[An analysis of CMV infection in 115 cases with viral hepatitis].
To study prevalence of cytomegalovirus (CMV) infection in patients with viral hepatitis and its clinical characteristics, serum anti-CMV-IgM was detected in 6411 hospitalized hepatitis cases, and clinical symptoms, signs and liver function in 115 cases with CMV infection were compared with 192 cases of non-CMV infection. Results showed a CMV infection rate of 1.79% in them with an average age of 33.6 years, a sex ratio of 2.13, and dual superinfection with CMV and hepatitis accounting for 44.74%, and triple and quadruple superinfection for 47.37% and 7.89%, respectively. Proportion of those with fever, digestive symptoms, hepatomegaly, changes of gallbladder in ultra sound scan, rising activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyltransferase (gamma-GT) were more, and duration of hospitalization longer in the cases with CMV infection. It suggests that CMV can be found in the cases with viral hepatitis, most in a form of dual or multiple infection, and it can aggravate hepatitis.
