Dasatinib, a tyrosine kinase inhibitor, is widely used for patients with chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia. Although the drug has a potent immunosuppressive effect, infectious complications during dasatinib treatment have been reported rarely. We describe five patients who developed cytomegalovirus (CMV) colitis during dasatinib treatment, in whom the colitis was initially confused with other causes. The patients, three with chronic myeloid leukemia, and two with acute lymphoblastic leukemia, were diagnosed with CMV colitis based on endoscopic and histologic findings. The patients who examined blood CMV polymerase chain reaction were all positive. The patients received antiviral therapy in the form of either ganciclovir or valganciclovir, and the overall treatment outcome was fair. These cases suggest that physicians should consider the possibility of CMV reactivation when treating diarrhea and/or hematochezia in patients on dasatinib.

Infection of the retina by cytomegalovirus characterized by retinal necrosis, hemorrhage, vessel sheathing, and retinal edema. Cytomegalovirus retinitis is a major opportunistic infection in AIDS patients and can cause blindness.
A pyrimidine and thiazole derived ANTINEOPLASTIC AGENT and PROTEIN KINASE INHIBITOR of BCR-ABL KINASE. It is used in the treatment of patients with CHRONIC MYELOID LEUKEMIA who are resistant or intolerant to IMATINIB.
A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology.
