The Impact

Diabetes mellitus(DM) is a metabolic disorder characterized by hyperglycaemia and high morbidity worldwide. The detrimental effects of hyperglycaemia include an increase in the oxidative stress (OS) response and an enhanced inflammatory response. DM compromises the ability of the liver to regenerate and is particularly associated with poor prognosis after ischaemia-reperfusion (I/R) injury. Considering the growing need for knowledge of the impact of DM on the liver following a surgical procedure, this review aims to present recent publications addressing the effects of DM (hyperglycaemia) on OS and the inflammatory process, which play an essential role in I/R injury and impaired hepatic regeneration after liver surgery.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

The Impact

Background:Several studies have focused on oxidative stress on diabetes mellitus (DM). Our purpose was to investigate the impact of oxidative stress on progression of diabetic retinopathy (DR) in insulin-dependenttype 2DM patients, measuring serum malondialdehyde (MDA), as well as to examine the effect of vitamin E on DR progression in the above-mentioned patients.Methods:Participants in the study were 282 insulin-dependenttype 2DM patients with DR. All participants underwent a thorough ophthalmological examination, so as to grade DR, along with serum MDA measurement. All participants received 300mg vitamin E daily for 3 months and were examined again. Serum MDA pre- and post-intake of Vitamin E was the main outcome.Results:Serum MDA was positively associated with DR stage, while there was a statistically significant difference pre- and post-intake of vitamin E in all DR stages. In a subgroup analysis of patients with proliferative DR, there was a significant difference at baseline between patients who have received prior laser photocoagulation and the treatment naïve patients, while after intake of vitamin E, no statistically significant difference was noticed.Conclusion:Oxidative stress has been found to play significant role in the pathogenesis and progression of DR, while vitamin E seems to reduce MDA levels and subsequent oxidative stress, suggesting that it might have protective role in DR progression.

The Impact

Hyperproduction of highly active carbonyl compounds and reactive oxygen species initiates the development of oxidative stress in various pathological conditions and protein carbonylation is considered to be one of the key factors in the progression of diabetes mellitus and associated complications. This comparative research aimed to study the effect of metformin and rosuvastatin on the levels of biochemical markers of oxidative stress, glycemic control, and lipid profile in rats with type 2 diabetes mellitus (T2DM) complicated by a brain hemorrhage.T2DM was simulated with a single intraperitoneal injection of nicotinamide and streptozotocin (NA/STZ) to male Wistar rats (n=38). Intracerebral hemorrhage (ICH) was induced by microinjection of 1 μL of bacterial collagenase 0.2 IU/μL into the striatum. Animals were randomized into 5 groups: negative control, intact rats; positive control 1, NA/STZ; positive control 2, NA/STZ+ICH; metformin, 250 mg/kg +NA/STZ+ICH; rosuvastatin, 15 mg/kg+NA/STZ+ICH. Drug effects were assessed by the area under the glycemic curve (AUC), the content of glucose, glycated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), homocysteine (Hcy), advanced glycation end products (AGEs), and the markers of oxidative modification of proteins – aldehyde- and ketonephenylhydrazones (APH/KPH) in blood serum.It was found that brain hemorrhage in rats with T2DM can intensify the manifestations of oxidative modification of molecules and worsen glycemic control and lipid profile. Under these conditions, rosuvastatin improved lipid metabolism and reduced the levels of AGEs by 35.1% but did not affect glycemia and content of APH/KPH. Metformin reduced oxidative stress (AGEs by 35.4%, KPH by 21.2%) as well as improved both glycemic status and lipid profile (TG level by 20.2%, TG/HDL ratio by 31.9%). Both drugs did not produce any effect on Hcy level.Thus, metformin in conditions of T2DM complicated by acute ICH has advantages over rosuvastatin in relation to the markers of oxidative modification and glycemic control.

Abstract Background Type-1 diabetes mellitus (T1DM) causes endothelial dysfunction and early atherosclerosis, which can result in premature coronary artery disease. The aim of this study was to determine the impact of glycemic control, vascular oxidative stress and inflammation on vascular health in adolescents with T1DM. Methods This was a cross-sectional study in adolescents with age- and sex-matched T1DM who were ≥12 years and were at least 2 years post-diagnosis. Recruitment was balanced to include individuals with hemoglobin A1c (HbA1c) ≤8.5% (n=27) or with HbA1c ≥9.5% (n=25). Biomarkers of inflammation were measured in the blood including C-reactive protein (CRP), interleukin-6 (IL-6), intercellular adhesion molecule-1 (ICAM-1), E-selectin, fibrinogen and tumor necrosis factor-α (TNF-α). Carotid intima media thickness (cIMT) and peripheral arterial tonometry (PAT) were assessed. Results Plasma E-selectin level was significantly different between the two groups with higher levels in the group with HbA1c ≥9.5% (65.0±27.7 ng/mL vs. 48.8±21.5 ng/mL, p=0.02). Though cIMT and PAT were not significantly different between the groups, Pearson correlation showed a significant direct relationship between rising HbA1c and mean right cIMT (p=0.02; r=0.37), PAT (p=0.03, r=0.31) and fibrinogen (p=0.03, r=0.03). Conclusions Elevated E-selectin level is an early marker of oxidative stress in T1DM patients with an elevated HbA1c level. Suboptimal glycemic control as evidenced by a rising HbA1c causes early atherosclerosis.

ABSTRACTObjective: The aim of this study is to investigate the impact of Haematococcus pluvialis extract against oxidative stress and inflammatory cytokinesinduced by hyperglycemia in diabetic rats.Methods: Oxidative stress; lipid peroxide (as presented by Malondialdehyde; MDA) and nitric oxide (NO), beside total antioxidant capacity, enzymaticand non-enzymatic antioxidants including reduced glutathione, glutathione peroxidase, and glutathione reductase were evaluated. The inflammatorycytokines; tumor necrosis factor-alpha and interleukin-1 beta were also investigated in rats’ serum. Several analyses including expression ofantioxidant enzyme related genes, reactive oxygen species (ROS) formation and DNA adducts were performed.Results: The results showed that diabetes mellitus induced-rats exhibited increase in oxidative stress biomarkers and inflammatory cytokines, lowerexpression levels of the antioxidant enzyme genes; superoxide dismutase and glutathione S-transferase than those in control rats. In addition, diabeticrats exhibited significantly higher levels of ROS generation and 8-hydroxy-2’-deoxyguanosine (8-OHdG) formation. In contrary, supplementation ofdiabetic rats with H. pluvialis extract improved the negative effect of the hyperglycemia on antioxidant enzymes, the gene expression of antioxidantenzymes, and ROS generation as well as 8-OHdG formation.Conclusion: H. pluvialis extract decreased the oxidative stress, enhanced antioxidant status and inflammatory cytokines induced by hyperglycemiain diabetic rats. The effect of H. pluvialis extract involved in the increase of expression levels of antioxidant enzyme genes; decreased the levels of ROSgeneration and 8-OHdG formation which may be attributed to the presence of astaxanthin in H. pluvialis extract.Keywords: Haematococcus pluvialis, Hyperglycemia, Diabetes mellitus, Oxidative stress, Inflammatory cytokines, DNA adducts.

Background: Oxidative stress and the mild inflammatory process present in diabetes play a critical role in the pathogenesis of the disease and its comorbidities. This understanding has opened new avenues and targets for developing improved treatments since the risk factors associated with diabetes may be reduced through non-pharmacological interventions. In this sense, plant extracts could be efficient in preventing or assisting these pathological conditions treatment. Methods: Diabetes mellitus was induced in 24 rats, which were allocated in 4 groups: Control (CT), Control+Baccharis (CT-B), Diabetes (DB), and Diabetes+Baccharis (DB-B). For 28 days, the animals of CT-B and DB-B groups were treated, via gavage, with B. dracunculifolia extract at 50 mg.kg-1. Results: The DB group presented higher values than the DB-B group on parameters such as creatinine (26.42%), urea (31.42%), and triglycerides (60.80%). Creatinine and triglycerides values of DB-B group (0.39±0.01 e 75.0±8.4, receptively) were equivalent to the values of CT group (0.32±0.01 e 71.7±5.4) and of CT-B group (0.39±0.01, and 58.8±4.5). The treatment with B. dracunculifolia improved the levels of fasting glucose and response of glucose tolerance (32%), insulin (52,17%) and lipid peroxidation (liver 33.33%, kidney 38.77%) when compared to the DB group. Conclusions: The phenolic compounds and the anti-inflammatory activity of the extract of Baccharis dracunculifolia may be responsible for the hypoglycemic effect observed in the study.

Regular Physical Exercise

Over the last 30 years the combination of both a sedentary lifestyle and excessive food availability has led to a significant increase in the prevalence of obesity and aggravation of rates of metabolic syndrome and type 2 diabetes mellitus (T2DM). Several lines of scientific evidence have been demonstrating that a low level of physical activity and decreased daily energy expenditure leads to the accumulation of visceral fat and, consequently, the activation of the oxidative stress/inflammation cascade, which underlies the development of insulin resistant T2DM and evolution of micro, and macrovascular complications. This paper focuses on the pathophysiological pathways associated with the involvement of oxidative stress and inflammation in the development of T2DM and the impact of regular physical exercise (training) as a natural antioxidant and anti-inflammatory strategy to prevent evolution of T2DM and its serious complications.
