Insights
Henoch-Schönlein purpura (HSP) commonly affects children, presenting with skin rashes, GI issues, and joint pain. Most patients recover within a month with prednisolone treatment, indicating a good prognosis.
Area of Science:
- Pediatrics
- Rheumatology
- Nephrology
Background:
- Henoch-Schönlein purpura (HSP) is a common vasculitis affecting children.
- Understanding the clinical spectrum and outcomes of HSP is crucial for pediatric care.
Purpose of the Study:
- To analyze the clinical characteristics, management, and prognosis of Henoch-Schönlein purpura in pediatric patients.
- To identify common triggers and clinical manifestations of HSP.
Main Methods:
- Retrospective review of 50 pediatric patients diagnosed with Henoch-Schönlein purpura between 1983 and 1992.
- Analysis of clinical features, laboratory findings, treatment, and patient outcomes.
Main Results:
- The study included 50 patients (33 boys, 17 girls) aged 2-14 years, with peak incidence in autumn.
- Common symptoms included skin rash (100%), gastrointestinal (66%), and joint (58%) involvement; 30% had renal involvement.
- Prednisolone therapy was effective, with 72% of patients recovering within one month and an overall good prognosis.
Conclusions:
- Henoch-Schönlein purpura in children typically presents with characteristic symptoms and has a favorable prognosis.
- Early recognition and management, including prednisolone, contribute to successful recovery.
Abstract:
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.
