Seronegative spondyloarthropathies (SpA) are a group of chronic diseases, characterized by axial inflammation, oligoarthritis, and enthesitis. Oxidative stress may contribute to a wide range of diseases such as rheumatologic diseases including SpA. This prospective case-control study was designed to compare the thiol-disulfide levels as a marker of oxidative stress in SpA patients with healthy controls. ⋯ Thiol-disulfide balance is disturbed in favor of disulfide in SpAs patients compared to healthy volunteers. Native and total thiol measurements correlate with acute phase reactants and might be used to monitor disease activity. Anti-TNF therapy might control the oxidative degenerative process better than the classical DMARD in SpA patients.
