Chronic renal failure is an acknowledged late complication of BMT. It is related to the intensive chemotherapy, radiation and supporting medications. Polymorphism in the angiotensin converting enzyme (ACE) gene is associated with progression of nephropathy caused by diabetes and IgA nephropathy. We sought to determine whether ACE genotype and other clinical factors were associated with loss of renal function after BMT. We determined the genotype of 106 adult allogeneic BMT recipients, who received a similar preparative regimen, survived 1 year, and had assessment of renal function up to 3 years after BMT. We found that the distribution of genotypes was similar to the general population; 29%, 51%, and 20% for the DD, DI, and II genotypes, respectively. There was no statistical difference in patient survival between the three groups. Among all patients, the average creatinine clearance declined from 124 (95% CI 117, 131) to 89 (95% CI 78, 100) ml/min over the 36 months after BMT. Decline in renal function over time was less for patients with the DD compared to the II genotype (P = 0.040). Renal function in patients with the DD genotype was also better than those with the DI genotype, but this was of borderline statistical significance (P = 0.055). Renal shielding reduced decline in renal function compared to no shielding (P = 0.026). We conclude that the ACE genotype does not seem to influence survival, but the DD genotype may be protective against renal injury after BMT. Furthermore, we confirm that renal shielding during TBI reduces the renal injury after BMT.

We report a patient who developed chronic renal failure 11 months after an allogeneic hematopoietic stem-cell transplantation (HSCT) for Ph1(+) acute lymphocytic leukemia. Renal biopsy showed typical pathological findings compatible with a bone marrow transplant nephropathy (BMT nephropathy). The general course of BMT nephropathy is slowly progressive, eventually reaching endstage renal failure. Intervention therapy with an angiotensin-converting enzyme inhibitor (ACE-I), temocapril, was started for this patient, based on several experimental reports showing the protective effects of ACE-Is on BMT nephropathy. After the induction of ACE-I in this patient, the rate of regression of renal function was significantly reduced and his serum creatinine was maintained at almost the same level for 18 months. Although the course of observation in this patient was short, we clearly showed the effects of an ACE-I on preventing BMT nephropathy from progressing to endstage renal failure in a human rather than in an experimental model.
