What is it about?
The classification criteria for Systemic lupus erythematosus (SLE) are fundamental for selecting patients for clinical trials and observational sudies and are often used to assist diagnosis. The SLE diagnosis remains largely clinical and dependent on the expertise/opinion of clinicians, since there are no established tests or diagnostic criteria. The sensitivity of the 'classical' ACR classification criteria for SLE is not optimal. Recently, the new SLICC criteria set was validated and its main advantage is a potentially higher sensitivity to identify lupus patients. We compared in this study the sensitivity of the ACR and SLICC criteria to identify SLE cases in a large multicenter, international cohort of patients from real-life clinical practice.

Why is it important?
We showed that the SLICC criteria allows to identify as SLE cases a larger proportion of patients with a established clinical diagnosis of SLE. Importantly, the improved sensitivity was larger for those patients with a shorter disease duration. Furthermore, the large majority of patients classified as SLE with the ACR criteria were also positively identified by the SLICC criteria.
