不同类型绦虫感染的临床表现特征比较分析

目的 总结并分析带绦虫与裂头绦虫感染的临床表现及实验室指标变化特征。方法 对在北京友谊医院2016年1月—2022年7月就诊的28例肠道绦虫病患者资料进行总结，其中带绦虫病组12例，裂头绦虫病组16例，并分析比较2组患者的临床特点及实验室指标差异。结果 2组患者平均年龄分别为（29.33±15.42）岁和（28.88±11.57）岁。裂头绦虫病组的无症状者比例（10/16）大于带绦虫病组（4/12）,2组中均有4例患者表现为腹痛、腹胀症状。带绦虫病组中，2例患者表现为肛周瘙痒，1例患者表现为体质量下降，但裂头绦虫病组中，患者均无上述2种症状。带绦虫病组中2例（2/12）患者粪便中检测到带绦虫卵，而裂头绦虫病组则有7例（7/16）患者检测到虫卵。28例患者的粪便中均检测到节片。带绦虫病组的北京本地病例为7例（7/12），裂头绦虫病组为10例（10/16）。除2例患者外，其他患者均有食用生或半生可疑牛肉或鱼肉的流行病学史。结论 2种绦虫感染的患者临床症状均轻微，多无症状，但仍有发生严重并发症及2种不同种类寄生虫共感染的风险，流行病学史的询问可提高该疾病的诊断率。

Comparison of clinical characteristics of taeniosis and diphyllobothriosis

Objective?To identify and analyze clinical characteristics and laboratory parameters of patients between taeniosis and diphyllobothriosis. Methods?Retrospective analysis of clinical data and laboratory results was performed on 28 cases of human intestinal cestode infection admitted in Beijing Friendship Hospital, Capital Medical University from January 2016 to July 2022. Of these cases, 12 were diagnosed with taeniosis and 16 were diphyllobothriosis. The difference of clinical characteristics and laboratory indexes were analyzed and compared between the two groups. Results?The median age of patients in the taeniasis and diphyllobothriosis groups was (29.33±15.42) and (28.88±11.57) years, respectively. The number of asymptomatic patients in the diphyllobothriosis group (10/16) was higher than that in the taeniasis group (4/12), Abdominal pain and distention were observed in both groups, but anal pruritus and weight loss were only present in the taeniasis group. Parasitic eggs were found in the feces of 2 patients (2/12) in the taeniasis group and 7 patients (7/16) in the diphyllobothriosis group. All patients were detected expelled proglottids in feces. Seven cases (7/12) and 10 cases (10/16) came from Beijing in 2 groups, respectively. Two patients had no history of consuming raw beef or fish, while the rest had a consumption history. Conclusions?Taeniasis and diphyllobothriosis are typically asymptomatic, but serious complications and co-infection with other parasites have been reported. Notably, epidemiological data is essential to achieve a correct diagnosis.
