Objectives: To assess oxidative damage and lipid profile levels in Type 2 diabetes mellitus patients with or without tobacco chewing habit. Methods: Total of 141 newly diagnosed Type 2 diabetes mellitus patients with tobacco chewing habit from past >18 years were included, 136 Type 2diabetes mellitus without any tobacco chewing habit, 140 normal healthy subjects without any tobacco chewing habit were included in the study. Blood sample was collected after 8-12 hours fasting from each subject to estimate glucose and cholesterol. The plasma was used for estimation of total antioxidant (TAA) activity, Vitamin C and thiobarbituric acid reacting substances (TBARS) by standard methods. Statistical analysis was done with SPSS version 16. Results: The glucose, cholesterol and TBARS levels were found to be increased significantly (p<0.001) in diabetic patients with tobacco chewing habit, as well as TAA, Vitamin C levels decreased significantly (p<0.001) when compared with healthy individuals. Conclusion: We observed increased oxidative stress and declined levels of antioxidants in newly diagnosed type 2 diabetes patients with tobacco chewing habit. It is known that hyperglycemia induces oxidative stress and further facilitate the progression of diabetic complications. Bangladesh Journal of Medical Science Vol.18(1) 2019 p.78-82

Background: Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion and insulin action or both. The chronic hyperglycemia is associated with long-term damage, dysfunction, and failure of normal functioning of various organs. Hyperglycaemia generates oxidative stress and progressive inflammation due to organ damage.  In this study, we have analysed the serum levels of some oxidative and inflammatory markers and Lipid profile in newly diagnosed type 2 diabetes patients. Methods: Case-control study comprising of aged-sex matched subjects: newly diagnosed T2DM cases (n=30) and controls (n=30). The serum samples of subjects were analysed for levels of CRP by turbidimetry, MDA by Buege and Aust method, while NO levels by Cortas and Wakid’s kinetic cadmium reduction method using spectrophotometer. Lipid profile was analysed using agarose gel electrophoresis. Statistical analysis was done using Mini-tab 17 software with 95% confidence interval. Results: In comparison to healthy controls, serum levels of MDA and NO in T2DM patients were significantly increased. Serum CRP was significantly increased. The lipid profile was significantly affected with decrease in VLDL and Chylomicron, while increase in LDL levels. Levels of HDL and Lipoprotein (a) were unaffected. Conclusion: There is increased inflammatory and oxidative stress in type 2 diabetes which affects the lipid profile and dysfunction of body organs causing disease progression. Lipid profile and lipoprotein (a) analysis with antioxidant supplements might help control and keep check on disease status.

Background: Diabetes is a chronic disease and sustained hyperglycemia attacks both micro vessels and macro vessels throughout the body. It is the leading cause of retinopathy, nephropathy, end-stage renal disease, non traumatic lower extremity amputations.Subjects and Methods:Twenty five (25) Patients with newly diagnosed type 2 diabetes mellitus without any signs of retinopathy were identified from outpatient services of department of Medicine and Twenty five (25) Patients with newly diagnosed type 2 diabetes mellitus with retinopathy were identified from outpatient services of department of Ophthalmology along with 25 healthy subjects were taken as controls. Diabetic retinopathy was diagnosed after doing detailed dilated fundoscopic examination as per the standard criteria.Results:The levels of FBS, HbA1c, total cholesterol, triglycerides and MDA were significantly higher in the diabetics without retinopathy, while the HDL and Vitamin C levels were lower as compared to those of the control group. The levels of FBS HbA1c, cholesterol, triglycerides and MDA were significantly higher in the diabetics with retinopathy, while the HDL and Vitamin C levels were lower as compared to those in the diabetes without retinopathy.Conclusion: The increased oxidative stress and a decreased antioxidant status can predict the micro-vascular complications in diabetes mellitus. The raised MDA levels indicate the oxidative stress and the decreased Vitamin C levels indicate the reduced antioxidant status in diabetic retinopathy.

Type 2 diabetes mellitus (DM) is a chronic disease which deteriorates the quality of life with time. Type 2 DM accounts for more than 90% cases of diabetes mellitus as compared to other types of this disease. There is significant oxidative stress in type 2 DM which plays an important role in the pathogenesis of disease. In order to combat this oxidative stress antioxidant supplements have to be added as add on therapy along with treatment of type 2 DM. Vitamin C is the safest antioxidant which plays significant role in diminishing the oxidative stress. The vitamin C supplementation have good control of FBS and HbA1c and therefore helps in achieving better glycemic control along with prevention of lipid abnormalities.

Abstract Background: This research aimed to study the effect of coriander seed supplementation on serum glycemic indices, lipid profile and oxidative stress parameters in patients with type 2 diabetes mellitus (T2DM).Methods: In this randomized double-blinded, placebo-controlled trial, eligible 40 T2DM patients aged 30-60 years were recruited from Sina Hospital (Tabriz, Iran) and randomly assigned into two groups to receive either coriander seed powder (1000 mg/day, n=20) or placebo (1000 mg/day, n=20) for 6 weeks. Anthropometric measurements, dietary intake, and biochemical parameters including fasting blood sugar (FBS), serum insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high- and low-density lipoprotein cholesterols (HDL-C and LDL-C), malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed before and after supplementation.Results: Anthropometric measurements were not significantly different between intervention and placebo groups. Coriander seed supplementation led to significant within-group reductions in FBS (156.15±23.19 to 130.30±21.15), serum insulin (17.72±0.47 to 17.12±0.76), HOMA-IR (6.82±0.95 to 5.52±0.99), TC (183.85±55.68 to 145.20±31.36), TG (152.50±37.59 to 130.40 ±27.96), LDL-C (127.35±23.45 to 111.40±25.71), and MDA (1.65±0.15 to 1.49±0.15), whereas there were significant increases observed in serum TAC (1.93±0.12 to 1.97±0.09) (P<0.05). Post-dose comparisons showed significant between-group differences for FBS, serum insulin, HOMA-IR, TC, TG, LDL-C, MDA, and TAC levels after adjusting for baseline values (P<0.05).Conclusions: Coriander seed supplementation was able to improve glycemic indices, lipid profile and oxidative stress status in T2DM and it may be useful complementary treatment in management of these patients.Trial registration: The study protocol was registered on the Iranian Registry of Clinical Trials website (IRCT20190224042821N2) on 2019/Oct/11.

Pre-clinical studies suggested potential cardiovascular benefits of dipeptidyl peptidase-4 inhibitors (DPP4i), however, clinical trials showed neither beneficial nor detrimental effects in patients with type 2 diabetes mellitus (T2DM). We examined the effects of DPP4i on several circulating oxidative stress markers in a cohort of 32 T2DM patients (21 males and 11 post-menopausal females), who were already on routine antidiabetic treatment. Propensity score matching was used to adjust demographic and clinical characteristics between patients who received and who did not receive DPP4i. Whole-blood reactive oxygen species (ROS), plasma advanced glycation end products (AGEs), advanced oxidation protein products (AOPP), carbonyl residues, as well as ferric reducing ability of plasma (FRAP) and leukocyte DNA oxidative damage (Fpg sites), were evaluated. With the exception of Fpg sites, that showed a borderline increase in DPP4i users compared to non-users (p = 0.0507), none of the biomarkers measured was affected by DPP4i treatment. An inverse correlation between estimated glomerular filtration rate and AGEs (p < 0.0001) and Fpg sites (p < 0.05) was also observed. This study does not show any major effect of DPP4i on oxidative stress, assessed by several circulating biomarkers of oxidative damage, in propensity score-matched cohorts of T2DM patients.

Background: Diabetes mellitus is rising all over the world due to population growth, aging, urbanisation, and the increase of obesity due to physical inactivity, characterized by persistent high blood glucose levels associated with aberrations in lipid, carbohydrate, and protein metabolisms leading to water and electrolyte imbalance. Cardiovascular diseases are the leading causes of mortality in diabetic patients. Mechanisms such as oxidative stress, lipid metabolism imbalance, as well as myocardial cell apoptosis are key factors to facilitate the progression of Diabetic cardiomyopathy. Aim: The aim of this study was to assess FGF-21 levels and their association with lipid profile parameters and oxidative stress in patients with type 2 diabetes mellitus. Methods: A patient based cross-sectional study was conducted among the subjects with history of type 2 DM for the past 10 years. Results: Variations in FBS, T.C, TG, LDL, HDL, VLDL, FGF-21, MDA and AOPP levels among cases and controls were depicted in Table 2. There was an increase in all these parameters in cases compared to controls whereas HDL showed a decrease among cases. Conclusion: Our study concluded that there is a significant correlation between fibroblast growth factor 21 (FGF-21), oxidative stress, and abnormal lipid profile in type 2 diabetic patients. We would recommend further studies to explore the role of FGF21 as an important marker in predicting cardiovascular risk in diabetic patients.

ABSTRACT Introduction: Diabetes mellitus is accompanied by increased formation of reactive oxygen species (ROS) and decreased antioxidant capacity, leading to oxidative damage to cellular components. There is evidence to suggest that regular physical training positively changes oxidative homeostasis in the cells and tissues by lowering basal levels of oxidative damage, increasing resistance to oxidative stress. Objective: To verify the possible effects of aerobic physical training and resistance on glycemia and oxidative metabolism, and to determine whether there is any difference in outcomes resulting from different types of training in sedentary people with Type 2 Diabetes Mellitus (T2DM). Methods: A systematic review of controlled and randomized trials based on PRISMA. The databases LILACS, IBECS, Pubmed/MEDLINE, Cochrane Library, SciELO, PEDro, ScienceDirect and BIREME were searched, combining the descriptors type 2 diabetes mellitus, resistance training, aerobic exercise and oxidative stress in Portuguese, English and Spanish. The methodological quality of the papers was assessed by the PEDro scale. The data were read, analyzed, extracted and summarized. Results: Of the 1386 papers retrieved, only five met the inclusion criteria. The five selected papers, consisting of controlled and randomized clinical trials, were summarized. Conclusion: There have been many published studies reporting on exercises and diabetes. However, there is limitation when it comes to comparing their results. The variability of research methods and measurement instruments used makes it difficult to draw conclusions as to which physical training modality is most effective in reducing glycemic levels and oxidative stress in sedentary individuals with T2DM, considering that in each study analyzed in this review, the response to these variables is different. In future research, it would be important to standardize exercise modality, intensity, training time and evaluation parameters. Level of evidence I; Systematic review of RCTs (Randomized controlled trials).
