Kammoun AK, Afify MA, Youssef RM, El-Nahass SA, Younis SE. Ecological assessment and development of analytical methods for concurrent quantification of valsartan and sacubitril: whiteness comparative study based on relative scoring. RSC Adv 2024; 14:16318-16326. [PMID: 38774613 PMCID: PMC11106649 DOI: 10.1039/d4ra01997k] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Accepted: 05/06/2024] [Indexed: 05/24/2024] Open
Abstract
Sustainable analytical chemistry is gaining great interest in global environmental pollution control. In addition, valsartan (VAS) and sacubitril (SAB) have been recently approved by the FDA as a fixed-dose combination "LCZ696". It showed efficacy and safety enough to extend its application from heart failure to hypertension control. VAS/SAB dual therapy is considered expensive; however, its prescription has increased significantly worldwide. This prescription increased the demand for developing sustainable analytical methods that simultaneously analyze VAS and SAB. Highly sensitive and selective spectrofluorimetric methods have been developed for this purpose. A synchronous spectrofluorimetric technique was applied. In one method, it was followed by spectral derivatization at the first-order level. The signals were recorded at 230 and 211 nm for VAS and SAB, respectively. Synchronous spectrofluorimetry was coupled to a dual-wavelength mathematical approach in the second method. Signals were derived by subtracting synchronous responses at 241 nm, 226 nm, and 239 nm from the response at 208 nm for VAS and SAB, respectively. Method validation was carried out following ICH guidelines. VAS showed linear calibration curves spanning the range of 60-200 and 80-600 ng mL-1 for the derivative and dual wavelength-assisted approaches, respectively. SAB achieved linear responses in the range of 17-190 and 30-350 ng mL-1 for the first and second methods, respectively. The green profile of the proposed methods was confirmed using the analytical eco-scale (AES), green analytical procedure index (GAPI), and analytical greenness metric (AGREE) tools. The proposed hybrid methods proved highly sustainable through the whiteness RGB 12 algorithm evaluation approach. Whiteness was comparatively assessed for the proposed and reported methods based on relative scoring depending on the parameters of each method. Despite this scoring approach being accurate as a relative score for comparative purposes, it gave rise to underestimated absolute scores. Therefore, to obtain a proper conclusion from the comparative whiteness study, all the methods were ranked according to their whiteness score, illustrating the excellent whiteness ranks of the proposed methods. Upon complete comparison with the reported methods, the suggested ones showed several advantages concerning analytical performance and the greenness level. The proven affordability and simplicity encourage their wide industrial application in developing countries.

Abstract
BACKGROUND LCZ696 is a novel neuroendocrine inhibitor that has been widely used in heart failure (HF). However, its advantage over other neuroendocrine inhibitors, such as angiotensin-converting enzyme inhibitors (ACEis) and angiotensin-receptor blockers (ARBs) has not been fully elucidated. This study aimed to provide the latest evidence regarding the efficacy and safety of LCZ696 as compared to other ACEis and ARBs with regards to the treatment of HF. METHODS We systematically searched databases, including PubMed, Embase, and the Cochrane Library, for relevant randomized controlled trials (RCTs). The outcome measures included all-cause mortality, rate of hospitalizations for HF, rate of death from cardiovascular causes, change in N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, and decline of renal function. RESULTS Five RCTs involving 19,078 patients were identified. The meta-analysis indicated that LCZ696 was associated with a significant reduction in all-cause mortality (hazard ratio [HR] = 0.84; 95% confidence interval [CI], 0.76-0.93; P = .0005), rate of hospitalizations for HF (HR = 0.80; 95% CI, 0.73-0.87; P < .00001), reduction in NT-proBNP levels (rate ratio = 0.78; 95% CI, 0.70-0.88; P < .0001), and decline in renal function (odds ratio = 0.77; 95% CI, 0.68-0.88; P < .0001) compared with ACEis and ARBs. However, there was no statistical difference in the rate of death from cardiovascular causes (HR = 0.86; 95% CI, 0.72-1.03; P = .09) between LCZ696 and ACEis and ARBs. CONCLUSION LCZ696 is superior to ACEis and ARBs in the treatment of HF. Hence, it should be more widely used clinically.

The Difference between Sacubitril Valsartan and Valsartan on Vascular Endothelial Function, APN, MMP-9, and BNP Levels in Patients with Hypertension and Chronic Heart Failure. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:9494981. [PMID: 35222898 PMCID: PMC8881145 DOI: 10.1155/2022/9494981] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 01/21/2022] [Indexed: 11/23/2022]
Abstract
Background Sacubitril valsartan and valsartan are the first new drugs approved for angiotensin receptor neprilysin lysine inhibitors (ARNIs) in outpatients with chronic heart failure (CHF) and hypertension. Compared with enalapril, sacubitril valsartan and valsartan have been shown to reduce the mortality and morbidity of cardiovascular diseases. However, there is little actual evidence regarding the efficacy of ARNIs in hypertensive patients with CHF. Methods From January 2019 to January 2021, 60 patients with hypertension and chronic heart failure were diagnosed and treated in our hospital. The patients were randomly divided into an observation group and a control group, with 30 cases in each group. The control group was given valsartan, the observation group was given sacubitril valsartan, and both groups were treated for six months. The endothelium-dependent vasodilation (EDD) function of the brachial artery and serum nitric oxide (NO), endothelin-1 (ET-1), carotid artery intima-media thickness, and glomerular filtration, excess rate (eGFR), and left ventricular ejection fraction (LVEF) were compared between the two groups of patients before and after treatment. The serum adiponectin (APN), matrix metalloproteinase-9 (MMP-9), and brain natriuretic peptide (BNP) levels were compared before and after treatment. Results The total effective rate of treatment in the research group was higher than that in the control group (P < 0.05). After treatment, the cardiac function indexes LVESD and LVEDD of the two groups of patients were lower than before treatment, and LVEF was higher than before treatment, and the improvement rate of the treatment group was better than that of the control group (P < 0.05). After treatment, the serum APN of the two groups was higher than before treatment, the levels of MMP-9 and BNP were lower than before treatment, and the improvement rate of patients in the treatment group was better than that of patients in the control group (P < 0.05). There was no statistically significant in the levels of EDD, NO, and ET-1 of the two groups of patients before treatment (P < 0.05). After treatment, compared with the control group, the EDD function and NO level of the research group were significantly increased (P < 0.05), and the level of ET-1 was significantly reduced (P < 0.05). There was no statistically significant difference in carotid artery intima-media thickness, glomerular filtration rate, and left ventricular ejection fraction before and after treatment in the two groups (P < 0.05). Conclusion In the treatment of hypertension and chronic heart failure, sacubitril valsartan can improve the clinical symptoms of patients to the greatest extent and can significantly improve the levels of LVEF, LVEDD, NT-proBNP, heart function, and other indicators. Sacubitril valsartan can increase serum APN levels, reduce MMP-9 and BNP levels, and have good clinical effects. Sacubitril valsartan has a protective effect on the vascular endothelial function of patients with hypertension and CHF. However, these results need to be confirmed in studies involving more subjects and require longer follow-up times.

Abstract
Chronic heart failure (CHF) leads to an excess of urgent ambulatory visits, recurrent hospital admissions, morbidity, and mortality regardless of medical and non-medical management of the disease. This excess of risk may be attributable, at least in part, to comorbid conditions influencing the development and progression of CHF. In this perspective, the authors examined and described the most common endocrine disorders observed in patients with CHF, particularly in individuals with reduced ejection fraction, aiming to qualify the risks, quantify the epidemiological burden and discuss about the potential role of endocrine treatment. Thyroid dysfunction is commonly observed in patients with CHF, and sometimes it could be the consequence of certain medications (e.g., amiodarone). Male and female hypogonadism may also coexist in this clinical context, contributing to deteriorating the prognosis of these patients. Furthermore, growth hormone deficiency may affect the development of adult myocardium and predispose to CHF. Limited recommendation suggests to screen endocrine disorders in CHF patients, but it could be interesting to evaluate possible endocrine dysfunction in this setting, especially when a high suspicion coexists. Data referring to long-term safety and effectiveness of endocrine treatments in patients with CHF are limited, and their impact on several "hard" endpoints (such as hospital admission, all-cause, and cardiovascular mortality) are still poorly understood.

Abstract
A hybrid Spectrofluorimetric method was developed for the simultaneous determination of binary mixtures, without prior separation steps. It coupled synchronous spectrofluorimetry with derivative ratio mathematical treatment. The method was applied successfully to quantify a new model binary mixture consisting of Valsartan (VAL) and Sacubitril (SAC). This mixture was recently approved by FDA as LCZ696. It added a great value in reducing morbidity and mortality in resistant heart failure (HF) patients. First derivative ratio synchronous fluorescence was measured at 258-295 (peak-to-peak) and 204 nm for VAL and SAC, respectively. ICH guidelines were fulfilled for the method validation. VAL and SAC showed linear responses in the range of 60-200 and 20-200 ng mL-1, respectively. The proposed method was compared, in details, with the reported ones. Its high accuracy, selectivity, simplicity and affordable cost recommend method application in large-scale routine analysis of LCZ696 tablets. Moreover, reliable application of this new integrated spectrofluorimetric method suggests expansion of its application for various therapeutic combinations and different matrices.

Abstract
BACKGROUND The mechanisms underlying angiotensin receptor-neprilysin inhibitor (ARNi) suppression of ventricular arrhythmia (VA) are unclear. This study aimed to investigate the mechanism of ARNi-related suppression of VA in a heart failure (HF) model. METHODS New Zealand white rabbits (n = 6 per group) were assigned to normal, HF [4 weeks of left ascending artery (LAD) ligation], angiotensin receptor blocker (ARB, valsartan at 27 mg/kg/day for 3 weeks after 1 week of LAD ligation), and ARNi (sacubitril at 34 mg/kg/day and valsartan at 27 mg/kg/day for 3 weeks after 1 week of LAD ligation) groups. Experiments involving echocardiogram, optical mapping, histological of trichrome stain and immunostain, and flow cytometry were performed. RESULTS HF group had larger left ventricular (LV) internal dimensions in diastole and systole, and lower LV ejection fraction and fractional shortening than normal, ARB, and ARNi groups. HF group had a prolonged action potential duration (APD) and decreased conduction velocity (CV), which was mitigated in ARB and ARNi groups. HF group had a prolonged QRS duration, QT and QTc intervals, which was reversed in ARB and ARNi groups. HF group had a steeper maximum slope of APD restitutions, which was attenuated in normal, ARB, and ARNi groups. HF group had increased number of phase singularities (PSs) and VA inducibility than normal, ARB, and ARNi groups. A higher content of fibrosis was found in HF group than that in normal, ARB, and ARNi groups. Compared to ARB group, ARNi had a lower context of fibrosis. HF group had more peripheral blood CD4+ and CD8+ cells count than normal, ARB, and ARNi group. CONCLUSIONS In a rabbit model of ischemic HF, ventricular arrhythmogenesis could be suppressed by ARNi treatment. This appears to be mediated by reversing changes in the APD, CV, maximum slope of the APDR, PSs, fibrosis, and inflammation.

Abstract
Objectives To systematically evaluate the differences in effect and safety of LCZ696 and angiotensin receptor blockers (ARBs) in the treatment of hypertension. Methods We searched PubMed, Cochrane, Web of Science, and Ovid, collected randomized controlled trials (RCTs) about the effect and safety of LCZ696 and ARBs in hypertensive patients, extracted relevant data and evaluated the quality of the included literature according to the RCT quality evaluation standard recommended by Cochrane Reviewer's Handbook, using RevMan 5.3, and performed meta-analysis. Results Eight RCTs studies were included, with a total of 4313 patients. Compared with ARBs, LCZ696 can better reduce systolic blood pressure (msSBP) (WMD −4.29 mmHg; 95% CI: −5.37 to −3.21; P < 0.001), diastolic blood pressure (msDBP) (WMD −1.87 mmHg; 95% CI:−2.38 to −1.36; P < 0.01), ambulatory systolic blood pressure (maSBP) (WMD −3.37 mmHg; 95% CI:−4.26 to −2.47; P < 0.01), and ambulatory diastolic blood pressure (maDBP) (WMD −1.47 mmHg; 95% CI: −1.97 to −0.97; P < 0.01). In terms of safety, LCZ696 is basically the same as ARBs, but LCZ696 is more likely to cause cough than ARBs (OR = 2.38; 95% CI: 1.27 to 4.47; P < 0.01). Conclusion LCZ696 can significantly reduce the blood pressure level of patients with hypertension, but it is necessary to pay attention to whether the patient will experience coughing after taking the drug.

Abstract
Aims Sacubitril‐valsartan has been shown to have superior effects over angiotensin‐converting enzyme inhibitors and angiotensin receptor blockers in patients with heart failure (HF) and hypertension. The efficacy and safety of sacubitril‐valsartan in patients with HF are controversial. We performed a meta‐analysis of randomized controlled trials to assess and compare the effect and adverse events of sacubitril‐valsartan, valsartan, and enalapril in patients with HF. Methods and results We conducted a systematic search using PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov. Randomized controlled trials involving the use of sacubitril‐valsartan in patients with HF were included. We assessed the pooled odds ratio (OR) of all‐cause mortality, cardiovascular mortality, and hospitalization for HF in fixed‐effects models and the pooled risk ratio (RR) of symptomatic hypotension, worsening renal function, and hyperkalaemia in fixed‐effects models. Of the 315 identified records, six studies involving 14 959 patients were eligible for inclusion. Sacubitril‐valsartan reduced the endpoints of all‐cause mortality and cardiovascular mortality in patients with HF with reduced ejection fraction (HFrEF) in three trials with pooled ORs of 0.83 (P = 0.0006) and 0.78 (P < 0.0001), respectively. Regarding the composite outcome of hospitalization for HF in five trials, the pooled OR was 0.79 (P < 0.00001). Compared with enalapril or valsartan, sacubitril‐valsartan was associated with a high risk of symptomatic hypotension (RR 1.47, P < 0.00001), low risk of worsening renal function (RR 0.81, P = 0.005), and low rate of serious hyperkalaemia (≥6.0 mmol/L) (RR 0.76, P = 0.0007) in all six trials. Conclusions Compared with angiotensin‐converting enzyme inhibitors or angiotensin receptor blockers, sacubitril‐valsartan significantly decreased the risk of death from all causes or cardiovascular causes in HFrEF and hospitalization for HF in both patients with HFrEF and HF with preserved ejection fraction. Sacubitril‐valsartan reduced the risk of renal dysfunction and serious hyperkalaemia but was associated with more symptomatic hypotension.

Abstract
Assessment of kidney function is primarily based on urine output and Creatinine (Cr)-based methods to estimate glomerular filtration rate (GFR). The latter is confounded as Cr is not exclusively filtered by the kidney and rises relatively late after the onset of acute kidney injury (AKI). This leads to delays in recognition of reduced kidney function and diagnosis of AKI, particularly in critically ill patients where kidney function can change rapidly. The gold standard methods of GFR determination, such as inulin or iohexol clearance, are labor intensive and unfeasible in acute clinical settings. Proenkephalin A 119-159 (PENK) has been intensively studied as a novel biomarker of kidney function. PENK belongs to the enkephalin peptide family and is freely filtrated in the glomerulus. Plasma PENK concentration appears to correlate strongly with GFR. Moreover, increased plasma PENK concentrations are found to be associated with long-term kidney outcomes and mortality. In this review, we summarize the role of PENK in assessment of kidney function and its capacity to predict various clinical outcomes.

Effect of Sacubitril-Valsartan in reducing depression in patients with advanced heart failure. J Affect Disord 2020; 272:132-137. [PMID: 32379604 DOI: 10.1016/j.jad.2020.03.158] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 02/18/2020] [Accepted: 03/29/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Depression is highly prevalent in Heart Failure (HF). Treatment with sacubitril/valsartan improved quality of life and survival in HF patients. Aim of the study was to investigate prospectively the effect of sacubitril/valsartan on depression in advanced HF patients in waiting list for heart transplant (HT). METHODS 37 consecutive patients with advanced HF in waiting list for HT were treated with sacubitril/valsartan. We analyzed data derived from the assessment performed the year before the beginning of sacubitril/valsartan, at study entry, and at one year of follow-up. Depression was assessed with Beck Depression Inventory II (BDI) scale. Cognitive function were assessed with Mini-Mental State Examination (MMSE). Functioning was evaluated measuring meters at 6 Minute Walking Test (6MWT) and maximum rate of oxygen consumption (VO2 max). RESULTS At baseline, 64.9% of HF patients were in NYHA III and 35.1% NYHA IIIB, BDI was 15.2 ± 5.2 with 59.5% of patients with a score > 13. MMSE was 27.8 ± 2.6. After one year of follow-up NYHA class improved significantly, with 56.8% in NYHA II, 40.5% in NYHA III and 2.7% NYHA in IIIB (p < 0.001). VO2 max and 6MWT increased. Notably, BDI was 9.5 ± 3.9 with 21.6% of patients with a score > 13. MMSE remain stable (28.2 ± 2.1) (p = 0.104). No statistical differences are observed between data collected in the evaluation 1-year before and soon before treatment with sacubitril/valsartan. Multivariate regression analysis demonstrate a relationship between reduction in BDI-II score and improvement in six-minute walking test independently by the effect of sex, age, selective serotonin reuptake inhibitors, VO2 max, NT-proBNP, PAPs, NYHA class differences evaluated at follow-up versus baseline. CONCLUSIONS Our study showed a reduction in depressive symptomatology in heart transplant waiting list patients treated with sacubitril/valsartan. The improvement in depressive symptomatology was paralleled by 6MWT increase in the follow-up.

Abstract
Arterial hypertension is the most prevalent chronic disease in the adult population of developed countries and it constitutes a significant risk factor in the development of cardiovascular disease, contributing to the emergence of many comorbidities, among which heart failure excels, a clinical syndrome that nowadays represents a major health problem with uncountable hospitalizations and the indolent course of which progressively worsens until quality of life decreases and lastly death occurs prematurely. In the light of this growing menace, each day more efforts are invested in the field of cardiovascular pharmacology, searching for new therapeutic options that allow us to modulate the physiological systems that appear among these pathologies. Therefore, in the later years, the study of natriuretic peptides has become so relevant, which mediate beneficial effects at the cardiovascular level such as diuresis, natriuresis, and decreasing cardiac remodeling; their metabolism is mediated by neprilysin, a metalloproteinase, widely expressed in the human and capable of catalyzing many substrates. The modulation of these functions has been studied by decades, giving room to Sacubitril, the first neprilysin inhibitor, which in conjunction with an angiotensin receptor blocker has provided a high efficacy and tolerability among patients with heart failure, for whom it has already been approved and recommended. Nonetheless, in the matter of arterial hypertension, significant findings have arisen that demonstrate the potential role that it will play among the pharmacological alternatives in the upcoming years.

Abstract
AbstractThe active pharmaceutical ingredient sacubitril acts as a neprilysin inhibitor in the body and is administered to patients suffering from high blood pressure and chronic heart failure. In this paper, we report the development of a three-step setup for the synthesis of an advanced sacubitril precursor in continuous flow. The key transformation of our cascade is a Suzuki-Miyaura coupling facilitated by a heterogeneous palladium catalyst. Its implementation in a packed-bed reactor and the application of continuous flow methodologies allow intensification of the cross-coupling reaction compared to batch processing. The subsequent steps for the synthesis of the target molecule involve Boc-deprotection as well as N-succinylation, which have been optimized using the statistical “Design of Experiments” (DoE) approach. In this way, the individual as well as interactive effects of selected parameters on the output of the reactions could be investigated very efficiently. The consecutive performance of the three reaction steps using an integrated setup enabled the synthesis of a late-stage sacubitril precursor in continuous flow with 81% overall yield.

Abstract
After millennia of knowledge of opium, it was only recently that endogenous substances called opioids with similar properties to opium and derivatives were discovered. The first to be discovered were enkephalins. In addition to the regulation of their synthesis and expression of receptors, an important mechanism for the regulation of their functions carried out by multiple proteolytic enzymes acting at all levels of their structure is described. The action of such enzymes, known as enkephalinases, is also regulated by endogenous and exogenous factors which ultimately affect the control of the enkephalins's action. For therapeutic purposes, it is not only necessary to develop specific inhibitors but also to acquire a deep knowledge of the influence that such factors exert on their activities. This knowledge could help us to establish adapted therapeutic strategies in the treatment of pain or other processes in which enkephalinases are involved. In this chapter, some of these regulatory factors are discussed, such as regional and subcellular distribution, developmental changes, diurnal variations, hormonal influences, stress, dietary factors or interactions with other neurotransmitters.

Abstract
INTRODUCTION The efficacy and safety of sacubitril/valsartan used as an antihypertensive agent has not yet been completely assessed. Thus, to investigate them in elderly hypertensive patients, a meta-analysis has been performed. EVIDENCE ACQUISITION The meta-analysis incorporated only randomized controlled trials (RCTs) in which sacubitril/valsartan was compared with a reference drug. The mean reductions in systolic blood pressure (msSBP) and diastolic blood pressure (msDBP) in the sitting position as well as the mean reductions in ambulatory systolic blood pressure (maSBP) and ambulatory diastolic blood pressure (maDBP), were assumed as efficacy endpoints. Adverse events were taken as safety outcomes. EVIDENCE SYNTHESIS Five RCTs were included for a total of 1513 patients for analysis. In all studies, the comparator drug was an angiotensin receptor blocker (ARB) - valsartan in two cases and olmesartan in the remaining three cases. Compared with ARBs, there was a significant reduction in msSBP (weight mean difference [WMD] -5.41 mmHg, 95% CI: -7.0 to -3.8; P<0.01), msDBP (WMD=-1.22 mmHg, 95% CI: -2.15 to -0.3; P<0.01), maSBP (WMD=-4.58 mmHg, 95% CI: -5.62 to -3.54; P<0.01) and maDBP (WMD=-2.17 mmHg, 95% CI: - 2.78 to -1.56; P<0.01) in elderly hypertensive patients at 12 weeks. CONCLUSIONS Sacubitril/valsartan may reduce arterial pressure more efficaciously than ARBs in elderly hypertensive patients.

Abstract
BACKGROUND Hypertension is a major cause of death and morbidity worldwide and is increasing in prevalence. The Renin-angiotensin system (RAS) is the most common mechanism involved in the pathophysiology of hypertension. Understanding the mechanism of the pathophysiologic processes will help direct potential therapeutic strategies to treat hypertension and improve cardiac function. Recently, a novel drug LCZ696 containing both an angiotensin receptor blocker valsartan and a neprilysin inhibitor (AHU377) has shown a promising effect on the treatment of hypertension. However, the effects of LCZ696 on the expression of main components of RAS, namely, angiotensin-converting enzyme (ACE), angiotensin-converting enzyme 2 (ACE2), angiotensin II type 1 receptor (AT1 R), angiotensin II type 2 receptor (AT2 R), and angiotensin (1-7) receptor/Mas receptor (MasR) remain unclear. The aim of the present study was to evaluate the effects of LCZ696 on the protective arms of RAS in the cardiac tissue when compared with valsartan under the equal inhibition of AT1 R. We hypothesized that the superior effects of LCZ696 may contribute to its greater effect on the RAS than valsartan. MATERIALS AND METHODS Sixteen-week-old female spontaneously hypertensive rats (SHRs) were used in this study. Wistar-Kyoto (WKY) rats were used as controls. All rats were randomly divided into LCZ696 (n = 10), valsartan (n = 10), SHR (n = 10), and WKY (n = 10) groups under a 12-hour dark and 12-hour light cycle and provided with regular chow diet and water. The tail-cuff method was performed to measure blood pressure. Cardiac function was assessed by echocardiography. RESULTS The blood pressure value was lower in LCZ696 than valsartan in SHR after 12 weeks of treatment. Further, LCZ696 inhibits the ACE and AT1 R protein expression in the cardiac of SHR and significantly upregulate the protective axis of RAS components, including ACE2, MasR, and AT2 R. Left ventricular AT2 R messenger RNA (mRNA) expression was higher in the LCZ696+SHR group compared with valsartan. In addition, real-time polymerase chain reaction analysis revealed that LCZ696 enhanced the mRNA expression of antihypertensive components AT2 R, ACE2, and MasR and decreased the expression of AT1 R. However, only AT2 R and ACE2 mRNA expressions have a statistical difference between the LCZ696 and valsartan groups. No difference was observed in the mRNA expression of ACE and MasR. The stronger positive signal of transforming growth factor β in the left ventricle was inhibited in each administrated group compared with SHR groups. CONCLUSIONS LCZ696 ameliorates the vasoconstrictor axis of the RAS AT1 R and stimulate the protective arm effectors, ACE2 and AT2 R, as well as reverses the compensatory upregulation of neuronal nitric oxide synthase and endothelial nitric oxide synthase in SHR. These findings suggest the mechanistic insight of the cardiac-protective and greater hypotensive effects of LCZ696.

Abstract
Background For elderly patients suffering from arterial hypertension, a complete assessment of the efficacy and safety of sacubitril/valsartan used as an anti-hypertensive agent is not available yet. Therefore, we decided to perform a meta-analysis of randomized controlled trials (RCTs) to explore some endpoints concerning anti-hypertensive efficacy as well as safety of sacubitril/valsartan in elderly hypertensive patients. Methods PubMed and Scopus have been extensively investigated with the help of some key words until June 15, 2018. The meta-analysis incorporated exclusively RCTs in which the anti-hypertensive efficacy and safety of sacubitril/valsartan were compared with those of a reference drug (comparator) that could be an angiotensin-converting enzyme inhibitor (ACEi), an angiotensin receptor blocker (ARB), a calcium channel blocker (CCB) or a beta-blocker. Continuous ambulatory blood pressure monitoring was required as an inclusion criterion in the studies to be included in the meta-analysis. The mean reductions in systolic blood pressure and diastolic blood pressure in the sitting position (msSBP and msDBP, respectively), as well as the mean reductions in ambulatory systolic blood pressure (maSBP) and ambulatory diastolic blood pressure (maDBP), were assumed as efficacy endpoints. Adverse events (AEs) were taken as safety outcomes. Results Five RCTs were included with a total of 1,513 patients for analysis. In all studies, the comparator drug was an ARB (valsartan in two cases and olmesartan in the remaining three cases). Compared with ARBs, after 12 weeks there was a significant reduction in msSBP (weight mean difference (WMD) = - 5.41 mm Hg, 95% confidence interval (CI): -7.0 to -3.8; P < 0.01), msDBP (WMD = -1.22 mm Hg, 95% CI : -2.15 to -0.3; P < 0.01), maSBP (WMD = -4.58 mm Hg, 95% CI: -5.62 to -3.54; P < 0.01) and maDBP (WMD = -2.17 mm Hg, 95% CI: - 2.78 to -1.56; P < 0.01) in elderly hypertensive patients at 12 weeks. Conclusions Sacubitril/valsartan may reduce arterial pressure more efficaciously than ARBs in elderly hypertensive patients. These results have to be confirmed by further RCTs with a good methodological quality, possibly with a greater sample size.

Abstract
The common ultimate pathological feature for all cardiovascular diseases, congestive heart failure (CHF), is now considered as one of the main public health burdens that is associated with grave implications. Neurohormonal systems play a critical role in cardiovascular homeostasis, pathophysiology, and cardiovascular diseases. Hormone treatments such as the newly invented dual-acting drug valsartan/sacubitril are promising candidates for CHF, in addition to the conventional medications encompassing beta receptor blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor antagonists. Clinical trials also indicate that in CHF patients with low insulin-like growth factor-1 or low thyroid hormone levels, supplemental treatment with growth hormone or thyroid hormone seems to be cardioprotective; and in CHF patients with volume overload the vasopressin antagonists can relieve the symptoms superior to loop diuretics. Furthermore, a combination of selective glucocorticoid receptor agonist and mineralocorticoid receptor antagonist may be used in patients with diuretic resistance. Finally, the potential cardiovascular efficacy and safety of incretin-based therapies, testosterone or estrogen supplementation needs to be prudently evaluated in large-scale clinical studies. In this review, we briefly discuss the therapeutic effects of several key hormones in CHF.

Abstract
BACKGROUND Endogenous opioids, enkephalins, are known to increase with acute kidney injury. Since the mature pentapeptides are unstable, we evaluated the performance of an assay that measures proenkephalin 119-159 (PENK), a stable peptide formed concomitantly with mature enkephalins. METHODS PENK assay performance was evaluated on two microtiterplate/chemiluminescence sandwich immunoassay formats that required 18 or 1 h incubation times. PENK concentration was measured in plasma from healthy individuals to establish a reference interval and in patients with varied levels of kidney function and comorbidities to assess the association with measured glomerular filtration rate (mGFR) using iothalamate clearance. RESULTS Assay performance characteristics in plasma were similar between the assay formats. Limit of quantitation was 26.0 pmol/L (CV = 20%) for the 1 h assay and 17.3 pmol/L (CV = 3%) for the 18 h assay. Measurable ranges were 26-1540 pmol/L (1 h assay) and 18-2300 pmol/L (18 h assay). PENK concentrations are stable in plasma stored ambient to 10 days, refrigerated to at least 15 days, and frozen to at least 90 days. Results were comparable in paired SST serum and EDTA plasma. Age and sex were not associated with PENK concentrations in healthy individuals (reference interval: 36-97.5 pmol/L). Plasma PENK concentration correlated with mGFR. In a multivariate model PENK concentration, age, sex and transplant status were significant predictors of mGFR, and 49% of predicted GFR values fell within 30% of the mGFR. CONCLUSIONS Both assay formats are accurate and precise for measuring clinically relevant PENK concentrations. The association of PENK concentration with mGFR is influenced by gender, age, and history of kidney transplantation. Future studies will determine if blood PENK can be used clinically to estimate GFR and/or detect AKI.

Abstract
Peptides, such as C-type natriuretic peptide (CNP), vasoactive intestinal polypeptide (VIP) and endothelin 1 (ET-1), are involved in the control of penile erectile tissue (corpus cavernosum = CC). Inhibiting the degradation of CNP and VIP or conversion of Big ET-1 into ET-1 by endopeptidase enzymes should result in an enhancement of CC smooth muscle relaxation. Using the tissue bath technique, responses of isolated CC, challenged by noradrenaline (NA, 1 μm), to increasing concentrations of the endopeptidase inhibitor KC 12615 (1 nm - 10 μm), CNP and VIP (0.1 nm - 1 μm), were investigated. Effects of CNP, VIP and Big ET-1 (0.1 nm - 100 nm) on the tissue tension were also evaluated following pre-exposure to 10 μm of KC 12615. Big ET-1 induced contraction of the CC amounting to a force generation of 1,200 mg. The contraction was attenuated in the presence of KC 12615 by 35% and 50%, respectively. The tension induced by NA was reversed by VIP and CNP to 38.7% ± 15.8% and 61% ± 13%, respectively, of the initial force. The findings might be of significance with regard to future pharmacological treatment options for male ED, where an endothelial dysfunction exists.

Abstract
The treatment of thyroid cancer has promising prospects, mostly through the use of surgical or radioactive iodine therapy. However, some thyroid cancers, such as progressive radioactive iodine-refractory differentiated thyroid carcinoma, are not remediable with conventional types of treatment. In these cases, a treatment regimen with multi-kinase inhibitors is advisable. Unfortunately, clinical trials have shown a large number of patients, treated with multi-kinase inhibitors, being adversely affected by hypertension. This means that treatment of thyroid cancer with multi-kinase inhibitors prolongs progression-free and overall survival of patients, but a large number of patients experience hypertension as an adverse effect of the treatment. Whether the prolonged lifetime is sufficient to develop sequelae from hypertension is unclear, but late-stage cancer patients often have additional diseases, which can be complicated by the presence of hypertension. Since the exact mechanisms of the rise of hypertension in these patients are still unknown, the only available strategy is treating the symptoms. More studies determining the pathogenesis of hypertension as a side effect to cancer treatment as well as outcomes of dose management of cancer drugs are necessary to improve future therapy options for hypertension as an adverse effect to cancer therapy with multi-kinase inhibitors.

Abstract
Hypertensive heart diseases affect millions of people worldwide. We aimed to investigate the hypertensive left ventricular histological changes and assess the effectiveness of bone marrow derived mesenchymal stem cells (MSCs) therapy in the treatment of hypertensive cardiomyopathy. Adult male albino rats were assigned into two groups: group I (control), group II (Experimental) subdivided into subgroup IIa (hypertensive) and subgroup IIb (stem cell therapy). Left ventricles (LVs) were processed for light and electron microscope. Mallory's trichrome and immunostaining for caspase-3 and desmin were carried out. Hypertension caused left ventricular histological and immunohistochemical changes that had been effectively improved by MSCs therapy.
