    Abstract:
    INTRODUCTION: Cytomegalovirus (CMV) infections continue to cause significant morbidity and mortality in hematopoietic stem cell transplant (HSCT) recipients. Successful pre-emptive therapy in transplant patients depends on the availability of reliable diagnostic tests for CMV infections. The purpose of this retrospective study was to evaluate CMV DNA viral load, incidence of CMV disease and CMV seropositivity, risk factors and correlation between CMV DNA positivity and clinical course in HSCT patients. METHODS: Two hundred and twenty-five patients who underwent peripheral blood stem cell or bone marrow transplantation between June 2003 and April 2010 were included. A real-time polymerase chain reaction (RT-PCR) assay was used for CMV monitoring. RESULTS: Recipient median age was 42.5 years. CMV seropositivity was 95.6%. CMV DNA positivity determined by RT-PCR was 24.9% among the entire patient group. CMV DNA positivity with RT-PCR was found to be significantly higher in allogeneic transplant recipients than autologous transplant recipients (46.7% vs 14.0%; P < 0.0001). Gender, age, conditioning regimen, stem cell source, underlying disease and recipient and donor seropositivity (alone or paired) were not significant risk factors for CMV DNAemia. We did not observe any CMV end-organ disease. CONCLUSION: CMV DNAemia was significantly higher in allogeneic transplant recipients than in autologous transplant patients. End-organ disease could be prevented with appropriate pre-emptive therapy.
