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.

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.

Background and Objective. Oxidative stress is believed to play a role in the development of preeclampsia (PE). It is known that an increased cystatin C level is also associated with PE. The aim of this study was to investigate the relationship between oxidative stress parameters and cystatin C levels in patients with severe PE. Material and Methods. Forty-four patients with severe PE and 40 healthy pregnant women were recruited for the study. All study subjects were divided into 2 groups: group 1 (n=44) consisted of patients with severe PE, and group 2 (n=40) included healthy pregnant subjects. Blood samples were obtained from all subjects in order to measure the cystatin C level, total antioxidant status, and total oxidant status. The oxidative stress index was calculated. Results. The group 1 had significantly higher cystatin C, total oxidant status, oxidative stress index levels and lower total antioxidant status level as compared with the group 2 (P=0.001, P<0.001, P<0.001, P=0.036, respectively). The serum cystatin C level was significantly correlated with the oxidative stress index (r=0.609, P<0.001). Conclusions. The present study demonstrated that both oxidative stress and cystatin C levels were increased in patients with PE, and the increased cystatin C levels seem to be a consequence of oxidative stress.

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.

Aim: The aim of this study was to assess the antioxidant effects of aqueous, ethanolic and methanolic extracts of Morus mesozygia Linn. Stapf. Twigs in Streptozotocin-Induced Diabetic Rats. Study Design: The study is an experimental case-controlled study. Place and Duration of Study: This study was carried out at the Biochemistry Research Laboratory, University of Port Harcourt, Rivers State, Nigeria, between June, 2018 and April, 2019. Methodology: A total of 65 male albino rats that weighed between 150g to 200g were used for this research study. Three different extracted solvents; aqueous, ethanolic and methanolic twig extracts were administered to different groups of the rats. The male albino rats for this study were induced with a single dose of 40mg/kg b.wt, intraperitoneally of streptozotocin in 0.1M of citrate buffer, pH 4.5. The diabetic male rats were those whose fasting blood glucose (FBG) were from 250mg/dl or 13mmol/L and above. They were then divided into different groups and treated with different concentrations of aqueous, ethanolic and methanolic extracts of the plant material. At the end of treatment period, the rats were kept on fasting for 6 hours prior to the process of euthanasia, they were sacrificed and blood samples were collected through cardiac puncture for analysis into lithium heparin bottle for the estimation of oxidative stress markers, malondaldehyde (MDA), total oxidant status (TOS), oxidative stress index (OSI), and antioxidant enzymes, superoxide dismutase (SOD), total antioxidant capacity (TAS). Statistical analysis was done using GraphPad prism (version 6.1) software. Data generated were represented as mean and standard deviations (Mean ±S. D). Level of significant at Tukey’s Multiple Comparative Test was tested at p<0.0001. Charts were made possible with the application of Minitab version 2019. Results: The results showed that there were significant increases in the levels of superoxide dismutase (SOD, 414.2±1.30) ng/ml, total antioxidant status (TAS, 82.97±7.71) mU/ml, total oxidant status (TOS, 355.02± 14.02) mU/ml activity, a reduced oxidative stress index of 4.29±0.26 and concentration of malondialdehyde (MDA of 18.67± 0.26mmol/L) when rats were treated with 400mg/kg of aqueous leaves of Morus mesozygia Linn. S. When compared with those of rats treated with 200mg/kg of aqueous leaf extracts of MMLS. there was a significant increases and decreases respectively. Other methods of extractions (methanolic and ethanolic), also improved the antioxidant statuses of the diabetes induced and treated rats after treatment of the extracts. Conclusion: The three extracts of Morus mesozygia Linn. S showed tremendous antioxidant effects against Streptozotocin-induced diabetic rats, with the methanolic extract showing the most potent effect.
