This was achieved using a treatment regimen of plasma exchange, high-dose corticosteroids, cyclophosphamide and rituximab. Despite a number of poor prognostic factors, including requirement for dialysis during the index admission and a high proportion of crescents on diagnostic biopsy, the patient was able to achieve renal recovery. This case report adds to the limited literature supporting the use of rituximab as part of the treatment regimen of dual-positive
