NEJM:耐药粟粒型肺结核-病例报道

2018-02-15 xing.T MedSci原创

由于确认耐药性的试验结果可能需要数周才能恢复,因此,该疗法实际上已转变为标准的抗药性结核病治疗。在治疗开始后2周内病人体温恢复正常,2个月时重复CT显示有改善。耐药试验结果恢复后,异烟肼耐药结核得到确诊。

患者为一名既往健康的8岁女孩,因干咳和持续发烧3个月而被送到医院就诊。

胸片(如图A所示)和随后的增强CT扫描(如图B所示)表现为弥漫性、粟粒性(即小米样)图案的大小均匀,弥漫整个肺部的小结节。软组织窗(未显示)显示纵隔淋巴结坏死。结核菌素皮试和干扰素-γ释放试验阳性,痰抗酸杆菌涂片阴性。培养液为多种体液,包括痰液、支气管肺泡灌洗和脑脊液。



在等待培养结果的过程中,已经开始经验性的抗结核一线治疗,然而,经过2个月的治疗,病人的病情没有好转。因为体液培养仍为阴性,在胸腔镜下进行肺活检;苏木精和伊红染色的活检标本呈干酪样坏死,细菌和抗酸染色阳性(如图C箭头所示)。怀疑为耐药结核病。

由于确认耐药性的试验结果可能需要数周才能恢复,因此,该疗法实际上已转变为标准的抗药性结核病治疗。在治疗开始后2周内病人体温恢复正常,2个月时重复CT显示有改善。耐药试验结果恢复后,异烟肼耐药结核得到确诊。
