Safety of Valganciclovir 450 mg 3 Times Weekly for Cytomegalovirus Prophylaxis in Solid Organ Transplant Recipients Requiring Hemodialysis
OPEN FORUM INFECTIOUS DISEASES(2021)
摘要
Background. Valganciclovir is the most commonly used antiviral for cytomegalovirus (CMV) prophylaxis in solid organ transplant recipients. However, there are limited clinical outcomes-supported data available to guide valganciclovir dosing in patients on hemodialysis (HD). This study aimed to assess the safety of our institution's current dosing strategy of valgancidovir 450 mg 3 times weekly post-HD. Methods. This was a single-center retrospective review of all adult nonkidney transplant recipients between May 2016 and June 2018. Patients with end-stage renal disease requiring HD for >28 days posttransplant receiving valganciclovir 450 mg 3 times weekly post-HD were matched with non-I ID patients receiving valganciclovir prophylaxis dosed per renal function. The primary endpoints were incidence of leukopenia, neutropenia, and thrombocytopenia while on valganciclovir prophylaxis. Results. A total of 465 nonkidney transplants were performed during the study period, with 37 patients included in the HD group who were matched to 111 control patients in the non-HD group. Liver transplant recipients comprised 84% and 72% of each group, with none being CMV D+/R-. The rates of leukopenia (51.4% vs 51.4%, P = 1.00), severe neutropenia (absolute neutrophil count <500 cells/pL, 15.8% vs 14.0%, P = .85), and thrombocytopenia (24.3% vs 20.7%, P = .64) were similar in both HD and non-HD groups. There were no cases of CMV infection while on valganciclovir prophylaxis in either group. Conclusions. Valganciclovir 450 mg 3 times weekly was found to have similar rates of leukopenia, neutropenia, thrombocytopenia, and CMV infection in comparison to valganciclovir dosed per renal function in non-I ID transplant recipients.
