摘要 目的探讨EBV感染单个核细胞的临床意义。方法应用荧光定量PCR方法检测38名传染性单核细胞增多症患儿发热7d内、起病1、3、6及9个月外周血单个核细胞(PBMC)及血浆中EBVDNA,应用酶联免疫方法检测血清EBVVCR-IgM,进行统计学分析。结果38例患者在EBV感染发病7d内,单个核细胞中EBVDNA检出阳性34例,EBVVCR-IgM阳性22例,二者差异有统计学意义(X^2=9.39,P〈0.01);血浆EBVDNA检出阳性16例,与EBV—VCR—IgM比较差异无统计学意义(P〉0.05),PBMC与血浆中EBV—DNA比较差异有统计学意义(X^2=16.05,P〈0.01)。起病后9个月仍有3例患儿单个核细胞中可检测到EBVDNA。结论EBV感染初期,检测外周血单个核细胞EBVDNA,可作为传染性单核细胞增多症早期、快速、敏感的诊断方法;EBV可长期存在于单个核细胞中,荧光定量PCR方法检测外周血单个核细胞EBVDNA亦可作为判断疗效及监测病情的一种有效手段。EBV感染患儿表现出多系统损伤可能与PBMc中EBV感染有关。
