Idiopathic nephrotic syndrome is one of the most common glomerular disease in children, although most of cases respond to steroid treatment (>80%) approximately 40% develop refractory nephrotic syndrome, these patients usually treated with high dose of steroid in addition to immunosuppressant. As its difficult to use this immunosuppressant’s for long time because of their serious side effects. Ritiximub is a monoclonal antibody directed against the CD20 receptor on B-cells, has been successfully used to treat patients with refractory nephrotic syndrome, and it’s significantly reduce the use of steroid and immunosuppressant. Its considered that ritiximub is relatively well tolerated in children with nephrotic syndrome, with minimal side effect. Still no established regimen dose, some center used single dose of 357mg/m2 some used repeated doses 2-4 in weekly intervals. The aim of this literature review is to asses efficacy and safety of ritiximub in treating childhood refractory nephrotic syndrome, and to review different protocols of ritiximub doses, and its efficacy in long remission.
