摘要: 目的 了解122例脑炎脑膜炎症候群患者血清中猪囊尾蚴(Cysticercus cellulosae)、刚地弓形虫(Toxoplasma gondii)IgG、IgM抗体阳性情况,为临床诊断脑炎脑膜炎症候群患者的病原提供参考依据。 方法 2014年8月至2015年12月,采集上海交通大学附属第六人民医院、江苏省丹阳市人民医院和江苏大学附属医院收治的脑炎脑膜炎症候群患者血清,用猪囊尾蚴和刚地弓形虫IgG、IgM抗体检测试剂盒检测血清中抗猪囊尾蚴、刚地弓形虫的抗体,计算抗体阳性率,分析其性别分布、急性感染季节分布、年龄分布和职业分布情况。 结果 122例脑炎脑膜炎症候群患者血清中,猪囊尾蚴IgG和IgM抗体阳性分别为17例、22例,阳性率为13.9%(17/122)和18.0%(22/122);刚地弓形虫IgG和IgM抗体阳性分别为29例和8例,阳性率为23.8%(29/122)和6.6%(8/122)。男性猪囊尾蚴和刚地弓形虫阳性率为30.6%(22/72)和31.9%(23/72),女性为26.0%(13/50)和24.0%(12/50)。猪囊尾蚴IgM抗体阳性率季节分布分别为12.0%(3/25)、27.0%(17/63)、6.9%(2/29)和0/5;阳性率最高的年龄段出现在13~25岁组,为45.0%(9/20);工人组阳性率最高,为7/14。刚地弓形虫IgM抗体阳性率季节分布为4.0%(1/25)、11.1%(7/63)、0(0/29)和0/5;阳性率最高出现在>65岁组,为44.0%(11/25);不同职业中其他组的阳性率最高,为4/10。猪囊尾蚴、刚地弓形虫抗体阳性率在性别、季节、年龄和职业分布上差异均无统计学意义(P>0.05)。 结论 122例脑炎脑膜炎症候群患者血清猪囊尾蚴、刚地弓形虫抗体阳性率较高,临床诊断该症候群病原时应结合其寄生虫血清学检测结果,考虑感染寄生虫的可能性。

Abstract: Objective To examine the IgG and IgM antibodies for parasites Cysticercus cellulosae and Toxoplasma gondii in 122 patients with meningitis encephalitis syndrome, and provide basis for clinical diagnosis of the meningitis encephalitis syndrome. Methods The sera were collected from patients with meningitis encephalitis syndrome in Shanghai Jiaotong University Affiliated Sixth People’s Hospital, People’s Hospital of Danyang City, and Jiangsu University Affiliated Hospital from August, 2014 to December, 2015. Serum IgG and IgM antibodies for cysticercus and T. gondii were examined using antibody test kits. The antibody positive rate was calculated and its distribution was analyzed by gender, season, age and occupation. Results A total of 122 patients with meningitis encephalitis syndrome were included. Seventeen and 22 patients of them were positive for IgG (13.9%, 17/122) and IgM(18.0%, 22/122) against cysticercus, respectively, while 29 and 8 cases were positive for IgG (23.8%, 29/122) and IgM (6.6%, 8/122) against T. gondii. The positive rate of cysticercus and T. gondii in males was 30.6%(22/72) and 31.9%(23/72) respectively, while that in females was 26.0%(13/50) and 24.0% (12/50). The positive rate of IgM against cysticercus was 12.0%(3/25), 27.0%(17/63), 6.9% (2/29), and 0(0/5) from spring to winter, highest within 13-25 years(45.0%, 9/20) among age groups, and highest in workers(7/14) among various occupations. The positive rate of IgM against T. gondii was 4.0%(1/25), 11.1% (7/63), 0(0/29), and 0(0/5) from spring to winter, highest in ages >65 years(44.0%, 11/25), and highest in patients with other occupations(4/10). There was no statistically significant difference in the positive rate between males and females, and among different seasons, ages and occupations. Conclusion The positive rate of antibodies against cysticercus and T. gondii is high in the patients included, suggesting that a serological test for parasite infection might be performed during clinical diagnosis of meningitis encephalitis syndrome.
