摘　　要：目的回顾性分析抢先治疗异基因造血干细胞移植（allo—HSCT）后巨细胞病毒（CMV）感染的临床意义。方法allo—HSCT治疗的患者103例，采用荧光定量PCR法监测CMV—DNA，并根据其结果抢先治疗CMV相关疾病，分析抢先治疗对于阻止CMV血症发展为CMV相关疾病的意义。结果103例患者中检测出63例次（51例）CMV—DNA阳性，CMV血症发生率为49．5％，经抢先治疗19例发生CMV相关疾病，发生率为18．4％。60例次CMV血症经更昔洛韦和（或）膦甲酸治疗转阴，1例不可评价疗效，治疗的总有效率为96．8％（60／62）。CMV相关疾病的治疗总有效率为89．5％（17／19），2例患者因CMV相关肺炎伴急性GVHD而死亡，CMV相关疾病的直接死亡率为1．9％（2／103）。结论在不进行预防性治疗的前提下，CMV血症和CMV相关疾病发生率未见升高。抢先治疗能有效阻止大部分CMV血症患者发病，并能有效控制CMV相关疾病的进展。Objective To retrospectively analyze the effect of preemptive treatment on cytomegalovirus （CMV） infection in patients receiving allogeneic hematopoietic stem cell transplantation （allo-HSCT）. Methods The data of one hundred and three patients who underwent allo-HSCT with preemptive treatment to prevent CMV associated diseases were retrospectively analyzed. Fluorescence quantitative PCR was used to detect CMV-DNA. The incidences of CMV viremia and CMV associated diseases were analyzed. Results CMV viremia was confirmed 63 times in 51 of the 103 patients. The incidence of CMV viremia was 49.5% and the median time of onset was 40 days after transplantation. All the patients with CMV viremia received preemptive antiviral therapy and 19 of them developed CMV associated diseases, including 14 hemorrhagic cystitis, 3 CMV associated pneumonia and 2 CMV associated enteritis. The total incidence of CMV associated diseases was 18. 4%. After treatment with ganciclovir and/or foscarnet, 60 of the 63 times of CMV viremia disappeared. One patient was not included in the analysis because he died of intracranial hemorrhage and GVHD only 3 days after the treatment. The total response rate was 96. 8% （60/62）. The remaining two cases who did not respond to treatment died of CMV associated pneumonia in combination with acute GVHD. The direct mortality rate of CMV infection was 1.9% （2/103）. Conclusion The incidences of CMV viremia and CMV associated diseases do not increase in patients receiving preemptive therapy as compared with those receiving prophylaxis therapy. Preemptive treatment can not only prevent the progression of CMV viremia to CMV associated diseases in majority of the cases but also control CMV associated diseases effectively.
