ABSTRACT
Objective To analyze the clinical features,clinical prognosis and predictive factors of ulcerative colitis (UC) complicated with cytomegalovirus (CMV) infection.Methods From May 2004 to November 2014,120 hospitalized patients diagnosed as UC and screened for CMV infection were enrolled.A total of 31 patients with moderate to severe UC accompanied by CMV infection were screened out.Demographics,clinical features,endoscopic appearance and treatment of patients with UC complicated with CMV infection were analyzed,and compared with 60 moderate to severe UC patients without CMV infection at the same period of hospitalization.Mann Whitney U test was performed for statistical analysis.Logistic regression analysis was used to analyze risk factors of UC complicated with CMV infection.Results Among 120 patients with UC,29 were mild or in remission period,whose CMV screening tests were all negative.Ninety-one were moderate to severe,31 patients (34.1 %) of them had CMV infection,and 20 of 31 patients were steroid-refractory.Among the 31 patients with UC complicated with CMV infection,median age was 39 years (22 years,51 years),median disease duration was 24.0 months (6.0 months,42.0 months) which was shorter than that of patients without CMV infection (36.0 months (13.5 months,84.0 months)),and the difference was statistically significant (U=639.5,P=0.015).A total of 23 patients (74.2%) had extensive colitis and 26 patients (83.9%) had history of severe colitis.A total of 29 patients (93.5%) had history of corticosteroids treatment,12 patients (38.7%) had history of immunosuppressive agents treatment,and six patients (19.4 %) had history of infliximab treatment.Compared with UC patients without CMV infection,fever,abdominal pain and weight loss were more common in UC patients with CMV infection.Five CMV-infected patients had mild liver dysfunction.Endoscopic appearance was longitudinal ulceration,irregular ulceration,large deep ulceration,punchedout ulceration and worm-like ulceration.Among the 25 CMV-infected patients who were treated with corticosteroids,11 patients (44.0%) had no response.Among the 39 CMV-negative patients who were treated with corticosteroids,eight patients (20.5%) had no response.The rate of patients who needed rescue therapy of the former was higher than that of the latter,and the difference was statistically significant (x2 =4.026,P=0.045).The results of multivariate Logistic regression analysis showed that hemoglobin over 100 g/L(OR=0.144,95% confidence interval (CI) 0.040 to 0.516,P=0.003) was a protective factor of CMV infection,however corticosteroids use within a month before the onset (OR=8.946,95%oCI 2.459 to 32.541,P=0.001) was a risk factor.Conclusions UC patients treated with corticosteroids and immunomodulator therapy may predispose UC patients to CMV infection,on the other hand,CMV infection can exacerbate the severity of UC.CMV infection should be screened and monitored in UC patients,and anti viral therapy should be taken in time in case of CMV infection.
