ABSTRACT

Background and objectives: Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disorder affecting 30% of psoriatic patients. Effective treatment, especially with biologics like IL-17 and TNF inhibitors, is vital for improving patient outcomes. This study aimed to compare the efficacy of secukinumab and adalimumab in PsA patients through clinical and ultrasonographic evaluations.Materials and methods: We enrolled 116 PsA patients, with 58 patients receiving secukinumab and 58 receiving adalimumab. Regular follow-ups were conducted at weeks 4, 12, 24, and 52. The primary outcome was the proportion of patients achieving at least a 20% improvement in the ACR response (ACR20) at week 12, with additional evaluations for axial arthritis, enthesitis, skin involvement, minimal disease activity, health assessment questionnaire, and ultrasound changes.Results: There was no significant difference in ACR20 response between the two groups at week 12 (OR: 0.59, 95% CI: 0.26-1.37, p = 0.22). However, secukinumab demonstrated superior efficacy in achieving Psoriasis Area and Severity Index (PASI)90 (OR: 2.25, 95%CI: 1.07-4.74, p = 0.03), while adalimumab showed better improvement in ultrasound synovitis count (β: 0.94, 95%CI: 0.09-1.79, p = 0.03) and synovitis PD signal (β: 0.20, 95%CI: 0.03-0.36, p = 0.02).Conclusions: In conclusion, both treatments were highly effective for PsA, with secukinumab being more suitable for severe skin involvement and adalimumab for significant ultrasound-confirmed synovitis.
