巨细胞病毒抗原检测在肾移植中的临床应用
【摘要】 目的 建立一种新的快速诊断巨细胞病毒(CMV)感染的方法并初步用于肾移植受者。方法 采用抗CMV抗原的单克隆抗体，运用免疫组化链菌素-生物素标记法对外周血白细胞核中CMV抗原(即刻早期抗原和早期抗原)进行染色，诊断CMV感染。结果 共检测肾移植受者72例，CMV活动性感染率为47%(34/72)，CMV病发病为18%(13/72)。CMV抗原阳性细胞数在CMV活动性感染者中平均为11.5/5万WBC，在CMV病者为20.5±17.8/5万WBC。同时检测10名健康人，结果均为阴性。结论 该法具有快速、简便、成本低等优点，且能达到定量检测的目的，可用于临床对CMV感染的早期快速诊断。【关键词】巨细胞病毒抗原 肾移植 免疫组化链菌素-生物素标记

【Abstract】Objective to establish a new method for the diagnosis of human cytomegalovirus(HCMV) infection and disease in renal transplant recipients.Methods labeled streptavidin biotin (LSAB)method with CMV monoclonal antibody was used to detect CMV antigen in peripher、al blood leukocytes.Results CMV antigen positive cells were counted in every 5.0×104 wbc. 72 renal transplant recipients wereinvestigated. The rate of CMV active infection was 47% (34/72) and the average count of CMV antigen positive cells was 11.5/5.0×104 WBC. The incidence of CMV disease was 18% (13/72) with a CMV antigen value of 20.5±17.8/5.0×104 WBC. 10 healthy people were also studied and the results of CMV antigen were negative.Conclusions This method provides a rapid, accurate and low cost approach to the diagnosis of CMV infection and can be quantified easily. ......
