This study aimed to determine the effects of sea buckthorn pulp oil treatment (800 mg/day for 60 days) on inflammatory, systemic oxidative/reductive status and endothelial function, in obese children. A total of 41 obese children (10–18 years old) and thirty controls were enrolled. The measurements were done before and after pulp oil administration. Ultrasounds were used for flow-mediated dilatation (FMD) and carotid artery intima-media thickness (IMT) measurements and colorimetric and ELISA methods for biochemical parameters. In the obese children versus the lean ones, increased oxidative stress (high malonyldialdehyde, high respiratory burst (RB)), low antioxidant defence (low blood glutathione, low TEAC), inflammatory status (high CRP, ceruloplasmin), adipocytokines disturbance (low adiponectin and high leptin), insulin resistance (high fasting C peptide), low FMD (P<0.001), and high IMT (P<0.01) were measured. Treatment reduced total cholesterol (P<0.03), triglycerides (P<0.01), RB (P<0.03), leptin (P<0.049), ceruloplasmin (P<0.01), fasting C peptide (P<0.01), blood pressure (P<0.01), and IMT (P<0.03). In conclusion, sea buckthorn pulp oil treatment prevents atherosclerosis by lowering triglyceridemia, cholesterolemia, and blood pressure (strong effects) and by reducing oxidative stress, inflammation, and insulin resistance (weak effects).

The aim of this study was to evaluate the relation between inflammatory markers and the preatherosclerotic marker - flow mediated dilation (FMD). Thirty obese children (10-16 years old) and twenty controls were involved. The plasma inflammatory markers: CRP, fibrinogen, leptin, TNF-a, IL-6 were measured. Ultrasounds were used for FMD measurement, chemiluminescence for monocyte respiratory burst (RB), ELISA for C peptide and spectrophotometry for usual parameters. In the obese children versus the lean ones, the FMD was lower (p[0.001), the plasma values for TNF-a were similar (1.68 pg/mL vs 1.54 pg/mL), while plasma IL-6 was increased (4.01 pg/mL vs. 2.02 pg/mL, p[0.05). These cytokines were negatively correlated with FMD (r=-0.42, p[0.05) and positively with RB (r=50, p[0.05). The FMD was negatively correlated (p[0.05) with the values for diastolic blood pressure (r = -0.47), waist circumference (r = -0.55), uric acid (r = -0.47) and atherosclerotic index (r = -0.37). In conclusion, in the obese children, inflammation, dyslipidaemia, blood pressure and oxidative stress act in a cluster reducing the elasticity of the vessel walls.

ObjectivePossibly due to a deficiency of insulin mediators, polycystic ovary syndrome (PCOS) is often associated with insulin resistance (IR) and hyperinsulinemia, likely responsible for an elevated production of reactive oxygen species. We investigated oxidative-related alterations in erythrocytes and anti-inflammatory effects of inositol in women with PCOS before and after treatment with myo-inositol (MYO).MethodsTwenty-six normal-weight PCOS patients were investigated before and after MYO administration (1200 mg/day for 12 weeks;n=18) or placebo (n=8) by evaluating serum testosterone, serum androstenedione, fasting serum insulin, fasting serum glucose, insulin area under the curve (AUC), and glucose AUC after oral glucose tolerance test and homeostasis model of assessment–IR. In erythrocytes, band 3 tyrosine phosphorylation (Tyr-P) level, glutathione (GSH) content, and glutathionylated proteins (GSSP) were also assessed.ResultsData show that PCOS patients' erythrocytes underwent oxidative stress as indicated by band 3 Tyr-P values, reduced cytosolic GSH content, and increased membrane protein glutathionylation. MYO treatment significantly improved metabolic and biochemical parameters. Significant reductions were found in IR and serum values of androstenedione and testosterone. A significant association between band 3 Tyr-P levels and insulin AUC was found at baseline but disappeared after MYO treatment, while a correlation between band 3 Tyr-P and testosterone levels was detected both before and after MYO treatment.ConclusionsPCOS patients suffer from a systemic inflammatory status that induces erythrocyte membrane alterations. Treatment with MYO is effective in reducing hormonal, metabolic, and oxidative abnormalities in PCOS patients by improving IR.

SummaryAdiponectin, which is secreted specifically from adipocyte, is thought to play a key role in the metabolic syndrome. We studied the associations of plasma adiponectin concentrations with blood cells and hepatopancreatic enzymes in 339 women aged 54.0 ± 0.8 (mean ± SE) years. Plasma adiponectin before and after adjustment for body composition or calculated insulin resistance increased in slight anemic women (372.6 ± 2.6 ×104/mm3) compared with non-anemic subjects (471.1 ± 1.7) (all p < 0.0001), and were inversely associated with red blood cells (RBC), hemoglobin, hematocrit, white blood cells and platelet values (p < 0.0001 ∼ 0.02), independent of age, diastolic blood pressure, body mass index, serum triglyceride, insulin resistance or blood urea nitrogen. Age and adiponectin/body fat mass (%) were negative, and blood pressure and insulin resistance were positive significant independent determinants of RBC in stepwise regression analysis. Moreover, adiponectin before and after adjustment were inversely associated with serum ALAT,γGTP and ChE, and positively with amylase levels (p < 0.0001 ∼ 0.02). These results indicate the possibility that increased adiponectin may contribute to the suppressive bone marrow function in vivo. Combined with the leptin’s data, adipocyte derived proteins were related to the hematopoiesis, therefore it has shown the possible existence of adipose tissue/ bone marrow function linkage more clearly. Furthermore, hepatopancreatic enzyme associations with this protein may indicate the possibility that adiponectin will regulate the hepatopancreatic function in health and disease.

Background: To investigate endothelial dysfunction and morphological vascular changes in childhood obesity. Methods: 93 overweight/obese children (body mass index 26 ± 5 kg/m2; median 26 kg/m2; interquartile range 22–28 kg/m2), mean age 10.9 ± 2.7 years, underwent a check-up of total, high-density lipoprotein- and low-density lipoprotein-cholesterol, triglycerides, C-reactive protein, erythrocyte sedimentation rate, and white blood cell count, together with ultrasound measures of flow-mediated dilatation, carotid intima-media thickness, and anterior-posterior diameter of the abdominal aorta. Results: The body mass index of overweight/obese children had a statistically significant linear relationship ( p < 0.05) with triglycerides, erythrocyte sedimentation rate, carotid intima-media thickness, anterior-posterior diameter of the abdominal aorta, and flow-mediated dilatation values. Conclusions: Overweight/obese children have an initial endothelial dysfunction and vascular damage, i.e., the first stage in the development of atherosclerosis.

Objective. This study aimed to determine the effects of melatonin on insulin resistance in obese patients with acanthosis nigricans (AN). Methods. A total of 17 obese patients with acanthosis nigricans were recruited in a 12-week pilot open trial. Insulin sensitivity, glucose metabolism, inflammatory factors, and other biochemical parameters before and after the administration of melatonin were measured. Results. After 12 weeks of treatment with melatonin (3 mg/day), homeostasis model assessment insulin resistance index (HOMA-IR) (8.99 ± 5.10 versus 7.77 ± 5.21, p<0.05) and fasting insulin (37.09 5 ± 20.26 μU/ml versus 32.10 ± 20.29 μU/ml, p<0.05) were significantly decreased. Matsuda index (2.82 ± 1.54 versus 3.74 ± 2.02, p<0.05) was significantly increased. There were also statistically significant declines in the AN scores of the neck and axilla, body weight, body mass index, body fat, visceral index, neck circumference, waist circumference, and inflammatory markers. Conclusions. It was concluded that melatonin could improve cutaneous symptoms in obese patients with acanthosis nigricans by improving insulin sensitivity and inflammatory status.

In obese children, hyperinsulinaemia induces adverse metabolic consequences related to the risk of cardiovascular and other disorders. Branched-chain amino acids (BCAA) and acylcarnitines (Carn), involved in amino acid (AA) degradation, were linked to obesity-associated insulin resistance, but these associations yet have not been studied longitudinally in obese children. We studied 80 obese children before and after a one-year lifestyle intervention programme inducing substantial weight loss >0.5 BMI standard deviation scores in 40 children and no weight loss in another 40 children. At baseline and after the 1-year intervention, we assessed insulin resistance (HOMA index), fasting glucose, HbA1c, 2 h glucose in an oral glucose tolerance test, AA, and Carn. BMI adjusted metabolite levels were associated with clinical markers at baseline and after intervention, and changes with the intervention period were evaluated. Only tyrosine was significantly associated with HOMA (p<0.05) at baseline and end and with change during the intervention (p<0.05). In contrast, ratios depicting BCAA metabolism were negatively associated with HOMA at baseline (p<0.05), but not in the longitudinal profiling. Stratified analysis revealed that the children with substantial weight loss drove this association. We conclude that tyrosine alterations in association with insulin resistance precede alteration in BCAA metabolism. This trial is registered with ClinicalTrials.gov IdentifierNCT00435734.

Abstract. Most studies concerning the influence of tacrolimus on glucose metabolism have been performed either in animals or after organ transplantation. These clinical studies have largely been transversal with patients who were using steroids. Therefore, this prospective, longitudinal study investigated the influence of tacrolimus on glucose metabolism before and after transplantation. Eighteen Caucasian dialysis patients underwent an intravenous glucose tolerance test before and 5 d after the start of tacrolimus. Insulin sensitivity index (kG), insulin resistance (insulin/glucose ratio and homeostasis model assessment), and C-peptide and insulin secretion were calculated. Trough levels of tacrolimus were measured. After transplantation, the occurrence of posttransplantation diabetes mellitus (PTDM) was prospectively monitored. Statistical analysis was performed using the Wilcoxon signed ranks test and Spearman's rho for correlation. Before tacrolimus, kG was indeterminate in three patients. During tacrolimus, kG decreased in 16 of 18 patients, from a median of 1.74 mmol/L per min to 1.08 mmol/L per min (P < 0.0001). The correlation between C-peptide and insulin data was excellent. Insulin secretion decreased from 851.0 mU × min/L to 558.0 mU × min/L (P = 0.014), whereas insulin resistance did not change. Insulin sensitivity correlated negatively with tacrolimus trough level. After transplantation, three patients developed PTDM; before tacrolimus, two had an indeterminate and one a low normal kG. During tacrolimus administration, kG decreased in almost all patients as a result of a diminished insulin secretion response to a glucose load, whereas insulin resistance did not change. Patients with an abnormal or indeterminate kG seem to be at risk of developing PTDM while on tacrolimus.

Introduction. The effects of fatty acids on health vary and depend on the type, amount, and route of consumption. EPA and DHA have a defined role in health, unlike coconut oil. Objective. The aim was to investigate the changes in metabolic regulation and the composition of the culture-dependent microbiota after supplementation with different fatty acids in db/db mice. Material and Methods. We were using 32 8-week-old db/db mice, supplemented for eight weeks with EPA/DHA derived from microalgae as well as coconut oil. The lipid, hormonal profiles, and composition of the culture-dependent microbiota and the phylogenetic analysis based on the 16S rRNA gene sequencing were determined for identification of the intestinal microbiota. Results. Enriched diet with EPA/DHA reduced TNF-α, C-peptide, insulin resistance, resistin, and the plasma atherogenic index, but increased TC, LDL-c, VLDL-c, and TG without changes in HDL-c. Coconut oil raised the HDL-c, GIP, and TNF-α, with TG, insulin resistance, adiponectin, and C-peptide reduced. Conclusion. The most abundant microbial populations were Firmicutes and the least Proteobacteria. EPA/DHA derived from microalgae contributes to improving the systemic inflammatory status, but depressed the diversity of the small intestine microbiota. Coconut oil only decreased the C-peptide, raising TNF-α, with an unfavorable hormonal and lipid profile.

The pathogenesis of essential hypertension through the interaction with elements of the rennin angiotensin aldosterone system is affected by oxidative stress and inflammation. The present study aimed to assess the effects of ACE-Inhibitor, lisinopril, on blood pressure, lipid profiles (total cholesterol, triglycerides, LDL and HDL), MDA, and TAS, hsCRP, and serum leptin levels n hypertensive patients. A case control study included 100 newly diagnosed mild to moderate hypertensive patients and another 100 apparently healthy aged and sex matched subjects as controls. The patients were treated with 10 mg lisinopril orally per day for three months’ duration. Venous blood sample was taken to test levels of MDA, GSH and TAS, hsCRP, lipid profiles and leptin in the serum before and after lisinopril therapy for both patients and controls. Systolic and diastolic blood pressure were also assessed before and after lisinopril therapy for both patients and controls. In hypertensive patients treated with lisinopril, markers of oxidative stress (MDA, TAS and GSH), high sensitive C-reactive protein and leptin were all found to be decreased significantly after drug treatment (p &lt; 0.01). Lisinopril affectively lowered systolic and diastolic BP values (p &lt; 0.01). A significant decrease in lipid profile (p &lt; 0.01) with a significant increase in HDL-C and TAS levels (p &lt; 0.01) were found in lisinopril treated group in comparison with their values before treatment. Lisinopril may be used as a treatment for high blood pressure, as well as for the insulin resistance, hyperleptinemic, and low-grade inflammatory states that are associated with the disease.
