A 43-year-old man developed the nephrotic syndrome 26 months after allogeneic bone-marrow transplantation for chronic myeloid leukemia. This occurred during an exacerbation of graft-versus-host disease (GVHD) and both problems remitted after therapy with cyclosporine and prednisolone. Renal biopsy showed ultrastructural and immunofluorescence evidence of membranous nephropathy. Anti-nuclear antibodies (but not antiglomerular or anti-renal tubular epithelial antibodies) were detected in his serum. Experimental GVHD in mice has been associated with immune complex glomerulonephritis and the presence of IgG autoantibodies which has been attributed to abnormal T (donor)/B (recipient) cell co-operation. This association can be extrapolated to the human GVHD where autoantibody formation is better described than immune complex glomerulonephritis.

A 42-year-old man with chronic myelogenous leukemia underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) from an unrelated donor in January 1998. About 100 days later, he developed skin eruption and a diagnosis of chronic graft-versus-host disease (cGVHD) was made by skin biopsy. The eruption improved with steroid therapy, and the dose of steroid was gradually tapered. On day 151, the patient developed nephrotic syndrome with proteinuria up to 20 g/day. A renal biopsy carried out on day 160 showed minimal change in the glomeruli. The proteinuria disappeared 19 days after the onset of nephrotic syndrome without any additional therapy, and no recurrence was observed upon re-tapering of the steroid. In this case, cGVHD might have been related to development of the nephrotic syndrome. Nephrotic syndrome after allo-HSCT is a rare complication, and only ten cases have been reported. The histological findings were mainly membranous nephropathy, and immunosuppressive therapy was effective. As seen in this case, transient nephrotic syndrome with cGVHD may occur after allo-HSCT, and care is necessary to ensure that treatment of cGVHD is sufficient.

A 15-year-old boy developed nephrotic syndrome and acute renal failure 4 years after allogenic bone marrow transplantation (BMT) for lymphoid crisis of chronic myelocytic leukemia. On admission, he presented with clinical features of chronic GVHD including transient exacerbation of cholestatic liver injury. Renal biopsy showed diffuse proliferative glomerulonephritis with cellular crescents. The patient was treated with methylprednisolone pulse therapy (1 g/day, for 3 days) followed by oral prednisolone. Renal function gradually improved but nephrotic state was persistent. A second renal biopsy showed improvement of acute tubular necrosis and endocapillary proliferation and transformation of crescents into a fibrous form. After tapering of oral prednisolone, cyclophosphamide was started, which resulted in a gradual improvement of proteinuria. Several cases of nephrotic syndrome occurring after BMT have already been reported, but most cases had membranous nephropathy. In our case, renal biopsy revealed diffuse proliferative glomerulonephritis with findings of active cellular immunity, and aggressive treatment resulted in attenuation of these findings. Moreover, chronic GVHD-related liver injury was noted at the time of this episode. Our findings suggest that chronic GVHD may be complicated with diffuse proliferative glomerulonephritis through unknown cellular immune mechanism.

Nephrotic syndrome (NS) is a rare complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). The cases of 2 patients who developed NS after receiving allo-HSCT for chronic myelogenous leukemia and acute lymphoblastic leukemia are described. In both cases, renal biopsy revealed membranous nephropathy (MN), and the patients achieved remission after treatment with prednisolone. Previously reported cases and our experience suggest that most NS patients show MN in histologic tests after allo-HSCT and that its development is related to graft-versus-host disease. Early treatment with steroids seems effective for resolving symptoms of NS and improving renal function.

Graft-versus-host disease (GVHD) is one of the most frequent complications that occur after hematopoietic stem cell transplantation (HSCT). Recently, renal involvement, including membranous nephropathy, focal segmental glomerulosclerosis, and minimal change disease, has been described as a manifestation of chronic GVHD. This case report describes a patient who developed antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis after HSCT. Following preparation with chemotherapy, a 29-year-old man with chronic myeloid leukemia underwent allogenic peripheral blood stem cell (PBSC) transplantation, after which first acute and then chronic GVHD developed. Treatment with prednisone resulted in improvement in the patient's GVHD. After the termination of steroid therapy and about 10 months after PBSC transplantation, nephritic syndrome appeared and the patient's serum creatinine value increased to 1.7 mg/dL. Laboratory evaluation revealed perinuclear antineutrophilic cytoplasmic antibody (p-ANCA) in the serum. Histological examination of renal biopsy tissue showed focal segmental proliferative glomerulonephritis with glomerulosclerosis in 20% of available glomeruli, large cellular crescents in 6% of glomeruli, and no staining of immunoglobulins or complement along the capillary walls. Electron microscopy revealed no immune deposits. After treatment with prednisone 60 mg/d, diltiazem 120 mg/d, and enalapril 10 mg/d, the proteinuria gradually decreased, and p-ANCA was undetectable. These findings suggest that in this patient the ANCA-associated glomerulonephritis was associated with renal involvement that occurred during the course of chronic GVHD.
