Patients experiencing anaphylactic shock should be hospitalized for an observational period of 48 to 72 hours.16 Organs involved in the initial reaction may quickly deteriorate and should be monitored closely. These organ systems can experience a secondary or biphasic response.Anaphylaxis can affect multiple body systems and symptoms are generally broken down into four main areas of manifestation: Respiratory, skin, cardiovascular and gastrointestinal.Risk factors for severe anaphylaxis due to immunotherapy include poorly controlled asthma, concurrent use of beta-blockers, high allergen dose, errors in administration, and lack of a sufficient observation period following the injection.

Epidemiology of anaphylaxis. Curr Opin Allergy Clin Immunol. 2008 Aug. 8(4):316-20. [Medline]. Anaphylaxis is primarily a clinical diagnosis. The first priority in the physical examination should be to assess the patient’s airway, breathing, circulation, and adequacy of mentation (eg, alertness, orientation, coherence of thought).Diagnosis of anaphylaxis is based on a comprehensive clinical history of the patient and physical examination as there is no one, single diagnostic test or procedure that can identify anaphylaxis. Some tests which are available to help with the diagnosis of anaphylaxis include:

  6. Anaphylaxis is an acute, potentially fatal, multiorgan system reaction caused by the release of chemical mediators from mast cells and basophils. [1, 2] The classic form involves prior sensitization to an allergen with later re-exposure, producing symptoms via an immunologic mechanism. (See Pathophysiology and Etiology.)

Vasodilation, hypotension, and flushing are mediated by both H1 receptors and H1 receptors. H1 receptors alone mediate coronary artery vasoconstriction, tachycardia, vascular permeability, pruritus, bronchospasm, and rhinorrhea. H2 receptors increase atrial and ventricular contractility, atrial chronotropy, and coronary artery vasodilation. H3 receptors in experimental models of canine anaphylaxis appear to influence cardiovascular responses to norepinephrine. The importance of H3 receptors in humans is unknown.

Hornets defend their nests aggressively and have much more painful stings than either wasps or bees due to the amount of acetylcholine in their venom. Wasp and hornet stings contain the same proteins associated with bee venom with the exception of melittin. Bites and stings may produce a toxic envenomation response.

If the patient presents in respiratory distress, it may be necessary to secure an airway. An endotracheal tube may be placed for patients with laryngeal swelling. If an endotracheal tube is not feasible because of swelling, a temporary tracheostomy tube may be placed surgically. Albuterol (a β-agonist) may help cause bronchodilation and decrease bronchospasm.Emergency-kit: Patients should carry an emergency kit with them at all times and know how and when to administer various medications, including H1-antihistamine, corticosteroids, and epinephrine. Pretreatment with antihistamines or corticosteroids and use of low-molecular-weight (LMW) contrast agents lead to lower rates of anaphylactoid reactions to IV radiocontrast media (approximately 0.5%). Consider these measures for patients who have prior history of reaction, since rate of recurrence is estimated at 17-60%. Some institutions use only LMW agents. Personnel, medications, and equipment needed for treatment of allergic reactions always should be available when these agents are administered. Obtain consent before administration.

Clinical signs sometimes subside and acutely reappear after several hours. These are known as biphasic reactions and can increase mortality if they are not recognized and treated appropriately.18 Obtaining a detailed history about past allergic reactions, vaccinations, outside exposure, and previous medical ailments can be an important tool in diagnosing anaphylaxis.

  1. An analysis of 32 fatalities thought to be due to food-induced anaphylaxis revealed that peanuts likely were the responsible food in 62% of the cases. In placebo-controlled food challenges, peanut-sensitive patients can react to as little as 100 µg of peanut protein. [10] The Rochester Epidemiology Project, in agreement with earlier studies, found that food ingestion was the leading cause of anaphylaxis, accounting for as many as one third of all cases. [11]
  2. Two distinct physiologic responses occur in mammals experiencing hypovolemia.

Patients should be instructed to keep an epinephrine autoinjector with them at all times; they should also carry diphenhydramine and take this in conjunction with use of the epinephrine autoinjector. They should be instructed to keep the device from extremes of temperature. Epinephrine is sensitive to both light and temperature and therefore should not be stored, for example, in a refrigerator or in a motor vehicle glove compartment. They also should be instructed to replace any epinephrine autoinjector before its expiration date.Additional mediators activate other pathways of inflammation: the neutral proteases, tryptase and chymase; proteoglycans such as heparin and chondroitin sulfate; and chemokines and cytokines. These mediators can activate the kallikrein-kinin contact system, the complement cascade, and coagulation pathways. The development and severity of anaphylaxis also depend on the responsiveness of cells targeted by these mediators.

Make an appointment to see your doctor if you or your child has had a severe allergy attack or signs and symptoms of anaphylaxis in the past.Desensitization: The specific immunotherapy can be used for prophylactic sensitization to specific allergens, e.g. bee or wasp venom and certain types of pollen. A steady increase of the injected (subcutaneous or sublingual) antigen in minimal dosage can achieve a physiological reaction rather than an excessive IgE-antibody production. Especially younger patients with a monovalent allergy benefit from desensitization therapy.The best ways to manage your condition are: •    Avoid allergens that trigger your allergic reactions •    Be prepared for an emergencyReactions to aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) in the past have been classified as IgE-independent because they were thought to occur from aberrant metabolism of arachidonic acid.Bock SA, Muñoz-Furlong A, Sampson HA.

Cutaneous signs are the most common initial clinical sign of an allergic reaction but may be a precursor for more severe reactions, such as anaphylaxis. If severe anaphylaxis has a rapidly acute onset, cutaneous signs may be absent. The most common cutaneous clinical signs include erythema, urticaria, pruritus, wheals, and angioedema. These signs are often short in duration.Smith PL, Kagey-Sobotka A, Bleecker ER, et al. Physiologic manifestations of human anaphylaxis. J Clin Invest. 1980 Nov. 66(5):1072-80. [Medline].

Anaphylaxis is a medical emergency that requires immediate recognition and intervention. Disposition of patients with anaphylaxis depends on the severity of the initial reaction and the response to treatment.The most common anaphylaxis triggers in children are food allergies, such as to peanuts, and tree nuts, fish, shellfish and milk. Besides allergy to peanuts, nuts, fish and shellfish, anaphylaxis triggers in adults include:Anaphylaxis is a severe and rapidly developing systemic hypersensitivity reaction that is associated with the skin rash, urticaria.Scombroid fish poisoning can occasionally mimic food-induced anaphylaxis. Bacteria in spoiled fish produce enzymes capable of decarboxylating histidine to produce biogenic amines, including histamine and cis-urocanic acid, which is also capable of mast cell degranulation.

The ants' poison contains toxins, so the victim might have an allergic reaction or an anaphylactic shock Food-induced anaphylaxis often produces skin reactions and respiratory symptoms while drug- or venom-induced anaphylaxis more often produces shock. Symptoms usually occur within 5–60 minutes of contact with the allergen, but sometimes happen after several hours, or even 3–4 days later. Fast onset and rapid progression of symptoms usually indicate severe, life-threatening anaphylaxis. One or more organ systems may be involved. Typical features are described below.

The best way to understand anaphylaxis and the things that can trigger this severe allergic reaction is to see an allergist who will help you manage your condition.Signs of anaphylaxis may be categorized based on the affected organ system: cutaneous, respiratory, cardiovascular, or gastrointestinal.16

Signs and symptoms include:When either a penicillin or a cephalosporin is the drug of choice for a patient with a life-threatening emergency, a number of options exist. When the history is indefinite, the drug may be administered under close observation; however, when possible, obtain the patient’s informed consent. Immediate treatment measures for anaphylaxis should be available. Alternatively, when the history is more convincing, an alternative agent should be chosen if it provides similar efficacy or one must pursue a desensitization protocol.

Anaphylaxis and Treatment of an Anaphylactic Reactio

Many other drugs have been implicated in IgE-mediated anaphylaxis, albeit less frequently. In the surgical setting, anaphylactic reactions are most often due to muscle relaxants but can also be due to hypnotics, antibiotics, opioids, colloids, and other agents. The prevalence of latex allergy was higher during the 1980s (due to the HIV and hepatitis B and C epidemics and the institution of universal precautions), but the incidence has decreased significantly since the widespread use of latex-free materials. If latex is responsible for anaphylaxis in the perioperative setting, reactions tend to occur during maintenance anesthesia, whereas other agents tend to cause reactions during the induction of anesthesia. Volatile anesthetic agents can cause immune-mediated hepatic toxicity but have not been implicated in anaphylactic reactions.

While pretreatment with antihistamines is widely practiced to prevent the onset of anaphylaxis, studies show that their use during anaphylaxis may not relieve serious clinical signs. However, they may be administered in an effort to downregulate the release of more mediators during treatment.20Kemp SF.

Overall, 85% of patients either were in remission or reported diminished symptom severity in a subsequent episode or episodes. The Memphis study evaluated a referral population and also deliberately excluded patients with anaphylaxis due to insect stings or SCIT. [29]

Patients should be instructed to have ready and prompt access to emergency medical services for transportation to the closest ED for treatment. They should also be instructed to obtain emergency medical care immediately after injecting the epinephrine because the effect is short lived (< 15 min) and biphasic reactions can occur.A population-based study from Rochester, Minnesota, found an average annual incidence of anaphylaxis of 58.9 cases per 100,000 person-years, which had increased from 46.9 cases per 100,000 in 1990. [11] Of identified causes, ingestion of a specific food was responsible for 33%, insect stings for 18.5%, and medications for 13.7%. Twenty-five percent of cases were considered idiopathic. Episodes of anaphylaxis occurred more frequently from July through September, a difference that is attributable to insect stings.Lieberman P, Nicklas RA, Randolph C, Oppenheimer J, Bernstein D, et al. Anaphylaxis--a practice parameter update 2015. Ann Allergy Asthma Immunol. 2015 Nov. 115 (5):341-84. [Medline]. The physiologic responses to the release of anaphylaxis mediators include smooth muscle spasm in the respiratory and gastrointestinal (GI) tracts, vasodilation, increased vascular permeability, and stimulation of sensory nerve endings. Increased mucous secretion and increased bronchial smooth muscle tone, as well as airway edema, contribute to the respiratory symptoms observed in anaphylaxis.

What Is Anaphylactic Shock? Allergic Reaction Symptoms

Anaphylaxis is a medical emergency that requires immediate recognition and intervention. Patient management and disposition are dependent on the severity of the initial reaction and the treatment response. Measures beyond basic life support are not necessary for patients with purely local reactions. Patients with refractory or very severe anaphylaxis (with cardiovascular and/or severe respiratory symptoms) should be admitted or treated and observed for a longer period in the emergency department or an observation area.Choo K, Sheikh A.

Both H1 and H2 antihistamines act as inverse agonists, not competitive antagonists. Inverse agonists differ from competitive antagonists in that when they bind to the receptor, they induce an opposite response instead of simply not causing receptor activation. H1 antihistamines have a higher affinity for H1R and may act to stabilize the receptors. H1 antihistamines are most effective in treating localized allergic reactions and include diphenhydramine, chlorpheniramine, and cyproheptadine. H1 antihistamines cross the blood–brain barrier; therefore, they may cause central nervous system depression.

In immunologic IgE-mediated reactions, patients do not show clinical signs at the initial allergen exposure. Upon reexposure, IgE antibodies are produced, and the allergen forms a “bridge” that cross-links these antibodies via a high-affinity receptor, FcεRI, located in the membrane of mast cells and basophils. After binding, antibodies cause mast cell and basophil activation and start the immediate hypersensitivity reaction. Cross-linking induces a membrane change, causing an influx of calcium ions into the cell that initiates degranulation and, thus, a release of mediators (eg, histamine). Interactions between mediators and host organs cause clinical signs to appear.2 The latter are often designated as anaphylactic reactions, of which anaphylactic shock is the most severe form. The expression of anaphylaxis is species-specific reaction [ri:ˈækʃən]Существительное. reaction / reactions Latex allergies are becoming more common in society, this is most likely due to the widespread use of latex. These reactions can vary from a local dermatitis reaction to an anaphylactic reaction. Approximately 1-3% of the population has a latex allergy, with 10-17% of this number being healthcare workers (Farrell & Dempsey 2013).
