Cytomegalovirus colitis in a human immunodeficiency virus-positive patient with a normal CD4 count.

Cytomegalovirus (CMV) is the most common cause of life-threatening opportunistic viral infection in patients with the human immunodeficiency virus (HIV) disease. The colon is a well-known target organ for CMV in these patients. CMV colitis is commonly associated with the later stages of HIV disease but rarely occurs in early HIV infection. In this study, an unusual case of CMV colitis in a 22-year-old man who had a normal CD4 count but at the same time was found to be HIV positive with a moderately high viral load is reported.
