Background and Aim: Cytomegalovirus (CMV) infection is a serious complication following solid organ and bone marrow transplantation (BMT). CMV affects multiple organs and results in considerable morbidity and prolonged hospitalization. But the clinical feature of upper GI lesions in CMV infection after BMT remains unclear. Detection of CMV antigen in peripheral blood leukocytes with immunohistochemical technique (antigenemia) is the most reliable screening method for CMV infection. The antigenemia is, however, not sensitive enough in some cases. The aim of this study is to investigate the clinical significance of upper GI lesions in CMV infection. Patients and Methods: We performed endoscopic examination of the upper GI tract in 47 patients 20 to 70 days after allogeneic BMT from December 1992 to November 1997. Biopsy specimens, taken each from esophagus, stomach body and antrum, and duodenum, were assayed for CMV antigen with immunohistochemical technique. Results: CMV infection was revealed in the upper GI tract in 9 patients. The endoscopic findings of the affected lesions were characteristic erosions surrounded by redness in the stomach and duodenum, map-like redness in the duodenum, and ulcer in the esophagus. Stomach was involved in all cases (9/9, 100%), but duodenum (4/9, 44%) and esophagus (2/9, 22%) were less frequently infected. In 3 patients, CMV antigen was detected in the upper GI tract before antigenemia turned positive. Conclusion: The endoscopic examination of upper GI tract is a useful screening method for CMV infection following allogeneic BMT.
