Sažetak
Background/Purpose: The EULAR/ACR 2019 Classification Criteria for SLE have been validated in an international cohort of 696 SLE patients and 574 non-SLE patients with a sensitivity of 96.1% and a specificity of 93.4%. We comparatively evaluated the performance characteristics of the SLE classification systems in subsets of the validation cohort with regard to gender, race/ethnicity, and disease duration. Methods: 21 SLE expert centers from 16 countries submitted up to 100 SLE cases and 100 SLE mimicking controls each, using a standardized form without knowledge of the new criteria system to form the validation cohort. Cases and control diagnosis (SLE or not SLE) were independently verified by 3 SLE experts. The EULAR/ACR 2019 classification criteria validation cohort consisted of female (n=1, 098) and male (n=172) patients ; Asian (n=118), Black (n=68), Hispanic (n=124) and White (n=941) patients ; and patients with an SLE duration of less than 1 year (n=34), 1-3 years (n=196), 3-5 years (n=157), and 5 or more years (n=879). Sensitivity and specificity with 95% confidence intervals (CI) were estimated for the EULAR-ACR 2019 criteria, the SLICC 2012 criteria and the ACR 1997 criteria. Results: As shown in Table 1, most of the point estimates for sensitivity and specificity in subsets lay within the 95% confidence intervals of the sensitivity and specificity of the EULAR/ACR 2019 criteria validation. In particular, sensitivity and specificity for all race/ethnicity groups were within the confidence intervals or even higher. Formally, the sensitivity was slightly lower for male patients, corresponding to a higher specificity, but the male 95% confidence intervals (0.86-0.98 for sensitivity, 0.90-0.99 for specificity) overlapped with those of the full cohort. Sensitivity appeared independent of disease duration at least from year 1 on, with all 95% confidence intervals overlapping (for the first year after diagnosis 0.52-1.00 for sensitivity, 0.69-0.97 for specificity). Conclusion: The point estimates of sensitivity and specificity suggest that the EULAR/ACR 2019 SLE classification criteria perform well in diverse race/ethnicity groups, in men and in early disease. These results now need to be independently validated in larger groups of African American/Black, Asian, and Hispanic patients, male patients and in early disease.
