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 ...
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 ...
CAI urges MPs to Advance Anaphylaxis 5-Point Action Policy. Canadian Anaphylaxis Initiative urges action at Federal level. June 17, 2013 - OTTAWA - A volunteer network of families celebrate the recent historic Parliamentary vote and, at the same time, urge MPs to push for action that can improve the lives of Canadians coping with the medical condition anaphylaxis. The Canadian Anaphylaxis Initiative (CAI) would like to have the Government follow-up the House of Commons unanimous vote for greater anaphylaxis awareness with a coordinated plan of action led by Health Canada. On May 22, the House of Commons wholly supported a motion to raise awareness of anaphylaxis. Motion M-230 calls for the government to take "the appropriate measures necessary to ensure these Canadians are able to maintain a high quality of life." Cindy Paskey, a CAI founder, says, "We are all encouraged that the federal government has anaphylaxis on its radar screen. Our group has spent years with MPs Dean Allison, Rick ...
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 ...

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, ...
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. ...
TY - JOUR. T1 - Factors associated with repeated use of epinephrine for the treatment of anaphylaxis. AU - Manivannan, Veena. AU - Campbell, Ronna L.. AU - Bellolio, Fernanda. AU - Stead, Latha G.. AU - Li, James T C. AU - Decker, Wyatt W.. PY - 2009/11. Y1 - 2009/11. N2 - Background: Studies looking at the use of repeated doses of epinephrine in patients experiencing anaphylaxis are limited. 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 www.Anaphylaxis101.com 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?

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?

Although many people take bee pollen as a health supplement, it can cause severe anaphylactic reactions. However, most people are unaware of the risks, states an article published in CMAJ (Canadian Medical Association Journal).
Most (57-78%) of the recorded anaphylactic reactions in children occur at home and, second, in school or during school activities (5-22%). Children with food allergy are at the highest risk for death, especially if they also suffer from asthma, as most of the deaths attributed to anaphylaxis are due to severe unresponsive bronchospasm. There is a need of education of families and schools on how to prevent and manage anaphylaxis. The preparedness of schools is very variable across Europe, due to various health and education systems. In a national survey of school nurses in UK, more than 80% felt confident in the management of respiratory distress, airway obstruction and anaphylaxis, 77% had adrenaline and albuterol available, and 13% had oxygen. The situation in most countries of Europe is much worse than this, as school nurses are not present in many schools. The education for both families and schools must be directed to provide skills on how to identify severe reactions in children at risk, ...
At Odense University Hospital, nurses take part in a simulation training in critical patient care for younger doctors. One of the scenarios used is anaphylactic shock after the application of IV antibiotics. 49 out of 50 nurses realized within the first two minutes, that the simulation patient suffered from anaphylaxis. 48 out of 50 nurses stopped the IV with the antibiotic. Often, oxygen and IV NaCl was administered, and thereafter the doctor, who was five minutes away was called. Only two out of 50 nurses primarily injected adrenalin according to the hospital guideline.. Because of this, in 48 out of 50 cases adrenalin was given after more than five minutes. According to Pumphrey (2000), the median for a deadly anaphylactic reaction after the IV administration of medication is five minutes. Adrenalin is according to EAACI Guidelines 2014 and ERC Guidelines 2010 the primary treatment for anaphylactic shock and the only treatment that is lifesaving in such a situation. ...

A 4 month old infant presents to your hospital with a history of becoming unwell with difficulty in breathing after being given a different cows milk formula. She had previous devevloped urticaria with some porriage. This case incorporates a few common clinical challenges: how to recognise anaphylaxis in infants, identifying the responsible allergen and determining the most appropriate anaphylaxis management plan. Recognition of anaphylaxis in infancy: anaphylaxis can be difficult to recognise in infants and readily confused with other presentations (Simons 2007). Finding the responsible allergen: in this case, there is seemingly no contact with a new food. The challenge is that food manufacturers use multiple ingrediates in processed food so that a cows milk formula will not only include cows milk (Roberts 2008). Additionally other non food allergens should be considered, examples are latex and insect stings. Some food may only behave as allergens with a co-factor such as exercise. Skin prick testing

Background: Previous US population-based epidemiologic studies of anaphylactic deaths have been limited by small populations and/or few deaths. The objective of this study was to determine the 10-year incidence of death from anaphylaxis in Florida and its descriptive epidemiology.. Methods: Patients who died from anaphylaxis from 1996 to 2005 were identified from ICD-9 and ICD-10 codes on death certificates statewide. Age, race and gender-specific anaphylactic death rates were calculated.. Results: There were 89 deaths among Florida residents. The individuals with autopsy confirmed diagnoses, and those with clinical diagnoses only, did not differ with regard to race, anaphylactic triggers or the clinical variables of lung and heart disease. Annual death rate for anaphylaxis in Florida was 5.02/10 000 000. The relative risk of death from anaphylaxis was 14.09 for individuals ≥65 years old (P = 0.0000002) and 6.38 for individuals 35-64 years old (P = 0.0019) compared with those who were 5-14 ...
We were disappointed that a number of myths about Group B Strep screening were reiterated in the article "Streptococcus B in pregnancy: to screen or not to screen?"1. Dr McCartney is concerned that alongside the very apparent potential benefits of screening, the potential limitations and harms are also raised. Clearly any decision about screening should consider both. However, there are some statements in the article with which we take issue:. 1. Risk of fatal anaphylaxis "The risks of antibiotic use include anaphylaxis, which is thought to be fatal in one in 10,000 women treated" is an unreferenced statement taken from the UK National Screening Committees 2008 review of antenatal screening for group B Streptococcus2. Potentially fatal anaphylaxis is clearly a risk but extremely rare. Law et al3 reported that 1.8 million women in the US will have been given benzylpenicillin (or ampicillin) between 1997 and 2001 and no deaths from anaphylaxis were reported. Furthermore, a review of UK data by ...
anaphylaxis must take into account the sensitivity of the recipient, the dose and character of the diagnostic or therapeutic agent, and the effect of the route of administration on the rate of absorption. Beta blockers are relatively contraindicated in persons at risk for anaphylactic reactions, especially those sensitive to Hymenoptera venom or those undergoing immunotherapy for respiratory system allergy. If there is a definite history of a past anaphylactic reaction to a medication, even though mild, it is advisable to select a structurally unrelated agent. A knowledge of cross-reactivity among agents is critical since, for example, cephalosporins have a cross-reactive ring structure with the penicillins. When skin testing, a prick or scratch skin test should precede an intradermal test, since the latter has a higher risk of causing anaphylaxis. These tests should be performed before the administration of certain materials that are likely to elicit anaphylactic reactions, such as allergenic ...
Allergy: Anaphylaxis. Anaphylaxis is a rare but severe allergic reaction that can occur after exposure to an allergy-causing substance. If you have a history of allergies or a family history of anaphylactic reactions, you may be at higher risk. Causes of anaphylaxis include certain medications, latex, insect bites and stings, and foods such as peanuts, shellfish, and dairy products.
Among the most common causes of anaphylactic shock is penicillin (1 response to 5000 exposures), insect venom and application of radiocontrast agents. Anaphylaxis is an acute, life-threatening syndrome with multisystemic manifestations. Anaphylactic...
The incidence of anaphylaxis in children and adolescents turns around 10/100 000 children per year. In this age group food allergy is the most important cause of anaphylaxis, followed by reactions to medication, latex and insect stings. Most children experiencing anaphylaxis are atopic. However, anaphylaxis due to insect stings is not correlated with atopy. Dermatological and respiratory symptoms occur most frequently, whereas one out of four patients has gastrointestinal or cardiovascular symptoms. The recurrence risk of anaphylaxis is estimated at 1/12 patients per year. In our own patient group, we recorded 39 anaphylactic episodes in 32 patients in 18 months. Mean patient age was 4 year. Food was the cause of anaphylaxis in 28/39 episodes ...
In contrast to the standardized schemes of SIT for pollen-induced and pollen-related allergies mentioned previously, in certain food allergies, individually adapted schemes have to be applied. Especially in protein allergy, like CM allergy in young children with atopic eczema, the variable response of each patient to the different allergen components may influence the potential clinical outcome. Therefore, the mode of application of ASIT is a very delicate matter and not seldom has to be interrupted and discontinued because of the occurrence of uncontrolled side effects that might indicate possible differences in the mechanism, which are known for classical immunotherapy with airway allergies. With respect to the fact that prolonged elimination diets are not without risks, such as deficiency and growth retardation,[37] eating disorders, impaired psychosocial development,[38, 39] or even severe anaphylactic reactions,[40] SIT has become a successfully used alternative, the major aim of which is ...
The transition to adulthood can be particularly challenging for young people with severe allergies, who must learn to balance personal safety with independent living. Information and support for young people and their families are crucial to successfully managing this transition. We sought to: gather insights into the impact of severe allergies on the lives of young people; explore where young people go for information about anaphylaxis and what information they want and need; identify areas where further support is needed. An online questionnaire survey of young people aged 15-25 years with severe allergies in the United Kingdom (UK) was conducted on behalf of the Anaphylaxis Campaign, the main patient support organisation. Participants were recruited mainly from the Anaphylaxis Campaign membership database and also via allergy clinics and social media. The study was funded by the Anaphylaxis Campaigns In Memoriam Fund. A total of 520 young people responded to the survey. The majority had lived with
A new study led by AllerGen researcher Dr. Moshe Ben-Shoshan suggests that treatment guidelines for managing anaphylaxis in children should be reassessed, and shows that pre-hospital treatment with epinephrine has the greatest protective effect against uncontrolled allergic reactions.. The research, published in the Journal of Allergy and Clinical Immunology: In Practice, involved nearly 3,500 patients, making it the largest study to assess the clinical outcomes of pre-hospital treatment of anaphylaxis. Of the patients examined, 80% were children aged one to 17 years. The patient data derived from AllerGens nationwide Cross-Canada Anaphylaxis REgistry (C-CARE) project, involving nine emergency departments in five provinces.. "We found that steroids, which are part of the treatment plan for managing anaphylaxis, can have a negative effect on patient outcomes," says Dr. Ben-Shoshan.. "Our study also shows that the use of an epinephrine autoinjector in the pre-hospital setting has a significant ...
