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.

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.

The present study aimed to look for the differences in the oxidative stress status in sera and saliva samples of type 2 diabetic Iraqi patients with and without proliferative diabetic retinopathy. As well as to look for the possibility whether this status can be measured in saliva as an alternative sample to that of serum, hence to achieve that total oxidant status, total antioxidant status and oxidative stress index were measured in both sera and saliva samples of two groups of patients with type 2 diabetes mellitus and the healthy individuals. Upon the comparison between patients without proliferative diabetic retinopathy and the control sample the results showed presence of a significant increase (p < 0.05) of total oxidant status and oxidative stress index in sera and saliva samples, while there was a significant decrease (p < 0.05) in total antioxidant status of sera and saliva samples. Meanwhile when the comparison was done between patients with proliferative diabetic retinopathy and those without proliferative diabetic retinopathy, a significant increase (p < 0.05) in both salivary total oxidant status and oxidative stress index was observed with a significant decrease (p < 0.05) in sera and salivary total antioxidant status were found in the proliferative diabetic retinopathy patients group.
