The aim of this study was to determine the effectiveness of thiol-disulfide homeostasis in predicting diagnosis and mortality in sepsis patients, and to compare it with other inflammatory markers.

Sepsis is a serious illness with high mortality rates triggered by infection-associated pathogenesis involving oxidative stress dysfunction. This study aims to elucidate the diagnostic efficacy of changes in thiol-disulfide homeostasis, its predictive role in mortality, relationship with other inflammatory parameters in sepsis patients in emergency department.

In prospective, randomized controlled study, 50 patients diagnosed with sepsis according to the Sepsis-3 guidelines who presented emergency department were compared with a control group of 50 healthy volunteers. Thiol-disulfide homeostasis parameters, including total thiol, native thiol, disulfide levels, reduced thiol, oxidized thiol, and thiol oxidation-reduction ratios, were examined. Additionally, inflammatory blood parameters (C-reactive protein, procalcitonin, lactate) and mortality durations were compared with thiol-disulfide homeostasis.

The objective of this study was to examine the effectiveness of thiol-disulfide homeostasis in forecasting diagnosis and mortality in sepsis patients, and to compare it against other inflammatory markers.
