METHODS: Eighty cases who had undergone renal transplantation were randomly divided into 2 groups:① preemptive therapy group (n=40), who were given ganciclovir (GCV, 250 mg/d) once at least 1 CMVPP65 positive cell per 2.0×105 PBL till the antigenemia became negative.② Control group (n=40), who were given universal twoweekprophylaxis with GCV (250 mg/d) beginning at the 3rd week after transplantation. A 3month followup was conducted and the efficacy and costeffectiveness of the 2 groups were compared.

将尸肾移植后患者80例分为两组：①早期治疗组（n=40），即在术后若监测到CMVPP65抗原血症阳性，则给予更昔洛韦（250 mg/d）治疗，直至抗原血症转阴；②对照组（n=40），所有患者从移植后第3周开始均给予更昔洛韦（250 mg/ d）治疗，持续2 wk，随访时间3 mo，观察两组对CMV疾病的预防效果。
