rome and Metabolic-Syndrome

PCOS is the main cause of infertility due to metabolic, hormonal and ovarian dysfunctions. Women affected by PCOS often suffer of insulin resistance and of a compensatory hyperinsulinemia. These conditions put the patients at risk of developing several metabolic disorders. Both myo-inositol (MI) and D-chiro inositol (DCI) glycans administration has been reported to exert beneficial effects at metabolic, hormonal and ovarian level. Beside these common features, MI and DCI are indeed different molecules: they belong to two different signal cascades and regulate different biological processes.. In this study, we aim to verify whether the two molecules have a synergistic action by acting on their specific cellular pathways. The effectiveness in reducing the risk of metabolic syndrome as well as in enhancing the ovarian functions of a combined therapy with MI and DCI was compared to a mono therapy in a randomized controlled trial.. Fifty overweight women with PCOS were enrolled and divided in two groups to receive MI and DCL (MI+DCI group) or MI alone (MI group) for a period of six months. Baseline measurements were repeated at three months (T1) and at the end of the treatment (T2).. At the end of the treatment, both MI and MI+DCI groups showed an improvement of the metabolic parameters and no significant differences were found. As expected, the combined supplementation with MI and DCI resulted to be more effective, compared to the MI group, after three months of treatment.. The combined administration of MI and DCI in physiological plasma ratio (40:1) should be considered as the first line approach in PCOS overweight patients, being able to reduce the metabolic and clinical alteration of PCOS and, therefore, reduce the risk of metabolic syndrome.

We previously demonstrated that children with Down syndrome (DS) exhibited a greater risk of steatosis than the general pediatric population. This trend was independent of obese phenotype, thus suggesting a role of genetic predisposition. Therefore, we investigated the prevalence of non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS) in function of genetic susceptibility and adipocytokine levels in children with DS.. A total of 84 Caucasian children with DS (age range 5-17 years), were included in this study. For all children, we collected data on anthropometric and biochemical parameters, and liver ultrasound (US). We also measured adipocytokines circulating levels and specific polymorphisms closed to NAFLD. We found a prevalence of 64.3% of liver steatosis at US, with a severe steatosis of about 4% in children with DS. The presence of steatosis in children with DS was associated with the presence of patatin-like phospholipase domain-containing 3 (PNPLA3) rs738409 variant, which also correlated with interleukin (IL)-6 levels. Moreover, we found that the 52.4% had a waist circumference > 90th percentile, 21.4% were hypertensive, 7.14% had hyperglycemia, 9.5% had hypertriglyceridemia, and 17.9% showed high-density lipoprotein cholesterol ≤ 40 mg/dl. Finally, the IL-6 and adiponectin levels correlated with steatosis, and several adipocytokines correlated with single MetS traits in children with DS.. The present study explores for the first time potential pathomechanisms connecting pediatric NAFLD and MetS in DS. We found that the PNPLA3 variant is associated with steatosis, but not with MetS, in children with DS.

Nonalcoholic fatty liver disease (NAFLD) has a high prevalence in the general population. Brachial artery flow-mediated dilation (FMD) is a surrogated marker of early atherosclerosis. Few data investigating the relation between FMD, NAFLD, and cardiovascular (CV) risk are available. We recruited 367 consecutive outpatients with cardiometabolic risk factors who underwent ultrasound scanning for liver steatosis and FMD. Mean age was 54.2 ± 12.2 years, and 37% were women. NAFLD was present in 281 patients (77%). Median FMD was 5.1%. FMD was significantly reduced in patients with NAFLD (p <0.001), diabetes (p = 0.001), history of coronary heart disease (p = 0.034), and metabolic syndrome (p = 0.050) and in those taking antihypertensive drugs (p = 0.022). Women disclosed greater FMD than males (p = 0.033). Moreover, FMD inversely correlated with age (Spearman rank correlation test [Rs], -0.171; p = 0.001), waist circumference (Rs, -0.127; p = 0.016), fasting blood glucose (Rs, -0.204; p <0.001), and gamma-glutamyl transpeptidase (Rs, -0.064; p = 0.234). At multivariate regression analysis, fasting blood glucose (β, -0.148; p = 0.008), age (β, -0.158; p = 0.005), and the presence of NAFLD (β, -0.132; p = 0.016) inversely correlated with FMD, whereas female gender predicted a better FMD (β, 0.125; p = 0.022). FMD and Framingham Risk Score (FRS) were inversely correlated (Rs, -0.183; p <0.001). After dividing patients into low (FRS <10; FMD, 5.5% [3.1% to 8.9%]), intermediate (FRS 10 to 20; FMD, 4.9% [2.7% to 7.5%]), and high (FRS >20; FMD, 3.3% [1.7% to 4.5%]) risk, FMD significantly decreased across risk classes of FRS (p = 0.003). At multivariate regression analysis, both FRS (β, -0.129; p = 0.016) and NAFLD (β, -0.218; p <0.001) were variables independently associated with FMD. In conclusion, the presence of NAFLD and FRS inversely correlated with FMD.

To date, the relationship among adiposity, insulin resistance, and cardiovascular risk factors at the onset of overweight or obesity has been unexplored.. To assess whether insulin resistance and metabolic abnormalities are detectable at the onset of obesity and to unravel the interplay among adiposity, insulin resistance, and other such abnormalities.. The Origin of Cardiovascular Risk in Overweight Preschool Children cohort study aimed to evaluate at the onset of obesity in preschool children the prevalence of metabolic abnormalities, including hypertension, dyslipidemia, impaired carbohydrate metabolism, and nonalcoholic fatty liver disease. Between July 1, 2011, and July 30, 2012, in the Rome municipality, 13 family pediatricians enrolled healthy children (age range, 2.0-5.8 years) in the study during their routine practice of growth monitoring. Clinical medical records of 5729 children were reviewed; 597 children manifested new-onset overweight or obesity as their body mass index changed from normal weight to overweight or obesity in the previous 12 months according to the International Obesity Task Force classification. Of them, 219 were studied.. Patients with new-onset overweight or obesity underwent clinical laboratory testing, including oral glucose tolerance test, and ultrasonographic investigations of fatty liver and intimal medial thickness of the common carotid arteries, subcutaneous adipose tissue, and visceral adipose tissue. The homeostatic assessment model algorithm-insulin resistance was calculated.. Among the entire population (n = 5729), overweight increased from 7.0% at 2.0 years to 16.9% at 5.8 years, with corresponding figures of 1.1% to 2.9% for obesity. In total, 597 overweight or obese children (10.4%) were identified, and 219 of them (36.7%) were studied. Among the latter, 86 patients (39.3%) had at least 1 metabolic abnormality. Hypertension was diagnosed in 29 patients (13.2%), dyslipidemia in 55 patients (25.1%), impaired fasting glucose level in 7 patients (3.2%), and glucose intolerance in 6 patients (2.7%). Nonalcoholic fatty liver disease was diagnosed in 68 patients (31.1%).. Cardiometabolic risk factors, including fatty liver, are detectable in preschoolers at the onset of overweight or obesity, despite short-term exposure to excess weight and reduced insulin sensitivity. Our findings suggest the need to screen for cardiometabolic abnormalities at an earlier age than is now recommended.

This study aims to investigate prevalence of hypertension and cardiovascular risk factor clustering in children and adolescents attending a lipid clinic as well as the relationship of their hypertensive status with indicators of fat distribution and parental fat distribution and blood pressure (BP). In this cross-sectional primary prevention study, data on indicators of fat distribution (waist, hip, and middle-upper arm circumferences), body mass index (BMI), BP, high-sensitivity C-reactive protein (hsCRP), lipid and glucose profile of 370 children and adolescents (180 M, 190 F, mean age 9.5 years, (range 6-14 years)) were collected. Parents (502, 251 M, 251 F, age range 28-36 years), who gave their informed consent, underwent BMI, fat distribution, and BP measurements. There were 131 (35.4 %) hypercholesterolemic subjects and 72 (19.5 %) hypertensives. Using tests on medians, in comparison with 298 normotensives, the 72 hypertensives had higher levels of insulin (p<0.005) and no differences in cholesterol levels, age, and height. BMI and all the indicators of fat distribution were significantly higher (all p<0.01) in hypertensives than normotensives. BMI and waist circumferences were higher (both p<0.05) in the mothers of hypertensives, but not in the fathers. Hypertensive subjects' BMI was related to mothers' hip and waist circumferences (r=0.28 and 0.21, respectively).. In this study, children's hypertension was a component of the metabolic syndrome, but uric acid and hsCRP levels were not contributive. This hemodynamic and metabolic disorder was related to maternal fat distribution and BMI suggesting an epigenetic etiology.

The metabolic syndrome (MS) is associated with left ventricular hypertrophy (LVH). Previous evidence has shown that LVH is favoured by low levels of atrial natriuretic peptide (ANP), independently from blood pressure (BP), in hypertension. Although levels of natriuretic peptides are known to be lower in obesity, plasma ANP levels have not yet been assessed in MS. We aimed to assess the ANP levels and their relationship with left ventricular mass (LVM) in patients affected by MS.. One hundred and twenty-eight essential hypertensive patients were included in the study: 51 with MS and 77 without MS. Clinical, echocardiographical and biochemical parameters, and levels of both N-terminal (NT)-proANP and alphaANP were assessed.. Hypertensive patients affected by MS had higher LVM and increased frequency of LVH. NT-proANP levels were significantly lower in MS, independent of waist circumference (WC). Log(NT-proANP) levels were significantly inversely related to left ventricular mass index (LVMI) (beta = -0.360, P < 0.001) and LVM/height (beta = -0.370, P < 0.001) in the whole hypertensive population by multiple linear regression analysis. The relationship of log(NT-proANP) with LVM was more enhanced in patients with MS.. The present study demonstrates that levels of NT-proANP are significantly reduced in hypertensive patients affected by MS, and they are significantly inversely related to the increased LVM observed in these patients. Our findings, while supporting previous experimental and clinical evidence of the antihypertrophic role of ANP in hypertension, may help to identify one of the possible mechanisms directly underlying LVH in MS.
