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.

Overweight Or Obesity

Background Whether long‐term exposure to overweight or obesity from early life to adulthood has a detrimental influence on health outcomes is unknown. We aimed to investigate whether duration of overweight or obesity from youth to adulthood is associated with adult cardiometabolic risk. Methods and Results A population‐based cohort study was performed of 1268 youths, aged 3 to 18 years, with follow‐ups at 3, 6, 9, 12, 21, 27, and 31 years. Duration of overweight or obesity over 31‐year follow‐up was calculated. Adulthood outcomes included type 2 diabetes mellitus, impaired fasting glucose, high insulin levels, high carotid intima‐media thickness, hypertension, low high‐density lipoprotein cholesterol, high low‐density lipoprotein cholesterol and triglycerides, arterial pulse wave velocity, carotid artery compliance, Young elastic modulus, and stiffness index. Rates of overweight/obesity were 7.9% at baseline and 55.9% after 31 years. After adjustment for confounders, longer duration of overweight or obesity was associated with increased risk of all outcomes (relative risk ranged from 1.45–9.06 for type 2 diabetes mellitus, impaired fasting glucose, carotid intima‐media thickness, hypertension, high‐density lipoprotein cholesterol, low‐density lipoprotein cholesterol, and triglycerides; β from 0.370–0.543 m/s for pulse wave velocity; –0.193 to –0.237 %/10 mm Hg for carotid artery compliance; 52.1–136.8 mm Hg·mm for Young elastic modulus; and 0.554–0.882 for stiffness index). When body mass index was further adjusted, these associations disappeared or were substantially reduced. Detrimental associations of adult body mass index with all outcomes were robust to adjustment for confounders and duration of overweight or obesity. Conclusions Overweight or obesity in adulthood rather than childhood appears to be more important for adult cardiometabolic health.

AbstractBackground:The aim of this study was to investigate the early signs of atherosclerosis and to evaluate serum endoglin and obestatin levels as predictors of subclinical atherosclerosis in obese children.Methods:A total of 95 children (60 obese and 35 controls) aged 10–18 years were included in the study. Their endoglin and obestatin levels and biochemical parameters were measured. The carotid intima media thickness (cIMT) and brachial artery flow-mediated dilatation (FMD) responses were evaluated.Results:The cIMT values were higher (p < 0.001) and FMD responses were lower (p = 0.003) in the obese group than in the control group. A logistic regression multivariate analysis revealed that cIMT was independently associated with the body mass index (BMI) Z-score (β = 0.323, p = 0.003) and low density lipoprotein (LDL) (β = 0.29, p = 0.008), while FMD % was independently associated with waist circumference (β = −0.36, p = 0.002). The obese and control groups were similar in endoglin (p = 0.67) and obestatin levels (p = 0.70). The endoglin level was inversely correlated with the cholesterol and LDL levels (r = −0.23, p = 0.032; rho = −0.25, p = 0.019).Conclusions:The cIMT and brachial artery FMD response in obese children are significantly different compared to healthy controls. Circulating endoglin and obestatin levels are not predictive markers for subclinical atherosclerosis in obese children aged 10–18 years old.

Migraine Pathophysiology

Background: Endothelial dysfunction could be involved in the pathophysiology of migraine. The results obtained from a few studies on endothelial dysfunction in migraine are controversial. We investigated brachial flow-mediated dilatation (FMD), which reflects systemic endothelial dysfunction, in migraine patients without comorbidities. By employing strict inclusion criteria we avoided the possible changes to FMD from confounding factors. Methods. Forty migraine patients without comorbidities (20 with and 20 without aura) and 20 healthy subjects were included. FMD of brachial arteries and carotid intima-media thickness were measured by using standard procedures. Results. We did not find any difference in FMD between migraine patients and healthy subjects ( p = .96). Also, no differences were found among healthy subjects, migraine patients with aura and without aura ( p = .99). Conclusion. Our study showed that systemic endothelial function is not impaired in migraine patients without comorbidities, neither in those with or without aura. Considering these findings, the investigation of cerebral endothelial function would be useful in a further investigation of the role of endothelial (dys)function in migraine pathophysiology.

Objectives We compared carotid intima media thickness (CIMT) and flow-mediated dilatation (FMD) between cases [end-stage renal disease patients (diabetic and nondiabetic) on peritoneal dialysis (PD)] and controls (diabetic and hypertensive patients with normal renal function) with the objective of identifying risk factors predicting atherosclerosis. Methods This cross-sectional study involved 124 subjects (62 cases, 62 controls). In both the case and control populations, we used B-mode ultrasonography to study CIMT and endothelium-dependent FMD, according to American College of Cardiology guidelines on brachial artery measurement. Pearson correlation was used to evaluate the correlation between CIMT and other variables. Results Compared with controls, cases had significantly higher systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, triglycerides, serum uric acid, inorganic phosphate, C-reactive protein, and parathyroid hormone, and significantly lower hemoglobin, calcium, and high-density lipoprotein. Compared with controls, cases showed significantly greater CIMT (0.60 ± 0.08 mm vs 0.54 ± 0.03 mm, p < 0.001) and significantly lower FMD (0.15 ± 0.08 cm vs 0.21 ± 0.04 cm, p = 0.02). Among cases, patients with diabetes had significantly greater CIMT (0.62 ± 0.08 mm vs 0.58 ± 0.07 mm, p = 0.05) than did patients without diabetes; FMD was similar in diabetic and nondiabetic patients on continuous ambulatory PD (0.16 ± 0.03 cm vs 0.18 ± 0.03 cm, p = 0.20). Conclusions Compared with controls, cases had significantly higher CIMT and lower FMD. Cases with diabetes had significantly higher CIMT than did cases without diabetes, but FMD was similar in diabetic and nondiabetic cases. Serum inorganic phosphate is an independent risk factor for atherosclerosis and was significantly correlated with CIMT. The noninvasive CIMT and FMD tests can be used to monitor atherosclerosis and endothelial dysfunction.

Background. The study was designed to assess cardiovascular risk factors flow-mediated dilatation % (FMD%) and carotid intima-media thickness (CIMT) in NAFLD. Methods. 126 NAFLD subjects and 31 chronic hepatitis B (CHB) controls were studied. Measuring carotid intima-media thickness (CIMT) and the flow-mediated dilatation % (FMD%) by brachial artery Doppler ultrasound were used to assess atherosclerosis. The risk of cardiac events at 10 years (ROCE 10) was estimated by the Prospective Cardiovascular Munster Study (PROCAM) score. Results. 58 of 126 NAFLD have coexistent metabolic syndrome. Mean CIMT was 0.73±0.041 mm among NAFLD with MS, 0.66±0.016 mm among NAFLD without MS, and 0.66±0.037 in controls CHB patients. FMD% in NAFLD with MS was 10.43±3.134%, but was 8.56±3.581% in NAFLD without MS and 17.78±6.051% in controls. PROCAM score of NAFLD with MS was 46.95±6.509 while in NAFLD without MS was 38.2±3.738. Controls had a PROCAM score of 38.13±5.755. ROCE 10 in NAFLD with MS was 13.64±8.568 while NAFLD without MS was 5.55±1.949. Controls have a ROCE 10 of 5.95±3.973. Post hoc analysis showed CIMT was dependent upon MS while FMD% was different between all subgroups hence independent of metabolic syndrome. Conclusion. The markers of endothelial dysfunction are significantly higher in patients with NAFLD than controls.

AbstractWe aimed to evaluate the association between hyperlipidemia and carotid intima media thickness in obese children, compared to non-obese ones.Two hundred (110 girls, 90 boys) children aged between 6 and 15 years participated in this study. The obese group included 53 girls, 47 boys whose body mass indices (BMI) above 95th percentile, the control group included 57 girls, 43 boys who had normal weight. Fasting total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) levels were measured. Carotid intima media thickness (cIMT) was performed with neck ultrasound.The median thickness of right, left and mean carotis intima media were statistically higher in the study group, compared to the control group. The mean cholesterol, triglyceride, HDL-C, LDL-C levels of the study group were statistically higher, compared to the control group. There was no relationship between BMI and left carotis intima media thickness, but there was statistically significant relationship between BMI and right, mean cIMTs in the study group. There was no correlation between serum lipid levels and cIMTs in the study group. The mean atherogenic index of the study group was statistically higher, compared to the control group. There was no statistical correlation between atherogenic index and cIMTs in both of the groups.We observed that obese children had higher carotis intima media thicknesses. Carotis intima media thickness related to obesity can play an important role in future pre-atherosclerotic changes. Large population based studies are required to confirm this associaton.

: Vascular diseases are the main reason for morbidity and mortality worldwide. As we know, the earlier phase of vascular diseases is endothelial dysfunction in humans, the endothelial tissues play an important role in inflammation, coagulation, and angiogenesis, via organizing ligand-receptor associations and the various mediators’ secretion. We can use many inflammatory non-invasive tests (flowmediated dilatation, epicedial fat thickness, carotid-intima media thickness, arterial stiffness and anklebrachial index) for assessing the endothelial function. In addition, many biomarkers (ischemia modified albumin, pentraxin-3, E-selectin, angiopoietin, endothelial cell specific molecule 1, asymmetrical dimethylarginine, von Willebrand factor, endothelial microparticles and endothelial progenitor cells) can be used to evaluate endothelial dysfunction. We have focused on the relationship between endothelial dysfunction and inflammatory markers of vascular disease in this review.

Background:The aim of this study is to investigate, evaluation of monocyte to high density liporotein ratio and carotid intima media thickness in gout patients.Objectives:Gout disease is an autoinflammatory disease caused by the accumulation of monosodium urate crystals (MSU) in tissues and organs due to hyperuricemia (1). It is a common cause of arthritis due to the changes in lifestyle and eating habits. The effects of the inflammatory process and hyperuricemia in gout are not limited to the joints, but are associated with increased atherosclerosis and cardiovascular disease (1,2) Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a systemic inflammatory marker and has recently been used quite widely for the evaluation of inflammation in cardiovascular disorders (3,4).Methods:Fourty eight patients who were evaluated in the rheumatology clinic with an arthritis attack and diagnosed with Gout, and 48 healthy individuals whose age, gender and body mass index were matched were included in our study. Basic laboratory and biochemical parameters of the period when gout patients were asymptomatic were examined. Carotid intima-media thickness (CIMT), which is a non-invasive procedure due to its widespread use, was used as a marker.Results:MHR and CIMT values were 18.22 ± 9.01 and 0.76 ± 0.11 mm in patients with gout. In the control group, it was 13.62 ± 4.48 and 0.65 ± 0.13 (p = 0.002, p <0.0001, respectively). When evaluated within the study group, it was found that there was a positive correlation between MHR and CIMT (r = 0.253, p = 0.013), and according to linear regression analysis, there was an independent relationship between MHR and CIMT (beta [β] = 0.293, p = 0.049). When assessing Gout patients in the study population, a cutoff value of 13.85 with sensitivity of 66 %, specificity of 53 %, and p = 0.011 (area under curve: 0.650, 95% confidence interval 0.540-0.760), was observed according to receiver-operating characteristic curve analysis (Figure 1).Figure 1.Receiver-operating characteristic curve analysis.Conclusion:This study showed us that MHR can be an inexpensive and easily accessible marker that can be used in the evaluation of atherosclerotic lesions. We think that studies with larger number of patients are needed on this subject.References:[1]Çukurova S, Pamuk ON, Unlu Ercument, Pamuk GE, Cakir NE.
