采用巨细胞病毒（ＣＭＶ）单克隆抗体对４４例肾移植患者外周血白细胞进行了ＣＭＶ抗原检测，同时进行了血清学ＥＬＩＳＡ检测和临床症状观察。结果显示：２８例活动性ＣＭＶ感染患者中，２６例抗原检测阳性；１６例无活动性ＣＭＶ感染患者中，仅１例抗原检测阳性；抗原阳性白细胞数与ＣＭＶ特异性的临床症状相一致。认为单克隆抗体检测外周血白细胞中ＣＭＶ抗原的方法是早期、快速诊断活动性ＣＭＶ感染的较理想方法。
Cytomegalovirus (CMV) monoclonal antibody was used to detect the CMV antigen in 44 patients with renal allograft and serological ELISA and clinical symptom were also performed. The results showed that of the 28 patients with active CMV infection, 26 were positive for antigens. Only 1 of the 16 patients with active CMV infection was positive for antigens. The number of antigen-positive leukocytes was consistent with the CMV-specific clinical symptoms. The idea that monoclonal antibodies detect CMV antigens in peripheral white blood cells is an ideal method for early diagnosis of active CMV infection.
