Abdominal obesity has been linked to the development of insulin resistance and Type 2 diabetes mellitus (DM2). By surgical removal of visceral fat (VF) in a variety of rodent models, we prevented insulin resistance and glucose intolerance, establishing a cause-effect relationship between VF and the metabolic syndrome. To characterize the biological differences between visceral and peripheral fat depots, we obtained perirenal visceral (VF) and subcutaneous (SC) fat from 5 young rats. We extracted mRNA from the fat tissue and performed gene array hybridization using Affymetrix technology with a platform containing 9 000 genes. Out of the 1 660 genes that were expressed in fat tissue, 297 (17.9 %) genes show a two-fold or higher difference in their expression between the two tissues. We present the 20 genes whose expression is higher in VF fat (by 3 - 7 fold) and the 20 genes whose expression is higher in SC fat (by 3 - 150 fold), many of which are predominantly involved in glucose homeostasis, insulin action, and lipid metabolism. We confirmed the findings of gene array expression and quantified the changes in expression in VF of genes involved in insulin resistance (PPARgamma leptin) and its syndrome (angiotensinogen and plasminogen activating inhibitor-1, PAI-1) by real-time PCR (qRT-PCR) technology. Finally, we demonstrated increased expression of resistin in VF by around 12-fold and adiponectin by around 4-fold, peptides that were not part of the gene expression platform. These results indicate that visceral fat and subcutaneous fat are biologically distinct.

The medical community faces an emerging epidemic of type 2 diabetes mellitus (DM2) in children and adolescents with a disproportionate increase among certain ethnic groups. DM2 represents one arm of the metabolic syndrome and parallels an increasing prevalence of obesity. The metabolic syndrome includes insulin resistance, hyperlipidemia, and hypertension with a consequent risk of early cardiovascular disease. Thus, treatment of DM2 and the metabolic syndrome poses a challenge for pediatric endocrinologists and represents a huge public health issue. This review presents information about treatment of childhood DM2 with emphasis on indications for the use of insulin in management and normalization of blood glucose.

Prevalence of the Type 2 diabetes mellitus (DM2) has been rising in the whole word. It is assumed that before DM2 develops, patients undergo a stadium of impaired glucose tolerance (IGT) or they have impaired fasting glycaemia (IFG). The confirmed IFG or IGT represent strong predictors of DM2 manifestation and at the same time they are related with high cardiovascular risk, namely with IGT. Other significant risk factor (RF) of DM2 is the obesity and metabolic syndrome. Recent clinical studies have shown that some metabolic abnormalities, which precede development of DM2 can be positively influenced by the lifestyle changes, including improvement of the diet and increasing the physical activity. Such measures can prevent or at least to delay the development of type 2 diabetes mellitus and thus the development of cardiovascular diseases. Positive effect has also the administration of some drugs, already tested in clinical studies, namely glitasons, metromin, inhibitor of ACE, sartans and other.

Guidelines for the treatment of risk factors in diabetes care have been updated recently, due to indisputable results from clinical end-point trials. This study evaluates risk factor control compared with current national and international targets during the period 1996-2003 in Type 2 diabetes (DM2). Patients were registered in primary-care and hospital outpatient clinics using computer software, or via the Internet. The clinical characteristics of the patients, treatment, HbA(1c), and risk factors were reported after screening by local methods. The numbers of cases of DM2 reported were 17547 in 1996 and 57119 in 2003. The mean HbA(1c) decreased from 7.8 to 7.2%, while blood pressure decreased from 150/82 to 143/78 mmHg during the same period. Longitudinal analysis of results was performed in 5356 patients repeatedly reported, showing slightly lower effects. The new European treatment targets of HbA(1c)< or = 6.1%, blood pressure < 130/80 mmHg and total cholesterol < 4.5 mmol/l were attained by 16, 13 and 28% of the patients in 2003, respectively. The prevalence of the metabolic syndrome in 2003 was 77%. Aspirin was prescribed in 36% of cases. Lipid-lowering, anti-hypertensive drugs, and treatment with oral hypoglycaemic agents in combination with insulin were increasingly employed during the period studied. Risk factor control in DM2 reported to the National Diabetes Register (NDR) is slowly improving, although multiple risk factors and the metabolic syndrome are found in most patients. The majority of subjects do not achieve current target levels for HbA(1c), blood pressure and blood lipids. Thus, giving up smoking and increased use of aspirin are called for, as well as more aggressive treatment of hyperglycaemia, elevated blood pressure and blood lipid levels, in accordance with updated international guidelines.

Type II diabetes mellitus (DM2) is associated with an increased risk of cognitive dysfunction and dementia. The increased risk of dementia concerns both Alzheimer's disease and vascular dementia. Although some uncertainty remains into the exact pathogenesis, several mechanisms through which DM2 may affect the brain have now been identified. First, factors related to the 'metabolic syndrome', a cluster of metabolic and vascular risk factors (e.g. dyslipidaemia and hypertension) that is closely linked to DM2, may be involved. A number of these risk factors are predictors of cerebrovascular disease, accelerated cognitive decline and dementia. Secondly, hyperglycaemia may be involved, through adverse effects of potentially 'toxic' glucose metabolites on the brain and its vasculature. Thirdly, insulin itself may be involved. Insulin can directly modulate synaptic plasticity and learning and memory, and disturbances in insulin signalling pathways in the periphery and in the brain have recently been implicated in Alzheimer's disease and brain aging. Insulin also regulates the metabolism of beta-amyloid and tau, the building blocks of amyloid plaques and neurofibrillary tangles, the neuropathological hallmarks of Alzheimer's disease. In this paper, the evidence for the association between DM2 and dementia and for each of these underlying mechanisms will be reviewed, with emphasis on the role of insulin itself.

Alanine aminotransferase (ALT) is a marker of non-alcoholic fatty liver disease (NAFLD) and predicts incident type 2 diabetes mellitus (DM2). Recently, ALT was shown to be also associated with endothelial dysfunction and carotid atherosclerosis. We studied the predictive value of ALT for all-cause mortality, incident cardiovascular disease (CVD) and coronary heart disease (CHD) events in a population-based cohort of Caucasian men and women aged 50-75 years, at baseline. The 10-year risk of all-cause mortality, fatal and non-fatal CVD and CHD events in relation to ALT was assessed in 1439 subjects participating in the Hoorn Study, using Cox survival analysis. Subjects with prevalent CVD/CHD and missing data were excluded. As compared with the first tertile, the age- and sex-adjusted hazard ratios (95% confidence intervals) for all-cause mortality, CVD events and CHD events were 1.30 (0.92-1.83), 1.40 (1.09-1.81) and 2.04 (1.35-3.10), respectively, for subjects in the upper tertile of ALT. After adjustment for components of the metabolic syndrome and traditional risk factors, the association of ALT and CHD events remained significant for subjects in the third relative to those in the first tertile, with a hazard ratio of 1.88 (1.21-2.92) and 1.75 (1.12-2.73), respectively. In conclusion, the predictive value of ALT for coronary events, seems independent of traditional risk factors and the features of the metabolic syndrome in a population-based cohort. Further studies should confirm these findings and elucidate the pathophysiological mechanisms.

The aim was to compare in patients with type 2 diabetes mellitus (DM2) the prevalence of the metabolic syndrome according to the World Health Organization (WHO) and the National Cholesterol Education Program (NCEP) definitions, and to analyze the association between them and the complications of DM2. Patients with DM2 (n= 753) were evaluated for ethnics, anthropometrics and laboratory parameters and for the presence of DM2 complications: diabetic nephropathy, coronary artery disease, stroke, diabetic retinopathy and peripheral vascular disease. Insulin resistance was estimated using the HOMA index. Metabolic syndrome was found in 671 (89%) and 657 (87%) patients using the WHO definition and the NCEP definition, respectively. In the total group, there was a moderate agreement between the two definitions (k= 0.54; 95% CI 0.49-0.59), although, it was better for black patients (k= 0.69; 95% CI 0.60-0.78) than white (k= 0.54; 95% CI 0.48-0.6) or mulattos patients (k= 0.26; 95% CI 0.09-0.43). Patients with metabolic syndrome using the NCEP criteria had higher HOMA-IR values compared to those without metabolic syndrome (p= 0.001). This differentiation was not seen using the WHO definition (p= 0.152). The proportion of diabetic complications was similar for both definitions. In conclusion, regarding the risk of diabetic complications both definitions are equivalent. However, there are some ethnic differences in the agreement between the two definitions.

In the past years, in Brazil and in developed countries, obesity has become a major public health problem. It was identified that besides DM2 and metabolic syndrome other clinical entities were associated with insulin resistance. In this review we describe some of these alterations emphasizing nonalcoholic fatty liver disease, but also including polycistic ovary disease, hyperuricemia, chronic renal failure, heart failure, cognitive decline and cancer.

Metabolic syndrome (MS) is a risk condition for the development of systemic atherosclerotic disease. Morbid obesity is a state of insulin resistance (IR) associated with visceral fat accumulation, which is involved in the development of MS. In severe obesity, conservative therapies promote an improvement of MS, but weight regain is frequent, whereas bariatric surgery promotes a more significant and sustained weight loss. Bariatric surgery is recommended for patients with unsatisfactory response to clinical treatment and with IMC > 40 kg/m(2) or > 35 in case of co-morbidities. In those cases, surgical risk must be acceptable and patients submitted to surgery must be informed about complications and postoperative care. Prevention, improvement and reversion of diabetes (DM2) (70 to 90% of cases) are seen in several bariatric surgery modalities. Disabsorptive are more efficient than restrictive procedures in terms of weight reduction and insulin sensitivity improvement, but chronic complications, such as malnutrition, are also more frequent. Vertical gastroplasty with jejunoileal derivation is a mixed surgery in which the restrictive component predominates. In this modality, reversion of DM2 is due to an increase in insulin sensitivity associated with improved beta cell function. Reversion of MS and its manifestations after bariatric surgery are associated with reduction of cardiovascular mortality and, thus, in severe obesity cases, MS can be considered a surgical condition.

Studies have shown that hepatitis C (HCV) is associated with type 2 diabetes mellitus (DM2) possibly due to insulin resistance and inflammation. Metabolic syndrome is a risk factor for DM2. Our objectives were to assess the relationship between HCV and metabolic syndrome and inflammatory markers. We used data from The Third National Health Nutrition and Examination Survey (NHANES-III). We excluded pregnant women, subjects with diabetes, those taking non-steroidal anti-inflammatory drugs, and those diagnosed with concomitant infection. We analyzed the data controlling for demographic variables, body mass index, use of contraceptives, had arthritis, and had gout. Among the 10,383 subjects, 2.3% had HCV and 16.7% had metabolic syndrome using the ATP III criteria. After controlling for the confounders, HCV was not associated with metabolic syndrome but associated with HOMA insulin resistance and inflammatory marker ferritin. Among subjects with both HCV and metabolic syndrome, the adjusted HOMA insulin level was higher than those without HCV and metabolic syndrome. In addition, the serum ferritin level was a strong predictor of HOMA insulin resistance. In clinical practice, serum ferritin can be obtained along with routine blood tests in any laboratory, and it has a potential to be a surrogate marker of insulin resistance in people with HCV and metabolic syndrome.
