TLDR The new SLICC criteria for diagnosing lupus are more sensitive and accurate than the old criteria.
The Systemic Lupus International Collaborating Clinics (SLICC) developed and validated new classification criteria for systemic lupus erythematosus (SLE) to improve diagnostic accuracy. The study involved 702 patients for derivation and 690 for validation, showing the SLICC criteria had higher sensitivity (97% vs. 83%) but lower specificity (84% vs. 96%) compared to the American College of Rheumatology (ACR) criteria. The SLICC criteria required at least one clinical and one immunologic criterion or lupus nephritis with specific antibodies, resulting in fewer misclassifications and better alignment with current SLE knowledge.
