Anaphylaxis is a serious and very lethal allergic reaction which may cause rapid death. This severe reaction occurs when an over-release of chemicals by the immune system puts the person into shock. Factors responsible for the anaphylaxis include certain foods, some medications, insect venom and latex. Anaphylaxis requires immediate medical treatment, including an injection of epinephrine.Symptoms of Anaphylaxis occur within minutes or hours as soon as exposed to allergen. The early symptoms may be mild, such as a runny nose, and nausea and vomiting. Common causing agents are venom from insect bites or stings, foods and medication. Many foods can trigger anaphylaxis ingestion of or exposure to peanuts, wheat, nuts, and certain types of seafood like shellfish, milk, and eggs are the most prevalent causes. Any medication may potentially trigger anaphylaxis. Venom from stinging or biting insects may cause anaphylaxis in susceptible people. People with atopic diseases such as asthma, eczema, or allergic rhinitis are at high risk zone.
Anaphylaxis is a serious allergic reaction affecting many systems of the body. It is caused majorly due to the release of inflammatory mediators and cytokines from mast cells and basophils, typically due to an immunologic reaction but sometimes non-immunologic mechanism.Anaphylaxis is diagnosed on the basis of its symptoms. People with a history of allergic reactions may be at greater risk for developing a severe reaction in the future. Allergists have expertise to review the history of allergic reactions conducts diagnostic tests (such as skin-prick tests, blood tests and oral food challenges) to determine the factors and suggesting the treatment accordingly.
An anaphylactic attack can be treated immediately with an injection of epinephrine, Oxygen, Intravenous (IV) antihistamines and cortisone or beta-agonist. At risk of anaphylaxis, carry auto injectable epinephrine (adrenaline). This is a single dose of medication that is injected into the thigh during an anaphylactic emergency. The best ways to manage condition are avoid allergens that trigger your allergic reactions.In Japan the prevalence rate for anaphylaxis is estimated to be approximately about 5.5percent of the overall population.
