Aldosterone has attracted significant consideration for its role in the progression of renal injury. Since apoptotic cell loss contributes to the deterioration of renal function, we examined the effect of aldosterone on tubular cell apoptosis. To determine dose and time course effect, human renal proximal tubular (HK2) cells were treated with aldosterone at different doses and for variable time periods followed by evaluation for apoptosis. To determine the role of mineralocorticoid receptors (MR) and oxidative stress, HK2 cells were treated with either vehicle or aldosterone in the presence or absence of spironolactone/antioxidants/free radical scavengers (FRS) followed by evaluation for apoptosis. The presence of MR was evaluated using RT-PCR. Reactive oxygen species (ROS) generation was evaluated using redox-sensitive dyes. Effect of aldosterone was evaluated on dephosphorylation of phospho-Bad and accumulation of cytosolic cytochrome c. Human tubular cells express MR. Aldosterone promotes tubular cell apoptosis in a dose- and time-dependent manner. This effect of aldosterone is mediated through MR and associated with generation of ROS. Antioxidants and FRS partially attenuated the proapoaptotic effect of aldosterone. Aldosterone enhanced dephosphorylation of phospho-Bad and accumulation of cytosolic cytochrome c. We conclude that aldosterone-induced tubular cell apoptosis is mediated through the activation of the mitochondrial pathway and generation of ROS.

Mercury binding to bile components and the correlation between the amount of mercury bound in the bile fraction 2 and the rate of mercury biliary excretion were studied in female rats exposed to intravenously injected HgCl2 after pretreatment with a series of 14 chemical agents. After pretreatment with the tested agent, 203Hg was detectable both in the bile fraction 1 and 2. Distribution pattern of 203Hg between the two fractions appeared to be linked with the chemical structure of the formed mercury complex. Pretreatment with these agents did not inhibit the formation of the bile fraction 3. By their influence on the 203Hg distribution between the bile fractions 1 and 2, the tested agents can be roughly divided into 3 groups: the content of 203Hg in the bile fraction 2 is about 10--20% and does not change significantly within the first 24 hours after 203 HgCl2 injection (cysteine, penicillamine, disodium ethylenediaminotetraacetate -- Na2EDTA, sodium diethyldithiocarbamate, sodium alanindithiocarbamate, acrylonitrile); the the 203Hg content in the bile fraction 2 increases (thiophenolacetate); the content of 203Hg in fraction 2 is initially several times higher than that in the bile fraction 1, but then decreases during the first 24 hours (2,3-dimercaptopropanol -- BAL, sodium 2,3-dimercaptopropanesulphonate, spironolactone, Thiomestron). The rate of mercury biliary excretion (Rb) was found to be closely correlated with the relative amount of mercury present in the bile fraction 2 (a2), if a2 > 30%, both in vivo (Rb = 1.077 a2 + 0.758) and invitro (Rb = 1.067 a2 + 0.519) experiments. Practically identical values of the constant accompanying a2 in the two equations seem to indicate that one of the decisive factors influencing the rate of mercury biliary excretion in rats is rather the mercury affinity for the bile fraction 2 components than the agent-induced mercury transport mechanisms. For a2 < 30% the correlation is non-linear and the excretion is rather inhibited than enhanced.

The use of aldosterone blockers in the pharmacologic therapy for heart failure (HF) in patients with left ventricular systolic dysfunction has been shown to significantly reduce overall mortality, sudden cardiac death, and hospitalization. Patient adherence to polypharmaceutical regimens including aldosterone blockade and other key medication components is a concern for clinicians and their patients. A retrospective cohort study was conducted using integrated US pharmacy/medical claims covering 44.5 million lives. Inclusion criteria included the following: age at least 50 years, newly prescribed spironolactone or eplerenone from 2002 to 2006, with HF diagnosis within 12 months of prescription initiation and follow-up of at least 6 months to assess outcomes (12 months for adherence). Compliance was measured as the proportion of days covered (prescription days supply in the first year postindex for 365 days), and persistence was measured as days from the first to the last prescription. Of 388,523 patients with HF, 60,183 patients (15.5%) received an aldosterone blocker (n = 2024 for eplerenone, n = 58,159 for spironolactone), from which a newly treated subset was studied (n = 568 eplerenone, n = 11,982 spironolactone). Proportion of days covered was significantly greater for eplerenone (79% ± 42%) than for spironolactone (66% ± 42%, P < 0.01). Persistence was significantly higher for eplerenone than for spironolactone (P < 0.01) with discontinuation before 1 year at 49.5% and 73.7%, respectively. This analysis shows that a majority of patients did not receive an aldosterone blocker after HF diagnosis despite cardiovascular event risks and raises the hypothesis that eplerenone is associated with higher compliance and persistence as compared with spironolactone.

The binding sites for aldosterone and a potent aldosterone antagonist (SC-26304) were studied in kidney cytosol from adrenalectomized rats. Preformed cytosol and kidney slices were incubated with 3H-labeled steroids in a wide range of concentrations. The recovery and characteristics of the binding sites were affected by the incubation and homogenization conditions. High-affinity, Type I mineralocorticoid binding was reduced by more than 95% when cytosol was incubated at 25 degrees C in the presence of calcium. Tissue dilution also affected the binding sites. SC-26304 was bound to high- and low-affinity receptors, similar to the binding of aldosterone. The physiologic response to aldosterone could result from binding to either or both sets of sites. Some of the physiologic responses to spirolactones could represent antagonism of the binding of aldosterone to either or both sites. A convenient method is presented for describing the relative occupancy of several different sites by any particular steroid.

TODAY: The management of heart failure (HF) has considerably progressed over the last two decades. Treatment today relies on prevention and treatment of congestion (limited salt intake, diuretics, converting enzyme inhibitors) and limiting neurohormone stimulation (converting enzyme inhibitors +/- aldactone, beta-blockers). IN THE YEARS TO COME: Based on new concepts, several therapeutic strategies are interesting: blocking over vasoconstrictor systems which have not been taking into account; stimulation of vasodilator and natriuretic systems; modulation of cardiac remodelling; modulation of the immune and inflammatory systems; modification in intrinsic contractility; prevention of rhythm disorders. Among these differing strategies and molecules, it is not easy to predict those that will change the HF prognosis. In any event, their efficacy and safety remain to be demonstrated with large cohort randomised studies. THE PRINCIPLES: To reduce the number of drugs administered, two options appear particularly interesting: measurement of hormone levels (BNP) in order to adjust treatment and administration of molecules with greatest efficacy and safety profiles; limit cardiac remodelling by using new imaging techniques to detect it more precisely and select the molecule(s) exerting the required effect. To target the new molecules better, patients should be classified according to their etiology, stage and progressive profile of their disease, cardiac remodelling, expression of principle endocrine systems and pro-inflammatory cytokines, expression of inflammatory and immune systems and inherent genetic characteristics and response to treatment. This would permit the adaptation of treatment to each individual patient with heart failure.

1. Atrial natriuretic peptide (ANP)-null mice (Nppa(-/-)) exhibit cardiac hypertrophy at baseline and adverse cardiac remodelling in response to transverse aortic constriction (TAC)-induced pressure overload stress. Previous studies have suggested that natriuretic peptides could potentially oppose mineralocorticoid signalling at several levels, including suppression of adrenal aldosterone production, inhibition of mineralocorticoid receptor (MR) activation or suppression of MR-mediated production of pro-inflammatory factors. Thus, we hypothesized that the MR blocker eplerenone would prevent the exaggerated left ventricular (LV) remodelling/fibrosis and dysfunction after TAC in Nppa(-/-). 2. In the present study, Nppa(-/-) and wild-type Nppa(+/+) mice fed eplerenone- or vehicle (oatmeal)-supplemented chow since weaning were subjected to TAC or sham operation. The daily dose of eplerenone administered was approximately 200 mg/kg. At 1 week after TAC, LV size and function were evaluated by echocardiogram and LV cross-sections were stained with picrosirius red for collagen volume measurement. Total RNA was extracted from the LV for real-time polymerase chain reaction analysis of osteopontin. 3. Eplerenone had no effect on baseline hypertrophy observed in sham-operated Nppa(-/-) compared with Nppa(+/+) mice. Eplerenone attenuated the TAC-induced increase in LV weight in both genotypes and completely prevented LV dilation, systolic dysfunction and interstitial collagen deposition seen in Nppa(-/-) mice after TAC. However, serum aldosterone levels were lower in Nppa(-/-) compared with Nppa(+/+) wild types. No interaction between eplerenone and genotype in osteopontin mRNA levels was observed. 4. Eplerenone prevents adverse cardiac remodelling related to pressure overload in ANP-deficient mice, mainly due to an antifibrotic effect. The mechanism whereby ANP deficiency leads to excess hypertrophy, fibrosis and early failure following TAC is increased profibrotic signals resulting from excess or unopposed MR activation, rather than increased levels of aldosterone.

In acute studies, saline-drinking SHRSP (n = 5) were instrumented with radiotelemetry blood pressure (BP) probes and housed in metabolic cages. Mean arterial pressure and electrolyte excretion were quantified over the 24-h period after oral administration of vehicle or amiloride at 1, 3, 10, and 30 mg/kg. In a survival study, 8.5-week-old SHRSP were either untreated (control, n = 7) or given amiloride (1 mg/kg/day, n = 8) in their 1% NaCl drinking solution. Systolic BP, proteinuria, body weight, and renal and brain histopathology were assessed.

Resistant hypertension is inadequately controlled blood pressure (BP) despite treatment with at least three BP-lowering drugs. A popular hypothesis is that resistant hypertension is due to excessive Na(+)-retention, and that 'further diuretic therapy' will be superior to alternative add-on drugs.

Plasminogen activator inhibitor-1 (PAI-1) is an anti-thrombolytic factor that also promotes tissue fibrosis. Under certain conditions, exposure to aldosterone can result in cardiac fibrosis by an unknown mechanism. In the current study, we tested the hypothesis that PAI-1 is a mediator of aldosterone's fibrotic effects. Aldosterone increased levels of PAI-1 mRNA and protein in the H9c2 rat cardiac cell line, responses that could be blocked by the mineralocorticoid receptor (MR) antagonist spironolactone. Confocal microscopy confirmed an effect of aldosterone to increase PAI-1 expression with reversal by spironolactone. Aldosterone also increased PAI-1 expression in neonatal rat cardiomyocytes, which was again blocked by spironolactone. In the neonatal cardiomyocytes (but not the H9c2 cells), anti-transforming growth factor-beta1 antibody inhibited the PAI-1 response to aldosterone. In summary, aldosterone directly increased PAI-1 expression in two different cardiac muscle cell types, an effect that was dependent on MR. In the neonatal cells, there appeared to be a requirement for transforming growth factor-beta1.

Nine organic solvents and 47 commonly used P450 substrates and inhibitors were examined for their effects on coumarin 7-hydroxylase (CYP2A6) activity in human liver microsomes. Of the nine organic solvents examined (final concentration 1%, v/v), only methanol did not inhibit the 7-hydroxylation of coumarin (0.5 to 50 microM) by human liver microsomes. Dioxane and tetra-hydrofuran, which are structurally related to coumarin, were the most inhibitory solvents examined. Although the rates of coumarin 7-hydroxylation varied enormously among nine samples of human liver microsomes and cDNA-expressed CYP2A6 (Vmax = 179 to 2470 pmol/ mg protein/min), the Km for coumarin 7-hydroxylation was fairly constant (ranging from 0.50 to 0.70 microM). The following chemicals caused little or no inhibition of CYP2A6 as defined by a Ki > 200 microM: caffeine, chlorzoxazone, cimetidine, dextromethorphan, diazepam, diclofenac, erythromycin, ethinylestradiol, ethynyltestosterone, fluconazole, furafylline, furfural, hexobarbital, itraconazole, mephenytoin, methimazole, metronidazole, naringenin, naringin, nifedipine, norfloxacin, norgestrel, orphenadrine, quinidine, papaverine, phenacetin, pyrimethamine, ranitidine, spironolactone, sulfaphenazole, sulfinpyrazone, testosterone, tolbutamide, troleandomycin, and warfarin. In other words, these chemicals, at a final concentration of 100 microM, failed to inhibit CYP2A6 when the concentration of coumarin was equal to Km (0.50 microM). The following chemicals were classified as strong inhibitors of CYP2A6 (defined by Ki < 200 microM): clotrimazole, diethyldithiocarbamate, ellipticine, ketoconazole, 8-methoxypsoralen, 4-methylpyrazole, metyrapone, miconazole, alpha-naphthoflavone, nicotine, p-nitrophenol, and tranylcypromine. The potency with which each chemical inhibited the 7-hydroxylation of coumarin was independent of which sample of human liver microsomes was studied. One of the most potent inhibitors of coumarin 7-hydroxylase was 8-methoxypsoralen (methoxsalen), which was determined to be a mechanism-based inhibitor (suicide substrate) of CYP2A6 (k(inactivation) 0.5 min-1). With the exception of 8-methoxypsoralen, preincubation of human liver microsomes and NADPH with the aforementioned inhibitors did not increase their ability to inhibit CYP2A6. The most potent competitive inhibitor of CYP2A6 was tranylcypromine (Ki = 0.04 microM). Several of the chemicals that strongly inhibited CYP2A6, such as ketoconazole and tranylcypromine, are often used with the intention of selectively inhibiting human P450 enzymes other than CYP2A6. The results of this study underscore the need for a systematic evaluation of the specificity of commonly used P450 inhibitors.

Endothelial dysfunction is highly prevalent and associated with adverse outcomes among patients without obstructive coronary artery disease (CAD). Angiotensin II inhibition may improve endothelial function, but with continued treatment, "aldosterone escape" may occur. Thus, it is unknown if adding aldosterone blockade further improves endothelial function.

The effects of the addition of clonidine to diuretics on the mobilization of ascites in the short term (diuretic response and requirement of diuretics) and the long term (readmissions for tense ascites and requirement of diuretics) were examined in patients with cirrhosis and with increased sympathetic nervous system (SNS) activity. We also studied neurohormonal, hemodynamic effects and side effects of clonidine and diuretics. Patients were randomized to receive placebo (group 1, n = 32) or clonidine (0.075 mg) twice daily (group 2, n = 32) for 3 months. After 8 days and for 10 days duration, spironolactone (200 mg/day) was added in both groups. After this period, the dosages of diuretics were individually increased until diuretic response. Responding patients were discharged and followed at the outpatient clinic. During the first hospitalization, the time needed for diuretic response was shorter in group 2 than in group 1. The mean requirement for diuretics was significantly higher in group 1 than in group 2, and the diuretic complications (hyperkalemia and renal impairment) were significantly lower in group 2. Clonidine induced a permanent decrease in SNS activity and delayed decrease in renin/aldosterone levels. During the follow-up, the time to the first readmission for tense ascites was shorter in group 1 than in group 2. Readmissions related to tense ascites or diuretic complications were significantly lower in group 2. The mean requirement for diuretics was significantly higher in group 1 than in group 2. In conclusion, the additional administration of clonidine to diuretics induced an earlier diuretic response associated with fewer diuretic requirements and complications.

Our data confirmed that treatment-resistant depression is associated with hypercortisolism and these patients no longer show an hypothalamic-pituitary-adrenal response to the administration of a mineralocorticoid receptor antagonist, suggesting that there is a mineralocorticoid receptor malfunctioning, such as a down regulation, however, pharmacokinetics and pharmacodynamics in these subjects could also have had an effect on the lack of mineralocorticoid receptor response.

Plasma aldosterone levels and the serum electrolytes potassium, sodium and magnesium of 38 patients with healthy adrenals were determined. Under physiological conditions there were no significant correlations between these parameters. In two patients with an aldosterone producing adenoma of the adrenals (syndrome of Conn) we found very low levels of potassium and low levels of magnesium. The levels of sodium lay in the upper normal range. Plasma aldosterone levels are raised strongly. After resection of the tumors the mentioned parameters normalized. In 16 patients with cirrhosis and ascites we generally found values of aldosterone, potassium, sodium and magnesium which lay in the lowest normal range. Under treatment with spironolactone the aldosterone levels raised and reached values which are characteristical of the syndrome of Conn. Potassium raised to the upper normal range, magnesium raised significantly, sodium diminished slightly.

aldactone reviews

Previous studies have established a role for 5-hydroxytryptamine (5-HT)(2B) and 5-HT(1B) receptors in mediating enhanced contraction to serotonin (5-HT) in arteries from hypertensive deoxycorticosterone acetate (DOCA)-salt rats. To determine whether the observed increase in responsiveness was due to upregulation of 5-HT receptors, we used Western analysis to measure 5-HT(1B) and 5-HT(2B) receptor protein density. In endothelium-denuded aortas from hypertensive DOCA-salt rats (mean systolic blood pressure 192 +/- 6 mm Hg), 5-HT(1B) and 5-HT(2B) receptor proteins were upregulated approximately 2-fold compared with the response in the aortas of sham-operated control rats (mean systolic blood pressure 119 +/- 2 mm Hg). Contraction to 5-HT(2B) receptor agonists was also enhanced in arteries from Wistar-Furth rats given DOCA and salt. This strain is relatively resistant to the hypertensive effects of DOCA and salt treatment. A common factor between the model of DOCA-salt hypertension and the DOCA-salt--treated Wistar-Furth rats is the presence of mineralocorticoids. Therefore, we tested the hypothesis that mineralocorticoids can upregulate 5-HT(1B) and 5-HT(2B) receptors. Aortas from normal Sprague-Dawley rats were incubated with aldosterone (100 nmol/L) for 8, 12, 24, and 48 hours. The expression of 5-HT(2B) and 5-HT(1B) receptor proteins was significantly increased (approximately 2- fold over vehicle treatment) by 8 hours. 5-HT(2B) and 5-HT(1B) receptors were upregulated by aldosterone in a concentration-dependent manner, and incubation with spironolactone (10 micromol/L) blocked this upregulation. These data support the conclusion that the increased expression of 5-HT(1B) and 5-HT(2B) receptors observed in arteries from DOCA-salt rats may be partially due to mineralocorticoids acting via the mineralocorticoid receptor to modulate gene expression.

Renal sodium handling, neurohumoral systems, and systemic hemodynamics were investigated under baseline conditions in sitting posture in 10 healthy subjects, 11 patients with cirrhosis without, and 10 patients with cirrhosis with ascites. Furthermore, the effects of head-out water immersion, 1-week spironolactone administration, or their combination was assessed in the two groups of patients. Patients without ascites exhibited a significant increase in plasma norepinephrine concentration and a tendency toward an increase in plasma aldosterone concentration. Patients with ascites had a significantly lower mean arterial blood pressure despite significant reduction of urinary sodium excretion and fractional sodium excretion as well as an increase of plasma renin activity, plasma aldosterone, and norepinephrine concentration. In patients with ascites, the increase in renal sodium excretion and fractional sodium excretion following water immersion or spironolactone was clearly augmented by the combination of the two maneuvers. The same pattern was observed in patients without ascites. Our findings (a) underscore the importance of studying hemodynamics, renal function, and neurohumoral systems also in upright posture, (b) suggest a role of sympatico-adrenergic activation and proximal sodium retention in preascitic patients, and (c) are compatible with the vasodilation hypothesis of ascites formation.

The number of available studies on the role of human serum albumin (HSA) in the treatment of cirrhotic ascites is currently limited. In this study, we aimed to investigated the parameters associated with diuretic therapy with HSA in patients with advanced cirrhotic ascites. The patient inclusion criteria were cirrhotic ascites and a serum albumin (Alb) concentration of <3.5 g/dl. A total of 49 patients registered and 38 patients were ultimately included in this study. The enrolled patients were mainly treated with oral spironolactone and furosemide, which were not specified; the HSA amount was also not specified, although the administration period was set to a maximum of 7 days. Our results demonstrated that the administration of HSA significantly increased the serum levels of Alb [0.97 g/dl; two-sided 95% confidence interval (CI): 0.83-1.11 g/dl] and decreased body weight (-2.24 kg; 95% CI: -3.06 to -1.43 kg), hematocrit ratio (0.96; 95% CI: 0.94-0.98) and plasma renin concentration (day 4; geometric mean fold change, -0.1528; 95% CI: -0.2510 to -0.0545; log-transformed data) in patients with advanced cirrhotic ascites. The observed weight loss was found to be correlated with the total amount of HSA administered (P=0.0012), as indicated by the results of the multiple linear regression analysis. In conclusion, this study confirmed the efficacy of HSA in patients with advanced cirrhotic ascites.

Hyperkalemia was more frequent in patients who had been treated with blockers of the renin-angiotensin system than in patients who had used other hypotensors or who had not needed hypotensors and had not taken diuretics. Severe hyperkalemia (K > 7.5 mEq/L) was present both in patients treated with blockers of the renin-angiotensin system and in those treated with other hypotensors and in 1 case without hypotensor or diuretic treatment. 2 cases treated with blockers of the renin-angiotensin-aldosterone system with severe hyperpotassemia associated antialdosteronic diuretics, cumulating hyperpotassemic effects. Diuretic treatments with loop diuretics influenced the values of serum K of most patients. Hyperkalemia represents an important problem in nephrology because of the risks it induces in the treatment ofpre-dialysis CKD patients and it requires attentive monitoring.

Ovariectomy induced a significant decrease in beta-endorphin and allopregnanolone content in all brain areas analyzed and in circulating levels, whereas it increased allopregnanolone content in the adrenal gland. Estradiol valerate replacement increased beta-endorphin and allopregnanolone levels in all brain areas analyzed and in plasma/serum. Drospirenone treatment significantly increased beta-endorphin levels in all brain areas analyzed (with the only exception being the parietal lobe), whereas it produced no effect on allopregnanolone levels. The addition of drospirenone to estradiol valerate did not modify the effects of estradiol valerate on beta-endorphin or allopregnanolone levels. Drospirenone showed an additive and synergistic effect with estradiol in the neurointermediate lobe on beta-endorphin synthesis.

In most regimens proposed for the depletive management of cirrhosis of the liver, spirolactone is associated with other diuretics. Treatment of 28 patients with uncompensated forms by means of spirolactone only, using high, protracted doses determined essentially in accordance with the depletion obtained, is described. The disappearance of signs of water retention was gradual and unattended by difficulties. Normalisation of the urinary Na/K ratio preceded the diuretic response; Increased diuresis led to a slight increase in urinary potassium/day. Higher doses were used in patients with lower urinary Na/K ratios. Here a critical diuretic response was only obtained around the 5th day. Transient low blood sodium and chlorine and high blood potassium were noted; the last parameter was not related to the drug dose, nor to changes in Bun; No marked changes in blood uric acid, calcium, ammonium, bilirubin or sugar were observed.

We studied rat distal colon during in vitro incubation with aldosterone and dexamethasone. Both hormones caused short-circuit current (Isc) to increase with a latency period of approximately 3 h. At the 7th h of incubation, control colons had a Isc of 72 +/- 8 microA . cm-2 while tissues incubated with 10(-5) M aldosterone and 10(-8) M dexamethasone, the respective maximal stimulatory concentrations, had similarly increased Isc, 211 +/- 21 and 185 +/- 18 microA . cm-2, respectively. The increase in Isc induced by steroids reflected increased net sodium transport: control, 3.4 +/- 0.8; aldosterone, 6.7 +/- 0.7 (P less than 0.05); and dexamethasone, 7.5 +/- 1.0 mueq . h-1 . cm-2 (P less than 0.025). Spironolactone inhibited buy aldactone the response to both steroids, but the molar ratio of antagonist to agonist was less for aldosterone (approximately 5,000:1) than for dexamethasone (approximately 50,000:1). Amiloride inhibited a greater fraction of aldosterone-induced Isc (0.70 +/- 0.07) than that of dexamethasone (0.37 +/- 0.07; P less than 0.025). The latter value was similar to the effect of amiloride on control tissues (0.35 +/- 0.04). These data provide evidence that the cellular mechanisms by which aldosterone and dexamethasone induce Na+ transport are different.

A clinical pharmacological study was carried out with 11 patients suffering from hepatogeneous ascites. After pretreatment with spironolactone (twice daily 100 mg), 80 mg of a new loop diuretic, muzolimine, were administered orally in addition to 100 mg of spironolactone. The diuretic effect started rapidly, reached its maximum about 6 h after administration and declined slowly until 24 h. The electrolyte profile showed a pronounced excretion of sodium and chloride, whereas potassium excretion was distinctly lower. Sodium/potassium ratio was 5.9 during the first 8 hours, and the mean ratio was 5.2 during 24 hours. Urinary volume and sodium excretion were significantly correlated with plasma levels of muzolimine. Mean plasma half-life of muzolimine in these patients with liver cirrhosis was 7.9 h and was thus longer than in healthy volunteers. Zofran 10 Mg

Extracellular water (EWC; 82-bromide), total body water (TBW; 3-THO), intracellular water (ICW = TBW-ECW), plasma volume (PV; 51-Cr), and total body potassium (TBK; 40-K) were studied in patients with cirrhosis of the liver (n = 12) and in controls (n = 12). ECW (39%), TBW (28%), ICW (19%), and PV (24%) increased, TBK (28%) however, decreased in cirrhosis. The results indicate that it is less the lean body mass, but rather the intracellular potassium concentration that is lowered (cirrhosis: 84 +/- 21 mmol/l ICW; controls: 115 +/- 23 mmol/l ICW). Decreased potassium per cell (mmol) and increased intracellular water are discussed as possible reasons for this. The correlation between TBK (%) and serum potassium (mmol/l) was found to be r = 0.56 (p less than 0.002). Correlations between the biochemical parameters Atarax 30 Mg gamma-globulins, cholin esterase, serum sodium and serum albumin (g/l PV) and characteristic fluid disturbances in cirrhosis are highly significant whereas albumin (g/kg bodyweight) was the same in both groups. We can support the 'overflow theory' of ascites formation.

Cushing's syndrome, an unusual group of disorders characterized by hypercortisolism, must be considered in the differential diagnosis of such common clinical problems as hirsutism, menstrual irregularity, hypertension, diabetes mellitus, and obesity. Its distinct forms--pituitary-dependent Cushing's syndrome (Cushing's disease), adrenal tumor and ectopic ACTH syndrome--must be identified correctly so that specific therapy can be administered. In the majority of cases, use of a relatively simple diagnostic sequence will provide accurate and rapid diagnosis. However, in our experience with more than 60 patients, diagnostic difficulties may arise from a variety of conditions ( Tofranil 25 Mg 50 Drake e.g., drug interference, alcohol ingestion, and depression). In addition, unusual circumstances, such as unexpected responses to dexamethasone, may complicate the diagnosis. Our approach to these problems is illustrated through a report of seven cases, and we emphasize that the proper management of Cushing's syndrome mandates a thorough marshalling of all the available data.

The diagnosis of myasthenia gravis is often difficult and calls for a broader use of pharmacological and electrodiagnostic tests. The decamethonium-edrophonium test, which has proved superior Serevent Diskus Cost to other procedures for this purpose, is based on neurophysiological principles and depicts the behaviour of the neuromuscular junction. A state of resistance to depolarizing agents in the limited form of myasthenia and a state of a non-depolarizing (competitive) block in advanced cases has been shown. This test has demonstrated that the neuromuscular defect exists throughout the skeletal musculature, including muscles clinically unaffected. It produced no false-positive results either in normal or neurasthenic persons or in patients with neurological diseases with myasthenic symptoms. In a patient with botulism and in a patient with ocular palsies from brain-stem encephalitis the edrophonium test gave a false-positive result, while the decamethonium-edrophonium test was negative.Diagnosis, treatment and management of myasthenic emergencies are described.

Many treatment modalities are available to patients with disseminated adenocarcinoma of the prostate. Although no single therapeutic approach can be advocated for all patients at the present time, delay of endocrine manipulation until the onset of symptoms is the recommended approach because it maintains the most normal lifestyle in these patients. With the onset of symptoms such as bone pain or urinary retention, or perhaps as disease progression becomes apparent, orchiectomy is recommended to patients with increased cardiovascular risks as well as to those patients who are judged irresponsible in taking oral estrogens. A dose of 1 mg of diethylstilbestrol three times daily achieves a castrate level Lexapro Medication Dosage of serum testosterone and may not increase cardiovascular mortality. Because of the relative safety and lack of side effects, GnRH analogues represent an alternative treatment in selected patients, particularly in those who refuse orchiectomy or have an increased risk of developing cardiovascular complications. Hormonal manipulation with androgen deprivation remains the cornerstone of treatment and provides clinical remission in the majority of patients with advanced prostate cancer. The prognosis is poor once tumor has recurred. Several secondary forms of endocrine therapy are available, but it would help to be able to select those patients with hormonally sensitive tumors that would respond favorably to these modalities. Transurethral surgery and radiotherapy are effective in palliating patients with bladder outlet obstruction and bony metastases unresponsive to hormonal therapy. Nonhormonal cytotoxic agents are available, but well-controlled studies are required to determine the value of specific agents, whether used alone or in combination.

Spironolactone and cimetidine are effective antiandrogens in vivo, although they differ by five orders of magnitude in affinity for androgen receptors in vitro. To explore this discrepancy, we directly compared the antiandrogenic potency of these two compounds in vivo using the chicken cockscomb topical bioassay. In this assay, the growth of the androgen sensitive cockscomb of immature chicks after stimulation by various doses of androgen (dihydrotestosterone 5, 20, or 100 micrograms/day sc) is inhibited by antiandrogens in cream vehicle applied topically to the cockscomb itself. At low levels of androgen stimulation (5 micrograms/day), 0.5% topical cimetidine produced maximal suppression of cockscomb growth, while at high levels of androgen stimulation 100 micrograms/day), topical cimetidine in concentrations as high as 4% did not suppress cockscomb growth. In contrast, topical spironolactone in concentrations as low as 0.06% produced maximal inhibition of cockscomb growth at all androgen doses. Using an intermediate androgen dose (20 micrograms/day), the minimally effective antiandrogenic concentration of topical cimetidine was between 0.5 and 1.0%, while that for topical spironolactone was less than 0.001%. We conclude that the chicken cockscomb topical bioassay is a useful method for assessing relative potency of antiandrogens. With this method, spironolactone appears to be at least 500 times as strong an antiandrogen in vivo as cimetidine.

In this article, we review the evidence supporting the use of eplerenone for improving cardiovascular prognosis. Activation of the renin-angiotensin-aldosterone system plays a major role in the pathogenesis of heart disease, and blockage of this system has been shown to improve prognosis in several cardiovascular conditions. The 2 marketed aldosterone antagonists, spironolactone and eplerenone, improve prognosis in patients with left ventricular (LV) dysfunction and are effective antihypertensive medications. In addition, a potential role for aldosterone antagonists in the treatment of patients with heart failure and preserved LV function has been suggested and is currently being evaluated in clinical trials. In patients with myocardial infarction having LV dysfunction and evidence of heart failure, eplerenone improves cardiovascular outcomes and attenuates myocardial remodeling. In addition, eplerenone is effective for the treatment of hypertension, where it regresses both LV hypertrophy and proteinuria (2 powerful markers of increased cardiovascular risk). In contrast to spironolactone, eplerenone essentially lacks the sexual side effects that sometimes limit the use of spironolactone. Hyperkalemia is the main potential side effect of eplerenone, especially when used in combination with other medications that can cause hyperkalemia. Adequate patient selection and monitoring are therefore of utmost importance when using this medication. In conclusion, eplerenone is a medication that offers the cardiovascular therapeutic and prognostic benefits of aldosterone antagonism but with fewer side effects compared to spironolactone.

The discovery of compounds possessing antiandrogenic activities has led to their utilization in the treatment of hirsutism of various aetiologies. Spironolactone generally lowers the plasma testosterone by altering its formation and metabolism as well as by decreasing its blood production rate; the medication also contributes to increase the peripheral conversion of testosterone to oestradiol. A major action is that spironolactone inhibits androgen binding to receptor molecules in the cytosol or the nucleus of target tissues such as the skin. During the last five years, we have studied over 450 cases of hirsutism. Approximately 80% of these women were treated with spironolactone alone or in association with dexamethasone (2.5%) or an oral contraceptive (15%). Hirsutism was classified according to Lorenzo (1970). Good to very good clinical results were observed in 80% of the patients who were under study for a minimum of 3 to 4 years. Adverse side-effects were recorded in less than 5% of our group of patients. On the basis of our data and our clinical experience, we conclude that spironolactone is an effective drug in the treatment of female hirsutism.

We designed a three-phase, consecutive, randomised, controlled, double-blind, cross-over pilot study to assess the effects of losartan alone (50 mg/day), spironolactone (25 mg/day) with angiotensin converting enzyme (ACE) inhibitor and, finally, losartan with spironolactone, on HRV and QT dispersion. We enrolled eight patients (aged 47 to 72 years, mean = 63.7 years), with New York Heart Association (NYHA) class II-III heart failure and ejection fraction (EF) < 35%, in the study at a university-affiliated hospital in Dundee, Scotland. Digital 24-hour Holter recordings were analysed for time-domain HRV and the 12-lead ECG was optically scanned and digitised for analysis of QT dispersion. Evaluations were done at baseline, and at six, 12 and 18 weeks from baseline.

Several derivatives of the highly active aldosterone antagonists dihydrospirorenone (2) and spirorenone (3) were synthesized. The purpose of these efforts was to prepare compounds exhibiting reduced endocrinological properties with the same or better aldosterone antagonistic activity than that of spirorenone. The 1 alpha,2 alpha-methylene derivative 20 has a similar aldosterone antagonistic potency compared to that of spirorenone but does not show decreased endocrinological side effects. Other substituents as in compounds 4-11, 15-19, and 21 sharply decreased the aldosterone antagonistic activity of 2 or 3, respectively.

A total of 6,632 patients with LVSD and heart failure after AMI were randomized to eplerenone or placebo and followed for a mean of 16 months. The co-primary endpoints were all-cause death and the composite of cardiovascular death/cardiovascular hospitalization. The evaluation of resource use included hospitalizations, outpatient services, and medications. Survival beyond the trial period was estimated using data from the Framingham Heart Study, the Saskatchewan Health database, and the Worcester Heart Attack Registry. The incremental cost-effectiveness of eplerenone in cost per life-year and quality-adjusted life-year gained was estimated. The perspective of the Swiss third party payers was used. Daily treatment costs of eplerenone were set at CHF 3.88. All other resources were valued on the basis of official tariffs. Discounting of the results was performed at a rate of 3%.

Guinea pig aorta rings repeatedly stimulated with phenylephrine (1 microM) in the presence of Krebs solution containing ouabain (0.8 microM) or low K+ (0.5 mM) concentration produced an increase in basal tone. This effect is due to an increase in intracellular Ca2+ as a consequence of Na(+)-K+ATPase pump inhibition induced by receptorial (ouabain) or ion imbalance (low K+) mechanism. We investigated the effect of spironolactone and its metabolites canrenone and potassium canrenoate on the increase in basal tone of guinea pig aorta rings. Spironolactone, canrenone, and potassium canrenoate, in a concentration-dependent manner (3-30 microM), inhibited the increase in basal tone induced by ouabain, most likely acting as antagonist for ouabain binding site on Na(+)-K+ATPase pump. Indeed, this effect appears to be a feature of these drugs since structurally related drugs, such as aldosterone and hydrocortisone, were ineffective. Conversely, all the drugs tested reduced, to a certain degree, the increase in basal tone produced by low K+ Krebs solution, implying that this could be a non-specific effect. Our results may indicate that spironolactone, canrenone, and potassium canrenoate act in hypertension by interfering with mechanisms in which an ouabain-like factor is involved.

Canrenone attenuated LV dilation and interstitial remodeling, and improved LV filling dynamics and systolic function in the rat model of postinfarction heart failure. Addition of ramipril conferred further cardioprotection. Canrenone also reduced myocardial norepinephrine content and increased ventricular fibrillation threshold. The data provide a potential explanation for the decreased sudden death observed in the RALES study. The mechanisms of action of aldosterone inhibition are still poorly understood, despite its proven efficacy in heart failure. Rats with postinfarction heart failure were randomized to receive for 1 month either no drug or canrenone, or ramipril, or a combination of canrenone and ramipril. Canrenone treatment was associated with a significant attenuation of LV dilation, better LV diastolic and systolic dynamics, and a marked reduction of reactive fibrosis. These effects were enhanced by concomitant ramipril therapy. Moreover, canrenone increased ventricular fibrillation threshold and reduced myocardial norepinephrine content. The data may explain the reduced mortality demonstrated by the RALES.

Losartan treatment prevented significant RGC loss (median loss = 2.5%, p = 0.13), while median loss with water, spironolactone, and enalapril treatments were 26%, 28% and 43%; p < 0.0001). The lower RGC loss with losartan was significantly less than the loss with spironolactone or enalapril (regression model p = 0.001; drug treatment group term p = 0.01). Both losartan and enalapril significantly lowered blood pressure (p< 0.001), but losartan was protective, while enalapril led to worse than water-treated RGC loss. RGC loss after crush injury was unaffected by losartan treatment (difference from control p = 0.9). Survival of RGC in cell culture was not prolonged by sartan treatment. Axonal transport blockade after 3 day IOP elevations was less in losartan-treated than in control glaucoma eyes (p = 0.007). Losartan inhibited effects of glaucoma, including reduction in extracellular signal-related kinase activity and modification of glaucoma-related changes in scleral thickness and creep under controlled IOP.
