Abstract
Abstract
Several cross-sectional trials have revealed increased arterial stiffness connected with the cardiac autonomic neuropathy in types 2 and 1 diabetic patients. The pathophysiological relationship between arterial stiffness and autonomic dysfunction in diabetes mellitus is still underinvestigated and the question whether the presence of cardiac autonomic neuropathy leads to arterial stiffening or increased arterial stiffness induced autonomic nervous system impairment is still open. Both arterial stiffness and dysfunction of the autonomic nervous system have common pathogenetic pathways, counting state of the chronic hyperinsulinemia and hyperglycemia, increased formation of advanced glycation end products, activation of protein kinase C, development of endothelial dysfunction, and chronic low-grade inflammation. Baroreceptor dysfunction is thought to be one of the possible reasons for the arterial wall stiffening development and progression. On the contrary, violated autonomic nervous system function can affect the vascular tone and by this way alter the large arteries walls elastic properties. Another possible mechanism of attachment and/or development of arterial stiffness is the increased heart rate and autonomic dysfunction corresponding progression. This minireview analyzes the current state of the relationship between the diabetes mellitus and the arterial stiffness. Particular attention is paid to the analysis, interpretation, and application of the results obtained in patients with type 2 diabetes mellitus and diabetic cardiac autonomic neuropathy.

Biochemical and clinical markers of endothelial dysfunction do not outweigh traditional risk factors for the presence of diabetic retinopathy in patients with type 1 diabetes. Diabetol Metab Syndr 2022; 14:141. [PMID: 36167607 PMCID: PMC9516819 DOI: 10.1186/s13098-022-00912-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 09/14/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND This study aimed to evaluate whether soluble vascular cytoadhesive molecule-1 (sVCAM-1), intracellular cytoadhesive molecule-1 (sICAM-1), and endothelial function as assessed by EndoPat outweighed traditional risk factors for the presence of diabetic retinopathy (DR) in patients with type 1 diabetes (T1D). METHODS Patients aged ≥ 12 years completed a clinical-epidemiological questionnaire. Fasting venous blood samples were obtained (lipid profile, glycemic control, and C-reactive protein levels). Vascular reactivity was assessed via peripheral arterial tonometry performed by supplying the reactive hyperemia index (RHI) through the EndoPAT device. sVCAM-1 and sICAM-1 levels were measured using multiplex assays. RESULTS Data were obtained from 187 patients (51.3% female), aged 32 ± 13 years with a disease duration of 14 (6-15) years and mean hemoglobin A1c (HbA1c) of 9.1% ± 2.1%. After adjustments were made, age, HbA1c, arterial blood pressure, and use of drugs that could interfere with endothelial function were found to be associated with DR. No association was noted with sVCAM-1 and sICAM-1 levels and RHI. CONCLUSIONS In our sample, sVCAM-1, sICAM and EndoPAT did not outweigh the traditional DR risk factors, such as age, high HbA1c, arterial blood pressure, and use of drugs that could interfere with endothelial function and are significantly associated with DR. Further prospective studies should evaluate if markers of endothelial dysfunction could predict diabetes-related micro and macrovascular complications in T1D.

Abstract
Windkessel function is governed by conductance artery compliance that is associated with cardiovascular disease in adults independently of other risk factors. Sex-related differences in conductance artery compliance partly explain the sex-related differences in risk of cardiovascular disease. Studies on sex-related differences in conductance artery function in prepubertal children are few and inconclusive. This study determined conductance artery compliance and cardiac function by magnetic resonance imaging in 150 healthy children (75 girls) aged 7-10 years. Any sex-related difference in conductance artery function was determined with correction for other potential predictors in multivariable linear regression models. Our data showed that ascending (crude mean difference 1.11 95% CI (0.22; 2.01)) and descending (crude mean difference 1.10 95% CI (0.09; 1.91)) aortic distensibility were higher in girls, but differences disappeared after adjustment for pubertal status and other identified potential predictors. Systolic and diastolic blood pressure, cardiac output, left ventricle (LV) systolic function, and total peripheral resistance did not differ between the sexes. In girls, heart rate was 7 bpm higher, whereas pulse pressure (by 2 mmHg), and LV end-diastolic volume index (by 7 mL) and stroke volume (by 5 mL) were lower. LV peak filling rate indexed to LV end-diastolic volume was 0.5 s-1 higher in girls. In conclusion, prepubertal girls and boys have equal conductance artery function. Thus, the well-known sex difference in adult conductance artery function seems to develop after the onset of puberty with girls initially increasing aortic distensibility.

Abstract
Severe acute respiratory syndrome coronavirus 2 infection can result in multisystem inflammatory syndrome in children (MIS-C). MIS-C can lead to myocardial dysfunction, heart failure, and multiorgan failure; the primary finding is hyperinflammation. Endothelial dysfunction has not been evaluated in patients with MIS-C. We investigated endothelial dysfunction and arterial stiffness parameters in patients with MIS-C. The study included 38 pediatric patients (20 males and 18 females aged 4-17 years, mean age 8.89 years) with MIS-C. Thirty-eight age- and sex-matched healthy individuals were enrolled as the control group. Systolic and diastolic ventricular measurements and systolic and diastolic measurements of ascending aorta diameter were performed by M-mode echocardiography. Endothelial dysfunction was evaluated using flow-mediated dilation by measuring the brachial artery diameter with a high-resolution probe. The MIS-C group had lower flow-mediated dilation than did the controls. The MIS-C group had decreased aortic strain and aortic distensibility values and correlations between decreased flow-mediated dilation and reduced aortic strain, aortic distensibility, and reduced ejection fraction.Conclusion: The results show that patients with MIS-C had endothelial dysfunction and arterial stiffness. Furthermore, the degree of endothelial dysfunction correlated with reduced ejection fractions.What is Known:•Endothelial dysfunction and arterial stiffness are unknown in patients with MIS-C.•The effect of endothelial dysfunction and arterial stiffness on decreased cardiac function is unknown.What is New:•MIS-C patients have endothelial dysfunction and arterial stiffness.•There is a link between left ventricular dysfunction and reduced endothelial dysfunction in patients with MIS-C.

Abstract
Type 1 diabetes (T1DM) is a strong risk factor for the development of cardiovascular disease. Flow-mediated dilatation (FMD) is an early noninvasive marker of endothelial function and it predicts future cardiovascular disease. However, the changes in FMD among T1DM children are still controversial. The present meta-analysis aimed to investigate whether FMD is impaired in children with T1DM. PubMed, EMBASE, Cochrane library, and Web of Science were searched for studies comparing FMD in children with T1DM and healthy controls. The Newcastle-Ottawa quality assessment scale for case-control studies was used to assess study quality. Data were pooled using a random effects models to obtain the weighted mean differences (WMD) in FMD and 95% CIs. Overall, 19 studies with 1245 patients and 872 healthy controls were included in this meta-analysis. Children with T1DM had significantly lower FMDs compared with healthy controls (WMD: -2.58; 95% CI: -3.36 to -1.81; P < .001). Meta-regression analysis revealed that low-density lipoprotein cholesterol levels impacted the observed difference in FMD between T1DM and healthy children. This meta-analysis showed that T1DM children have impaired endothelial function, which indicates they are at higher risk of developing cardiovascular disease in later life.

Abstract
BACKGROUND Ambient fine particulate matter (PM2.5) is a major threat to cardiovascular health. Endothelial dysfunction is the initiating event associated with the PM2.5-induced cardiovascular disease (CVD). A sensitive marker of endothelial function-circulating von Willebrand factor (vWF), is an independent predictor of adverse clinical outcome in CVD patients. PM2.5 exposure may cause CVD, but the reports of relationship between short-term PM2.5 exposure and circulating vWF are inconsistent. OBJECTIVE To explore the influence of short-term PM2.5 exposure on circulating vWF. METHODS By using a combination of computer and manual retrieval, a systematic literature retrieval was conducted on PubMed, Cochrane Library, Web of Science, Embase and Scopus databases up to October 2019. The heterogeneity among studies was tested by Stata 12.0, and the pooled %-change (percentage change per 10 μg/m3 increase in PM2.5) and its 95% confidence interval (95%CI) were calculated by using random effect model. Sensitivity analysis and publication bias detection were also carried out. RESULTS 12 articles were included in this meta-analysis. Short-term PM2.5 exposure (per 10 μg/m3 increase) was associated with the increased vWF (%-change = 0.41, 95%CI: 0.11-0.71). The pooled effect estimates of subgroup with PM2.5 exposure level < 25 μg/m3 was higher (%-change = 8.26; 95%CI: 1.99-14.53) than that with PM2.5 exposure level ≥ 25 μg/m3 (%-change = 0.36; 95%CI: 0.09-0.63). CONCLUSION Short-term PM2.5 exposure is associated with the increased circulating vWF. It suggests that short-term PM2.5 exposure causes endothelial dysfunction.

Abstract
The prevalence of diabetes mellitus is rising among children and adolescents worldwide. Cardiovascular diseases are the main cause of morbidity and mortality in diabetic patients. We review the impact of diabetes on establishing, during childhood and adolescence, the premises for cardiovascular diseases later in life. Interestingly, it seems that hyperglycemia is not the only factor that establishes an increased cardiovascular risk in adolescence. Other factors have been recognized to play a role in triggering the onset of latent cardiovascular diseases in the pediatric population. Among these cardiovascular risk factors, some are modifiable: glucose variability, hypoglycemia, obesity, insulin resistance, waist circumference, hypertension, dyslipidemia, smoking alcohol, microalbuminuria and smoking. Others are unmodifiable, such as diabetes duration and family history. Among the etiological factors, subclinical endothelial dysfunction represents one of the earliest key players of atherosclerosis and it can be detected during early ages in patients with diabetes. A better assessment of cardiovascular risk in pediatric population still represents a challenge for clinicians, and thus further efforts are required to properly identify and treat pediatric patients who may suffer from cardiovascular disease later in early adulthood.

Abstract
Prevalence of diabetes mellitus has increased drastically over time, especially in more populous countries such as the United States, India, and China. Patients with diabetes have an increased risk of major cardiovascular events such as acute myocardial infarction, cerebrovascular disease, and peripheral vascular disease. Arterial stiffness is a process related to aging and vascular, metabolic, cellular and physiological deterioration. In recent years, it has been described as an independent predictor of cardiovascular mortality and coronary artery disease. Additionally, it plays an important role in the measurement of chronic disease progression. Recent studies have suggested a strong relationship between diabetes mellitus and arterial stiffness since they share a similar pathophysiology involving endothelial dysfunction. The literature has shown that microvascular and macrovascular complications in diabetic patients could be screened and measured with arterial stiffness. Additionally, new evidence proposes that there is a relationship between blood glucose levels, microalbuminuria, and arterial stiffness. Moreover, arterial stiffness predicts cardiovascular risk and is independently associated with mortality in diabetic patients. Abnormal arterial stiffness values in diabetic patients should alert the clinician to the presence of vascular disease, which merits early study and treatment. We await more studies to determine if arterial stiffness could be considered a routine useful non-invasive tool in the evaluation of diabetic patients. There is enough evidence to conclude that arterial stiffness is related to the progression of diabetes mellitus.

Abstract
Chronic vascular complications are the major causes of death and disability of type 2 diabetes mellitus (T2DM) patients. von Willebrand factor (vWF) is involved in pathogenesis of cardiovascular diseases (CVD). Previous studies showed elevated plasma levels of vWF in T2DM patients with CVD, but the association has not been validated. The aim of this meta-analysis was to compare plasma levels of vWF in T2DM patients with and without CVD. We performed a meta-analysis based on published case-control studies of vWF in T2DM patients with and without CVD indexed in PubMed and other databases updated to April 2018. After independently assessing methodological quality and extracting data, 9 eligible studies were obtained including 576 cases and 632 controls. The standard mean difference (SMD) and 95% confidence intervals (95% CI) were calculated using random-effects model. Meta-analysis showed that plasma level of vWF was significantly higher in T2DM patients with CVD than T2DM patients without CVD (SMD = 0.61; 95% CI, 0.32-0.90; P < .00001). Subgroup and sensitivity analyses confirmed the robustness of the results. Plasma levels of vWF are significantly elevated in patients with T2DM complicated by CVD. This study helps further characterize the prognostic value of vWF for cardiovascular complications in T2DM patients.

Abstract
BACKGROUND Endothelial dysfunction (ED) is a marker of vascular damage. Glycated hemoglobin (A1C) predicts vascular complications. The EndoPAT (peripheral arterial tonometry) device calculates the reactive hyperemic index (RHI), a measure of endothelial function. The greater the vasodilation, the higher the RHI. We hypothesized that children with poorly-controlled diabetes mellitus (DM) and non-diabetes mellitus (NDM) obese children have ED. METHODS A cross-sectional study using the EndoPAT device was performed on children with poorly-controlled DM and NDM children. ANOVA, t-test, Mann-Whitney U test, multiple linear regression and Spearman correlation were used. RESULTS Of 58 children that completed the study (aged 13.1 ± 3.42 years), 33 with type 1 diabetes (T1DM), 8 with type 2 diabetes (T2DM) and 17 were NDM obese children. Eighty-five percent were African-American, 60% were female and 79% entered puberty. The RHI of children with DM (1.42 ± 0.48) versus NDM obese group (1.40 ± 0.34) was not different (P = 0.86) regardless of the type of DM or body mass index. In the DM group, for every 1% increase in latest A1C, the RHI decreased by 0.097 (P = 0.01) after adjusting for age, gender, and type of DM. The RHI of DM patients with latest A1C of < 10% (1.70 ± 0.58) versus those with A1C ≥10% (1.21 ± 0.19) was statistically different (P = 0.02). In the total study population, males had significantly lower RHI (1.28 ± 0.36) when compared to females (1.51 ± 0.46), P = 0.04 but this difference disappeared when considering pubertal status and type of diabetes. CONCLUSIONS Our data showed that patients with poorly-controlled DM as reflected by latest A1C of ≥ 10% had worse endothelial function as reflected by lower RHI score.

Early Endothelial Dysfunction in Type 1 Diabetes Is Accompanied by an Impairment of Vascular Smooth Muscle Function: A Meta-Analysis. Front Endocrinol (Lausanne) 2020; 11:203. [PMID: 32362871 PMCID: PMC7180178 DOI: 10.3389/fendo.2020.00203] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Accepted: 03/23/2020] [Indexed: 12/15/2022] Open
Abstract
Background: A large yet heterogeneous body of literature exists suggesting that endothelial dysfunction appears early in type 1 diabetes, due to hyperglycemia-induced oxidative stress. The latter may also affect vascular smooth muscles (VSM) function, a layer albeit less frequently considered in that pathology. This meta-analysis aims at evaluating the extent, and the contributing risk factors, of early endothelial dysfunction, and of the possible concomitant VSM dysfunction, in type 1 diabetes. Methods: PubMed, Web of Sciences, Cochrane Library databases were screened from their respective inceptions until October 2019. We included studies comparing vasodilatory capacity depending or not on endothelium (i.e., endothelial function or VSM function, respectively) in patients with uncomplicated type 1 diabetes and healthy controls. Results: Fifty-eight articles studying endothelium-dependent function, among which 21 studies also assessed VSM, were included. Global analyses revealed an impairment of standardized mean difference (SMD) (Cohen's d) of endothelial function: -0.61 (95% CI: -0.79, -0.44) but also of VSM SMD: -0.32 (95% CI: -0.57, -0.07). The type of stimuli used (i.e., exercise, occlusion-reperfusion, pharmacological substances, heat) did not influence the impairment of the vasodilatory capacity. Endothelial dysfunction appeared more pronounced within macrovascular than microvascular beds. The latter was particularly altered in cases of poor glycemic control [HbA1c > 67 mmol/mol (8.3%)]. Conclusions: This meta-analysis not only corroborates the presence of an early impairment of endothelial function, even in response to physiological stimuli like exercise, but also highlights a VSM dysfunction in children and adults with type 1 diabetes. Endothelial dysfunction seems to be more pronounced in large than small vessels, fostering the debate on their relative temporal appearance.

Abstract
Patients with diabetes experience increased cardiovascular risk that is not fully explained by deficient glycemic control or traditional cardiovascular risk factors such as smoking and hypercholesterolemia. Asymptomatic patients with diabetes show structural and functional vascular damage that includes impaired vasodilation, arterial stiffness, increased intima-media thickness and calcification of the arterial wall. Subclinical vascular injury associated with diabetes predicts subsequent manifestations of cardiovascular disease, such as ischemic heart disease, peripheral artery disease and stroke. Noninvasive detection of subclinical vascular disease is commonly used to estimate cardiovascular risk associated to diabetes. Longitudinal studies in normotensive subjects show that arterial stiffness at baseline is associated with a greater risk for future hypertension independently of established risk factors. In patients with type 2 diabetes, vascular disease begins to develop during the latent phase of insulin resistance, long before the clinical diagnosis of diabetes. In contrast, patients with type 1 diabetes do not manifest vascular injury when they are first diagnosed due to insulin deficiency, as they lack the preceding period of insulin resistance. These findings suggest that insulin resistance plays an important role in the development of early vascular disease associated with diabetes. Cross-sectional and prospective studies confirm that insulin resistance is associated with subclinical vascular injury in patients with diabetes, independently of standard cardiovascular risk factors. Asymptomatic vascular disease associated with diabetes begins to occur early in life having been documented in children and adolescents. Insulin resistance should be considered a therapeutic target in order to prevent the vascular complications associated with diabetes.

Abstract
Background Cardiovascular disease (CVD) is the end result of vascular aging and atherosclerosis, having its origins in childhood. The aim of our study was to compare arterial stiffness (AS) and intima-media thickness (IMT) as markers of an early vascular damage between obese adolescents, adolescents with diabetes type 1 (T1D) and lean control subjects. Methods We analyzed AS and IMT in 68 obese adolescents (13.27±2.31 years), 42 adolescents with T1D (14.95±2.35 years) lasting over 5 years and 38 controls (15.02±1.94 years). AS (measured by pulse wave velocity [PWV], arterial compliance [AC] and β-stiffness) and IMT were assessed using an e-tracking ultrasound method. Results A significant difference between the groups was found for AC (p=0.022) and PWV (p=0.010), with the lowest compliance and higher velocities in T1D patients. When corrected for age, the difference in AC among the groups did not reach a statistical difference (p=0.059). Correlation analysis in the obese adolescents showed lower AC in females (p=0.041), with higher systolic blood pressure (SBP) (p=0.032). In T1D adolescents, disease duration was the strongest determinant of AS (AC p=0.028, β p=0.029 and PWV p=0.003), followed by body mass index (BMI; PWV p=0.008; β p=0.033), SBP (AC p<0.001; PWV p=0.023), diastolic BP (AC p=0.049; PWV p=0.048) and HbA1c (PWV p=0.048). No significant correlations were found for AS measures or IMT with sex, age, BMI, Tanner stage or BP levels in controls. Conclusions Early vascular damage is more pronounced in T1D adolescents than in obese or lean adolescents, which may emphasize the impact of hyperglycemia as a major threat for cardiovascular health.

Abstract
Aims Arterial stiffness is a strong predictor of cardiovascular events. We aimed to assess the impact of type 1 diabetes (T1D) on arterial stiffness and cardiac function in young adults. Methods and results Aortic pulse wave velocity (PWV), distensibility, left ventricular (LV) function and LV mass were measured by cardiovascular magnetic resonance imaging (CMR) in 47 T1D patients and 33 healthy controls. All were participants in the Atherosclerosis and Childhood Diabetes study, with baseline values registered 5 years previously. The patients had a mean age of 20.8 years and a median duration of diabetes of 10.0 years. PWV was significantly higher in the diabetes group compared with controls, mean 4.10 (SD = 4.58) vs. 3.90 (SD = 4.04) m/s, P = 0.045. In the diabetes group, insulin pump users at baseline had lower PWV than multiple injection users, mean 3.94 (SD = 0.38) vs. 4.23 (SD = 0.48) m/s, P = 0.028. Also in the diabetes group, multiple regression analysis identified C-reactive protein (CRP), female gender and insulin pump use as independent baseline risk factors for PWV 5 years later. There was no difference in cardiac function or LV mass between the diabetes and control groups. Conclusion In this prospective study, we found increased PWV assessed by CMR in young adults with T1D compared with controls. Also, CRP, female gender and insulin pump use emerged as independent baseline risk factors for PWV 5 years later.

Abstract
BACKGROUND Hypertension is strongly related to arterial stiffness in a cause-effect fashion. Diabetes mellitus is also thought to determine vascular damage, mostly by means of advanced glycosylation end-products (AGEs). Aim of our study was to study the role of type 2 diabetes mellitus (T2DM) as regard ascending aortic elastic properties in hypertensive patients. METHODS We prospectively enrolled outpatients with hypertension (n = 99) and type 2 diabetes mellitus plus hypertension (n = 42) without cardiovascular events. They underwent a transthoracic echocardiography to measure aortic diameters, aortic elastic properties (ie, compliance, distensibility, stiffness index, Peterson's elastic modulus, pulse wave velocity, M-mode strain), tissue Doppler imaging (TDI) to calculate diastolic (E' and A') and systolic (S') velocities, and tissue strain. Multivariable analysis was run to assess the association between T2DM and these variables after correcting for possible confounders (age, sex, body mass index [BMI], dyslipidemia). RESULTS The two groups did not differ as regards age, sex, BMI, and blood pressure. However, T2DM patients were more likely to be dyslipidemic (43% vs 71%, P = .003). Aortic diameters were similar in the two groups, but the aortic elastic properties significantly more impaired in T2DM group. At multivariable analysis, stiffness index, Peterson's elastic modulus, the TDI waves, and the tissue strain remained associated with the co-presence of T2DM and hypertension. CONCLUSION Our data suggest that people suffering from both T2DM and hypertension have more impaired aortic elastic properties than those hypertensive alone. Considering the prognostic role of aortic stiffness, these patients may benefit from a closer follow-up.

Abstract
OBJECTIVE This study aimed at assessing the endothelial function in patients with Type 1 diabetes (T1DM) using flow-mediated dilation (FMD) response and carotid artery intima-media thickness (CIMT). MATERIALS AND METHODS This study enrolled 32 T1DM patients (mean disease duration 4.1 years) and 28 age-matched controls (CTL Group). Endothelial function and CIMT were assessed with high-resolution ultrasound using standardized offline measurements. RESULTS FMD was significantly lower in patients in the T1DM Group (8.9 ± 3.2%) compared with those in the CTL Group (13.3 ± 4.3%; P-value < 0.0001). Similarly, CIMT differed significantly between T1DM patients (0.525 ± 0.03 mm) and controls (0.508 ± 0.03 mm; P-value = 0.041). Even though, the values are within the normal range for age. CONCLUSIONS Patients with T1DM have impaired endothelial function characterized by reduced FMD when compared to controls. However, vascular remodeling as seen by increases in CIMT was not found in this study.

Abstract
OBJECTIVE Metabolic impairment in type 1 diabetes mellitus (T1DM) with poor glycemic control causes insulin resistance, non-alcoholic fatty liver disease (NAFLD), atherosclerosis, and increased carotid intima-media thickness (CIMT). Fetuin-A has a protective effect in cardiovascular disorders and is increased in hepatosteatosis. We aimed to investigate the reliability of fetuin-A levels in early detection of diabetic complications in children with T1DM and to identify a cut-off value that may show poor metabolic control. METHODS The study included 80 patients who had T1DM for at least 5 years and who had no chronic complications or an auto-immune disorder. Blood samples were drawn to measure hemoglobin A1c (HbA1c), biochemical parameters, and fetuin-A levels. Anthropometric parameters were also measured. Percent body fat was calculated. Hepatosteatosis and CIMT were assessed by sonography. RESULTS Mean age of the patients was 13.5 years. Grade 1 hepatosteatosis was detected in 10%. Patients were stratified into 2 groups based on presence of NAFLD. Fetuin-A level was increased in patients with NAFLD. We identified a fetuin-A cut-off value (514.28 ng/mL; sensitivity: 47.34; specificity: 96.72) that may predict NAFLD. HbA1c and total cholesterol levels were found to be higher in patients with fetuin-A levels above higher the cut-off value. CONCLUSION Fetuin-A is a reliable parameter in the prediction of complications and poor glycemic control in patients with T1DM.

Abstract
PURPOSE OF REVIEW Patients with type 1 diabetes have increased risk for cardiovascular disease. The purpose of this review is to examine the following: i) current evidence for subclinical cardiovascular disease (CVD) in children with type 1 diabetes (T1DM) ii) known modifiable risk factors for CVD and their relationship to subclinical CVD in this population iii) studies that have addressed these risk factors in order to improve CVD outcomes in children with T1DM RECENT FINDINGS: Subclinical CVD presents in children as increased carotid intima-media thickness, increased arterial stiffness, and endothelial and myocardial dysfunction. Modifiable risk factors for CVD include hyperglycemia, hyperlipidemia, obesity, hypertension, depression, and autonomic dysfunction. Very few randomized controlled studies have been done in children with T1DM to examine how modification of these risk factors can affect their CVD. Children with T1DM have subclinical CVD and multiple modifiable risk factors for CVD. More research is needed to define how modification of these factors affects the progression of CVD.

ARCHIVES OF ENDOCRINOLOGY AND METABOLISM 2017; 61:476-483. [PMID: 28658349 PMCID: PMC10522258 DOI: 10.1590/2359-3997000000271] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2015] [Accepted: 02/01/2017] [Indexed: 11/22/2022]
Abstract
OBJECTIVE The purpose of this study was to verify the presence of endothelial dysfunction and initial structural atherosclerotic changes in children with Type 1 diabetes mellitus (T1DM). SUBJECTS AND METHODS The study population comprised 31 diabetic children aged 6 to 12 years, divided into two subgroups according to the duration of the T1DM diagnosis: subgroup 1, with less than 5 years elapsed since diagnosis, and subgroup 2, with more than 5 years elapsed since diagnosis. The control group comprised 58 age-matched healthy children. Ultrasonographic techniques were used to measure the flow-mediated dilatation (FMD) of the brachial artery and the intima-media thickness (IMT) of the carotid arteries. RESULTS Children with T1DM with longer disease duration showed significantly decreased mean values of FMD compared with those in the control group. No significant differences between the groups were found in relation to IMT. The FMD percentage presented a moderate negative correlation with glycated hemoglobin (HbA1c) and fasting glucose levels. CONCLUSION Our findings suggest that endothelial dysfunction may be already present in children with 5 years or more elapsed since diagnosis, even in the absence of atherosclerotic structural changes. The decreased vasodilation response correlated with hyperglycemia.

Abstract
OBJECTIVE To determine the effects of omitting meal time insulin on arterial stiffness in children with type 1 diabetes. RESEARCH DESIGN AND METHODS In this prospective, randomized, crossover study, radial artery tonometry and augmentation index adjusted to heart rate 75 (AI75 ) were used to measure arterial stiffness. Children were randomized to receive or omit premeal insulin and completed the crossover portion of the study on a subsequent day. AI75 was determined when fasting, 1, and 2 h postmeal. RESULTS When comparing change in AI75 from baseline to 1 h and baseline to 2 h, when subjects received premeal insulin vs. no insulin, AI75 was 4.5 units lower at 1 h (p = 0.011, 95% CI:1.1 lower to 8 lower) and 4.3 units lower at 2 h (p = 0.062, 95% CI: 0.2 higher to 8.9 lower) (n = 40). CONCLUSIONS Arterial stiffness is decreased by premeal insulin in children with type 1 diabetes.

Abstract
BACKGROUND Reduced diastolic function is an early sign of diabetes cardiomyopathy in adults and is associated with elevated levels of HbA1c and advanced glycation end products (AGEs). OBJECTIVE To assess the associations between early reduced diastolic function and elevated levels of HbA1c and AGEs in children and adolescents with type 1 diabetes (T1D). METHODS One hundred fourty six T1D patients (age 8-18 years) without known diabetic complications were examined with tissue Doppler imaging and stratified into two groups according to diastolic function. A clinical examination and ultrasound of the common carotid arteries were performed. Methylglyoxal-derived hydroimidazolone-1 (MG-H1) was measured by immunoassay. RESULTS At inclusion, 36 (25%) participants were stratified into a low diastolic function group (E'/A'-ratio < 2.0). Compared to the rest of the T1D children, these participants had higher body mass index (BMI), 22.8 (SD = 4.0) vs. 20.1 (SD = 3.4) kg/m2, p < 0.001, higher systolic blood pressure 104.2 (SD = 8.7) vs. 99.7 (SD = 9.3) mmHg, p = 0.010, and higher diastolic blood pressure, 63.6 (SD = 8.3) vs. 59.9 (SD = 7.9) mmHg, p = 0.016. The distensibility coefficient was lower, 0.035 (SD = 0.010) vs. 0.042 (SD = 0.02) kPa-1, p = 0.013, Young's modulus higher, 429 (SD = 106) vs. 365 (SD = 143), p = 0.009, and MG-H1 higher, 163.9 (SD = 39.2) vs. 150.3 (SD = 33.4) U/ml, p = 0.046. There was no difference in carotid intima-media thickness between the groups. There were no associations between reduced diastolic function and years from diagnosis, HBA1c, mean HBA1c, CRP or calculated glycemic burden. Logistic regression analysis showed that BMI was an independent risk factor for E'/A'-ratio as well as a non-significant, but relatively large effect size for MG-H1, indicating a possible role for AGEs. CONCLUSIONS Early signs of reduced diastolic function in children and adolescents with T1D had higher BMI, but not higher HbA1c. They also had elevated serum levels of the advanced glycation end product MG-H1, higher blood pressure and increased stiffness of the common carotid artery, but these associations did not reach statistical significance when tested in a logistic regression model.

Abstract
Background Cardiac dysfunction in patients with type 1 diabetes (T1D) represents one of the serious complications. To evaluate the cardiac function in children with T1D by conventional echocardiography and tissue Doppler imaging (TDI). Methods The study included 40 T1D patients (age between 6 and 16 years) with > 5 years duration of diabetes and 42 healthy control children. The patients were subjected to clinical evaluation and laboratory investigations [glycosylated hemoglobin A1c (HbA1c), serum lipids and lipoproteins]. Conventional echocardiography and TDI were performed to patients and controls. Results The patients had lower early diastolic filling velocity (E wave) of the tricuspid valve and mitral valves with a p value of (0.000 and 0.006, respectively). TDI revealed that patients had lower S′velocity of the T1D, shorter isovolumic contraction time, longer isovolumic relaxation time and lower E/E′ of the right ventricle than controls (p value 0.002, 0.001, 0.004, 0.003, and 0.016, respectively). The left ventricle (LV)-T1D of the patients was significantly higher (p value 0.02). Twenty eight patients had poor glycemic control without significant differences between them and those with good glycemic control regarding echocardiographic data. Patients with dyslipidemia (13 patients) had higher late diastolic filling velocity of the mitral valve (A) and the lower LV late tissue velocity (A′) (p wave 0.047 and 0.015). No correlation existed between the duration of illness or the level of HbA1c and the echocardiographic parameters. Conclusion Diabetic children have evidence of echocardiographic diastolic dysfunctions. Periodic cardiac evaluation with both conventional and tissue Doppler echocardiography is recommended for early detection of this dysfunction.

Abstract
BACKGROUND Endothelial dysfunction may be involved in the pathophysiology of cardiac abnormalities in patients with diabetes mellitus (DM). A correlation between endothelial dysfunction and diastolic dysfunction in patients with type 1 DM has been demonstrated, but this relationship has not been well investigated in type 2 DM. OBJECTIVE Compare groups of patients with type 2 DM and hypertension with and without diastolic dysfunction using endothelial function indexes, and to assess whether correlations exist between the diastolic function and the endothelial function indexes. METHOD This was a cross-sectional study of 34 men and women with type 2 DM and hypertension who were aged between 40 and 70 years and were categorized based on assessments of their Doppler echocardiographic parameters as having normal (14 patients) and abnormal (20 patients) diastolic function. Flow-mediated dilatation (FMD) assessments of the brachial artery evaluated the patients' endothelial function. RESULTS The mean maximum FMD was 7.15 ± 2.80% for the patients with diastolic dysfunction and it was 11.85 ± 4.77% for the patients with normal diastolic function (p = 0.004). Correlations existed between the maximum FMD and the E/e' ratio (p = 0.040, r = -0.354) and the early wave velocity (e') at the lateral mitral annulus (p = 0.002, r = 0.509). CONCLUSION The endothelial function assessed by FMD was worse in hypertensive diabetic patients with diastolic dysfunction. There were correlations between the diastolic function indexes and the endothelial function indexes in our sample.

Abstract
OBJECTIVE To examine the associations between inflammatory markers, coagulation and fibrinolysis parameters, and microvascular complications in 182 Chinese patients with type 2 diabetes mellitus (T2DM) who sought treatment at a large hospital in Zhejiang province, China. METHODS We investigated the relationships of blood inflammatory markers with hemostatic markers in 87 patients with T2DM who did not have complications and 95 patients with T2DM who had microvascular complications. RESULTS C-reactive protein (CRP) and interleukin-6 (IL-6) were significantly correlated with fibrinogen, thrombin-antithrombin III complex (TAT III), plasminogen activator inhibitor-1 (PAI-1), von Willebrand factor (vWF), and coagulation factors (F) VII in patients with T2DM who had microvascular complications (P <.05). Based on logistic regression analysis, the highest-tertile groups of fibrinogen, FVII, and FVIII, corresponded to a greater risk of high CRP, whereas risk of high IL-6 was significantly greater in the groups with highest-tertile values for fibrinogen, FVII, TAT III, PAI-1, and activated protein C (APC). CONCLUSIONS Elevated levels of CRP and IL-6 might be associated with increased coagulability and a tendency towards thrombus formation in patients with T2DM who have microvascular complications.

Abstract
We have previously reported that advanced glycation end products activated Rho-associated protein kinase and p38 mitogen-activated protein kinase, causing endothelial hyperpermeability. However, the mechanisms involved were not fully clarified. Here, we explored the role of myosin light chain kinase in advanced glycation end product-induced endothelial hyperpermeability. Myosin light chain phosphorylation significantly increased by advanced glycation end products in endothelial cells in a time- and dose-dependent manner, indicating that myosin light chain phosphorylation is involved in the advanced glycation end product pathway. Advanced glycation end products also induced myosin phosphatase-targeting subunit 1 phosphorylation, and small interfering RNA knockdown of the receptor for advanced glycation end products, or blocking myosin light chain kinase with its inhibitor, ML-7, or small interfering RNA abated advanced glycation end product-induced myosin light chain phosphorylation. Advanced glycation end product-induced F-actin rearrangement and endothelial hyperpermeability were also diminished by inhibition of receptor for advanced glycation end product or myosin light chain kinase signalling. Moreover, inhibiting myosin light chain kinase with ML-7 or blocking receptor for advanced glycation end product with its neutralizing antibody attenuated advanced glycation end product-induced microvascular hyperpermeability. Our findings suggest a novel role for myosin light chain and myosin light chain kinase in advanced glycation end product-induced endothelial hyperpermeability.

Abstract
BACKGROUND Adenotonsillar hypertrophy can produce cardiopulmonary disease in children. However, it is unclear whether adenotonsillar hypertrophy causes atherosclerosis. This study evaluated carotid intimamedia thickness and carotid arterial stiffness in children with adenotonsillar hypertrophy. METHODS The study included 40 children with adenotonsillar hypertrophy (age: 5-10 years) and 36 healthy children with similar age and body mass index. Systolic blood pressure, diastolic blood pressure, and pulse pressure were measured in all subjects. Carotid intima-media thickness, carotid arterial systolic diameter, and carotid arterial diastolic diameter were measured using a high-resolution ultrasound device. Based on these measurements, carotid arterial strain, carotid artery distensibility, beta stiffness index, and elasticity modulus were calculated. RESULTS Carotid intima-media thickness was greater in children with adenotonsillar hypertrophy (0.36±0.05 mm vs. 0.34±0.04 mm, P=0.02) compared to healthy controls. Beta stiffness index (3.01±1.22 vs. 2.98±0.98, P=0.85), elasticity modulus (231.39±99.23 vs. 226.46±83.20, P=0.88), carotid arterial strain (0.17±0.06 vs. 0.17±0.04, P=0.95), and carotid artery distensibility (13.14±3.88 vs. 12.92±3.84, P=0.75) were similar between children with adenotonsillar hypertrophy and the healthy controls. CONCLUSIONS The present study revealed increased carotid intima-media thickness in children with adenotonsillar hypertrophy. The risk of subclinical atherosclerosis may be higher in children with adenotonsillar hypertrophy.

Abstract
OBJECTIVE To investigate the effect of low-intensity pulsed ultrasound (LIPUS) as a treatment for erectile dysfunction (ED) in a rat model of type I diabetes mellitus (DM) induced by streptozotocin (STZ). MATERIALS AND METHODS Seventy male Sprague-Dawley rats were randomly assigned to 2 cohorts: a normal control (NC) group and an STZ-induced DM group, which was further subdivided into DM, DM+LIPUS 100, DM+LIPUS 200, and DM+LIPUS 300 groups and a DM+LESWT (low-energy shock wave therapy) 300 positive control group. Animals in the LIPUS subgroups were treated at different energy levels (100, 200, and 300 mW/cm(2)) for 3 minutes, and animals in the LESWT group received 300 shocks at 0.09 mJ/mm(2). All procedures were repeated 3 times per week for 2 weeks. After a 2-week wash-out period, intracavernous pressure (ICP) was measured; the midpenile region was examined histologically; and VEGF, αSMA, eNOS, and nNOS expression, and activity of the TGF-β1/Smad/CTGF signaling pathway were examined in penile tissue by Western blot analysis. RESULTS LIPUS therapy significantly improved erectile function in diabetic rats, as evidenced by enhanced ICP levels, increased endothelial and smooth muscle content, a higher collagen I/collagen III ratio, increased quantity of elastic fibers, and elevated eNOS and nNOS expression. Interestingly, LIPUS was also associated with downregulation of the TGF-β1/Smad/CTGF signaling pathway in penile tissue, whose activation is correlated with ED pathology. CONCLUSION LIPUS therapy improved erectile function and reversed pathologic changes in penile tissue of STZ-induced diabetic rats. LIPUS therapy has potential as a noninvasive therapy for diabetic ED in the clinic.

Abstract
AIM To derive a more precise estimation of carotid intima-media thickness (CIMT) levels in patients with type 1 diabetes mellitus (T1DM) by meta-analysis. METHODS PubMed and Embase databases were searched to identify all available studies comparing CIMT levels between T1DM group and control group. Meta-analysis was performed to compare the difference of overall mean CIMT levels between the two groups. Publication bias was evaluated by funnel plot, Begg' test and Egger' test. Meta-regression analysis was conducted to investigate the influential factors on CIMT difference. The meta-analysis was conducted by STATA 12.0 software. RESULTS A total of 1840 articles were obtained after searching databases; 47 studies were finally included in the meta-analysis. Significant heterogeneity was observed among these studies (Q = 768.75, P < 0.001, I(2) = 94.0%). Compared with the control group, the T1DM group had significantly higher CIMT levels (standardized mean difference: 1.01, 95% CI: 0.75-1.28; P < 0.001). A likely source of heterogeneity was Newcastle-Ottawa Scale (NOS) scores and sample size ratio of patents and controls. The funnel plot did not show a skewed or asymmetrical shape, and the result of Begg' test and Egger' test was P = 0.178 and P = 0.145 respectively. Accordingly, it could be assumed that publication bias was not present. CONCLUSION T1DM patients have significantly increased CIMT levels compared to control subjects.

The wall of blood vessels including those in choroids may be harmed by several repeated and/or prolonged mechanical, physical, chemical, microbiological, immunologic, and genetic impacts (risk factors), which may trigger a protracted response, the so-called host defense response. As a consequence, pathological changes resulting in vascular injury (e. g. atherosclerosis, age-related macular degeneration) may be evolved. Risk factors can also act directly on the endothelium through an increased production of reactive oxygen species promoting an endothelial activation, which leads to endothelial dysfunction, the onset of vascular disease. Thus, endothelial dysfunction is a link between the harmful stimulus and vascular injury; any kind of harmful stimuli may trigger the defensive chain that results in inflammation that may lead to vascular injury. It has been shown that even early age-related macular degeneration is associated with the presence of diffuse arterial disease and patients with early age-related macular degeneration demonstrate signs of systemic and retinal vascular alterations. Chronic inflammation, a feature of AMD, is tightly linked to diseases associated with ED: AMD is accompanied by a general inflammatory response, in the form of complement system activation, similar to that observed in degenerative vascular diseases such as atherosclerosis. All these facts indicate that age-related macular degeneration may be a vascular disease (or part of a systemic vasculopathy). This recognition could have therapeutic implications because restoration of endothelial dysfunction may prevent the development or improve vascular disease resulting in prevention or improvement of age-related macular degeneration as well.

Abstract
Background Previous studies suggested an impaired endothelial function in patients with diabetes. However, the validity of this finding may be limited by the lack of adequate adjustment for further cardiovascular confounders. We assessed endothelial function as measured by flow-mediated dilation (FMD) of the brachial artery in patients with either type 1 or type 2 diabetes in comparison with non-diabetic controls. Methods The study population comprised 1487 subjects including 122 subjects with type 2 diabetes, aged 25 to 85, from the population-based Study of Health in Pomerania, and 65 outpatients, aged 23 to 75, with type 1 diabetes. FMD measurements were performed using standardized ultrasound techniques. Subjects with type 1 and type 2 diabetes were matched 1:4 to healthy controls using propensity score matching. Results Neither type 1 diabetes (β = 0.142; SE = 0.568, p = 0.803) nor type 2 diabetes (β = 0.107; SE = 0.340, p = 0.752) were significantly associated with FMD in comparison with their non-diabetic controls after adjustment for major cardiovascular confounders like age, gender, body mass index, smoking status, hypertension, antihypertensive medication, LDL and HDL cholesterol levels. Conclusions In this population-based study comparing adjusted FMD values of diabetic individuals with adequately matched controls, propensity score analyses revealed no association between diabetes and endothelial function. Since these findings are in discordance with the majority of previous reports, we suggest performing similar analyses using data from other population-based studies.
