RESUMO

OBJECTIVE: This study aims to estimate the cost-effectiveness of oral spironolactone plus routine topical treatment compared with routine topical treatment alone for persistent acne in adult women from a British NHS perspective over 24 weeks. DESIGN: Economic evaluation undertaken alongside a pragmatic, parallel, double-blind, randomised trial. SETTING: Primary and secondary healthcare, community and social media advertising. PARTICIPANTS: Women ≥18 years with persistent facial acne judged to warrant oral antibiotic treatment. INTERVENTIONS: Participants were randomised 1:1 to 50 mg/day spironolactone (increasing to 100 mg/day after 6 weeks) or matched placebo until week 24. Participants in both groups could continue topical treatment. MAIN OUTCOME MEASURES: Cost-utility analysis assessed incremental cost per quality-adjusted life year (QALY) using the EQ-5D-5L. Cost-effectiveness analysis estimated incremental cost per unit change on the Acne-QoL symptom subscale. Adjusted analysis included randomisation stratification variables (centre, baseline severity (investigator's global assessment, IGA <3 vs ≥3)) and baseline variables (Acne-QoL symptom subscale score, resource use costs, EQ-5D score and use of topical treatments). RESULTS: Spironolactone did not appear cost-effective in the complete case analysis (n=126 spironolactone, n=109 control), compared with no active systemic treatment (adjusted incremental cost per QALY £67 191; unadjusted £34 770). Incremental cost per QALY was £27 879 (adjusted), just below the upper National Institute for Health and Care Excellence's threshold value of £30 000, where multiple imputation took account of missing data. Incremental cost per QALY for other sensitivity analyses varied around the base-case, highlighting the degree of uncertainty. The adjusted incremental cost per point change on the Acne-QoL symptom subscale for spironolactone compared with no active systemic treatment was £38.21 (complete case analysis). CONCLUSIONS: The results demonstrate a high level of uncertainty, particularly with respect to estimates of incremental QALYs. Compared with no active systemic treatment, spironolactone was estimated to be marginally cost-effective where multiple imputation was performed but was not cost-effective in complete case analysis. TRIAL REGISTRATION NUMBER: ISRCTN registry (ISRCTN12892056).

RESUMO

A range of treatment options are available for both mild to moderate and moderate to severe acne, and these options vary widely in their clinical uses, effectiveness, and costs. With the continued rise of dermatologic drug prices and increased cost-sharing due to high-deductible health plans, the importance of cost-effective treatment continues to grow. Failure to consider cost-effective, patient-centered care may lead to increased financial toxicity, reduced adherence, and ultimately worse outcomes and patient satisfaction. Combination topical products offer improved efficacy and convenience, which are associated with better adherence and outcomes. Generic fixed-dose adapalene-benzoyl peroxide (BPO) and fixed-dose clindamycin-BPO can be highly cost-effective options for patients with mild to moderate acne. Hormonal agents such as combined oral contraceptives (COCs) and spironolactone are inexpensive and likely reflect a highly cost-effective option that could reduce reliance on oral antibiotics in patients with moderate to severe acne. Doxycycline and isotretinoin also are cost-effective options for more severe acne. Frequent laboratory monitoring for spironolactone and isotretinoin continues to be prevalent despite little evidence to support its clinical utility, and it is associated with a major cost burden to the patient and health care system. The reduction of laboratory monitoring is an opportunity to provide higher-value care.

RESUMO

Value-based care is the foundation of population health. The Health care Economic Efficiency Ratio (HEERO) scoring system is a promising new tool to measure the cost benefits of care in our Accountable Care Organization. HEERO score compares actual costs spent (utilizing insurance claims) and expected costs spent (estimated using the Centers for Medicare/Medicaid Services Risk score). Scores <1 suggest economic benefit. Sacubitril/valsartan has been shown to decrease readmissions for patients with heart failure (HF) and decrease health care costs. We explored the utility of sacubitril/valsartan in reducing HEERO scores and decreasing overall health care expenditure in patients with HF. Patients with HF in the population health cohort were enrolled. HEERO score was calculated for patients taking sacubitril/valsartan and other HF medications at 3-month intervals up to a year. We compared the average and total health care expenditure and inpatient days for patients on sacubitril/valsartan, spironolactone, ß blocker (BB) along with spironolactone, BB and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. For patients on sacubitril/valsartan, HEERO scores and inpatient days decreased (decreased health care expenditure) as the number of days of utilization increased (p <0.0001). In total, 270+ days of sacubitril/valsartan decreased health care costs by 22%. This cost reduction was mainly attributed to decreased inpatient days. Additionally, the combination of sacubitril/valsartan, spironolactone, and BB showed decreased HEERO score and inpatient days compared with spironolactone, BB and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker in male patients. Sacubitril/valsartan use beyond 270 days resulted in decreased health care expenditure in a population health cohort compared with other HF medications. This economic benefit is achieved through the reduction in hospitalizations. Sacubitril/valsartan is an integral part of value-based care providing high-value, cost-effective care, and bolstering the economic wellbeing of patient care. Payor sources should consider this in subsidizing the cost of the medicine.

RESUMO

BACKGROUND: The objective of our study is to evaluate the efficacy and safety of mineralocorticoid receptor antagonists (MRAs) and determine the optimal MRA treatment regimen in patients with chronic kidney disease (CKD). METHODS: We searched PubMed, Embase, Web of Science, and the Cochrane Library from their inception to June 20, 2022. The composite kidney outcome, cardiovascular events, urinary albumin to creatinine ratio (UACR), estimated glomerular filtration rate (EGFR), serum potassium, systolic blood pressure (SBP), diastolic blood pressure (DBP), creatine and creatine clearance were included for analysis. We conducted pairwise meta-analyses and Bayesian network meta-analyses (NMA) and calculated the surface under the cumulative ranking curve (SUCRA). RESULTS: We included 26 studies with 15,531 participants. By pairwise meta-analyses, we found that MRA treatment could significantly reduce UACR in CKD patients with or without diabetes. Notably, compared to placebo, Finerenone was associated with a lower risk of composite kidney outcome and cardiovascular events. Data from NMA demonstrated an overt UACR reduction without increasing serum potassium by Apararenone, Esaxerenone, and Finerenone in CKD patients. Spironolactone decreased SBP and DBP but elevated CKD patients' serum potassium. CONCLUSIONS: Compared to placebo, Apararenone, Esaxerenone, and Finerenone might ameliorate albuminuria in CKD patients without causing elevated serum potassium levels. Remarkably, Finerenone conferred a cardiovascular benefit, and Spironolactone lowered blood pressure in CKD patients.

RESUMO

AIMS: The HOMAGE randomized trial found that spironolactone reduced left atrial volume index (LAVI), E:A ratio, and a marker of collagen type I synthesis (procollagen type I C-terminal propeptide) in patients at risk of heart failure (HF). Previous trials showed that patients with HF, preserved ejection fraction and low serum collagen type I C-terminal telopeptide to matrix metalloproteinase-1 ratio (CITP:MMP-1), associated with high collagen cross-linking, had less improvement in diastolic function with spironolactone. We evaluated the interaction between serum CITP:MMP-1 and spironolactone on cardiac function in the HOMAGE trial. METHODS AND RESULTS: Patients at risk of HF were randomized to spironolactone (n = 260) or not (n = 255). Blood sampling and echocardiography were done at baseline, one and nine months. CITP:MMP-1 was used as an indirect measure of collagen cross-linking. Higher baseline CITP:MMP-1 (i.e. lower collagen cross-linking) was associated with greater reductions in LAVI with spironolactone at both one (p = 0.003) and nine (p = 0.01) months, but no interaction was observed for E:A ratio. Spironolactone reduced LAVI after one and nine months only for those patients in the third tertile of CITP:MMP-1 (estimated lowest collagen cross-linking) [mean differencesspiro/control : -1.77 (95% confidence interval, CI -2.94 to -0.59) and -2.52 (95% CI -4.46 to -0.58) mL/m2 ; interaction pacross-tertiles  = 0.005; interaction pthird tertile  = 0.008] with a similar trend for N-terminal pro-B-type natriuretic peptide which was consistently reduced by spironolactone only in the lowest collagen cross-linking tertile [mean differencesspiro/control : -0.47 (95% CI -0.66 to -0.28) and -0.31 (95% CI -0.59 to -0.04) ng/L; interaction pacross-tertiles  = 0.09; interaction pthird tertile < 0.001]. CONCLUSIONS: These findings suggest that, for patients at risk of HF, the effects of spironolactone on left atrial remodelling may be more prominent in patients with less collagen cross-linking (indirectly assessed by serum CITP:MMP-1).

RESUMO

BACKGROUND AND AIMS: Potassium-wasting (loop diuretics [LD]) and potassium-sparing (spironolactone) medications used for heart failure (HF) may alter renal potassium handling and confound the use of twenty-four-hour (24-h) urine collections as a surrogate marker for potassium intake, an effect that has been observed with dietary sodium assessment. The objective was to determine the strength of association between 24-h urine collections and weighed food records in assessing potassium intake in HF patients stratified by LD usage and spironolactone usage. METHODS AND RESULTS: Stable outpatients with HF simultaneously completed two 24-h urine collections and two weighed food records on consecutive days. Analyses compared patients stratified by LD and/or spironolactone use. Pearson's correlation and the Bland-Altman method of agreement assessed the relationship between the techniques. Overall, 109 patients (61 ± 11 yrs, 74% male) were included. The mean difference in dietary potassium estimated between 24-h urine collections and food records was -353 ± 1043 mg (p < 0.01) for all patients, with no differences between measures among subgroups. The association between the two methods was r = 0.551 (95% CI, 0.373 to 0.852, p < 0.001) for LD users; r = 0.287 (95% CI, 0.01 to 0.570, p = 0.050) for LD non-users; r = 0.321 (95% CI, 0.13 to 0.798, p = 0.043) for spironolactone users, and; r = 0.534 (95% CI, 0.331 to 0.747, p < 0.001) for spironolactone non-users. There were no significant mean biases identified as part of the Bland-Altman analysis. CONCLUSION: Among HF patients, potassium-wasting and potassium-sparing medications do not influence the agreement between the two methods in the assessment of potassium intake.

RESUMO

BACKGROUND: Limited evidence has indicated that addition of a steroidal mineralocorticoid receptor antagonist (MRA) to the standard of care reduces proteinuria in patients with diabetic kidney disease (DKD); however, there are limited data regarding real-world MRA use in these patients. This study aimed to describe the characteristics of spironolactone users and non-users with DKD, and to explore their clinical outcomes. METHODS: This was a non-interventional, retrospective cohort study using demographic and clinical data from a US claims database (PharMetrics Plus) and the Experian consumer data asset during 2006-2015. Baseline characteristics (e.g. comorbidities) and post-inclusion clinical outcomes were described in matched cohorts of spironolactone users and non-users (n = 5465 per group). RESULTS: Although matching aligned key demographic and clinical characteristics of the cohorts, a significantly greater proportion of spironolactone users than non-users had oedema, proteinuria, and cardiovascular disease at baseline (P < 0.0001). During the post-inclusion period, disease progression and clinical events of interest such as acute kidney injury were more commonly observed in spironolactone users than non-users. Users also had higher healthcare resource utilization and costs than non-users; however, these differences diminished at later stages of disease. CONCLUSIONS: In this study, spironolactone users had a greater comorbidity burden at baseline than matched non-users, suggesting that the presence of certain comorbidities may be contributing factors in the decision to prescribe spironolactone. High healthcare resource utilization and costs for patients at later stages of disease, irrespective of spironolactone use, highlight the need for new therapies for DKD.

RESUMO

AIMS: Improvement in left ventricular (LV) systolic reserve, including exertional increase in global longitudinal strain (GLS), may contribute to the clinical benefit from therapeutic interventions in heart failure with preserved ejection fraction (HFpEF). However, GLS is an afterload-dependent parameter, and its measurements may not adequately reflect myocardial contractility recruitment with exercise. The estimation of myocardial work (MW) allows correction of GLS for changing afterload. We sought to investigate the associations of GLS and MW parameters with the response of exercise capacity to spironolactone in HFpEF. METHODS AND RESULTS: We analysed 114 patients (67 ± 8 years) participating in the STRUCTURE study (57 randomized to spironolactone and 57 to placebo). Resting and immediately post-exercise echocardiograms were performed at baseline and at 6-month follow-up. The following indices of MW were assessed: global work index (GWI), global constructive work (GCW), global wasted work, and global work efficiency. The amelioration of exercise intolerance at follow-up in the spironolactone group was accompanied by a significant improvement in exertional increase in GCW (P = 0.002) but not in GLS and other MW parameters. Increase in exercise capacity at 6 months was independently correlated with change in exertional increase in GCW from baseline to follow-up (ß = 0.24; P = 0.009) but not with GLS (P = 0.14); however, no significant interaction with the use of spironolactone on peak VO2 was found (P = 0.97). CONCLUSION: GCW as a measure of LV contractile response to exertion is a better determinant of exercise capacity in HFpEF than GLS. Improvement in functional capacity during follow-up is associated with improvement in exertional increment of GCW.

RESUMO

Resistant hypertension is defined as uncontrolled blood pressure (BP) despite three antihypertensive agents including a diuretic (thiazide diuretic if renal function is normal or loop diuretic in case of chronic kidney disease with eGFR<30mL/min), a renin-angiotensin system blocker (ARB or ACEI) and a calcium channel blocker, at optimal doses. Resistance must be confirmed by out-of-office measurements (ambulatory blood pressure monitoring or home blood pressure monitoring) and patients should be asked about treatment compliance and excessive salt or alcohol intake. If the diagnosis of resistant hypertension is confirmed, the patient should be referred to a hypertension specialist to screen for secondary causes of hypertension as they are frequent in this context. If essential resistant hypertension is confirmed, the mineralocorticoid receptor antagonist, spironolactone, should be added (25 to 50mg daily). In the event of a contraindication to spironolactone, or if adverse effects occur, a beta-blocker, an alpha-blocker, or a centrally acting antihypertensive drug should be prescribed.

RESUMO

PURPOSE OF REVIEW: 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. RECENT FINDINGS: Evidence has accumulated that resistant HTN is generally volume-dependent, attributable to varying degrees of aldosterone excess with its attendant renal effects of sodium and fluid retention. Such aldosteronism may be due to an underestimated occurrence of primary aldosteronism; however, it more commonly occurs separately from it and independent from angiotensin II. The aldosterone-induced volume excess placed at the root of the development of resistant HTN in a large number of patients, together with the extrarenal deleterious effects of aldosterone, such as endothelial dysfunction, vascular remodeling and increased arterial stiffness, cardiac hypertrophy, and fibrosis can all be counterbalanced by the administration of MRAs. In the absence of a direct comparison between spironolactone and eplerenone, and in light of compelling evidence provided by the recently reported results of the PATHWAY-2 and ReHOT studies, spironolactone has been established as the most effective add-on anti-aldosterone therapy in resistant HTN. The data on use of eplerenone continue to emerge and are quite encouraging. Despite the lack of direct comparative data, the weight of evidence regarding efficacy is currently in favor of spironolactone. However, the data on the efficacy of eplerenone are promising but still being accumulated suggesting this agent as an alternative to spironolactone and certainly as the preferred choice for those not tolerating spironolactone, especially for patients developing anti-androgenic side effects like breast tenderness, gynecomastia/mastodynia, and/or sexual dysfunction. Both these agents appear to have several other pleiotropic effects that confer cardioprotection and renoprotection beyond their antihypertensive effect. Potassium levels and renal function need to be closely monitored during administration of these therapies. Future comparative studies may shed more light on these issues, while emerging newer agents may offer better and safer therapeutic options.

RESUMO

BACKGROUND: Therapy with evidence-based heart failure (HF) medications has been shown to be associated with lower risk of 30-day all-cause readmission in patients with HF and reduced ejection fraction (HFrEF). METHODS: We examined the association of aldosterone antagonist use with 30-day all-cause readmission in this population. Of the 2443 Medicare beneficiaries with HF and left ventricular EF ≤35% discharged home from 106 Alabama hospitals during 1998-2001, 2060 were eligible for spironolactone therapy (serum creatinine ≤2.5 for men and ≤2mg/dl for women, and serum potassium <5mEq/L). After excluding 186 patients already receiving spironolactone on admission, the inception cohort consisted of 1874 patients eligible for a new discharge prescription for spironolactone, of which 329 received one. Using propensity scores for initiation of spironolactone therapy, we assembled a matched cohort of 324 pairs of patients receiving and not receiving spironolactone balanced on 34 baseline characteristics (mean age 72years, 42% women, 33% African American). RESULTS: Thirty-day all-cause readmission occurred in 17% and 19% of matched patients receiving and not receiving spironolactone, respectively (hazard ratio [HR], 0.92; 95% confidence interval [CI], 0.64-1.32; p=0.650). Spironolactone had no association with 30-day all-cause mortality (HR, 0.84; 95% CI, 0.38-1.88; p=0.678) or HF readmission (HR, 0.74; 95% CI, 0.41 1.31; p=0.301). These associations remained unchanged during 12months of post-discharge follow-up. CONCLUSION: A discharge prescription for spironolactone had no association with 30-day all-cause readmission among older, hospitalized Medicare beneficiaries with HFrEF eligible for spironolactone therapy.

RESUMO

BACKGROUND: Eplerenone has been demonstrated as being cost effective for the treatment of patients with systolic heart failure (HF) and mild symptoms in several jurisdictions; however, its cost effectiveness is unknown in the context of Alberta, Canada. METHODS: We used a discrete-event simulation model to compare costs and outcomes between standard care and standard care plus eplerenone for the treatment of HF with mild symptoms. We used Alberta data (whenever possible) together with a healthcare perspective, a lifetime horizon, and 3 % annual discount rate for analyses. RESULTS: Clinically, eplerenone prevented HF hospitalizations, atrial fibrillations, and cardiovascular (CV) deaths, but incurred more adverse events and device implantations than standard care. The remaining life of patients receiving eplerenone was 7.08 versus 5.83 years for those receiving standard care. Eplerenone gained 1.25 life-years and 1.18 quality-adjusted life-years (QALYs), with an incremental cost of $Can7200. Therefore, the incremental cost-effectiveness ratio (ICER) was $Can5700 per life-year gained and $Can6100 per QALY gained. CONCLUSIONS: Given the most cited ICER threshold is $Can50,000, the use of eplerenone as an adjunct to standard care for treating patients with systolic HF and mild symptoms is cost effective in the context of Alberta. Eplerenone would cost the Alberta health system about $Can4.6 million a year in drug costs. Incorporating reductions in health services utilization associated with eplerenone, the budget impact is smaller. For the first year, the use of eplerenone is cost saving and for 5 years the cost is approximately $Can6 million.

RESUMO

The objective of this study was to determine the cost-effectiveness of eplerenone compared with usual care in patients with chronic heart failure and New York Heart Association (NYHA) Class II symptoms.A Markov model was constructed with 5 health states to reflect NYHA symptom status (Classes I-IV) and death. All subjects began in the "Class II" health state and then moved to other symptom health states or died. Subjects could also be hospitalized for HF in any cycle. Transition probabilities were derived from the Eplerenone in Mild Patients Hospitalization And Survival Study in Heart Failure (EMPHASIS-HF) study. Decision analysis was applied to compare an Eplerenone Group with a Usual Care Group (UCG). In the UCG, 47.3% of subjects in Class II and 93.7% of subjects in Classes III and IV were assumed to be taking spironolactone (as per published data). In the Eplerenone Group, all subjects in Classes II, III, and IV were assumed to be taking eplerenone. The efficacy of spironolactone was assumed to be the same as eplerenone. Cost and utility data were derived from published sources. A discount rate of 5.0% was applied to future costs and benefits. The outcome of interest was incremental cost-effectiveness ratio (ICER) (cost per year of live saved (YoLS) and quality-adjusted life years (QALY) gained).Over 10 years the model predicted that for each patient compared with usual care, eplerenone would lead to 0.26 YoLS (discounted) and 0.19 QALYs gained (discounted), at a net cost of AUD $6961 (discounted). These equate to ICERs of AUD 28,001 per YoLS and AUD 37,452 per QALY gained. Sensitivity analyses indicated a 99.0% likelihood of eplerenone being cost-effective compared with usual care at a willingness to pay threshold of AUD 50,000 per QALY gained.From an Australian healthcare perspective, the addition of eplerenone in management of patients with chronic heart failure and NYHA Class II symptoms represents a cost-effective strategy compared with usual care.

RESUMO

BACKGROUND: While aldosterone antagonists have proven benefit among post-myocardial infarction (MI) patients with low ejection fraction (EF), how this treatment is used among older MI patients in routine practice is not well described. METHODS AND RESULTS: Using ACTION Registry-GWTG linked to Medicare data, we examined 12 080 MI patients ≥65 years with EF ≤40% who were indicated for aldosterone antagonist therapy per current guidelines and without documented contraindications. Of these, 11% (n=1310) were prescribed aldosterone antagonists at discharge. Notably, 10% of patients prescribed an aldosterone antagonist were eligible for, but not concurrently treated with, an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. Spironolactone was the predominantly prescribed aldosterone antagonist. At 2-year follow-up, aldosterone antagonist use was not associated with lower mortality (unadjusted 39% versus 38%; HR 0.99, 95% CI 0.88-1.33 using inverse probability-weighted propensity adjustment) except in symptomatic HF patients (HR 0.84, 95% CI 0.72-0.99, Pinteraction=0.009). Risks of hyperkalemia were low at 30 days, but significantly higher among patients prescribed aldosterone antagonists (unadjusted 2.3% versus 1.5%; adjusted HR 2.04, 95% CI 1.16-3.60), as was 2-year risk of acute renal failure (unadjusted 6.7% versus 4.8%; adjusted HR 1.39, 95% CI 1.01-1.92) compared with patients not prescribed aldosterone antagonists. CONCLUSIONS: Aldosterone antagonist use among eligible older MI patients in routine clinical practice was not associated with lower mortality except in patients with HF symptoms, but was associated with increased risks of hyperkalemia and acute renal failure. These results underscore the importance of close post-discharge monitoring of this patient population.

RESUMO

OBJECTIVE: to elucidate significance of regulatory adaptive status (RAS) for assessment of effectiveness of medical treatment and prediction of cardiovascular complications in functional class (FC) III congestive heart failure (CHF). MATERIAL AND METHODS: We included into this study 100 patients with hypertensive disease (HD) or ischemic heart disease (IHD) and FC III CHF with compromised systolic left ventricular (LV) function. All patients were randomized into two groups. In addition to complex background therapy (quinapril, torasemide, spironolactone) patients of group 1 (n=56, age 57.5+/-21.7 years) were given metoprolol succinate (59.1+/-12.1 mg/day) and patients of group 2 (n=44, age 57.1+/-21.4 years) - ivabradine (12.1+/-4.6 mg/day). Examination at baseline and after 6 months included cardiorespiratory synchronism test (in order to quantitatively define RAS), echocardiography, treadmill test, six minute walk test. Cardiovascular complications (CVC) were registered during 12 months of study treatment. RESULTS: Both schemes of complex therapy equally improved structural and functional state of the myocardium, increased tolerance to physical exercise, reduced neurohumoral hyperactivation. Positive impact on RAS was more pronounced in ivabradine group. Clinical efficacy of therapy as well as number of hospitalizations because of CHF decompensation, ischemic strokes, and cardiovascular deaths did not differ substantially between groups. Initially low or unsatisfactory RAS was associated with higher incidence of CVC while initial unsatisfactory RAS was associated with elevated risk of sudden death. CONCLUSION: The data obtained reflect independent value of determination of RAS for assessment of efficacy of pharmacotherapy and prognosis of CVC in patients with FCIII CHF.

RESUMO

BACKGROUND: Spironolactone, the only aldosterone antagonist available in China, improves outcomes in acute myocardial infarction (AMI) among patients with systolic dysfunction and either diabetes or heart failure (HF). However, national practice patterns in the use of spironolactone in China are unknown. METHODS AND RESULTS: From a nationally representative sample of AMI patients from in 2001, 2006, and 2011, we identified 6906 patients with either diabetes or HF and classified them into 1 of 4 groups according to their eligibility for spironolactone-"ideal"(left ventricular ejection fraction [LVEF] ≤40% and without contraindications), "contraindicated," "not indicated" (neither ideal nor contraindicated), and "unknown indications" (LVEF unmeasured)-to determine how frequently patient eligibility for this drug is assessed in the hospital, how it is used in several groups, and to identify factors associated with the use in these groups. From 2001 to 2011, the proportion of patients whose eligibility for spironolactone was not assessed decreased (66.9% in 2001 to 32.8% in 2011). Spironolactone use significantly increased among ideal patients over this period (28.6% to 72.4%; P<0.001 for trend), but also in contraindicated patients (11.4% to 27.5%; P=0.002 for trend) and in other patients groups (not indicated: 27.5% to 38.3%; unknown indications: 21.3% to 35.1%; both P<0.01 for trend). In all 4 groups, patients presenting with HF on admission were more likely to receive spironolactone. CONCLUSIONS: Although the appropriate use of spironolactone and assessment of eligibility increased in China over the past decade, there remains marked opportunities for improvement.

RESUMO

Acne vulgaris is a very common condition affecting up of 93% of adolescents. Although rare, this disease may persist in adulthood. In adult women with acne (those older than 25 years old), this condition is particularly relevant because of the refractory to conventional therapies, which makes acne a challenge for dermatologists in this group of patients. In order to its potential risk for chronicity and the involvement of visible anatomical sites such as face and upper torso, acne has been associated with a wide spectrum of psychological and social dysfunction such as depression, anxiety, suicidal ideation, somatization, and social inhibition. In particular, adult women with acne have been shown to be adversely impacted by the effect of acne on their quality of life. For the last four decades, dermatologists have used hormonal therapies for the management of acne vulgaris in adult women, which are considered a rational choice given the severity and chronicity of this condition in this group of patients. The aim of this work is to review the hormonal drugs for management of acne.

RESUMO

PURPOSE: Clinical trials and few observational studies report increased hyperkalemia risks in heart failure patients receiving aldosterone blockers in addition to standard therapy. The aim of this study is to assess the hyperkalemia risk and combined use of spironolactone and long-term ACE (angiotensin-converting enzyme) inhibitor/angiotensin receptor blocker (ARB) therapy for heart failure in a real-life setting of a heterogeneous population. METHODS: Using claims data of the statutory health insurance fund AOK, covering 30% of the German population, we performed a nested case-control study in a cohort of heart failure patients receiving continuous ACE/ARB therapy (n = 1,491,894). Hyperkalemia risk associated with concurrent use of spironolactone and ACE/ARB was calculated by conditional logistic regression in 1062 cases and 10,620 risk-set-sampling-matched controls. RESULTS: Risk of hyperkalemia in heart failure patients was significantly associated with spironolactone use (odds ratio (OR) (95% confidence interval (CI)) = 13.59 (11.63-15.88) in all and 11.05 (8.67-14.08) in those with information on New York Heart Association (NYHA) stage of disease). In the NYHA subpopulation, higher risk estimates were observed in short-term as compared with long-term users (OR (95%CI) = 13.00 (9.82-17.21) and 9.12 (6.78-12.26), respectively). Moreover, the association was stronger in older (≥70 years of age) as compared with younger patients (<70 years of age) (OR (95%CI) = 12.32 (9.35-16.23) and 8.73 (5.05-15.08), respectively), although interaction was not significant (pinteraction = 0.07). CONCLUSIONS: Hyperkalemia risk associated with combined use of spironolactone and ACE/ARB is much stronger in real-life practice than observed in clinical trials. Careful potassium level monitoring in concomitant users of spironolactone and ACE/ARB is necessary.

RESUMO

BACKGROUND: Nearly 50% of patients with heart failure (HF) have preserved LV ejection fraction, with interstitial fibrosis and cardiomyocyte hypertrophy as early manifestations of pressure overload. However, methods to assess both tissue characteristics dynamically and noninvasively with therapy are lacking. We measured the effects of mineralocorticoid receptor blockade on tissue phenotypes in LV pressure overload using cardiac magnetic resonance (CMR). METHODS AND RESULTS: Mice were randomized to l-nitro-ω-methyl ester (l-NAME, 3 mg/mL in water; n=22), or l-NAME with spironolactone (50 mg/kg/day in subcutaneous pellets; n=21). Myocardial extracellular volume (ECV; marker of diffuse interstitial fibrosis) and the intracellular lifetime of water (τic; marker of cardiomyocyte hypertrophy) were determined by CMR T1 imaging at baseline and after 7 weeks of therapy alongside histological assessments. Administration of l-NAME induced hypertensive heart disease in mice, with increases in mean arterial pressure, LV mass, ECV, and τic compared with placebo-treated controls, while LV ejection fraction was preserved (>50%). In comparison, animals receiving both spironolactone and l-NAME ("l-NAME+S") showed less concentric remodeling, and a lower myocardial ECV and τic, indicating decreased interstitial fibrosis and cardiomyocyte hypertrophy (ECV: 0.43 ± 0.09 for l-NAME versus 0.25 ± 0.03 for l-NAME+S, P<0.001; τic: 0.42 ± 0.11 for l-NAME groups versus 0.12 ± 0.05 for l-NAME+S group). Mice treated with a combination of l-NAME and spironolactone were similar to placebo-treated controls at 7 weeks. CONCLUSIONS: Spironolactone attenuates interstitial fibrosis and cardiomyocyte hypertrophy in hypertensive heart disease. CMR can phenotype myocardial tissue remodeling in pressure-overload, furthering our understanding of HF progression.

RESUMO

Although randomized controlled trials have demonstrated benefits of aldosterone antagonists for patients with heart failure and reduced ejection fraction (HFrEF), they excluded patients with serum creatinine >2.5 mg/dl, and their use is contraindicated in those with advanced chronic kidney disease (CKD). In the present analysis, we examined the association of spironolactone use with readmission in hospitalized Medicare beneficiaries with HFrEF and advanced CKD. Of the 1,140 patients with HFrEF (EF <45%) and advanced CKD (estimated glomerular filtration rate [eGFR] <45 ml/min/1.73 m(2)), 207 received discharge prescriptions for spironolactone. Using propensity scores (PSs) for the receipt of discharge prescriptions for spironolactone, we estimated PS-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for spironolactone-associated outcomes. Patients (mean age 76 years, 49% women, 25% African-American) had mean EF 28%, mean eGFR 31 ml/min/1.73 m(2), and mean potassium 4.5 mEq/L. Spironolactone use had significant PS-adjusted association with higher risk of 30-day (HR 1.41, 95% CI 1.04 to 1.90) and 1-year (HR 1.36, 95% CI 1.13 to 1.63) all-cause readmissions. The risk of 1-year all-cause readmission was higher among 106 patients with eGFR <15 ml/min/1.73 m(2) (HR 4.75, 95% CI 1.84 to 12.28) than among those with eGFR 15 to 45 ml/min/1.73 m(2) (HR 1.34, 95% CI 1.11 to 1.61, p for interaction 0.003). Spironolactone use had no association with HF readmission and all-cause mortality. In conclusion, among hospitalized patients with HFrEF and advanced CKD, spironolactone use was associated with higher all-cause readmission but had no association with all-cause mortality or HF readmission.
