To analyze the clinical characteristics of cytomegalovirus(CMV) infection after allogenic hematopoietic stem cell transplantation(allo-HSCT) and the effect of preemptive therapy.A total of 134 patients who underwent allo-HSCT from March 2010 to March 2015 in the Department of Hematology of our hospital were enrolled in this study. The CMV infection rate, the median time of CMV infection occurence, and the risk factors for CMV infection after allo-HSCT, the response rate of preemptive treatment and the median time of CMV-DNA turning negative were analyzed. Five-year overall survival rate was compared between the patients with or without CMV infection.The incidence of CMV viremia was 55.2％(74／134), and the median time for the CMV with CMV-DNA positive for the first time was 34 days(14-283) after allo-HSCT．Both univariate and multivariate analysis showed that the thymoglobulin(ATG) used in conditioning regimen and Ⅱ-Ⅳ grade of aGVHD were the risk factors for CMV viremia. After preemptive treatment the 85.1% of patient with CMV viremia turned negative, and the median time of CMV-DNA turning negative were 15 days(5-82), only 2 patients died of CMV pneumonia. Five-year overall survival rate of the patients with or wihout CMV viremia was 49% and 66.3% respectively, and the difference between the 2 groups was significant(P=0.041）.The ATG used in conditioning regimen and Ⅱ-Ⅳ grade of aGVHD may increase the incidence of CMV infection after allo-HSCT, and the preemptive thrapy can effectively prevent the CMV viremia turning to CMV disease. |
