Introduction
Henoch-Schönlein purpura (HSP) is non-contagious, as it has no infectious source or transmission route. It is a common immune-mediated disorder. In patients with severe skin rash, fever may also occur; in such cases, corticosteroids may be selectively administered, as they possess potent anti-allergic effects.
Allergic purpura, also known as acute vascular purpura, is a condition unfamiliar to many. Due to a lack of understanding about the disease, some people mistakenly believe it is contagious— but is this actually true? Does allergic purpura have infectious potential? The details are as follows:
Allergic purpura is not contagious, as it has neither an infectious source nor a transmission route. It is, in fact, a common immune-mediated disorder.
Current treatment for allergic purpura typically involves selective pharmacotherapy. For instance, rutin compound tablets may be prescribed, often combined with vitamin supplementation and calcium gluconate administration; this combination therapy yields favorable results and effectively alleviates localized petechiae.
In patients presenting with severe rashes and associated fever, corticosteroids may be selectively administered. Corticosteroids possess potent anti-allergic properties and can reduce vascular permeability, thereby rapidly relieving patients’ discomfort. Prednisone is one commonly used corticosteroid option.
Most patients experience marked clinical improvement following treatment. In cases of severe renal involvement, high-dose corticosteroid pulse therapy may be employed, which also demonstrates good therapeutic efficacy.
