The aim. Assessment of the relationship between the occurrence of endotoxemia and impaired resorption function of the small intestine, arrhythmia of the motility of the stomach and intestines, and excessive bacterial growth in the metabolic syndrome (MS).Materials and methods. 62 patients with MS were examined. The average age was 48.62+3.75 years. The motor function of the gastrointestinal tract was studied using peripheral electrogastroenterocolography. To assess the absorption processes in the small intestine, stress tests with glucose and d-xylose were used. Blood endotoxin level, quantitative and& qualitative composition of parietal microbiota of small intestine were determined using an Agilent gas chromatograph with mass-selective and flame-ionization detectors (Agilent Technologies, USA).Results. 82.9% of the examined patients with MS showed clinical signs of intestinal damage. The electrical activity of& the& small intestine departments in the postprandial period was low in 70% of patients. The electrical activity of& the& colon on an empty stomach was not changed, and after a food load was reduced. Discoordination of motility is observed between small intestine and the colon, aggravated after food stimulation. A significant decrease in the rhythm of contractions is observed at the frequencies of the jejunum, ileum, and colon both on an empty stomach and in the postprandial period, which indicates a weakening of propulsive bowel contractions in patients with MS. In patients with MS, an increase in& the& absorption of glucose and d-xylose was revealed in comparison with the group of healthy individuals. In patients with MS, excessive bacterial growth in small intestine is observed mainly due to conditionally pathogenic microbiota strains. According to the results of the study of blood endotoxin level in patients with MS, a significant increase was revealed in comparison with the control group. Correlation analysis showed a moderate negative relationship between the level of endotoxin and electrical activity of small intestine, between the level of endotoxin and the ratio of the ratio of& the& colon to the ileum. A moderate positive relationship was established between the degree of endotoxemia increase and glucose absorption in small intestine.Conclusion. A study of the level of endotoxin and indicators of excessive bacterial growth, motor evacuation and resorption functions of small intestine revealed important pathogenetic patterns regarding the contributing role of the latter in& the development of endotoxemia in patients with MS.

Aim. To evaluate the qualitative and quantitative composition of the parietal microbiota of the small intestine (SI) and its significance in the disturbance of the digestive and absorption functions of the small intestine in metabolic syndrome (MS). Materials and methods. 67 patients with metabolic syndrome were examined. In addition to clinical data, a comprehensive study of the digestive and absorption function of SI was carried out using exercise tests with carbohydrates. The compositional characteristics of mucosal SI microbiota in MS patients were determined by gas chromatography mass spectrometry. The relationship of enteric disorders with changes in small intestinal microbiocenosis was assessed by correlation analysis. Results. The majority (82.9%) of patients with metabolic syndrome showed clinical local and general signs of small intestinal lesions. Violations of all stages of the hydrolysis - resorption process were revealed against the background of changes in the quantitative and qualitative composition of the parietal microbiota of the small intestine. In patients with MS, excessive bacterial growth is observed in the small intestine mainly due to conditionally pathogenic microbiota strains, and, in comparison with the control group, there is a significant increase in the growth of aerobes, microscopic fungi and viruses. The relationship between the severity of excess bacterial growth and impaired digestion and absorption in the small intestine in MS. Conclusion. The results of our research suggest that the identified changes in the functional state of SI in combination with a violation of mucosal enteral microbiocenosis are an important link in the complex pathogenesis of the MS.

Background: The metabolic syndrome is a constellation of cardiometabolic risk factors that tend to cluster together in affected individuals more often than predicted by chance. The presence of the metabolic syndrome substantially increases the risk of developing type 2 diabetes and cardiovascular disease, and is associated with a range of adverse clinical outcomes, many of which are closely associated with aging. Current estimates suggest that approximately 20 - 25% of the world’s population is affected by the metabolic syndrome. The prevalence of the metabolic syndrome rises with age and more than 45% of people aged over 60 years have the metabolic syndrome. Recent studies show that low vitamin D status is very common in the world and this is a risk factor of metabolic syndrome. Objective: (1) Plasma 25-hydroxyvitamin D concentration in subjects with metabolic syndrome. (2) Cut off value of plasma 25-hydroxyvitamin D concentration for predicting metabolic syndrome. Material and method: A cross-sectional study with control group on 318 adult subjects for health examinations at International Medical Center at Hue Central Hospital, including 139 subjects with metabolic syndrome and control group of 179 healthy subjects. Metabolic syndrome was defined according to the IDF, NHLBI, AHA, WHF, IAS, IASO (2009). Plasma hydroxyvitamin D concentration was measured using chemiluminescent microparticle immunoassay. Reciever operating characteristic (ROC) curve were generated to assess sensitivity and specificity for different cut off value of 25-hydroxyvitamin D concentration for predicting metabolic syndrome. Results: Plasma 25-hydroxyvitamin D concentration in subjects with metabolic syndrome was 26.4 ng/ml, incidence of plasma 25-hydroxyvitamin D deficiency (59.7%) was significantly higher than in control group (23.5%) (p < 0.001). The optimal cut off point for 25-OH-D concentration for predictor of metabolic syndrome as 26.4 ng/ml (AUC=0.657, sensitivity=53.4%, specificity=71.6%). Conclusion: In 139 subjects with metabolic syndrome, the plasma 25-hydroxyvitamin D concentration was 26.4 ng/ml and the incidence of 25-hydroxyvitamin D deficiency in the metabolic syndrome group was 59.7%. The optimal cut off point for plasma 25-hydroxyvitamin D concentration for predictor of metabolic syndrome as 26.4 ng/ml. Key words: Metabolic syndrome, 25-hydroxyvitamin D

The Metabolic Syndrome

Modification of lifestyle, including healthy nutrition, is the primary approach for metabolic syndrome (MetS) therapy. The aim of this study was to estimate how individual nutrition intervention affects the reduction of MetS components. Subjects diagnosed with MetS were recruited in the Lomza Medical Centre. The study group consisted of 90 participants and was divided into one intervention group (individual nutrition education group (INEG)) and one control group (CG). The research was conducted over 3 months. The following measurements were obtained during the first visit and after completion of the 3 months intervention: body mass, waist circumference, body composition, blood pressure, fasting glucose, and blood lipids. Dietary assessments were performed before and post-intervention using 3-day 24-h dietary recalls. Dietary knowledge was evaluated with the KomPAN questionnaire. The total polyphenol content of the diet was calculated. Sociodemographic and lifestyle characteristics were collected from a self-reported questionnaire. The physical activity was assessed by the short version of the International Physical Activity Questionnaire (IPAQ). It was found that the individual nutrition education was an effective method to improve the knowledge, dietary habits, and physical activity of the study participants. The modification of the diet in terms of higher intake of polyphenols (flavonoids and anthocyanins), fiber, polyunsaturated fatty acids (PUFA), PUFA n-3, and lower intake of saturated fatty acids (SFA) had a significant impact on the improvement of some MetS risk factors (waist circumference, fasting glucose, and HDL-cholesterol).

Objective: To determine the syndrome of excessive bacterial growth in the small intestine (SIBO) in patients with insufficiency of the bauhinia valve (NBZ) and after its surgical correction. Methods of examination: Patients of the studied groups were examined using direct and indirect methods of diagnosis of SIBO. Bacteriological examination of ileal aspirate and other surgical material was performed. All patients underwent a hydrogen respiratory test with a load of lactulose and performed a qualitative reaction of urine to indican. Characteristics of the material: 50 patients were examined, of which 30 were included in the main group, who underwent surgical correction of NBZ - Bauginoplasty; 20 patients are included in the control group in which the ileocecal valve is consistent. Patients of the main group were examined before surgery and on the 7th and 45th day after Bauhinoplasty. Main results: All patients of the main group had SIBS of varying severity, in 80% of patients SIBS was localized in the distal small intestine. Patients with normal function of ileocecal valve syndrome of excessive bacterial growth did not suffer. Intraoperatively, 76% of patients showed signs of mesenteric mesentery of the small intestine, and the fact of bacterial translocation in SIBO was also confirmed. After 7 days after surgical correction of the Bauhinia valve, the normalization of peak and background excretion of hydrogen was observed in 37% of patients. For 45 days in all patients the hydrogen curve corresponded to the norm. Conclusions: the deficiency of the bauhinia valve is obligately accompanied by the syndrome of excessive bacterial growth in the small intestine, surgical correction is an effective method for correcting the syndrome of excessive bacterial growth in patients with NBD.

The Relationship

In this study, it was aimed to investigate the relationship between the epicardial adipose tissue thickness (EATT) and serum IL-17A level insulin resistance in metabolic syndrome patients. This study enrolled a total of 160 subjects, of whom 80 were consecutive patients who applied to our outpatient clinic and were diagnosed with metabolic syndrome, and the other 80 were consecutive patients who were part of the control group with similar age and demographics in whom the metabolic syndrome was excluded. The metabolic syndrome diagnosis was made according to International Diabetes Federation (IDF)-2005 criteria. EATT was measured with transthoracic echocardiography (TTE) in the subjects. IL-17A serum levels were determined using the ELISA method. Fasting blood glucose, HDL, triglyceride, and fasting insulin levels were significantly higher in the metabolic syndrome group compared to the control group. In addition, the metabolic syndrome group had significantly higher high-sensitivity C-reactive protein (hs-CRP) and Homeostatic Model Assessment Insulin Resistance (HOMA-IR) levels than the control group. Similarly, serum IL-17A levels were significantly elevated in the metabolic syndrome group compared to the control group statistically (p < 0.001). As well, EATT was higher in the metabolic syndrome than the control group. Conclusion: By virtue of their proinflammatory properties, EATT and IL-17 may play an important role in the pathogenesis of the metabolic syndrome.

Abstract Context: Diabetes and obesity, components of the metabolic syndrome, are common characteristics of women with prior gestational diabetes mellitus (GDM). Due to increasing incidence of diabetes and obesity, the metabolic syndrome might comprise a major health problem among these women. Objective: The objective was to estimate the prevalence of the metabolic syndrome by three different criteria [World Health Organization 1999 (WHO), The National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults 2001, and European Group for the Study of Insulin Resistance 2002] among women with previous GDM. Design: We conducted a follow-up study of a Danish cohort of women admitted in 1978–1996 to the Diabetes and Pregnancy Center, Rigshospitalet, Copenhagen University Hospital, with diet-treated GDM. The follow-up took place in 2000–2002 at median 9.8 yr (interquartile range 6.4–17.2) after pregnancy. Results were compared with a control group of 1000 age-matched women from a population-based sample (Inter99). Participants: Four hundred eighty-one women at median age 43 yr (interquartile range 38–48) participated. Main Outcome Measures: The main outcome measures were body mass index (BMI), glucose tolerance, blood pressure, lipid profile, and insulin resistance. Results: Independent of the criteria, the prevalence of the metabolic syndrome was three times higher in the prior GDM group, compared with the control group (e.g. WHO: 38.4 vs. 13.4%, P &lt; 0.0005). Age- and BMI-adjusted odds ratio for having the WHO-defined metabolic syndrome was 3.4 (95% confidence interval 2.5–4.8) for the prior GDM group vs. the control group. Obese women (BMI &gt; 30 kg/m2) with previous GDM had a more than 7-fold increased prevalence of the metabolic syndrome (WHO), compared with normal-weight prior GDM women (BMI &lt; 25 kg/m2). In glucose-tolerant women, the prevalence was doubled in the prior GDM group, compared with control group. Conclusion: The prevalence of the metabolic syndrome was three times as high in women with prior diet-treated GDM, compared with age-matched control subjects.

The aim of the present study was to verify the effects of fish oil and a soya-based product on inflammatory markers and endothelial function measured by NO in women with the metabolic syndrome (MetS). A total of sixty-five women (mean age: 47·9 (sd9·98) years) were studied in a 90-d parallel, randomised design. A control group maintained their usual diet; the second group received 29 g/d of soyabean (kinako); the third group received 3 g/d of fish oiln-3 fatty acids; and the fourth group received fish oil (3 g/d) and kinako (29 g/d). Anthropometric, blood pressure (BP), inflammatory markers, anti-inflammatory marker (adiponectin) and NO concentrations were evaluated. In relation to the baseline values, the group that received fish oil and kinako concomitantly presented a statistically significant decrease in systolic BP (SBP;P < 0·05), whereas there was a significant decrease in diastolic BP (DBP) in the control group (P < 0·05), kinako group (P < 0·01) and fish oil group (P < 0·01) after 90 d. There was a significant increase in adiponectin (P < 0·01) and NO values (P < 0·05) after 90 d in the kinako and fish oil groups. Differences between treatment groups verified a significant decrease (P < 0·05) in DBP in the kinako group after 90 d when compared to the results obtained from the fish oil and kinako groups. In conclusion, the findings of increased serum adiponectin and NO metabolite levels after 90 d, both in the fish oil and soya groups, reinforce the importance of the influence of adiponectin and NO levels on BP decrease in patients with the MetS.

Objectives It has been proposed that zinc-α2-glycoprotein and S100A1 are possibly linked to the development of lipogenesis and obesity. We aimed to measure serum levels of S100A1 and zinc-α2-glycoprotein in patients with metabolic syndrome and investigate any associations of these two novel peptides with each other or components of metabolic syndrome. Methods Forty-four patients with metabolic syndrome and the equivalent number of healthy controls participated in this study. The participants’ body mass index, waist circumference, systolic and diastolic blood pressure were measured. Serum levels of low- and high-density lipoprotein cholesterol, total cholesterol, triglyceride, fasting blood sugar, insulin, zinc-α2-glycoprotein and S100A1 protein were determined. Results Higher levels of anthropometric and lipid indices, metabolic factors and also SBP and DBP were observed in the metabolic syndrome group. Serum S100A1 levels were significantly lower in the metabolic syndrome group than the control group ( P = 0.008). There was a strong positive correlation between serum zinc-α2-glycoprotein and S100A1 levels ( r = 0.80, P < 0.0001). Serum levels of both S100A1 ( P = 0.03) and zinc-α2-glycoprotein ( P = 0.02) were potentially higher in subjects with hypertension than those with normal blood pressure, though these were found as part of multiple testing. Conclusion The results indicate that changes in the circulating level of S100A1 protein occur in metabolic syndrome patients. The strong correlation between serum zinc-α2-glycoprotein and S100A1 might suggest that production or release of these two proteins could be related mechanistically.

The aim of the study – to learn the dynamics of changes of morphometric, instrumental and laboratory parameters in mature females rats with experimental metabolic syndrome. Material and Methods. 20 females of white, mature laboratory rats, aged 18–20 months were divided into 2 groups. The first one is an experimental group: 13 female rats with experimental metabolic syndrome; the second one  – control group: 7 intact rats, with standard food and water regime. When working with animals, the standards of the Council of Europe Bioethics Convention 1997, the European Convention for the Protection of Vertebrate Animals were observed. Instruments used during scientific research were subject to metrological control. The simulation of the metabolic syndrome occurred during 60 days. The females supported a special high-calorie diet (grain with margarine 82 % milk fat, corn and sunflower seeds). The water regime included a 20 % solution of fructose and regular water ad libitum, with change every other day. Also, during the first and the fourth weeks of the experiment, the female daily subcutaneously administered Dexamethasone solution at a dosage of 0.1 mg/kg. Results. Since the beginning of the experiment, female rats who received a special high-calorie diet showed a statistically significant increase in all morphometric and instrumental indexes compared to similar rats in the control group. An increase in body weight in the experimental group was found to be 28.93 % higher than the original weight, was observed arterial hypertension (141/85±5) mmHg, dyslipidemia: elevated total cholesterol (5.37±0.33) mmol/L and TG (2.55±0.24) mmol/L; elevated level glucose (8.52±0.17) mmol/L. The above indicators are criteria indicating the presence of metabolic syndrome in animals under study. Conclusions. The proposed model of experimental metabolic syndrome, which includes subcutaneous administration of Dexamethasone solution at a dosage of 0.1 mg/kg in the first and the fourth weeks of experiment, with a special high calorie diet and a 20 % solution of fructose, is an effective way to reproduce the metabolic syndrome in small rodents.

Abstract Background: Acute pancreatitis (AP) is a common inflammatory disorder of pancreas. Recent evidence has shown that metabolic syndrome was positively correlated with the severity of AP. However, only few studies have revealed the relationship between metabolic syndrome and the occurrence of AP. We therefore elucidated the association between the metabolic syndrome components and the incidence rate of AP. Methods: A hospital-based case-control study was conducted. 705 patients admitted to our hospital from January 2016 to December 2018 were included in the study. Subjects were divided into case and control group according to their diagnosis: (1) According to the revised Atlanta classification from 2012, patients diagnosed as AP were enrolled into case group. (2) Patients without history of AP or any disease related to metabolic syndrome were allocated into control group. Controls were matched to cases individually by sex and age (control/case ratio=1). Risk factors were determined by univariate and multivariate logistic regression analyses. Results: The incidence rate of metabolic syndrome with AP patients was 30.9%, which was more frequent than controls (13.2%) (OR=2.975; 95%CI 1.947-4.548, p<0.001). In multivariate regression analysis, histories of smoking or alcohol drinking, biliary stone were important predictors of AP. Besides, occurrence of AP was significantly associated with total cholesterol (TC) (OR=1.831; 95%CI 1.137-2.948, p=0.013), triglyceride (TG) (OR=2.058; 95%CI 1.332-3.179, p=0.001), fasting plasma glucose (FPG) (OR =2.345; 95%CI 1.395-3.940, p=0.001), as well as low values of apolipoprotein A (Apo A) (OR =0.247; 95%CI 0.146-0.416, p<0.001). Conclusion: Metabolic syndrome and its components portend high risks of occurrence of AP.
