Rituximab in adult patients with immunosuppressive-dependent minimal change disease.

Minimal change disease (MCD) is one of the leading causes of nephrotic syndrome. Steroid therapy is effective in achieving remission, but relapses, steroid dependence, and steroid resistance are therapeutic challenges. The use of second-line agents such as cyclophosphamide is associated with toxicity and adverse effects. Therefore, we studied the effect of rituximab (RTX) on proteinuria in adult patients with immunosuppressive (IS)-dependent MCD.
