目的了解四川省雅江县呷拉乡藏族人群绦虫病/囊尾蚴病流行现状。方法通过问卷、体检了解近一年内人群排绦虫史、癫痫发作史、皮下结节以及相关的其他临床表现。对自愿接受治疗的患者用吡喹酮驱除绦虫,用multiplex PCR对虫种进行鉴定。对1例高度怀疑为猪带绦虫患者的粪便标本采用粪-PCR进行检测。用囊液抗原检测血清囊尾蚴病特异性抗体,了解人群囊尾蚴感染水平。结果11.96%(216/1806)的村民近一年内有排绦虫史,1.05%(19/1806)发现皮下结节,0.61%(11/1806)有癫痫发作史。24份虫体标本PCR鉴定结果均为牛带绦虫,1份粪便标本粪-PCR结果为猪带绦虫。4.35%(4/92)人群血清囊尾蚴病抗体阳性。结论牛带绦虫和猪带绦虫共同流行于雅江县呷拉乡,以牛带绦虫为优势虫种。人群囊尾蚴感染率为4.35%。
Objective To understand the prevalence of taeniasis / cysticercosis among Tibetan people in Dala Township, Yajiang County, Sichuan Province. Methods Through the questionnaire, physical examination to understand the history of the crowd of Taian Taichong in the past year, the history of seizures, subcutaneous nodules and other related clinical manifestations. Praziquantel was used to eradicate tapeworms in patients who volunteered to be treated, and multiplex PCR was used to identify the species. A stool specimen from a highly suspected case of Taenia solium was detected by fecal-PCR. Cystic fluid antigen detection of serum cysticercosis-specific antibodies to understand the level of cysticercosis in the crowd. Results 11.96% (216/1806) of the villagers had a history of tapeworm in one year, subcutaneous nodules in 1.05% (19/1806) and seizures in 0.61% (11/1806). The results of PCR identification of 24 specimens were all Taenia saginata, and 1 specimen of feces was stool - PCR result was Taenia solium. 4.35% (4/92) of human serum cysticercosis antibody positive. Conclusion Taenia saginata and Taenia solium were common in Yuala Township, Yajiang County, with Taenia saginata as the dominant species. Cysticercus infection rate of 4.35%.
