Clinical review describes the pathophysiology, diagnostic testing, and management of cholinergic urticaria and exercise-induced anaphylaxis, highlighting critical distinctions between the two.
In this article, we will present the physical manifestations of two similar conditions. The first is cholinergic urticaria. This is chronic urticaria precipitated by an elevated body temperature. The second is exercise-induced anaphylaxis. Anaphylaxis can be idiopathic, a result of a specific allergenic trigger (food, medication, or insect sting), or exercise induced. We will focus on the third subtype. We describe the causes, symptoms, pathophysiology, testing, treatment, and prognosis of these two conditions.
