A 21-year-old male developed massive proteinuria and microscopic hematuria, 1 year after allogeneic BMT for acute lymphoblastic leukemia. These symptoms occurred during an exacerbation of chronic cutaneous graft-versus-host disease (GVHD). Renal biopsy revealed granular deposits of IgG and IgM along the glomerular basement membrane, and subepithelial electron dense deposits. A diagnosis of membranous nephropathy was made. With prednisolone therapy proteinuria decreased gradually, and amelioration of cutaneous lesions was also noted. It was speculated that the disordered immune regulation of chronic GVHD resulted in the development of immune complex nephritis.

The (NZW x BXSB)F1 (W/BF1) mouse is known to be an animal model of systemic lupus erythematosus (SLE) and immune thrombocytopenic purpura (ITP). These mice produce not only anti-DNA antibodies but also anti-platelet antibodies, resulting in decreased platelet counts. They show a high level of proteinuria, increased white blood cell (WBC) counts, hypertension, and myocardial infarction due to the high levels of anti-cardiolipin antibodies. When W/BF1 mice (4-5 months) were lethally irradiated and then reconstituted with T cell-depleted bone marrow cells of normal BALB/c mice (8 weeks), 60% of the mice survived more than one year. The WBC and platelet counts in the mice were normalized, and the levels of anti-DNA and anti-platelet antibodies decreased. The renal dysfunction was also ameliorated as indicated by a lower level of proteinuria, lower levels of serum creatinine (S-CRTN) and blood urea nitrogen (BUN), and by improved histology. The blood pressure (BP) of the treated W/BF1 mice decreased due to the improved renal functions. In contrast to the non-treated W/BF1 mice which died of myocardial infarction or renal failure by the age of 7 months, the treated W/BF1 mice showed no evidence of myocardial infarction even one year after BMT. This was due to the lower cardiolipin levels.

A 13-yr-old boy was diagnosed as T cell lymphoma. After the second remission, he underwent BMT from an HLA-identical, MLC negative sibling donor. After BMT, he developed grade II acute GVHD. GVHD was improved by pulsed steroid therapy using prednisolone. About 12 months after BMT, he developed bronchiolitis obliterans, sicca syndrome, and leukoderma, which were related to chronic GVHD. Pulsed steroid therapy was carried out twice, and his condition improved. Twenty-seven months after BMT, he developed nephrotic syndrome. A renal biopsy was performed, and the diagnosis was histologically membranous nephropathy and focal glomerular sclerosis. The response to steroids was not satisfactory. After 5 weeks, dipyridamole was added, but proteinuria persisted. Proteinuria disappeared 8 weeks after the addition of cyclosporine. The second biopsy after 5 months of treatment revealed an improvement in the renal lesions. The patient showed a low T4 to T8 ratio of T-lymphocytes at the onset of nephrotic syndrome. However after treatment with cyclosporine, the ratio gradually increased. These findings suggested the nephrotic syndrome in this patient was related to renal involvement in the course of chronic GVHD.

Angiotensin-converting enzyme (ACE) inhibitors can be used to prevent the development of radiation nephropathy after BMT. In previous BMT nephropathy studies, ACE inhibitor therapy was started pre-BMT and continued indefinitely. In preparation for clinical trials, studies were designed to determine whether effective prophylaxis could be achieved if ACE inhibitor therapy was started after engraftment, and to determine whether ACE inhibitors needed to be given indefinitely. The present studies in our rat syngeneic BMT model showed that captopril therapy started 25 days post-BMT was as effective as therapy started prior to BMT. When ACE inhibitor therapy was discontinued 28 weeks after BMT, the protective effect was not lost if adequate control of azotemia had been maintained for 26 weeks. If adequate control of azotemia was not maintained for 26 weeks, BMT nephropathy progressed rapidly when ACE inhibitor therapy ended, and slowly when it was continued. Failure to control azotemia was a better predictor of renal failure than failure to control hypertension or proteinuria. Based on these preclinical studies, it would appear that ACE inhibitor therapy will be effective in the prophylaxis of BMT nephropathy even if begun after engraftment, and that ACE inhibitors may not need to be given indefinitely.

We report a child with T cell acute lymphoblastic leukemia who developed late-onset multiple complications after allogeneic bone marrow transplantation from an HLA-matched sibling. The preparative regimen consisted of total body irradiation (TBI, 12 Gy), splenic irradiation (6 Gy) and cytosine arabinoside (3 g/m2 x 10). Splenic irradiation was added because of persistent splenomegaly in spite of intensive chemotherapy. He developed bronchial asthma 1 1/2 years post transplant. He presented with microhematuria and proteinuria 4 1/2 years post-transplant, which were due to unilateral left renal dysfunction. He developed type II, non-insulin-dependent diabetes mellitus 8 years post-transplant. A biopsy from the left kidney was not compatible with diabetic nephropathy. All these complications appear to be independently related to BMT, particularly TBI and/or splenic irradiation.
