2017年北京市健康成年人血清中季节性流感抗体水平分析

Analysis on antibody levels to seasonal influenza viruses in healthy adults in Beijing, 2017

    摘要
  • 摘要:
    目的通过对北京市健康成年人季节性流行性感冒（流感）免疫水平的检测，为流感流行趋势进行预测预警和制定有效防控措施提供参考依据。
    方法2017年4月对北京市6个区（县）随机选取调查对象进行问卷调查，并采集血清标本进行甲型H1N1流感（H1N1）、甲型H3N2亚型（H3N2）、乙型Victoria系（BV）、乙型Yamagata系（BY）流感病毒抗体检测，比较不同组间的抗体阳性率及几何平均滴度（GMT）水平。
    结果共调查1 163人，其中645人携带≥1种抗体阳性，总体阳性率为55.46%；H1N1、H3N2、BV、BY阳性率分别为25.62%、44.88%、1.98%和3.53%；H3N2抗体的GMT最高（1∶24.75），BV抗体GMT最低（1∶5.67），各亚型抗体阳性率及GMT差异有统计学意义（P＜0.001）。 成年男性H3N2、BV、BY抗体阳性率及H3N2抗体GMT高于女性，差异有统计学意义（P＜0.05）；不同地区来源人群H1N1、H3N2抗体阳性率及GMT差异有统计学意义（P＜0.05）；各年龄组间H1N1、H3N2、BY抗体阳性率及GMT差异有统计学意义（均P＜0.001），其中≥60岁老年组H3N2、抗体阳性率及GMT最高，18 ~ 29岁青年组H1N1、BY抗体阳性率及GMT最高；过去1年内有接种史组H1N1、H3N2、BY抗体阳性率及GMT均高于无接种史组，差异有统计学意义（P＜0.05）。
    结论北京市健康成年人中BV、BY抗体阳性率较低，导致流感暴发的风险较大；影响不同亚型流感病毒抗体水平的影响因素略有不同，疫苗接种等因素与抗体阳性存在相关性。

     

    Abstract:
    ObjectiveTo investigate the immune level against seasonal influenza viruses in healthy adults in Beijing.
    MethodsIn April 2017, the study subjects were randomly selected from communities in six districts in Beijing. A questionnaire survey was conducted among them and serum samples were collected from them to detect the antibodies against seasonal influenza viruses, including influenza A (H1N1) pdm09 virus, influenza A (H3N2) virus, influenza B virus Victoria lineage and influenza B virus Yamagata lineage. The positive rates of the antibodies and the genmetric mean titers (GMTs) in different groups were compared.
    ResultsA total of 1 163 healthy adults were surveyed, in which 645 were positive for at least one antibody. The positive rates for A (H1N1) pdm09, A (H3N2), B Victoria lineage and B Yamagata lineage viruses were 25.62%, 44.88%, 1.98% and 3.53% respectively. The antibody against A (H3N2) virus had the highest GMT of 1∶24.75, while the GMT of antibody against B Victoria lineage virus was lowest (1∶5.67). The differences in antibody positive rate and GMT were significant among the four subtype influenza viruses (P＜0.001). The positive rates of antibodies against A (H3N2), B Victoria lineage and B Yamagata lineage viruses and the GMT of A (H3N2) virus antibody were higher in males than in females (P＜0.05). There were significant differences in positive rates of antibodies against A (H1N1) pdm09 virus and A (H3N2) virus and the GMTs among the populations from different districts (P＜0.05). Similar results were observed in different age groups for the positive rates of antibodies against A (H1N1) pdm09, A (H3N2) and B Yamagata lineage viruses (P＜0.001). The antibody level to A (H3N2) virus and GMT were highest in age group ≥60 years , while the antibody levels to A (H1N1) pdm09 virus and B Yamagata lineage virus and GMTs were highest in age group 18–29 years. The persons receiving vaccination in past year had higher positive rates of antibodies and GMTs against A (H1N1) pdm09, A (H3N2) and B Yamagata lineage viruses compared with unvaccinated persons (P＜0.05).
    ConclusionThe positive rates of antibodies against B Victoria lineage and B Yamagata lineage viruses were low in healthy adults in Beijing, suggesting the high risks for outbreaks of infections of B Victoria lineage and B Yamagata lineage viruses. The factors influencing the antibody levels of different subtype influenza viruses slightly differed, and there was a correlation between vaccination or other factors and antibody positive rate.
