The 2012 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for polymyalgia rheumatica (PMR) were published in 2012. The present study aimed to assess the 2012 EULAR/ACR classification criteria for PMR in Japanese patients diagnosed with PMR using Bird's criteria.
The study included 75 patients diagnosed using Bird's criteria. The patients were divided into fulfilled and not-fulfilled groups according to whether they met the 2012 EULAR/ACR classification criteria for PMR. The factors in the new criteria were morning stiffness duration > 45 min, hip pain or limited range of motion, absence of rheumatoid factor or anti-citrullinated protein antibody, and absence of other joint involvement.
Thirty-two of the patients diagnosed with PMR using Bird's criteria met the new EULAR/ACR classification criteria, while the remaining 43 patients did not meet the new criteria. Among the factors, only morning stiffness duration > 45 min was an independent predictive factor.
A morning stiffness duration > 45 min is the only independent predictive factor for differentiating patients diagnosed according to the new 2012 EULAR/ACR classification criteria for PMR.
2012年欧洲抗风湿病联盟（EULAR）/美国风湿病学会（ACR）的风湿性多肌痛（PMR）分类标准于2012年发布。本研究旨在使用伯德标准评估2012年EULAR/ACR的PMR分类标准在诊断为PMR的日本患者中的应用情况。
该研究纳入了75例使用伯德标准诊断的患者。根据患者是否符合2012年EULAR/ACR的PMR分类标准，将其分为符合组和不符合组。新标准中的因素包括晨僵持续时间>45分钟、髋部疼痛或活动范围受限、类风湿因子或抗瓜氨酸化蛋白抗体阴性以及无其他关节受累。
75例使用伯德标准诊断为PMR的患者中，32例符合新的EULAR/ACR分类标准，其余43例不符合新标准。在这些因素中，只有晨僵持续时间>45分钟是一个独立的预测因素。
晨僵持续时间>45分钟是根据2012年EULAR/ACR新分类标准区分诊断为PMR患者的唯一独立预测因素。
