NEJM:粪类圆线虫重度感染-案例报道

2017-06-15 xing.T MedSci原创

虽然肠道线虫S.线虫可以保持沉默,但免疫抑制可导致感染综合征,其特点是在蠕虫负担大幅增加,伴有器官浸润。侵入肠壁可促进细菌移位,对于那些来自或前往一个寄生虫流行的地方的个体,在免疫抑制治疗之前应考虑检测和经验治疗S.线虫,以减少感染综合征的风险。

患者为一名47岁男性,曾经生活在老挝,服用强的松治疗皮肌炎,该患者有腹痛、黑便、发热、咯血4天以及出现皮疹2周。就诊前一个月,该患者入院并接受大剂量糖皮质激素治疗弥漫性肺泡出血。出血原因尚不明确,但采用糖皮质激素治疗患者病情得到改善。

这次就诊时,患者出现低血压和心动过速;体检发现在腹部有网状紫癜性斑块,伴有较为灰暗的中心,延伸到侧面、腹股沟、阴茎、大腿(如图A所示)。进展性呼吸窘迫,该患者接受气管插管。支气管镜检查显示弥漫性肺泡出血,发现粪类圆线虫的幼虫。皮疹活检发现丝状幼虫(如图B箭头所示)和寄生虫分布在真皮胶原纤维束之间。血培养得到粪肠球菌和肺炎克雷伯菌。

除了进行针对多种微生物引起的菌血症抗生素治疗外,该患者采用伊维菌素和阿苯达唑治疗,最后,该患者完全康复。
