吉兰-巴雷综合征(GBS)是一种少见但可危及生命的、自身免疫介导的周围神经病。GBS通常由感染引发,发病率可在感染性疾病暴发期间增加,如2013年法属波利尼西亚和2015年拉丁美洲的寨卡病毒流行期间,该病的发病率明显上升。由于GBS的临床表现和病程多种多样,其诊疗存在一定的复杂性,而目前尚无可用的国际性临床诊疗指南。本文作者撰写了一份适用于全球的GBS诊疗指南,特别是在疾病暴发期间,以期为临床医生提供指导。本指南根据当前文献和专家共识撰写而成,采用10步式结构,以便在临床实践中更好地应用。本文首先介绍了GBS的诊断标准、临床变异和鉴别诊断;其次,通过10个步骤介绍了GBS的早期识别和诊断、收治重症监护室的指征、治疗指征和选择、疾病进展的监测和处理、临床病程和结局的预测,以及并发症和后遗症的处理。
