Session Title: SLE – Clinical Poster I: Epidemiology & Pathogenesis
Session Type: Poster Session (Sunday)
Session Time: 9:00AM-11:00AM
Background/Purpose: Disease activity in systemic lupus erythematosus (SLE) is understood differently by patients and physicians; furthermore, there are no reliable measures for patients to assess their levels of disease activity. The LFA-REAL PRO has been proposed for addressing this void, and it is expected to correlate with HRQoL and with other PROs. The aim of this study was to determine the correlations between LFA-REAL PRO and HRQoL, fatigue and work disability.
Methods: A cross-sectional analyses of patients from a single-center cohort was performed. The disease activity measure included was the LFA-REAL PRO (0-1200); PROs included were LupusQoL (with its eight domains), SF-36 (with its eight domains and two main subcomponents), FACIT (as a measure of fatigue) and WPAI (as a measure of work productivity impairment). For the LFA-REAL PRO and WPAI, the higher the scores, the worse the disease activity and the more impaired the patient is; for the SF-36, LupusQoL and FACIT is the opposite. The correlation between these indices was evaluated with Pearson correlations.
Results: One-hundred and sixty-nine patients with SLE, with a mean age of 45.8 (SD: 14.2), 156 (92.3%) were female. The mean (SD) the LFA-REAL PRO was 239.6 (187.7), the Physical Component Summary SF-36 was 53.7 (22.1) and the Mental Component Summary SF-36 was 54.6 (21.0). The mean value of the components of the LupusQoL ranged between 41.0 and 69.4. The FACIT was 33.2 (10.5), the percentage of overall work productivity impairment was 30.8 (28.1) and of activity impairment was 36.1 (29.9). LFA-REAL PRO correlated with all domains of LupusQoL, SF-36, FACIT and WPAI, with the exception of absenteeism.
Conclusion: The LFA-REAL PRO correlates with several measures of HRQoL and other outcomes relevant to lupus patients like fatigue and work disability, suggesting that this index could be useful in monitoring them.
