Ekholm M, Kahan T. The Impact of the Renin-Angiotensin-Aldosterone System on Inflammation, Coagulation, and Atherothrombotic Complications, and to Aggravated COVID-19. Front Pharmacol 2021; 12:640185. [PMID: 34220496 PMCID: PMC8245685 DOI: 10.3389/fphar.2021.640185] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Accepted: 06/07/2021] [Indexed: 12/20/2022] Open
Abstract
Atherosclerosis is considered a disease caused by a chronic inflammation, associated with endothelial dysfunction, and several mediators of inflammation are up-regulated in subjects with atherosclerotic disease. Healthy, intact endothelium exhibits an antithrombotic, protective surface between the vascular lumen and vascular smooth muscle cells in the vessel wall. Oxidative stress is an imbalance between anti- and prooxidants, with a subsequent increase of reactive oxygen species, leading to tissue damage. The renin-angiotensin-aldosterone system is of vital importance in the pathobiology of vascular disease. Convincing data indicate that angiotensin II accelerates hypertension and augments the production of reactive oxygen species. This leads to the generation of a proinflammatory phenotype in human endothelial and vascular smooth muscle cells by the up-regulation of adhesion molecules, chemokines and cytokines. In addition, angiotensin II also seems to increase thrombin generation, possibly via a direct impact on tissue factor. However, the mechanism of cross-talk between inflammation and haemostasis can also contribute to prothrombotic states in inflammatory environments. Thus, blocking of the renin-angiotensin-aldosterone system might be an approach to reduce both inflammatory and thrombotic complications in high-risk patients. During COVID-19, the renin-angiotensin-aldosterone system may be activated. The levels of angiotensin II could contribute to the ongoing inflammation, which might result in a cytokine storm, a complication that significantly impairs prognosis. At the outbreak of COVID-19 concerns were raised about the use of angiotensin converting enzyme inhibitors and angiotensin receptor blocker drugs in patients with COVID-19 and hypertension or other cardiovascular comorbidities. However, the present evidence is in favor of continuing to use of these drugs. Based on experimental evidence, blocking the renin-angiotensin-aldosterone system might even exert a potentially protective influence in the setting of COVID-19.

Effects of Angiotensin-Converting Enzyme Inhibitors on Arterial Stiffness: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Cardiovasc Ther 2020; 2020:7056184. [PMID: 32190121 PMCID: PMC7068147 DOI: 10.1155/2020/7056184] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Revised: 12/31/2019] [Accepted: 01/08/2020] [Indexed: 12/11/2022] Open
Abstract
To determine the effects of ACEIs on arterial stiffness, a meta-analysis of randomized controlled trials was conducted. Relevant articles that investigated the effects of ACEIs on arterial stiffness from PubMed, Embase, and the Cochrane library from inception to September 2018 were systematically retrieved. The investigated outcomes included brachial-ankle pulse wave velocity (ba-PWV) and carotid-femoral PWV (cf-PWV) by using weighted mean differences (WMDs) and 95% confidence intervals (CIs) with the random-effects model. A total of 17 RCTs including 1,458 individuals were included. The summary results indicated no significant differences between ACEIs and control for ba-PWV and cf-PWV. Also, no significant differences between ACEI and control for ba-PWV and cf-PWV were observed in hypertensive patients, while the therapeutic effects of ACEI versus placebo showed statistically significant difference. Moreover, subgroup analysis indicated that the levels of ba-PWV were significantly associated if the study was conducted in Western countries, mean age <60.0 years, percentage male ≥60.0%, compared with ARBs, baseline PWV <10.0, and high-quality study. Furthermore, the significant levels of cf-PWV in patients who received ACEIs were observed when percentage male was ≥60.0% and the studies were of high-quality. Finally, no significant differences were observed between ACEIs and other antihypertensive drugs regarding the changes of systolic blood pressure (SBP) and diastolic blood pressure (DBP). The overall analysis suggested no significant differences between ACEIs and other antihypertensive drugs for ba-PWV and cf-PWV levels, whereas ACEIs versus placebo showed lower levels of ba-PWV and cf-PWV.

Abstract
The burden of cardiovascular diseases (CVD) is increasing, particularly in low-middle-income countries such as most of Latin America. This region presents specific socioeconomic characteristics, generating a high incidence of CVD despite efforts to control the problem. A consensus statement has been developed by Inter-American Society of Cardiology with the aim of answering some important questions related to CVD in this region and the role of the polypill in cardiovascular (CV) prevention as an intervention to address these issues. A multidisciplinary team composed of Latin American experts in the prevention of CVD was convened by the Inter-American Society of Cardiology and participated in the process and the formulation of statements. To characterize the prevailing situation in Latin American countries, we describe the most significant CV risk factors in the region. The barriers that impair the use of CV essential medications are also reviewed. The role of therapeutic adherence in CV prevention and how the polypill emerges as an effective strategy for optimizing adherence, accessibility, and affordability in the treatment of CVDs are discussed in detail. Clinical scenarios in which the polypill could represent an effective intervention in primary and secondary CV prevention are described. This initiative is expected to help professionals involved in the management of CVD and public health policymakers develop optimal strategies for the management of CVDs.

Abstract
INTRODUCTION The present study was conducted to directly compare the efficacy of running exercise and telmisartan treatment on angiotensin (Ang) II-mediated atherosclerosis and plaque vulnerability. MATERIALS AND METHODS Apolipoprotein E-deficient (ApoE-/-) mice with Ang II-mediated atherosclerosis (2-kidney, 1-clip [2K1C] renovascular hypertension model) were randomized into 3 groups: treadmill running exercise (RUN), telmisartan treatment (TEL), and sedentary untreated controls (SED) for 5 weeks. Atherosclerosis was assessed using histological and immunohistochemical analyses. Gene expression was determined by real-time reverse transcription polymerase chain reaction. RESULTS TEL but not RUN mice significantly decreased (50%) atherosclerotic lesion size compared to SED. RUN and TEL promoted plaque stabilization to a similar degree in ApoE-/- 2K1C mice. However, plaque composition and vascular inflammatory markers were differently affected: RUN decreased plaque macrophage infiltration (35%), whereas TEL reduced lipid core size (88%); RUN significantly increased aortic peroxisome proliferator-activated receptor (PPAR)-α, -δ, and -γ expression, whereas TEL significantly modulated T-helper 1/T-helper 2 (Th1/Th2) aortic response toward an anti-inflammatory state (decreased aortic interleukin [IL] 2 to IL-10 and IL-2 to IL-13 expression ratios). Plaque smooth muscle cell content was similarly increased (128% and 141%, respectively). Aortic AT1 and AT2 receptor expression as well as aortic CD11c/CD206 and IL-1β/IL-1ra expression ratios were not significantly modulated by either RUN or TEL. CONCLUSION Running exercise and telmisartan treatment are equally effective in preventing Ang II-mediated plaque vulnerability but through distinct cellular and molecular mechanisms. Our findings further support the use of exercise training and selective AT1 receptor blocker therapies for atherosclerotic cardiovascular disease prevention.

Abstract
Vitamin D receptor (VDR) agonists (VDRAs) are commonly used to manage hyperparathyroidism secondary to chronic kidney disease (CKD). Patients with CKD experience extremely high risks of cardiovascular morbidity and mortality. Clinical observations show that VDRA therapy may be associated with cardio-renal protective and survival benefits in patients with CKD. The 5/6 nephrectomized (NX) Sprague-Dawley rat with established uremia exhibits elevated serum parathyroid hormone (PTH), hypertension, and abnormal cardiac function. Treatment of 5/6 NX rats with VS-105, a novel VDRA (0.05 and 0.5 μg/kg po by gavage), once daily for 8 wk in the presence or absence of enalapril (30 mg/kg po via drinking water) effectively suppressed serum PTH without raising serum calcium. VS-105 alone reduced systolic blood pressure (from 174 ± 6 to 145 ± 9 mmHg, P < 0.05) as effectively as enalapril (from 174 ± 6 to 144 ± 7 mmHg, P < 0.05). VS-105 improved cardiac functional parameters such as E/A ratio, ejection fraction, and fractional shortening with or without enalapril. Enalapril or VS-105 alone significantly reduced left ventricular hypertrophy (LVH); VS-105 plus enalapril did not further reduce LVH. VS-105 significantly reduced both cardiac and renal fibrosis. The lack of hypercalcemic toxicity of VS-105 is due to its lack of effects on stimulating intestinal calcium transport and inducing the expression of intestinal calcium transporter genes such as Calb3 and TRPV6. These studies demonstrate that VS-105 is a novel VDRA that may provide cardiovascular benefits via VDR activation. Clinical studies are required to confirm the cardiovascular benefits of VS-105 in CKD.

High Blood Press Cardiovasc Prev 2014; 21:1-19.

Abstract
Hypertension is a frequent condition among individuals over 65 years of age worldwide and is one of the most important risk factors for cardiovascular (CV) disease. Effective drug treatment of elderly hypertensives is usually associated with a marked reduction in CV morbidity and mortality. Among the different classes of antihypertensive agents, angiotensin receptor blockers (ARBs) and ACE-inhibitors are supposed to provide the best efficacy in lowering blood pressure (BP) and protecting target organ damage while featuring a good tolerability profile. However, up to date, few randomized clinical studies have directly compared the activity and safety of ARBs and ACE-inhibitors in elderly hypertensive patients. Aim of this review of published and unpublished pooled data from two recent randomized, double-blind, controlled trials, is to offer a comprehensive head-to-head comparison of the antihypertensive efficacy of the ARB olmesartan medoxomil vs. the ACE-inhibitor ramipril in a large study population including more than 1,400 hypertensive subjects aged 65-89 years with mild-to-moderate essential hypertension. The efficacy of the two drugs was separately evaluated in subgroups of patients classified according to the presence of metabolic syndrome, reduced renal function, CV risk level, gender, class of age, type of arterial hypertension and previous antihypertensive treatments. Olmesartan showed a greater efficacy than ramipril both in terms of clinic BP reduction and rate normalization. Olmesartan appeared significantly superior to ramipril in providing a more homogeneous and long-lasting 24-h BP control and maintaining an effective antihypertensive action in the last 6-h period from drug intake. In subgroups of patients with additional clinical conditions, olmesartan gave comparable, and in some cases greater, BP responses than those achieved with the ACE-inhibitor. The incidence of adverse events was similar for both drugs. Olmesartan may thus represent an effective alternative to ACE-inhibitors among first-line drug treatments for hypertension in older people.

Abstract
Following its generation by both systemic and tissue-based renin-angiotensin systems, angiotensin II interacts with specific, G-protein coupled receptors to modulate multiple physiological systems, including the cardiovascular system. Genetic models in which the different components of the renin-angiotensin system have been deleted show large changes in resting blood pressure. Interruption of the generation of angiotensin II, or its interaction with these receptors, decreases blood pressure in hypertensive humans and experimental animal models of hypertension. Whilst the interaction of angiotensin II with the kidney is pivotal in this modulation of blood pressure, an involvement of the system in other tissues is important. Both systemic angiotensins, acting via the blood-brain barrier deficient circumventricular organs, and centrally-generated angiotensin modulate cardiovascular control by regulating fluid and electrolyte ingestion, autonomic activity and neuroendocrine function. This review discusses the pathways in the brain that are involved in this regulation of blood pressure as well as examining the sites in which altered angiotensin function might contribute to the development and maintenance of high blood pressure.

Abstract
OBJECTIVE To further develop and validate previously published national prescribing appropriateness criteria to assist in identifying drug-related problems (DRPs) for commonly occurring medications and medical conditions in older (≥65 years old) Australians. DESIGN RAND/UCLA appropriateness method. PARTICIPANTS A panel of medication management experts were identified consisting of geriatricians/pharmacologists, clinical pharmacists and disease management advisors to organisations that produce Australian evidence-based therapeutic publications. This resulted in a round-one panel of 15 members, and a round-two panel of 12 members. MAIN OUTCOME MEASURE Agreement on all criteria. RESULTS Forty-eight prescribing criteria were rated. In the first rating round via email, there was disagreement regarding 17 of the criteria according to median panel ratings. During a face-to-face second round meeting, discussion resulted in retention of 25 criteria after amendments, agreement for 14 criteria with no changes required and deletion of 9 criteria. Two new criteria were added, resulting in a final validated list of 41 prescribing appropriateness criteria. Agreement after round two was reached for all 41 criteria, measured by median panel ratings and the amount of dispersion of panel ratings, based on the interpercentile range. CONCLUSIONS A set of 41 Australian prescribing appropriateness criteria were validated by an expert panel. Use of these criteria, together with clinical judgement and other medication review processes such as patient interview, is intended to assist in improving patient care by efficiently detecting potential DRPs related to commonly occurring medicines and medical conditions in older Australians. These criteria may also contribute to the medication management education of healthcare professionals.
