Cytomegalovirus (CMV) infection is one of the common complications which can lead to significant morbidity and mortality in patients after allogeneic hematopoietic stem cell transplantation (HSCT). As the seroprevalence of CMV infection in Malaysia is high, this study aims to determine the prevalence of CMV infection in patients post HSCT and to evaluate the associated risk factors. Patients who underwent allogeneic HSCT in adult ward from 2008 to 2020 at a tertiary teaching hospital in Kuala Lumpur, Malaysia were studied retrospectively. They were followed up for a minimum of 100 days post-HSCT to determine the incidence of CMV infection. CMV infection was defined according to CMV Drug Development Forum 2014. Risk factors such as type of transplant, serostatus of donor and patients, age, gender, race, presence of graft versus host disease (GVHD) and underlying disease were included for analysis. A total of 112 patients were included. Forty (35.7) patients had CMV infection with median of onset recorded as 40 days (range 13–95 days). Only haplo-identical HSCT and presence of GVHD were identified as significant risk factors. Patients who had CMV infection had a lower median survival time although this was not statistically significant. The CMV infection rate was comparable with previous reports in Asia and as expected, higher than the western countries. Therefore, vigilant monitoring of CMV infection should be implemented especially in patients who had haplo-identical HSCT and acute GVHD. © 2023, The Author(s), under exclusive licence to Indian Society of Hematology and Blood Transfusion.
