Endothelium-restricted endothelin-1 overexpression in type 1 diabetes worsens atherosclerosis and immune cell infiltration via NOX1.

AIMS: NADPH oxidase (NOX) 1 but not NOX4-dependent oxidative stress plays a role in diabetic vascular disease, including atherosclerosis. Endothelin (ET)-1 has been implicated in diabetes-induced vascular complications. We showed that crossing mice overexpressing human ET-1 selectively in endothelium (eET-1) with apolipoprotein E knockout (Apoe-/-) mice enhanced high-fat diet-induced atherosclerosis in part by increasing oxidative stress. We tested the hypothesis that ET-1 overexpression in the endothelium would worsen atherosclerosis in type 1 diabetes through a mechanism involving NOX1 but not NOX4. METHODS AND RESULTS: Six-week-old male Apoe-/- and eET-1/Apoe-/- mice with or without Nox1 (Nox1-/y) or Nox4 knockout (Nox4-/-) were injected intraperitoneally with either vehicle or streptozotocin (55 mg/kg/day) for 5 days to induce type 1 diabetes and were studied 14 weeks later. ET-1 overexpression increased 2.5-fold and five-fold the atherosclerotic lesion area in the aortic sinus and arch of diabetic Apoe-/- mice, respectively. Deletion of Nox1 reduced aortic arch plaque size by 60%; in contrast, Nox4 knockout increased lesion size by 1.5-fold. ET-1 overexpression decreased aortic sinus and arch plaque alpha smooth muscle cell content by ∼35% and ∼50%, respectively, which was blunted by Nox1 but not Nox4 knockout. Reactive oxygen species production was increased two-fold in aortic arch perivascular fat of diabetic eET-1/Apoe-/- and eET-1/Apoe-/-/Nox4-/- mice but not eET-1/Apoe-/-/Nox1y/- mice. ET-1 overexpression enhanced monocyte/macrophage and CD3+ T-cell infiltration ∼2.7-fold in the aortic arch perivascular fat of diabetic Apoe-/- mice. Both Nox1 and Nox4 knockout blunted CD3+ T-cell infiltration whereas only Nox1 knockout prevented the monocyte/macrophage infiltration in diabetic eET-1/Apoe-/- mice. CONCLUSION: Endothelium ET-1 overexpression enhances the progression of atherosclerosis in type 1 diabetes, perivascular oxidative stress, and inflammation through NOX1.

Potential Role of Endothelin in Early Vascular Aging.

Early vascular aging is a process associated with gradual alterations in the vessels, regarding their structure and function, taking a more rapid course than normal biological aging in the arteries. In the presence of cardiovascular disease, these age-associated alterations are accelerated, contributing in the appearance or the progression of cardiovascular disease, such as high blood pressure, dyslipidemia, smoking and diabetes. Endothelin-1 (ET-1) is the most abundant and important endothelin produced by vascular cells. ET-1 exerts its biological actions through the activation of two receptors: ETA and ETB. Many important functions are mediated by the activation of these receptors, such as cardiovascular remodeling, vasoconstriction, cell proliferation and differentiation, production of extracellular matrix, and water and sodium secretion control. ETA receptor seems to participate in the pathogenesis and development of diseases, such as diabetes, atherosclerosis, systemic and pulmonary hypertension, and cardiac remodeling after myocardial ischemia, whereas ETB receptor seems to prevent the overstimulation of ETA receptor, acting as a clearance receptor. Increased ET-1 system activity may contribute to vascular dysfunction in aging via multiple pathways, such as direct hemodynamic effects, vascular oxidative stress, inflammatory activity, mitogenic stimulation of the vascular smooth muscle cells and fibrotic processes. Endothelin receptor antagonists were considered to be used for the treatment of some diseases like hypertension, diabetes and chronic kidney disease. However, besides pulmonary hypertension, this class is not in clinical use because of the side effects and the availability of safer drugs for the treatment of these diseases.

Vascular smooth muscle cell peroxisome proliferator-activated receptor γ protects against endothelin-1-induced oxidative stress and inflammation.

AIMS: Peroxisome proliferator-activated receptor γ (PPARγ) agonists reduce blood pressure and vascular injury in hypertensive rodents. Pparγ inactivation in vascular smooth muscle cells (VSMC) enhances vascular injury. Transgenic mice overexpressing endothelin (ET)-1 selectively in the endothelium (eET-1) exhibit endothelial dysfunction, increased oxidative stress and inflammation. We hypothesized that inactivation of the Pparγ gene in VSMC (smPparγ-/-) would exaggerate ET-1-induced vascular injury. METHODS AND RESULTS: eET-1, smPparγ-/- and eET-1/smPparγ-/- mice were treated with tamoxifen for 5 days and studied 4 weeks later. SBP was higher in eET-1 and unaffected by smPparγ inactivation. Mesenteric artery vasodilatory responses to acetylcholine were impaired only in smPparγ-/-. N(omega)-Nitro-L-arginine methyl ester abrogated relaxation responses, and the Ednra/Ednrb mRNA ratio was decreased in eET-1/smPparγ-/-, which could indicate that nitric oxide production was enhanced by ET-1 stimulation of endothelin type B receptors. Mesenteric artery media/lumen was greater only in eET-1/smPparγ-/-. Mesenteric artery reactive oxygen species increased in smPparγ and were further enhanced in eET-1/smPparγ-/-. Perivascular fat monocyte/macrophage infiltration was higher in eET-1 and smPparγ and increased further in eET-1/smPparγ-/-. Spleen CD11b+ cells were increased in smPparγ-/- and further enhanced in eET-1/smPparγ-/-, whereas Ly-6C(hi) monocytes increased in eET-1 and smPparγ-/- but not in eET-1/smPparγ-/-. Spleen T regulatory lymphocytes increased in smPparγ and decreased in eET-1, and decreased further in eET-1/smPparγ-/-. CONCLUSION: VSMC Pparγ inactivation exaggerates ET-1-induced vascular injury, supporting a protective role for PPARγ in hypertension through modulation of pro-oxidant and proinflammatory pathways. Paradoxically, ET-1 overexpression preserved endothelial function in smPparγ-/- mice, presumably by enhancing nitric oxide through stimulation of endothelin type B receptors.

Omega-3 fatty acids supplementation improves endothelial function and arterial stiffness in hypertensive patients with hypertriglyceridemia and high cardiovascular risk.

Association between hypertriglyceridemia and cardiovascular (CV) disease is still controversial. The purpose of this study was to compare omega-3 and ciprofibrate effects on the vascular structure and function in low and high CV risk hypertensive patients with hypertriglyceridemia. Twenty-nine adults with triglycerides 150-499 mg/dL were divided into low (<7.5%) and high (≥7.5%) CV risk, randomized to receive omega-3 fatty acids 1800 mg/d or ciprofibrate 100 mg/d for 12 weeks. Treatment was switched after 8-week washout. Clinical evaluation and vascular tests were assessed at baseline and after intervention. Peripheral (131 ± 3 to 125 ± 3 mm Hg, P < .05) and aortic (124 ± 3 to 118 ± 2 mg/dL, P < .05) systolic blood pressure were decreased by ciprofibrate in low-risk patients. In high-risk patients, pulse wave velocity was reduced (10.4 ± 0.4 to 9.4 ± 0.3 m/s, P < .05) and flow-mediated dilation was increased (11.1 ± 1.6 to 13.5 ± 1.2%, P < .05) by omega-3. In conclusion, omega-3 improved arterial stiffness and endothelial function, pointing out the beneficial effect of this therapy on vascular aging, in high-risk patients.

Beneficial Effects of Dietary Nitrate on Endothelial Function and Blood Pressure Levels.

Poor eating habits may represent cardiovascular risk factors since high intake of fat and saturated fatty acids contributes to dyslipidemia, obesity, diabetes mellitus, and hypertension. Thus, nutritional interventions are recognized as important strategies for primary prevention of hypertension and as adjuvants to pharmacological therapies to reduce cardiovascular risk. The DASH (Dietary Approach to Stop Hypertension) plan is one of the most effective strategies for the prevention and nonpharmacological management of hypertension. The beneficial effects of DASH diet on blood pressure might be related to the high inorganic nitrate content of some food products included in this meal plan. The beetroot and other food plants considered as nitrate sources account for approximately 60-80% of the daily nitrate exposure in the western population. The increased levels of nitrite by nitrate intake seem to have beneficial effects in many of the physiological and clinical settings. Several clinical trials are being conducted to determine the broad therapeutic potential of increasing the bioavailability of nitrite in human health and disease, including studies related to vascular aging. In conclusion, the dietary inorganic nitrate seems to represent a promising complementary therapy to support hypertension treatment with benefits for cardiovascular health.

Alterações cardiometabólicas em mulheres hipertensas com obesidade abdominal / Cardiometabolic disorders in Hypertensive women with abdominal obesity

Fundamentos: Estudos mostram o aumento da circunferência abdominal como indicador relevante de riscocardiovascular (RCV) aumentado.Objetivo: Identificar alterações cardíacas estruturais e funcionais em mulheres hipertensas não diabéticas comobesidade abdominal (OA). Métodos: Estudo transversal com 120 mulheres hipertensas, de 40-65 anos, estratificadas em: grupo sem obesidadeabdominal (SOA, n=42) e com obesidade abdominal (COA, n=78), sendo circunferência abdominal < ou ≥88 cm, respectivamente. Realizou-se avaliação clínica, exames bioquímicos, ecoDopplercardiograma e ultrassonografia de carótida.Resultados: A média de idade foi 53±1 anos nos grupos. A pressão arterial (PA) sistólica, embora maior no grupo COA, não atingiu significância estatística (145±2mmHg vs. 140±2mmHg, p=0,098). Grupo COA apresentou maiorPA diastólica (90±1mmHg vs. 85±1mmHg, p <0,05), maior número de critérios (3,1±0,1 vs. 1,4±0,1, p<0,001) e prevalência de síndrome metabólica (62,8% vs. 11,9%, p<0,001). Apesar de glicemias normais, pacientes COA apresentaram índices mais altos de HOMA-IR (2,62±0,22 vs. 1,61±0,17 p<0,01) e HOMA-beta (358±57 vs. 200±22, p<0,05). Na avaliação ecocardiográfica, a função sistólica foi semelhante nos grupos, mas o grupo COA apresentou evidências de disfunção diastólica pelo Doppler tissular e prevalência maior de hipertrofia ventricular esquerda (29,2% vs. 2,4%), sem diferença entre a espessura médio-intimal da carótida.Conclusões: Nesta amostra de hipertensas não diabéticas, a obesidade abdominal foi associada com maiores níveis de pressão arterial diastólica, redução da sensibilidade à insulina e alterações cardíacas, especialmente hipertrofia ventricular esquerda e disfunção diastólica. Contudo, não houve evidência de aterosclerose carotídea subclínica nas hipertensas com e sem obesidade abdominal.

Background: Studies show increased waist circumference as a relevant indicator of increased cardiovascular risk (CVR). Objective: To identify structural and functional cardiac abnormalities in nondiabetic hypertensive women with abdominal obesity (AO). Methods: Cross-sectional study with 120 hypertensive women, aged 40-65, stratified into: group with no abdominal obesity (NAO,n=42) and with abdominal obesity (QAO, n=78), and waist circumference < or ≥88cm, respectively. Clinical evaluation, biochemical tests, Doppler echocardiography and carotid ultrasound were conducted. Results: Average age was 53±1 in the groups. Although the systolic blood pressure (BP) was higher in the WAO group, it did not reach statistical significance (145±2mmHg vs. 140±2mmHg, p=0.098). The WAO group had higher diastolic BP (90±1mmHg vs. 85±1mmHg, p<0.05), greater number of criteria (3.1±0.1 vs. 1.4±0.1, p<0.001) and prevalence of metabolic syndrome (62.8% vs.11.9%; p<0.001). Despite normal blood glucose levels, WAO patients had higher HOMA-IR levels (2.62±0.22 vs. 1.61±0.17 p<0.01) and HOMA-beta levels (358±57 vs. 200±22, p<0.05). In the echocardiographic evaluation, systolic function was similar in bothgroups, but the WAO group presented evidence of diastolic dysfunction by tissue Doppler and higher prevalence of left ventricular hypertrophy (29.2% vs. 2.4%), with no difference between the carotid artery intima-media thickness.Conclusions: In this sample of nondiabetic hypertensive women, abdominal obesity was associated with higher levels of diastolic blood pressure, reduced insulin sensitivity and cardiac issues, especially left ventricular hypertrophy and diastolic dysfunction.However, there was no evidence of subclinical carotid atherosclerosis in hypertensive patients with and without abdominal obesity.

Cost-effectiveness analysis of medical treatment of benign prostatic hyperplasia in the Brazilian public health system.

OBJECTIVE: To perform a cost-effectiveness analysis of medical treatment of benign prostatic hyperplasia (BPH) under Brazilian public health system perspective (Unified Health System--"Sistema Unico de Saude (SUS)"). MATERIAL AND METHODS: A revision of the literature of the medical treatment of BPH using alpha-blockers, 5-alpha-reductase inhibitors and combinations was carried out. A panel of specialists defined the use of public health resources during episodes of acute urinary retention (AUR), the treatment and the evolution of these patients in public hospitals. A model of economic analysis (Markov) predicted the number of episodes of AUR and surgeries (open prostatectomy and transurethral resection of the prostate) related to BPH according to stages of evolution of the disease. Brazilian currency was converted to American dollars according to the theory of Purchasing Power Parity (PPP 2010: US$ 1 = R$ 1.70). RESULTS: The use of finasteride reduced 59.6% of AUR episodes and 57.9% the need of surgery compared to placebo, in a period of six years and taking into account a treatment discontinuity rate of 34%. The mean cost of treatment was R$ 764.11 (US$ 449.78) and R$ 579.57 (US$ 340.92) per patient in the finasteride and placebo groups, respectively. The incremental cost-effectiveness ratio (ICERs) was R$ 4.130 (US$ 2.429) per episode of AUR avoided and R$ 2.735 (US$ 1.609) per episode of surgery avoided. The comparison of finasteride + doxazosine to placebo showed a reduction of 75.7% of AUR episodes and 66.8% of surgeries in a 4 year time horizon, with a ICERs of R$ 21.191 (US$ 12.918) per AUR episodes avoided and R$ 11.980 (US$ 7.047) per surgery avoided. In the sensitivity analysis the adhesion rate to treatment and the cost of finasteride were the main variables that influenced the results. CONCLUSIONS: These findings suggest that the treatment of BPH with finasteride is cost-effective compared to placebo in the Brazilian public health system perspective.

How can diet influence the risk of stroke?

Cerebrovascular diseases are the second cause of mortality in the world, and hypertension is considered a main risk factor for occurrence of stroke. The mechanisms responsible for the increased stroke risk remain unclear. However, dietary interventions have been applied in the management and treatment of their risk factors, which include increased blood pressure levels, obesity, diabetes, and dyslipidemia. Further studies should be conducted to assess the effects of carotenoids, flavonoids, n-3 polyunsaturated fats, and lower salt and high glycemic index intake in risk of stroke.

Evaluation of clinical variables associated with increased carotid intima-media thickness in middle-aged hypertensive women.

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.
