2008年河北省健康人群流脑抗体水平分析

[目的]了解河北省健康人群A、C群脑膜炎奈瑟氏菌(Nm)抗体水平,为制定预防控制流行性脑脊髓膜炎(流脑)措施提供依据。[方法]严格按照《全国流行性脑脊髓膜炎防控工作方案》要求分组采样,统一采用ELISA方法测定健康人群血清中A群、C群流脑IgG抗体含量。[结果]全省3市(邯郸、保定、承德市)8个年龄组共检测702人,流脑A群抗体平均含量15.92μg/ml,A群阳性率84.50%(590/702),阳性抗体含量中位数为10.64μg/ml;各年龄组之间抗体阳性率差异有统计学意义(χ2=37.40,P﹤0.01);流脑C群抗体平均含量11.31μg/ml,C群阳性率71.37%(501/702),阳性抗体含量中位数为5.41μg/ml,各年龄组之间抗体阳性率差异有统计学意义(χ2=29.69,P﹤0.05)。3个监测点之间,A群Nm抗体阳性率差异无统计学意义,C群Nm抗体阳性率差异有统计学意义。[结论]我省健康人群A群流脑抗体阳性率维持在较高水平,C群流脑抗体阳性率相对较低,表明大部分人对A群流脑有免疫力,提示今后应加强A+C流脑疫苗的预防接种。
