Hematopoietic cell transplantation is a common procedure for the treatment of malignancies and some non-malignant hematologic disorders. In addition to other transplant-related organ toxicities, acute renal failure is a common complication following transplantation. This review discusses the incidence, timing, etiologies, risk factors, and prognosis of renal failure associated with three commonly used transplantation procedures - myeloablative autologous, myeloablative allogeneic, and non-myeloablative allogeneic transplantation. ⋯ Moreover, mortality is >80% for patients with renal failure requiring dialysis. It also appears that surviving patients have an increased risk of chronic kidney disease after renal failure. The reduction of acute renal failure will have several advantages, including reducing mortality and the burden of chronic kidney disease following transplantation.

CommentHypertension, race, and glomeruli: more than simply a numbers game.
Incidences of hypertension and hypertension-related renal failure are considerably higher in African-Americans than in white Americans. One explanation offered for this is that African-Americans have a higher incidence of low birth weight, the latter associated with lower numbers of glomeruli. However, although studies show a clear association between hypertension and glomerular number in whites, the situation in African-Americans appears more complex.

Hypoxia-inducible factor (HIF) is a family of transcription factors that regulate the homeostatic response to oxygen deprivation during development, physiological adaptation, and pathological processes such as ischemia and neoplasia. Our understanding of the function of different HIF isoforms is being advanced by understanding the processes that regulate their activity, learning where and when they are expressed and what genes they regulate.
