Markers Of Oxidative Stress

We studied lipid and carbohydrate metabolism, markers of oxidative stress (plasma malonic dialdehyde and dienoic conjugates) and vascular wall damage (CRP, microalbuminuria, blood desquamated endotheliocytes) before and after 12 week treatment of obese pre-diabetic patients. The study showed positive dynamics of the above metabolic parameters with normalization of carbohydrate metabolism in 60% of the patients and angioprotective effect ofprescribed therapy. The proposed treatment can be used to prevent diabetes mellitus.

Objective: Diabetes mellitus is associated with increased prevalence of oral diseases for which reactive oxygen species have been implicated. The saliva contains protective antioxidants which statutorily curtail these destructive oxygen molecules. A functional compromise of the antioxidants may precipitate oxidative stress leading to the increased oral disease susceptibility. However, salivary markers of oxidative stress have not been sufficiently studied in the diabetics. Methods: A total of 166 adults were recruited for this study. They comprised of 95 Type 2 diabetic patients and 71 healthy non-diabetic controls. About 3 ml of unstimulated saliva samples were collected from participants and processed, levels of salivary H2O2, NO and MDA were measured using spectrophotometry method and compared between the two groups. Data was analysed using t-test, logistic regression and receiver operating characteristics (ROC) with statistical significance set at p<0.05. Results: Salivary H2O2 (p=0.024) and NO (p=0.002) were significantly higher in the diabetic patients when compared to the healthy non-diabetic control group. Binary logistic regression showed that patients with Type 2 diabetic mellitus are more likely to have elevated salivary H2O2 (OR= 1.013; p=0.025) and NO (OR=1.016; p=0.003) levels. ROC analysis showed statistically significant performance of salivary NO levels in distinguishing between T2DM patients and healthy controls. Conclusions: Higher levels of oxidative stress markers including salivary H2O2 and NO in the diabetic groups could be a pointer to the characteristic high prevalence of oral diseases in diabetes mellitus, given that oxidative stress predisposes to disease vulnerability. This calls for increased attention to oral health in diabetes management to minimise co-morbidity.

BACKGROUND Diabetes mellitus is associated with increased prevalence of oral diseases. Reactive oxygen species have been implicated in the development of these diseases. The saliva contains a balanced proportion of protective antioxidants and reactive oxygen species, disrupting this balance favours disease development. However, level of salivary markers of oxidative stress has not been sufficiently studied in the diabetics. OBJECTIVE Thus, this study aimed to measure salivary H2O2, NO and MDA in diabetic patients in comparison to non-diabetic controls. METHODS A total of 166 adults comprising of 95 Type 2 diabetic patients and 71 healthy non-diabetic controls were recruited for this study. About 3 ml of unstimulated saliva samples were collected from participants after rinsing their mouth with clean water. Levels of H2O2, NO and MDA were measured in all saliva samples using spectrophotometry. Data was analysed using t-test, logistic regression and receiver operating characteristics (ROC) with statistical significance set at p<0.05. RESULTS Salivary H2O2 (p=0.024) and NO (p=0.002) were significantly higher in the diabetic patients when compared to the healthy non-diabetic control group. Binary logistic regression showed that patients with Type 2 diabetic mellitus are more likely to have elevated salivary H2O2 (OR= 1.013; p=0.025) and NO (OR=1.016; p=0.003) levels. ROC analysis showed statistically significant performance of salivary NO levels in distinguishing between T2DM patients and healthy controls. CONCLUSIONS Higher levels of salivary H2O2 and NO could be a pointer to the high prevalence of oral diseases in diabetes mellitus. This calls for increased attention to oral health in diabetes management.

Preliminary Study

This study was aimed to assess the effectiveness of diabetes self-management education (DSME) in the improvement of glycemic control among patients with type 2 Diabetes Mellitus (T2DM) in Batticaloa District, Sri Lanka. The study was a prospective interventional study and conducted as a preliminary study at medical clinic, Base hospital, Kaluwanchikudy, Batticaloa. Thirty patients with T2DM were included based on inclusion and exclusion criteria. A structured individual diabetes self-management education for 10 hours (one hour per week) was delivered to diabetic patients by the trained Nurse Health Educator. Glycosylate hemoglobin (HbA1c) was assessed as a main outcome measure and Fasting Blood Sugar (FBS), Body Mass Index (BMI) of each patient were also measured and recorded before and after the intervention. The respondent rate was 96.7% (n = 29). Majority of them were females (n = 25, 86.2%). A Wilcoxon signed rank test showed that DSME had a statistically significant reduction in HbA1c [8.60 (IQR 2.60) vs. 7.40 (IQR 2.10), p = .000] and FBS level [159.00 (IQR 77.50) vs. 134.00 (IQR 40.50), p = .002] at 3 months of intervention. The mean BMI at baseline was higher compared to 3 months of intervention [24.88 (SD ± 3.06) vs. 24.19 (SD ± 2.79)] which was statistically significant (p = .000). Majority of participants (n = 22, 75.9%) had improved their HbA1c level by ≥ 0.5% in 3 months. The diabetes self-management education is an effective measure in improving glycemic control and other clinical parameters among patients with T2DM. Thus, DSME needs to be implemented among clinic patients with T2DM for the better outcome and the preventions of complications.

The Significance of Urinary Markers in the Evaluation of Diabetic Nephropathy Oxidative stress is considered to be a unifying link between diabetes mellitus (DM) and its complications, including nephropathy (DN). The aim of this study was to determine the parameters of oxidative injury of lipids and proteins as well as the activity of ectoenzymes in the urine of DN patients. The study included 40 individuals: 10 patients with type 2 diabetes mellitus and microalbuminuria (DMT2-MIA), 10 type 2 diabetic patients with macroalbuminuria (DMT2-MAA), 10 patients with type 1 diabetes and microalbuminuria (DMT1-MIA) and 10 age- and sex-matched healthy subjects (control). In the urine we determined TBA reactive substances (TBARS), reactive carbonyl groups (RCG), and the activity of ectoenzymes N-acetyl-β-d-glucosaminidase (NAG), plasma cell differentiation antigen (PC-1), aminopeptidase N (APN) and dipeptidyl peptidase IV (DPP IV). A higher concentration of TBARS in the urine was found in DMT2-MIA and DMT1-MIA, compared to the control group (p<0.001 and P<0.05). The urine concentration of RCD shows similar results with a significant elevation in the groups with DMT2-MAA and DMT1-MIA, compared to the DMT2-MIA (p<0.001) and control group (p<0.001). Activities of NAG, APN and DPPIV were significantly higher in the urine of DMT2-MAA, compared to the control (p<0.01). The activity of PC-1 was slightly increased in that group, but not significantly. In conclusion, the level of oxidative stress markers and activities of brush border ectoenzymes in the urine may be a useful non-invasive and easily repeatable test in DN.

Diabetes mellitus is a disease that required good self-management. Noncompliance in diet and meal plans cause the instability of blood glucose levels. Nutrition education calendar method can improve knowledge and ability to consume food that matches the number, hours and types with dietary adjustments listed in the calendar diet. This study aimed to determine the effect of nutrition education calendar method on blood glucose levels of patients with type 2 diabetes mellitus in Community Health Center Pakis Malang. Pre-experimental design one group pretest-posttest with purposive sampling was conducted in this study and sample obtained as many as 21 people. Blood glucose levels were measured before and after the nutrition education calendar methods. Compliance in using calendar method with the observation sheet. Statistical analysis values obtained by Wilcoxon, the p-value of 0.007 (p <0.05). The results of the analysis, 16 respondents showed a decrease in blood glucose levels and 5 respondents experienced an increase in blood glucose levels after the given intervention. It can be concluded that there are differences between blood glucose levels before and after nutrition education calendar method. Differences in blood glucose levels can be influenced by controlling diet respondent in accordance with the calendar method in education, but also antidiabetic drugs, and sports. Should be added to the control group to determine objectively the effect of nutrition education on the calendar method.

Purpose: The purpose of this study was to determine the effects of diabetic complications on oxidation of proteins, lipids, and DNA and to investigate the relationship between oxidative damage markers and clinical parameters. Methods: The study group consisted of 69 type 2 diabetic patients (20 patients without complication, 49 patients with complication) who attended internal medicine outpatient clinics of Istanbul Education and Research Hospital and 19 healthy control subjects. In serum samples of both diabetic patients and healthy subjects, 8-hydroxy-2’deoxyguanosine (8-OHdG), as a marker of oxidative DNA damage, Nε-(hexanoyl)lysine (HEL) and 15-F2t-iso-prostaglandin (15-F2t-IsoP). as products of lipooxidative damage, advanced oxidation protein products (AOPP), as markers of protein damage, and paraoxonase1 (PON1) as antioxidant were studied. Results: 15-F2t-IsoP (p < 0.005) and AOPP (p < 0.001) levels were significantly higher in diabetic group than control group while there were no significant differences in levels of 8-OHdG and HEL between the two groups. AOPP (p < 0.001) and 8-OHdG (p < 0.001) were significantly higher in diabetic group with complications compared to diabetic group without complications. Conclusions: Increased formation of free radicals and oxidative stress, under conditions of hyperglycaemia, is one of the probable causes for evolution of complications in diabetes mellitus. Our study supports the hypothesis that oxidant/antioxidant balance is disturbed in diabetic patients.

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.
