Over a 9-year period from 1983 to 1992, 50 patients with Henoch-Schönlein purpura were admitted to the Department of Pediatrics, Taichung Veterans General Hospital. There were 33 boys and 17 girls, with a male to female ratio of 2:1. Their ages ranged from 2 to 14 years with a mean of 6.3 years. Seventy percent of the patients were over the age of five. The months of peak incidence were October to December (48%). Fifty-four percent of the patients had evidence of preceding infections. The main clinical features were skin rashes (100%) followed by gastrointestinal symptoms (66%), joint symptoms (58%), soft tissue edema (30%) and renal involvement (30%). Hemograms showed leukocytosis, thrombocytosis, and elevated erythrocyte sedimentation rate in about half of these patients. Serological examinations were nonspecific; anti-streptolysin O titers were elevated in 40% of the patients. Forty-two percent of our patients had elevated serum IgA levels which bore no relationship to the symptomatology and duration of the illness. One patient had a complication of intussusception requiring surgical reduction. Another patient who had renal involvement progressed to end-stage renal disease. Eighty-two percent of our patients received prednisolone therapy at a dose of 1-2 mg/kg/day, with good response. Seventy-two percent of the patients recovered completely within one month after the onset of the malady. The overall prognosis remains good.
