Clinically apparent cytomegalovirus (CMV) colitis in adults is most frequently found in immunosuppressed patients, although sporadic cases have been reported in apparently immunocompetent subjects.
We hypothesized that, since most patients with clinically apparent CMV colitis are hospitalized, the prevalence of CMV colitis in patients undergoing colonoscopy in outpatient endoscopy centers would be low. We also endeavored to determine whether in outpatient settings immunocompetent and immunosuppressed patients present with different manifestations.
