Does expert opinion match the definition of Lupus Low Disease Activity State? prospective analysis of 500 patients from a Spanish multicentre cohort

Descripció

• Resum

  Objectives: To apply Lupus Low Disease Activity State (LLDAS) definition within a large cohort of patients and to assess the agreement between the LLDAS and the physician's subjective evaluation of lupus activity. Methods: A cross-sectional analysis of a prospective multicentre study of Systemic Lupus Erythematosus (SLE) patients. We applied the LLDAS and assessed whether there was agreement with the clinical status according to the physiciańs opinion. Results: 508 patients (92% women; mean age (±SD): 50.4 years (± 13.7)). A total of 304 (62.7%) patients were in LLDAS. According to physician assessment, 430 patients (86,1%) were classified as remission or low activity. Overall agreement between both evaluations was 71.4% (95% CI: 70.1-70.5%) with a Coheńs kappa of 0.3 (0.22-0.37). Most cases (96.1%) in LLDAS were classified as remission or low activity by the expert. Of the patients that did not fulfill LLDAS, 126 (70.4%) were classified as having remission/low disease activity. The main reasons for these discrepancies were the presence of new manifestations compared with the previous visit and a SLEDAI 2-K > 4, mainly based on serological activity. Conclusions: Almost two thirds of SLE patients were in LLDAS. There was a fair correlation between LLDAS and the physician's evaluation. This agreement improves for patients fulfilling the LLDAS criteria. The discordance between both at defining lupus low activity, the demonstrated association of LLDAS with better outcomes and the fact that LLDAS is more stringent than physician's opinion imply that we should use the LLDAS as a treat to target goal.
