摘要
目的:重症肌无力(MG)做为一种自身免疫性疾病,免疫治疗可使大多数患者病情缓解,但症状容易反复,尤其全身型患者甚至发生肌无力危象,淋巴细胞亚群失调被认为是参与MG发病的主要因素之一,本研究旨在探讨外周血NK淋巴细胞及调节性B淋巴细胞(Breg)亚群与MG患者症状波动之间的关系。材料与方法:选取54名确诊重症肌无力的患者,将其分为三组:眼肌型组、全身型症状加重组和全身型症状缓解组,同时选取10名健康志愿者做为对照组。采用流式细胞术分别测定其外周血中NK及Breg淋巴细胞亚群百分比。结果:Breg淋巴细胞亚群百分比在全身型两组中均明显降低,与对照组比较具有统计学意义(加重组:6.93±1.18%;缓解组:6.56±1.32%;对照组:15.97±2.88%;P=0.,P=0.);而NK淋巴细胞亚群百分比在全身型症状缓解组则明显升高,与症状加重组及对照组比较具有统计学意义(加重组:12.32±1.42%;缓解组20.69±3.45%,对照组:11.33±0.95%;P=0.;P=0.)。结论:Breg淋巴细胞亚群失调参与全身型重症肌无力的发病,而NK淋巴细胞亚群的变化则与全身型重症肌无力的症状波动密切相关,有可能成为监测重症肌无力病情变化及免疫治疗效果的有效指标。
