The Clinical Impact of Ganciclovir Prophylaxis on the Occurrence of Bacteremia in Orthotopic Liver Transplant Recipients

Abstract

Background. Cytomegalovirus (CMV) infection or receipt of a CMV-seropositive donor liver has been shown to be an independent predictor of bacteremia in orthotopic liver transplant (OLT) recipients. However, prevention of CMV infection through use of intense CMV prophylaxis has not been examined to assess the impact on bacteremia in liver transplant recipients. Methods. We analyzed the impact of CMV prophylaxis on rates of bacteremia by examining 192 consecutive OLT recipients during a 2-year follow-up period. Results. There were 29 episodes of bacteremia. Univariate analysis of risk factors for bacteremia showed that invasive fungal disease, initial anti-lymphocyte immunosuppression, treatment for rejection, and use of solumedrol were significantly associated with increased risk. Receipt of ⩾14 days of ganciclovir prophylaxis (hazard ratio [HR], 0.40; 95% CI [confidence interval], 0.18–0.87; P = .02), end-to-end biliary anastomosis, and receipt of P = .0437). Conclusions. Among factors associated with bacteremia, use of prophylactic ganciclovir is independently associated with a significant reduction of bacteremia in OLT recipients.
