Assessment of Glycemic Control, Renal Function, and Oxidative Stress Parameters in Type 2 Diabetes MellitusPatients

Diabetes mellitus (T2DM) is a multifactorial syndrome that israpidly rising in all the continents ofthe globe, causing elevated blood sugar levels in affected people. A sample of 81 Iraqi T2DM patients was investigated based on several parameters. Glycemic control parameters includedlevels of fasting blood glucose (FBG),glycated hemoglobin (HbA1C), and insulin, along with insulin resistance (IR) and insulin sensitivity (IS). Renal function tests includedmeasuring the blood levels of urea and creatinine. Oxidative stress parameters included total antioxidant capacity (TAC) and thelevel of reactive oxygen species (ROS). The results of the presentstudy showed a highly significant (P˂0.01) increase in FBG, HbA1c, insulin and IR levels in T2DM patients as compared to control.Insulin sensitivity showed a highly significant (p˂0.01) decrease in patients compared with control.Urea and creatinine levelsincreased in T2DM patients, but the differences were insignificant. TAC levelsignificantly (P<0.05) increased in patients compared with control. Also, the levels of ROSrevealed a highly significant (P<0.01) increasein T2DM patients compared with the control. Correlation analysis showedthat FBG has a highly significant (P<0.01) positive correlation with IR, urea, creatinine and ROS, as well as a significant (P<0.05) positive correlation with TAC. However, FBG shows a highlysignificant (P< 0.01) inverse correlation with IS. The levels of HbA1C show a significant (P<0.05) positive correlation with IR, creatinine, and TAC, whereas ithas a highly significant (P<0.01) positive relation with ROS. However, HbA1C level has a highly significant (P<0.01) inverse relation with IS. Insulin has highly significant (P<0.01) positive and negative associations with IR and IS, respectively.IR showshighlya significant (P<0.01) inverse correlation with IS, significant (P<0.05) positive correlation with creatinine, and highly significant (P<0.01) positive correlation with ROS. IS has a significant(P< 0.05) inverse correlation with urea. Urea shows a highly significant (P<0.01) positive correlation with creatinine. TAC has a significant (P<0.05) inverse correlation with ROS. Conclusion: diabetic patients revealed poor glycemic control. Fluctuating blood glucose concentrations may contribute significantly to oxidative stress, probablyeven more than chronic hyperglycemia. The observed significant positive correlation between FBG and the other tested parameters revealed that hyperglycemia is an obvious independent risk factor for T2DM progression.

Introduction: Evidence has long existed regarding the relationship between oxidative stress and diabetes. The present study was conducted to assess the effect of atorvastatin on selected oxidative stress parameters in the form of reduced glutathione (GSH), lipid peroxidation byproduct malondialdehyde (MDA) levels, glutathione –S- transferase (GST) activity and catalase (CAT) activity) and its effect on lipid profile (total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) in dyslipidaemic type 2 diabetic patients . Materials and Methods: Fifty nine dyslipidaemic type 2 diabetic patients were included in this study. Full history was taken and general examination of patients was performed. Patients studied were taking glibenclamide (an oral hypoglycaemic drug) during the study as a treatment for their disease. These patients were followed up for 60 days and divided randomly into 2 groups. Group I (n = 31): no drug was given and served as dyslipidaemic diabetic control. Group II (n = 28): received atorvastatin tablets 20 mg once daily at night. Of the 59 Fifty patients, 46 completed the study while 13 patients withdrew. This is due to non compliance of the patients. Blood samples were drawn from the patients at the beginning and after 60 days of follow up between 8:30 & 10:30 am after at least 12-14 hours fast. Fasting blood glucose, lipid profile, selected oxidative stress parameters (GSH, MDA levels, GST and CAT activities) were measured. Renal and hepatic functions were also assessed. Results: This study revealed that: atorvastatin treatment increased serum GSH; reduced MDA levels significantly while did not significantly affect CAT and GST activity. In atorvastatin treatment, TC, TG, LDL and VLDL decreased significantly while HDL increased significantly. Conclusion: There was insignificant correlations between atorvastatin induced changes in the oxidation markers and the observed changes of the lipid profile.

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.

AIMS: Evidence shows that diabetic patients may be predisposed to oxidative stress owing to increased glyco-oxidation and lipid peroxidation processes in consequence of chronic hyperglycemia. However, there is dearth of information whether glycemic control positively affects the antioxidant defense system in type 2 diabetes mellitus (T2DM). We investigated the potential association between glycemic control and oxidative stress biomarkers in controlled and uncontrolled diabetic states. METHODS: After obtaining ethical clearance, we included patients receiving metformin with glycated hemoglobin A1c ˂7.0% (glycemic control); newly diagnosed T2DM patients without glycemic control with hemoglobin A1c ˃7.0%; and apparently healthy normoglycemic individuals. The following biomarkers were determined: fasting glycemia level, malondialdehyde, glutathione peroxidase activity, catalase activity, total antioxidant capacity and total cholesterol level. The comparisons between the groups were made by ANOVA. RESULTS: The participants were 260 in number: 80 with controlled diabetes, 80 uncontrolled and 100 controls. All participants were between 40 and 71 years old. Fasting glycemia level and hemoglobin A1c showed significant reductions (p<0.05) in controlled T2DM against the uncontrolled T2DM group, all the same both were significantly higher (p<0.05) against the controls. Likewise, malondialdehyde levels showed significant elevations (p<0.05) correspondingly in both uncontrolled and controlled T2DM against the controls, accompanied with significant reductions (p<0.05) in the antioxidative enzyme activities (glutathione peroxidase activity and catalase activity) and total antioxidant capacity levels against the controls. In addition, total cholesterol was significantly reduced (p<0.05) in controlled T2DM against both uncontrolled T2DM and controls, respectively. There were significant correlations between hemoglobin A1c and oxidative stress biomarkers (p<0.05). CONCLUSION: There was no remarkable difference in oxidative stress states between glycemic controlled and uncontrolled T2DM, despite differences in their fasting glycemia and glycated hemoglobin levels. Our data, therefore, suggest that chronic hyperglycemia and possibly anti-diabetic medicationmay both equally associate with oxidative stress.

The black cumin (Nigella sativa) “NS” or the black seeds have many pharmacological activities such as antioxidant, anticarcinogenic, antihypertensive, and antidiabetic properties. In this work, streptozotocin-induced diabetic rats fed with a high-fat diet were treated daily with NS oil (NSO) in order to study the effect on the blood glucose, lipid profile, oxidative stress parameters, and the gene expression of some insulin receptor-induced signaling molecules. This treatment was combined also with some drugs (metformin and glimepiride) and the insulin receptor inhibitor I-OMe-AG538. The administration of NSO significantly induced the gene expression of insulin receptor compared to rats that did not receive NSO. Also, it upregulated the expression of insulin-like growth factor-1 and phosphoinositide-3 kinase, whereas the expression of ADAM-17 was downregulated. The expression of ADAM-17 is corroborated by the analysis of TIMP-3 content. In addition, the NSO significantly reduced blood glucose level, components of the lipid profile, oxidative stress parameters, serum insulin/insulin receptor ratio, and the tumor necrosis factor-α, confirming that NSO has an antidiabetic activity. Thus, the daily NSO treatment in our rat model indicates that NSO has a potential in the management of diabetes as well as improvement of insulin-induced signaling.
