Disulfide / total thiol (%), disulfide / native thiol (%), and native thiol / total thiol (%) rates were calculated using the previously determined concentrations of disulfides, native thiols, and total thiols. <br /> <b>Results: </b>Of thiol / disulfide homeostasis parameters, native thiol, total thiol, and disulfide levels were statistically lower in the CHB patient group (p <0.05). As a result of the correlation analyses, a significant negative correlation was determined between HBV DNA levels and disulfide / native thiol, disulfide / total thiol, and native thiol / total thiol parameters (p <0.05). <br /> <b>Conclusions: </b>Our results suggest that oxidative stress increases with the rise in HBV-DNA levels and that the antioxidant defense may have weakened.}, number={4}, publisher={MEDİTAGEM Ltd.
