Kinetics of Cytomegalovirus Load Decrease in Solid‐Organ Transplant Recipients after Preemptive Therapy with Valganciclovir

The availability of valganciclovir (VGCV) has significantly simplified the treatment of human cytomegalovirus (HCMV) infection after solid-organ transplantation. We show that there was no difference in the kinetics of the decrease in HCMV load after preemptive therapy with VGCV in 22 solid-organ transplant recipients (T1/2=2.16 days), compared with that in 23 patients treated with intravenous ganciclovir (GCV) (T(1/2) = 1.73 days; P=.63). Preemptive therapy with VGCV provides control of HCMV replication that is comparable to that achieved with preemptive intravenous therapy with GCV.
