Anaphylactoid Purpura Manifested after Acute Gastroenteritis with Severe Dehydration in an 8-Year-Old Male Child: A Case Report

Abstract

Anaphylactoid purpura, also known as Henoch–Schönleinpurpura (HSP), is an IgA-mediated vasculitis that tends to be a benign disease of childhood. Up to 50% of cases are preceded by an upper tract respiratory infection caused by group-A beta-hemolytic streptococcus and present with the common tetrad of abdominal pain, arthritis, purpuric rash, and renal involvement. The majority of patients recover completely. Here we document a rare case of anaphylactoid purpura which manifested with skin lesions in the form of palpable purpura following about of acute gastroenteritis with severe dehydration; it was treated with a short regimen of steroid therapy, which resulted in the complete remission of the disease. We conclude that prompt diagnosis and multidisciplinary intervention will lead to appropriate management—consisting of the installation of early short-course steroid therapy and thus, prevent further complications and the recurrence of the disease.
