    Abstract Infections are a major cause of morbidity and can result in mortality in long-term survivors after allogeneic hematopoietic cell transplantation. Chronic graft-versus-host disease and delayed immune reconstitution are recognized risk factors. Different strategies must be utilized depending on the individual patient's situation but include prolonged antimicrobial prophylaxis and vaccination. Some important infections due to pathogens preventable by vaccination are pneumococci, influenza, varicella-zoster virus, and SARS-CoV-2. Despite the fact that such recommendations have been in place for decades, implementation of these recommendations has been reported to be poor.

    Abstract Purpose of review: The aim of this review is to discuss recent developments regarding the impact of cytomegalovirus (CMV) serological status of hematopoietic stem cell transplantation recipients and their donors on transplant outcome.
    Recent findings: CMV seropositivity of the recipient is still a negative factor for transplant outcome. The use of a CMV seropositive donor has a negative impact on survival in patients receiving unrelated but not human leukocyte antigen-identical sibling grafts. In CMV seropositive patients, the donor serological status influences outcome in patients receiving unrelated donor grafts after myeloablative but not reduced-intensity conditioning. Early CMV replication reduces the risk for leukemia relapse but does not improve survival. The use of leukocyte depleted blood products is sufficient to prevent primary CMV infection.
    Summary: Despite major advances in management of CMV infections, CMV serologic status remains an important risk factor for transplant-related complications and mortality after allogeneic hematopoietic stem cell transplantation.

    Abstract In allogeneic hematopoietic cell transplantation (allo-HSCT), both virus-specific T cells and leukemia-specific T cells need to be reconstituted to protect patients from virus infections and primary disease relapse. Cytomegalovirus (CMV) infection remains an important cause of morbidity and mortality after allo-HSCT. Emerging data indicate that CMV reactivation is associated with reduced risk of leukemia relapse in patients with acute myeloid leukemia (AML) undergoing allo-HSCT. In a cohort of 24 WT1+ AML patients during the first year following HSCT, CMV specific CD8+ T cells (CMV-CTL) reconstituted much faster than WT1-specific CD8+ T cell (WT1-CTL) after allo-SCT. Moreover, CMV-CTL expressed lower levels of exhaustion markers and were more functional as identified by production of IFN-γ/TNF-α and expression of Eomes/T-bet. Interestingly, our patients with CMV reactivation presented higher frequency of CMV-CTL, lower levels of Eomes+T-bet- and higher levels of Eomes+T-bet+ expression in response to WT1 and CMV pp65 antigen during the first year after transplantation as compared to patients without CMV reactivation. Kinetics of CMV-CTL and WT1-CTL after transplantation might be associated with measurable residual disease and later leukemia relapse. Our results support that CMV reactivation, aside from the CMV-CTL reconstitution, could influence WT1-CTL reconstitution after allo-HSCT, thus potentially contributing to the remission/relapse of AML.
