Immunological and oxidative stress biomarkers in Ankylosing Spondylitis patients with or without metabolic syndrome.

Ankylosing Spondylitis (AS) is a chronic inflammatory disorder of the spine and sacroiliac joints with unidentified etiology closely associated with metabolic syndrome (MetS). Recent studies have reported that immunological and oxidative stress factors are implicated in AS pathogenesis. The aim of this study was to investigate the oxidative and immunological factors in AS patients with or without MetS compare to control group.
