Arthritis Rheumatol:青少年皮肌炎中骨骼肌的功能和结构适应

2019-11-25 xiangting MedSci原创

与对照组相比,长期JDM膝关节伸肌的肌力/耐力较低,活动性疾病低于非活动性疾病。

这项研究旨在比较长期青少年皮肌炎(JDM)患者vs对照组、以及活动性vs非活动性疾病患者的膝关节伸肌肌力/耐力。在患者中探索肌力/耐力与i临床指标ii)身体活动和iii)骨骼肌体液/结构适应之间的关联。

这是一项横断面研究(患者n=44名和44名年龄/性别匹配的对照),研究人员测试了膝关节伸肌的等长肌力(峰值扭矩)和动态肌耐力(总功)、身体活动(加速度计)和肌肉因子(ELISA)。使用经过验证的工具(临床肌肉测试、疾病活动性/损伤和非活动性疾病)以及包括横截面积(CSA)在内的大腿磁共振成像对患者进行检查。采用组织化学法评估股外肌针活检(n=12,年龄≥18y)。

平均病程21.8±11.8y后,患者的峰值扭矩比对照低29 Nm95CI 13-46)(p=0.001),患者的总工作量为738 JIQR 565-1155),对照为1249 JIQR 815-1665)(p<0.001)。活动性和非活动性疾病的峰值扭矩和总工作量均较低(p<0.019);控制四头肌CSA后,只有工作量较低。活动性疾病患者的扭矩和工作量与临床肌肉测试相关(r= 0.57-0.84)。肌肉活检结果表明,活动性和非活动性疾病的纤维类型组成不同,但毛细血管密度相似。

与对照组相比,长期JDM膝关节伸肌的肌力/耐力较低,活动性疾病低于非活动性疾病。研究结果表明在这种临床情况下需要进行更敏感的肌肉测试。研究假设活动性疾病的肌力受损受到与肌肉大小无关的肌肉组织结构/功能适应性的影响。
