A Case of Cytomegalovirus and Pseudomembranous Colitis in an Immunocompetent Adult

Cytomegalovirus (CMV) colitis is a rare event that has been described mainly in immunocompromised patients who are on immunosuppressive medication or they have HIV infection. CMV colitis manifesting in an immunocompetent host is exceedingly rare, but this has occasionally been described in pregnant patients and patients with chronic renal failure. Pseudomembranous colitis (PMC) is known to develop with long-term antibiotic administration and it is caused by the abnormal overgrowth of toxin-producing Clostridium difficile that colonize the large bowel. Appropriate diagnostic testing and early treatment may avert morbidity and mortality. A case of the simultaneous occurrence of cytomegalovirus and Clostridium difficile colitis in an immunocompetent adult has not yet been reported in the Koran medical literature. We report here on a case of the simultaneous occurrence of cytomegalovirus and Clostridium diffiicle colitis in an immunocompetent Korean adult.
