Abstract

An immunoglobulin G (IgG) antibody avidity assay which uses protein-denaturing agents and a modification of an enzyme-linked immunosorbent assay have been investigated for their usefulness in distinguishing primary genital herpes simplex virus (HSV) infections from nonprimary infections. Forty-nine serum specimens from patients with primary, recurrent, and nonprimary first-episode genital herpes were studied. The clearest separation was obtained with 6 M urea treatment, giving mean avidity indices of 0.398 for sera < or = 100 days after the infection and 0.879 for sera > 100 days after the infection (P < 0.001). No significant difference in avidity indices was observed between the recurrent and nonprimary first-episode infections. Determination of the avidity of HSV-specific IgG will improve the diagnostic potential of HSV serology.

摘要

一种使用蛋白质变性剂的免疫球蛋白G(IgG)抗体亲和力测定法以及酶联免疫吸附测定法的改良方法,已被研究其在区分原发性生殖器单纯疱疹病毒(HSV)感染与非原发性感染方面的实用性。对49例原发性、复发性和非原发性初发性生殖器疱疹患者的血清标本进行了研究。用6M尿素处理时得到了最清晰的区分,感染后≤100天的血清平均亲和力指数为0.398,感染后>100天的血清平均亲和力指数为0.879(P<0.001)。复发性感染和非原发性初发性感染之间的亲和力指数没有显著差异。测定HSV特异性IgG的亲和力将提高HSV血清学的诊断潜力。
