A foal with primary severe combined immunodeficiency, diagnosed within the first two weeks of life, was maintained with its dam in semi-isolation. The foal received continuous prophylactic antibiotic therapy, plasma from a sibling hyperimmunised with equine adenovirus vaccine, and intensive general nursing care. A full sibling female was selected as a bone marrow donor on the basis of red blood cell cross-matching and mixed lymphocyte reactions. Cyclophosphamide was given before two bone marrow transfusions at 35 and 73 days of age. To prevent graft versus host disease graft versus host disease the foal was maintained on methotrexate therapy. Reconstitution was not achieved nor were there signs of graft versus host disease. The foal died suddenly four days after the second bone marrow transfer when 77 days old. It had remained clinically free of any life threatening infectious disease and at necropsy a remarkable degree of freedom from infectious disease was confirmed. The most notable necropsy findings were bilateral nephrosis and myocardial degeneration and fibrosis. The likely cause of death was an electrolyte imbalance, particularly hypokalaemia, which secondarily affected the myocardium. Renal toxicity caused by the cytotoxic drugs, especially cyclophosphamide, may have contributed to the electrolyte imbalance.

A 44-year-old man who received allogenic hematopoietic stem cell transplantation after being diagnosed with acute myeloid leukemia developed nephrosis when the dose of tacrolimus was tapered. A renal biopsy showed the granular deposition of immunoglobulin G in the glomerular basement membrane and subepithelial electron-dense deposits, crescent formation, C4d-positive staining of the peritubular capillary, and subendothelial swelling, suggesting that the main pathological diagnosis was membranous nephropathy and that chronic graft-versus-host disease played a role in the etiology of nephrosis. We herein report a case of membranous nephropathy with various pathological findings. C4d deposition suggests complement activation and the involvement of humoral factors.
