Statin therapy improves lipid profiles and reduces vascular inflammation, but its effects on central arterial stiffness in type 2 diabetes are unclear. The aim of this study was to determine whether statin therapy reduces central arterial stiffness, in a dose-dependent manner, in male patients with type 2 diabetes. Fifty-one patients ceased statin therapy for 6 weeks, followed by randomisation to either 10 or 80 mg of atorvastatin. At randomization, 3 and 12 months, central arterial stiffness was measured via carotid-femoral pulse wave velocity (PWV), along with serum markers of vascular inflammation including high-sensitivity c-reactive protein (hsCRP) and osteoprotegerin (OPG). PWV decreased from 10.37 ± 1.30 to 9.68 ± 1.19 m/sec (p<0.01from baseline) at 3 months and 9.10 ± 1.17 m/sec (p<0.001from baseline) at 12 months. hsCRP and OPG decreased significantly at 3 and 12 months. Reductions in PWV did not differ significantly between the groups. Baseline PWV and OPG values correlated strongly (r=0.48,p<0.01), as did their response to atorvastatin over 12 months (r=0.36delta-OPG and delta-PWV,p<0.01). Atorvastatin therapy appeared to reduce central arterial stiffness in male type 2 diabetes, with no dose-dependent effect observed. The correlation observed between reductions in PWV and OPG suggests that atorvastatin reduces PWV via direct anti-inflammatory effects on the vasculature.

G-protein coupled receptor 119 (GPR119) has emerged as a promising new target for the treatment of type 2 diabetes mellitus. The expression of GPR119 on the pancreatic B cells and intestinal L cells provides a unique opportunity for a single drug to promote insulin and GLP-1 secretion. In this study, we identified a novel small molecule GPR119 agonist, HD0471953, from our large library of synthetic compounds based on its ability to anti-hyperglycemic effects on T2DM murine models. We have tested the acute efficacy of HD0471953 by the oral glucose tolerance test (OGTT) with normal C57BL/6J mice. Then, chronic administrations of HD0471953 were performed to evaluate the efficacy on various diabetic rodent models. Single administration of HD0471953 showed improved glycemic control with a dose-dependent manner in OGTT with normal mice, and the insulin and GLP-1 were also increased. To identify chronic efficacy, we have observed a decline of blood glucose and fasting insulin in a dose-dependent manner of 10, 20, and 50 mpk indb/dbmice. The results suggest that HD0471953 may be a potentially promising anti-hyperglycemic agent for the treatment of patients with type 2 diabetes mellitus.

Background: Insulin resistance (IR) and inflammation are closely related to each other and share common pathophysiological and metabolic mechanisms. We aimed to investigate the combined effect of IR and inflammation on comorbidities of type 2 diabetes mellitus (T2DM). Methods: A total 3,758 patients with T2DM were recruited through Huh’s Diabetes Center from January 2003 to June 2009. Insulin sensitivity was measured by a rate constant for plasma glucose disappearance (Kitt , %/min) using short insulin tolerance test. High sensitivity C-reactive protein (hs-CRP) was used as a surrogate for inflammation.Results: Patients with the lowest tertile of Kitt (IR group) showed worse cardio-metabolic parameters while those with the highest tertile of hs-CRP levels had worse cardio-metabolic parameters. The prevalence of metabolic syndrome, fatty liver, albuminuria, and carotid atherosclerosis decreased with Kitt tertile, but increased with hs-CRP tertile. In multiple regression analysis, both Kitt and hs-CRP were independent risk factors for comorbidities of T2DM. In addition, they showed synergistic effects on these comorbidities. Conclusion: Both IR and inflammation were significantly associated with comorbidities of T2DM in a dose dependent manner. In addition, the coexistence of IR and inflammation may synergistically contribute to increased comorbidities of T2DM.

Abstract We have identified a gene encoding transcription factor activating enhancer binding protein-2β (TFAP2B) as a candidate for conferring susceptibility to type 2 diabetes. Although we have also found that TFAP2B was preferentially expressed in adipose cells in a differentiation-dependent manner, the mechanisms by which the gene and gene polymorphisms contribute to conferring susceptibility to the disease have not yet been elucidated. The aim of this study was to evaluate the impact of the polymorphisms within the TFAP2B gene on conferring susceptibility to type 2 diabetes. We identified that a 300-bp DNA fragment in intron 1 of TFAP2B had significant enhancer activity, and the variations of this region affected this enhancer activity in differentiated adipocytes. In an experiment using adenovirus vectors encoding TFAP2B, the expression of TNF-α gene was shown to be elevated in the TFAP2B overexpressing cells compared with those in control cells. Furthermore, we demonstrated that the expression of TFAP2B was increased in the adipose tissues of subjects with the disease-susceptibility allele, and the plasma levels of TNF-α and high sensitivity C-reactive peptide were significantly elevated in the patients with the disease-susceptibility allele. These results suggest that TFAP2B may contribute to the pathogenesis of type 2 diabetes through regulation of adipocytokine gene expression, and that TFAP2B may be a promising target for treatment or prevention of this disease.

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.

Background: Type 2 diabetes mellitus is a chronic disease characterized by relative or absolute deficiency of insulin, resulting in glucose intolerance.Objectives: The present study was planned to see the associations of serum uric acid with positive Rheumatoid factor in type 2 male diabetes mellitus patients. Methodology: This case control study was carried out at the department of Biochemistry at Ibrahim Medical College, Dhaka, Bangladesh. The duration of the study was from June 2015 to June 2016 for a period of one year. In this present study, male patients with type 2 diabetes mellitus were taken as case group and age and sex matched healthy male were taken as control group. Rheumatoid factor was measured from the blood of all case and control group respondents. Others blood para meters were also measured for the correlation with the diabetes mellitus patients.Results: In this present study, 110 male patients presented with type 2 diabetes mellitus were recruited as case and age and sex matched healthy male were recruited as control. More rheumatoid factor positive in type 2 DM male patients with the uric acid range between 6.5 to 9.5 mg/dL. The number of patients was 5 out of total 9 rheumatoid factor positive cases. In this study serum uric acid was significantly correlated with rheumatoid factor in type 2 male diabetic patients. Rheumatoid factor positive cases were taking insulin among 9 and it was statistically significantly associated (p<0.001). Conclusion: In this study serum uric acid is significantly associated with positive rheumatoid factor in type 2 male diabetic patients.Journal of Current and Advance Medical Research 2017;4(2):58-62
