Purpose : Henoch-Schonlein Purpura(HSP) is a self-limited systemic small vessel vasculitis, however, renal involvement is considered to contribute to the outcome of this disease. Therefore, identifying the renal risk factors in HSP and prevention of renal involvement are important. The aim of this study is to investigate whether early steroid administration in HSP could reduce the rate of renal involvement.
Methods : We retrospectively studied two hundred children with HSP. We had administrated steroids orally to resolve of severe abdominal pain, joint and scrotal symptoms. We analyzed the relationship between the steroid therapy to relieve systemic symptoms and the subsequent renal involvement in HSP.
Results : There were no significant differences in the incidence and duration of renal involvement according to steroid administration and its duration. In HSP patients with renal manifestations, steroid administration group showed a tendency of hematuria and steroid non-administration group showed a tendency of proteinuria, however, we could not find statistically significant differences in each group. There was no significant difference in the duration of purpura presence according to steroid administration. However, persistent purpura increased the incidence and the duration of renal involvement.
Conclusion : Early steroid administration did not reduce the risk of renal involvement, therefore, steroid could not prevent delayed nephritis in children with HSP. On the other side, persistent purpura, known to be not related to steroid therapy, was associated with renal involvement. We suggest that early steroid administration could not be useful in preventing the renal involvement in HSP.
