Performance of the EULAR/ACR 2019 Classification criteria for systemic lupus erythematosus in early disease, across sexes and ethnicities

Background: EULAR/ACR 2019 SLE Classification Criteria were validated in an international cohort. Objectives: To evaluate performance characteristics of SLE classification systems in sex, race/ethnicity, and disease duration subsets. Methods: Sensitivity and specificity of the EULAR/ACR 2019, SLICC 2012 and ACR 1982/1997 criteria were evaluated in the validation cohort. Results: The cohort consisted of female (n=1098), male (n=172), Asian (n=118), Black (n=68), Hispanic (n=124) and White (n=941) patients ; and patients with an SLE duration of 1-3 years (n=196), 3-5 years (n=157), and ≥5 years (n=879). Among patients with 1-3 years disease duration, the EULAR/ACR criteria had better sensitivity than the ACR criteria (97% (95%CI 92-99%) vs 81% (95%CI 72-88%). The new criteria performed well in men (sensitivity 93%, specificity 96%) and women (sensitivity 97%, specificity 94%). The new criteria had better sensitivity than the ACR criteria in White (95% vs 83%), Hispanic (100% vs 86%) and Asian patients (97% vs 77%). Conclusion: The EULAR/ACR 2019 criteria perform well in patients with early disease, and across sexes and ethnicities.
