There is increasing evidence that systemic inflammation and insulin resistance constitute interrelated events that contribute to atherosclerosis. We studied the effect of the association between circulating interleukin 6 (IL-6) levels, one of the major mediators of inflammation, and C-reactive protein on insulin resistance and blood pressure in 228 healthy volunteers. The plasma IL-6 concentration was significantly and similarly associated with systolic (SBP) and diastolic (DBP) blood pressure, fasting insulin, and the fasting insulin resistance index (FIRI) in all subjects. When smokers were excluded from the analysis, plasma IL-6 levels correlated with percent fat mass (r = 0.19; P = 0.02), absolute fat mass (r = 0.17; P = 0.03), SBP, DBP, fasting insulin levels, and FIRI. The latter associations persisted after controlling for body mass index (r = 0.15 and r = 0.19; P = 0.02 and P = 0.0004 for SBP and DBP, respectively; r = 0.24 and r = 0.19, P = 0.004 and P = 0.03, for fasting insulin and FIRI, respectively). Gender and smoking status significantly influenced the results. Although IL-6 levels were significantly associated with fasting insulin and FIRI in men, these significant correlations were not observed in women. Conversely, although IL-6 levels were significantly associated with SBP and DBP in women, these coefficients were not statistically significant in men. All of these associations were lost among smokers and remained significant in nonsmokers. As IL-6 is the major mediator of the acute phase response by hepatocytes and induces the synthesis of C-reactive protein (CRP), we also controlled for the latter. Serum CRP levels correlated significantly with IL-6 in all the subjects, but mainly in nonsmokers and men. Of note was that this significant relationship was lost among smokers. CRP was associated with fasting insulin (r = 0.28; P < 0.0001) and FIRI (r = 0.25; P < 0.0001), but not with SBP or DBP (P = NS), in all subjects. Unlike IL-6, the associations between CRP and these parameters were similar in men and women and in smokers and nonsmokers. For insulin and FIRI they were stronger in women and in nonsmokers. CPR significantly correlated with the WHR only in men (r = 0.22; P = 0.01). Using multiple linear regression in a stepwise manner to predict circulating IL-6 levels, smoking status (P = 0.0059) and FIRI (P = 0.03), but not fat mass or SBP, independently contributed to 11% of its variance in men. When CRP was introduced into the model, the latter (P < 0.0001) and smoking status (P = 0.02), but not FIRI, fat mass, or SBP, contributed to 33% of the variance in IL-6 levels. In women, only SBP (P = 0.04) contributed to 5% of its variance. When CRP was introduced into the model, again only SBP (P = 0.01) contributed to 10% of the variance in IL-6 levels. In 25 of these subjects, insulin sensitivity was determined using the frequently sampled iv glucose tolerance test with minimal model analysis, and circulating IL-6 levels were strongly associated with the insulin sensitivity index (r = −0.65; P < 0.0001). Again, this relationship was even stronger in men (r =− 0.75; P < 0.001) and was not significant in women (r = −0.26; P = NS). In all of these subjects, only insulin sensitivity (P = 0.0037), not fat mass, contributed to 21% of the variance of IL-6 levels in a multiple linear regression analysis. In summary, circulating IL-6 levels, by inducing either hypertension in women or insulin resistance in men, constitute a significant proatherogenic cytokine. The mechanisms of these associations should be further investigated.

Biliopancreatic Diversion Surgery

Introduction: Omentin-1 might play a role in the pathogenesis of insulin resistance and obesity. The aim of the present study was to evaluate the influence of weight loss after biliopancreatic diversion on serum omentin-1 concentrations. Material and Methods A Caucasian population of 24 morbid obese patients was analyzed before and after 12 months of a biliopancreatic diversion surgery. Biochemical and anthropometric evaluation were realized at basal visit and at 12 months. Body weight, fat mass, waist circumferences, blood pressure, fasting blood glucose, fasting insulin, insulin resistance (HOMA-IR), lipid concentrations and omentin-1 were measured. Results: After bariatric surgery and in both gender groups (males vs. females); BMI, weight, fat mass, waist circumference, blood pressure, glucose , total cholesterol, LDL cholesterol, triglycerides, HOMA-IR and fasting insulin decreased in a statistical manner from basal values. Omentin-1 levels increased after bariatric surgery and in both gender the improvement was similar (males vs. females); (delta: –87.1 ± 19.0 ng/dL; p = 0.02 vs. –93.8 ± 28.1 ng/dL; p = 0.03). In the multiple regression analysis adjusted by age and sex; BMI kg/m2 (Beta –0.32: 95% CI –3.98 to –0.12) and insulin UI/L (Beta –0.41: 95% CI –8.38 to –0.16) remained in the model with basal omentin-1 levels as dependent variable. The regression model with post-surgery omentin-1 levels as dependent variable showed as independent variables BMI kg/m2 (Beta –0.13: 95% CI –7.69 to –0.09) and insulin UI/L (Beta –0.24: 95% CI –5.69 to –0.08), too. Conclusion: This study showed a significant increase in omentin-1 levels after weight loss secondary biliopancreatic diversion surgery. A weak negative correlation with BMI and basal insulin levels was detected.

<b>Objective</b> Whereas insulin resistance is expressed as reduced glucose uptake in peripheral tissues, the relationship between insulin resistance and brain glucose metabolism remains controversial. Our aim was to examine the association of insulin resistance and brain glucose uptake (BGU) during a euglycemic hyperinsulinemic clamp in a large sample of subjects across a wide range of age and insulin sensitivity. <p><b>Research Design and Methods</b> [<sup>18</sup>F]-fluorodeoxyglucose positron emission tomography (PET) data from 194 subjects scanned under clamp conditions were compiled from a single-center cohort. BGU was quantified by the fractional uptake rate. We examined the association of age, sex, M value from the clamp, steady-state insulin and free fatty acids levels, C-reactive protein, HbA<sub>1c,</sub> and presence of type 2 diabetes with BGU using Bayesian hierarchical modeling. </p> <p><b>Results</b> Insulin sensitivity, indexed by the M value, was associated negatively with BGU in all brain regions, confirming that in insulin resistant subjects BGU is enhanced during euglycemic hyperinsulinemia. In addition, the presence of type 2 diabetes was associated with a further increase in BGU. On the contrary, age was negatively related to BGU. Steady-state insulin levels, C-reactive protein, free fatty acids, sex, and HbA<sub>1c</sub> were not associated with BGU.</p> <p><b>Conclusions </b>In this large cohort of subjects of either sex across a wide range of age and insulin sensitivity,<b> </b>insulin sensitivity is the best predictor of brain glucose uptake. <b></b></p>

ObjectiveIncreased serum C-reactive protein (CRP), an independent predictor of coronary heart disease, was reported in women with polycystic ovary syndrome (PCOS). It remains unclear whether this finding is due to the association between PCOS and either insulin resistance, obesity, or androgen excess, which are all common features of this condition. The aims of this study were to assess whether increased serum CRP is a specific feature of PCOS and to investigate the mechanisms underlying this association.Design and methodsSerum high-sensitivity CRP (hs-CRP) was measured in 86 hyperandrogenic women (age 21.6±4.2 years, body mass index (BMI) 23.6±3.5 kg/m2), 50 with PCOS and 36 with idiopathic hyperandrogenism (HA). Thirty-five BMI-matched healthy women were also studied as controls. In these subjects, endocrine and metabolic profiles were assessed. In all hyperandrogenic subjects and 14 controls, insulin sensitivity was measured by the glucose clamp technique. Body fat was measured by bioelectrical impedance.ResultsHs-CRP concentrations were higher in PCOS women (3.43±2.01 mg/l) than in HA subjects and healthy women (2.43±1.04, P<0.005; and 2.75±0.86 mg/l, P<0.05 respectively versus PCOS). In multiple regression analyses, increased serum hs-CRP was independently predicted by higher body fat and lower insulin sensitivity. However, in lean women, serum-free testosterone was an additional, negative, predictive variable.ConclusionsPCOS is accompanied by a low-grade chronic inflammation. Body fat appears the main determining factor of this finding, which is only partly explained by insulin resistance. At least in lean women, androgen excess per se seems to play an additional, possibly protective, role in this association.

Rosiglitazone Treatment

Objective: Women with polycystic ovary syndrome (PCOS) exhibit elevated levels of serum C-reactive protein (CRP) and impaired endothelium dysfunction which are directly correlated with insulin resistance. Because rosiglitazone improves insulin sensitivity, we tested whether rosiglitazone treatment ameliorates high-sensitivity (hs)CRP levels and endothelial dysfunction in these patients. Design: Thirty-one women with PCOS were recruited (mean age, 24.7±3.9 (s.e.) years; mean body mass index (BMI), 25.6±3.2 kg/m2). All women were treated with 4mg rosiglitazone daily for 12 months. Methods: Serum levels of testosterone, LH, FSH, sex hormone-binding globulin (SHBG), insulin and hsCRP were measured. The BMI, hirsutism scores and insulin sensitivity indices were calculated before and after treatment. Arterial endothelium and smooth muscle function was measured by examining brachial artery responses to endothelium-dependent and endothelium-independent stimuli before and after treatment. Results: After treatment with rosigitazone there were significant decreases in serum testosterone (91.2±37.5 vs 56.1±21.8 ng/dl; P < 0.01) and fasting insulin concentrations (12.5±7.6 vs 8.75±4.03μU/ml; P = 0.015). Insulin resistance indices were significantly improved after rosiglitazone treatment (P < 0.05). There were no significant changes in BMI, waist circumference, serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, FSH and LH levels. Hirsutism score was decreased significantly after treatment (10.8±1.8 vs 7.6±1.7; P < 0.05). Twenty-four of the women reverted to regular menstrual cycles. Levels of SHBG increased significantly after treatment (28.7±8.7 vs 48.4±11.2 nmol/l; P < 0.01). Serum hsCRP levels were decreased significantly after rosiglitazone treatment (0.25±0.1 vs 0.09±0.02 mg/dl; P = 0.006). There was also significant improvement in endothelium-dependent vascular responses after rosiglitazone treatment (9.9±3.9 vs 16.4±5.1%; P < 0.01). Conclusions: We conclude that rosiglitazone treatment improves insulin sensitivity in women with PCOS. It also decreases androgen production without significant weight gain. More importantly, it has beneficial effects on endothelial dysfunction and low-grade chronic inflammation in normal weight young women with PCOS.
