Baseline Cutaneous Lupus Erythematosus Disease Area and Severity Index activity (CLASI-A) >9, minority race, and shorter disease duration predict cutaneous lupus erythematosus (CLE) disease activity improvement. This according to a recent study in which researchers characterized and compared the disease course of CLE patients using CLASI. 83 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. They found:
- 72.73% with initial CLASI activity (CLASI-A) >9 (n=33) had improved disease activity vs 14.00% with initial CLASI-A ≤9 (n=50).
- Linear regression analyses showed significant improvement in CLASI-A scores in patients with baseline CLASI-A >9, baseline CLASI damage (CLASI-D) ≥10, minority races, and CLE disease duration ≤1 year.
- 35.71% with baseline CLASI-D ≥10 (n=28) had improving disease damage vs 5.26% with initial CLASI-D=5-9 (n=19) and 0% with initial CLASI-D <5 (n=36).
