Sammanfattning
Bee and wasp stings can cause allergic reactions. Although the local reactions are more frequent, anaphylaxis due to insect stings can be potentially fatal. Rapid
recognition of anaphylaxis is therefore critical and reactions should immediately be treated with i.m. adrenaline. Patients having experienced anaphylaxis should be
referred to an allergist for diagnostic evaluation and possible venom-immunotherapy (VIT). The clinical history is essential in diagnosis of venom allergy as the test
results are not always reliable. Diagnostic testing with venom components might be beneficial in appropriate patients. The analysis of serum tryptase from the acute
episode can be crucial. Mastocytosis is associated in about 8 percent of patients with severe anaphylaxis from insect stings and should be considered in the differential
diagnosis. VIT is indicated for patients with a history of anaphylaxis and is effective in preventing future anaphylaxis from Hymenoptera stings.
