Abstract
BACKGROUND Diabetes mellitus (DM) is the most common metabolic disorder in pregnancy. Women with Type 2 DM seems to have no better perinatal outcomes than those with Type 1 DM. METHODS Single-center prospective cohort observational study. Pregnant women with diabetes (141 with Type 1 DM and 124 with Type 2 DM) that were followed in the university hospital between 2009 and 2021 were included in this study. Clinical data and obstetric and perinatal outcomes were collected. RESULTS As expected, women with Type 1 DM were younger and had a longer duration of diabetes than women with Type 2 DM. Obesity and chronic hypertension were higher in the group of women with Type 2 DM and their value of HbA1c in the second and third trimesters were lower than in Type 1 DM. No differences in prematurity were found, but more extreme prematurity was observed in Type 2 DM, as well as a higher rate of congenital malformations. The frequency of hypoglycemia and the weight of the newborn was higher in Type 1 DM. The maternal independent factors related to the weight of the newborn were: the glycemic control at the third trimester, the weight gain during pregnancy, and pregestational BMI. CONCLUSIONS Newborns born to mothers with Type 1 DM were larger and had a higher frequency of hypoglycemia, while congenital malformations and precocious preterm was more associated to Type 2 DM. Metabolic control, weight gain and pregestational weight were important determinants of both obstetric and neonatal complications.

Abstract
Our aim was to evaluate whether fatty liver index (FLI) is associated with the risk of type 2 diabetes (T2DM) development within the Spanish adult population and according to their prediabetes status; additionally, to examine its incremental predictive value regarding traditional risk factors. A total of 2260 subjects (Prediabetes: 641 subjects, normoglycemia: 1619 subjects) from the Di@bet.es cohort study were studied. Socio-demographic, anthropometric, clinical data and survey on habits were recorded. An oral glucose tolerance test was performed and fasting determinations of glucose, lipids and insulin were made. FLI was calculated and classified into three categories: Low (< 30), intermediate (30–60) and high (> 60). In total, 143 people developed diabetes at follow-up. The presence of a high FLI category was in all cases a significant independent risk factor for the development of diabetes. The inclusion of FLI categories in prediction models based on different conventional T2DM risk factors significantly increase the prediction power of the models when all the population was considered. According to our results, FLI might be considered an early indicator of T2DM development even under normoglycemic condition. The data also suggest that FLI could provide additional information for the prediction of T2DM in models based on conventional risk factors.

Abstract
PURPOSE Recent studies point to adipose-derived stem cells (ASCs) as a link between obesity and cancer. We aimed to determine whether survivin, which is highly secreted by ASCs from subjects with obesity, might drive a pro-tumoral phenotype in macrophages. METHODS The effect of ASC conditioned medium on the macrophage phenotype was assessed by expression studies. Survivin intracellular localization and internalization were examined by subcellular fractionation and immunofluorescence, respectively. Loss- and gain-of-function studies were performed using adenoviral vectors, and gene expression patterns, migration and invasion capacities of cancer cells were examined. Heterotypic cultures of ASCs, macrophages and cancer cells were established to mimic the tumor microenvironment. Survivin-blocking experiments were used to determine the impact of survivin on both macrophages and cancer cells. Immunohistochemical analysis of survivin was performed in macrophages from ascitic fluids of cancer patients and healthy controls. RESULTS We found that obese-derived ASCs induced a phenotypic switch in macrophages characterized by the expression of both pro- and anti-inflammatory markers. Macrophages were found to internalize extracellular survivin, generating hybrid macrophages with a tumor-associated phenotype that included secretion of survivin. Exogenous expression of survivin in macrophages generated a similar phenotype and enhanced the malignant characteristics of cancer cells by a mechanism dependent on survivin phosphorylation at threonine 34. Survivin secreted by both ASCs from subjects with obesity and tumor-associated macrophages synergistically boosted the malignancy of cancer cells. Importantly, survivin was mainly detected in ascites-associated macrophages from patients with a malignant diagnosis. CONCLUSION Our data indicate that survivin may serve as a molecular link between obesity and cancer and as a novel marker for tumor-associated macrophages.

Abstract
Our aim was to determine the incidence of type 2 diabetes mellitus in a nation-wide population based cohort from Spain (di@bet.es study). The target was the Spanish population. In total 5072 people older than 18 years,were randomly selected from all over Spain). Socio-demographic and clinical data, survey on habits (physical activity and food consumption) and weight, height, waist, hip and blood pressure were recorder. A fasting blood draw and an oral glucose tolerance test were performed. Determinations of serum glucose were made. In the follow-up the same variables were collected and HbA1c was determined. A total of 2408 subjects participated in the follow-up. In total, 154 people developed diabetes (6.4% cumulative incidence in 7.5 years of follow-up). The incidence of diabetes adjusted for the structure of age and sex of the Spanish population was 11.6 cases/1000 person-years (IC95% = 11.1–12.1). The incidence of known diabetes was 3.7 cases/1000 person-years (IC95% = 2.8–4.6). The main risk factors for developing diabetes were the presence of prediabetes in cross-sectional study, age, male sex, obesity, central obesity, increase in weight, and family history of diabetes. This work provides data about population-based incidence rates of diabetes and associated risk factors in a nation-wide cohort of Spanish population.

Abstract
Antibiotic resistance mediated by bacterial production of extended-spectrum beta-lactamase (ESBL) is a global threat to public health. ESBL resistance is most commonly hospital-acquired; however, infections acquired outside of hospital settings have raised concerns over the role of livestock and wildlife in the zoonotic spread of ESBL-producing bacteria. Only limited data are available on the circulation of ESBL-producing bacteria in animals. Here, we report ESBL-producing Escherichia coli in wild common vampire bats Desmodus rotundus and livestock near Lima, Peru. Molecular analyses revealed that most of this resistance resulted from the expression of blaCTX-M-15 genes carried by plasmids, which are disseminating worldwide in hospital settings and have also been observed in healthy children of Peru. Multilocus sequence typing showed a diverse pool of E. coli strains carrying this resistance that were not always host species-specific, suggesting sharing of strains between species or infection from a common source. This study shows widespread ESBL resistance in wild and domestic animals, supporting animal communities as a potential source of resistance. Future work is needed to elucidate the role of bats in the dissemination of antibiotic-resistant strains of public health importance and to understand the origin of the observed resistance.

Abstract
Coiled-coil domain-containing 80 (CCDC80) is an adipocyte-secreted protein that modulates glucose homeostasis in response to diet-induced obesity in mice. The objective of this study is to analyze the link between human CCDC80 and obesity. CCDC80 protein expression was assessed in paired visceral (VAT) and subcutaneous (SAT) adipose tissue from 10 subjects (BMI range 22.4-38.8 kg/m2). Circulating CCDC80 levels were quantified in serum samples from two independent cross-sectional cohorts comprising 33 lean and 15 obese (cohort 1) and 32 morbid obese (cohort 2) male subjects. Insulin sensitivity, insulin secretion and blood neutrophil count were quantified in serum samples from both cohorts. Additionally, circulating free IGF-1 levels and oral glucose tolerance tests (OGTT) were assessed in cohort 1 whereas C-reactive protein levels and degree of atherosclerosis and hepatic steatosis were studied in cohort 2. In lean subjects, total CCDC80 protein content assessed by immunoblotting was lower in VAT than in SAT. In obese patients, CCDC80 was increased in VAT (P<0.05), but equivalent in SAT compared with lean counterparts. In cohort 1, serum CCDC80 correlated negatively with the acute insulin response to glucose and IGF1 levels, and positively with blood neutrophil count, independently of BMI, but not with insulin sensitivity. In cohort 2, serum CCDC80 was positively linked to the inflammatory biomarker C-reactive protein (r=0.46; P=0.009), atherosclerosis (carotid intima-media thickness, r=0.62; P<0.001) and hepatic steatosis (ANOVA P=0.025). Overall, these results suggest for the first time that CCDC80 may be a component of the obesity-altered secretome in VAT and could act as an adipokine whose circulant levels are linked to glucose tolerance derangements and related to inflammation-associated chronic complications.

Abstract
Very little information is available on the involvement of newly characterized adipokines in human immunodeficiency virus (HIV)/antiretroviral therapy (ART)-associated lipodystrophy syndrome (HALS). Our aim was to determine whether apelin, apelin receptor, omentin, RBP4, vaspin and visfatin genetic variants and plasma levels are associated with HALS. We performed a cross-sectional multicentre study that involved 558 HIV type 1-infected patients treated with a stable highly active ART regimen, 240 of which had overt HALS and 318 who did not have HALS. Epidemiologic and clinical variables were determined. Polymorphisms in the apelin, omentin, RBP4, vaspin and visfatin genes were assessed by genotyping. Plasma apelin, apelin receptor, omentin, RBP4, vaspin and visfatin levels were determined by enzyme-linked immunosorbent assay in 163 patients (81 with HALS and 82 without HALS) from whom stored plasma samples were available. Student's t test, one-way ANOVA, chi-square test, Pearson and Spearman correlations and linear regression analysis were used for statistical analyses. There were no associations between the different polymorphisms assessed and the HALS phenotype. Circulating RBP4 was significantly higher (p < 0.001) and plasma omentin was significantly lower (p 0.001) in patients with HALS compared to those without HALS; differences in plasma levels of the remaining adipokines were nonsignificant between groups. Circulating RBP4 concentration was predicted independently by the presence of HALS. Apelin and apelin receptor levels were independently predicted by body mass index. Visfatin concentration was predicted independently by the presence of acquired immunodeficiency syndrome. HALS is associated with higher RBP4 and lower omentin in plasma. These two adipokines, particularly RBP4, may be a link between HIV/ART and fat redistribution syndromes.

Abstract
Metallocarboxypeptidases (MCPs) are zinc-dependent exoproteases that have been for long considered benchmark enzymes, perform a wide range of physiological roles and have been regarded as interesting drug targets. Several crystal structures of MCPs in complex with protein and small molecular weight inhibitors have recently been obtained providing a framework for understanding the binding properties of these ligands. Much of the latest research focused on carboxypeptidase U or thrombin-activable fibrinolysis inhibitor (CPU/TAFI) which has fueled new designs in the field of cardiovascular drugs. Further, new details on the catalytic mechanism of MCPs have emerged from recent crystal structures of covalently modified forms and the pace of investigations on inhibitors has been steadily fastening in the last years. This paper will focus on the latest research carried on metallocarboxypeptidase small molecular weight inhibitors as drug candidates and will give an update of protein inhibitors to emphasize the growing interest for products isolated from natural sources.

Abstract
BACKGROUND AND AIMS Mediterranean diet (MedDiet) is causally related to diabetes and is a dietary pattern recommended to individuals with diabetes. We investigated MedDiet adherence in individuals with prediabetes and unknown (PREDM/UKDM) or known diabetes (KDM) compared to those with normal glucose metabolism (NORMAL). METHODS This was a national, population-based, cross-sectional, cluster-sampling study. MedDiet adherence was scored (MedScore, mean ± SD 24 ± 5) using a qualitative food frequency questionnaire. Logistic regression was used to examine the association between MedScore and PREDM/UKDM or KDM versus control subjects. RESULTS We evaluated 5,076 individuals. Mean age was 50 years, 57% were female, 826 (582/244) were PREDM/UKDM, 478 were KDM and 3,772 were NORMAL. Mean age increased across MedScore tertiles (46, 51 and 56 years, p < 0.0001). Higher age-adjusted adherence to MedDiet (5-unit increment in the MedScore) was associated with lower and nondifferent odds (OR, 95% CI) of prevalent PREDM/UKDM (0.88, 0.81-0.96, p = 0.001) and KDM (0.97, 0.87-1.07, p = 0.279), respectively, compared to individuals in the NORMAL group. CONCLUSIONS In a representative sample of the whole Spanish population, MedDiet adherence is independently associated with PREDM/UKDM. Therapeutic intervention may be, in part, responsible for the lack of differences in adherence observed between the KDM and NORMAL groups. However, reverse causation bias cannot be ruled out in cross-sectional studies.

Abstract
AIM This study investigated the relationship between endothelial dysfunction (ED) and arterial stiffness (AS) in adults with type 1 diabetes and no clinical cardiovascular (CV) disease. METHODS A total of 68 patients with type 1 diabetes and 68 age- and gender-matched healthy (non-diabetic) subjects were evaluated. ED was assessed by reactive hyperaemia peripheral arterial tonometry (RH-PAT) and by serum concentrations of soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1) and E-selectin. AS was assessed by aortic pulse wave velocity (aPWV). All statistical analyses were stratified by gender. RESULTS Adults with type 1 diabetes had RH-PAT index scores similar to those of their matching controls [men: 1.55 (1.38-1.98)% versus 1.61 (1.40-2.17)%, P=0.556; women: 2.07 (1.55-2.31)% versus 2.08 (1.79-2.49)%; P=0.215]. However, after adjusting for potential confounders, type 1 diabetes emerged as the main determinant of the RH-PAT index in women. Also, differences between genders in both the controls and type 1 diabetes patients disappeared. Men with diabetes had higher serum concentrations of E-selectin, and women had higher serum concentrations of sICAM-1, sVCAM-1 and E-selectin than their respective controls. However, after adjusting for potential confounders, only the differences in sICAM-1 (women) and E-selectin (both genders) remained significant. No association was found between aPWV and the RH-PAT index and ED markers after adjusting for CV risk factors. CONCLUSION ED was increased in adults with type 1 diabetes compared with age-matched non-diabetic subjects. Also, gender differences in ED were lost in type 1 diabetes. However, ED was not associated with AS after adjusting for potential confounders. These findings suggest that ED occurs earlier than AS in type 1 diabetes.

Abstract
BACKGROUND Many patients with major depression refer a decreased appetite and weight loss among their symptoms. Peptide YY (PYY) and ghrelin belong to the family of peptides of the gut-brain axis implicated in the regulation of appetite and energy metabolism. PYY stimulates a powerful central satiety response and ghrelin increases food intake and weight gain. Brain-derived neurotrophic factor (BDNF) also contributes to the central control of food intake as an anorexigenic factor. AIM To study fasting plasma total and acylated ghrelin, plasma PYY and serum BDNF levels in patients with major depression with weight loss as one of their symptoms and compare them with matched healthy controls. SUBJECTS AND METHODS Fifteen adult patients, 9 male and 6 female, with recent diagnosis of major depression, and 16 healthy adult subjects, matched by age and anthropometric parameters were studied. All depressed patients referred weight loss and were not under antidepressant therapy. Fasting total PYY, total ghrelin and acylated ghrelin and BDNF were determined. RESULTS Fasting total PYY was higher in patients than controls (2.01±0.09 vs 1.29±0.16 pmol/l). There were no differences in fasting total ghrelin, acylated ghrelin or BDNF levels. CONCLUSIONS Major depressed patients, with weight loss at diagnosis, showed higher fasting plasma PYY levels that could contribute to their reduced appetite.

Abstract
To investigate the role of HbA1c in postpartum reclassification of gestational diabetes (GDM) we studied 364 women with GDM attending the postpartum reclassification assessment of their glucose tolerance status. A 75-g oral glucose tolerance test (OGTT) was performed and HbA1c was determined. Diabetes was diagnosed in 12 (3.3%), 7 (1.9%) and 2 (0.6%) women according to the fasting plasma glucose (FPG) and/or the 2-hour OGTT, the FPG alone and HbA1c levels, respectively. The sensitivity and specificity for HbA1c to diagnose diabetes was 16.7% and 100%, respectively, for FPG and OGTT criteria. The combination of a cutoff value of 5.5% for HbA1c and FPG allowed us to identify 95.1% of women with any kind of glucose intolerance. We conclude that in the early postpartum period, the cutoff of 6.5% for HbA1c alone has low sensitivity for the diagnosis of diabetes compared with OGTT, but the combination of FPG and HbA1c at a lower cutoff value is very useful to identify women with any kind of glucose intolerance.

A total of 120 subjects diagnosed with T1DM 14 years before were evaluated for the following: (1) sex, age, body mass index, waist-to-hip ratio (WHR), blood pressure, smoking, alcohol intake, insulin dose, HbA1c and lipid profile; (2) microvascular complications; (3) plasma concentrations of soluble fractions of tumour necrosis factor-α receptors type 1 and 2, interleukin-6, adiponectin, leptin and high-sensitivity C-reactive protein (hs-CRP); and (4) insulin resistance (estimation of the glucose disposal rate-eGDR). Those subjects with an eGDR below the median of the same sex group were classified as insulin resistant and the others as insulin sensitive. Insulin-resistant men, compared to the insulin-sensitive, had higher WHR (0.89 ± 0.08 vs. 0.83 ± 0.05; P < 0.01), higher systolic [121 (118-125) vs. 114 (108-120) mmHg; P = 0.01] and diastolic [73 (66-80) vs. 67 (70-73) mmHg; P = 0.02] blood pressures, higher HbA1c values [8.7 (8.1-9.9) vs. 7.5 (7.2-8.0) %; P < 0.01] and higher hs-CRP concentrations [1.16 (0.61-3.20) vs. 0.49 (0.31-0.82) mg/dl; P = 0.01], but no other significant differences between groups were found. Insulin-resistant women had higher WHR and HbA1c values, compared to the insulin-sensitive, but they did not have any other differences. In men, hs-CRP correlated significantly with WHR and HbA1c (r = 0.363; P = 0.016 and r = 0.317; P = 0.036, respectively), after adjusting for age, alcohol intake, smoking and microvascular complications. Insulin-resistant men with T1DM have an increase in plasma concentrations of hs-CRP. Central obesity and HbA1c are its main determinants.

Abstract
OBJECTIVES Treated HIV-1-infected patients with lipodystrophy often develop insulin resistance and proatherogenic dyslipidaemia. Zinc alpha-2 glycoprotein (ZAG) is a recently characterized adipokine which has been shown to be involved in the development of obesity and metabolic syndrome in uninfected subjects. We assessed the relationship between circulating ZAG levels and metabolic derangements in HIV-1-infected patients receiving antiretroviral drugs. METHODS Plasma ZAG levels were assessed in 222 individuals: 166 HIV-1-infected patients treated with antiretroviral drugs (77 with lipodystrophy and 89 without lipodystrophy) and 56 uninfected controls. Plasma ZAG levels were assessed by enzyme-linked immunosorbent assay (ELISA) and were correlated with fat distribution abnormalities and metabolic parameters. RESULTS HIV-1-infected patients had lower plasma ZAG levels compared with uninfected controls (P < 0.001). No differences were found in ZAG plasma levels according to the presence of lipodystrophy, components of the metabolic syndrome or type of antiretroviral treatment regimen. Circulating ZAG levels were strongly determined by high-density lipoprotein cholesterol (HDLc) in men (B = 0.644; P < 0.001) and showed a positive correlation with total cholesterol (r = 0.312; P < 0.001) and HDLc (r = 0.216; P = 0.005). CONCLUSIONS HIV-1-infected patients have lower plasma ZAG levels than uninfected controls. In infected patients, plasma ZAG levels are in close relationship with total cholesterol and HDLc.

Abstract
AIMS/HYPOTHESIS The Di@bet.es Study is the first national study in Spain to examine the prevalence of diabetes and impaired glucose regulation. METHODS A population-based, cross-sectional, cluster sampling study was carried out, with target population being the entire Spanish population. Five thousand and seventy-two participants in 100 clusters (health centres or the equivalent in each region) were randomly selected with a probability proportional to population size. Participation rate was 55.8%. Study variables were a clinical and demographic structured survey, lifestyle survey, physical examination (weight, height, BMI, waist and hip circumference, blood pressure) and OGTT (75 g). RESULTS Almost 30% of the study population had some carbohydrate disturbance. The overall prevalence of diabetes mellitus adjusted for age and sex was 13.8% (95% CI 12.8, 14.7%), of which about half had unknown diabetes: 6.0% (95% CI 5.4, 6.7%). The age- and sex-adjusted prevalence rates of isolated impaired fasting glucose (IFG), isolated impaired glucose tolerance (IGT) and combined IFG-IGT were 3.4% (95% CI 2.9, 4.0%), 9.2% (95% CI 8.2, 10.2%) and 2.2% (95% CI 1.7, 2.7%), respectively. The prevalence of diabetes and impaired glucose regulation increased significantly with age (p < 0.0001), and was higher in men than in women (p < 0.001). CONCLUSIONS/INTERPRETATION The Di@bet.es Study shows, for the first time, the prevalence rates of diabetes and impaired glucose regulation in a representative sample of the Spanish population.

Abstract
Objective. To evaluate the association between diabetes mellitus and health-related quality of life (HRQOL) controlled for several sociodemographic and anthropometric variables, in a representative sample of the Spanish population. Methods. A population-based, cross-sectional, and cluster sampling study, with the entire Spanish population as the target population. Five thousand and forty-seven participants (2162/2885 men/women) answered the HRQOL short form 12-questionnaire (SF-12). The physical (PCS-12) and the mental component summary (MCS-12) scores were assessed. Subjects were divided into four groups according to carbohydrate metabolism status: normal, prediabetes, unknown diabetes (UNKDM), and known diabetes (KDM). Logistic regression analyses were conducted. Results. Mean PCS-12/MCS-12 values were 50.9 ± 8.5/ 47.6 ± 10.2, respectively. Men had higher scores than women in both PCS-12 (51.8 ± 7.2 versus 50.3 ± 9.2; P < 0.001) and MCS-12 (50.2 ± 8.5 versus 45.5 ± 10.8; P < 0.001). Increasing age and obesity were associated with a poorer PCS-12 score. In women lower PCS-12 and MCS-12 scores were associated with a higher level of glucose metabolism abnormality (prediabetes and diabetes), (P < 0.0001 for trend), but only the PCS-12 score was associated with altered glucose levels in men (P < 0.001 for trend). The Odds Ratio adjusted for age, body mass index (BMI) and educational level, for a PCS-12 score below the median was 1.62 (CI 95%: 1.2-2.19; P < 0.002) for men with KDM and 1.75 for women with KDM (CI 95%: 1.26-2.43; P < 0.001), respectively. Conclusion. Current study indicates that increasing levels of altered carbohydrate metabolism are accompanied by a trend towards decreasing quality of life, mainly in women, in a representative sample of Spanish population.

Abstract
Plasma acutephase protein pentraxin 3 (PTX3) concentration is dysregulated in human obesity and metabolic syndrome. Here, we explore its relationship with insulin secretion and sensitivity, obesity markers, and adipose tissue PTX3 gene expression. Plasma PTX3 protein levels were analyzed in a cohort composed of 27 lean [body mass index (BMI) ≤ 25 kg/m(2)] and 48 overweight (BMI 25-30 kg/m(2)) men (cohort 1). In this cohort, plasma PTX3 was negatively correlated with fasting triglyceride levels and insulin secretion after intravenous and oral glucose administration. Plasma PTX3 protein and PTX3 gene expression in visceral (VAT) and subcutaneous (SAT) whole adipose tissue and adipocyte and stromovascular fractions were analyzed in cohort 2, which was composed of 19 lean, 28 overweight, and 15 obese subjects (BMI >30 kg/m(2)). An inverse association with body weight and waist/hip ratio was observed in cohort 2. In VAT depots, PTX3 mRNA levels were higher in subjects with BMI >25 kg/m(2) than in lean subjects, positively correlated with IL-1β mRNA levels, and higher in the adipocyte than stromovascular fraction. Human preadipocyte SGBS cell line was used to study PTX3 production in response to factors that obesity entails. In SGBS adipocytes, PTX3 gene expression was enhanced by IL-1β and TNFα but not IL-6 or insulin. In conclusion, the negative correlation between PTX3 and glucose-stimulated insulin secretion suggests a role for PTX3 in metabolic control. PTX3 gene expression is upregulated in VAT depots in obesity, despite lower plasma PTX3 protein, and by some proinflammatory cytokines in cultured adipocytes.

Abstract
BACKGROUND The storage capacity of adipose tissue may be an important factor linking obesity, insulin resistance (IR), and associated morbidities. The aim of this study was to analyze the expression of lipogenic and lipolytic genes in adipose tissue and the influence of IR. METHODS We studied the mRNA expression of peroxisome proliferator-activated receptor-γ (PPARγ) and lipogenic and lipolytic enzymes in the visceral (VAT) and subcutaneous adipose tissue (SAT) from 23 morbidly obese patients (MO; 13 with low IR and ten with high IR) and from 15 healthy, lean controls. RESULTS In the VAT and SAT from the MO, we found an increased expression of PPARγ (p = 0.001 and p = 0.022, respectively), acyl-coenzyme A (CoA)/cholesterol acyltransferase (p < 0.001 and p < 0.001), aquaporin 7 (p < 0.001 and p = 0.003), and adipose triglyceride lipase (p < 0.001 and p < 0.001) and a reduced expression of acetyl-coenzyme A carboxylase (p = 0.004 and p < 0.001), independently of the state of IR. The expression of phosphoenolpyruvate carboxykinase and acyl-CoA synthetase, however, was significantly lower in the MO with high IR (p < 0.05). Glycerol kinase (p = 0.010), hormone-sensitive lipase (p < 0.001), and perilipin (p = 0.006) were only significantly increased in VAT. Acyl-CoA synthetase (p = 0.012) and fatty acid binding protein-4 (p = 0.003) were only significantly decreased in SAT. The expression of the genes studied was only greater in the SAT than the VAT in the controls. CONCLUSION Our results show an upregulation of genes facilitating triglyceride/fatty acid cycling and a reduction in the genes involved in de novo synthesis of fatty acids in morbid obesity. The expression of some of the genes studied seems to be related with the state of IR. VAT and SAT differ metabolically and also between controls and MO.

Abstract
BACKGROUND Retinol-binding protein 4 (RBP4) is known to be involved in obesity-associated insulin resistance. AIMS To study the relationships between the degree of adiposity, insulin resistance indices, plasma lipids, inflammatory parameters, glucose intolerance (GI) status and plasma RBP4 levels in obese children and adolescents. PATIENTS AND METHODS Prospective study comprising 199 obese patients (95 boys) aged 8-16 years (11.8 +/- 1.9). Fifty-three subjects (23 boys) of similar mean age, 11.3 +/- 2.1 years, served as controls. BMI, waist and hip circumferences, plasma lipids, and inflammatory parameters were measured and patients underwent an oral glucose tolerance test. Plasma RBP4 levels were determined by nephelometry. RESULTS Plasma RBP4 levels (pg/ml) in obese patients with GI (n = 15) were higher (45.0 +/- 14.1) compared with those of obese patients without GI (35.9 +/- 11.7, p = 0.02; n = 184) and controls (31.5 +/- 12.3, p = 0.04) in a generalized linear model adjusted for age, sex, BMI and pubertal status. A negative correlation was found between the skeletal muscle insulin resistance index and RBP4; positive correlations were found between the RBP4 and BMI Z-score (r = 0.213, p < 0.001), waist circumferences (r = 0.135, p < 0.05), plasma triglycerides (r = 0.187, p = 0.005) and apolipoprotein B (0.187, p = 0.007). CONCLUSIONS Our results suggest a direct relationship between circulating insulin and RBP4 levels, which indicates that this protein might contribute to the development of muscle insulin resistance.

Abstract
CONTEXT AQP7 is considered to be the sole adipose glycerol channel, and its regulation is crucial for glycemia control. OBJECTIVES In this work, we aimed to further characterize AQP7 in human adipose tissue in obesity and type 2 diabetes (T2D): 1) to assess AQP7 expression levels in paired abdominal adipose tissue depots (sc and visceral); 2) to relate it with gene expression of genes involved in lipid metabolism; and 3) to confirm that AQP7 is mainly expressed in the adipocytes. DESIGN We conducted a transversal study of gene expression in paired samples of sc adipose tissue (SAT) and visceral adipose tissue (VAT). PATIENTS Caucasian lean and obese subjects (n = 62, matched for age and gender) and T2D subjects (n = 11, matched for age, gender, and BMI with their control group) participated in the study. MAIN OUTCOME MEASURE We measured AQP7 expression levels in paired SAT and VAT. RESULTS We have proved the presence of AQP7 mRNA and protein in the adipocyte rather than the stromovascular fraction of adipose tissue (P = 0.001) and in mature adipocytes when differentiated in vitro. Increased AQP7 mRNA expression levels in VAT from T2D obese subjects (P < 0.05) were found. AQP7 transcript levels ratio of SAT vs. VAT changed with the presence of obesity and T2D. Interestingly, there were positive associations between AQP7 and both lipogenic and lipolytic genes in a similar manner in both adipose depots. CONCLUSIONS Taken together, these data suggest a subtle regulation between adipose depots of the sole adipose aquaporin, AQP7, which is unbalanced in obesity and T2D.

Abstract
CONTEXT Zinc-alpha2-glycoprotein (ZAG) is a soluble protein similar to the class I major histocompatibility complex heavy chain, which has been implicated in lipid catabolism. We hypothesized that ZAG mRNA expression in adipose tissue may be linked with lipolytic and adipokine gene expression and have a close relationship with clinical phenotype. OBJECTIVES The objective of the study was to analyze ZAG gene expression in human adipose tissue from lean and obese subjects. ZAG circulating plasma levels and its relationship with cardiometabolic risk factors were also studied. DESIGN Seventy-three Caucasian (43 male and 30 female) subjects were included. Plasma and adipose tissue [sc (SAT) and visceral (VAT)] from the same patient were studied. mRNA of PPARgamma, hormone-sensitive lipase (HSL), adipose triglyceride lipase, adiponectin, omentin, visfatin, and ZAG were quantified. Plasma concentrations of ZAG were determined with ELISA. RESULTS ZAG plasma levels showed a negative correlation with insulin (r = -0.39; P = 0.008) and the homeostasis model assessment for insulin resistance index (r = -0.36; P = 0.016). No differences in ZAG circulating levels according to body mass index classification were observed. ZAG expression in SAT was significantly reduced in overweight and obese individuals compared with lean subjects (P < 0.001 and P = 0.007, respectively). ZAG mRNA expression in both SAT and VAT depots were negatively correlated with many clinical and metabolic cardiovascular risk factors. After multiple linear regression analysis, SAT ZAG was mainly predicted by adiponectin mRNA expression (B = 0.993; P < 0.0001) and plasma triglyceride levels (B = -0.565; P = 0.006). VAT ZAG expression was predicted by adiponectin expression (B = 0.449; P < 0.0001), and HSL VAT expression (B = 0.180; P = 0.023). CONCLUSIONS The present study provides evidence of a role of ZAG gene in adipose tissue metabolism, with a close association with adiponectin gene expression in sc and visceral fat.

Abstract
OBJECTIVE The objective of this study was to evaluate plasma visfatin levels in thyroid dysfunction and its relationship with inflammatory, anthropometric and insulin resistance parameters. DESIGN AND PATIENTS Twenty-four hyperthyroid and 27 hypothyroid patients were studied before and after treatment. Forty-five euthyroid subjects were used as control group. MEASUREMENTS Fasting plasma visfatin, IL-6, C reactive protein, adiponectin, thyroid hormones, waist-to-hip ratio, BMI, percentage of body fat and homeostasis model insulin resistance index (HOMA-IR) were measured. RESULTS Hyperthyroid patients showed increased insulin resistance, IL-6 and visfatin levels compared with controls (3.21 +/- 3.0 vs. 1.67 +/- 0.75, P = 0.022; 3.35 +/- 0.41 vs. 2.10 +/- 0.25 pg/ml, P = 0.016; and 37.4 +/- 5.81 vs. 23.79 +/- 4.2 ng/ml, P = 0.061 respectively). After normalization of thyroid function, IL-6 levels and HOMA-IR decreased (2.35 +/- 0.37 vs. 2.10 +/- 0.25 pg/ml, P = 0.045 and 3.21 +/- 0.60 vs. 2.28 +/- 0.38, P = 0.032 respectively), while body weight, adiposity and visfatin levels increased (26.1 +/- 1.2 vs. 26.7 +/- 1.2 kg/m(2), P = 0.049; 30.9 +/- 1.6 vs. 32.2 +/- 1.6%, P = 0.007; and 37.4 +/- 5.81 vs. 63.13 +/- 8.72 ng/ml, P = 0.047 respectively). C reactive protein and adiponectin levels were similar to those of the control group. Hypothyroid patients showed high visfatin levels (40.59 +/- 3.07 vs. 29.34 +/- 4.9 ng/ml, P = 0.049) that increased after treatment (81.4 +/- 9.2 ng/ml, P = 0.001) without changes in anthropometric or insulin resistance parameters. C reactive protein, IL-6 and adiponectin levels were similar to those of the control group. No correlations between visfatin and any analysed parameter were found in either hyper- or hypothyroidism. CONCLUSION Visfatin exhibits a marked increase after normalization of thyroid function in both hyper and hypothyroid patients. We suggest that visfatin may play a role in the hormone stabilization process independent of anthropometric, inflammatory or insulin resistance variables.

Abstract #5018
Background: Detection and characterization of circulating tumor cells (CTC) in the peripheral blood of breast cancer patients could help to guide treatment decisions before the onset of overt metastasis as well as in the setting of advanced disease. The HER2 oncogene is the most prominent therapeutic target in breast cancer and shedding of the extracellular domain of this receptor seems to contribute to constitutive activation of HER2. Here we developed a novel assay to detect shedding of the extracellular domain (ECD) of the HER2 oncogene on single CTC and applied this assay to the analysis of blood from metastatic breast cancer patients.
 Material and Methods: Using a new dual fluorescent CK19/HER2-EPISPOT assay, the shedding of HER2 ECD by CTC from 49 metastatic breast cancer patients was assessed. In parallel, using the CellSearch system, the number of CTC and their HER2 expression were determined on 42 samples from metastatic breast cancer patients. A subgroup (n=34) of these patients was analyzed with both methods. This work was performed in the context of the activities of the DETECT study group.
 Results: In the CK19/HER2-EPISPOT assay 24 of 49 (48.9%) patients had CTC (mean, 12.4; median, 5; range 1-141) and among these positive patients, 7 of 24 (29.2%) showed also HER2-secreting CTC (mean, 3.3; median, 2; range, 1-14). Using the CellSearch™ system, in 23/42 (54.8%) patients CTC were found (mean, 82; median, 13; range, 1-656). HER2 staining intensity was heterogeneous even among CTC from the same patient. Regarding the samples analyzed with both methods, we found that 23.5%, 50.0%, 50.0% and 76.5% of the patients were positive with both detection methods, the EPISPOT assay only, the CellSearch™ system only and one or the other method, respectively.
 Discussion: These findings demonstrate, for the first time, that (i) CTC can secrete HER2 and (ii) HER2 secretion is not closely linked to HER2 CellSearch™ status. Both assays (i.e., EPISPOT and CellSearch™) have a comparative sensitivity and appear to be complementary for the detection and characterization of the HER2-status of CTC.

Abstract
AIM Adult subjects with Prader-Willi syndrome (PWS) may show several conditions that are associated with an activation of innate immunity such as obesity, deficient GH secretion or hypogonadism. Our aim was to study whether obese adult PWS subjects show an additional low-grade systemic inflammation (LGSI) in relation to obese adult non-PWS subjects and lean healthy control subjects before and after a standardized liquid meal. METHODS Seven obese adult PWS subjects, 7 matched obese non-PWS subjects and 7 lean healthy control subjects were studied for 6 h from the administration of a standard liquid meal. RESULTS Compared to non-PWS, PWS subjects showed higher plasma concentrations of C-reactive protein (CRP) (p=0.030), complement component C3 (p=0.018), interleukin(IL)-18 (p=0.048), and IL-6 (p=0.041) that persisted post-prandially elevated for CRP (p<0.0001), C3 (p=0.015), and IL-18 (p=0.003). Tumor necrosis factor(TNF)-alpha did not differ between the 3 groups. These results were independent from IGF-I levels, homeostasis model assessment index, and body mass index (BMI). In male subjects with PWS, testosterone levels correlated to IL-18 (r=-0,646, p=0.041). CONCLUSIONS Compared to matched non-PWS subjects, the obese PWS subjects in this study showed an additional LGSI that persisted postprandially and was independent from BMI, insulin resistance, and deficient GH secretion. However, in PWS males, high IL-18 levels were related to low testosterone concentrations.

Abstract
OBJECTIVE Interleukin-18 (IL-18) is a potent proinflammatory cytokine whose role in human obesity has recently been suggested. The aim of our study was to analyse in morbidly obese patients undergoing gastric bypass, the relationship of IL-18 with insulin resistance and with proinflammatory cytokines (tumour necrosis factor-alpha receptors, sTNFR), C-reactive protein (CRP) and with adiponectin. DESIGN Observational and prospective study. PATIENTS Sixty-five morbidly obese patients, aged 45 +/- 8.9 years, were studied before and 12 months after gastric bypass. MEASUREMENTS We analysed plasma concentrations of IL-18, sTNFR, CRP and adiponectin. RESULTS Plasma concentrations of sTNFR2, IL-18 and CRP were decreased and adiponectin significantly increased after bypass surgery. In the multiple regression analysis, preoperative values of IL-18 remained significantly associated with preoperative triglycerides (beta = 0.47, P = 0.005) and TNFR2 (beta = 0.47, P = 0.004). R(2) for the model = 0.38. Postoperative IL-18 concentrations in the multiple regression analysis were significantly associated with postoperative homeostasis model assessment of insulin resistance (HOMA-IR) (beta = 0.092, P = 0.019) and triglycerides (beta = 0.40, P = 0.036). R(2) for the model = 0.46. IL-18 did not correlate with body mass index, fat mass, fat-free mass or body fat. No relationship was either found between adiponectin and IL-18, TNFR1 and -2 and CRP. CONCLUSIONS Massive weight loss induced by gastric bypass reduces IL-18, TNFR2 and CRP. IL-18 might be a marker of the chronic inflammatory process underlying insulin resistance but its lack of association with anthropometric and body composition parameters does not support a major secretion by human adipocytes. IL-18 and sTNFR1 and -2 do not play a main role in the inhibition of the secretion of adiponectin.

Abstract
The estrogen receptor alpha (ER alpha) status of breast tumors is used to identify patients who may respond to endocrine agents such as tamoxifen. However, ER alpha status alone is not perfectly predictive, and there is a pressing need for more reliable markers of endocrine responsiveness. In this aim, we used a two-step strategy. We first screened genes of interest by a pangenomic 44 K oligonucleotide microarray in a series of ten ER alpha-positive tumors from five tamoxifen-treated postmenopausal patients who relapsed (distant metastasis) and five tamoxifen-treated postmenopausal patients who did not relapse, matched with respect to age, Scarff-Bloom-Richardson grade, lymph node status, and macroscopic tumor size. Genes of interest (n=24) were then investigated in an independent well-characterized series of ER alpha-positive unilateral invasive primary breast tumors from postmenopausal women who received tamoxifen alone as adjuvant hormone therapy after primary surgery. We identified four genes (HRPAP20, TIMELESS, PTPLB, and MGC29814) for which high mRNA levels were significantly associated with shorter relapse-free survival (log-rank test). We also showed that hormone-regulated proliferation-associated 20 kDa protein (HRPAP20) and TIMELESS are 17beta-estradiol-regulated in vitro and are ectopically expressed in OH-Tam-resistant cell lines. In conclusion, these findings point to HRPAP20 and TIMELESS as promising markers of tamoxifen resistance in women with ER alpha-positive breast tumors.

Abstract
CONTEXT Aquaporin-7 is required for efflux of glycerol from adipocytes and influences whole-body glucose homeostasis in animal studies. OBJECTIVE Our objective was to test the hypothesis that AQP7 gene expression levels may be affected by presence of obesity and type 2 diabetes in humans. DESIGN The obesity study cohort consisted of 12 lean, 22 nonseverely obese, and 13 severely obese subjects. The type 2 diabetes study cohort consisted of 17 lean and 39 obese type 2 diabetic patients. Circulating levels of plasma soluble proteins monocyte chemoattractant protein-1, TNF receptors 1 and 2, and IL-6 and glycerol were measured. The sc adipose tissue gene expression of AQP7, MCP-1, IL-6, TNFalpha, PPARgamma, and SREBP1c genes was measured by real-time PCR. AQP7 gene mutation analysis was performed. RESULTS Severely obese women showed lower AQP7 expression levels compared with lean and nonseverely obese (P < 0.001). Moreover, circulating glycerol concentration was lower in severely obese subjects, but no correlation with AQP7 adipose tissue expression was observed. AQP7 expression was negatively related with proinflammatory genes (for monocyte chemoattractant protein-1, r = -0.203 and P = 0.044; for TNFalpha, r = -0.209 and P = 0.036). Concerning adipogenic factors, AQP7 expression levels were found to be positively determined by PPARgamma mRNA expression levels (r = 0.265; P = 0.012). AQP7 expression did not show differences regarding the presence of type 2 diabetes. CONCLUSION Expression of AQP7 is down-regulated in women with severe obesity. The expression of this glycerol channel is not affected by type 2 diabetes.

Abstract
OBJECTIVE In type 1 diabetes, cardiovascular autonomic neuropathy (CAN) is associated with cardiovascular risk factors related to insulin resistance, which in turn are associated with low-grade systemic inflammation. Reduced heart rate variability (HRV) is considered one of the first indicators of CAN. Since the autonomic nervous system interacts with systemic inflammation, we evaluated CAN to study its possible association with low-grade systemic inflammation. DESIGN Cross-sectional study of a group of 120 subjects diagnosed with type 1 diabetes mellitus 14 years before. METHODS Information recorded: 1) clinical characteristics: sex, age, body mass index, waist-to-hip ratio (WHR), blood pressure (BP), smoking, alcohol intake, insulin dose, HbA1c, and lipid profile; 2) plasma levels of soluble fractions of tumour necrosis factor alpha receptors 1 and 2, IL-6, and C-reactive protein; 3) insulin resistance by estimation of the glucose disposal rate (eGDR); and 4) tests for CAN: HRV in response to deep breathing (E/I ratio), HRV in response to the Valsalva maneuver, and changes in systolic BP responding to standing. RESULTS A significant negative correlation was found between E/I ratio and plasma concentrations of IL-6 (r=-0.244, P=0.032), which remained significant after adjusting for potential confounding factors (age, sex, HbA1c, WHR, diastolic BP, triglycerides, HDL-cholesterol, retinopathy, nephropathy, peripheral neuropathy, insulin dose, and smoking; r=-0.231, P=0.039). No other significant associations were found between inflammation-related proteins, tests for CAN, and eGDR. CONCLUSIONS These findings suggest a link between low-grade inflammation and early alterations of CAN in type 1 diabetes and may be of importance in the pathogenesis of CAN and/or its clinical implications.

15571 Background: To report early and late toxicity and preliminary biochemical outcome in 345 patients with high-risk (Gleason >=7; PSA>20 or T2c-T3) clinically localized prostate cancer treated with combined high-dose-rate brachytherapy and IMRT (IMRT-HDR) to the prostate and seminal vesicles with 24–36 months of hormononal treatment (goserelin+bicalutamide) (HT). Methods: Between 12/1999 and 10/2003, 345 patients with PSA>20, Gleason score>6 and/or T2c-T3 N0 M0 prostate cancer were treated with IG-IMRT followed by HDR implant to the prostate and HT. Patients were randomly assigned to receive HT for 24 (group 1, 172 patients) or 36 months (group 2, 173 patients). Acute and late toxicities were scored by the EORTC/RTOG morbidity grading scales. Special attention to local, regional or distant recurrence, survival, late effects, PSA and testosterone levels and quality of life was done. PSA failure was defined as nadir +2.0 ng/ml. Results: All patients completed treatment. One patient included in the group 1 and none of the group 2 experienced grade 3 rectal toxicity (rectal ulcer). Seven patients in each group (4.0%) developed acute Grade 2 urinary symptoms, and none experienced urinary retention. No patient (0%) developed Grade 4 rectal complications or grade 3 or 4 urinary complications. With a median follow-up of 44 months, the 5-year actuarial PSA relapse-free survival rates for the whole group of patients was 95.7 %. No statistical differences between group 1 and 2 patients were found. Conclusions: High-dose IG-IMRT+HDR and HT was a safe and effective method of escalating the dose to the prostate without increasing the risk of late effects. Acute and late rectal and urinary complications were significantly low, compared with what has been observed with high-dose conventional, 3D-conformal or IMRT-only. Short-term PSA control rates seem to be at least comparable to those achieved with 3D-EBRT or IMRT. Both treatment regimes were very effective. Longer follow-up is needed to know if better PSA control rate are achieved with longer HT. No significant financial relationships to disclose.

Abstract
1001 Background: Metastasis is the main cause of cancer-related death. Single disseminated tumor cells (DTC) can be detected by sensitive immunocytochemical and molecular technologies, but it is still unclear whether these cells are viable and biologically active. Methods: We applied a novel enzyme-linked immunospot assay (‘EPISPOT‘) that reveals a fingerprint of specific proteins secreted from single viable epithelial tumor cells. The membrane of ELISPOT plates were coated with monoclonal antibodies against the tumor-associated marker proteins mucin-1 (MUC1) for breast cancer and prostate-specific antigen (PSA) for prostate cancer. In addition, dual fluorescent EPISPOT assays were developed to characterize MUC1+ and PSA+ cells (i.e. CK19, FGF2 secretion). Results: Even in the absence of overt metastases (stage M0), the EPISPOT assay revealed viable tumor cells in the peripheral blood of 65% of prostate cancer patients (n=31) and the bone marrow of 54% of breast cancer patients (n=37). Respective samples from non-carcinoma controls were EPISPOT- negative, whereas 80 to 100% of samples from metastatic patients (stage M1, n=40) were positive. The number of EPISPOT-positive cells in M0-patients ranged from 2 to 197 in the blood of prostate cancer patients and 1 to 262 in the bone marrow of breast cancer patients, while M1- patients showed significantly higher counts (prostate cancer, 1–684; breast cancer, 4–813). Interestingly, subsets of MUC1- or PSA-secreting cells expressed a breast stem cell-like phenotype (MUC1-/CK19+) or secreted FGF-2 as factor relevant for the growth of DTC, respectively. Conclusions: A significant fraction of cancer patients harbor viable and biologically active tumor cells in their blood and bone marrow, even in the absence of overt metastases. The multiparameter EPISPOT assay helps to identify these putative metastatic precursor cells. No significant financial relationships to disclose.

Abstract
Increased plasma concentrations of tumor necrosis factor alpha (TNFalpha) system components appear in type 2 diabetes patients with poor glycemic control. We have analyzed the expression of TNFalpha, TNFR1 and TNFR2 when monocytes and lymphocytes isolated from a group of recent onset type 2 diabetic patients, with fasting glucose levels below 7.0mM and glycated haemoglobin (Hb1Ac) in the normal range, were stimulated with high glucose or LPS endotoxin. We report, that cultured monocytes from these type 2 diabetic patients, in comparison to monocytes from non-diabetic individuals, had an enhanced response to LPS but did not respond to an acute glucose challenge (p<0.05). No differences were observed in the cultured lymphocyte fractions. These results indicate the existence of differences, elicited by LPS or high glucose related stimulus, between monocytes isolated from non-diabetic subjects or from type 2 diabetes patients.

Abstract
The estrogen receptor alpha (ERalpha) plays a critical role in the pathogenesis and clinical behavior of breast cancer. To obtain further insights into the molecular basis of estrogen-dependent forms of this malignancy, we used real-time quantitative reverse transcription (RT)-PCR to compare the mRNA expression of 560 selected genes in ERalpha-positive and ERalpha-negative breast tumors. Fifty-one (9.1%) of the 560 genes were significantly upregulated in ERalpha-positive breast tumors compared with ERalpha-negative breast tumors. In addition to well-known ERalpha-induced genes (PGR, TFF1/PS2, BCL2, ERBB4, CCND1, etc.) and genes recently identified by cDNA microarray-based approaches (GATA3, TFF3, MYB, STC2, HPN/HEPSIN, FOXA1, XBP1, SLC39A6/LIV-1, etc.), an appreciable number of novel genes were identified, many of, which were weakly expressed. This validates the use of large-scale real-time RT-PCR as a method complementary to cDNA microarrays for molecular tumor profiling. Most of the new genes identified here encoded secreted proteins (SEMA3B and CLU), growth factors (BDNF, FGF2 and EGF), growth factor receptors (IL6ST, PTPRT, RET, VEGFR1 and FGFR2) or metabolic enzymes (CYP2B6, CA12, ACADSB, NAT1, LRBA, SLC7A2 and SULT2B1). Importantly, we also identified a large number of genes encoding proteins with either pro-apoptotic (PUMA, NOXA and TATP73) or anti-apoptotic properties (BCL2, DNTP73 and TRAILR3). Surprisingly, only a small proportion of the 51 genes identified in breast tumor biopsy specimens were confirmed to be ERalpha-regulated and/or E2-regulated in vitro (cultured cell lines). Therefore, this study identified a limited number of genes and signaling pathways, which better delineate the role of ERalpha in breast cancer. Some of the genes identified here could be useful for diagnosis or for predicting endocrine responsiveness, and could form the basis for novel therapeutic strategies.

Abstract
AIMS/HYPOTHESIS Decreased sensing of the innate immune system may lead to chronic activation of the inflammatory cascade. We hypothesised that mannan-binding lectin (MBL) deficiency may confer risk of obesity and insulin resistance. MATERIALS AND METHODS We performed a cross-sectional study of MBL protein concentration (n=434) and MBL2 gene mutations (exon 1) (n=759) in association with obesity, markers of inflammation and insulin action (euglycaemic clamp, n=113), and a longitudinal study of MBL protein before and after weight loss in obese patients (n=10). We also studied the effects of MBL in vitro in muscle cells and circulating MBL-A (mouse equivalent of human MBL) in a mouse model. RESULTS Among 434 consecutive non-diabetic men, the age-adjusted serum MBL concentration was lower in obese subjects than in lean subjects (median: 959 microg/ml [interquartile range: 116.8-2,044 microg/ml] vs 1,365 [467-2,513] microg/ml; p=0.01) and was accompanied by increased serum inflammatory markers. Insulin action correlated significantly with serum MBL (r=0.49, p<0.0001). Serum MBL concentration increased by a median of 110.2% after weight loss. The change in serum concentration of MBL was positively associated with the increase in insulin sensitivity (r=0.713, p=0.021). At least one MBL2 gene mutation was present in 48.2% of obese vs 39.3% of non-obese subjects (p=0.037). The plasma concentration of MBL-A was lower in insulin-resistant obese ob/ob mice, as was the glucose/insulin ratio. Incubation of rat soleus muscle with human MBL markedly increased fatty acid oxidation. CONCLUSIONS/INTERPRETATION These findings suggest that MBL, previously thought only to be involved in inflammation and immune system function, affects metabolic pathways.

Abstract
OBJECTIVE Interleukin-18 (IL-18) is a potent pro-inflammatory cytokine with potential atherogenic properties whose role in human obesity has been recently suggested. The aim of our study was to analyze the physiologic distribution of IL-18 among sexes and all decades of the adult life in a healthy population randomly selected and to study its relationship with anthropometric, body composition measurements and leptin concentrations. We also studied the relationship of IL-18 with smoking and arterial hypertension, known risk factors implicated in atherogenesis. MATERIALS AND METHODS One hundred and thirty four men and 127 healthy women were included in the study. Plasma concentrations of IL-18 and leptin were determined in all subjects. Body composition was evaluated by bioelectrical impedanciometry. RESULTS IL-18 was distributed similarly in men and women and throughout decades. No significant differences were found in IL-18 between obese and normal-weight men and women according to their body mass index and body fat content. Higher IL-18 concentrations were found in subjects with arterial hypertension. In the bivariate correlation analysis only waist to hip ratio correlated weakly with IL-18 in the whole population (r=0.12, p=0.04). In the multiple regression analysis the relationship between IL-18 and waist to hip ratio lost significance after adjusting for age, sex and body mass index. However, IL-18 remained associated with arterial hypertension (adjusted r2=0.25, p=0.023). CONCLUSIONS The lack of correlation between IL-18 with anthropometric, body composition variables and leptin in our healthy population argues against a role of this cytokine in obesity. Moreover, our findings suggest the implication of this interleukin in the atherogenic process induced by arterial hypertension.
