Abstract
CONCLUSION: It is thought that oxidative stress may be the major cause of the increase in the oxide thiol form in the study group. The relationship between oxidative stress status and dynamic thiol/disulphide in nasal polyposis now needs to be investigated.
OBJECTIVES: The purpose of this study was to evaluate the relation between nasal polyposis and thiol/disulphide homeostasis, used as a marker of oxidative stress, by measuring that exchange using a novel technique.
MATERIALS AND METHODS: The study group consisted of 40 patients (mean age = 46.75 ± 13.92 years) with bilateral nasal polyposis patients admitted to the hospital. The control group consisted of 31 (mean age = 43.20 ± 5.68 years) age, sex, and body mass index matched healthy subjects. Thiol/disulphide homeostasis concentrations were measured using a newly-developed method (Erel & Neselioglu).
RESULTS: Native thiol and total thiol levels were lower in the study group compared to the control group (native thiol = 415.8 ± 69.1 μmol/L vs 448.7 ± 37.5 μmol/L, p < 0.05; total thiol = 449.02 ± 72.0 μmol/L vs 477.28 ± 44.5 μmol/L, p < 0.05, respectively). Disulphide level and the disulphide/native thiol and disulphide/total thiol ratios were higher in the study group compared to the control group (disulphide = 16.58 ± 5.04 μmol/L vs 14.28 ± 5.3 μmol/L, p < 0.05; disulphide/native thiol ratio = 4.07 ± 1.52% vs 3.14 ± 1.04%, p < 0.05, disulphide/total thiol ratio = 3.73 ± 1.23% vs 2.94 ± 0.92%, p < 0.05, respectively).
