allogeneic hematopoietic stem cell transplantation

Cytomegalovirus after allogeneic hematopoietic stem cell transplantation: reactivation or reinfection?

Objective. To determine type of cytomegalovirus (CMV) infection (reactivation of a virus strain that was present before transplantation or re-infection with another virus strain) in allogeneic hematopoietic stem cell recipients by sequencing. Materials and Methods. Clinical and laboratory data of 179 recipients of allogeneic hematopoietic stem cells collected from 2014 to 2018 were analyzed for CMV DNA in clinical specimens before and after transplantation. A total of 14 patients (28 samples) were included in the study.

Mutations in the cytomegalovirus UL97 gene associated with ganciclovir resistance in recipients of allogeneic hematopoietic stem cell transplants

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.

Aetiology of hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation

Incidence, severity, and risk factors for hemorrhagic cystitis (HC) were assessed in 267 patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). HC was diagnosed in 14.6% (39 patients) within 1-139 days after allo-HSCT …
