目的:探讨2017年EULAR/ACR提出的特发性炎性肌病的分类标准（EULAR/ACR标准）对中国DM患者的适用性，并对EULAR/ACR标准与Bohan & Peter分类标准（B/P标准）进行比较。方法:收集2012年8月至2019年3月郑州大学第一附属医院出院诊断为“DM”患者资料，回顾性分析患者的临床表现和实验室检查，并按照B/P标准及EULAR/ACR标准重新进行分类诊断。结果:共收集453例DM患者女性333例，男性120例，包括临床典型皮肌炎（CDM）330例和无肌病性皮肌炎（CADM）123例。B/P标准和EULAR/ACR标准诊断敏感度分别为68.7%，90.7%，2个标准的诊断一致性低（n κ=0.137，n P<0.01）。92.7%CDM和85.3%CADM患者经EULAR/ACR标准诊断可能性≥55%，86.9%CDM患者和19.5%的CADM患者可被B/P标准诊断。n 结论:EULAR/ACR标准较B/P标准对中国DM患者的诊断敏感度更高，更有利于对ADM分型。“,”Objective:To assess the applicability of European League Against Rheumatism/American College of Rheumatology classification criteria (EULAR/ACR criteria) for dermatomyositis (DM) in Chinese cohort, and compare the differences of the two criteria.Methods:This retrospective study evaluated the clinical data of patients with DM diagnosed by physicians of the first affiliated hospital of Zhengzhou University from August 2012 to March 2019. The Bohan & Peter criteria and EULAR/ACR criteria were used to determine the probability of classification for these patients.Results:453 patients with DM (333 men and 120 women)including 330 classic dermatomyositis (CDM) and 123 clinically amyopathic dermatomyositis(CADM) were included. The sensitivity of Bohan & Peter criteria and EULAR/ACR criteria was 68.7%, 90.7%, respectively, the agreement between the two criteria was poor ( n κ=0.137, n P<0.01). 92.7% of patients with CDM and 85.3% of patients with CADM could meet the suggested 55% minimum probability cutoff to be classified based on EULAR/ACR criteria. 86.9% of patients with CDM and 19.5% of patients with CADM could be diagnosed by Bohan & Peter criteria.n Conclusion:Compared with Bohan & Peter criteria, EULAR/ACR classification has higher sensitivity in Chinese patients with DM, and is more applicable to classify Chinese patients with ADM.
