粪类圆线虫

Can Med Assoc J. 1978 Apr 22;118(8):933-5.

Strongyloides stercoralis, a nematode not well known to many Canadian physicians, infects 35% of some tropical populations. Larvae can be isolated from the stools in 25% of cases and from duodenal aspirates in 95%. Treatment is with thiabendazole given twice daily in a dose of 25 mg/kg up to a maximum of 1.5 g/d. Frenquently an individual with a previously asymptomatic infection presents with hyperinfection and death rapidly ensues, but usually classical symptoms are present. Such a case is described. Immunosuppression is frequently associated with the hyperinfective state.

粪类圆线虫是一种许多加拿大医生并不熟知的线虫，在一些热带人群中，其感染率达35%。25%的病例可从粪便中分离出幼虫，95%的病例可从十二指肠抽吸物中分离出幼虫。治疗方法是使用噻苯达唑，每日两次，剂量为25mg/kg，最大剂量为1.5g/天。既往无症状感染的个体常出现重度感染，随后迅速死亡，但通常会出现典型症状。本文描述了这样一个病例。免疫抑制常与重度感染状态相关。
