Abstract

Objective: Different classification criteria for systemic lupus erythematosus (SLE) have been proposed for many years. The most widely used and accepted criteria has been the 1997 American College of Rheumatology (ACR) criteria. In 2012, the Systemic Lupus International Collaborating Clinics (SLICC) criteria were published in an attempt to improve the clinical relevance of SLE criteria. In 2017, weighted criteria were proposed that included entry criteria, something the 1997 ACR and the 2012 SLICC criteria did not identify. The aim of the present study was to validate the 2017 weighted criteria, the 1997 ACR criteria, and the 2012 SLICC criteria and compare the sensitivities and specificities in pediatric SLE.

Methods: For the past 15 years, retrospective chart review of patients diagnosed with SLE before age 19 years was conducted. The controls were patients referred for serologies positive for antinuclear antibodies but did not fulfill criteria for diagnosis of SLE at the initial visit or were diagnosed with another autoimmune disease. The 3 classification criteria sets were applied to these patients and compared against a gold standard of physician diagnosis.

Results: A total of 156 patients were diagnosed with SLE. The sensitivity for the 2017 weighted criteria was 0.974 (95% confidence interval [95% CI] 0.936-0.993) and the specificity was 0.984 (95% CI 0.966-0.994). The sensitivity for the 1997 ACR criteria was 0.872 (95% CI 0.809-0.920) and the specificity was 1.00 (95% CI 0.990-1.000). The sensitivity for the 2012 SLICC criteria was 0.974 (95% CI 0.936-0.993) and the specificity was 0.997 (95% CI 0.985-1.000).

Conclusion: The 2017 weighted criteria and the 2012 SLICC criteria were more sensitive than the 1997 ACR criteria. There were no significant differences in sensitivity and specificity between the 2012 SLICC and the 2017 weighted criteria.
