Sirs,

We read with great interest the article titled, “Effect of different rituximab regimens on B cell depletion and time to relapse in children with steroid-dependent nephrotic syndrome” by Dr. Hogan et al. [1]. Based on the retrospective study of 61 French patients receiving various initial rituximab (RTX) regimens (single low dose of 100 mg/m2, single standard dose of 375 mg/m2, or two standard doses of 375 mg/m2), the authors showed that a lower initial dose of RTX and younger age at RTX initiation were significantly associated with a shorter time to B cell reconstitution, which may have an impact on the increased risk of nephrotic syndrome (NS) relapse. The authors also reported that the need for methylprednisolone pulses to achieve remission and a high level of steroid dependency requiring cyclosporine A (CsA) before RTX administration were significantly associated with a higher risk of NS relapse following RTX treatment. They concluded that the initial RTX dose could be...
