Most nutrition studies looking at the association of food with cardiometabolic markers rely on food frequency questionnaires, which are prone to recall bias. Pentadecanoic acid, heptadecanoic acid and trans-palmitoleic acid are fatty acids that are not synthesized endogenously but are obtained from the diet, particularly dairy, making them reasonable biomarkers of dairy consumption. We investigated the association of dairy fatty acid biomarkers with glycated hemoglobin (HbA1c) and cardiovascular risk factors in type 2 diabetes (T2D). In a clinical trial, 111 participants with T2D (age 58.5 ± 8.9 years, HbA1c 8.09 ± 0.96%) were randomized into three groups: a control group that maintained baseline dairy intake, a low-fat (LF) group that incorporated ≥3 servings/day of LF dairy and a high-fat (HF) group that incorporated ≥3 servings/day of HF dairy. We compared the fatty acids (FA) composition between the three groups at 24 weeks. Pentadecanoic acid and trans-palmitoleic acid increased in the HF group by 14.1% ± 5.4% and 17.5% ± 5.1%, respectively, but not in the control and LF groups (p = 0.0474 and p= 0.0025 for group-by-time interaction, respectively). Those increases were positively associated with changes in total cholesterol, very-low-density lipoprotein cholesterol VLDL-C and triglycerides but were not associated with changes in HbA1c from baseline to 24 weeks. These results suggest that the intervention was successful and that participants were likely compliant, which supports the validity of the main trial.

Gamma-oryzanol is a component of rice bran oil (RBO) with purported health benefits. This study evaluated the effects of gamma-oryzanol on insulin resistance and lipid metabolism in Wistar rats with type 2 diabetes (T2DM). The rats were divided into three groups and consumed one of the following diets for 5 weeks: 15 % soybean oil (control group); 15 % palm oil (PO); and 15 % PO with the addition of 5.25 g gamma-oryzanol (POO). The results showed that PO markedly increased plasma low-density-lipoprotein cholesterol, plasma triglycerides, and hepatic triglyceride levels, but did not reduce the area under the curve for glucose and insulin significantly, compared with the control group. Adding gamma-oryzanol to PO improved the negative influence of PO on lipid metabolism in T2DM rats. In addition, gamma-oryzanol tended to increase insulin sensitivity in T2DM rats compared to control and PO groups. Longer-term studies are needed to evaluate these effects further.

Background: Diabetes is an endocrine disorder that is strongly associated with cardiovascular disease. The use of alternative therapy has recently increased and medicinal plants are one of the alternative therapies for diabetic patients. This study aimed to evaluate the protective effect of Urtica dioica (Nettle) on lipid profile in patients with type 2 diabetes (T2D). Method: This parallel randomized double-blinded clinical trial was conducted on 60 men and women with T2D for an 8-week period. The participants were randomly assigned to received 100mg/kg/day extract of Urtica Dioica (UG) and the placebo group (PG). Blood triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDLc) and high density lipoprotein cholesterol (HDLc) were measured at baseline and end of the study. The data were analyzed using SPSS 16.0 and P < 0.05 was considered significant. Results: The mean difference of total cholesterol showed no significant difference in the UG compared to the PG which were -10.56±40.5 and -19.5± 35.9 (P = 0.14), respectively. The study also showed no significant difference between TG and LDLc in the UG compared to the PG (-39.8±171.5 vs. -23.37±72.3 (P = 0.68) and -3.16±33.4 vs. -11.2±35.6 (P = 0.15), respectively). The mean difference of HDLc in the UG and PG were -2.68±8.11 and 2.62±10.6 (P = 0.05), respectively, indicating a significant increase in the UG compared to the PG. Conclusion: The results demonstrated that consumption of 100mg/kg/day extract of UD for 8 weeks by increasing HDL concentration can decrease the risk of cardiovascular disease in patients with T2D.

Hedysarum polybotrys polysaccharide (HPS) is the principal active fraction responsible for the antidiabetic properties of this species. The aim of this study was to determine the antidiabetic properties of 4 purified fractions of different molecular weight range HPSs (HPS1, HPS2, HPS3, HPS4). HPS3 was selected for examination of its hypoglycemic mechanism because of its significant hypoglycemic effect in alloxan-induced diabetic mice. The changes in blood glucose levels and oral glucose tolerance tests (OGTT) showed that hypoglycemia was more pronounced in HPS3-treated groups than in the diabetes mellitus model (DM) control group. The interleukin-6, tumor necrosis factor-α, leptin, and free fatty acid levels were significantly lower in the HPS3-treated groups and HPS3 + metformin (HPS3+MET) group than in the DM control group, while plasma insulin, hepatic glycogen, superoxide dismutase, and nitric oxide synthetase activity were significantly higher. Treatment with HPS3 or HPS3+MET also significantly lowered malonaldehyde levels compared with the DM control group, while it elevated the nitric oxide and total antioxidant capacity. HPS3 altered the plasma lipid levels by lowering cholesterol and triglyceride concentrations, while elevating the plasma high-density lipoprotein cholesterol level. Therefore, these results suggest that HPS3 may partly ameliorate hyperglycemia and hyperlipidemia associated with type 2 diabetes through increased insulin secretion, inhibition of lipid peroxidation, promotion of sensitivity to insulin, suppression of gluconeogenesis and reduction in the biosynthesis fatty acid, cholesterol and cell cytokines related to insulin resistance, and it could be a useful adjunct therapy to a proven first-line therapy for type 2 diabetes using metformin.

Abstract Background: Asprosin, a newly identified adipokine, is pathologically increased in individuals with insulin resistance. However, the available evidence on the association of asprosin and type 2 diabetes mellitus (T2DM) status is still scarce. Therefore, this study aimed to determine the relationship between serum concentrations of asprosin and T2DM status . Methods: This observational study was performed based on 194 adults (97 newly diagnosed T2DM and 97 healthy individuals). Anthropometric and biochemical variables were determined in all participants . Serum concentrations of asprosin were measured using enzyme-linked immunosorbent assay (ELISA). Results: In patients with T2DM, the serum concentrations of asprosin were significantly higher than the healthy controls (4.18 [IQR: 4.4] vs. 3.5 [IQR: 1.85], P< 0.001). The concentrations of asprosin were significantly correlated with body mass index (BMI) and fasting blood glucose (FBG) in healthy subjects and with BMI, FBG, hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), and quantitative insulin check index (QUICKI), triacylglycerol (TAG) and total cholesterol/ high-density lipoprotein cholesterol (TC/HDL-C) ratio in the T2DM group. In fully adjusted model, the odds ratio (OR) of T2DM with serum concentrations of asprosin was approximately 1.547 (95% CI 1.293-1.850, P< 0.001) compared to the control group . Multiple stepwise regression analysis indicated that FBG and HOMA-IR were independently associated with asprosin in T2DM. Conclusion : Our findings indicated that serum concentrations of asprosin are increased in patients with T2DM. Also, asprosin is correlated with insulin resistance and TC/HDL-C ratio (atherosclerotic risk factor of cardiovascular diseases) in patients with T2DM.

Objective: to evaluate the effectiveness of ginge (Zingiber officinale) in reducing blood sugar and lipid levels in people with type 2 diabetes. Method: a randomized and double-blind clinical trial conducted with people with type 2 diabetes in primary care facilities. The study included individuals aged between 20 and 80 years old, using oral antidiabetic drugs and with HbA1c levels between 6.0% and 10%. The participants were paired 1:1, allocated in two distinct groups, and randomized in blocks, based on their HbA1c levels. In the experimental group, the participants used 1.2g of ginger and, in the control group, 1.2g of placebo, daily for 90 days. The primary outcome was a reduction in fasting blood sugar and HbA1c, and the secondary outcome was a reduction in lipids and HOMA-IR. 103 individuals completed the study, 47 in the experimental group and 56 in the control group. Results: the participants in the experimental group showed a greater reduction in the blood glucose and total cholesterol values compared to the control group. Conclusion: the use of ginger can help in the treatment of people with diabetes, and data support the inclusion of this herbal drug in the clinical practice of nurses. RBR-2rt2wy

Aim. To evaluate effects of metabolic disorders on the risk of cardiovascular death in patients with type II diabetes based on Framingham risk score. We analyzed results of examination of 210 men and 210 women with type 2 diabetes who applied for medical care to the VM center of Endocrinology during 1997-2014. A virtual control group was formed matching real patients in terms of the number, sex, age, and height having ideal body mass index, total cholesterol and high-density lipoprotein cholesterol levels. The average risk of cardiovascular death in patients with type 2 diabetes was equal to 4,56±0,254% compared with 0,6±1,028% in the virtual control group. The differences was significant (p <0,001). The minimum risk for the patients of the two groups was estimated at 0,001% and 0,01% respectively. The maximum risk of cardiovascular death is 34,17% in patients with diabetes and 8,24% in controls. It is concluded that type 2 diabetes and related metabolic disorders significantly increase the risk of cardiovascular death.

Objectives: The present study aimed to investigate the potential effects of the combined herbal capsule (CHC), as a nutritional supplement, on glycemic indices (GIs) and lipid profile (LP) of patients with type 2 diabetes mellitus (T2DM). Methods: Following a randomized, single-blind, placebo-controlled clinical trial, the current study was conducted on 80 cases with T2DM who were randomly assigned into two groups of treatment (CHCs; n = 40) and control (placebo; n = 40). Both groups received the intervention (500 mg capsules) twice a day for three months, without changes in the previous dose of oral anti-hyperglycemic drugs. The GI and LP levels were measured before the intervention and three months later to investigate the potential efficacy of the interventions. Results: For those in the intervention group, the mean GI [i.e., fasting blood sugar, two hours postprandial (2hpp), and HbA1c] was significantly different after 3 months (P < 0.05). The GI- and LP-related outcomes (TG, LDL-C except for TC) were improved after 3-month of receiving the intervention compared to the control group; however, the observed improvement was no statistically significant (P > 0.05). The HDL-C level was also significantly improved in the intervention group compared to the control group (P < 0.05). Conclusions: This study demonstrated that receiving CHCs could improve GI and LP levels (TG, LDL-C, and HDL-C, except for TC), which indicates its potential to control T2DM. Moreover, no significant side effect was observed in the intervention group. It can be argued that the use of CHCs, as adjuvant therapy, in combination with conventional hypoglycemic and lipid-lowering drugs, as well as following a modified lifestyle, not only can significantly enhance glycemic control but also may prevent T2DM complications.

Introduction. Currently, there is no unified treatment algorithm of cardiac autonomic neuropathy (CAN) in patients with type 2 diabetes mellitus (T2DM). The aim of the study was to investigate the effects of simvastatin (SIM) and -3 polyunsaturated fatty acids (-3 PUFAs) on blood lipid profile and insulin resistance (IR) in patients with type 2 diabetes mellitus and definite cardiac autonomic neuropathy. Materials and methods. The study involved 72 patients with T2DM and definite CAN. Patients were divided into four groups: 1st - received standard hypoglycemic therapy - control (n = 15); 2nd (n = 22) – in addition simvastatin (SIM) 20.0 mg/q.d.; 3rd (n = 18) - in addition 1 capsule/q.d. of the ω-3 PUFAs; 4th (n = 17) - in addition SIM 10.0 mg/q.d and 1 capsule/q.d of the ω-3 PUFAs for three months. The concentration of glucose, glycated hemoglobin A1c, immunoreactive insulin (IRI), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG) in the blood were determined. Homeostasis model assessment IR (HOMA-IR), atherogenic coefficient (AC), TG/LDL-C, TG/TC, TG/LDL-C and TG and glucose index (TyG) were calculated. Results. Prescription of SIM was accompanied by a statistically significant decrease in TC, LDL-C, TG concentrations. In parallel, SIM induced a decrease of AC, TG/HDL-C, increase in HDL-C, and does not affect the IRI, HOMA-IR, TG/LDL-C, TG/TC, TC/LDL-C/HDL-C, TyG. The use of ω-3 PUFAs has contributed to a significant reduction in TG, AC, TG/LDL-C, TG/TC, TG/HDL-C, TyG index, increase in HDL-C, and was not accompanied by changes in IRI content, HOMA-IR, TC, LDL-C, and TC/LDL-C/HDL-C. The combined prescription of SIM and -3 PUFAs was accompanied by more pronounced, statistically significant changes in the blood lipid spectrum, as well as a decrease in the IRI and HOMA-IR. Conclusions. Obtained results justify the appropriateness of combined simvastatin and -3 polyunsaturated fatty acids prescription to patients with type 2 diabetes mellitus and definite cardiac autonomic neuropathy. Keywords: diabetes mellitus, cardiac autonomic neuropathy, treatment.
