Purpose :$Henoch-Sch""{o}nlein$ purpura(HSP) is usually a self-limited disease with a good eventual outcome. The prognosis of HSP is mainly determined by the renal involvement. In this study, We evaluated children with biopsy-proven $Henoch-Sch""{o}nlein$ purpura nephritis about the clinical outcome correlated with renal manifestation and morphologic findings. Methods : The clinical features, initial laboratory and pathologic findings, and clinical out-come were evaluated in 60 children with biopsy-proven $Henoch-Sch""{o}nlein$ purpura nephritis at Yonsei University Severance Hospital during the period from Jan. 1990 to Dec. 2002. Results : The ratio of male to female patients was 1.2:1. The interval between the onset of $Henoch-Sch""{o}nlein$ purpura and renal manifestation was less than 3 months in 81% of the patients. Initial renal manifestation was microscopic hematuria in 100% of patients, isolated hematuria in 15%, acute nephritic syndrome in 7%, nephrotic syndrome In 22% of patients. Renal manifestation correlated with clinical outcome. Grade II and III were the most common in histologic grades of ISKDC. Renal pathologic finding correlated with clinical outcome. Conclusion : Renal manifestation and pathologic findings correlated with the clinical out-come. It is necessary to evaluate the correlation between pathologic findings and treatment.
