RT Journal Article SR Electronic T1 Concomitant Clostridium difficile colitis and cytomegalovirus colitis in an immunocompetent elderly female JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2012007273 DO 10.1136/bcr-2012-007273 VO 2012 A1 Maria Kurtz A1 Mackenzie Morgan YR 2012 UL http://casereports.bmj.com/content/2012/bcr-2012-007273.abstract AB A 78-year-old Japanese woman with diarrhoea and abdominal pain was admitted for PCR test (PCR)-proven Clostridium difficile colitis. The patient's symptoms persisted despite multiple courses of antibiotics including intravenous metronidazole, oral  vancomycin and oral fidaxomicin. She underwent a stool transplant without improvement. Biopsies from a colonoscopy revealed concomitant cytomegalovirus (CMV) infection. The patient was immediately started on intravenous ganciclovir. Unfortunately, she developed sepsis secondary to colitis, and underwent definitive treatment with a total colectomy. Although CMV is a rare colonic pathogen in the immunocompetent patient, it should be considered in patients with severe or refractory C difficile colitis.
