Complement independent neutralizing antibody assays (CINA) have been used in seroepidemiologic studies and in diagnostic laboratories to distinguish between antibodies to herpes simplex virus types 1 (HSV-1) and 2 (HSV-2). The accuracy of CINA has not been rigorously tested against protein-specific typing assays, such as Western blot.
To determine the ability of CINA to identify HSV-2 antibodies alone or in the presence of HSV-1 antibodies.
Sera from randomly selected women at the Seattle King County Sexually Transmitted Disease Clinic were tested by CINA and Western blot.
Of 521 women tested, 81% had HSV antibodies by Western blot and 76% had neutralizing antibodies. Of 220 sera with HSV-2 antibodies by Western blot, 106 (48%) were serotyped correctly by CINA. Of the women studied, 140 (27%) had type-indeterminate neutralizing antibodies; 55 of these sera (39%) had antibody only to HSV-1 by Western blot.
The seroprevalence of HSV-2 in an STD clinic population was seriously underestimated by CINA.
补体非依赖中和抗体检测(CINA)已用于血清流行病学研究及诊断实验室,以区分抗1型单纯疱疹病毒(HSV-1)和2型单纯疱疹病毒(HSV-2)的抗体。CINA的准确性尚未与蛋白质特异性分型检测(如免疫印迹法)进行严格对比测试。
确定CINA单独识别HSV-2抗体或在存在HSV-1抗体时识别HSV-2抗体的能力。
对西雅图金县性传播疾病诊所随机选取的女性血清进行CINA和免疫印迹法检测。
在接受检测的521名女性中,免疫印迹法显示81%的女性有HSV抗体,76%的女性有中和抗体。在免疫印迹法检测出有HSV-2抗体的220份血清中,CINA正确分型106份(48%)。在研究的女性中,140名(27%)有无法确定型别的中和抗体;其中55份血清(39%)免疫印迹法显示仅对HSV-1有抗体。
CINA严重低估了性病诊所人群中HSV-2的血清流行率。
