title: Effect of early corticosteroid therapy on development of Henoch-Schönlein nephritis.
abstract: BACKGROUND
  Henoch-Schönlein purpura (HSP) is a systemic, small vessel vasculitis, which is very common among pediatric population. Findings of previous reports addressing the preventive effect of corticosteroid treatment in HSP nephritis have been inconsistent. The aim of this study was to determine whether corticosteroid therapy was effective in preventing Henoch-Schönlein nephritis.
  
  
  METHODS
  The medical records of 216 children with HSP, seen in 2 tertiary care pediatric nephrology centers, were reviewed retrospectively. The effect of corticosteroid therapy on preventing nephritis was assessed in 157 patients who had no evidence of nephritis at the initial urinalysis. The treatment group (n=61) had received oral corticosteroids for gastrointestinal symptoms and/or arthritis. The dosage of prednisone was 1 mg/kg per day for 1-2 weeks, with weaning over a week. We compared the rate of renal involvement during follow-up between the groups who were treated with corticosteroids and not.
  
  
  RESULTS
  Nephritis developed in 17 of the 61 (27.8%) corticosteroid-treated patients and 18 of the 96 (18.7%) untreated patients during follow-up.
  
  
  CONCLUSIONS
  There was no evidence that corticosteroids reduced the risk of renal involvement in HSP, and these results do not support the use of corticosteroids in early HSP to prevent renal injury.
