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.

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

Introduction: Zn supplementation improved glutathione peroxidase enzyme activity and decreased malondialdehyde and nitric oxide levels in diabetic rats, revealing Zn's defensive effect against oxidative stress in type 2 diabetes. The investigators have discovered that consuming Zn increased liver function and protected pancreatic tissue from damage caused by diabetes. Since Zn also prevents chronic hyperglycemia, it helps to minimize oxidative stress caused by type 2 diabetes. Diabetes mellitus (DM) is a global health problem that affects more than 3 million people worldwide (16% of population). Chronic hyperglycemia causes oxidative stress in diabetic patients by the development of free radicals (oxidants) and lowering the antioxidant protection mechanism. Aim: Glycaemic Regulation with Zinc Combination in Type 2 Diabetes Mellitus. Materials and Methods: Faculty of Medicine and Diabetic Opd, Datta Meghe Mediсаl Соllege and Shаlinitаi Meghe Hоsрitаl аnd Reseаrсh Сenter, Nаgрur in соllаbоrаtion with Dаttа Meghe Institute оf Mediсаl Sсienсes Deemed to be University, Sаwаngi, Wаrdhа, Mаhаrаshtrа. Results: The mean Zn level was 12.213±2.342in all participants and 9.121±1.782 in the control group, whereas it was significantly low (9.121±1.782) in the diabetic group, and there was statistically significant difference in Zn levels between the controls and the diabetic group (P < 0.001).FBS, HbA1C, serum Zinc mean effects between control and patients showed statistically significant differences in type 2 diabetes mellitus (P <0.0001). Conclusion: Our findings show that people with diabetes have lower levels of Zn than healthy people. The cause and effect of the association between very low levels of Zn and the progression of diabetes, or diabetes that causes Zn deficiency, is still unknown. Low levels of Zn are associated with poor glycemic control, and poor glycemic control is a good indication of Zn deficiency, as there was a negative association between serum Zn and FBS and HBA1C. If diabetic patients have low glycemic regulation, a long history of diabetes, obesity, or are over the age of 50, we look to assess their levels in Zn so that Zn alternative treatment can begin to release oxidative stress in this high-risk group.

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.

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.
