Low avidity of antibodies against viral, bacterial and parasitic agents has been used for differential diagnosis of acute versus recent/past infections. The low-avidity antibodies may however, persist for a longer period in some individuals.
We studied the association of human papillomavirus (HPV) type 16 antibody avidity with seroprevalence to HPV types 6/11/18/31/33/45. Antibody avidity was analysed for 365 HPV16 seropositive pregnant Finnish and Ugandan women using a modified ELISA.Low avidity of HPV16 antibodies was found in 15% of Finnish and 26% of Ugandan women. Ugandan women with low-avidity HPV16 antibodies had an increased risk estimate for HPV6/11 (odds ratio, OR 2.9; 95%CI 1.01-8.4) seropositivity but not to high-risk HPV types 18/31/33/45.
Association of the low avidity HPV16 antibody "phenotype" with possible susceptibility to infections with other HPV types warrants investigation.
针对病毒、细菌和寄生虫病原体的低亲和力抗体已被用于急性感染与近期/既往感染的鉴别诊断。然而,低亲和力抗体在某些个体中可能会持续更长时间。
我们研究了16型人乳头瘤病毒(HPV)抗体亲和力与6/11/18/31/33/45型HPV血清阳性率之间的关联。使用改良的酶联免疫吸附测定法(ELISA)对365名芬兰和乌干达HPV16血清阳性孕妇的抗体亲和力进行了分析。在15%的芬兰妇女和26%的乌干达妇女中发现了低亲和力的HPV16抗体。HPV16抗体亲和力低的乌干达妇女HPV6/11血清阳性的风险估计增加(优势比,OR 2.9;95%置信区间1.01-8.4),但对18/31/33/45型高危HPV则不然。
低亲和力HPV16抗体“表型”与对其他HPV类型感染的易感性之间的关联值得研究。
