Abstract
AbstractTo explore the impacts of cytomegalovirus (CMV) infection and antiviral treatment (AVT) on native liver survival (NLS) in biliary atresia (BA) infants. This retrospective cohort study included infants diagnosed as BA between January 2015 and December 2021 at Hunan Children's Hospital. CMV infection was defined by DNA polymerase chain reaction alone (DNA data set) and combination of DNA and immunoglobulin M (CMV data set). In the DNA data set of 330 patients, 234 patients (70.9%) survived with their native liver in 2 years, with 113 (73.9%) in the DNA− cohort, 70 (65.4%) in the DNA+ and AVT− cohort and 51 (72.9%) in the DNA+ and AVT+ cohort, without significant differences by log‐rank tests. In patients administrated between 2015 and March 2019, there were 206 evaluable patients in the DNA data set, with rates of 5‐year NLS of 68.3% in the DNA− cohort, similar to that in the DNA+ and AVT+ cohort (62.2%, p = 0.546), but significantly higher than that in the DNA+ and AVT− cohort (51.4%, p = 0.031). Similar trends were also observed in the CMV data set, although statistically insignificant. CMV infection before or on the day of HPE can reduce the rate of 5‐year NLS and AVT was recommended for CMV‐infected BA infants.
