Limited data suggest that folate levels are higher in patients with type 2 diabetes than in subjects with normal glucose tolerance (NGT). We compared the fasting plasma folate, glucose (FPG), body mass index (BMI), and supplementary vitamin use among male subjects with NGT, those with impaired glucose tolerance (IGT), those with newly diagnosed type 2 diabetes, and those with previously diagnosed type 2 diabetes. Plasma folate of patients with newly diagnosed diabetes and that of patients with previously diagnosed diabetes was significantly higher than that of NGT subjects (p < 0.001). Prevalence of vitamin use was lower in newly diagnosed or previously diagnosed diabetic patients compared with non-diabetic subjects. Self-rated vegetable intake was similar among the four groups. FPG, BMI, triglycerides, and systolic blood pressure correlated with plasma folate levels independently of lifestyle factors studied. These results suggest that plasma folate levels are elevated in male diabetic patients independently of health-conscious behavior that is recommended for diabetic people.

AbstractType 2 diabetes is contemporarily a major social and epidemiological problem and among others is a strong risk factor for cardiovascular diseases. Pentraxin 3, a potential early biomarker of atherosclerosis, is an acute-phase reactant produced by the peripheral tissues where the inflammation takes place. In this study we examined a group of patients with type 2 diabetes with and without cardiovascular complications compared to persons with normal glucose tolerance (patients with cardiovascular complications and healthy volunteers). Plasma pentraxin 3 concentration as well as some basic biochemical blood analysis were performed. Moreover, transcranial and carotid Doppler ultrasound examination as well as transthoracic echocardiography were performed. It turned out that there was an association of plasma pentraxin 3 concentration and carotid atherosclerosis found in the control group of patients with cardiovascular complications but with normal glucose tolerance. In the group of patients with type 2 diabetes and cardiovascular complications we have found an association of plasma pentraxin 3 concentration with diastolic left ventricular dysfunction. Additionally, in the group of patients with type 2 diabetes without cardiovascular disease plasma pentraxin 3 concentration was associated with elevated urinary albumin creatinine ratio. Further studies, on a larger group of patients, are required to confirm these observations.

Aim.To evaluate the differences in insulin resistance (IR) among subjects with normal glucose tolerance (NGT), hyperinsulinemia with NGT (HINS), impaired glucose tolerance (IGT), and newly diagnosed type 2 diabetes mellitus (T2DM).Methods.5 NGT, 25 HINS, 25 IGT, and 25 T2DM subjects participated in this research. The hyperinsulinemic-euglycemic clamp technique (HECT) was performed in all of them to evaluate IR levels. The relative factors influencing IR were evaluated. The simple insulin sensitivity indices were calculated, and the correlation between each index and the M value was analyzed.Results.TheMvalues of NGT, HINS, IGT, and T2DM groups were 11.88 ± 2.93 mg·kg−1·min−1, 6.23 ± 1.73 mg·kg−1·min−1, 6.37 ± 2.12 mg·kg−1·min−1, and 6.19 ± 1.89 mg·kg−1·min−1, respectively.Mvalues in HINS, IGT, and T2DM groups were lower than those in the NGT group (P=0.005); however, the differences among the HINS, IGT, and T2DM groups were not statistically significant (P=0.835). The independent factors influencing theMvalue were waistline and fasting insulin level (FINS). The simple insulin sensitivity indices, especially Matsuda and Gutt index, were significantly associated with theMvalue (P<0.01).Conclusion.IR existed in the HINS, IGT, and T2DM groups, and IR levels were consistent in the three groups. The independent factors influencing IR were waistline and FINS.

Background: Prediabetes is defined as a state of glucose metabolism between normal glucose tolerance and type 2 diabetes. Continuous β-cell failure and death are the reasons for the evolution from normal glucose tolerance to prediabetes and finally type 2 diabetes. Introduction: The necessity of new therapeutic approaches in order to prevent or delay the development of type 2 diabetes is obligatory. Liraglutide, a long-acting GLP-1 receptor agonist, has 97% homology for native GLP-1. Identification of the trophic and antiapoptotic properties of liraglutide in preclinical studies, together with evidence of sustained β-cell function longevity during its administration in type 2 diabetes individuals, indicated its earliest possible administration during this disease, or even before its development, so as to postpone or delay its onset. Methods: Pubmed and Google databases have been thoroughly searched and relevant studies were selected. Results: This paper explores the current evidence of liraglutide administration both in humans and animal models with prediabetes. Also, it investigates the safety profile of liraglutide treatment and its future role to postpone or delay the evolution of type 2 diabetes. Conclusion: Liralgutide remains a valuable tool in our therapeutic armamentarium for individuals who are overweight or obese and have prediabetes. Future well designed studies will give valuable information that will help clinicians to stratify individuals who will derive the most benefit from this agent, achieving targeted therapeutic strategies.

We performed this study to access the changes in glucose tolerance over time in a group of women with polycystic ovary syndrome (PCOS) (n = 71) and control women (n = 23) with regular menstrual cycles and baseline normal glucose tolerance. Mean follow-up was between 2 and 3 yr for both groups (PCOS 2.5 ± 1.7 yr; controls 2.9 ± 2.1 yr). Based on World Health Organization glucose tolerance categories, there was no significant difference in the prevalence of glucose intolerance at follow-up in the PCOS group. In the PCOS group, 25 (37%) had impaired glucose tolerance (IGT) and seven (10%) had type 2 diabetes mellitus at baseline, compared with 30 (45%) and 10 (15%), respectively, at follow-up. There were also no differences within groups (PCOS or control) or between groups (PCOS vs. control) in the oral glucose tolerance test-derived measure of insulin sensitivity, but in the women with PCOS who converted to either IGT or type 2 diabetes mellitus, there was a significant decrease (P &lt; 0.0001). At the follow-up visit, the mean glycohemoglobin level was 6.1 ± 0.9% in women with PCOS vs. 5.3 ± 0.7% in the control women (P &lt; 0.001). Women with PCOS and baseline IGT had a low conversion risk of 6% to type 2 diabetes over approximately 3 yr, or 2% per year. The effect of PCOS, given normal glucose tolerance (NGT) at baseline, is more pronounced with 16% conversion to IGT per year. Our study supports that women with PCOS (especially with NGT) should be periodically rescreened for diabetes due to worsening glucose intolerance over time, but this interval may be over several years and not annually.

IntroductionLittle is known about the risk of hypertension in patients with the early stage of type 2 diabetes. We investigated the risk of hypertension in participants with newly diagnosed type 2 diabetes and prediabetes.Research design and methodsThis is a retrospective cohort study consisting of 2136 middle-aged participants (1022 with normal fasting glucose/normal glucose tolerance (NFG/NGT), 418 with impaired fasting glucose (IFG), 466 with impaired glucose tolerance (IGT) and 230 with diabetes) and 3426 elderly participants (1762 with NFG/NGT, 599 with IFG, 781 with IGT, and 284 with diabetes). All participants underwent 75 g oral glucose tolerance tests at baseline.ResultsOver a median 59-month follow-up period, 459 middle-aged and 1170 elderly participants developed hypertension. In middle-aged participants, the odds of incident hypertension were significantly higher in those with IFG (OR 1.40; p=0.019), IGT (OR 1.49; p=0.004), and diabetes (OR 1.55; p=0.013) than those with NFG/NGT, which was no longer significant after adjustment for body mass index. Subgroup analysis showed that the risk of hypertension was significantly higher in diabetes than NFG/NGT only in participants without obesity. Conversely, obesity was a risk factor of hypertension only in those with IFG and NFG/NGT. In elderly participants, there was no difference in the risk of hypertension among the NFG/NGT, IFG, IGT and diabetes groups.ConclusionsThe risk of hypertension is modest in participants with newly diagnosed type 2 diabetes and prediabetes. Our findings suggest that the early stages of type 2 diabetes and prediabetes may be a key period for reducing hypertension, given the pronounced risk of hypertension in patients with diabetes reported in previous studies. In terms of reducing the risk for hypertension, obesity treatment might be advantageous in the early stages rather than the advanced stages of impaired glucose metabolism.

We hypothesized that the serum from individuals with type 2 diabetes mellitus (T2DM) and impaired glucose tolerance (IGT) would reduce in vitro capillary-like network formation compared with normal glucose tolerance (NGT) serum and that this would occur along with higher serum concentrations of inflammatory cytokines and lower concentrations of angiogenic growth factors. Subjects were sedentary, older (55–65 yr) adults with NGT, IGT, or T2DM ( n = 10/group) matched for body mass index. Human retroviral telomerized endothelial cells (HRVT-ECs) or coronary artery endothelial cells (CECs) were used in a capillary-like network formation assay using endothelial basal medium supplemented with 7.5% serum. Quantification of HRVT-EC network length indicated that serum from the T2DM group resulted in 32 and 35% lower network formation than when using serum from the NGT and IGT groups, respectively ( P < 0.05). Serum from T2DM subjects resulted in CEC network formation that was 11 and 8% lower than when using serum from NGT and IGT subjects, respectively ( P < 0.05). Analysis of serum cytokines indicated that IL-6 was 41% and 49% higher in the IGT and T2DM groups, respectively, compared with the NGT group ( P < 0.05) and there was a trend for higher soluble interleukin-6 receptor (sIL-6R; P = 0.06) and IL-8 ( P = 0.08) in the T2DM serum compared with NGT. The use of recombinant IL-6 and sIL-6R at concentrations detected in the T2DM serum also reduced capillary network formation compared with NGT concentrations ( P < 0.05). These results suggest that IL-6 and sIL-6R present in the serum of T2DM individuals impair in vitro endothelial cell function across different cell lines. Our findings may have implications for the microvascular complications associated with T2DM. NEW & NOTEWORTHY Higher concentrations of serum factors, specifically Interleukin-6 and its soluble receptor found in individuals with type 2 diabetes (T2DM) appear to impair endothelial cell capillary-like network formation compared with those present in serum from individuals with impaired glucose tolerance and normal glucose tolerance. This may have implications for the vascular complications associated with T2DM.
