O42 Patients with systemic lupus erythematosus experience poor health-related quality of life despite a low disease activity state or remission

Objective Patients with systemic lupus erythematosus (SLE) experience poor health-related quality of life (HRQoL), despite attaining responses by the SLE Responder Index (SRI)-4.1 We aimed to determine the prevalence of poor HRQoL in SLE patients who had attained low disease activity (LDA) or remission and sustained LDA or remission after a 52-week therapeutic intervention in a clinical trial setting. Methods A post-hoc analysis was conducted using data from four trials: BLISS-52, BLISS-76, BLISS-SC, and EMBRACE. We defined LDA according to the Lupus LDA State (LLDAS) criteria, i.e., SLEDAI-2K ≤4 excluding major organ activity or fever or new activity since the previous assessment, Physician Global Assessment (PGA) ≤1 (scale 0–3), and prednisone ≤7.5 mg/day. We defined remission according to the Definitions of Remission in SLE (DORIS) criteria i.e., clinical (c)SLEDAI-2K=0, PGA Results Of 480, 239, 363, and 177 patients who attained LLDAS, DORIS remission, sustained LLDAS, and sustained DORIS remission at week 52, respectively, 16%, 14%, 15%, and 9% reported poor SF-36 PCS and 12%, 12%, 13%, and 14% reported poor MCS scores, respectively. The greatest percentages were reported in the physical functioning domain (23–26%), followed by the general health domain (16–26%), while 19–26% reported FACIT-F scores ≤30. Lastly, pain/discomfort was the EQ-5D dimension that yielded the greatest frequencies of poor experience (28–29%) (figure 1). Conclusion Despite attainment of LLDAS or remission, substantial proportions of SLE patients experience poor HRQoL, indicating that current LDA and remission definitions fail to capture important aspects of patients' well-being.
