Background: It is possible that patients with pneumonia may also have sepsis and the separation of these two clinical entities may cause some trouble to clinicians.

Objective: In order to separate a patient with pneumonia and a patient with sepsis, we qualify thiol/disulfide homeostasis as a potential biomarker.

Methods: This study was designed between February 2018 – February 2019 prospectively. All patients in the intensive care unit with pneumonia and sepsis were enrolled in the study. At the time of hospitalization, thiol/disulfide homeostasis was measured. Patients diagnosed with sepsis and pneumonia were compared, in regards to thiol/disulfide homeostasis.

Results: During research period, 103 patients with sepsis and 120 patients with pneumonia were enrolled into the study. When we compared native-thiol, total-thiol, and disulfide levels in both sepsis and pneumonia patients, we had similar results (p>0.05). In sepsis group, index-1 (disulfide/native thiol ratio) and index-2 (disulfide/total thiol ratio) were found to be statistically higher than the pneumonia group, and index-3 (native thiol/total thiol ratio) was statistically lower than the pneumonia group (p=0.020, p= 0.021, p=0.021, respectively).

Conclusion: In this study, we showed that thiol/disulfide homeostasis could be used as new markers in the early period in order to separate patients with sepsis and patients with pneumonia.

Keywords: Thiol/disulfide homeostasis, sepsis, pneumonia, intensive care unit, infection, mortality.
