Abstract

Objective To evaluate the predictive value of the LFA-REAL ClinRO (Lupus Foundation of America Rapid Evaluation of Activity in Lupus clinician-reported outcome) on damage accrual in systemic lupus erythematosus patients. Methods Data from a prevalent lupus cohort were used. The LFA-REAL ClinRO includes 9 domains: mucocutaneous (global and 3 subdomains), musculoskeletal (global and 2 subdomains), cardiorespiratory, neuropsychiatric, renal, hematological, constitutional, vasculitis, and other (it allows for other or rare manifestations). For each domain, a 0- to 100-mm visual analog scale is used, and global domains are included except for the mucocutaneous and musculoskeletal domains where the subdomains are included; it allows for 3 manifestations under "other,"so the score ranges from 0 to 1400 (sum of 14 in the visual analog scale). Damage was assessed with the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index. Generalized estimating equations were performed, being the outcome the increase in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index; confounders from the previous visit were included; adjusted multivariable models were done. Incidence rate ratios per 10-unit increase in the LFA-REAL ClinRO were reported. Similar models were performed to evaluate the impact of the SLEDAI-2K (SLE Disease Activity Index) and physician global assessment on damage to determine which measure would better predict damage accrual. Results Three-hundred thirty-one patients and 1425 visits were included, 1.9 (SD 1.2) years of follow-up. Disease duration at baseline was 10.7 (7.4) years. The mean LFA-REAL ClinRO was 18.2 (SD 30.7). During the follow-up visits, 63 (17.9%) patients accrued damage once; 4 (1.1%) accrued damage twice. The LFA-REAL ClinRO was predictive of damage accrual even after adjustment for possible confounders (incidence rate ratio 1.10 (95% confidence interval 1.04-1.16; p < 0.001). Similar results were obtained using the SLEDAI-2K and the physician global assessment. Conclusion The LFA-REAL ClinRO is predictive of damage accrual, even after adjusting for possible confounders.
