Background/aim: Thiol-disulfide homeostasis is an important antioxidant defense mechanism. This study was conducted to investigatedynamic thiol-disulfide homeostasis in patients with hepatitis B virus-related chronic hepatitis and liver cirrhosis.Materials and methods: Seventy-one treatment-naive patients with chronic hepatitis B (CHB), 50 patients with hepatitis B virusassociated liver cirrhosis, and 45 healthy controls were included in the study. Serum total and native thiol concentrations and serumdisulfide concentrations were measured using an automated method.Results: Mean serum total thiol concentrations in the control, CHB, and cirrhosis groups were 481.64 37.87 µmol/L, 438.50 71.35µmol/L, and 358.07 80.47 µmol/L, respectively (P 0.001), and mean serum native thiol concentrations in the control, CHB, andcirrhosis groups were 452.92 36.43 µmol/L, 400.16 65.92 µmol/L, and 328.15 74.91 µmol/L, respectively (P 0.001). Mean serumdisulfide concentrations in the control, CHB, and cirrhosis groups were 14.38 3.38 µmol/L, 19.19 6.16 µmol/L, and 14.98 5.53µmol/L, respectively (P 0.001). There was a progressive decrease in both mean serum native and total thiol concentrations parallel tothe liver fibrosis stage.Conclusion: : Thiol-disulfide homeostasis is disturbed in patients with hepatitis B virus-related chronic hepatitis and liver cirrhosis.
