Evaluation of serum TWEAK , TRAIL, and oxidative stress markers in rosacea patients

Rosacea is a chronic inflammatory skin disease of unknown pathogenesis. TWEAK and TRAIL are two cytokines thought to have a role in the pathogenesis of some inflammatory and autoimmune diseases.The purpose of this study was to examine TWEAK and TRAIL serum levels and oxidative stress markers in patients with rosacea.Forty rosacea patients and 40 sex- and age-matched healthy controls were involved in the study. Serum TWEAK and TRAIL levels were evaluated with ELISA kits. Serum total antioxidant status, total oxidant status, total thiol, native thiol, disulfide levels were evaluated, and oxidative stress index was computed.Serum levels of TWEAK, TRAIL, and oxidative stress markers did not differ statistically in the patients and controls. Both TWEAK and TRAIL levels in the patients were detected to be statistically higher in male than in female.TWEAK and TRAIL may not have a systemic effect in rosacea, unlike other inflammatory diseases. More studies are needed to investigate the role of TWEAK and TRAIL in rosacea.
