Treatment of Renal Sarcoidosis by Methylprednisolone Bolus

Not Applicable
Terminated
Conditions
Renal Sarcoidosis
Interventions
Registration Number
NCT01652417
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

Renal sarcoidosis treatment is based on steroids, but the dose and duration are unknown. Despite this treatment, most patients will have chronic kidney disease. From our previous studies, the investigators believe that high dose steroids by methylprednisolone bolus will improve patient outcome and renal function.

Detailed Description

In a multicentric, randomized, open trial, the investigators will assess the efficacy of methylprednisolone bolus at 15mg/kg/d for 3 days before oral steroids on renal function improvement in renal sarcoidosis patients.
