Obesity-related glomerulopathy (ORG) is morphologically characterized by glomerulomegaly with or without observable focal segmental glomerulosclerosis under light microscope, with decreased podocyte density and number, and with increased foot‑process width observed under electron microscope. The severity of podocyte injury is correlated with the degree of proteinuria and renal dysfunction. However, the pathogenesis of ORG is not well understood. The aim of the present study was to explore the possible pathogenic role of aldosterone (ALDO) in ORG...

BACKGROUND: Laparoscopic adrenalectomy is considered the gold standard technique for the treatment of benign small and medium size adrenal masses (<6 cm), due to low morbidity rate, short hospitalization and patient rapid recovery. The aim of our study is to analyse the feasibility and efficiency of this surgical approach in a broad spectrum of adrenal gland pathologies. METHODS: Pre-operative, intra-operative and post-operative data from 126 patients undergone laparoscopic adrenalectomy between January 2003 and December 2015 were retrospectively collected and reviewed...

Renal denervation and spironolactone have both been proposed for the treatment of resistant hypertension, but their effects on preclinical target organ damage have not been compared. Twenty-four patients with 24-hour systolic blood pressure ≥140 mm Hg despite receiving three or more full-dose antihypertensive drugs, one a diuretic, were randomized to receive spironolactone or renal denervation. Changes in 24-hour blood pressure, urine albumin excretion, arterial stiffness, carotid intima-media thickness, and left ventricular mass index were evaluated at 6 months...

BACKGROUND: Spironolactone, a nonselective mineralocorticoid receptor antagonist (MRA), may have a deleterious effect on glycemia. The objective of this review was to assess current knowledge on MRAs' influence (spironolactone, eplerenone, and canrenone) on glucose homeostasis and the risk of diabetes. METHOD: A systematic review was conducted using the Medline database on articles published from 1946 to January 2017 that studied the effects of MRAs on any glucose-related endpoints, without any restrictions regarding the participants' characteristics...

Eleven cases of dilated cardiomyopathy have been diagnosed and treated in captive Livingstone fruit bats ( Pteropus livingstonii) in the United Kingdom over the past 7 yr. All but one case received treatment with a diuretic plus an angiotensin-converting enzyme inhibitor (ACEI), and, or pimobendan. One case is still under treatment with pimobendan alone, following diagnosis before onset of clinical signs. Diuretic treatment consisted of furosemide at a dose rate of 0.5-5 mg/kg, one to three times daily, and, or spironolactone at a dose rate of 1-4 mg/kg, once or twice daily...

REVIEW
Alberto Morganti, Giuseppe Mancia
Resistant hypertension (RH) can be diagnosed if blood pressure (BP) is not controlled with the combination of three antihypertensive drugs, including a diuretic, all at effective doses. Patients affected by this condition exhibit a marked increase in the risk of cardiovascular and renal morbid and fatal events. They also exhibit an increased activity of the sympathetic nervous system which is likely to importantly contribute at the renal and other vascular levels to the hypertensive state. Almost 10years ago renal denervation (RDN) by radiofrequency thermal energy delivery to the walls of the renal arteries was proposed for the treatment of RH...

INTRODUCTION: The pathophysiology of heart failure involves activation of several neurohormonal systems including the renin-angiotensin-aldosterone system. The mineralocorticoid receptor antagonist spironolactone has been shown to be beneficial in humans and dogs with heart failure. The objective of this pilot study was to investigate the efficacy and safety of spironolactone in cats with heart failure secondary to cardiomyopathy already treated with furosemide and an angiotensin-converting enzyme inhibitor...

A middle-aged woman with obesity, hyperlipidaemia and diet-controlled diabetes was referred for resistant hypertension. Her blood pressure (BP) was uncontrolled on five medications, including a diuretic. Physical exam revealed a systolic ejection murmur, and ECHO demonstrated moderate hypertrophy. Laboratory examination revealed elevated aldosterone level (20.7 ng/dL) and elevated aldosterone:renin ratio (41.4 (ng/dL)/(ng/mL/h)), meeting criteria for primary aldosteronism (PA), and confirmed by saline infusion testing...

Mineralocorticoid receptor antagonists (MRAs), such as spironolactone, eplerenone and finerenone, have an established role in the treatment of heart failure. However, many experimental and clinical studies have shown that aldosterone also plays a pivotal role in a variety of other pathophysiological conditions within the cardiovascular system. Aldosterone has been suggested to promote inflammation, endothelial dysfunction and smooth muscle cell hyperplasia during the development of atherosclerosis, thereby promoting the development of coronary artery disease (CAD)...

OBJECTIVES: This study sought to investigate the association of left ventricular (LV) untwisting rate (UT) and E/e' ratio with the response of exercise capacity to spironolactone in heart failure with preserved ejection fraction (HFpEF). BACKGROUND: In most patients with HFpEF, LV filling abnormalities represent a central component in the development of dyspnea. LV diastolic filling is determined by the interplay of passive (LV stiffness and myocardial collagen content, reflected by E/e' ratio) and active myocardial properties (UT, a precursor to isovolumic pressure decay and contributor to diastolic suction)...

In this study a new high sensitive method of spironolactone (SP) determination is proposed using voltammetric technique. As the working electrode amalgam film silver based electrode (Hg(Ag)FE) was applied, that resulted in obtaining low limit of spironolactone detection, ex. for the preconcentration time 45 s obtained detection limit was 4.7·10-9 mol L-1 (1.96·10-6 g L-1). The linear response of spironolactone signal on mercury film electrode was obtained in the range of concentration from 15·10-9 to 3.0·10-6 mol L-1 and the obtained repeatability measured as RSD was very good, with the value of 2...

Rationale: Resistant hypertension is a major health concern with unknown etiology. Spironolactone is an effective anti-hypertensive drug, especially for patients with resistant hypertension, and is considered by the World Health Organization (WHO) as an "essential" medication. Although spironolactone can act at the mineralocorticoid receptor (NR3C2), there is increasing evidence of mineralocorticoid receptor (MR)-independent effects of spironolactone. Objective: Here, we detail the unexpected discovery that pannexin 1 (Panx1) channels could be a relevant in vivo target of spironolactone...

Background: Recent evidence suggests that the mineralocorticoid receptor antagonist spironolactone should be the preferred fourth line antihypertensive treatment in resistant hypertension (RHTN). Whether spironolactone improves blood pressure (BP) control in heart failure with preserved ejection fraction (HFpEF) and RHTN is unknown. Methods: We identified patients with RHTN, defined as baseline systolic blood pressure (SBP) between 140 and 160 mmHg on 3 or more medications, in the Americas cohort of the TOPCAT trial, in which patients with HFpEF were randomized to spironolactone vs...

REVIEW
Milton Packer
Diabetes is characterized by an increased activity of the sodium-hydrogen exchanger (NHE) in the glomerulus and renal tubules, which contributes importantly to the development of nephropathy. Despite the established role played by the exchanger in experimental studies, it has not been specifically targeted by those seeking to develop novel pharmacological treatments for diabetes. This review demonstrates that many existing drugs that are commonly prescribed to patients with diabetes act on the NHE1 and NHE3 isoforms in the kidney...

Furosemide and spironolactone are commonly prescribed antihypertensive drugs. Canrenone is the main degradation product and main metabolite of spironolactone. Ratio subtraction and extended ratio subtraction spectrophotometric methods were previously applied for quantitation of only binary mixtures. An extension of the above mentioned methods; successive ratio subtraction, is introduced in the presented work for quantitative determination of ternary mixtures exemplified by furosemide, spironolactone and canrenone...
