Henoch–Schönlein purpura associated with hepatitis A infection

common vasculitis conditions of childhood, and is characterized by nonthrombocytopenic purpura, arthritis and/or arthralgia, abdominal pain, gastrointestinal hemorrhage and renal involvement. Although the etiology of HSP is still unknown, it is considered to be an immune-mediated vasculitic disorder resulting from an immune complex reaction to various antigenic stimuli. Many bacterial and viral organisms such as streptococci, adenovirus, parvovirus, hepatitis B virus (HBV), Epstein–Barr virus, varicella and mycoplasma have been reported as predisposing factors for HSP.1 So far, HSP associated with hepatitis A virus (HAV) infection has only been reported in one other patient, as a letter to the editor.2 In the present report we describe two patients with HSP associated with acute hepatitis A.
