title: Hematopoietic stem cell transplantation in patients with chronic kidney disease.
abstract: Patients with significant medical comorbidities such as chronic kidney disease (CKD) traditionally have been excluded from hematopoietic stem cell transplantation (HSCT) because of unacceptably high transplant-related morbidity and mortality, an exclusion that can have enormous consequences for patients with CKD from myeloma in particular. Much of the excess HSCT-related morbidity among CKD patients relates to the toxic effects of conditioning regimens, which have a narrow therapeutic index even in patients with normal renal function. Common posttransplant complications are more challenging to prevent and manage in patients with CKD. In selected centers, autologous HSCT is performed with some frequency in patients with advanced CKD and even dialysis-dependent end-stage renal disease (ESRD), with acceptable outcomes, but cure from malignancy rarely is obtained. Allogeneic transplants using reduced-intensity conditioning regimens are being used with increasing frequency in patients with CKD, for both nonmalignant and malignant conditions, relying in the latter case on a graft-versus-malignancy effect to eliminate residual malignancy. In patients with ESRD from myeloma who have suitable donors, simultaneous allogeneic HSCT and kidney transplantation from a human leukocyte antigen-identical sibling provides the opportunity to treat both the malignant condition and the ESRD, avoiding the risks of posttransplant care in a dialysis-dependent patient and freeing the patient of the subsequent burdens of both ongoing dialysis and immunosuppression.
