Unfortunately, all of these factors contribute to damage the endothelium that in turn, will conclude in the development of multiple complications observed in the metabolic syndrome. Endothelial dysfunction is mainly caused by a decrease in nitric oxide (NO) availability due to reduced NO production and/or increase in oxygen-derived free radicals (ROS) that can react with NO and inactivate the active molecule [2]. NO production in endothelial cells is mainly mediated by the endothelial isoform of NO synthase (eNOS), therefore, studies that investigate regulatory mechanisms of this enzyme are essential. Currently, the influence of metabolic syndrome on eNOS regulation is incompletely investigated. Recently, Guterbaum et al. [3] published a paper in this journal that describes the effects of H2O2 on phosphorylation of the eNOS of endothelial cells pretreated with supra-physiologic glucose concentrations. Their findings demonstrated that H2O2, with the concomitant increase ROS production, resulted in an increase in Thr495 phosphorylation while phosphorylation of Ser1177 was reduced. Furthermore, these authors demonstrated that combination of high glucose concentration with H2O2 induces phosphorylation of Thr495 through the PKC pathway. These phosphorylation sites confere fine regulation of eNOS activity [4] and the findings by Guterbaum et al. provide bases to understand more the complexity of pathophysiologic mechanisms that characterize the metabolic syndrome.","PeriodicalId":16452,"journal":{"name":"Journal of metabolic syndrome","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77724789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is necessary to optimize the treatment (dyslipidemia) of these patients. \u0000Methods: We examined changes in physiological parameters, renal function markers and lipid profiles induced by statins, such as pravastatin sodium (water-soluble, PS), atorvastatin calcium hydrate (fat-soluble, ACH) and pitavastatin calcium (fat-soluble, PC). \u0000Results: Dyslipidemia with medication was observed in 34 (24.8%) of the 137 HD patients. The therapeutic statins used for dyslipidemia were as follows: PS was used in the nine patients, ACH was used in 11 patients and PC was used in nine HD patients. The waist circumference and body mass index were more significantly increased in the patients treated with ACH (90.9 ± 10.5 cm [mean ± standard deviation], 24.8 ± 2.9 kg/m2) than in the patients treated with PS (79.9 ± 10.3 cm, 21.0 ± 2.9 kg/m2; P < 0.05). While the serum triglyceride levels in the PS group were 103 ± 36 mg/dl, those in the ACH group were 164 ± 75 mg/dl (P < 0.05). In addition, the serum whole parathyroid hormone levels were significantly higher in the ACH group (151 ± 102 pg/ml) than in the PS group (55 ± 32 pg/ml, P < 0.05). There were no differences between the PS and the PC groups in any of the laboratory data, except for the serum creatinine levels. \u0000Conclusion: Waist circumference, body mass index and the serum triglyceride levels were increased in the ACH HD patients. Interestingly, the serum whole PTH levels were found to be significant in the ESRD patients treated with ACH. Based on our results, PC may be an ideal statin for treating HD patients.","PeriodicalId":16452,"journal":{"name":"Journal of metabolic syndrome","volume":"79 12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83150505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comorbid axis I disorders and alcohol or substance use were excluded. NCEP ATP III formulated an operational definition of MetS based on the presence of three or more of the following characteristics: abdominal obesity (waist circumference), hypertriglyceridemia, low HDL or being on an antilipidemic agent, high blood pressure or being on an antihypertensive agent, and fasting hyperglycemia or being on antiglycemic agent. The patients who had been in remission period for at least 8 weeks were evaluated with SCIP-TURK and TEMPS-A. Remission was defined as YMRS score<5. \u0000Results: MetS was found to be more frequent in these patients than the patients who didn’t have a PDE. PDE, negative family history, childhood trauma and seasonality are determined as the predictors of MetS. Anxious temperament scores were higher in MetS (+) FME patients of both groups. Irritable temperament scores were higher only in MetS (+) FME patients without PDE group. \u0000Conclusion: The presence of MetS seems to be correlated with the onset and progression of BD.

Its abnormalities have been associated with early mortality, sudden death, silent myocardial infarction, gastrointestinal diseases. The manifestation of the ANS dysfunction in several human diseases is underestimated. Evidences exist on the important role of ANS dysfunctions in different clinically relevant conditions, including diabetes mellitus, chronic functional constipation, scleroderma, thalassemia major. Beside the classical evaluation in patients with diabetes mellitus, little is known about the effects of metabolic factors on ANS dysfunction. The metabolic syndrome (MetS) includes a cluster of frequent abnormalities (impaired fasting glycaemia, dyslipidemia, arterial hypertension and increased visceral adiposity) predisposing to the atherosclerotic changes and increased cardiovascular mortality. Early signs of autonomic dysfunction are often found in subjects with MetS even in the absence of diabetes. Epidemiological studies demonstrated that diabetics display a cardiovascular risk which is twice that of sex- and age-matched non-diabetic population. Manifestations of such a high cardiovascular risk of subjects with DM are the frequent silent myocardial infarctions (MI)s of diabetics which are often due to impaired cardiovascular autonomic function. Only recently major attention has been given to the interactions between impaired glucose tolerance (IGT) and cardiovascular autonomic dysfunctions. When increased waist circumference (one of the features of the MetS) and IGT are both present, cardiovascular autonomic dysfunction also occurs. Some adipokines (e.g. adiponectin) seem to play a role in cardiovascular risk and autonomic dysfunction. This review will therefore focus on some subtle aspects linking ANS dysfunction and MetS.","PeriodicalId":16452,"journal":{"name":"Journal of metabolic syndrome","volume":"40 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73812837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inhibition of carbonic anhydrase results in metabolic acidosis which leads to decrease in pH. \u0000Aim and objectives: The study aims to highlight the potential utility of erythrocyte carbonic anhydrase as therapeutic target for managing diabetes, by investigating changes of erythrocyte carbonic anhydrase activity in STZ induced diabetic rats. \u0000Methods: Carbonic anhydrase activity was determined by the absorbance of p-nitrophenol at 345nm released from p-nitrophenyl acetate. HbA1c was determined by ion exchange method (Spectrum diagnostics). Biochemical parameters were determined by Accutrend GCT meters with cobias® test strips. \u0000Results: The result revealed that inhibition of erythrocyte carbonic anhydrase results in significant increase in both blood lactate concentration and HbA1c level with significant reduction in blood glucose concentration. Metformin was found to reduce carbonic anhydrase activity and HbA1c level significantly and increased blood lactate concentration. The extract of Cadaba farinosa was found to reduce blood glucose concentration. \u0000Conclusions: Inhibition of carbonic anhydrase can be associated with reduced circulating blood glucose level. Metformin may therefore reduce circulating blood glucose by inhibiting carbonic anhydrase. Increased level of HbA1c may probably be due to inhibition of erythrocyte carbonic anhydrase. Therefore Carbonic anhydrase can potentially serve as a therapeutic target for managing diabetes in combination as serving as valuable marker for lactic acidosis.","PeriodicalId":16452,"journal":{"name":"Journal of metabolic syndrome","volume":"52 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87437241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
