Purpose Type 2 diabetes mellitus (T2DM) is a worldwide health problem. Blood pressure (BP) and inflammation are well-established risk factors for the cardiovascular complications of T2DM. Genistein is known to improve endothelial dysfunction. The purpose of this study is to investigate the effects of genistein supplementation on BP, high-sensitive C-reactive protein (hs-CRP) and homocysteine (Hcy) levels in postmenopausal women with T2DM. Design/methodology/approach This randomized, double-blind, placebo-controlled clinical trial is conducted on postmenopausal women with T2DM. A total of 54 subjects aged between 47 and 69 years are divided into two groups. Participants in the genistein group (n = 28) are given two genistein capsules (each capsule contained 54 mg genistein) and those in the placebo group (n = 26) received two placebo capsules (each capsule contained 54 mg maltodextrin) daily for 12 weeks. General characteristics, BP, hs-CRP and Hcy levels are measured at the baseline and at the end of the trial. Findings Genistein supplementation resulted in a significant reduction in systolic BP (SBP) (p < 0.001), diastolic BP (DBP) (p = 0.020), mean arterial pressure (MAP) (p < 0.001), serum levels of hs-CRP (p = 0.005) and Hcy (p = 0.001) in genistein group compared with placebo group at the end of the study. Significant decreases are also found in SBP by 5.4%, p < 0.001, DBP by 6.7%, p < 0.001, MAP by 6.2%, p < 0.001, serum levels of hs-CRP by 47.0%, p = 0.015 and Hcy by 18.4%, p < 0.001 in the genistein supplemented group. No significant changes are observed in terms of all post-intervention values in the placebo group. Originality/value Genistein administration improved BP, hs-CRP and Hcy levels in postmenopausal women with T2DM and may be useful in control of some CVD risk factors in these subjects.

BackgroundPrevious studies showed altered angiopoietin-like protein-8 (ANGPTL-8) and resistin circulating levels in type 2 diabetes mellitus (T2DM). Whether or not the alteration in ANGPTL-8 and resistin level can be a predictive maker for increased diabetic nephropathy risk remains unclear.AimTo Investigate the possible association of ANGPTL-8 and resistin with DN, and whether this association is affected by NAFLD status.MethodsA total of 278 T2DM patients were enrolled. Serum levels of ANGPTL8, resistin, BMI, blood pressure, duration of diabetes, glycosylated hemoglobin (HbA1c), fasting blood glucose (FPG), hypersensitive C-reactive protein (hs-CRP), lipid profile, liver, and kidney function tests were assessed. The relationship between DN with ANGPTL8 and resistin was analyzed in the unadjusted and multiple-adjusted regression models.ResultsSerum levels of ANGPTL8 and resistin were significantly higher in DN compared with T2DM subjects without DN (respectively; P &lt;0.001), especially in non-NAFLD populations. ANGPTL8 and resistin showed positive correlation with hs-CRP (respectively; P&lt;0.01), and negative correlation with estimated GFR (eGFR) (respectively; P=&lt;0.001) but no significant correlation to HOMA-IR(respectively; P&gt;0.05). Analysis showed ANGPTL8 levels were positively associated with resistin but only in T2DM patients with DN(r=0.1867; P&lt;0.05), and this significant correlation disappeared in T2DM patients without DN. After adjusting for confounding factors, both ANGPTL8(OR=2.095, 95%CI 1.253-3.502 P=0.005) and resistin (OR=2.499, 95%CI 1.484-4.208 P=0.001) were risk factors for DN. Data in non-NAFLD population increased the relationship between ANGPTL8 (OR=2.713, 95% CI 1.494-4.926 P=0.001), resistin (OR=4.248, 95% CI 2.260-7.987 P&lt;0.001)and DN. The area under the curve (AUC) on receiver operating characteristic (ROC) analysis of the combination of ANGPTL8 and resistin was 0.703, and the specificity was 70.4%. These data were also increased in non-NAFLD population, as the AUC (95%CI) was 0.756, and the specificity was 91.2%.ConclusionThis study highlights a close association between ANGPTL8, resistin and DN, especially in non-NAFLD populations. These results suggest that ANGPTL-8 and resistin may be risk predictors of DN.

Abstract Obesity and diabetes prevalence are increasing worldwide. We aimed by this work to detect the possible association of osteoprotegerin (OPG) gene expression with visceral adiposity indices and cardiometabolic risk factors among obese patients. This is research enrolled 150 controls and 150 obese cases subdivided into two subgroups non-diabetic (n = 70) and 80 patients with type 2 diabetes mellitus (T2DM). Circulating OPG expression levels were determined by RT-PCR. Serum OPG concentrations were assessed by ELISA.Our results explored that OPG serum levels were higher in the control group compared to obese women and obese diabetics had higher serum levels of OPG in comparison to obese non-diabetic patients. In obese group, regarding expression levels of OPG were higher than controls in diabetic obese patients, the blood expression levels of OPG were higher than non-diabetics patients. We found positive correlations between parameters of MetS and obesity indices, among them, the highest positive correlation found between VAI. After adjustment of the traditional risk factors, stepwise linear regression analysis test revealed that, OPG expression levels were independently correlated with HbA1c, HDL-cholesterol, and WHR. ROC analysis demonstrated that cutoff values of OPG expression levels and serum levels were 2.226 and 7.5; the AUC were 0.833 (95% CI = 0.821–0.946) and 0.981, respectively. Additionally, the sensitivities and the specificities of OPG expression were (90% and 86.2%), and OPG serum levels (98% and %94), respectively.OPG mRNA and serum levels are useful diagnostic biomarkers discriminate metabolic risk among obesity with or without T2DM.

Purpose The epigallocatechin gallate (EGCG) effect in diabetes has been investigated in animal studies, but results of clinical trials are inconsistent. Thus, this study aims to evaluate the effects of EGCG supplementation in patients with type 2 diabetes mellitus (T2DM). Design/methodology/approach A total of 50 patients with T2DM were recruited in a double-blind, randomized, placebo-controlled trial. The eligible participants were randomly allocated to EGCG (n = 25) and placebo (n = 25) groups. The EGCG group received two capsules of EGCG (each capsule contained 150 mg; Shari Made®, Iran) and placebo group was administered two capsules of placebo (starch) for eight weeks. A three-day 24-h dietary recall and anthropometric and laboratory measurements were carried out at the beginning and the end of the study. Findings At the end of the trial, weight and body mass index (BMI) were decreased significantly in both groups, but the reduction was not statistically significant between the two groups. Fasting blood sugar decreased significantly in EGCG group. No significant between-group and within-group differences were found in insulin, homeostatic model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index values. The high-sensitive C-reactive protein (hs-CRP) was significantly reduced in the EGCG group (4.13 ± 0.48-3.93 ± 0.50, p = 0.003) compared to baseline. Originality/value This study showed that consuming 300 mg/day of EGCG for eight weeks in patients with T2DM caused a significant decrease in fasting blood glucose, body weight, BMI and hs-CRP compared to baseline. Therefore, the EGCG supplementation may improve glycemic control, anthropometric and inflammation status in T2DM.

The aim of our study was to evaluate the effects of vitamin D supplementation on circulating levels of magnesium and selenium in patients with type 2 diabetes mellitus (T2DM). A total of 126 adult Saudi patients (55 men and 71 women, mean age 53.6 ± 10.7 years) with controlled T2DM were randomly recruited for the study. All subjects were given vitamin D3 tablets (2000 IU/day) for six months. Follow-up mean concentrations of serum 25-hydroxyvitamin D [25-(OH) vitamin D] significantly increased in both men (34.1 ± 12.4 to 57.8 ± 17.0 nmol/L) and women (35.7 ± 13.5 to 60.1 ± 18.5 nmol/L, p < 0.001), while levels of parathyroid hormone (PTH) decreased significantly in both men (1.6 ± 0.17 to 0.96 ± 0.10 pmol/L, p = 0.003) and women (1.6 ± 0.17 to 1.0 ± 0.14 pmol/L, p = 0.02). In addition, there was a significant increase in serum levels of selenium and magnesium in men and women (p-values < 0.001 and 0.04, respectively) after follow-up. In women, a significant correlation was observed between delta change (variables at six months-variable at baseline) of serum magnesium versus high-density lipoprotein (HDL)-cholesterol (r = 0.36, p = 0.006) and fasting glucose (r = - 0.33, p = 0.01). In men, there was a significant correlation between serum selenium and triglycerides (r = 0.32, p = 0.04). Vitamin D supplementation improves serum concentrations of magnesium and selenium in a gender-dependent manner, which in turn could affect several cardiometabolic parameters such as glucose and lipids.
