We applied the 2022 American College of Rheumatology (ACR)/European Alliance of Association for Rheumatology (EULAR) criteria to Korean patients previously diagnosed with giant cell arteritis (GCA) according to the 1990 ACR criteria and validated its clinical efficiency.
Nine patients with GCA were included. The proportion of patients meeting each item of the 1990 ACR criteria and the 2022 ACR/EULAR criteria were assessed.
The median age was 65.0 years, and 77.8% of the patients were women. Seven (77.8%) patients had polymyalgia rheumatica. All nine patients were reclassified as having GCA according to the 2022 ACR/EULAR criteria. Among the 10 items of the 2022 ACR/EULAR criteria, the item contributing the most to the reclassification was elevated acute-phase reactant levels (100%), followed by new temporal headache (77.8%) and fluorodeoxyglucose positron emission tomography activity throughout the aorta (77.5%).
In this study, for the first time, we demonstrated a concordance rate of 100% between the two criteria in Korean patients previously diagnosed with GCA. Moreover, we also clarified the major contributors to the reclassification according to the 2022 ACR/EULAR criteria.
我们将2022年美国风湿病学会（ACR）/欧洲抗风湿病联盟（EULAR）标准应用于先前根据1990年ACR标准诊断为巨细胞动脉炎（GCA）的韩国患者，并验证了其临床有效性。
纳入9例GCA患者。评估符合1990年ACR标准和2022年ACR/EULAR标准各项的患者比例。
中位年龄为65.0岁，77.8%的患者为女性。7例（77.8%）患者患有风湿性多肌痛。根据2022年ACR/EULAR标准，所有9例患者均被重新分类为患有GCA。在2022年ACR/EULAR标准的10项中，对重新分类贡献最大的项目是急性期反应物水平升高（100%），其次是新发颞部头痛（77.8%）和主动脉全程氟脱氧葡萄糖正电子发射断层扫描活性（77.5%）。
在本研究中，我们首次证明了先前诊断为GCA的韩国患者中这两种标准之间的符合率为100%。此外，我们还明确了根据2022年ACR/EULAR标准进行重新分类的主要因素。
