摘要
Background:The frequency of cytomegalovirus (CMV) colitis in steroid-refractory inflammatory bowel disease has been reported to range from 15.8% to 34.0%. Infected patients are more likely to become hospitalized, have longer lengths of stay, and higher mortality rates. Current data are limited to small scale studies and showed conflicting result regarding the role of antiviral therapy.Aims:(1) To investigate the role of antiviral treatment in ulcerative colitis (UC) patients with CMV infection. (2) To investigate the role of viremia in the outcomes of these patients.Materials and Methods:The Cleveland Clinic pathology database identified 1478 patients who had colon biopsy and were tested for CMV during 1990 to 2013. After inclusion and exclusion, 41 UC patients were selected. Among them, 24 (58.5%) received treatment, 17 (41.5%) did not. A total of 14 demographic data and 4 clinical outcomes (surgery free survival, hospitalization, rehospitalization, and mortality) were compared between treated and nontreated patients. The same outcomes were also compared in patients who received treatment based on their viremia status.Results:All demographic variables are similar between those treated and nontreated groups. Antiviral therapy significantly improved the surgery free survival within 30 days, and lasted 70 months (P<0.01). In contrast, hospitalization, rehospitalization, and mortality were comparable (P>0.05). No significant difference was observed in any of the clinical outcomes based on viremia status.Conclusions:Our small scale study demonstrates that antiviral treatment for colonic CMV infection significantly improves the surgery free survival short-term and long-term in patients with UC.
