Screening of serum markers in patients with resistant hypertension

BackgroundThis study delves into the intricacies of resistant hypertension (RH), a prevalent yet enigmatic chronic cardiovascular ailment that is linked to a myriad of complications. Although its full pathogenesis is still shrouded in mystery, the field of proteomics offers a beacon of hope, with its potential to shed light on the proteins that orchestrate the tapestry of life. Harnessing the power of proteomics is essential for demystifying the pathogenesis of RH, enabling more precise diagnostics and treatments, and ultimately improving prognostic outcomes. MethodsOur approach was to employ rigorous statistical analyses to home in on proteins with significant expression variances between our two cohorts. We complemented this with bioinformatics tools to unravel the intricate functions and pathways of these proteins. By synthesizing these insights with the clinical profiles of our patients, we were able to distill a set of definitive biomarkers with diagnostic potential. In our quest for clarity, we also embarked on a retrospective journey, amassing and scrutinizing clinical data from both RH and hypertension (HTN) patients. We crafted and rigorously assessed risk factor models to evaluate their diagnostic prowess. ResultsOur exploration spanned across 30 blood samples from RH patients and 20 from those grappling with HTN. Our inquiry yielded some compelling revelations: (1) RH patients showcased 29 unique proteins, in contrast to the 59 unique proteins found in HTN patients. A deeper dive into the proteomic data unveiled molecular functions predominantly tied to lipid metabolism, protein networking, and oxidative stress, with a spotlight on pathways such as cholesterol metabolism, coagulation, and the complement cascade. (2) By charting receiver operating characteristic curves and rigorously analyzing the proteomic data, we surfaced 11 proteins with notable diagnostic potential, tightly interwoven with clinical metrics. ConclusionOur research has pinpointed 11 proteins that stand as promising serum biomarkers, endowed with significant diagnostic value. This discovery marks a stride towards a more nuanced understanding and management of resistant hypertension.

A review of novel endothelin antagonists and overview of non-steroidal mineralocorticoid antagonists for treating resistant hypertension: An update

Several agents are emerging from five different novel classes of antihypertensive medications. We will focus on endothelin antagonists and non-steroidal mineralocorticoid receptor antagonists. While several agents exist in this later class, only a couple have demonstrated superior efficacy in resistant hypertension management. Endothelin receptor antagonists are effective therapy for primary and resistant hypertension, but they are not widely used. This is due to side effects demonstrated in large clinical trials, specifically increased peripheral edema and worsening heart failure in some cases, as well as the availability of many alternative agents to manage blood pressure effectively. However, the relationship between endothelin and its close ties to hypertension is evolving. Recent pre-clinical work explores new applications of more selective endothelin receptor antagonists. They suggest that specific subtypes of hypertension may benefit more from endothelin receptor blockade than simply those with primary hypertension. We review this topic and other related data. Lastly, we also provide a brief overview of non-steroidal mineralocorticoid receptor antagonists as some in the class show promise as antihypertensive agents.

Recent developments in the management of resistant hypertension: focus on endothelin receptor antagonists.

Resistant hypertension is characterized by the inability of guideline-recommended triple combination therapy to control blood pressure(BP) to target. It is associated with a significantly increased risk of adverse outcomes. Despite abundant preclinical evidence supporting thecritical role of the endothelin pathway in resistant hypertension (RH), clinical implementation of endothelin antagonists for the treatment of hypertension was hindered by various factors. Recently, the novel dual endothelin-receptor antagonist aprocitentan was tested in individuals with resistant hypertension in the PRECISION trial and provided compelling evidence supporting both short and longer-term safety and clinically meaningful and sustained BP lowering efficacy.These findings resulted in therecent regulatory approval of aprocitentanby the FDA. Aprocitentan may be a particularly useful antihypertensive option for individuals with advanced age, chronic kidney disease, and albuminuria.

Spironolactone versus Eplerenone in Patients with Resistant Hypertension: A Systematic Review and Indirect Meta-analysis

Background: Spironolactone and eplerenone, both mineralocorticoid receptor antagonists (MRAs), have been shown to be effective in the management of resistant hypertension (RH), although there is a lack of randomised controlled trials (RCTs) that directly comparing the two. This systematic review and indirect meta-analysis compares the two MRAs and their effectiveness in lowering blood pressure (BP) in patients with RH. Methods: RCTs comparing eplerenone or spironolactone with a placebo in RH patients were included in the review. The primary outcome was the mean difference (MD) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). The secondary outcome was the MD of serum potassium levels. The pooled estimates of mean BP and mean potassium level difference were then analysed to attain the adjusted indirect comparisons. Results: Six RCTs involving 665 patients were included in the systematic review. The pooled MD of systolic and diastolic BP between eplerenone and placebo showed a reduction of −0.38 (p=0.0007) and −4.45 (p<0.0001), respectively. The pooled MD of systolic and diastolic BP between spironolactone and placebo showed a reduction of −4.82 (p=0.01) and −2.31 (p=0.006), respectively. The pooled MD of serum potassium levels between eplerenone and placebo as well as spironolactone and placebo was 0.16 (p=0.39) and −0.08 (p=0.59), respectively. An indirect comparison meta-analyses of the MD in systolic and diastolic BP (systolic MD 1.66; 95% CI [−3.46–6.78]; p=0.5250 and diastolic MD 2.14; 95% Cl [−0.63–4.91]; p=0.1293) as well as mean serum potassium levels (MD 0.24; 95% Cl, [−0.23–0.71]; p=0.313) between spironolactone and eplerenone, showed no significant difference. Conclusion: Spironolactone and eplerenone showed an equal reduction in systolic and diastolic BP, as well as serum potassium levels in patients with RH.

Controversies related to renal artery denervation and devices.

This review article discusses the controversies, strengths, and limitations of the current literature on renal artery denervation in the management of resistant hypertension, as well as the future directions of this intervention. There have been conflicting data from the different randomized control trials assessing the efficacy of renal artery denervation in the management of resistant hypertension. Renal artery denervation is achieved by ablating the sympathetic nerves surrounding the renal arteries using endovascular ultrasound, radiofrequency, or alcohol. Our review article highlights that renal artery denervation is generally effective in improving blood pressure in patients with resistant hypertension. The Food and Drug Administration (FDA) has recently approved the ReCor Medical Paradise system, and the Symplicity Spyral RDN systems for renal artery denervation.

Resistant hypertension.

Resistant hypertension (RH) is characterized by persistently elevated blood pressure despite the concurrent use of three antihypertensive medications, including a diuretic, at optimal doses. This clinical phenomenon poses a significant burden on healthcare systems worldwide due to its association with increased cardiovascular disease morbidity and mortality. Ongoing studies on device-based treatment of RH, with aim to reduce sympathetic nervous system outflow, have shown promising evidence in management of RH which may in turn decrease the incidence of composite cardiovascular outcome faced by the affected population. This paper aims to provide a comprehensive overview of RH, and review some of the diagnostic and therapeutic approaches in management of RH.

Resistant hypertension: challenges in everyday practice.

Resistant hypertension is defined as not achieving sufficient control of blood pressure (BP), that is, maintaining BP values equal to or above 140/90 mm Hg when using 3 antihypertensive drugs, including diuretics, properly combined and at maximum doses. The uncontrolled treated hypertension should be confirmed in out‑of‑office BP measurements, preferably with 24‑hour ambulatory BP monitoring. Demographic and clinical characteristics indicate that patients with resistant hypertension are older than the general population of patients with arterial hypertension and more often suffer from comorbidities. When resistant hypertension is suspected, it is necessary to assess whether optimal pharmacotherapy has been prescribed, including appropriate combinations of antihypertensive drugs and diuretics at appropriate doses. It is also important to exclude parallel use of drugs that may have unfavorable interactions leading to an increase in BP. A common cause of pseudoresistant hypertension is a patient's failure to comply with therapeutic recommendations, including a lack of lifestyle changes and nonadherence to the prescribed medication regimen. An important step in management of resistant hypertension is targeted screening with diagnostic tests for secondary hypertension. Expanding of the drug therapy beyond a 3‑drug regimen should include a mineralocorticoid receptor antagonist, in particular spironolactone. In selected patients, device‑based hypertension treatment might be considered.

Management of Resistant Hypertension.

Resistant hypertension (RH) is a severe form of hypertension associated with increased cardiovascular risk. Although true RH affects less than 10% of the patients receiving antihypertensive therapy, the absolute number is high and continues to increase. The workup of these patients requires screening for secondary hypertension and pseudoresistance, including poor adherence to prescribed medicines and the white-coat phenomenon. The treatment of RH consists of lifestyle modifications and pharmacological therapies. Lifestyle modifications include dietary adjustments, weight loss, physical activity, and limiting alcohol consumption; pharmacological therapies include diuretics, mineralocorticoid receptor antagonists, beta blockers, angiotensin receptor-neprilysin inhibitors, and others. Over the last 15 years, interventional approaches have emerged as adjunct treatment options; we highlight catheter-based renal denervation. This review summarizes the rationales and latest clinical evidence and, based thereon, proposes an updated algorithm for the management of RH.

The Implementation of Renal Denervation in the Management of Resistant Hypertension Despite Use of Multitherapy Antihypertensives at Maximally Tolerated Doses: A Contemporary Literature Review.

Refractory hypertension is highly prevalent among the hypertensive population, and current clinical management has failed to provide optimal control for these individuals. This subtype of arterial hypertension is defined as a persistently elevated systolic blood pressure reading of 140 mmHg, or higher, despite multiple antihypertensive use at maximally tolerated dosing. These patients have an elevated risk of cardiovascular and renal complications, urging for the need of more effective therapeutic management. Renal sympathetic efferent nerves have been noted to play an important role in volume and blood pressure homeostasis. Before the implementation of oral antihypertensives, the use of surgical lumbar sympathectomy for the reduction of persistent hypertension was considered a life-saving approach. However, individuals were left with debilitating side effects, such as postural hypotension, syncope, and impotence. A new and minimally invasive technique has been proposed, where the kidneys undergo selective denervation in hopes of providing decreased cardiovascular morbidity and mortality for patients with resistant hypertension. Some studies demonstrated promising outcomes with a reduction in blood pressure, a decrease in medication reliance, and a potential long-lasting effect of the procedure with an overall improvement in cardiovascular health. Unfortunately, most of the available data was obtained from observational, uncontrolled studies with short-term follow-up, small sample sizes, and high variability in blood pressure measurement. Therefore, further evidence is needed to determine whether renal denervation provides long-term benefits for blood pressure control and improves outcomes for mortality and cardiovascular events in this patient population.

A case study on management of resistant hypertension and reduction of serum creatinine in a Chronic Kidney Disease patient through Vajedi Basti

Kidney diseases are prevalent due to changing life style, improper eating habits, hypertension and uncontrolled diabetes. According to modern science, the treatment for chronic kidney failure is haemodialysis or kidney transplant, both are quite expensive. Ayurveda plays an important role for finding effective and safe medicines to prevent kidney failure. A 38-year-old male patient diagnosed with Chronic Kidney Disease (CKD) and uncontrolled Hypertension (HTN) on three anti-hypertensive agents attended the OPD of Sane Guruji Arogya Kendra, Malwadi, Hadapsar Pune. The patient was initially kept on oral ayurvedic treatment for ten days. Then he was subjected to Basti Karma along with Sthanik Snehana-Swedana. After this therapy which continued for 21 days, it was found that the baseline blood pressure (180/110 mmHg) came down to 140/90 mmHg in the third week and serum creatin level ratio also reduced gradually. This therapy was provided along with allopathic medication as prescribed and patient was advised to continue allopathic medicine and to monitor BP regularly. After another 180 days monitoring, the patient had normal blood pressure along with a reduction in serum creatinine levels. From the results, it is concluded that this procedure is useful in resistant hypertension (RH), reducing the creatine level and in stabilizing and maintaining the blood pressure in a long run. Further study is recommended.

Eplerenone add-on treatment in resistant hypertension in peritoneal dialysis patient. A case report

Resistant hypertension (RH) is frequently seen in clinical practice in kidney disease patients. Mineralocorticoid receptor antagonists (MRAs) especially spironolactone are highly effective in the management of RH. Eplerenone — highly selective MRA has been also shown to be effective in RH patients but it is rarely used in this clinical condition, especially in kidney disease patients. Eplerenone is mainly recommended in congestive heart failure after myocardial infarction. A case of peritoneal dialysis (PD) patient with RH successfully treated with eplerenone was reported.

Novel Dual Endothelin Inhibitors in the Management of Resistant Hypertension

Resistant hypertension (RH) is defined as the failure to achieve blood pressure control despite using triple combination therapy with a renin-angiotensin system inhibitor (RAS-i), a calcium antagonist, and a diuretic. The endothelin (ET) system is implicated in the regulation of vascular tone, primarily through vasoconstriction, intervenes in cardiac contractility with inotropic effects, and contributes to water and sodium renal reabsorption. ET inhibitors, currently approved for the treatment of pulmonary hypertension, seem to be also useful for essential hypertension and RH as well. Studies into the development of new dual ET inhibitors, which inhibit both type A and B ET (ETA and ETB) receptors, present initial results of managing RH. Aprocitentan (ACT-132577) is a novel, orally active and well tolerated dual ET receptor antagonist, which has been examined in several experimental studies and clinical trials with promising results for RH control. The recent publication of the large PRECISION study in The Lancet journal provides further reassurance regarding the efficacy and safety of aprocitentan for RH, with the aim of overcoming unmet needs in the management of this difficult group of patients.

Resistant hypertension: integrated strategies between pharmacological treatment and renal denervation

The achievement of adequate blood pressure (BP) control and the management of resistant hypertension still represent two burning "unmet needs" in the field of cardiovascular diseases, thus originating a continuous search for more efficacious pharmacological and non-pharmacological strategies including radiofrequency and ultrasound renal denervation (RDN). The most recent guidelines recommend a combination therapy of two or more antihypertensive agents, preferably in a single-pill formulation, as first-line strategy to achieve an effective and early BP control also improving adherence to prescribed treatments. In the last few years several sham-controlled trials have confirmed both the BP-lowering efficacy and safety of RDN in a broad range of patients with hypertension, showing a significant reduction of office and ambulatory BP levels without a relevant increase of procedure-related adverse events such as renal artery stenosis and worsening renal function. These results have been recently confirmed by the analyses of 3-year follow-up data. According to these findings, RDN may represent a useful tool in addition to pharmacological treatment with more compelling indications for patients with resistant hypertension, those who are non-adherent or intolerant to multiple antihypertensive drugs or express a preference to undergo RDN. Further studies are necessary to explore the efficacy of RDN on prevention of hypertension-mediated organ damage and reduction of major cardiovascular events.

Back to Life Treatment of Resistant Hypertension- An Update

Resistant hypertension is characterized by severe and persistent high blood pressure that is not normalized even after administering two or more antihypertensive medications, of which one is a diuretic. Although resistant hypertension is commonly encountered in clinics, the prognosis is largely unclear. Mounting evidence indicate that resistant hypertension is a multifactorial pathology of diverse etiology. A wide variety of predisposed factors including age, ethnicity, obesity, obstructive sleep apnea, primary aldosteronism, chronic kidney disease, excessive sympathetic activation and baroreflex dysfunction may be implicated. Although a cocktail of three or four major classes of antihypertensive drugs are recommended for treatment, the benefits of pharmacological interventions is limited in many patients, so surgical denervation of the renal artery is widely practiced to improving patient outcome. Thus, surgical interventions include (i) renal sympathetic denervation, (ii) renal sympathetic innervation, and (iii) device-based carotid baroreceptor electric stimulation may be considered back-to-life options to treat resistant hypertension. Moreover, over the years, these surgical procedures have been refined and fine-tuned to optimize benefits, while minimizing adverse effects. Thus, the current surgical practice has been greatly improved from the time of inception. Therefore, this review will focus on the role of surgical interventions in the treatment and management of resistant hypertension. With the global escalation of hypertension in epidemic proportions and the huge socio-economic burden posed to patients, their families and healthcare systems, it is of utmost importance to improve treatment strategies for all forms of hypertension including resistant hypertension.

Update on Renal Sympathetic Denervation for the Treatment of Hypertension.

Hypertension is a leading risk factor for all-cause mortality in adults; however, medication non-adherence and intolerance present an enormous treatment challenge. Given the critical role of renal sympathetic nerves in neurogenic control of blood pressure and pathophysiology of hypertension, renal sympathetic denervation (RDN) has been explored as a therapeutic strategy in hypertension treatment over the last 15years. In this review, we will discuss the role of renal sympathetic nerves in the pathophysiology of hypertension, provide an update on the available evidence regarding the short- and long-term safety and effectiveness of RDN in the treatment of hypertension, and consider its future perspectives. RDN is a percutaneous endovascular catheter-based neuromodulation approach that enables ablation of renal sympathetic nerve fibers within the adventitial layer of the renal arteries using radiofrequency (most extensively studied), ultrasound energy, or neurolytics (e.g., alcohol). In the last decade, advancements in procedural techniques and well-designed sham-controlled trials utilizing 24-h ambulatory blood pressure measurements have demonstrated that RDN has an excellent safety profile and results in a modest reduction of blood pressure, in a wide range of hypertensive phenotypes (mild to resistant), irrespective of antihypertensive drug use and this effect is sustained over a 3-year period. Superiority of a particular RDN modality has not been yet established. Despite strong evidence demonstrating efficacy and safety of RDN, current data does not support its use as a primary approach in the treatment of hypertension due to its modest treatment effect and concerns around long-term sustainability. Perhaps the best utility of RDN is in hypertensives intolerant to antihypertensive medications or as an adjunct to aldosterone antagonists in the management of resistant hypertension. Patient selection will be critical to demonstrate a meaningful benefit of RDN. Future well-designed studies are necessary to determine predictors and measures of response to RDN, long-term efficacy given question of renal nerve regeneration, comparison of available technologies, safety in patients with advanced kidney disease, and improvement in patient quality of life measures.

IMPACT OF SHAM PROCEDURE ON BLOOD PRESSURE LEVELS IN PATIENTS WITH UNCONTROLLED HYPERTENSION: A SYSTEMATIC REVIEW AND META-ANALYSIS OF RENAL DENERVATION TRIALS

Objective: Renal denervation (RDN) has been studied extensively during the last decade. Its role in the management of resistant hypertension has been placed at the epicenter after the conduction of the second-generation trials. The impact of sham procedure however remains undetermined. Design and method: PubMed and CENTRAL, along with grey literature sources, were searched from their inception to May 2019 for randomized, sham-controlled trials primarily evaluating the efficacy and safety of RDN on the management of hypertension, irrespective of study blinding, setting and sample size. We extracted those data concerning the effect of sham procedure on ambulatory and office blood pressure levels (ABP and OBP, respectively). Results: Six randomized, sham-controlled trials were identified and included in the meta-analysis. In total, 981 patients with hypertension were randomized in all 6 trials to undergo either RDN (n = 585) or sham-procedure (n = 396). It was documented that the sham procedure did not affect significantly 24-h systolic ABP levels (MD: -1.15, 95% CI: -2.67 to 0.36, I^2 = 0%); however, it induced a significant decrease in 24-h diastolic ABP levels by 1.52 mm Hg (95% CI: -2.53 to -0.51, I^2 = 0%). In addition, it was demonstrated that the sham procedure resulted in a significant decrease in systolic OBP by 3.05 mm Hg (95% CI: -5.30 to -0.81, I^2 = 0%) and a non-significant decrease in diastolic OBP by 0.65 mm Hg (95% CI: -2.03 to 0.73, I^2 = 0%). No major safety issues arose. Conclusions: Sham procedure is a safe procedure, providing significant or marginally non-significant decrease in both ABP and OBP levels.
