Early selection of a new UL97 mutant with a severe defect of ganciclovir phosphorylation after valaciclovir prophylaxis and short-term ganciclovir therapy in a renal transplant recipient.

چکیده
We describe the emergence of a new ganciclovir resistance mutation in the UL97 gene of human cytomegalovirus, deletion of codon 601, after valaciclovir and short-term ganciclovir therapy following kidney transplantation. Its role in ganciclovir resistance was supported by decreased ganciclovir phosphorylation in a recombinant vaccinia virus system.

Incidence of ganciclovir resistance in CMV-positive renal transplant recipients and its association with UL97 gene mutations
Human cytomegalovirus (CMV) remains the most common infection affecting organ transplant recipients. Despite advances in the prophylaxis and acute treatment of CMV, it remains an important pathogen affecting the short- and long-term clinical outcome of solid organ transplant recipient. The emergence of CMV resistance in a patient reduces the clinical efficacy of antiviral therapy, complicates t...

Ganciclovir susceptibilities and UL97 sequences were analyzed in 20 cytomegalovirus (CMV) isolates recovered from 15 bone marrow transplant recipients with active CMV infection after prophylaxis with acyclovir (group I; 12 isolates) or after acyclovir prophylaxis followed by ganciclovir therapy (group II; 8 isolates). All group I isolates were susceptible to ganciclovir. Five group II isolates ...

Abstract Background: Lymph proliferative is the popular disease after organ transplant. The prophylactic use of ganciclovir is one of the solutions in preventing this disease. In this study, the effect of prophylaxis ganciclovir in the prevention of PTLD in children was examined. Materials and Methods: In this cohort study, case group of children who had undergone a liver transplant in January ...
