine autoinjector could be reminded to bring it to their vaccination appointment. (
  • It is estimated that almost 600,000 Canadians will experience anaphylaxis in their lifetime and that more than half of the individuals who had anaphylaxis were not equipped with life-saving epinephrine. (
  • The team also observed that the majority (80.2%) of anaphylaxis cases were triggered by food, principally peanut and tree nut, and that children who did not receive epinephrine prior to arrival at the ED were more likely to receive multiple (two or more) doses of epinephrine at the hospital. (
  • This is why your doctor will recommend adrenaline (epinephrine) injections in the case of anaphylaxis. (
  • This EBG recommended that children meeting criteria for anaphylaxis receive prompt intramuscular epinephrine and also receive diphenhydramine and a glucocorticoid. (
  • By using clinical criteria that objectively help the clinician discern if a child is likely having anaphylaxis, early intervention with epinephrine, diphenhydramine, and glucocorticoids increases the likelihood of prompt resolution as well as prevention of late-phase reactions. (
  • Adrenaline (epinephrine) is the recommended first aid drug for anaphylaxis. (
  • If you have a history of anaphylaxis, your doctor should coach you and your family members on how to use self-injectable epinephrine. (
  • One study suggested that patients at risk of food-induced anaphylaxis carry 2 doses of epinephrine. (
  • A 55-year-old woman developed unstable angina following an episode of severe anaphylaxis which was treated with 0.5 mg intramuscular epinephrine (adrenaline). (
  • Four weeks later, she had a second episode of anaphylaxis, and suffered a cardiac arrest after receiving a bolus of intravenous epinephrine. (
  • It highlights the dangers of intravenous epinephrine in treating anaphylaxis outside anaesthetic and intensively monitored settings. (
  • Although epinephrine is the treatment of choice for anaphylaxis, it remains underused. (
  • Severe episodes of anaphylaxis are treated with epinephrine (adrenaline), followed by oral antihistamines and steroids. (
  • Administration of intramuscular epinephrine at the onset of anaphylaxis, before respiratory failure or cardiovascular compromise, is essential. (
  • All patients at risk of recurrent anaphylaxis should be educated about the appropriate use of prescription epinephrine autoinjectors. (
  • Epinephrine (adrenaline) is the medication that is most commonly used to treat anaphylaxis. (
  • As many as 25% of people who have an anaphylactic reaction will experience biphasic anaphylaxis, a recurrence in the hours following the beginning of the reaction, and will require further medical treatment, including additional epinephrine injections. (
  • Epinephrine is the drug of choice and primary therapy in the emergency management of anaphylaxis resulting from insect bites or stings, foods, drugs, latex, or other allergic triggers, and it should be administered immediately. (
  • What does epinephrine do for anaphylaxis? (
  • A person who's familiar with these signs knows that the first way to handle anaphylaxis is to give himself an epinephrine injection. (
  • But the added dose of epinephrine assists your body to calm your anaphylaxis by forcing your blood vessels to constrict. (
  • Contributors "What does epinephrine do for anaphylaxis? (
  • Idiopathic anaphylaxis. (
  • What is idiopathic anaphylaxis? (
  • Idiopathic anaphylaxis is a syndrome of recurrent anaphylaxis for which no consistent triggers can be determined despite an exhaustive search. (
  • If, after a diagnostic investigation, the doctor is unable to identify a trigger for a patient's allergy, the term idiopathic anaphylaxis is used. (
  • Whilst the possibility of an overlooked allergy should always be borne in mind, the name idiopathic anaphylaxis infers that there is no external trigger and that the cause is a temporary increase in the reactivity of the immune system. (
  • Idiopathic anaphylaxis is a prednisone-responsive condition without external cause, but it can coexist with food-, medication-, or exercise-induced anaphylaxis. (
  • Idiopathic anaphylaxis can be classified into frequent (if there are six or more episodes per year or two episodes in the last 2 months) or infrequent (if episodes occur less often). (
  • Idiopathic anaphylaxis-angioedema consists of massive tongue enlargement or severe pharyngeal or laryngeal swelling with urticaria or peripheral angioedema. (
  • The differential diagnosis of idiopathic anaphylaxis is reviewed, and treatment approaches are presented. (
  • This is known as idiopathic anaphylaxis. (
  • The cause remains unknown in 32-50% of cases, referred to as "idiopathic anaphylaxis. (
  • When no etiologic agent has been found despite repeated evaluations, the term idiopathic anaphylaxis is used. (
  • In some cases, a trigger can't be found and this is referred to as idiopathic anaphylaxis. (
  • This study will explore the possible cause of unexplained, or idiopathic, anaphylaxis. (
  • These cases are called idiopathic anaphylaxis. (
  • There is no cure or long-term preventive therapy for patients with recurrent episodes of idiopathic anaphylaxis. (
  • People between 13 and 70 years of age who have idiopathic anaphylaxis, or have anaphylaxis that is caused by specific allergens such as food, venom, or drugs and medications may be eligible for this study. (
  • The most common specific causes of anaphylaxis are venom, drug, and food allergies (i.e. patients with specific anaphylaxis, SA), When a causative factor is not identified in patients are said to have idiopathic anaphylaxis (IA). (
  • Anaphylaxis may be an allergic response that is immunologically mediated, or a non-immunologically mediated response, or idiopathic . (
  • A significant proportion of anaphylaxis is classified as idiopathic, in which there are significant clinical effects but no readily identifiable cause. (
  • Has your allergist mentioned anything about Idiopathic Anaphylaxis? (
  • Two new clinical reports shed light on why some people suffer from recurrent episodes of idiopathic anaphylaxis--a potentially life-threatening condition of unknown cause characterized by a drop in blood pressure, fainting episodes, difficulty in breathing, and wheezing. (
  • While some people suffer anaphylaxis as part of a serious allergic reaction, in two out of three people, anaphylaxis has no known cause and thus the anaphylactic reaction is called idiopathic. (
  • Several years ago, Dean Metcalfe, M.D., chief of the Laboratory of Allergic Diseases at NIAID, Cem Akin, M.D., Ph.D., and their NIAID colleagues decided to find out whether idiopathic anaphylaxis might have a genetic trigger related to that seen in mastocytosis. (
  • So the NIAID team asked, if the Kit mutation could make mast cells grow and cause mastocytosis, and this was associated with anaphylactic reactions, could the same mutation predispose mast cells to release chemicals responsible for idiopathic anaphylaxis? (
  • In a two-year study conducted at the NIH Clinical Center, the researchers examined 48 patients diagnosed with mastocytosis with or without associated anaphylaxis, 12 patients with idiopathic anaphylaxis, and 12 patients with neither disease. (
  • Within the group of 12 patients who had idiopathic anaphylaxis, five were found with evidence of a disorder in a line of mast cells (clonal mast cell disorder). (
  • The findings demonstrate that some patients with idiopathic anaphylaxis have an aberrant population of mast cells with mutated Kit. (
  • We believe the mutation may be predisposing people to idiopathic anaphylaxis," says Dr. Metcalfe. (
  • Our findings suggest that in patients with idiopathic anaphylaxis as well as in people with severe allergies, we should look for critical genetic mutations that may change the way a mast cell reacts. (
  • The study that appears in an early online edition in Blood describes the presence of an abnormal mast cell population in a subset of patients with idiopathic anaphylaxis. (
  • Pollen and other inhaled allergens rarely cause anaphylaxis. (
  • Prescribed drugs: Any medication taken for years may suddenly cause anaphylaxis. (
  • [2008 Sept] HPV vaccine shows higher rate of anaphylaxis: study The human papilomavirus (HPV) vaccine is up to 20 times more likely than other school-based vaccines to cause anaphylaxis, according to a study released Monday. (
  • Most commonly known medicines that may cause anaphylaxis are penicillin, aspirin and NSAIDs. (
  • Stings from insects like wasps, bees, fire ants, and kissing bugs may cause anaphylaxis in people who are vulnerable. (
  • Many substances can cause anaphylaxis. (
  • While succinylcholine, a nonsteroidal NMBA, was the most common NMBA to cause anaphylaxis 10 years ago, more recent studies indicate that Rocuronium, a steroidal NBMA, is equal to succinylcholine as NMBAs causing anaphylaxis, about 1: 2000 to 1: 2500 exposures (3). (
  • Medications can cause anaphylaxis, particularly drugs in the penicillin family. (
  • Aimee suffers from multiple food allergies which could cause anaphylaxis. (
  • Physical factors such as exercise (known as exercise-induced anaphylaxis) or temperature (either hot or cold) may also act as triggers through their direct effects on mast cells. (
  • February 18/ Obesity, Fitness & Wellness Week -- "Food-dependent exercise-induced anaphylaxis (FDEIA) due to soybeans is a rare disorder. (
  • Adachi and colleagues published their study in Clinical and Experimental Allergy ("Soybean beta-conglycinin as the main allergen in a patient with food-dependent exercise-induced anaphylaxis by tofu: food processing alters pepsin resistance. (
  • These images are a random sampling from a Bing search on the term "Exercise-Induced Anaphylaxis. (
  • A younger age and eczema were more frequent among children with food-dependent anaphylaxis, whereas an older age together with urticaria-angioedema were common among those with exercise-induced anaphylaxis. (
  • Food-induced anaphylaxis often occurs in younger children with a severe food allergy, whereas exercise-induced anaphylaxis occurs more often in older children with a history of urticaria-angioedema. (
  • Exercise Induced Anaphylaxis: Can You Be Allergic to Exercise? (
  • Turns out, Susan experienced a rare, total-body allergic reaction called exercise-induced anaphylaxis (EIA), which is brought on by exercise or exercise plus additional factors, such as certain food(s) ingested around the time of exercise (for Susan, it was the chopped-up celery in her sandwich). (
  • In defining exercise-induced anaphylaxis, it's important to clarify that it isn't actually a true allergy to exercise, which, of course, sounds like the world's greatest excuse for staying sedentary. (
  • The term exercise-induced anaphylaxis is more accurate and less sensational," says Smart. (
  • With regard to exercise-induced anaphylaxis unrelated to co-ingestion of foods, there are notions that exercise in the pollen season, high heat, extreme cold, high humidity or more extreme exercise may be a factor," says Scott H. Sicherer, M.D., a professor of pediatrics at Jaffe Food Allergy Institute, Mount Sinai School of Medicine in New York. (
  • Also, there are descriptions of people having exercise-induced anaphylaxis from mild exercise (such as raking leaves). (
  • Another condition that may affect exercisers is cholinergic urticaria, which some experts see as either a milder presentation of exercise-induced anaphylaxis (EIA) or a separate entity altogether. (
  • It is likely more common than exercise-induced anaphylaxis. (
  • A novel wheat gliadin is the cause of exercise-induced anaphylaxis. (
  • The best defined example is food-dependent exercise induced anaphylaxis. (
  • Many cases of exercise induced anaphylaxis can be related to a food allergen ingested before the reaction. (
  • Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen . (
  • Anaphylaxis can occur in response to any allergen. (
  • Tests for the allergen that caused anaphylaxis (if the cause is not obvious) may be done after treatment. (
  • Anaphylaxis is an acute systemic (whole body) type of allergic reaction which occurs when a person has become sensitized to a certain substance or allergen and is again exposed to the allergen. (
