A neutralization enzyme immunoassay (N-EIA) was used to determine the neutralizing serum antibody titers to influenza A/Taiwan/1/86 (H1N1) and Beijing/353/89 (H3N2) viruses after vaccination of 51 human immunodeficiency virus (HIV) type 1-infected individuals and 10 healthy noninfected controls against influenza virus infection. Overall, the N-EIA titers correlated well with the hemagglutination-inhibition (HAI) titers that were observed in the same samples in a previous study (F. P. Kroon, J. T. van Dissel, J. C. de Jong, and R. van Furth, AIDS 8:469-476,1994). The N-EIA appeared to be more sensitive than the HAI test. Significantly more fourfold or higher rises in N-EIA titer and higher mean N-EIA titers occurred in HIV-infected individuals with > or =200 CD4+ cells per microl than in those with <200 CD4+ cells per microl.
采用中和酶免疫测定法(N-EIA),检测了51例1型人类免疫缺陷病毒(HIV)感染者和10名健康未感染者接种流感病毒疫苗后,针对甲型流感病毒/台湾/1/86(H1N1)和北京/353/89(H3N2)的血清中和抗体滴度。总体而言,N-EIA滴度与先前研究中在相同样本中观察到的血凝抑制(HAI)滴度密切相关(F.P. Kroon、J.T. van Dissel、J.C. de Jong和R. van Furth,《艾滋病》8:469-476,1994)。N-EIA似乎比HAI试验更敏感。每微升CD4+细胞≥200的HIV感染者中,N-EIA滴度有四倍或更高升高以及平均N-EIA滴度更高的情况,显著多于每微升CD4+细胞<200的感染者。
