cytomegalovirus

Objective. To perform genotyping of cytomegalovirus (CMV) phosphotransferase UL97 and investigate mutations associated with ganciclovir/valganciclovir (GCV/VGCV) resistance in children after allogeneic hematopoietic stem cell transplantation (HSCT) with confirmed CMV infection. Materials and Methods. This single-center prospective study was conducted from January 2020 to December 2021 and enrolled allogeneic HSCT recipients under 18 years of age with confirmed CMV infection. In case of possible GCV resistance, molecular genotyping with Sanger sequencing was performed.

Objective. To identify mutations in UL97 gene associated with antiviral drug resistance in recipients of allogeneic hematopoietic stem cells transplants (allo-HSCT). Materials and Methods. A total of 9 HCMV DNA samples were studied. These samples were received from the blood of 8 allo-HSCT recipients who were infected with HCMV and undergoing treatment at NMRC of Hematology (Russia) over the period of 2016 to 2017. Sanger sequencing was used to find mutations.
