Previous studies have suggested that the daidzein metabolite equol rather than daidzein itself contributes to the beneficial effect of soya foods in the prevention of CVD. The aim of the present study is to examine the proportion of equol excretion in Chinese adults and compare plasma lipids and carotid artery intima–media thickness (IMT) between equol excretors and non-excretors, and to evaluate the effect of soya isoflavone intakes on serum lipids and IMT in either equol excretors or non-excretors. Subjects (n 572; women n 362, men n 210) were recruited for the present study. An overnight urine sample was provided by each subject on their usual diet to quantify urinary concentrations of daidzein and equol. Far-wall IMT was determined by B-mode ultrasound in the right carotid at two sites, carotid bulb (CB-IMT) and common carotid artery (CCA-IMT), and fasting serum lipids were measured. Habitual dietary intakes were estimated with a FFQ, and soya isoflavone intake derived from the FFQ was assessed. Of the 572 subjects, the proportion of equol excretors on their usual diet was 25·0 % (n 143). Compared with non-excretors, equol excretors showed significantly lower serum TAG ( − 38·2 (95 % CI − 70·4, − 5·9) %, P = 0·012) and CCA-IMT ( − 4·9 (95 % CI − 9·7, − 0·3) %, P = 0·033). Equol excretors with higher daily isoflavone intakes ( − 5·4 mg/d) had significantly lower IMT ( − 16·2 %, P = 0·035) and tended to have higher HDL-cholesterol (P = 0·055) than did those with lower daily isoflavone intakes (1·5 mg/d), while no association was observed between soya isoflavone intakes and serum lipids or IMT in non-excretors. In conclusion, the benefits of soya isoflavones in preventing CVD may be apparent among equol excretors only.

Abstract. Background: Carotid intima-media thickness (CIMT), an ultrasonographic marker of cardiovascular risk, is increasingly used in adults and children. The choice of specific images used to quantify CIMT from a cine sequence is often based on image quality rather than on a consistent point in the cardiac cycle. This methodological study quantified the imprecision that may be introduced by variation of CIMT during the cardiac cycle. Probands and methods: Data from four-year-olds, 11 to 12-year-olds, and adults (n=30 each age group) were selected retrospectively from two population-derived studies. Far wall CIMT of the right common carotid artery was measured at end-diastole and peak systole using standardized protocols. All images were analysed using semi-automated edge-detection software. Results: In all age groups CIMT varied significantly during the cardiac cycle and was largest at end-diastole. The mean difference in CIMT between end-diastole and peak systole was greater in four-year-olds (38 μm; 95 % confidence interval (CI) 33 to 43 μm) and 11 to 12-year-olds (31 μm; CI 26 to 36 μm) than in adults (18 μm; CI 16 to 22 μm). Carotid IMT increased by 8.8 % (CI 7.7 to 9.8 %), 6.9 % (CI 5.8 to 8.1 %), and 3.8 % (CI 3.1 to 4.5 %) between minimum and maximum arterial diameter in four-year-olds, 11 to 12-year-olds, and adults, respectively. The greatest variation in CIMT during the cardiac cycle was observed in children (up to 14 %). Conclusions: Inconsistent timing of CIMT measurement during the cardiac cycle is an avoidable source of imprecision, especially in children, in whom inter-individual differences are smallest. As CIMT is largest at end-diastole, this is the most appropriate time point for consistent and comparable measurements to be made.

Hypertension In Children

Hypertension is a major risk factor for progression of the atherosclerotic process and for developing of degenerative cardiovascular diseases in adulthood. The aim of this study is to evaluate how the measurement of carotid intima - media thickness for prediction of essential hypertension in children can be used.The study group included 81 children and the control group 61 children, all aged between 5 - 17 years and 11 months old, and admitted in Children Hospital Brasov in the period of 2009 � 2014. The study protocol included: BMI, blood pressure and Doppler echography of the common carotid artery for each group. Mean age of the patients from the study group was 13.67 years, 43.20 % girls and 56.80 % boys, while in the control group, the mean age was 14.07 years, 54.10% girls and 45.90 % boys. 70.37% of the children from the study group presented obesity, while in the control group 40.98% were obese. The IMTC study group ranged from 0.52 - 0.69 mm and the limits of the normotensive subjects were 0.32 -0.54 mm. In both groups the obese patients were found to have increased carotid artery intima-media, which means that IMTC was positively correlated with BMI (p=0.000001).It is necessary to identify diagnostic methods easily applicable for children, allowing involvement of the characteristics of the arterial wall in the degenerative pathological processes. Increased intima-media ratio is positively correlated with high values of blood pressure.

Background and Aims: Studies have shown that dipeptidyl peptidase-4 (DDP-4) inhibitors have anti-atherosclerotic effects. However, in the PROLOGUE study, sitagliptin failed to slow the progression of carotid intima-media thickness (CIMT) relative to conventional therapy. We conducted a post hoc analysis of the PROLOGUE study and compared the effects of sitagliptin and conventional therapy on changes in CIMT in subgroups with or without hyperuricemia. Methods: The PROLOGUE study was a randomized controlled trial of 442 patients with type 2 diabetes mellitus (T2DM). Patients were randomized to receive sitagliptin added therapy or conventional therapy. Based on the serum uric acid levels of all study populations in the PROLOGUE study, we divided them into hyperuricemia subgroup ( n = 104) and non-hyperuricemia subgroup ( n = 331). The primary outcome was changed in carotid intima-media thickness (CIMT) parameters compared with baseline during the 24 months treatment period. Results: In the hyperuricemia subgroup, compared with the conventional therapy group, the changes in the mean internal carotid artery (ICA)-IMT and max ICA-IMT at 24 months were significantly lower in the sitagliptin group [−0.233 mm, 95% confidence interval (CI) (−0.419 to 0.046), p = 0.015 and −0.325 mm, 95% CI (−0.583 to −0.068), p = 0.014], although there was no significant difference in the common carotid artery CIMT. Conclusion: The results of our analysis indicated that sitagliptin attenuated the progression of CIMT than conventional therapy in T2DM and hyperuricemia patients.

It has been previously documented that carotid intima-media thickness (cIMT) is a predictor of cardiovascular disease. The aim of this study was to identify clinical parameters associated with an increased cIMT treated hypertensive women. Female patients (n=116) with essential hypertension, aged 40–65 years, were included in this study. Vascular ultrasound was performed and the patients were divided into two groups according to the values of cIMT (< or ≥0.9 mm). Patients with greater cIMT presented significantly higher systolic blood pressure and pulse pressure. Serum HDL-cholesterol was significantly lower and CRP was significantly higher in the same group. There was a significant correlation between cIMT and age (r=0.25,P=0.007), systolic blood pressure (r=0.19,P=0.009), pulse pressure (r=0.30,P=0.001), and LDL-cholesterol (r=0.19,P=0.043). cIMT was correlated to CRP (r=0.31,P=0.007) and negatively correlated to HDL-cholesterol (r=0.33,P=0.001). In logistic regression, only HDL-cholesterol, CRP, and pulse pressure were shown to be independent variables associated to increased cIMT. In conclusion, pulse pressure, HDL-cholesterol, and CRP are variables correlated with cIMT in treated hypertensive women.

Introduction: Atherosclerosis begins in early life. Assessment of comprehensive lipoprotein subclass profiles in adolescents and their relation to atherosclerosis may enhance our understanding of the development of dyslipidemia in early life and inform early vascular prevention Hypothesis: Lipoprotein subclass profiles in adolescents are distinct from those in adults and associate with carotid intima-media thickness (cIMT). Methods: Content of lipids (cholesterol, free cholesterol, triglycerides, phospholipids) and apolipoproteins (apoB-100, apoA1, apoA2) of 17 lipoprotein subclasses (from least dense to densest: VLDL1-6, IDL, LDL1-6, HDL1-4) was measured in plasma of n=1776 14- to 19-year olds (56.6% female) and of n=3217 adults (51.5% female) by nuclear magnetic resonance. cIMT was ascertained by sonography in adolescents. Results: Adolescents compared to adults featured lower triglycerides, total, LDL, and non-HDL cholesterol, and apoB, and higher HDL cholesterol. They showed 27.2 to 60.5% lower triglyceride content of all lipoprotein subclasses and 21.7 to 50.0% lower VLDL lipid content. Concentrations of LDL-4 and LDL-5 were 40.7 to 47.3% lower, with markedly lower levels also of LDL-6 and LDL-3, but 24.3% higher HDL-1 ApoA1. In adolescents, LDL-3, LDL-4, and LDL-5 subclasses were associated with cIMT (difference in cIMT for a 1-SD higher concentration, 4.76 to 5.93μm), whereas no significant association with cIMT was observed for VLDL or HDL. Conclusions: Adolescents showed a markedly different and more favorable lipoprotein profile compared to adults. Dense LDL subclasses were the only subclasses associated with cIMT, implicating them as the potential preferred therapeutic target for primary prevention of cardiovascular disease in adolescents.

OBJECTIVE: To evaluate the effect of a 6-month treatment with slow-release lanreotide (LAN) on cardiovascular risk and atherosclerosis in 24 normotensive patients with active acromegaly (GH=67.4 +/- 12.6 mU/l, IGF--I=866.0 +/- 55.8 microg/l) and 24 healthy subjects sex-, age- and body mass index-matched with the patients (as controls). DESIGN: Open, prospective, multicenter. METHODS: The following were measured before and after 6 months of LAN treatment (dose 60-90 mg/month): fasting GH, IGF-I, LDL, HDL and total cholesterol, triglyceride, glucose, glycosylated hemoglobin, insulin and fibrinogen levels, intima-media thickness (IMT) and blood systolic and diastolic peak velocity (SPV and DPV respectively) in both common carotids. RESULTS: At study entry, insulin, total and LDL cholesterol, triglyceride and fibrinogen levels were higher while HDL cholesterol levels were lower in patients than in controls. At the right (0.88 +/- 0.04 vs 0.77 +/- 0.03 mm, P=0.05) and left (0.93 +/- 0.03 vs 0.78 +/- 0.02 mm, P=0.01) common carotid IMT was significantly higher in patients than in controls; 12 patients and two controls showed an IMT of > or = 1 mm (chi(2)=8.2, P=0.004). After 6 months of LAN treatment, disease control was achieved in 15 patients (62.5%). Insulin, triglyceride and fibrinogen levels were significantly decreased, and a trend toward a decrease of IMT in the right (from 0.90 +/- 0.05 to 0.78 +/- 0.04 mm, P=0.06) and left (from 0.95 +/- 0.04 to 0.84 +/- 0.04 mm, P=0.06) common carotid arteries was observed only in patients with disease control, while SPV and DPV did not change. CONCLUSIONS: LAN treatment for 6 months significantly lowered GH, IGF-I, insulin and fibrinogen levels and reduced IMT of both common carotid arteries in normotensive patients with acromegaly.
