We report five cases of cytomegalovirus infection in immunocompromised patients which were detected by either cytomegalovirus antigenemia assay or in situ hybridization. Four cases had leukemia and the other had chronic renal failure. All the three BMT recipients suffered from GvHD. Interestingly, there was an unique case of CMV disease without a history of BMT, which reminded us that CMV could attack immunocompromised patients who had not undergone transplantation, too. Four out of five cases died. We think that cytomegalovirus infection or disease should not be regarded as a minor problem in post-transplantation infection in Korea.

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.

Recent development of hematopoietic cell transplantation (HCT) has greatly improved the quality of life in critical patients with hematological malignancies. On the other hand, it is a fact that some HCT survivors suffer from chronic renal failure (CRF). We attempted to examine the clinical characteristics of CRF in patients who were successfully treated with HCT in Japan. A retrospective analysis of 158 long-term survivors receiving HCT at Komagome Hospital was undertaken. CRF was designated as less than 30 mL/min of estimated GFR (eGFR) calculated by the MDRD formula. We statistically analyzed the influences of total body irradiation (TBI), graft versus host diseases (GVHD), renal impairment during HCT, new incidence of hypertension after transplantation, age, and gender on CRF, using the multivariate logistic regression analysis. Twenty-seven patients (17.1%) had CRF. Their mean ages were 33.1 +/- 8.87 years and mean eGFR levels were 20.5 +/- 9.50 mL/min/1.73 m2. Fifteen patients were recipients of TBI (55.6 %). CRF became obvious within one year after BMT in 5 patients (18.5%) and later in 22 patients (81.5%). Seven patients(25.9%) finally reached end-stage renal disease (ESRD) at the time of over 10 years after HCT. Multivariate logistic regression analysis showed that TBI, renal impairment during HCT, and new incidence of hypertension after HCT were significantly associated with CRF. Considering that 12 patients without TBI (44.4%) developed CRF, "renal impairment during HCT", the odds ratio of which was the highest, might be the factor most closely associated with CRF. The clinical course of a representative patient who developed ESRD was described. An increase in ESRD patients receiving HCT should be anticipated and would constitute a new important issue in nephrology.
