Spirolactone hypertension

Luyun Fan, Wenjun Ma, Huimin Zhang, Jun Cai
RATIONALE: Iliac arterial fibromuscular dysplasia (FMD) was rarely reported and its demographic, clinical, and imaging features have not been precisely described resulting in uncertain therapeutic methods. PATIENT CONCERNS: A 31-year-old man was referred because of 3-month-ago onset hypertension, low serum potassium, and a small-sized right kidney with normal renal artery under ultrasound examination. This patient was suspected of primary aldosteronism, whereas spirolactone was poorly effective...

The cDNA of the mineralocorticoid receptor (MR) was cloned 30 years ago, in 1987. At that time, spirolactone, the first generation of synthetic steroid-based MR antagonists (MRAs), which was identified in preclinical in vivo models, had already been in clinical use for 30 years. Subsequent decades of research and development by Searle & Co., Ciba-Geigy, Roussel Uclaf and Schering AG toward identifying a second generation of much more specific steroidal MRAs were all based on the initial 17-spirolactone construct...

OBJECTIVE: To analyze the prognostic value of serum albumin for in-hospital mortality in patients with heart failure. METHODS: A total of 2 430 consecutive heart failure patients aged at (68±14) years were enrolled in the study. Patients were divided into 2 groups according to serum albumin concentration on admission: the normoalbuminemia group (≥35 g/L) and the hypoalbuminemia group (<35 g/L). Propensity score matching was conducted to reduce confounding bias between the groups...

After their introduction in 1959, thiazide diuretics have become the cornerstone in the managment of heart failure and hypertension. They prevent sodium reabsorption in the upper segment of the distal tubule, increase the diuresis and, by diminishing the intravascular volume, they reduce the preload. With vigorous diuresis, cardiac output may drop under the critical level, and hypovolaemia, hypotension, syncopes and dehydratation with severe water-mineral disturbance may occur. A similar disorder takes place after aggressive administration of loop diuretics which act by the same mechanism at the ascending limb of the loop of Henle...

The contraceptive pill has been a revolution of the last 40 years. In Italy, however, it is much less widely used than in other countries. Explanations for this phenomenon range from religious implications and customs to misinformation and word-of-mouth communication of negative experiences. The oral contraceptive pill is often used to correct menstrual disorders, leading to poor results and side-effects. Recent advances in oral contraception have led to a substantial reduction in doses and side-effects. Low-dose pills contain minimal doses of progesterones and estrogens and ensure good control of the menstrual cycle...

Dysfunction of D2-like receptors has been reported in essential hypertension. Disruption of D2R in mice (D2-/-) results in high blood pressure, and several D2R polymorphisms are associated with decreased D2R expression. Because D2R agonists have antioxidant activity, we hypothesized that increased blood pressure in D2-/- is related to increased oxidative stress. D2-/- mice had increased urinary excretion of 8-isoprostane, a parameter of oxidative stress; increased activity of reduced nicotinamide-adenine dinucleotide phosphate oxidase in renal cortex; increased expression of the reduced nicotinamide-adenine dinucleotide phosphate oxidase subunits Nox1, Nox2, and Nox4; and decreased expression of the antioxidant enzyme heme-oxygenase-2 in the kidneys, suggesting that regulation of reactive oxygen species (ROS) production by D2R involves both pro-oxidant and antioxidant systems...

OBJECTIVE: Disturbances of the synthesis and breakdown of the extracellular matrix of arterial walls have emerged as key features of the atherosclerotic process. We observed the changes of circulating procollagen marker for type III collagen turnover rate, the N-terminal propeptide P III NP and vascular resistance in hypertensive patients treated with various antihypertensive regimens. METHOD: A total of 130 light to moderate hypertensive patients were randomly assigned to receive enalapril (group B, n = 43), enalapril + spirolactone (20 mg/d, group A, n = 44) and anti-hypertensive drugs not directly affecting RAAS (calcium antagonist, beta-blocker, group C, n = 43) for 1 year...

Spirolactones harboring various C7 substituents are aldosterone antagonists, and some of them are used in the treatment of essential hypertension. They bind to the human mineralocorticoid receptor and render it transcriptionally inactive. Structural analysis using a three-dimensional homology model of the ligand-binding domain of the receptor has revealed that the Met852 residue of the ligand-binding cavity faces the C7 substituent of spirolactones. We therefore tested the binding capacities of C7-substituted spirolactones in an in vitro system expressing either the mutant receptor, in which Met852 was replaced by alanine, or the wild-type receptor...

Drospirenone (DRSP) is a novel progestogen derived from 170alpha-spirolactone. Its pharmacodynamic profile is closer to progesterone than any other currently available progestogen. DRSP has progestational, antialdosterone and antiandrogenic properties, but is devoid of any estrogenic, androgenic, glucocorticoid, antiglucocorticoid or mineralocorticoid activities. The affinity of DRSP for the mineralocorticoid receptor makes it an antagonist of aldosterone, which is not only important in the renin-angiotensin-aldosterone system (RAAS), but also acts directly on the cardiovascular system...

Recent studies suggest that a dysregulation of the aldosterone system is involved in the pathophysiology of different cardiovascular diseases, including myocardial failure and several cases of essential hypertension. In both rat models and in humans, aldosterone action has been shown to induce heart remodeling and interstitial and perivascular fibrosis of the myocardium. For these reasons, a rationale for the use of aldosterone antagonists (ARAs) of the spirolactone family, which have been available for decades in the treatment of aldosterone excess syndromes, has now emerged...

Many therapeutic options are proposed for the treatment of diastolic heart failure although no consensus has been established. In experimental trials, several drugs have demonstrated a potentially beneficial effect on ventricular diastolic dysfunction and could be used for diastolic heart failure: nitrate derivatives, converting enzyme inhibitors, angiotensin II antagonists, spirolactones and bradycardia agents. CLINICAL PRACTICE: In everyday clinical practice, low-dose diuretics and treatments aimed at reducing the triggering factor leading to episodes of heart failure are used alone or in combination with treatments aimed at the underlying cause of the diastolic dysfunction: betablockers, calcium inhibitors or nitrate derivatives for ischemic heart disease, drug therapy for hypertension, anti-diabetes agents, anti-arrhythmic agents for atrial fibrillation...

In autumn 1999 results of two well-controlled studies were published that are consistent with a frequent association between Helicobacter pylori seropositivity and coronary heart disease (CHD). Concerning the therapy of CHD, attention is mainly focused on new thrombolytic agents, bypass grafting (CABG) and balloon angioplasty (PTCA). In patients with intractable angina where aggressive medical therapy was exhausted and who were no longer candidates for CABG or PTCA, transmural laser revascularisation (TMLR), enhanced external counterpulsation (EECP) and spinal cord stimulation can be considered...

Isolated hypoaldosteronism is found in 75% diabetics where the disease has persisted for 10 or more years. Sporadically it is found in congenital autonomous neuropathy, in acute glomerulonephritis, in gouty kidney, tubulointerstitial nephritis, after transplantation of the kidney, on mytomycin etc. During dynamic testing of the response of plasma renin activity and aldosterone to the administration of furosemide and a vertical position in diabetics a significantly reduced response was recorded as compared with non-diabetic hypertonic subjects...

Diuretics, together with other drugs and general measures, are of prime importance in the medical treatment of most heart failure patients, namely those with acute pulmonary oedema and overt congestive heart failure. Their beneficial effects result not only from preload and afterload reduction, but also because diuretics are able to improve responses to nitrates and ACE-inhibitors. The appropriate utilisation of diuretics in heart failure therapy frequently involves the use of efficient small doses and drug associations, namely between loop diuretics, thiazides, potassium sparing agents and spirolactone...
