Remission in SLE-do DORIS criteria match the treating physician's judgment? A cross-sectional study to assess reasons for discordance.

Objectives: The definition of an accurate target for a treat-to-target approach in SLE has been challenging over past years, and recently the DORIS definitions of remission were presented by the international DORIS task force. It was our aim to assess the frequency of DORIS remission and LLDAS in our SLE cohort and their agreement with the treating physician's (DORIS-) independent remission judgement. Patient characteristics leading to lack of agreement and incoherence ought to be identified.

Methods: In this monocentric cross-sectional study, patients with SLE were enrolled and assessed between September 2016 and December 2017. DORIS remission definitions were applied and after the clinical consultation, the treating physicians gave his/her opinion on whether the patient was in remission. Regression analyses were performed to identify parameters influencing physician remission.

Results: A total of 233 patients were included (87.6% female); 99 (42.5%) patients fulfilled any of the four DORIS remission definitions, while 126 patients were in remission according to their physician's judgement. We observed discordance in the assessment of remission in 53 patients (22.7%). Physician remission was influenced by disease activity [odds ratio (OR) 0.76, 95% CI: 0.63, 0.90], disease and/or treatment-related damage (OR 0.78, 95% CI: 0.62, 0.98) and the presence of ds-DNA antibodies (OR 2.47, 95% CI: 1.06, 6.04).

Conclusions: DORIS remission proved an achievable target in our outpatient clinic. Still we found discordance regarding DORIS remission and the treating physician's judgement with a greater number of patients considered in remission by their physicians.
