BACKGROUND: Heart failure (HF) is a disease of neurohumoral dysfunction and current pharmacological therapies for HF have not improved mortality rates, thus requiring additional new strategies. Waon therapy for HF patients may be a complementary strategy with peripheral vasodilation via nitric oxide. We hypothesized that Waon therapy would improve neurohumoral factors, such as natriuretic peptides (NP) and the renin-angiotensin-aldosterone system (RAAS) in HF.Methods and Results:Plasma samples were collected from patients enrolled in the WAON-CHF Study (Waon therapy (n=77) or control (n=73)) before and after the treatment...

Leslie Williams, Cheyn Onarecker
CLINICAL QUESTION: In congestive heart failure patients with preserved ejection fraction, does spironolactone improve cardiac outcomes? ANSWER: No. A randomized controlled trial of patients with heart failure and an ejection fraction > 45% showed that spironolactone did not significantly reduce the incidence of the primary composite outcome of death from cardiovascular causes, aborted cardiac arrest, or hospitalization for the management of heart failure. LEVEL OF EVIDENCE FOR THE ANSWER: A...

OBJECTIVES: There is a growing evidence of increased risk of cerebrovascular events in primary aldosteronism (PA). Nevertheless, acute neurologic ailment as presenting feature of PA is uncommon. Our aim is to highlight the diagnosis challenges in stroke unmasking PA and to discuss the underlying physiopathology and management dilemmas. MATERIALS AND METHODS: We hereby describe three consecutive rare cases of stroke revealing PA. All patients had brain imaging and thorough biological and morphological assessment to rule out other etiologies of stroke...

Add-on mineralocorticoid-receptor-antagonists (MRAs) spironolactone and eplerenone can enhance the cardioprotective action of angiotensin-converting-enzyme-inhibitors (ACEIs), angiotensin-receptor-blockers (ARBs) and/or β-blockers in non-dialysis patients with congestive heart failure (CHF) and reduced left ventricular (LV) ejection fraction. The efficacy and safety of MRAs among patients on chronic dialysis is less well studied. A growing body of evidence derived from small randomized studies suggests that MRA therapy may improve a number of surrogate cardiovascular (CV) risk factors (i...

One objective in developing adverse outcome pathways (AOPs) is to connect biological changes that are relevant to risk assessors (i.e., fecundity) to molecular and cellular-level alterations that might be detectable at earlier stages of a chemical exposure. Here, we examined biochemical responses of fathead minnows (Pimephales promelas) to inform an AOP relevant to spironolactone's activation of the androgen receptor, as well as explore other biological impacts possibly unrelated to this receptor. Liquid chromatography with high resolution mass spectrometry (LC-MS) was used to measure changes in endogenous polar metabolites in livers of male and female fish that were exposed to five water concentrations of spironolactone (0, 0...

OBJECTIVE: Aldosterone excess has been equally associated with resistant hypertension (RHT) and obstructive sleep apnoea (OSA). We conducted a randomized controlled study to assess the effect of continuous positive airway pressure (CPAP) treatment on 24-h urinary aldosterone excretion in patients with RHT and moderate/severe OSA. METHODS: A total of 117 patients were randomized (57 CPAP and 60 control groups). Aldosterone excretion was determined by 24 h urine (24h-UAldo) collected at randomization and after 6 months of follow-up...

BACKGROUND: The clinical manifestations of acute heart failure (AHF) and respiratory infection (RI) frequently overlap in patients presenting with dyspnoea at the emergency department (ED). The neutrophil to lymphocyte (N/L) and platelet to lymphocyte (P/L) ratios have been proposed as diagnostic and prognostic indices in this setting. OBJECTIVE: To evaluate the ability of N/L and P/L ratios to discriminate the cause of dyspnoea in patients admitted with an initial diagnosis of AHF-RI...

Steroid hormones like aldosterone have been conclusively shown to elicit both late genomic and rapid, nongenomically initiated responses. Aldosterone was among the first for which rapid, clinically relevant effects were even shown in humans. Yet, after over 30 years of research, the nature of receptors involved in rapid actions of aldosterone is still unclear. Such effects may be assigned to the classical, intracellular steroid receptors, in this case mineralocorticoid receptors (MR, class IIa action Mannheim classification)...

A 70-year-old man who was diagnosed with unresectable advanced rectal cancer with multiple liver metastases, received oxaliplatin-based treatment with bevacizumab as first-line chemotherapy and irinotecan-based treatment with bevacizumab as second-line chemotherapy for a total of 17 months. The patient was treated with regorafenib (160 mg/day for 3 weeks) as third-line chemotherapy. Following completion of one course of regorafenib treatment, the patient complained of abdominal distension. Computed tomography (CT) examination identified liver atrophy and massive ascites, while no such symptoms were observed prior to the regorafenib treatment...

The present study reported a case of portopulmonary hypertension (POPH) that was secondary to underlying liver cirrhosis in a 58-year-old woman, who was successfully treated with low-dose tolvaptan. The patient had suffered from refractory peripheral edema and electrolyte abnormalities, including severe hypokalemia, under the combination therapy of sildenafil, ambrisentan, furosemide and spironolactone. Subsequent to the initiation of low-dose tolvaptan at 3.75 mg/day with concurrent de-escalation of the dose of furosemide, the daily urine volume increased, peripheral edema improved and the serum potassium level increased immediately...

Bisphosphonate, tetracycline and spironolactone use has been shown to increase gastro-oesophageal inflammation, an accepted risk factor for cancer. However, evidence on the effect of these medications on gastro-oesophageal cancer risk are mixed or missing entirely. Therefore, we conducted a nested case-control study using the Primary Care Clinical Information Unit Research (PCCIUR) database from Scotland. Cases with oesophageal or gastric cancer between 1999 and 2011 were matched to up to five controls based on age, gender, year of diagnosis and general practice...

Acne is one of the most prevalent skin conditions seen by dermatologists. The cosmetic sequelae of severe acne, including scarring and pigmentation, have a profound psychological impact on those in icted. Topical (eg, retinoids, antibiotics, dapsone, hydroxyacids) and oral treatments (eg, antibiotics and/or spironolactone) are often bene cial to control acne or in the instance of oral isotretinoin use, rid the acne permanently; however, these treatments have very little affect on the ultimate cosmetic outcome of the acne scarring and skin texture that results...

Two Caucasian girls, both of normal weight and body mass indices, were diagnosed with type A insulin resistance (IR) in childhood. Case 1 presented with premature adrenarche aged 7 years, then by age 12 years had hirsutism, acne, acanthosis nigricans, and asymptomatic diabetes. Subsequent investigation revealed raised adiponectin (15.3 mg/L) and heterozygous p.Pro1205Leu mutation in the INSR gene encoding the insulin receptor. She experienced postprandial hypoglycaemia on metformin; acarbose was trialled and discontinued aged 16 years, as she became normoglycaemic...

PURPOSE OF REVIEW: The purpose of the review is to examine whether measurement of aortic stiffness could be especially value-adding for risk stratification and treatment among patients with resistant hypertension (RH). RECENT FINDINGS: Adverse arterial remodeling and increased aortic stiffness is associated with RH, and it may be of additional clinical benefit to measure aortic stiffness in these patients. However, there is insufficient evidence to determine whether aortic stiffness is excessively high relative to the level of blood pressure (BP) among people with RH...

BACKGROUND: Ascites remains the most common cause of hospitalization among patients with decompensated cirrhosis. Paracentesis is a relatively safe procedure with low complication rates. Computerized tomography (CT)-guided therapeutic paracentesis could be a safe and effective alternative to unaided or aided (ultrasonogram-guided) bedside paracentesis. In this retrospective study, we aimed to compare the efficacy, safety, and cost-effectiveness of CT-guided paracentesis with bedside paracentesis...
