Objective: The purpose of this study was to understand the relationship between oxidative stress markers malondialdehyde (MDA), antioxidant Vitamins A, E, and C and the glycated hemoglobin levels with Type 2 diabetes mellitus. Methods: The current study is a cross-sectional study group, comprised no diabetic individuals (100 healthy) as control groups and diabetic patients (300) as cases groups, attending the Khartoum - Sudan for routine follow-up during 2013–2015. The data were collected with the help of structured questionnaire and direct interview to collect information. Blood specimens were collected from both groups, and plasma levels of MDA, serum zinc, antioxidant Vitamins (A, E, and C), and glycated hemoglobin (HbA1c) were determined. Odds ratio and the 95% confidence interval (95% CI) were calculated for the presence of mutation between cases and controls and analyzed by SPSS program, version 13. Results: The results of this study indicate a highly significant difference between the means of HbA1c% of the test group (n=300) and the control group (n=100). Mean ± SD: 7.5 ± 1.4 versus 4.9 ± 0.3, respectively (p=0.001). Significant positive correlation between HbA1c and MDA (p=0.003). Significant correlation between HbA1c% and plasma Vitamins A, E, and C of the test group, respectively (p=0.002), (p=0.0008), and (p=0.01). Conclusion: There was significant correlation between HbA1c% with Malondialdehyde (MDA) and antioxidant Vitamins (A, C, and E).

Background: Diabetes Mellitus (DM) is a progressive metabolic disorder. Objective: The aim of this study was to investigate the relationship between antioxidant and oxidative stress markers in the saliva of patients with type 2 DM and a healthy control group. Methods: In this study, 20 patients with diabetes and 20 healthy individuals were evaluated. Salivary antioxidants markers consisted of total antioxidant capacity (TAC), uric acid (UA), peroxidase and catalase. Oxidative stress markers included total oxidant status (TOS), malondealdehyde (MDA) and total thiol (SH). Sialochemical analysis was performed with spectrophotometric assay. All the statistical analyses were conducted using STATA software. Results: TAC decreased significantly in patients with diabetes. Although salivary UA and peroxidase were lower in patients with diabetes compared to the control group, the difference was not significant. Salivary catalase in patients with diabetes was significantly lower than that in the control group. MDA and TOS exhibited significantly higher levels in type 2 DM. SH levels were slightly higher in DM. Conclusions: According to the results of the present study, there were some changes in the salivary levels of some antioxidants and oxidative stress markers in patients with type 2 DM and could be measured as an indicator of serum changes..

Epidemiological studies associate milk consumption with an increased risk of Parkinson’s disease (PD) and type 2 diabetes mellitus (T2D). PD is an α-synucleinopathy associated with mitochondrial dysfunction, oxidative stress, deficient lysosomal clearance of α-synuclein (α-syn) and aggregation of misfolded α-syn. In T2D, α-syn promotes co-aggregation with islet amyloid polypeptide in pancreatic β-cells. Prion-like vagal nerve-mediated propagation of exosomal α-syn from the gut to the brain and pancreatic islets apparently link both pathologies. Exosomes are critical transmitters of α-syn from cell to cell especially under conditions of compromised autophagy. This review provides translational evidence that milk exosomes (MEX) disturb α-syn homeostasis. MEX are taken up by intestinal epithelial cells and accumulate in the brain after oral administration to mice. The potential uptake of MEX miRNA-148a and miRNA-21 by enteroendocrine cells in the gut, dopaminergic neurons in substantia nigra and pancreatic β-cells may enhance miRNA-148a/DNMT1-dependent overexpression of α-syn and impair miRNA-148a/PPARGC1A- and miRNA-21/LAMP2A-dependent autophagy driving both diseases. MiRNA-148a- and galactose-induced mitochondrial oxidative stress activate c-Abl-mediated aggregation of α-syn which is exported by exosome release. Via the vagal nerve and/or systemic exosomes, toxic α-syn may spread to dopaminergic neurons and pancreatic β-cells linking the pathogenesis of PD and T2D.
