AB1289 TESTING DIFFERENT ITEMS INCLUDED IN THE DEFINITION OF REMISSION IN A MULTICENTRE SLE COHORT

Background: Remission is the most desirable target in the treatment systemic lupus erythematosus (SLE) however, a universally accepted definition of remission in SLE is still missing. Objectives: To test the contribution of the different items included into the currently used definitions of remission in SLE. Methods: We studied 646 Caucasian patients from a multicentre lupus cohort followed for at least 5-years: female 585 (90.6%), mean age at baseline 40.59±12.14 years, mean disease duration 9.18±6.86 years. Disease activity was assessed by clinical SLE Disease Activity Index 2000 (cSLEDAI) and SELENA-SLEDAI physician global assessment (PGA), and damage by Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI). To test the performance of the different items included in the definitions of SLE remission [1, 2] we identify 7 subtypes of remission: (1) PGA (0-3) Results: The number of patients achieving remission according to the different definitions is show in Figure 1. The proportion of patients who maintained prolonged remission (5-consecutive years) was: PGA When PGA Conclusion: The prevalence and extent of damage significantly decreased as the time spent in remission increased, irrespective of the remission subtype.
