Popis: Dysfunction of the B lymphocyte, an important component of adaptive immunity, is thought to be important in the pathogenesis of lupus nephritis (LN). There are several novel strategies emerging including B-cell depletion by the monoclonal antibodies to B-cell markers, rituximab. We describe an unusual clinical response of a 22-year-old Hispanic woman with class IV LN with vasculitis while on dialysis to cyclophosphamide (CY) and adjunct rituximab. The patient had a history of class III/V LN and was treated with nine months of CY and maintenance therapy with mycophenolate mofetil (MMF) for three years. While on MMF, the patient deve-loped class IV LN with vasculitis leading to end-stage renal disease (ESRD). While the patient was on peritoneal dialysis, the patient was treated with two doses of rituximab and six doses of intravenous CY. The patient responded to this regimen and recovered kidney function within four months. The kidney function remained stable nine months after discontinuing peritoneal dialysis.
