title: Cytomegalovirus colitis in patients without inflammatory bowel disease: a single center study.
abstract: OBJECTIVE
  Cytomegalovirus (CMV) aggravates preexisting inflammatory bowel disease (IBD), and there are numerous reports of CMV colitis in IBD patients. However, little attention has been paid to CMV colitis in non-IBD patients. The aim was to determine the clinical manifestations, endoscopic appearance, and clinical course of CMV colitis in non-IBD patients.
  
  
  METHODS
  We reviewed medical records of patients diagnosed with CMV colitis based on immunohistochemical studies of biopsy specimens or surgical specimens between 1998 and 2009.
  
  
  RESULTS
  The medical records of 43 patients were reviewed. Subjects included individuals with AIDS, and those undergoing chemotherapy, steroid therapy, or transplantation, as well as individuals with other co-morbidities and individuals with no previous illnesses. Frequent symptoms were non-bloody diarrhea, abdominal pain, fever, and hematochezia. Macroscopically normal rectosigmoid mucosa was observed in eight of 21 patients who underwent full-length colonoscopy. Endoscopic findings were varied, and included macroscopically normal (n = 2), colitis alone (n = 12), ulcer alone (n = 5), and ulcer with colitis (n = 22). The ulcer margin was well-circumscribed in 12 of 21 patients. Thirty-six patients were administered antiviral agents and two patients died. All patients who were not treated with an antiviral agent recovered spontaneously while waiting for their biopsy results.
  
  
  CONCLUSIONS
  Colonoscopy is preferred to sigmoidoscopy for diagnosis of CMV colitis. Antiviral therapy should not be mandatory for a subset of patients with CMV colitis.
