Introduction
Henoch-Schönlein purpura (HSP) is non-contagious, as it has no infectious source or route of transmission. 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 exhibit potent anti-allergic effects.
Allergic purpura, also known as acute vascular purpura, is frequently misunderstood by many as a contagious condition. Is this truly the case? The details are as follows:
Allergic purpura is not contagious, as it has neither an infectious source nor a route of transmission. Rather, it is a common immune-mediated disorder.
Current treatment for allergic purpura typically involves selective pharmacotherapy. For instance, rutin compound tablets may be prescribed, supplemented with certain vitamins and calcium gluconate. This combined regimen yields favorable therapeutic outcomes and effectively alleviates localized petechiae in patients.
In patients with severe rashes, fever may also occur. In such cases, corticosteroids—particularly prednisone—may be selectively administered. Corticosteroids possess potent anti-allergic properties and can reduce vascular permeability, thereby rapidly relieving patients’ discomfort.
Most patients experience marked clinical improvement following treatment. For those with severe renal involvement, high-dose corticosteroid pulse therapy may be employed, which also demonstrates satisfactory efficacy.
