背景:
了解重症肌无力(MG)的治疗模式对临床实践至关重要,但目前纵向数据有限。
目的:
本研究旨在概述疾病病程中不同亚组的治疗模式。
方法:
所有纳入荷兰-比利时重症肌无力登记系统的成年患者,包括乙酰胆碱受体(AChR)、肌肉特异性激酶(MuSK)阳性及血清阴性重症肌无力(MG)患者。AChR-MG 患者被分为早发型(EOMG,≤50 岁)和晚发型(LOMG,>50 岁)MG。采用混合效应回归模型比较不同亚组间的差异。
结果:
共纳入506例患者(147例AChR EOMG,265例AChR LOMG,26例MuSK,94例血清阴性MG)。其中84例患者在确诊后一年内有可用数据。大多数患者初始治疗使用溴吡斯的明(93%;78/84),其次为皮质类固醇(52%;44/84)和硫唑嘌呤或吗替麦考酚酯(30%;25/84)。十年后,溴吡斯的明(65%;54/83)和皮质类固醇的使用率下降(36%;30/83),而硫唑嘌呤和吗替麦考酚酯的使用率上升至55%(46/83)。与AChR MG患者相比,血清阴性MG患者接受的治疗较少,且该差异独立于功能状态和病程(OR 0.38,95% CI 0.17–0.84,p = 0.018),且较少使用皮质类固醇(OR 0.15,95% CI [0.05–0.41],p < 0.001)。LOMG患者较EOMG患者更常使用免疫抑制剂(OR 4.69,95% CI 1.16–19.02,p = 0.031)。
结论:
该分析为不同重症肌无力患者亚组的治疗模式提供了有价值的见解。有相当比例的患者仍在依赖皮质类固醇,表明对替代治疗方案的需求持续存在。
