Novel oxidative stress biomarker in sepsis: dynamic thiol-disulfide homeostasis
Abstract
Purpose: The aim of this study was to investigate the relationship between serum dynamic thiol-disulfide homeostasis (TDH) and sepsis, in adult patients.
Materials and Methods: In this observational, prospective, case-control study patients (n=44) diagnosed with sepsis compared with ages and gender-matched healthy controls (n=44). Patients were divided into two subgroups (survivors and non-survivors) dependent variable being remaining alive on the 28th day after ICU admission at the follow-up period. TDH parameters measured using a novel automatic and spectrophotometric method and compared statistically.
Results: In patients with sepsis, native thiol, total thiol, and disulfide levels were lower than the control group, and this difference was statistically significant. TDH parameters between surviving and non-surviving patients were similar at the sepsis diagnosis. However, significant differences found in native and total thiol levels at follow-up via repeated measurement analyses on days 3 and 7 in surviving and non-surviving sub-groups.
Conclusion: This study showed that impairment in dynamic TDH in adults with sepsis may be related to negative outcomes.
