Effects of preoperative hepatitis B virus infection, hepatitis C virus infection, and coinfection on the development of new‐onset diabetes after kidney transplantation

摘要

Abstract Background The effects of preoperative hepatitis B virus (HBV) infection, hepatitis C virus (HCV) infection, and HBV plus HCV coinfection on the development of new‐onset diabetes after transplantation (NODAT) remain unexplored in kidney transplant recipients (KTRs). This study examined the association between preoperative viral status (i.e., HBV, HCV, and HBC?+?HCV infection) and incident NODAT in a large population of Chinese KTRs. Methods This population‐based retrospective cohort study enrolled 557 subjects who underwent kidney transplantation between 1993 and 2014 at Zhongshan Hospital. Pre‐, peri‐, and postoperative data were extracted and analyzed. Viral status was defined by serological results for hepatitis B surface antigen and anti‐HCV antibody. The cumulative incidence of NODAT was compared across four groups of KTRs with different viral status. Multivariate Cox regression models were used to estimate the effects of HBV, HCV, and HBC?+?HCV infection on incident NODAT after adjusting for important confounders. Results Patients seropositive for HCV (both HCV monoinfection and HBC?+?HCV coinfection) had a significantly higher cumulative incidence of NODAT than KTRs who were not infected with HCV ( P ??0.05 for both). However, only HCV infection alone was found to be a risk factor for NODAT, increasing the NODAT risk 3.03‐fold (95% confidence interval 1.77‐5.18; P ??0.001). There was no independent correlation between HBV infection (alone or combined with HCV) and incident NODAT in KTRs. Conclusions Preoperative HCV infection significantly increased the risk of NODAT in Chinese KTRs, whereas HBV infection and HBC?+?HCV coinfection were not correlated with NODAT development.
