Background: Free radicals are reactive oxygen species which cause lipid peroxidation precipitating many metabolic diseases including Diabetes Mellitus. However, these free radicals are quenched by substances known as antioxidants like vitamin C, vitamin E and several other compounds. Lipid peroxidation and antioxidant status were investigated in patients with Type 1 and Type 2 Diabetes mellitus- Pokhara, Nepal.Methods: The extent of lipid peroxidation was assessed by thiobarbituric acid reactive substances and the antioxidant parameter estimations were total antioxidant activity, Vitamin C and Vitamin E assessed in Type 1 and 2 diabetes mellitus patients along with matched healthy counterparts.Results: The lipid peroxidation was increased in male Type 1 and 2 diabetic patients whereas female group showed decreased level as compared to its healthy counterparts. Similarly, the total antioxidant activity was found to be decreased in the diabetic group. The lipid peroxidation parameter and antioxidant status were statistically significant at p< 0.05.Conclusion: Oxidative stress and antioxidant status varied in male and female patients suffering from diabetes either Type 1 or Type 2. Apart from gender basis of evaluating oxidative stress, variables based on diet, habitat, socioeconomic status, education, etc. can also be considered.MED Phoenix Volume (1), Issue (1) July 2016, page: 10-14

 Objective: To evaluate the total antioxidant status (TAS) and the extent of DNA strand breaks (damage) as a measure of oxidative stress biomarkers in Type 2 diabetic patients (with and without complications) and controls.Materials and Methods: Blood samples were collected from 200 patients with type 2 diabetes mellitus (n=100 with complications and n=100 without complications) and 100 healthy individuals. Oxidative DNA damage was evaluated using alkaline single cell gel electrophoresis (comet assay). Total antioxidant status was assessed by Ferric Reducing Ability of Plasma (FRAP) assay.Results: TAS was found to be significantly lower in type 2 diabetic patients (with and without complications) compared to controls (p< 0.001).  Similarly, patients with complications of type 2 diabetes mellitus had significantly lower TAS when compared to diabetic patients (p= 0.007). DNA damage analysis showed that the extent of damage was high in patients with diabetes mellitus (with and without complications) compared to controls (p< 0.001). Fasting glucose and glycosylated haemoglobin level (HbA1c) was found to be significantly higherin diabetic patients than controls (p< 0.05). Correlation analysis showed that there is no association between age, duration, sugar level, HbA1c, TAS and DNA damage in patients with Type 2 diabetes mellitus.Conclusion: Alterations in TAS and the extent of DNA damage was observed in patients with complications of diabetes mellitus indicate that oxidative stress is more in patients with complications when compared to patients without complications and healthy individuals. Therefore, further DNA damage and onset of complications in Type 2 diabetes mellitus could be prevented by counteracting the oxidative stress by therapeutic interventions using appropriate antioxidants.Key words: Hyperglycemia, Oxidative stress, DNA damage, Total antioxidant status, Type 2 diabetes mellitus, Vascular complication

The aim of the study was to investigate the association between lipid peroxidation and antioxidant status in nonobese type 2 diabetes mellitus (T2DM) and further to correlate whether their significant association is putatively associated with the pathogenesis of T2DM. A number of 102 nonobese T2DM subjects and 95 nondiabetic subjects as healthy controls were enrolled in this cross-sectional study. Serum samples were collected in cryovials for malondialdehyde (MDA) and thiol assays. Total thiol or sulfhydryl (–SH) groups in peripheral blood mononuclear cells (PBMCs) and sera, as well as level of MDA, a marker for lipid peroxidation in serum, were measured spectrophotometrically. Serum MDA level was found significantly higher whereas serum and PBMC total thiol levels were diminished significantly among nonobese T2DM subjects compared to HC subjects. Moreover, serum MDA level is found to have a significant inverse correlation with serum total thiol and PBMC thiol levels among DM subjects, but no significant correlation was observed in HC individuals. A significant inverse correlation between serum MDA and serum total thiol levels among nonobese T2DM subjects suggests a close association of increased oxidative stress with decreased antioxidant status in nonobese T2DM.

Indians are more susceptible to diabetes mellitus (DM) because of genetic reasons & improper life-style habits. Currently, the occurrence of DM has been prevalent in youngsters especially in  India, in our present study, we attempted to explore the role of oxidative stress,  inflammation in first degree relatives of type 2 diabetes mellitus (FDRDM). Inflammation was assessed by using high sensitive C reactive protein (hsCRP), Interleukin 6 (IL6),  Tumor necrosis factor-alpha (TNF alpha), and oxidative stress by using malondialdehyde and total antioxidant status. FDRDM and control groups had similar for age, height, and waist-hip ratio (WHR). Weight and body mass index (BMI) was significantly high in  FDRDM.  Total antioxidant levels (TAOS) were less, and malondialdehyde (MDA) was significantly more in the FDRDM group. Inflammatory markers were significantly high in FDRDM.  We conclude that increased oxidative stress and inflammation may lead to more derangements in glucose homeostasis in first degree relatives of type 2 diabetes (T2DM), it could increase the chances of development of cardiac events and necessitates early lifestyle modifications.

Background: Diabetes mellitus has emerged as one of the most common health hazard all over the world. Diabetic nephropathy is the most challenging long term complication of Type 2 Diabetes mellitus and microalbuminuria is the earliest marker of diabetic nephropathy. In diabetes, chronic hyperglycemia and deranged lipid profile lead to excess generation of free radicals. The increased oxidative stress plays a major role in pathogenesis of diabetic complications, including diabetic nephropathy. There are many naturally occurring antioxidant enzymes in our body. Diabetes has multiple effects on protein levels and activity of these antioxidant enzymes. This further augments the oxidative stress. There are many non-enzymatic antioxidants in our body which include vitamins A, C, E and trace minerals like copper, zinc, manganese and selenium.Methods: The study was done on a total of 150 subjects. Group A comprised of 60 Type 2 diabetic patients with diabetic nephropathy, Group B comprised of 60 Type 2 diabetic patients without diabetic nephropathy and Group C comprised 30 healthy controls. Total antioxidant status, microalbuminuria and glycosylated haemoglobin were measured.Results: In present study, authors found that total antioxidant status is drastically reduced in all diabetic patients, and it was found to be further low in patients with diabetic nephropathy. This decrease was found to be directly proportional to the degree of diabetic nephropathy, as measured by the levels of microalbuminuria.Conclusions: Timely institution of antioxidant supplementation therapy may emerge as a promising measure in delaying the onset and progression of diabetic complications, especially diabetic nephropathy.

Dietary Total Antioxidant Capacity

Abstract This work aims to examine the interaction between Apolipoprotein A2 (Apo A-II) −265T>C single nucleotide polymorphism (SNP) and dietary total antioxidant capacity (DTAC) on inflammation and oxidative stress in patients with type 2 diabetes mellitus. The present cross-sectional study included 180 patients (35-65 years) with identified Apo A-II genotype. Dietary intakes were assessed by a food frequency questionnaire. DTAC was computed using the international databases. Interleukin-18(IL18), high-sensitivity C-reactive protein (hs-CRP), and pentraxin (PTX3), serum total antioxidant capacity (TAC), superoxide dismutase activity (SOD), and 8-isoprostaneF2α (PGF2α) markers were obtained according to standard protocols. General linear model was used to evaluate the interaction. The interaction of gene and DTAC (PFRAP=0.039 and PORAC=0.042) on PGF2α level was significant after adjusting for confounders. A significant interaction was observed on IL18 level (PORAC=0.018 and PFRAP=0.048) and SOD (PTEAC=0.037) in obese patients. Among patients whose DTAC was higher than the median intake, the levels of hs-CRP and PGF2α were significantly higher only in individuals with CC genotype. Serum TAC (PFRAP=0.030, PORAC=0.049) and SOD were significantly lower in the CC genotype. There was a favorable relationship between the high-DTAC and SOD (Obese: PTEAC=0.034, Non-obese: PFRAP=0.001, PTRAP<0.0001, PTEAC=0.003 and PORAC=0.001) and PGF2α (Non-obese: PORAC=0.024) in T-allele carriers. The rs5082 SNP interacts with DTAC to influence several cardio-metabolic risk factors. Also, we found dietary recommendations for antioxidant-rich foods intake might be useful in the prevention of diabetes complications in the T carrier more effectively than the CC genotype. Future large studies are required to confirm these results.
