Comparison of different definitions of the metabolic syndrome.

BACKGROUND: The International Diabetes Federation (IDF) published a new definition of the metabolic syndrome (MetS). For this definition we compared frequency, concordance, clinical and laboratory stigmata and carotid atherosclerosis with those of the established definitions by the National Cholesterol Education Program (NCEP) and World Health Organization (WHO). MATERIALS AND METHODS: A total of 1518 subjects (943 men, 575 women) from the Salzburg Atherosclerosis Prevention Program in Subjects at High Individual Risk (SAPHIR), free of clinical atherosclerosis, were included in this study. To estimate insulin sensitivity two methods, i.e. homeostasis model assessment of insulin resistance (HOMA-IR) and the short insulin tolerance test, were employed. Carotid intima media thickness (IMT) and plaque extent were quantified for all subjects using high-resolution ultrasound. RESULTS: Prevalence of the MetS was 18.7% for men and 16.2% for women for the WHO definition, 18.9% and 17.0%, respectively, for the NCEP definition, and 25.8% and 19.5%, respectively, for the IDF definition. Concordance was lower between the definitions of WHO and IDF (< 50%) than between NCEP and IDF (> 67%). Compared to subjects identified by NCEP definition, subjects identified in excess by IDF (3.1-11.7%) showed less insulin resistance and lower IMT and plaque extent indistinguishable from MetS-free subjects. CONCLUSIONS: Our data suggest that the IDF definition includes subjects as MetS sufferers above these detected by NCEP or WHO, who exhibit considerably less insulin resistance and carotid atherosclerosis blurring the distinction between health and disease.

Postprandial lipaemia induces an acute decrease of insulin sensitivity in healthy men independently of plasma NEFA levels.

AIMS/HYPOTHESIS: Typical Western diets cause postprandial lipaemia for 18 h per day. We tested the hypothesis that postprandial lipaemia decreases insulin sensitivity. SUBJECTS, MATERIALS AND METHODS: Employing a randomised crossover design, we administered two types of virtually isocaloric meals to ten healthy volunteers on two separate occasions. The meals (Meals 1 and 2) were both designed to produce a rise in triglycerides, but only Meal 1 generated a rise in NEFA, too. Insulin sensitivity, as quantified by an IVGTT with minimal model analysis, was calculated postabsorptively at 08.00 h and postprandially at 13.00 h, i.e. 3 h after meal ingestion. RESULTS: Triglycerides rose from 0.91+/-0.31 mmol/l postabsorptively to 2.08+/-0.70 mmol/l postprandially with Meal 1 (p=0.005) and from 0.92+/-0.41 to 1.71+/-0.79 mmol/l with Meal 2 (p=0.005). Neither the triglyceride levels at 13.00 h, nor the post-meal AUCs for triglycerides were statistically different between Meal 1 and Meal 2. NEFA rose from 0.44+/-0.17 mmol/l postabsorptively to 0.69+/-0.16 mmol/l postprandially with Meal 1 (p=0.005) and showed no significant change with Meal 2 (0.46+/-0.31 mmol/l postabsorptively vs 0.36+/-0.32 mmol/l postprandially, p=0.09). Both the NEFA level at 13.00 h and the post-meal AUC for NEFA were significantly higher after Meal 1 than Meal 2. Compared with the postabsorptive state, insulin sensitivity decreased postprandially after each of the two meals to a comparable degree (Meal 1: -53%, p=0.02; Meal 2: -45%, p=0.005). CONCLUSIONS/INTERPRETATION: Our study reveals a drop in insulin sensitivity during postprandial lipaemia and strongly suggests that decreased insulin sensitivity is brought about by elevated plasma levels of triglyceride-rich lipoproteins independently of plasma NEFA levels.

Plasma cholesteryl ester transfer protein concentrations predict cardiovascular events in patients with coronary artery disease treated with pravastatin.

OBJECTIVE: The B1B1 variant of the cholesteryl ester transfer protein (CETP) TaqIB polymorphism and high plasma CETP concentrations are associated with favourable angiographic outcomes in pravastatin-treated patients suffering from coronary artery disease (CAD). The purpose of the present study was to test whether CETP TaqIB genotypes and/or plasma CETP concentrations at baseline also predict clinical end-points in patients with CAD. DESIGN: Prospective longitudinal observational study. SETTING: Primary care doctors (n=88) and hospitals (n=7) in Austria. SUBJECTS: A total of 1620 men and women with preexisting CAD were recruited and plasma lipids were determined at study entry. 1389 hypercholesterolaemic patients were included and 1002 patients completed the follow-up. INTERVENTIONS: In all patients treatment with pravastatin was started and patients were followed up for 2 years. MAIN OUTCOME MEASURES: Cardiovascular events. RESULTS: One hundred patients suffered at least one cardiovascular event. We observed significantly more events in patients within the lowest compared with the highest quartile of plasma CETP concentrations (odds ratio 3.20, CI95 1.65-6.23; P=0.001, adjusted for known risk factors of CAD). No significantly different numbers of cardiovascular events were found between CETP TaqIB genotypes. CONCLUSIONS: Plasma CETP concentrations, but not CETP TaqIB genotypes, predict cardiovascular events in patients with CAD treated with pravastatin. Despite higher LDL cholesterol concentrations, high plasma CETP concentrations at baseline are associated with fewer cardiovascular events compared with low plasma CETP concentrations in CAD patients treated with pravastatin.

Human triglyceride-rich lipoproteins impair glucose metabolism and insulin signalling in L6 skeletal muscle cells independently of non-esterified fatty acid levels.

AIMS/HYPOTHESIS: Elevated fasting and postprandial plasma levels of triglyceride-rich lipoproteins (TGRLs), i.e. VLDL/remnants and chylomicrons/remnants, are a characteristic feature of insulin resistance and are considered a consequence of this state. The aim of this study was to investigate whether intact TGRL particles are capable of inducing insulin resistance. METHODS: We studied the effect of highly purified TGRLs on glycogen synthesis, glycogen synthase activity, glucose uptake, insulin signalling and intramyocellular lipid (IMCL) content using fully differentiated L6 skeletal muscle cells. RESULTS: Incubation with TGRLs diminished insulin-stimulated glycogen synthesis, glycogen synthase activity, glucose uptake and insulin-stimulated phosphorylation of Akt and glycogen synthase kinase 3. Insulin-stimulated tyrosine phosphorylation of IRS-1, and IRS-1- and IRS-2-associated phosphatidylinositol 3-kinase (PI3K) activity were not impaired by TGRLs, suggesting that these steps were not involved in the lipoprotein-induced effects on glucose metabolism. The overall observed effects were time- and dose-dependent and paralleled IMCL accumulation. NEFA concentration in the incubation media did not increase in the presence of TGRLs indicating that the effects observed were solely due to intact lipoprotein particles. Moreover, co-incubation of TGRLs with orlistat, a potent active-site inhibitor of various lipases, did not alter TGRL-induced effects, whereas co-incubation with receptor-associated protein (RAP), which inhibits interaction of TGRL particles with members of the LDL receptor family, reversed the TGRL-induced effects on glycogen synthesis and insulin signalling. CONCLUSIONS/INTERPRETATION: Our data suggest that the accumulation of TGRLs in the blood stream of insulin-resistant patients may not only be a consequence of insulin resistance but could also be a cause for it.

Effect of pronounced weight loss on the nontraditional cardiovascular risk marker matrix metalloproteinase-9 in middle-aged morbidly obese women.

OBJECTIVE: Obesity is associated with increased morbidity and mortality from atherosclerotic disease. Nontraditional cardiovascular risk factors such as C-reactive protein (CRP) and interleukin-6 (IL-6) are elevated in obese subjects and weight loss is associated with an attenuation of these risk factors. Matrix metalloproteinase-9 (MMP-9) has been linked to plaque rupture, and is, thus, a candidate marker of future myocardial events. The aim of this study was to determine the influence of weight loss on MMP-9 plasma concentrations. METHODS AND RESULTS: CRP, IL-6 and MMP-9 were analyzed from samples of 45 morbidly obese, middle-aged women before gastric banding and 1 y postsurgical treatment in this prospective study. The body mass index (BMI) of subjects decreased from 42.5+/-4.9 to 32.3+/-5.3 kg/m(2) 1 y after gastric banding. In parallel, both MMP-9 and CRP were reduced by 23 and 41%, respectively. A positive relationship was found between BMI and MMP-9 (r=0.312, P<0.05), and between CRP and IL-6 (r=0.508, P<0.05), whereas no correlation was found between CRP and MMP-9. CONCLUSIONS: We conclude that weight loss is associated with a pronounced decrease in the nontraditional cardiovascular risk markers MMP-9 and CRP, which could indicate future beneficial effects of weight loss on the cardiovascular risk in weight loosing subjects.

Olanzapine impairs glycogen synthesis and insulin signaling in L6 skeletal muscle cells.

Second-generation antipsychotic agents (SGAs) are increasingly replacing first-generation antipsychotic agents due to their superior activity against the negative symptoms of schizophrenia, decreased extrapyramidal symptoms and better tolerability. However, some SGAs are associated with adverse metabolic effects as significant weight gain, lipid disorders and diabetes mellitus. The pathogenesis of SGA-induced disturbances of glucose homeostasis is unclear. In vivo studies suggest a direct influence of SGAs on peripheral insulin resistance. To this end, we analyzed whether olanzapine might alter glycogen synthesis and the insulin-signaling cascade in L6 myotubes. Glycogen content was diminished in a dose- and time-dependent manner. Within the insulin-signaling cascade IRS-1 tyrosine phosphorylation was induced several fold by insulin and was diminished by preincubation with olanzapine. IRS-1-associated PI3K activity was stimulated by insulin three-fold in L6 myotubes. Olanzapine inhibited insulin-stimulated IRS-1-associated PI3K activity in a dose-dependent manner. Protein mass of AKT, GSK-3 and GS was unaltered, whereas phosphorylation of AKT and GSK-3 was diminished, and pGS was increased. Finally, we compared olanzapine with amisulpride, an SGA clinically not associated with the induction of diabetes mellitus. Glycogen content was diminished in olanzapine-preincubated L6 cells, whereas this effect was not observed under the amisulpride conditions. We conclude that olanzapine impairs glycogen synthesis via inhibition of the classical insulin-signaling cascade and that this inhibitory effect may lead to the induction of insulin resistance in olanzapine-treated patients.

Circulating adiponectin reflects severity of liver disease but not insulin sensitivity in liver cirrhosis.

BACKGROUND: The adipocytokine adiponectin has been proposed to play important roles in the regulation of energy homeostasis, insulin sensitivity and shows anti-inflammatory properties. AIM: In this study we investigated the role of circulating adiponectin in different chronic liver diseases, its regulation by systemic anti-tumour necrosis factor (TNF)-alpha treatment and its hepatic metabolism. PATIENTS AND METHODS: Plasma adiponectin levels were determined in 87 patients with liver cirrhosis of different aetiologies, seven patients with alcoholic steatohepatitis undergoing systemic anti-TNF-alpha treatment, in 11 patients with liver cirrhosis receiving transjugular intrahepatic portosystemic shunt implantation and in 21 healthy controls. RESULTS: Adiponectin levels were significantly higher in all subjects with liver cirrhosis of different aetiologies when compared with healthy controls and increased dependent on Child-Pugh classification. In subjects with alcoholic steatohepatitis, systemic anti-TNF-alpha treatment caused a significant decrease in circulating adiponectin. Adiponectin concentrations were similar in portal, hepatic and peripheral veins. No correlation between adiponectin levels and insulin resistance was found in any patient group. CONCLUSIONS: Our data suggest that circulating adiponectin is increased in liver cirrhosis independent of the aetiology of liver disease. We suggest that high adiponectin levels in chronic liver disease might reflect one of the body's anti-inflammatory mechanisms in chronic liver diseases.

Hepatic lipase polymorphism and increased risk of peripheral arterial disease.

BACKGROUND: Hepatic lipase plays a key role in the metabolism of pro-atherogenic and anti-atherogenic lipoproteins affecting their plasma level as well as their physico-chemical properties. We hypothesized single nucleotide polymorphisms in the promoter region of the hepatic lipase gene to be associated with an increased risk for peripheral arterial disease (PAD). METHODS: A total of 241 patients with PAD and 241 controls matched for sex and age (+/-2 years) were genotyped cross-sectionally for the --250 single nucleotide polymorphism in the hepatic lipase promoter. RESULTS. The frequency for the -250 A allele in patients with PAD was 0.203, whereas it was 0.147 in the controls (P=0.022). Hepatic lipase promoter polymorphism distribution remained significantly different between cases and controls after multivariate logistic regression analysis (P=0.021). The odds ratio of the -250 A hepatic lipase allele for the PAD was 1.69 (95% confidence interval of 1.08-2.64), when adjusted for current smoking, arterial hypertension, cholesterol, triglycerides, HbA(1C), total homocysteine and high sensitivity C-reactive protein. CONCLUSION: Previous data in patients with ischaemic heart disease have suggested a pro-atherogenic role of low hepatic lipase levels. Our results extend these data to the vascular territory of the lower limbs, such that hepatic lipase promoter variation represents a genetic risk factor of PAD.

Adiponectin and its receptors in non-alcoholic steatohepatitis.

BACKGROUND: Adiponectin, an adipocyte derived polypeptide, has been shown to alleviate steatosis and inflammation in mice with non-alcoholic fatty liver disease. AIM: In the present study, we wished to define liver expression of adiponectin and its receptors in morbidly obese patients undergoing bariatric surgery. Patients with non-alcoholic steatohepatitis (NASH) or simple steatosis were investigated to test whether dysregulation of this system might be involved in these disorders. PATIENTS AND METHODS: Liver mRNA expression of adiponectin and its recently cloned receptors RI and RII (adipoRI and adipoRII) were analysed by fluorescence based real time polymerase chain reaction in 13 patients with NASH and nine with simple steatosis. Adiponectin and adipoRII protein expression were assessed by immunohistochemistry in a subgroup of patients. RESULTS: Adiponectin and adipoRII mRNA expression were significantly reduced in liver biopsies of patients with NASH compared with simple steatosis while no difference was found in adipoRI mRNA expression. In NASH, adipoRII mRNA expression was negatively correlated with serum aspartate aminotransferase levels, serum alanine aminotransferase levels, and grade of fibrosis. Liver adiponectin protein expression was mainly found in endothelial cells of portal vessels and liver sinusoids whereas adipoRII expression was seen in hepatocytes only. Adiponectin and adipoRII staining were lower in biopsies of subjects with NASH compared with simple steatosis. CONCLUSION: Reduced hepatic expression of adiponectin and adipoRII might be of pathophysiological relevance in non-alcoholic fatty liver diseases.

A patient with insidious onset of exertional dyspnoea.

The case history is presented of a 42 year old woman with pulmonary artery occlusion due to tuberculous vasculitis that masqueraded as chronic pulmonary artery embolism and led to severe life threatening haemoptysis necessitating emergency pneumonectomy. It is concluded that obliterative tuberculous endarteritis of the pulmonary arteries should be considered in the differential diagnosis of any acquired obstruction of pulmonary arteries.

Effects of weight loss on PLTP activity and HDL particle size.

OBJECTIVE: Dyslipidaemia in obesity is characterized by hypertriglyceridaemia, low HDL-C levels, small, dense HDL particles and increased phospholipid transfer protein (PLTP) activity. METHODS: In the present study, we investigated PLTP activity and HDL particle size in 16 morbidly obese, middle-aged women, who underwent Swedish Adjustable Gastric Banding surgery. Study subjects were tested within 2 months before and 1 y after surgery. PLTP activity was determined by exogenous substrate assay and HDL particle size by gradient gel electrophoresis, respectively. RESULTS: Pronounced weight loss after gastric banding surgery resulted in a significant decrease of PLTP activity from 8.42+/-2.04 to 7.43+/-2.21 micromol/ml/h (P=0.02). The size of HDL(2) particles increased signficantly from 14.04+/-0.86 to 14.28+/-0.64 nm (P=0.02) after body weight reduction, while no change in HDL(3) particle size was apparent. DISCUSSION: Our results suggest that dyslipidaemia in obesity is--at least partially--reversible by weight loss. We hypothesize that reduction of PLTP activity and increase of HDL particle size are important component factors in converting the atherogenic lipoprotein profile of obese subjects into a less atherogenic profile with weight loss.

Molecular characterization of rabbit scavenger receptor class B types I and II: portal to central vein gradient of expression in the liver.

To further elucidate the role of scavenger receptor class B type I (SR-BI) in reverse cholesterol transport and in atherogenesis, we performed studies in the rabbit, an animal model displaying a lipoprotein profile similar to that of human, expressing cholesteryl ester transfer protein in plasma and having been demonstrated to be susceptible to atherosclerosis. In this report, we describe for the first time the isolation and characterization of rabbit cDNA fragments encoding SR-BI and scavenger receptor class B type II (SR-BII). Development of an isoform-specific Taqman Real Time PCR system and generation of isoform-specific polyclonal antibodies allowed us to measure SR-BI and SR-BII expression in various rabbit organs on mRNA and protein levels, respectively. We found the highest expression of SR-BI in adrenal gland, liver, and proximal intestine; lesser expression was found in appendix and spleen. Immunohistochemical staining of frozen sections showed SR-BI expression in the cortex but not in the medulla of adrenal gland. An increasing portal to central vein gradient of expression was found within the hepatic lobule. As shown in this report, identification and characterization of SR-BI expression in the rabbit affords a powerful tool to elucidate the role of SR-BI in cholesterol homeostasis and atherogenesis in human.

Resistin messenger-RNA expression is increased by proinflammatory cytokines in vitro.

Resistin is a recently discovered polypeptide that induces insulin resistance in rodents. While in rodents resistin is predominantly expressed in adipocytes, in humans peripheral blood mononuclear cells (PBMC) seem to a be a major source of resistin. In the present study, we show that in human PBMC resistin mRNA expression-determined by fluorescence-based real-time polymerase chain reaction-is strongly increased by the proinflammatory cytokines interleukin (IL)-1, IL-6, tumor necrosis factor alpha (TNF-alpha), and also by lipopolysaccharides (LPS), respectively, while no effect was found by interferon-gamma (IFN-gamma) or leptin. Our results suggest that in humans resistin may be a link in the well-known association between inflammation and insulin resistance.

Plasma amine oxidase: a postulated cardiovascular risk factor in nondiabetic obese patients.

Increased activity of semicarbazide-sensitive plasma amine oxidase (SSAO), an enzyme converting various amines, has been implicated in the generation of endothelial damage through formation of cytotoxic reaction products. We investigated if SSAO activity is elevated in morbidly obese patients, which might contribute to the increased cardiovascular risk associated with obesity. SSAO activity was determined in 74 nondiabetic, obese patients (median body mass index [BMI]: 42.9 kg/m(2)) and in 32 healthy, non-obese controls (median BMI: 23.3 kg/m(2)) using a radiometric assay based on the conversion of [(14)C]benzylamine. SSAO and parameters of glucose and lipid metabolism were compared for subgroups of obese patients with normal (n = 49) and impaired (n = 25) glucose tolerance using nonparametric statistical tests. Median SSAO activity was 434 microU/mL in obese patients, which was significantly higher than in healthy, non-obese controls (median SSAO activity: 361 microU/mL). Median SSAO activity in patients with normal and impaired glucose tolerance was 423 and 464 microU/mL, respectively. SSAO activity was not correlated with any other clinical or laboratory parameters characteristic of the metabolic alterations associated with obesity. Elevated SSAO activity is found in nondiabetic, morbidly obese patients and might be an interesting independent risk factor for obesity-related cardiovascular morbidity. Long-term follow-up of SSAO and its possible role in pathogenic events is warranted since intervention with specific SSAO inhibitors is available.

Phospholipid and cholesteryl ester transfer are increased in lipoprotein lipase deficiency.

OBJECTIVES: Phospholipid transfer protein (PLTP) and cholesteryl ester transfer protein (CETP) are key enzymes in lipoprotein metabolism by mediating the transfer and exchange of phospholipids (PL) and neutral lipids between lipoproteins. Lipoprotein lipase (LPL) deficiency is associated with low HDL-cholesterol (HDL-C) levels in both, the homozygous and heterozygous state. In the present study we set out to investigate the role of lipid transfer proteins, which are known to strongly determine HDL-C levels, in LPL deficiency. DESIGN/SUBJECTS: Phospholipid acceptor and donor properties of lipoproteins, PLTP activity, CETP mass, activity and cholesteryl ester (CE) transfer were determined in two homozygous and six heterozygous LPL-deficient subjects and in 10 healthy, normolipidaemic controls, respectively. RESULTS: The HDL isolated from LPL-deficient subjects showed strongly increased PL-acceptance when compared with controls (homozygotes versus heterozygotes versus control: 26.46 +/- 15.26 vs. 3.41 +/- 1.61 vs. 1.89 +/- 0.33 micromol mL-1 h-1/micromol mL-1 PL; all P < 0.05). Phospholipid transfer from apolipoprotein B containing lipoproteins was increased in heterozygotes when compared with controls (46.66 +/- 23.3 vs. 28.91 +/- 18.05 micromol mL-1 h-1/micromol mL-1 PL, P = 0.05). PLTP activity, however, was similar in LPL-deficient subjects and controls. CETP mass was highest in homozygotes, whilst enzyme activity was similar in LPL-deficient subjects and controls. CE transfer was highest in homozygotes (72.5 +/- 8.8%) and lowest in controls (28.7 +/- 5.2%, P < 0.01). CONCLUSIONS: In conclusion, PL and CE transfer are increased in LPL deficiency and thus, partly explain low HDL-levels in LPL-deficient subjects. Enhanced transfer seems rather to be the result of altered lipoprotein composition and concentration than altered enzyme activity. Our findings on mechanisms leading to low HDL-C levels might show another aspect in atherogenesis in LPL deficiency.

Relationship between cholesteryl ester transfer protein and atherogenic lipoprotein profile in morbidly obese women.

OBJECTIVE: Obesity is associated with increased morbidity and mortality from atherosclerotic disease. Lipid abnormalities contribute to the increased relative risk in obese subjects. Cholesteryl ester transfer protein (CETP) mass is increased in these patients and might mediate the atherogenic lipoprotein pattern observed in obesity. METHODS AND RESULTS: Twenty-one morbidly obese, middle-aged, female subjects participated in this prospective study. Subjects were examined before and 1 year after surgical treatment. Fat mass was determined by body impedance analysis; CETP mass, by ELISA; CETP activity, by exogenous substrate assay; and LDL particle diameter, by gradient gel electrophoresis. Mean weight loss after 1 year was 28.7 kg; mean fat mass loss was 22.6 kg. Mean CETP mass decreased from 1.81 to 1.32 microg/mL (P=0.008); mean CETP activity decreased from 244 to 184 nmol x mL(-1) x h(-1) (P=0.004); and in parallel, the mean diameter of LDL particles increased (256.8 to 258.4 A, P=0.04). CONCLUSIONS: We conclude that weight loss is associated with a pronounced decrease in CETP mass and activity and a consistent increase in LDL particle diameter. After 1 year of this prospective study in morbidly obese subjects undergoing weight loss by surgical treatment, it has been determined that some features of the atherogenic lipoprotein profile can be reversed.

Markers of chronic inflammation and obesity: a prospective study on the reversibility of this association in middle-aged women undergoing weight loss by surgical intervention.

BACKGROUND: Human adipose tissue expresses and releases proinflammatory cytokines and these measures of chronic inflammation have recently been associated with obesity. HYPOTHESIS: To test whether the proinflammatory state is reversible in subjects undergoing weight loss by surgical measures. SUBJECTS AND METHODS: Twenty morbidly obese women participated in this prospective study. Subjects were examined for fat mass, high-sensitive C-reactive protein (hs-CRP), interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) before and 1 y after Swedish adjustable gastric banding. RESULTS: Anthropometric measures displayed a significant reduction of the body mass index (BMI) from 41.6+/-5.4 to 30.8+/-6.1 kg/m(2) and the fat mass from 53.9+/-10.3 to 29.8+/-12.1 kg (mean+/-s.d.). Hs-CRP levels decreased significantly from 1.33+/-1.21 mg/dl in pre-gastric banding subjects to 0.40+/-0.61 mg/dl in post-gastric banding subjects, respectively. IL-6 and TNF-alpha levels did not differ significantly between pre- and post-gastric banding subjects. CONCLUSIONS: We speculate that in these patients the marked reduction in C-reactive protein might be beneficial in reducing their cardiovascular risk and is not solely mediated by IL-6 and TNF-alpha.
