Acute renal failure following bone marrow transplantation

Area of Science:

• Nephrology
• Hematology
• Transplantation Medicine

Background:

• Acute renal failure (ARF) is a frequent and life-threatening complication post-bone marrow transplantation (BMT).
• Specific renal syndromes occur with high frequency following BMT, necessitating timely classification and management.
• ARF post-BMT is often multifactorial, complicating treatment approaches.

Purpose of the Study:

• To classify ARF syndromes based on time of onset post-BMT.
• To outline the common etiologies and clinical presentations of ARF in BMT patients.
• To emphasize the importance of ARF prevention strategies in the BMT setting.

Main Methods:

• Classification of ARF by time of onset: immediate (within 5 days), early (within 1 month), and late (more than 4 weeks).
• Identification of specific syndromes: tumor lysis syndrome, marrow-infusion toxicity, hepatorenal-like syndrome, BMT-associated nephropathy, and cyclosporin nephrotoxicity.
• Consideration of non-specific causes: sepsis, hypotension, volume depletion, nephrotoxic agents, and obstructive uropathy.

Main Results:

• Immediate ARF syndromes include tumor lysis syndrome and marrow-infusion toxicity.
• Hepatorenal-like syndrome is the most common cause of early ARF.
• Late ARF includes BMT-associated nephropathy and cyclosporin nephrotoxicity.

Conclusions:

• ARF post-BMT requires classification based on onset time to guide management.
• Supportive care and dialysis are key, but specific therapies are limited.
• Prevention through hydration, avoiding nephrotoxins, and early infection management is paramount.
