Protein-losing gastropathy associated with cytomegalovirus: a rare and late complication of allogeneic bone marrow transplantation.

A 36-year-old women with chronic myelogenous leukemia in first chronic phase received a bone marrow transplant from her HLA-identical brother. The preparatory regimen consisted of total body irradiation (10 Gy) and cyclophosphamide (60 mg/kg for 2 days). Full engraftment was achieved and the woman was monitored as an outpatient after discharge from hospital on day 35. One year after BMT, while she was on cyclosporin A and steroids because of chronic graft-versus-host disease, the patient developed protein-losing gastropathy associated with cytomegalovirus infection (with no gastrointestinal symptoms), which regressed spontaneously in 4 weeks.
