Background. Patients, especially children, with steroid-dependent or multirelapsing nephrotic syndrome (NS) secondary to minimal change disease (MCD) or idiopathic focal and segmental glomerulosclerosis (FSGS) on continuous treatment with steroids and/or other immunosuppressive agents to limit or prevent recurrences are at increased risk of severe drug-related adverse events. Case reports 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.
