Nephrotic Syndrome
Conditions
Brief summary
The vast majority of children with idiopathic nephrotic syndrome respond well to corticosteroid treatment. However, as many as 20% experience a more complicated course with steroid resistance (SRNS). Repeated and prolonged courses of steroids in these children often result in long-term complications. The goal of treatment is to reduce the rate of relapses, the cumulative dose of corticosteroids, and the incidence of serious complications. In order to minimize the side effects of steroid therapy, different steroid sparing agents such as cyclophosphamide, calcineurin inhibitors(CNI), levamisole, and mycophenolate mofetil (MMF) have been used in SRNS. Whereas CNI are usually considered the steroid sparing drug class of first choice, rituximab is increasingly used as alternative to minimize CNI toxicity. Various prospective studies suggest that Rituximab, a B cell depleting monoclonal antibody, could be a safe and effective alternative to steroid or immunosuppressants to achieve and maintain remission in this population. Rituximab infusion have been shown to be efficacious for 6 to 12 months and the side effect profile observed to date is very benign. Studies comparing the usefulness of these agents are lacking. In this proposed randomized controlled trial, the investigators want to compare the efficacy and safety of CNI to that of Rituximab in treating children with SRNS.
Interventions
DRUGRituximab
Two to four rituximab infusions (over 2-4 weeks) will be administered once every week at standard dose (Intravenous infusion of rituximab 375mg/mt2)depending on circulating B cells level.
DRUGTacrolimus
Standard dose with oral Tacrolimus 0.2 mg/kg/day in two divided doses till 6 month of relapse free survival.
