Markers Of Inflammation

OBJECTIVE: The syndrome of polycystic ovaries (PCOS) is a known risk factor for type 2 diabetes. It is not known, however, whether the increase in diabetes risk is related to endocrine abnormalities associated with PCOS such as hyperandrogenemia, or whether it is a consequence of the anthropometric or metabolic alterations frequently observed in PCOS women. DESIGN: Since markers of inflammation are supposed to predict type 2 diabetes, interleukin-6 (IL-6) and C-reactive protein (CRP) in combination with parameters of obesity, insulin resistance and hyperandrogenism were determined in 57 PCOS women and in 20 age-matched healthy controls. In addition, the C-174G IL-6 promoter polymorphism was analyzed as a determinant in influencing IL-6, obesity, and androgen levels in women. RESULTS: Neither CRP nor IL-6 were significantly elevated in lean or obese PCOS women compared with age-matched lean or obese controls. In PCOS patients, variables of body composition (body mass index (BMI), waist to hip ratio, dual-energy X-ray-absorptiometry fat mass) and of insulin resistance were correlated with IL-6 or CRP, while parameters of hyperandogenism were not. Multivariate linear regression analysis revealed that obesity is the dominant force, thus explaining 18% and 24% of the IL-6 or CRP levels, respectively, in PCOS women. No association of IL-6 or BMI to a certain genotype at C-174G could be demonstrated in 50 PCOS patients. The heterozygous GC genotype, however, was associated with lower androstendione levels. Metformin treatment of 9 obese, insulin-resistant PCOS patients over a period of 6 months caused a significant decrease in body weight, body fat mass and total testosterone, but showed no significant decline in IL-6 or CRP concentrations. CONCLUSIONS: In PCOS women, plasma levels of IL-6 and CRP were not increased when compared with age- and BMI-matched controls. BMI was, however, the parameter most strongly related to IL-6 and CRP in PCOS; thus PCOS-related endocrine abnormalities do not appear to activate inflammatory parameters thereby enhancing the risk of diabetes. In PCOS, the type 2 diabetes risk may, therefore, be confined to those with obesity and/or metabolic alterations rather than affecting all women suffering from the syndrome.

Identifying factors that may impact vildagliptin’s efficacy could contribute to individualized treatment for patients with type 2 diabetes. In the current study, we aimed to assess the correlation between patient baseline triglyceride (TG) and efficacy of vildagliptin in Chinese patients with type 2 diabetes in a post hoc analysis of the VISION study. TG-based subgroup analysis was performed to evaluate baseline TG’s impact on the decrease of glycated hemoglobin (HbA1c) in patients receiving vildagliptin plus low-dose metformin (VLDM) vs. high-dose metformin (HDM). Additionally, multivariate linear regression was performed to assess the association between baseline TG and HbA1c reduction at weeks 12 and 24 for patients receiving VLDM vs. HDM. For patients receiving VLDM, baseline TG≤2.03 mmol/L was associated with significantly greater HbA1c reduction vs. TG>2.03 mmol/L at week 12, but not at week 24. Additionally, multivariate linear regression analysis revealed a significant independent association and an association short of statistical significance between patient baseline TG and the HbA1c-reducing efficacy of VLDM at weeks 12 (P<0.001) and 24 (P=0.082), respectively, while such association was absent for HDM. Collectively, baseline TG was an independent predictive factor for the efficacy of a dipeptidyl peptidase-IV in treating type 2 diabetes during its initial use.

Abstract Leptino (LR) and insulin resistance (IR) are significant predictors of atherosclerosis, thrombosis, type 2 diabetes. The effect of epicardial obesity (EO) (as a type of visceral obesity) on the formation of LR and IR is studied. Objective To study the effect of EO on the formation of LR and IR among men with arterial hypertension (AH). Materials and methods The study included 130 men 49.5±4.3 years old, with AH of 1–3 degrees and the absence of clinical manifestations of coronary heart disease and atherosclerosis of other localizations, type 2 diabetes with a BMI of 20–35 kg /m2 and abdominal obesity according to WC ≥94 cm. Patients were divided into two groups depending on the thickness of epicardial adipose tissue (EAT), measured behind the free wall of the right ventricle by echocardiography. Group 1 consisted of 60 patients with epicardial obesity (EAT ≥7 mm), group 2 included 70 patients without epicardial obesity (EAT <7 mm). All subjects assessed indicators of LR and IR: measured levels of serum leptin (SL), soluble receptors for leptin (SLR), free leptin index (FLI), calculated as the ratio SL/SLR (as the only currently existing marker LR); IR was estimated by calculating the HOMA-IR index. IR was diagnosed with the generally accepted HOMA-IR index >2.7. Results When comparing LR indices in the studied groups, higher average values of SL, FLI were observed in the group with EO (EAT ≥7 mm) than in the group without EO (EAT <7 mm): (SL = 32.16 ng/ml (26.7; 37.62) versus SL = 14.92 ng/ml (11.62; 18.22), p=0.01, respectively); (FLI = 1.67 (0.47; 2.87) versus FLI = 0.37 (0.28; 0.46), p=0.01, respectively). Also in the EO group, higher indices of the HOMA-IR index were observed compared with the group without EO: (2.16 (1.62; 2.66) versus 1.35 (1.06; 1.64), p=0,01, respectively). When conducting the correlation analysis between FLI (as a marker of LR) and various obesity indicators (BMI, WC, EO) in the studied groups, a significant positive correlation relationship between FLI and EO was found in both the first and second groups (r=0.67, p=0.01; r=0.62, p=0.01, respectively). The IR index HOMA-IR also significantly positively correlated with EO in the group with a EAT ≥7 mm (r=0.68, p=0.01). BMI and WC did not correlate with FLI, IR in both groups 1 and 2 (p>0.05). In the EO group, 11 patients had IR with a HOMA-IR index >2.7. Using the linear regression analysis, the regression equation was obtained and the value of EO was calculated, from which the IR with HOMA-IR >2.7 started to be determined. This figure was 9.5 mm. Conclusions EO (EAT ≥7 mm) is a significant predictor of LR and IR, unlike the generally accepted criteria for obesity (BMI, WC). A EAT ≥9.5 mm can be a significant predictor of the development of type 2 diabetes, so these patients need additional examinations.

Abstract Objective: The Finnish Diabetes Risk Score (FINDRISC) questionnaire is a practical screening tool to estimate the diabetes risk and the probability of asymptomatic type 2 diabetes. In this study we evaluated the usefulness of the FINDRISC to predict insulin resistance in a population at increased diabetes risk. Design: Data of 771 and 526 participants in a cross-sectional survey (1996) and a cohort study (1997–2000), respectively, were used for the analysis. Data on the FINDRISC and oral glucose tolerance test parameters were available from each participant. The predictive value of the FINDRISC was cross-sectionally evaluated using the area under the curve-receiver operating characteristics method and by correlation analyses. A validation of the cross-sectional results was performed on the prospective data from the cohort study. Results: The FINDRISC was significantly correlated with markers of insulin resistance. The receiver operating characteristics-area under the curve for the prediction of a homeostasis model assessment insulin resistance index of more than five was 0.78 in the cross-sectional survey and 0.74 at baseline of the cohort study. Moreover, the FINDRISC at baseline was significantly associated with disease evolution (P &lt; 0.01), which was defined as the change of glucose tolerance during the 3 yr follow-up. Conclusions: The results indicate that the FINDRISC can be applied to detect insulin resistance in a population at high risk for type 2 diabetes and predict future impairment of glucose tolerance.

Recent evidence shows divergence between the concentrations of extracellular 70 kDa heat shock protein [eHSP70] and its intracellular concentrations [iHSP70] in people with type 2 diabetes (T2DM). A vital aspect regarding HSP70 physiology is its versatility to induce antagonistic actions, depending on the location of the protein. For example, iHSP70 exerts a powerful anti-inflammatory effect, while eHSP70 activates proinflammatory pathways. Increased eHSP70 is associated with inflammatory and oxidative stress conditions, whereas decreased iHSP70 levels are related to insulin resistance in skeletal muscle. Serum eHSP70 concentrations are positively correlated with markers of inflammation, such as C-reactive protein, monocyte count, and TNF-α, while strategies to enhance iHSP70 (e.g., heat treatment, chemical HSP70 inducers or coinducers, and physical exercise) are capable of reducing the inflammatory profile and the insulin resistance state. Here, we present recent findings suggesting that imbalances in the HSP70 status, described by the [eHSP70]/[iHSP70] ratio, may be determinant to trigger a chronic proinflammatory state that leads to insulin resistance and T2DM development. This led us to hypothesize that changes in this ratio value could be used as a biomarker for the management of the inflammatory response in insulin resistance and diabetes.

Dipeptidyl Peptidase 4

Context: The significance of associations between prediabetes, type 2 diabetes, and dipeptidyl peptidase-4 (DPP4) activity in a Chinese population is not clear. Objective: The objective of the study was to determine whether DPP4 activity and active glucagon-like peptide-1 (GLP-1) were predictive of the onset of prediabetes and type 2 diabetes. Design, Setting, and Patients: This was a 4-year follow-up study conducted in Sichuan, China. A total of 474 Chinese women and men aged 18–70 years were studied. Main Outcome Measures: All subjects were divided into 3 groups (normal glucose tolerance, prediabetes, and type 2 diabetes) on the basis of their glucose metabolism status after 4 years. The DPP4 activity, active GLP-1, and glucagon were measured at baseline and 4 years later. Results: The baseline DPP4 activity was significantly higher in subjects who had progressed to prediabetes or type 2 diabetes compared with subjects who remained normoglycemic (P &lt; .01). In a multiple linear regression analysis, baseline DPP4 activity and active GLP-1 were independent predictors of an increase in insulin resistance over a 4-year period (P &lt; .05). Cox proportional hazards models revealed that DPP4 activity independently predicted the risk of developing prediabetes [relative risk 2.77 (95% confidence interval 1.38–5.55), P &lt; .01] and type 2 diabetes [5.10 (95% confidence interval 1.48–17.61), P &lt; .05] after adjustment for confounding risk factors. Conclusions: DPP4 activity is an important predictor of the onset of insulin resistance, prediabetes, and type 2 diabetes in apparently healthy Chinese individuals. This finding may have important implications for understanding the etiology of diabetes.

BackgroundLipoprotein Insulin Resistance Index (LP-IR) and Diabetes Risk Index are novel spectroscopic multimarkers of insulin resistance and type 2 diabetes risk. As the Studies of a Targeted Risk Reduction Intervention through Defined Exercise (STRRIDE) randomized trials have previously demonstrated the ability of exercise training to improve traditional markers of insulin action, the aim of this study was to examine the effects of exercise amount, intensity, and mode on LP-IR and the Diabetes Risk Index.MethodsA total of 503 adults with dyslipidemia [STRRIDE I (n = 194), STRRIDE AT/RT (n = 139)] or prediabetes [STRRIDE-PD (n = 170)] were randomized to control or one of 10 exercise interventions, ranging from doses of 8–23 kcal/kg/week; intensities of 50–75% V̇O2peak; and durations of 6–8 months. Two groups included resistance training and one included dietary intervention (7% weight loss goal). Fasting plasma samples were obtained at baseline and 16–24 h after the final exercise bout. LP-IR, the Diabetes Risk Index, and concentrations of the branched chain amino acids valine and leucine were determined using nuclear magnetic resonance spectroscopy. LP-IR and the Diabetes Risk Index scores range from 0–100 and 1–100, respectively (greater scores indicate greater risk). Paired t-tests determined significance within groups (p &lt; 0.05).ResultsAfter training, six exercise groups significantly improved LP-IR (ranging from −4.4 ± 8.2 to −12.4 ± 14.1), and four exercise groups significantly improved the Diabetes Risk Index (ranging from −2.8 ± 8.2 to −8.3 ± 10.4). The most beneficial interventions for both LP-IR and the Diabetes Risk Index were low amount/moderate intensity aerobic, aerobic plus resistance, and aerobic plus diet.SummaryMultiple exercise interventions improved LP-IR and the Diabetes Risk Index. In those with dyslipidemia, adding resistance to aerobic training elicited a synergistic effect on insulin resistance and type 2 diabetes risk. In individuals with prediabetes, combining a dietary intervention and weight loss with aerobic training resulted in the most robust type 2 diabetes risk improvement.

Abstract. Background: Osteoprotegerin plays a role in the development of several bone diseases. In addition, osteoprotegerin may contribute to the development of vascular disease. Little is known about the association between serum osteoprotegerin levels and the presence or severity of peripheral arterial disease (PAD). The aim of this study was to examine the association between serum osteoprotegerin levels and both the presence as well as the severity of lower extremity arterial disease in patients with type 2 diabetes (T2DM). Patients and methods: The study included 165 consecutive patients with T2DM (57 % males, mean age 65.0 ± 0.7 years). PAD was diagnosed by measurement of the toe-brachial index (TBI). Serum osteoprotegerin was measured using ELISA. Results: The mean osteoprotegerin level was significantly higher in patients with PAD in comparison to patients without PAD (18.2 ± 1.0 vs. 13.1 ± 2.0 pmol/L, p = 0.014). Significant univariate correlations between TBI and osteoprotegerin level (r = –0.308; p < 0.001), age, body mass index, and HDL cholesterol were observed. In the multivariate linear regression analysis, serum osteoprotegerin (β = –0.005; p = 0.020), higher age, and male gender were significant predictors of TBI. When 25(OH) vitamin D was introduced into the mentioned model, OPG was no longer a significant predictor of TBI and was replaced in the model with vitamin D (β = 0.009, p = 0.001). This finding suggests a role of OPG as a mediator of the effects of 25(OH) vitamin D. Conclusions: Serum osteoprotegerin level is significantly associated with both the presence and severity of PAD in patients with T2D. Osteoprotegerin might be a biomarker for the presence of atherosclerotic disease in patients with T2DM.
