As mentioned above, atopy is a risk factor for anaphylaxis. In the Rochester Epidemiology Project, 53% of the patients with anaphylaxis had a history of atopic diseases (eg, allergic rhinitis, asthma, atopic dermatitis). [11] The Memphis study detected atopy in 37% of the patients. [29] Other studies have shown atopy to be a risk factor for anaphylaxis from foods, exercise-induced anaphylaxis, idiopathic anaphylaxis, radiocontrast reactions, and latex reactions. Underlying atopy does not appear to be a risk factor for reactions to penicillin or insect stings.
