Analysis of Influence Factors on Osteopenia in Different Treatment of Psoriasis

Psoriasis is a chronic, immune-mediated inflammatory skin disease associated with increased systemic inflammation, which may contribute to altered bone metabolism and decreased bone mineral density (BMD). Several studies have reported an elevated risk of osteopenia and osteoporosis in patients with moderate-to-severe psoriasis. The pathophysiological mechanisms may involve pro-inflammatory cytokines, such as TNF-α and IL-17, which influence both skin inflammation and bone remodeling.

Biologic therapies targeting these cytokines have demonstrated significant efficacy in managing psoriasis. However, their long-term impact on bone metabolism and density is still under investigation. Secukinumab, an IL-17A inhibitor, and Adalimumab, a TNF-α inhibitor, are both widely used in clinical practice, but their comparative effects on bone health are unclear.

This prospective, observational, real-world study aims to evaluate the longitudinal changes in BMD (lumbar spine and hip) and bone turnover markers (such as osteocalcin, P1NP, CTX, and iPTH) in psoriasis patients undergoing treatment with Secukinumab or Adalimumab over a follow-up period of XX months. Participants will undergo baseline and follow-up assessments, including dual-energy X-ray absorptiometry (DEXA) and laboratory testing for bone biomarkers.

Key endpoints include:

Changes in BMD at lumbar spine and hip from baseline.
