An HIV-infected Patient with Confirmed Overlapping Complications of Severe Amebic Colitis and CMV Enteritis

We herein report a case of simultaneous amebic colitis and cytomegalovirus (CMV) enteritis in an HIV-infected patient. The patient was a 40-year-old man who developed bloody stool and diarrhea. We diagnosed him with severe amebic colitis associated with HIV infection and administered metronidazole. While his symptoms began to improve, the patient then developed CMV enteritis. We administered ganciclovir, and his symptoms improved. However, despite control of the infection, stenosis of the descending colon caused intestinal obstruction, and colostomy was performed. This case shows the importance of considering the possibility of simultaneous infection when gastrointestinal symptoms appear in people infected with HIV.
