Meteorin-like protein (Metrnl) is a novel adipomyokine with potential immunomodulatory and anti-inflammatory properties; however, its role in spondyloarthritis remains incompletely understood. This study aims to evaluate serum Metrnl levels in patients with PsA and AS compared with healthy controls and to investigate their association with disease activity, inflammatory markers, and clinical manifestations. The findings may provide insights into the potential role of Metrnl as a biomarker of disease activity and inflammation in spondyloarthritis.",[52,53],"Ankylosing Spondylitis","Psoriasis",[55,56,57],"Ankylosing spondylitis","psoriasis","biomarker","NOT_YET_RECRUITING","2026-06-10",{"date":61,"type":62},"2026-06-15","ACTUAL",{"date":64,"type":48},"2026-07-01",{"date":66,"type":48},"2026-07-30",{"name":5,"class":6}]
