Intractable diarrhea and melena in an AIDS patient

A young Arab male, clinically suspected to have ulcerative colitis, was operated upon for fulminant intractable diarrhea with melena. The colon showed severe necrotizing and hemorrhagic colitis which was attributed to an opportunistic infection, viz cytomegalovirus infection. The patient's immunocompromised state was a consequence of AIDS, proved by ELISA and Western Blot test. He subsequently developed multiple brain abscesses and succumbed to uncontrolled infection.
