- Treat-to-target recommendations have identified ‘remission’ as a target in systemic lupus erythematosus (SLE), but recognise that there is no universally accepted definition for this. Therefore, we initiated a process to achieve consensus on potential definitions for remission in SLE.MethodsAn international task force of 60 specialists and patient representatives participated in preparatory exercises, a face-to-face meeting and follow-up electronic voting. The level for agreement was set at 90%.ResultsThe task force agreed on eight key statements regarding remission in SLE and three principles to guide the further development of remission definitions:1. Definitions of remission will be worded as follows: remission in SLE is a durable state characterised by …………………. (reference to symptoms, signs, routine labs).2. For defining remission, a validated index must be used, for example, clinical systemic lupus erythematosus disease activity index (SLEDAI)=0, British Isles lupus assessment group (BILAG) 2004 D/E only, clinical European consensus lupus outcome measure (ECLAM)=0; with routine laboratory assessments included, and supplemented with physician's global assessment.3. Distinction is made between remission off and on therapy: remission off therapy requires the patient to be on no other treatment for SLE than maintenance antimalarials; and remission on therapy allows patients to be on stable maintenance antimalarials, low-dose corticosteroids (prednisone ≤5 mg/day), maintenance immunosuppressives and/or maintenance biologics.The task force also agreed that the most appropriate outcomes (dependent variables) for testing the prognostic value (construct validity) of potential remission definitions are: death, damage, flares and measures of health-related quality of life.ConclusionsThe work of this international task force provides a framework for testing different definitions of remission against long-term outcomes.

- The aim of this study is to identify prognostic factors of persistent disease activity and long quiescence in systemic lupus erythematosus (SLE).MethodsPatients enrolled in the Hopkins Lupus Cohort from 1987 to 2012, who attended at least three visits per year during 3 consecutive years following baseline and had available information on disease activity were included. Patterns of SLE disease activity over the 3-year period were defined as: persistent long quiescent (pLQ), persistent relapsing-remitting (pRR), persistent chronic active (pCA) and mixed based on Modified SLE Disease Activity Index (M-SLEDAI). Possible predictors of pCA (vs pLQ, pRR and mixed) and pLQ (vs pCA, pRR and mixed) were identified by univariate and multivariate logistic regression analyses.Results916 patients were included. In the multivariate analysis, use of hydroxychloroquine (OR: 0.45, 95% CI 0.22 to 0.92, p=0.03), African American ethnicity (OR: 2.36, 95% CI 1.15 to 4.85, p=0.02) and baseline SLEDAI (OR: 1.10, 95% CI 1.03 to 1.17, p=0.005) remained significant predictors of pCA. Higher education (>12 years; OR. 2.07, 95% CI 1.07 to 4.03, p=0.03) and lower baseline SLEDAI (OR: 0.67, 95% CI 0.56 to 0.82, p<0.001) were significant predictors of pLQ, while African American (OR: 0.38, 95% CI 0.17 to 0.83, p=0.02) and female patients (OR: 0.26, 95% CI 0.12 to 0.57, p<0.001) were less likely to achieve pLQ.ConclusionAfrican American ethnicity and high disease activity at baseline predict chronic activity in SLE, regardless of treatment, years of education and income. Higher education, low disease activity at baseline and male sex predict long quiescence. The use of hydroxychloroquine is independently associated with a lower risk of chronically active disease.
