Cost-Effectiveness Analysis of Patiromer and Spironolactone Therapy in Heart Failure Patients with Hyperkalemia.

Certain patients with heart failure (HF) are unable to tolerate spironolactone therapy due to hyperkalemia. Patiromer is a novel agent used to treat hyperkalemia and has been shown to be efficacious, safe, and well-tolerated. The potential clinical outcomes and economic value of using patiromer and spironolactone in patients with HF unable to otherwise tolerate spironolactone due to hyperkalemia are unclear. The objective of this analysis was to model the potential pharmacoeconomic value of using patiromer ...

Is there a potential association between spironolactone and the risk of new-onset diabetes in a cohort of older patients with heart failure?

Some evidence suggests that spironolactone may have a deleterious effect on glucose homeostasis. The objective of this study was to assess whether spironolactone use is associated with a higher risk of developing diabetes in a large cohort of patients with heart failure (HF).

Spironolactone inhibits endothelial-mesenchymal transition via the adenosine A2A receptor to reduce cardiorenal fibrosis in rats.

The mechanisms underlying cardiorenal syndromes are complex and not fully understood; Fibrosis seems to be a primary driver of the diseases' pathophysiology. Spironolactone can reduce cardiac or renal fibrosis by inhibiting endothelial-mesenchymal transition (EndMT). Spironolactone protection may rely on activation of adenosine receptors, but the role of the adenosine A2A receptor (A2AR) is unclear. We hypothesize that spironolactone may modulate A2AR to suppress EndMT and reduce cardiorenal remodeling.

Eplerenone Versus Spironolactone in Resistant Hypertension: an Efficacy and/or Cost or Just a Men's Issue?

To review comparative efficacy and tolerability data between the two main mineralocorticoid receptor antagonists (MRAs), spironolactone and eplerenone, in patients with resistant hypertension (HTN). The focus was whether spironolactone, being the classical non-selective agent that has been used for years, albeit with several anti-androgenic side effects, can be rivaled by eplerenone, an apparently weaker, but better tolerated, more selective MRA.

The mineralocorticoid receptor antagonist spironolactone reduces alcohol self-administration in female and male rats.

Cortisol/corticosterone and the hypothalamic-pituitary-adrenal (HPA) axis serve an important role in modulating alcohol drinking behaviors. To date most alcohol research has focused on the functional involvement of corticosterone and the glucocorticoid receptor (GR), the primary receptor for corticosterone. Recent studies have indicated that the related mineralocorticoid receptor (MR), which binds both corticosterone and aldosterone, may also play a role in alcohol drinking. Therefore, the purpose of the pr...

Patiromer to Enable Spironolactone Use in the Treatment of Patients with Resistant Hypertension and Chronic Kidney Disease: Rationale and Design of the AMBER Study.

While chronic kidney disease (CKD) is common in resistant hypertension (RHTN), prior studies -evaluating mineralocorticoid receptor antagonists excluded patients with reduced kidney function due to risk of hyperkalemia. AMBER ( identifier NCT03071263) will evaluate if the potassium-binding polymer patiromer used concomitantly with spironolactone in patients with RHTN and CKD prevents hyperkalemia and allows more persistent spironolactone use for hypertension management.

Vascular compliance in women with polycystic ovary syndrome treated with spironolactone.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age in the United States and has been associated with several diseases including cardiovascular disease, obesity, and glucose intolerance. In this study, systolic blood pressure, diastolic blood pressure, pulse pressure (vascular compliance), large artery elasticity, systemic vascular resistance (SVR), total vascular impedance (TVI), and body mass index (BMI) were measured before and after treatment with spironol...

A simple UHPLC-PDA method with a fast dilute-and-shot sample preparation for the quantification of canrenone and its prodrug spironolactone in human urine samples.

Nowadays, the treatment of hypertension represents an important issue, particularly in developed countries. While in most cases the standard therapeutic approaches, consisting in the administration of 1 to 3 drugs, are adequate to reach adequate blood pressure levels, in some cases more drugs are needed: this condition is called "resistant hypertension". In this context, the administration of a diuretic, such as spironolactone or canrenoate salts, represents a standard practice. Since a reliable discriminat...

Potential spironolactone effects on collagen metabolism biomarkers in patients with uncontrolled blood pressure.

An increase in myocardial collagen content may contribute to the development of heart failure; this might be inhibited or reversed by mineralocorticoid receptor antagonists (MRAs). We investigated changes in serum concentrations of the collagen synthesis biomarkers N-terminal propeptide of procollagen type III (PIIINP) (primary outcome) and C-terminal propeptide of procollagen type I (PICP) (secondary outcome) after non-randomised initiation of spironolactone as add-on therapy among patients with resistant ...

The Impact of Spironolactone in Heart Failure With Preserved Ejection Fraction: What Phase of Diastole Is Helped?

Lack of evidence for feminization of males exposed to spironolactone in utero: a systematic review.

Mineralocorticoid receptor antagonism limits experimental choroidal neovascularization and structural changes associated with neovascular age-related macular degeneration.

Choroidal neovascularization (CNV) is a major cause of visual impairment in patients suffering from wet age-related macular degeneration (AMD), particularly when refractory to intraocular anti-VEGF injections. Here we report that treatment with the oral mineralocorticoid receptor (MR) antagonist spironolactone reduces signs of CNV in patients refractory to anti-VEGF treatment. In animal models of wet AMD, pharmacological inhibition of the MR pathway or endothelial-specific deletion of MR inhibits CNV throug...

Nanoamorphous Drug Products - Design and Development.

Most of the recent drug compounds coming out of the drug discovery pipeline are labile (multiple polymorphs), and need to be developed into robust marketed oral drug formulations. There are only 22 oral macroamorphous drug products approved by FDA and till date none approved oral nanoamorphous drug products. However, there are several oral nanoamorphous drug formulations (including both labile and non-labile drugs) being researched and a few of these are in the clinical trials. Due to the labile nature of t...

Effect of a novel nonsteroidal selective mineralocorticoid receptor antagonist, esaxerenone (CS-3150), on blood pressure and renal injury in high salt-treated type 2 diabetic mice.

Although beneficial antihypertensive and antialbuminuric effects of steroidal mineralocorticoid receptor (MR) antagonists have been shown, the use of these drugs has been clinically limited in diabetic kidney disease (DKD) because of the high incidence of side effects. Here, we aimed to examine the effect of a novel nonsteroidal selective mineralocorticoid receptor antagonist, esaxerenone, on blood pressure and renal injury in high salt-treated type 2 diabetic KK-A mice, a model of human hypertensive DKD. K...

The effects of glucocorticoids on depressive and anxiety-like behaviors, mineralocorticoid receptor-dependent cell proliferation regulates anxiety-like behaviors.

Glucocorticoids are vital stress response hormones and facilitate stress coping. However, sustained glucocorticoid exposure is associated with negative effects on brain. The precise role of glucocorticoids in depression and anxiety remains unclear. In the present study, we found that rats exposed to chronic unpredictable stress (CUS) showed anxiety-like behavior but not depressive-like behavior in the absence of glucocorticoid production. It was interesting to find that the level of serotonin (5-HT) and the...

Spironolactone depletes the XPB protein and inhibits DNA damage responses in UVB-irradiated human skin.

UVB wavelengths of light induce the formation of photoproducts in genomic DNA that are potentially mutagenic and detrimental to epidermal cell function. Interestingly, the mineralocorticoid and androgen receptor antagonist spironolactone (SP) was recently identified as an inhibitor of UV photoproduct removal in human cancer cells in vitro via its ability to promote the rapid proteolytic degradation of the DNA repair protein XPB (xeroderma pigmentosum group B). Using normal human keratinocytes in vitro and s...

An alternative strategy for combination therapy: Interactions between polymyxin B and non-antibiotics.

Antimicrobial resistance is increasing and few new antibiotics are in the development pipeline. Alternative strategies to treat infectious diseases such as combination therapy are urgently needed. Polymyxin B is a neglected and disused antibiotic with moderate antibacterial activity, and in this study we aimed to find synergistic interactions between polymyxin B and a wide range of non-antibiotics to improve its efficacy. Thirty non-antibiotic compounds from various drug classes were screened for synergisti...

Spironolactone and Outcomes in Older Patients with Heart Failure and Reduced Ejection Fraction.

The efficacy of mineralocorticoid receptor antagonists or aldosterone antagonists in heart failure with reduced ejection fraction (HFrEF) is well known. Less is known about their effectiveness in real-world older patients with HFrEF.

Aldosterone stimulation mediates cardiac metabolism remodeling via Sirt1/AMPK signaling in canine model.

Aldosterone (Aldo), a pivotal hormone that is ubiquitously expressed in systemic tissues of mammals, is a crucial factor in the pathogenesis of cardiac disease. Accumulating evidence suggests that disturbances in cell energy metabolism are involved in increasing aldosterone levels. However, the precise mechanism underlying the impact of cardiac metabolic remodeling underlying aldosterone stimulation remains limited. In this work, we evaluated the underlying effect of aldosterone on regulating cardiac metabo...

Delayed spironolactone administration prevents the transition from acute kidney injury to chronic kidney disease through improving renal inflammation.

Acute kidney injury (AKI) is not as harmless as previously thought since it may lead to chronic kidney disease (CKD). Because most of the time ischemic AKI occurs unexpectedly, it is difficult to prevent its occurrence and there are no specific therapeutic approaches to prevent the AKI to CKD transition. We aimed to determine whether mineralocorticoid receptor blockade (MRB) in the first days after ischemia/reperfusion (IR) can prevent progression to CKD.

Towards a circulating marker of hepato-visceral fat excess: S100A4 in adolescent girls with polycystic ovary syndrome - Evidence from randomized clinical trials.

S100A4 is a marker of subcutaneous adipose tissue dysfunction. Polycystic ovary syndrome (PCOS) is often driven by hepato-visceral adiposity. PCOS phenotypes are normalized more by reduction of central fat with spironolactone/pioglitazone/metformin (SPIOMET) than by oral contraceptive (OC) treatment. We studied whether circulating S100A4 concentrations are high in adolescents with PCOS and, if so, whether they normalize more with OC or SPIOMET. Assessments included circulating S100A4, endocrine markers, bod...

Screening and evaluation of antiviral compounds against Equid alpha-herpesviruses using an impedance-based cellular assay.

Equid alpha-herpesviruses (EHV) are responsible for different diseases in equine population. EHV-1 causes respiratory diseases, abortions and nervous disorders, EHV-4 causes respiratory diseases and sporadic abortion, while EHV-3 is responsible of equine coital exanthema. In view of the lack of efficacy of vaccines against EHV-1 and EHV-4 and in the absence of vaccines against EHV-3, the use of antiviral treatment is of great interest. In this study, we documented the interest of the Real-Time Cell Analysis...
