dc.description.abstractAim: Polycythemia vera is a chronic myeloproliferative disease characterized by increased red cell mass and JAK2 mutation positivity. Transformation to myelofibrosis and acute leukemia is possible in patients with polycythemia vera. Oxidative stress causes DNA damage and might be a reason for malignant transformation. Thiol molecules can prevent the harmful effects of oxidative stress. Therefore, in this study, we aimed to analyze the state of thiol homeostasis in patients with polycythemia vera. Material and Methods: Thirty-one patients with polycythemia vera and 80 healthy volunteers were included in this study. Serum samples of the cases were stored until the end of the study. Native thiol, total thiol, disulfide, and ischemia modified albumin levels were determined. Results: The mean ischemia modified albumin (1.09±0.21 vs 0.67±0.08; p<0.001, mean disulfide (23.5±6.1 vs 10.7±2.6; p<0.001), the mean disulfide/native thiol ratio (5.6±1.1 vs 3.1±1.2; p<0.001), the mean disulfide/total thiol ratio (5.0±0.9 vs 2.9±1.0; p<0.001), the mean native thiol (418.9±80.6 vs 371.4±103.7; p=0.024), the mean total thiol (466.0±89.8 vs 393.0±105.5; p=0.001) and the mean disulfide/total thiol ratio (89.8±1.8 vs 94.1±2.0; p<0.001) were found higher in polycythemia vera patients. Ischemia modified albumin levels were also higher in high-risk polycythemia vera patients. Patients on ruxolitinib therapy had higher native thiol, total thiol and disulfide levels, and higher disulfide/native thiol and disulfide/total thiol ratios. Conclusion: Oxidative stress markers are still high in patients with polycythemia vera who were under treatment. Besides, ruxolitinib may be helpful to decrease oxidative stress in these patients.en_US
