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.

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.

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)

Symptoms of anaphylaxis include:

1. Swelling of the face, lips, tongue, and throat
2. Difficulty breathing or swallowing
3. Abdominal cramps
4. Nausea and vomiting
5. Rapid heartbeat
6. Feeling of impending doom or loss of consciousness

Anaphylaxis is diagnosed based on a combination of symptoms, medical history, and physical examination. Treatment for anaphylaxis typically involves administering epinephrine (adrenaline) via an auto-injector, such as an EpiPen or Auvi-Q. Additional treatments may include antihistamines, corticosteroids, and oxygen therapy.

Prevention of anaphylaxis involves avoiding known allergens and being prepared to treat a reaction if it occurs. If you have a history of anaphylaxis, it is important to carry an EpiPen or other emergency medication with you at all times. Wearing a medical alert bracelet or necklace can also help to notify others of your allergy and the need for emergency treatment.

In severe cases, anaphylaxis can lead to unconsciousness, seizures, and even death. Prompt treatment is essential to prevent these complications and ensure a full recovery.

There are several types of food hypersensitivity, including:

1. Food Allergy: An immune system reaction to a specific food that can cause symptoms ranging from mild hives to life-threatening anaphylaxis. Common food allergies include reactions to peanuts, tree nuts, fish, shellfish, milk, eggs, wheat, and soy.
2. Non-Allergic Food Hypersensitivity: Also known as non-IgE-mediated food hypersensitivity, this type of reaction does not involve the immune system. Symptoms can include bloating, abdominal pain, diarrhea, and headaches. Common culprits include gluten, dairy, and high-FODMAP foods.
3. Food Intolerance: A condition where the body cannot properly digest or process a specific food. Symptoms can include bloating, abdominal pain, diarrhea, and gas. Common food intolerances include lactose intolerance, fructose malabsorption, and celiac disease.
4. Food Aversion: An emotional response to a specific food that can cause avoidance or dislike of the food. This is not an allergic or physiological reaction but rather a psychological one.

The diagnosis of food hypersensitivity typically involves a thorough medical history, physical examination, and diagnostic tests such as skin prick testing or blood tests. Treatment options for food hypersensitivity depend on the type and severity of the reaction and may include avoidance of the offending food, medication, or immunotherapy.

There are several different types of drug hypersensitivity reactions, including:

1. Maculopapular exanthema (MPE): This is a type of allergic reaction that causes a red, itchy rash to appear on the skin. It can be caused by a variety of medications, including antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs).
2. Exfoliative dermatitis: This is a more severe form of MPE that can cause widespread scaling and peeling of the skin. It is often associated with reactions to antibiotics and other medications.
3. Stevens-Johnson syndrome (SJS): This is a rare but potentially life-threatening condition that can be caused by certain medications, including antibiotics and NSAIDs. SJS can cause blisters to form on the skin and mucous membranes, as well as fever and fatigue.
4. Toxic epidermal necrolysis (TEN): This is a severe and potentially life-threatening condition that can be caused by certain medications, including antibiotics and NSAIDs. TEN can cause widespread peeling of the skin, as well as fever and fatigue.
5. Anaphylaxis: This is a severe allergic reaction that can be caused by a variety of medications, including antibiotics and NSAIDs. It can cause symptoms such as hives, itching, swelling, and difficulty breathing.

Drug hypersensitivity reactions can be diagnosed through a combination of physical examination, medical history, and laboratory tests. Treatment typically involves discontinuing the medication that is causing the reaction, as well as providing supportive care to manage symptoms such as fever, itching, and pain. In severe cases, hospitalization may be necessary to monitor and treat the reaction.

Prevention of drug hypersensitivity reactions can be challenging, but there are several strategies that can help reduce the risk. These include:

1. Gradual dose escalation: When starting a new medication, it is important to gradually increase the dose over time to allow the body to adjust.
2. Monitoring for signs of a reaction: Patients should be monitored closely for signs of a reaction, such as hives, itching, or difficulty breathing.
3. Avoiding certain medications: In some cases, it may be necessary to avoid certain medications that are known to cause hypersensitivity reactions.
4. Skin testing: Skin testing can be used to determine whether a patient is allergic to a particular medication before starting treatment.
5. Desensitization: In some cases, desensitization therapy may be used to gradually expose the patient to the medication that is causing the reaction, with the goal of reducing the risk of an adverse event.

Insects such as mosquitoes, wasps, bees, and hornets are common culprits of bites and stings that cause minor to severe reactions in humans. These reactions may cause pain, redness, swelling, itching, and burning sensations at the site of the bite or sting.

Most insect bites and stings can be treated with over-the-counter medications such as antihistamines, hydrocortisone creams, or calamine lotion. Severe allergic reactions may require medical attention and epinephrine injections to prevent anaphylaxis.

Types of Wheat Hypersensitivity:

1. Celiac Disease: This is an autoimmune disorder that causes the immune system to attack the small intestine when gluten, a protein found in wheat, barley, and rye, is consumed. Symptoms include abdominal pain, diarrhea, fatigue, and weight loss.
2. Non-Celiac Gluten Sensitivity (NCGS): This condition is similar to celiac disease but does not involve an autoimmune response or intestinal damage. Symptoms can include bloating, abdominal pain, diarrhea, and fatigue.
3. Wheat Allergy: An immune system reaction to one or more proteins found in wheat, which can cause symptoms such as hives, itching, swelling, stomach cramps, diarrhea, and difficulty breathing. In severe cases, anaphylaxis can occur, which is a life-threatening reaction that requires immediate medical attention.

Symptoms of Wheat Hypersensitivity:

1. Gastrointestinal symptoms: Abdominal pain, bloating, diarrhea, nausea, and vomiting are common gastrointestinal symptoms of wheat hypersensitivity.
2. Skin symptoms: Hives, itching, and skin rashes can occur as a result of an allergic reaction to wheat.
3. Respiratory symptoms: Wheat allergy can cause respiratory symptoms such as coughing, sneezing, runny nose, and difficulty breathing.
4. Cardiovascular symptoms: Some individuals with wheat hypersensitivity may experience cardiovascular symptoms such as a rapid heartbeat, low blood pressure, and collapse.
5. Neurological symptoms: In rare cases, wheat allergy can cause neurological symptoms such as headaches, fatigue, and difficulty concentrating.

Diagnosis of Wheat Hypersensitivity:

1. Medical history: A thorough medical history is essential to diagnose wheat hypersensitivity. Symptoms, dietary habits, and any known allergies or medical conditions should be taken into account.
2. Physical examination: A physical examination can reveal signs of an allergic reaction such as hives, itching, swelling, and difficulty breathing.
3. Allergy testing: Skin prick testing or blood tests can confirm the presence of IgE antibodies against wheat proteins, which is a hallmark of wheat allergy.
4. Elimination diet: An elimination diet involves removing wheat from the diet for a period of time and then reintroducing it to assess for any adverse reactions.
5. Food challenge: A food challenge involves giving the individual a small amount of wheat in a controlled medical setting to assess for any adverse reactions.

Treatment and Management of Wheat Hypersensitivity:

1. Avoidance: The most effective treatment for wheat hypersensitivity is avoidance of wheat-containing foods.
2. Antihistamines: Antihistamines can help alleviate symptoms such as hives, itching, and difficulty breathing.
3. Corticosteroids: Corticosteroids can reduce inflammation and swelling associated with an allergic reaction.
4. Epinephrine injection: In severe cases of anaphylaxis, epinephrine injection may be necessary to stabilize the individual.
5. Allergen immunotherapy: Sublingual immunotherapy (SLIT) or oral immunotherapy (OIT) can help desensitize the individual to wheat proteins over time, reducing symptoms and the risk of anaphylaxis.
6. Nutritional counseling: Individuals with wheat hypersensitivity may require nutritional counseling to ensure they are getting enough essential nutrients while avoiding wheat-containing foods.
7. Monitoring: Regular monitoring of symptoms and the effectiveness of treatment is crucial to managing wheat hypersensitivity.

It's important to note that individuals with wheat hypersensitivity should carry an EpiPen or other epinephrine injectors with them at all times in case of an emergency. Additionally, they should be aware of the signs and symptoms of anaphylaxis and seek medical attention immediately if they experience any of these symptoms.

Peanut hypersensitivity occurs when the immune system mistakenly identifies peanut proteins as harmful and attacks them, releasing histamine and other chemicals that cause allergic symptoms. The symptoms of peanut hypersensitivity can range from mild to severe and include hives, itching, swelling, stomach cramps, diarrhea, vomiting, difficulty breathing, and a drop in blood pressure.

The diagnosis of peanut hypersensitivity is typically made through a combination of medical history, physical examination, and laboratory tests such as skin prick testing or blood tests. The treatment for peanut hypersensitivity involves avoiding peanuts altogether and being prepared to treat an allergic reaction with epinephrine (adrenaline) if it occurs. In severe cases, hospitalization may be necessary to monitor and treat the allergic reaction.

It is important for individuals with peanut hypersensitivity to carry an EpiPen or other emergency medication with them at all times in case of an accidental exposure to peanuts. It is also important to avoid cross-contamination with peanuts in food and other environments, as even trace amounts of peanuts can cause a severe allergic reaction. With proper treatment and precautions, individuals with peanut hypersensitivity can lead normal and healthy lives.

The symptoms of urticaria can vary in severity and may include:

* Appearance of hives or wheals on the skin, often in a patterned or widespread distribution
* Itching or burning sensations on the skin
* Redness, swelling, or warmth of the affected area
* In some cases, angioedema (swelling of the deeper layers of skin)

Urticaria can be caused by a variety of factors, including:

* Allergies to foods, drugs, or insect bites
* Exposure to environmental allergens such as pollen, dust mites, or animal dander
* Infections, such as colds or flu
* Physical stimuli, such as pressure, cold, or heat
* Certain medications, such as antibiotics or nonsteroidal anti-inflammatory drugs (NSAIDs)
* Hormonal changes, such as those that occur during pregnancy or menstruation

Urticaria can be diagnosed through a physical examination and medical history, and may require further testing to determine the underlying cause. Treatment for urticaria typically involves avoiding triggers, using antihistamines or corticosteroids to reduce symptoms, and addressing any underlying conditions that may be contributing to the condition. In severe cases, hospitalization may be necessary to manage the symptoms and prevent complications.

Synonyms: Bronchial Constriction, Airway Spasm, Reversible Airway Obstruction.

Antonyms: Bronchodilation, Relaxation of Bronchial Muscles.

Example Sentences:

1. The patient experienced bronchial spasms during the asthma attack and was treated with an inhaler.
2. The bronchial spasm caused by the allergic reaction was relieved by administering epinephrine.

There are several types of hypersensitivity reactions, including:

1. Type I hypersensitivity: This is also known as immediate hypersensitivity and occurs within minutes to hours after exposure to the allergen. It is characterized by the release of histamine and other chemical mediators from immune cells, leading to symptoms such as hives, itching, swelling, and difficulty breathing. Examples of Type I hypersensitivity reactions include allergies to pollen, dust mites, or certain foods.
2. Type II hypersensitivity: This is also known as cytotoxic hypersensitivity and occurs within days to weeks after exposure to the allergen. It is characterized by the immune system producing antibodies against specific proteins on the surface of cells, leading to their destruction. Examples of Type II hypersensitivity reactions include blood transfusion reactions and serum sickness.
3. Type III hypersensitivity: This is also known as immune complex hypersensitivity and occurs when antigens bind to immune complexes, leading to the formation of deposits in tissues. Examples of Type III hypersensitivity reactions include rheumatoid arthritis and systemic lupus erythematosus.
4. Type IV hypersensitivity: This is also known as delayed-type hypersensitivity and occurs within weeks to months after exposure to the allergen. It is characterized by the activation of T cells, leading to inflammation and tissue damage. Examples of Type IV hypersensitivity reactions include contact dermatitis and toxic epidermal necrolysis.

The diagnosis of hypersensitivity often involves a combination of medical history, physical examination, laboratory tests, and elimination diets or challenges. Treatment depends on the specific type of hypersensitivity reaction and may include avoidance of the allergen, medications such as antihistamines or corticosteroids, and immunomodulatory therapy.

People who are allergic to latex may experience the following symptoms:

* Hives or itchy skin
* Swelling of the face, lips, tongue, or throat
* Difficulty breathing or swallowing
* Abdominal cramps
* Diarrhea
* Anaphylaxis (a severe, life-threatening allergic reaction)

Latex hypersensitivity can be triggered by exposure to latex gloves, medical equipment, or other products containing latex. The allergy is more common in healthcare workers and individuals who have undergone multiple surgical procedures.

There is no cure for latex hypersensitivity, but avoiding exposure to latex can help manage the symptoms. Some individuals may also be prescribed medication to reduce inflammation and prevent future reactions. In severe cases, immunotherapy or desensitization treatment may be recommended to increase tolerance to latex.

It is essential for healthcare providers to be aware of this allergy and take necessary precautions when treating patients with latex hypersensitivity. This includes using non-latex gloves and medical equipment, thoroughly cleaning and disinfecting surfaces, and being prepared to treat anaphylaxis if it occurs.

Early diagnosis and proper management of latex hypersensitivity can improve the quality of life for individuals affected by this allergy.

Some of the key features of immediate hypersensitivity include:

1. Rapid onset of symptoms: Symptoms typically occur within minutes to hours of exposure to the allergen.
2. IgE antibodies: Immediate hypersensitivity is caused by the binding of IgE antibodies to surface receptors on mast cells and basophils.
3. Mast cell and basophil activation: The activation of mast cells and basophils leads to the release of histamine and other chemical mediators that cause symptoms.
4. Anaphylaxis: Immediate hypersensitivity can progress to anaphylaxis, a life-threatening allergic reaction that requires immediate medical attention.
5. Specificity: Immediate hypersensitivity is specific to a particular allergen and does not occur with other allergens.
6. Cross-reactivity: There may be cross-reactivity between different allergens, leading to similar symptoms.
7. Prevention: Avoidance of the allergen is the primary prevention strategy for immediate hypersensitivity. Medications such as antihistamines and epinephrine can also be used to treat symptoms.

Acute angioedema is usually triggered by an allergic reaction or exposure to certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), blood pressure medications, or antibiotics. It can also be caused by infections, insect bites, and other environmental triggers.

Chronic angioedema, on the other hand, is a more persistent form of the condition that can last for weeks, months, or even years. It is often associated with conditions such as hereditary angioedema (HAE), which is caused by a genetic defect that affects the production of a protein called C1 esterase inhibitor.

The symptoms of angioedema can vary depending on the location and severity of the swelling, but they typically include:

* Swelling in the face, hands, feet, or other parts of the body
* Redness and warmth of the affected area
* Pain or discomfort
* Difficulty breathing or swallowing (in severe cases)

There is no cure for angioedema, but there are several treatments available to help manage the symptoms. These may include:

* Antihistamines or corticosteroids to reduce inflammation and relieve itching
* Ice packs or cool compresses to reduce swelling
* Compression stockings or bandages to prevent fluid buildup
* Pain relief medications, such as ibuprofen or acetaminophen, to manage discomfort

In severe cases of angioedema, hospitalization may be necessary to provide more intensive treatment and monitoring. In some cases, injectable medications such as epinephrine or corticosteroids may be administered to help reduce swelling and prevent complications.

Overall, angioedema is a serious condition that requires prompt medical attention to manage symptoms and prevent complications. If you suspect you or someone else may have angioedema, it is important to seek medical help right away.

1. Causes: The immune system mistakenly identifies proteins in nuts as harmful, triggering the release of histamine and other chemicals that cause allergic symptoms.
2. Symptoms: Mild symptoms may include hives, itching, swelling, stomach cramps, diarrhea, and difficulty breathing. Severe reactions can lead to anaphylaxis, a life-threatening condition that requires immediate medical attention.
3. Common nut allergens: The most common allergenic proteins in nuts are from tree nuts (such as walnuts, almonds, and pecans) and peanuts.
4. Prevalence: Nut hypersensitivity is relatively rare but can be severe. According to Food Allergy Research & Education (FARE), around 1% of adults and 1.5% of children in the United States have a tree nut allergy, while peanut allergies affect about 1% of the population.
5. Diagnosis: A healthcare professional will typically conduct a physical examination, take a medical history, and perform diagnostic tests like skin prick testing or blood tests to confirm the presence of an immunoglobulin E (IgE) antibody response to nuts.
6. Treatment and management: The primary treatment for nut hypersensitivity is avoidance of nuts and products containing nuts. In severe cases, epinephrine injections may be necessary to treat anaphylaxis. Antihistamines, corticosteroids, and other medications may also be prescribed to manage symptoms.
7. Prognosis: While there is currently no cure for nut hypersensitivity, some individuals may outgrow their allergy over time. However, it's essential to maintain a strict avoidance diet to prevent accidental exposures and potentially life-threatening reactions.
8. Coexistence with other allergies: Nut allergies can coexist with other food allergies, such as peanut or soy allergies, or with non-food allergies like asthma or eczema. This increases the complexity of managing the condition and requires a comprehensive treatment plan.
9. Impact on quality of life: Nut hypersensitivity can have a significant impact on an individual's quality of life, affecting their social, emotional, and physical well-being. It can also limit their dietary choices and create anxiety about potential exposures.
10. Current research and future outlook: Ongoing research into the immunological mechanisms of nut allergies may lead to the development of novel treatments or prevention strategies. Additionally, there is hope for the development of a nut-specific immunotherapy, which could help desensitize individuals with nut allergies and potentially cure the condition.

  • 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. (cdc.gov)
  • 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 potential management of anaphylaxis. (cdc.gov)
  • People with a history of anaphylaxis who carry an epinephrine autoinjector could be reminded to bring it to their vaccination appointment. (cdc.gov)
  • Those who have a high risk of anaphylaxis often carry an autoinjector containing epinephrine (adrenaline). (allergy-testing-and-treatment.com)
  • While such a strategy would likely not replace life-saving, emergency epinephrine when anaphylaxis occurs, therapies targeting Tfh13 cells might prevent the onset of anaphylaxis when an allergic person is exposed to an allergen. (nih.gov)
  • Severe episodes of anaphylaxis are treated with epinephrine (adrenaline), followed by oral antihistamines and steroids. (nih.gov)
  • 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. (nih.gov)
  • 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. (nih.gov)
  • 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. (nih.gov)
  • 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? (nih.gov)
  • 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. (nih.gov)
  • 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). (nih.gov)
  • The findings demonstrate that some patients with idiopathic anaphylaxis have an aberrant population of mast cells with mutated Kit. (nih.gov)
  • We believe the mutation may be predisposing people to idiopathic anaphylaxis," says Dr. Metcalfe. (nih.gov)
  • 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. (nih.gov)
  • 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. (nih.gov)
  • Cases in which no trigger can be identified are referred to as idiopathic anaphylaxis . (allergy-testing-and-treatment.com)
  • This study will explore the possible cause of unexplained, or idiopathic, anaphylaxis. (nih.gov)
  • These cases are called idiopathic anaphylaxis. (nih.gov)
