Abstract
Background: Long-term studies characterizing disease course of cutaneous lupus erythematosus (CLE) patients on standard-of-care treatments are lacking. Objective: We characterized and compared disease course of CLE patients using Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI). Methods: In total, 83 CLE patients with CLASI scores collected from ≥3 study visits within 2 years had disease activity and damage trends calculated by average change scores (ACS). Trends were classified as improved (ACS ≤−3), worsened (ACS ≥3), or stable (–3 < ACS < 3). Linear regression models compared CLASI trends between groups. Results: Most patients (72.73%) with initial CLASI activity (CLASI-A) scores >9 (N = 33) had improved disease activity versus 14.00% of those with initial CLASI-A scores ≤9 (N = 50). Linear regression analyses showed significant improvement in CLASI-A scores in patients of minority races (P <.05), with baseline CLASI-A scores >9 (P <.0001), baseline CLASI damage (CLASI-D) scores ≥10 (P =.0001), and CLE disease duration ≤1 year (P =.01). Of 28 patients with baseline CLASI-D scores ≥10, 35.71% had improvements in damage, while 5.26% of patients with initial CLASI-D scores of 5-9 (N = 19) and 0% with initial CLASI-D scores <5 (N = 36) (P =.0005) had improvements. Limitations: Limitations include small sample size. Conclusion: Baseline CLASI-A score >9, minority race, and short disease duration predict CLE disease activity improvement. A baseline CLASI-D score ≥10 is associated with disease damage improvement.
