Objectives: Cytomegalovirus infections cause the most frequent infection after solid-organ transplant. While Cytomegalovirus prophylaxis is established in high-risk patients (donor+/ recipient-), data on Cytomegalovirus prophylaxis in other serostatus constellation are rare. The aim of this study was to evaluate the influence of Cytomegalovirus treatment strategy after a liver transplant (preemptive therapy vs general prophylaxis) in the largest group of patients: Cytomegalovirus seropositive donor and recipient.
Materials and methods: Forty-seven seropositive recipients of seropositive donor liver transplants (D+/R+, 2005-2012) were included in this retrospective study. Twenty-one patients received oral valganciclovir as Cytomegalovirus prophylaxis 100 days after transplant. Cytomegalovirus infection and Cytomegalovirus disease were monitored during the first 6 months.
Results: A Cytomegalovirus infection could be detected in 4 out of 47 patients (8.5%), including Cytomegalovirus disease in 2 patients (Cytomegalovirus pneumonia and Cytomegalovirus-CNS disease). Three of these patients received no Cytomegalovirus prophylaxis (P = .408). Eight patients developed a graft failure; this occurred more frequently among patients without Cytomegalovirus prophylaxis (P = .044). Patients receiving Cytomegalovirus prophylaxis more often developed leukopenia. No difference was seen regarding the number of platelets, hemoglobin, and creatinine.
Conclusions: Cytomegalovirus prophylaxis can minimize the risk of Cytomegalovirus reactivation and graft failure. However, disadvantages of the prophylaxis as leukopenia should be considered.
