Early high-dose immunosuppression in Henoch-Schönlein nephrotic syndrome may improve outcome.

AbstractOBJECTIVE:
Renal involvement in Henoch-Schönlein purpura (HSP) constitutes a risk of end-stage renal disease (ESRD), especially in patients presenting with nephrotic syndrome.
PATIENTS AND METHODS:
The clinical courses of six patients (mean age 13.2 years; four boys and two girls) admitted from 2000 to 2007 with HSP and nephrotic syndrome were reviewed. Average follow-up was 44 months (28-59). Treatment protocols included oral prednisolone and in non-responders cyclosporin A, cyclophosphamide, mycophenolate mofetil or tacrolimus. Five patients were treated immediately after presentation of nephrotic syndrome/nephrotic range proteinuria (median 277 mg/m(2)/h). The last patient was treated locally with low-dose prednisolone (0.2-0.9 mg/kg/day) and 3 months of low-dose cyclophosphamide (1 mg/kg/day).
RESULTS:
All five patients treated promptly with high-dose immunosuppressant had normal estimated glomerular filtration rate (eGFR) (median 159 ml/min/1.73 m(2)) at follow-up. One obtained complete remission, two had positive dipstick proteinuria and two needed angiotensin-converting enzyme inhibitors to stay normotensive. The patient receiving low-dose immunosuppression at onset progressed to ESRD 44 months later. At initial presentation eGFR, blood pressure, renal biopsy grading, proteinuric range and plasma albumin were similar in all patients.
CONCLUSION:
Follow-up data from the patients suggest that an early aggressive immunosuppressive approach improves long-term renal outcome in HSP patients with nephrotic syndrome.
