Abstract. Background: The pathophysiological basis of chronic kidney disease and its complications, including cardiovascular disease, are associated with chronic inflammation and oxidative stress. We investigated the effects of active vitamin D (calcitriol) and synthetic vitamin D analog (paricalcitol) on oxidative stress in hemodialysis patients. Methods: This cross-sectional study was composed of 83 patients with a minimum hemodialysis vintage of one year. Patients with a history of any infection, malignancy, and chronic inflammatory disease were excluded. Oxidative markers (total oxidant and antioxidant status) and inflammation markers (C-reactive protein and interleukin-6) were analyzed. Results: A total of 47% (39/83) patients were using active or analog vitamin D. Total antioxidant status was significantly higher in patients with using active or analog vitamin D than those who did not use (p = 0.006). Whereas, total oxidant status and oxidative stress index were significantly higher in patients with not using vitamin D when compared with the patients who were using vitamin D preparation (p = 0.005 and p = 0.004, respectively). On the other hand, total antioxidant status, total oxidant status, and oxidative stress index were similar between patients who used active vitamin D or vitamin D analog (p = 0.6; p = 0.4 and p = 0.7, respectively). Conclusion: The use of active or selective vitamin D analog in these patients decreases total oxidant status and increases total antioxidant status. Also, paricalcitol is as effective as calcitriol in decreasing total oxidant status and increasing total antioxidant status in patients with chronic kidney disease.

Oxidant Status

Gastroesophageal reflux disease (GERD) is a global health problem in which the prevalence is increasing over periods. This disease is a significant cause of disorders in the upper gastrointestinal tract with very complex pathogenesis. Oxidative stress (OS) due to gastric acid reflux plays a role in the inflammatory response of the esophageal epithelium. Several OS markers have been widely studied and are thought to affect the severity degree of the esophageal mucosa. However, there has been no research on total oxidant status (TOS), total antioxidant status (TAS), and OS index (OSI) in the adult with GERD; hence the aim of this review was to determine the association between TOS, serum TAS, and OSI with the GERD degree. A literature review was conducted by searching articles related to the TOS, TAS, OSI, and its correlation with GERD degree on an online database, particularly Pubmed and Google scholar. We conclude that TAS and OSI might influence the severity of GERD; however, further clinical study is needed to prove this theory.

Objective: Carbon monoxide poisoning (COP) is one of the important causes of morbidity and mortality in toxicological cases. In this study, we aimed to find out more about the pathophysiology of COP by investigating the effects of COP on oxidative stress parameters such as total oxidant status (TOS) and total antioxidant status (TAS). Methods: Eighty-eight patients admitted to the emergency department of our hospital with acute COP and 35 healthy adults as control group were included in this study. Blood samples were collected from all COP patients at the time of initial emergency department evaluation to determine the oxidative stress parameters. Then, serum levels of total antioxidant status and total oxidant status levels were measured. Results: A total of 88 patients poisoned by carbon monoxide (CO; mean age 37.1 ± 18.2 years; 54’% women) were enrolled. TOS and carboxyhemoglobin (COHb) levels in COP patients were increased when compared to control group (p = 0.001). TOS, oxidative stress index (OSI) and COHb levels in COP patients were significantly lower after the treatment. (respectively, p = 0.016; p = 0.023; p = 0.001). On the other hand, no statistical differences were observed in TAS levels of study and control group as well as there were no changes with treatment. Conclusion: Measurements of TOS, TAS and OSI levels may be useful markers to find out the pathophsiology of COP.

Plants are important antioxidant sources. In our study, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of endemic Helleborus vesicarius Aucher ex Boiss.were determined. The aerial parts of the plant samples were dried and extracted with ethanol (EtOH). TAS and TOS values of plant extract were determined using Rel Assay Diagnostics kits. As a result of the studies, the TAS value of H. vesicarius was determined 5.548±0.23, the TOS value was 13.778±0.119 and the OSI value was 0.249±0.009. In this context, the plant has been shown to have significant antioxidant potential.

AbstractObjectiveOxidative stress refers to an imbalance between reactive oxidative species and antioxidants. In this case-controlled, prospective, observational study, we investigated the total oxidant status, total antioxidant status, oxidative stress index, and albumin and C-reactive protein levels of children with cyanotic and acyanotic congenital heart diseases who had undergone on-pump cardiac surgery.MethodThe study groups consisted of 60 patients with congenital heart disease, who were operated under cardiopulmonary bypass, and a control group of 30 healthy individuals. The patients were classified into two groups. Among them, one was a patient group that consisted of 30 patients with acyanotic congenital heart disease and the other group consisted of 30 patients with cyanotic congenital heart disease. In the patient groups, blood samples were collected before surgery and at one and 24 hours following surgery. In control groups, blood samples were collected once during hospital admission.ResultsNo statistically significant differences were found between the groups in terms of baseline total oxidant status, total antioxidant status, and oxidative stress index values. Regarding the postoperative first-hour and 24-hour total oxidant status and total antioxidant status levels as well as oxidative stress index values, there were no significant differences between the groups, except for an increase in total antioxidant status levels (p=0.002) 24 hours after surgery in cyanotic patients.ConclusionThere was no difference between oxidative stress status of cyanotic and acyanotic congenital heart disease patients and healthy individuals. Oxidative stress status of cyanotic and acyanotic patients does not change after cardiac surgery under cardiopulmonary bypass.
