Abstract

Objective: The objective of this report is to determine the impact of remission and low disease activity state (LDAS) on damage accrual and mortality in systemic lupus erythematosus (SLE) patients. Patients and methods: Visits from the Lupus in Minority populations: Nature vs. Nurture (LUMINA) cohort were categorized into remission (Systemic Lupus Activity Measure (SLAM) score = 0 and prednisone ≤ 5 mg/day and no immunosuppressants), LDAS ((not on remission), SLAM score ≤ 3, prednisone ≤ 7.5 mg/day, no immunosuppressants), or neither: active. Remission and LDAS visits were combined because of the relatively small number of remission visits. Their impact on damage accrual and mortality were examined by Poisson and logistic multivariable regressions adjusting for variables known to affect these outcomes. Results: A total of 3879 visits for 558 patients (28% Caucasian, 37% African descent, 35% Hispanic) were studied. These visits corresponded to 71 in remission, 585 in LDAS, and 3223 active. The longer the percentage of time the patients were in remission/LDAS, the less damage accrual observed (rate ratio 0.1773 (95% confidence interval (CI) 0.1216 to 0.2584) p < 0.0001). A trend was observed in terms of mortality although statistical significance was not reached (odds ratio 0.303 (95% CI 0.063 to 1.456), p = 0.1360). Conclusions: The longer the patient's state on Remission/LDAS, the less damage accrual that occurs. The protective effect on mortality was not statistically significant.
