RESUMO

PURPOSE: The correlation between spironolactone usage and cancer risk has sparked interest. The objective of this study is to examine the association between spironolactone use and the incidence of urinary tract cancer in the general population. METHODS: We conducted a matched population-based cohort study. The study population was obtained from the Taiwan National Health Insurance Research Database (TNHIRD) during the period from 2000 to 2016. The multivariate Cox proportional hazard model was performed to examine the impact of spironolactone use on the risk of urinary tract cancer. A total of 8,608 individuals exposed to spironolactone were exact matched by 1:1 ratio with unexposed controls on factors including age, gender, comorbidities, CCI scores and socioeconomic status. The incidences of urinary tract cancer, including prostate, renal and bladder cancer, were estimated in both spironolactone exposed and non-exposed cohorts. RESULTS: After adjusting for confounding variables, the multivariate Cox regression analysis showed no significant association between spironolactone exposure and urinary tract cancer incidence, including bladder (adjusted hazard ratio [aHR] = 1.19, 95% confidence interval [CI] = 0.72-1.96, p = 0.50), renal (aHR = 1.75, 95% CI = 0.99-3.07, p = 0.053), and prostate cancer (aHR = 0.67, 95% CI = 0.43-1.04, p = 0.07). When the population was stratified into low (cumulative dose < = 29,300 mg) and high (cumulative dose >29,300 mg) dose of spironolactone, only high dose of spironolactone use was significantly associated with a reduced risk of prostate cancer (aHR = 0.45, 95% CI = 0.23-0.89, p = 0.02), while being associated with an elevated risk of renal cancer (aHR = 2.09, 95% CI = 1.07-4.08, p = 0.03). However, no clear cumulative dose-response relationship was observed in theses associations. CONCLUSIONS: High cumulative dose of spironolactone may be potentially associated with a decreased incidence of prostate cancer and an increased incidence of renal cancer, while no significant association was observed with bladder cancer incidence. However, given the lack of support from the dose-response pattern, the available evidence is inconclusive to establish a definitive association between spironolactone use and urinary tract cancer.

RESUMO

OBJECTIVE: Spironolactone (SPL) has been used to manage hyperandrogenic manifestations in women with polycystic ovary syndrome (PCOS), but data on the risk of hyperkalemia in this population are scarce. The aim of this study was to evaluate the incidence of hyperkalemia in women with PCOS using SPL in the long term. DESIGN: Single-centre retrospective study. PATIENTS: Inclusion and analysis of 98 treatment periods in 78 women with PCOS (20 of whom were duplicates, returning after treatment interruption for a mean of 38 months) who received SPL for a minimum of 12 months and had at least three measurements of potassium levels over time. MEASUREMENTS: Clinical and hormonal profiles before and during SPL treatment. RESULTS: Mean age was 29.1 (SD: 9.6) years, and body mass index was 32.2 (SD: 8.1) kg/m². Nine patients had diabetes, and 22 had prediabetes. SPL was used in combination with combined oral contraceptive pills in 55 participants and progestin-only pills/long-acting reversible contraception in 28; metformin was added in 35, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers in 15. Median SPL dose was 100 (range: 50-150) mg. A total of 327 serum potassium measurements were obtained (84 pre-exposure and 243 postexposure). Four potassium measurements were above the reference range before exposure and 19 during exposure. All potassium measurements above the reference range during follow-up were classified as mild hyperkalemia (5.1-5.5 mEq/L). CONCLUSIONS: The present findings suggest that women with PCOS, without kidney or heart disease, using SPL combined with hormonal contraception for managing clinical hyperandrogenism have a low incidence of hyperkalemia and well-tolerated minor adverse effects.

RESUMO

OBJECTIVE: Hyperandrogenic skin disorders, such as hirsutism, acne and alopecia, affect approximately 10-20% of women of reproductive age, reducing quality of life and causing psychological impairment. Spironolactone is a commonly used antiandrogen, especially in women who are not sexually active or have contraindications to hormonal contraceptives. The aim of this study was to evaluate the effects of spironolactone, especially after its withdrawal, in patients with hyperandrogenic skin disorders. METHODS: Retrospective analysis of 63 women with hyperandrogenic skin symptoms due to polycystic ovary syndrome (PCOS), treated with spironolactone for at least 6 months as first-line treatment. RESULTS: After a mean time of treatment of 25.7 months, all patients reported a significant improvement in hyperandrogenic skin disorders; only 5 patients were dissatisfied and required the addition of an oral contraceptive. The therapy was well tolerated and the most frequent side-effect was intermestrual bleeding in 68.2% of cases, affecting mainly classic PCOS phenotype. Thirthyeight patients showed prolonged effects 33.7 months after spironolactone withdrawal, whereas 20 relapsed 17.5 months after discontinuation. No significant difference in clinical and biochemical parameters was observed between these two groups both at baseline and after spironolactone treatment. Ovulatory PCOS patients were treated for a shorter time and reported earlier relapse than classic PCOS patients. CONCLUSION: Spironolactone is an effective and safe treatment for hyperandrogenic skin disorders, showing long-lasting effects even several months after its discontinuation.

RESUMO

BACKGROUND & AIMS: Finerenone is a novel non-steroidal mineralocorticoid antagonist (MRA) recently approved for the treatment of chronic kidney disease (CKD) in people with type 2 diabetes (T2D). We aim to conduct a systematic review of finerenone to know the efficacy and safety of finerenone in CKD with or without T2D. METHODS: A systematic search in the electronic database of PubMed and Google Scholar was made from inception until September 09, 2022, using several MeSH keywords related to finerenone. Ongoing trials were additionally searched from ClinicalTrials.Gov. RESULTS: Five phase 2 and three phase 3, randomized, double-blind, placebo- or active-controlled studies of finerenone have been published to date and several other randomized and real-world studies of finerenone are currently undergoing. CONCLUSIONS: In short-term studies in patients with CKD and reduced ejection heart failure, with or without T2D, finerenone 20 mg appears to have a better renal outcome compared with spironolactone and a better mortality outcome compared with eplerenone, with significantly lesser hyperkalemia compared to both spironolactone and finerenone. In long-term studies in patients with CKD and T2D, finerenone 10/20 mg significantly reduces the progression of renal disease and reduced CV endpoints (especially heart failure hospitalization) compared to placebo. Finerenone has no effect on HbA1c, body weight, and sexual side effects including gynecomastia, and has only a modest effect on blood pressure. However, hyperkalemia leading to drug withdrawal was significantly higher with finerenone compared to placebo. Safety data in real-world settings is a pressing priority.

RESUMO

BACKGROUND OF STUDY: Globally, many reproductive aged women are affected by polycystic ovarian syndrome (PCOS), which is a common endocrine and metabolic disorder that is linked with adipose dysfunction and chronic low-grade inflammation. Spironolactone (SPL), a mineralocorticoid receptor blocker has been documented as a metabolic modulator. However, its immunomodulatory effect in PCOS is unknown. Therefore, the present study hypothesized that SPL would ameliorate adipose dysfunction and inflammation in experimental PCOS animals. MATERIALS AND METHODS: Female Wistar rats that were 8 weeks old were allocated into three groups. Group 1 received vehicle (distilled water; p.o.), group 2 received letrozole (1 mg/kg; p.o.) and group 3 received letrozole plus SPL (0.25 mg/kg, p.o.). The administration was performed once daily for 21 days. RESULTS: The experimental PCOS animals showed insulin resistance, hyperinsulinemia and hyperandrogenism as well as oxidative stress and elevated inflammatory biomarkers (NF-kB/TNF-/IL-6) as well as a significant decrease in triglycerides, total cholesterol, free fatty acids, GSH and G6PD in the adipose tissue of PCOS animals. In addition, immunohistochemical assessment of adipose tissue showed significant expression of BAX and inflammasome, indicating apoptosis and inflammation compared to control animals. Nevertheless, administration of SPL attenuated these perturbations. CONCLUSION: Altogether, the present study suggests that low-dose spironolactone confers protection against adipose dysfunction in experimental PCOS animals by attenuating inflammation, oxidative stress and cellular apoptosis.

RESUMO

IMPORTANCE: While originally approved for the management of heart failure, hypertension, and edema, spironolactone is commonly used off label in the management of acne, hidradenitis, androgenetic alopecia, and hirsutism. However, spironolactone carries an official warning from the US Food and Drug Administration regarding potential for tumorigenicity. OBJECTIVE: To determine the pooled occurrence of cancers, in particular breast and prostate cancers, among those who were ever treated with spironolactone. DATA SOURCES: PubMed, Cochrane Library, Embase, and Web of Science were searched from inception through June 11, 2021. The search was restricted to studies in the English language. STUDY SELECTION: Included studies reported the occurrence of cancers in men and women 18 years and older who were exposed to spironolactone. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers (K.B. and H.H.) selected studies, extracted data, and appraised the risk of bias using the Newcastle-Ottawa Scale. Studies were synthesized using random effects meta-analysis. MAIN OUTCOMES AND MEASURES: Cancer occurrence, with a focus on breast and prostate cancers. RESULTS: Seven studies met eligibility criteria, with sample sizes ranging from 18 035 to 2.3 million and a total population of 4 528 332 individuals (mean age, 62.6-72.0 years; in the studies without stratification by sex, women accounted for 17.2%-54.4%). All studies were considered to be of low risk of bias. No statistically significant association was observed between spironolactone use and risk of breast cancer (risk ratio [RR], 1.04; 95% CI, 0.86-1.22; certainty of evidence very low). There was an association between spironolactone use and decreased risk of prostate cancer (RR, 0.79; 95% CI, 0.68-0.90; certainty of evidence very low). There was no statistically significant association between spironolactone use and risk of ovarian cancer (RR, 1.52; 95% CI, 0.84-2.20; certainty of evidence very low), bladder cancer (RR, 0.89; 95% CI, 0.71-1.07; certainty of evidence very low), kidney cancer (RR, 0.96; 95% CI, 0.85-1.07; certainty of evidence low), gastric cancer (RR, 1.02; 95% CI, 0.80-1.24; certainty of evidence low), or esophageal cancer (RR, 1.09; 95% CI, 0.91-1.27; certainty of evidence low). CONCLUSIONS AND RELEVANCE: In this systematic review and meta-analysis, spironolactone use was not associated with a substantial increased risk of cancer and was associated with a decreased risk of prostate cancer. However, the certainty of the evidence was low and future studies are needed, including among diverse populations such as younger individuals and those with acne or hirsutism.

RESUMO

ABSTRACT: We explored the protective effect of spironolactone on cardiac function in the patients undergoing coronary artery bypass grafting (CABG) by determining serum hypoxia-inducible factor-1α (HIF-1α) before and after CABG. We used the propensity score matching method retrospectively to select 174 patients undergoing CABG in our hospital from March 2018 to December 2019. Of the 174 patients, 87 patients taking spironolactone for more than 3 months before CABG were used as a test group and other 87 patients who were not taking spironolactone as a control group. In all patients, serum HIF-1α and troponin I levels were determined before as well as 24 hours and 7 days after CABG, serum N-terminal probrain natriuretic peptide (NT-proBNP) level was determined before as well as 12, 24, and 36 hours after CABG, and electrocardiographic monitoring was performed within 36 hours after CABG. The results indicated that there were no significant differences in the HIF-1α level between the test group and the control group before and 7 days after CABG, but the HIF-1α level was significantly lower in the test group than that in the control group 24 hours after CABG (P < 0.01). The 2 groups were not significantly different in the troponin I level at any time point. There was no significant difference in the serum NT-proBNP level between the test group and the control group before CABG, but NT-proBNP (BNP) levels were all significantly lower in the test group than those in the control group at postoperative 12, 24, and 36 hour time points (all P <0.05). The incidence of postoperative atrial fibrillation was also significantly lower in the test group than that in the control group (P = 0.035). Spironolactone protects cardiac function probably by improving myocardial hypoxia and inhibiting myocardial remodeling.

RESUMO

BACKGROUND: People with chronic kidney disease (CKD) requiring dialysis are at a particularly high risk of cardiovascular death and morbidity. Several clinical studies suggested that aldosterone antagonists would be a promising treatment option for people undergoing dialysis. However, the clinical efficacy and potential harm of aldosterone antagonists for people with CKD on dialysis has yet to be determined. OBJECTIVES: This review aimed to evaluate the benefits and harms of aldosterone antagonists, both non-selective (spironolactone) and selective (eplerenone), in comparison to control (placebo or standard care) in people with CKD requiring haemodialysis (HD) or peritoneal dialysis (PD). SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies up to 5 August 2020 using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA: We included parallel randomised controlled trials (RCTs), cross-over RCTs, and quasi-RCTs (where group allocation is by a method that is not truly random, such as alternation, assignment based on alternate medical records, date of birth, case record number, or other predictable methods) that compared aldosterone antagonists with placebo or standard care in people with CKD requiring dialysis. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed risk of bias for included studies. We used a random-effects model meta-analysis to perform a quantitative synthesis of the data. We used the I² statistic to measure heterogeneity among the studies in each analysis. We indicated summary estimates as a risk ratio (RR) for dichotomous outcomes, mean difference (MD) for continuous outcomes, or standardised mean differences (SMD) if different scales were used, with their 95% confidence interval (CI). We assessed the certainty of the evidence for each of the main outcomes using the GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) approach. MAIN RESULTS: We included 16 studies (14 parallel RCTs and two cross-over RCTs) involving a total of 1446 participants. Thirteen studies compared spironolactone to placebo or standard care and one study compared eplerenone to a placebo. Most included studies had an unclear or high risk of bias. Compared to control, aldosterone antagonists probably reduced the risk of death (any cause) for people with CKD requiring dialysis (9 studies, 1119 participants: RR 0.45, 95% CI 0.30 to 0.67; I² = 0%; moderate certainty of evidence). Aldosterone antagonist probably decreased the risk of death due to cardiovascular disease (6 studies, 908 participants: RR 0.37, 95% CI 0.22 to 0.64; I² = 0%; moderate certainty of evidence) and cardiovascular and cerebrovascular morbidity (3 studies, 328 participants: RR 0.38, 95% CI 0.18 to 0.76; I² = 0%; moderate certainty of evidence). While aldosterone antagonists probably increased risk of gynaecomastia compared with control (4 studies, 768 participants: RR 5.95, 95% CI 1.93 to 18.3; I² = 0%; moderate certainty of evidence), aldosterone antagonists may make little or no difference to the risk of hyperkalaemia (9 studies, 981 participants: RR 1.41, 95% CI 0.72 to 2.78; I² = 47%; low certainty of evidence). Aldosterone antagonists had a marginal effect on left ventricular mass among participants undergoing dialysis (8 studies, 633 participants: SMD -0.42, 95% CI -0.78 to 0.05; I² = 77%). In people with CKD requiring dialysis received aldosterone antagonists compared to control, there were 72 fewer deaths from all causes per 1000 participants (95% CI 47 to 98) with a number needed to treat for an additional beneficial outcome (NNTB) of 14 (95% CI 10 to 21) and for gynaecomastia were 26 events per 1000 participants (95% CI 15 to 39) with a number need to treat for an additional harmful outcome (NNTH) of 38 (95% CI 26 to 68). AUTHORS' CONCLUSIONS: Based on moderate certainty of the evidence, aldosterone antagonists probably reduces the risk of all-cause and cardiovascular death and probably reduces morbidity due to cardiovascular and cerebrovascular disease in people with CKD requiring dialysis. For the adverse effect of gynaecomastia, the risk was increased compared to control. For this outcome, the absolute risk was lower than the absolute risk of death. It is hoped the three large ongoing studies will provide better certainty of evidence.

RESUMO

BACKGROUND: Spironolactone reduces morbidity and mortality in patients with heart failure (HF) with reduced ejection fraction (EF) and decreases hospitalizations in HF with preserved EF. To minimize the risk of hyperkalemia, patients must have an estimated glomerular filtration rate (eGFR) > 30 mL/min/1.73 m2 and potassium < 5.0 mEq/L prior to initiation; however, spironolactone is prescribed outside these parameters. The objective of this study was to evaluate the safety and tolerability of spironolactone in patients with HF and chronic kidney disease (CKD). METHODS: This single-center, retrospective cohort study evaluated patients ≥ 18 years with HF and CKD stages 3-5 who received ≥ 48 h of spironolactone therapy and were hospitalized from February 2018 to August 2019. The primary outcome was incidence of hyperkalemia (potassium ≥ 5.5 mEq/L). RESULTS: Overall, 121 patients were evaluated: 52.1% (n = 63) had an EF > 40% and 47.9% (n = 58) had an EF ≤ 40% with 69.4% (n = 84) CKD stage 3, 24.8% (n = 30) stage 4, and 5.8% (n = 7) stage 5. Spironolactone was initiated prior to admission (PTA) for 54.5% (n = 66) of patients, while 45.5% (n = 55) of orders were initiated during hospitalization. Eight patients (6.6%) experienced inpatient hyperkalemia-all with PTA spironolactone. Patients who experienced inpatient hyperkalemia had a numerically lower eGFR that was not statistically significant (35.40 vs. 38.22 mL/min/1.73 m2; p = 0.730). Patients with CKD stage 3 (n = 4) had numerically higher rates of inpatient hyperkalemia than stages 4 (n = 1) or 5 (n = 3) (50%, 12.5%, and 37.5% respectively; p < 0.05). CONCLUSION: Spironolactone may be safe to initiate in hospitalized patients with HF and CKD; however, appropriateness of therapy must be assessed upon admission to the hospital. Larger studies are needed for conclusive results.

RESUMO

AIMS: Aldosterone has been found to influence cancer cell growth, cell cycle regulation and cell migration, including in prostate cancer cells. Spironolactone is an aldosterone antagonist used for managing chronic heart failure (HF) with known antiandrogenic effects. We examined the effect of spironolactone exposure amongst men with HF on the incidence of prostate cancer. METHODS: This retrospective cohort study utilized provincial clinical and administrative databases from the Manitoba Centre for Health Policy. Incident cases of prostate cancer were identified from the provincial cancer registry, and spironolactone exposure was quantified from pharmacare databases. A multivariable proportional hazards model was used to assess the time-dependent impact of spironolactone exposure on prostate cancer incidence. RESULTS: A total of 18 562 men with newly diagnosed HF from 2007 to 2015 with a median age of 72 years (interquartile range: 61-81) and a median follow-up from HF diagnosis to prostate cancer incidence of 2.7 years (interquartile range: 1.1-4.9) were included. A time-dependent multivariable analysis of spironolactone exposure following HF diagnosis found a reduced the risk of prostate cancer hazard ratio 0.55 (95% confidence interval 0.31-0.98, P = .043). CONCLUSION: Spironolactone exposure significantly reduced the incidence of prostate cancer amongst men with HF. These findings support the plausibility of aldosterone as a promoter of prostate cancer growth and development. Prospective clinical trials are warranted to further assess the role of spironolactone or other mineralocorticoid receptor antagonists as a means to prevent prostate cancer development or as an adjunctive measure to prostate cancer treatments.

RESUMO

Acne vulgaris (AV) is the most common skin condition affecting adolescents, most likely due to elevated androgen levels during puberty. Androgens stimulate and enlarge the sebaceous glands and keratinocytes, resulting in increased production of sebum and abnormal hyperproliferation of keratinocytes which lead to the formation of acne lesions. Current standard of care for AV includes topical therapies for mild cases and antibiotics or oral retinoids for severe cases. In recent years, spironolactone, an aldosterone antagonist and diuretic, has been applied to the treatment of AV due to its anti-androgen effects. Spironolactone is currently recommended in women who use oral contraceptives, are refractory to or contraindicated for standard treatment, show clinical signs of hyperandrogenism, or present with late-onset or persistent-recurrent AV past the teenage years. It is not prescribed to adolescents due to potential side effects; however, current data studying adults indicate that most side effects are mild, and that potential associations with hyperkalemia and increased risk of cancer are not sufficiently supported. Hence, we believe that spironolactone may be a safe and effective therapy for adolescent AV.

RESUMO

BACKGROUND: Data on the effects of excess aldosterone on glucose metabolism are inconsistent. This study compared the changes in glucose metabolism in patients with primary aldosteronism (PA) after adrenalectomy or treatment with a mineralocorticoid receptor antagonist (MRA). METHODS: Overall, 241 patients were enrolled; 153 underwent adrenalectomy and 88 received an MRA. Fasting glucose, homeostatic model assessment of insulin resistance (HOMA-IR), and homeostatic model assessment of ß-cell function (HOMA-ß) were compared between the treatment groups after 1 year. Plasma aldosterone concentration (PAC) and factors determining HOMA-IR and PAC were evaluated. RESULTS: No baseline differences were observed between the groups. Fasting insulin, HOMA-IR, and HOMA-ß increased in both groups and there were no significant differences in fasting glucose following treatment. Multiple regression analysis showed associations between PAC and HOMA-IR (ß=0.172, P=0.017) after treatment. Treatment with spironolactone was the only risk factor associated with PAC >30 ng/dL (odds ratio, 5.2; 95% confidence interval [CI], 2.7 to 10; P<0.001) and conferred a 2.48-fold risk of insulin resistance after 1 year compared with surgery (95% CI, 1.3 to 4.8; P=0.007). CONCLUSION: Spironolactone treatment might increase insulin resistance in patients with PA. This strengthened the current recommendation that adrenalectomy is the preferred strategy for patient with positive lateralization test. Achieving a post-treatment PAC of <30 ng/dL for improved insulin sensitivity may be appropriate.

RESUMO

BACKGROUND: Treatment with angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB) is used to reduce proteinuria and retard the progression of chronic kidney disease (CKD). However, resolution of proteinuria may be incomplete with these therapies and the addition of an aldosterone antagonist may be added to further prevent progression of CKD. This is an update of a Cochrane review first published in 2009 and updated in 2014. OBJECTIVES: To evaluate the effects of aldosterone antagonists (selective (eplerenone), non-selective (spironolactone or canrenone), or non-steroidal mineralocorticoid antagonists (finerenone)) in adults who have CKD with proteinuria (nephrotic and non-nephrotic range) on: patient-centred endpoints including kidney failure (previously know as end-stage kidney disease (ESKD)), major cardiovascular events, and death (any cause); kidney function (proteinuria, estimated glomerular filtration rate (eGFR), and doubling of serum creatinine); blood pressure; and adverse events (including hyperkalaemia, acute kidney injury, and gynaecomastia). SEARCH METHODS: We searched the Cochrane Kidney and Transplant Register of Studies up to 13 January 2020 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs that compared aldosterone antagonists in combination with ACEi or ARB (or both) to other anti-hypertensive strategies or placebo in participants with proteinuric CKD. DATA COLLECTION AND ANALYSIS: Two authors independently assessed study quality and extracted data. Data were summarised using random effects meta-analysis. We expressed summary treatment estimates as a risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, or standardised mean difference (SMD) when different scales were used together with their 95% confidence interval (CI). Risk of bias were assessed using the Cochrane tool. Evidence certainty was evaluated using GRADE. MAIN RESULTS: Forty-four studies (5745 participants) were included. Risk of bias in the evaluated methodological domains were unclear or high risk in most studies. Adequate random sequence generation was present in 12 studies, allocation concealment in five studies, blinding of participant and investigators in 18 studies, blinding of outcome assessment in 15 studies, and complete outcome reporting in 24 studies. All studies comparing aldosterone antagonists to placebo or standard care were used in addition to an ACEi or ARB (or both). None of the studies were powered to detect differences in patient-level outcomes including kidney failure, major cardiovascular events or death. Aldosterone antagonists had uncertain effects on kidney failure (2 studies, 84 participants: RR 3.00, 95% CI 0.33 to 27.65, I² = 0%; very low certainty evidence), death (3 studies, 421 participants: RR 0.58, 95% CI 0.10 to 3.50, I² = 0%; low certainty evidence), and cardiovascular events (3 studies, 1067 participants: RR 0.95, 95% CI 0.26 to 3.56; I² = 42%; low certainty evidence) compared to placebo or standard care. Aldosterone antagonists may reduce protein excretion (14 studies, 1193 participants: SMD -0.51, 95% CI -0.82 to -0.20, I² = 82%; very low certainty evidence), eGFR (13 studies, 1165 participants, MD -3.00 mL/min/1.73 m², 95% CI -5.51 to -0.49, I² = 0%, low certainty evidence) and systolic blood pressure (14 studies, 911 participants: MD -4.98 mmHg, 95% CI -8.22 to -1.75, I² = 87%; very low certainty evidence) compared to placebo or standard care. Aldosterone antagonists probably increase the risk of hyperkalaemia (17 studies, 3001 participants: RR 2.17, 95% CI 1.47 to 3.22, I² = 0%; moderate certainty evidence), acute kidney injury (5 studies, 1446 participants: RR 2.04, 95% CI 1.05 to 3.97, I² = 0%; moderate certainty evidence), and gynaecomastia (4 studies, 281 participants: RR 5.14, 95% CI 1.14 to 23.23, I² = 0%; moderate certainty evidence) compared to placebo or standard care. Non-selective aldosterone antagonists plus ACEi or ARB had uncertain effects on protein excretion (2 studies, 139 participants: SMD -1.59, 95% CI -3.80 to 0.62, I² = 93%; very low certainty evidence) but may increase serum potassium (2 studies, 121 participants: MD 0.31 mEq/L, 95% CI 0.17 to 0.45, I² = 0%; low certainty evidence) compared to diuretics plus ACEi or ARB. Selective aldosterone antagonists may increase the risk of hyperkalaemia (2 studies, 500 participants: RR 1.62, 95% CI 0.66 to 3.95, I² = 0%; low certainty evidence) compared ACEi or ARB (or both). There were insufficient studies to perform meta-analyses for the comparison between non-selective aldosterone antagonists and calcium channel blockers, selective aldosterone antagonists plus ACEi or ARB (or both) and nitrate plus ACEi or ARB (or both), and non-steroidal mineralocorticoid antagonists and selective aldosterone antagonists. AUTHORS' CONCLUSIONS: The effects of aldosterone antagonists when added to ACEi or ARB (or both) on the risks of death, major cardiovascular events, and kidney failure in people with proteinuric CKD are uncertain. Aldosterone antagonists may reduce proteinuria, eGFR, and systolic blood pressure in adults who have mild to moderate CKD but may increase the risk of hyperkalaemia, acute kidney injury and gynaecomastia when added to ACEi and/or ARB.

RESUMO

INTRODUCTION: The present study was conducted to compare the efficacy and side effects of Spironolactone and Eplerenone in management of ascites due to liver cirrhosis. MATERIALS AND METHODS: 105 patients of ascites with liver cirrhosis were randomized into three groups of 35 patients each. Group I was given Spironolactone 100 mg, group II was given Eplerenone 100 mg and group III was given Eplerenone 50 mg. All patients were put on salt-restricted diet (less than or equal to 2 g of sodium) and no loop diuretics were used. Patients were followed after 7 days from the baseline and then biweekly for the period of three months and serial measurements of weight, abdominal girth and incidence of side effects especially gynecomastia, mastalgia, hyperkalemia were recorded. Results were compared. Patients having Child-Turcotte-Pugh score-C, massive ascites, hepatic encephalopathy, Hepatorenal syndrome and ascites due to cardiac, renal, malignant causes were excluded. OBSERVATIONS: Difference in mean weight reduction was non significant (P = 0.964) in group I and group II whereas the difference was significant when comparison was made between Group I and III; and Group II and III (P = <0.001, <0.001, respectively). In group I, the incidence of gynecomastia was 14.28% whereas in group II and group III no case of gynecomastia was observed (P <0.001, <0.001). Hyperkalemia was present in one patient (2.8%) in group I whereas no patient developed hyperkalemia in group II and group III (P = >0.05, >0.05). CONCLUSION: Eplerenone and spironolactone are equally effective in management of ascites due to liver cirrhosis but side effect profile of eplerenone scores over Spironolactone.

RESUMO

OBJECTIVES: The authors examined efficacy and safety of spironolactone by age in the Americas region (N = 1,767) of the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) trial. BACKGROUND: Heart failure with preserved ejection fraction disproportionately affects older adults who may exhibit changes in physiology and variable pharmacokinetics. METHODS: TOPCAT enrolled patients with heart failure and a left ventricular ejection fraction ≥45% who were age 50 or older with an estimated glomerular filtration rate ≥30 mL/min/1.73 m2 and prior heart failure hospitalization or elevated natriuretic peptide levels. Participants were randomized to spironolactone or placebo with a mean follow-up duration of 3.3 years. We assessed treatment effect and safety by protocol-defined age categories (<65, 65 to 74, and ≥75 years). RESULTS: The mean age was 72 ± 10 years (range 50 to 97 years) with 41% over the age of 75 years. Participants ≥75 years were more commonly women and white and had a lower body mass index and estimated glomerular filtration rate compared with the younger age categories. Spironolactone reduced the primary composite outcome compared with placebo across all age categories (p interaction = 0.42). However, spironolactone was associated with an increased risk of the safety endpoint (hazard ratio: 2.54; 95% confidence interval: 1.91 to 3.37; p < 0.001), particularly in older age groups (p interaction = 0.02). Findings in the whole TOPCAT cohort were consistent with results from the Americas region. CONCLUSIONS: In this post hoc, exploratory analysis of the TOPCAT trial data from the Americas region, although there was no effect of age on efficacy, there were considerable effects of age on increased rates of adverse safety outcomes. These results should be weighed when considering spironolactone for older heart failure with preserved ejection fraction patients.

RESUMO

The impact of antihypertensive drugs on blood pressure does not differ according to the sex. There are women-specific conditions or medical conditions encountered more frequently among womens that guide the selection of therapy such as a desire to become pregnant, a pregnancy, a polycystic ovarian syndrome, breast cancer, osteoporosis or migraine.

RESUMO

Background Duchenne muscular dystrophy incurs nearly universal dilated cardiomyopathy by the third decade of life, preceded by myocardial damage and impaired left ventricular strain by cardiac magnetic resonance. It has been shown that (1) mineralocorticoid receptor antagonist therapy with spironolactone attenuated damage while maintaining function when given early in a mouse model and (2) low-dose eplerenone stabilized left ventricular strain in boys with Duchenne muscular dystrophy and evident myocardial damage but preserved ejection fraction. We hypothesized that moderate-dose spironolactone versus eplerenone would provide similar cardioprotection in this first head-to-head randomized trial of available mineralocorticoid receptor antagonists, the AIDMD (Aldosterone Inhibition in Duchenne Muscular Dystrophy) trial. Methods and Results This was a multicenter, double-blind, randomized, noninferiority trial. Subjects were randomized to eplerenone, 50 mg, or spironolactone, 50 mg, orally once daily for 12 months. The primary outcome was change in left ventricular systolic strain at 12 months. Among 52 enrolled male subjects, aged 14 (interquartile range, 12-18) years, spironolactone was noninferior to eplerenone (∆strain, 0.4 [interquartile range, -0.4 to 0.6] versus 0.2 [interquartile range, -0.2 to 0.7]; P=0.542). Renal and pulmonary function remained stable in both groups, and no subjects experienced serious hyperkalemia. Infrequent adverse events included gynecomastia in one subject in the spironolactone arm and facial rash in one subject in the eplerenone arm. Conclusions In boys with Duchenne muscular dystrophy and preserved left ventricular ejection fraction, spironolactone added to background therapy is noninferior to eplerenone in preserving contractile function. These findings support early mineralocorticoid receptor antagonist therapy as effective and safe in a genetic disease with high cardiomyopathy risk.

RESUMO

BACKGROUND: Although spironolactone is an effective treatment for androgen-mediated cutaneous disorders, the potential sexual side-effects are poorly documented in current literature. AIM: The purpose of this study was to provide clinical evidence that spironolactone may be a cause of hormonally associated vestibulodynia and female sexual arousal disorder. METHODS: A database search of a vulvar disorders clinic revealed 7 cases in which spironolactone may have caused or contributed to dyspareunia and decreased arousal. In all cases, the patients stopped taking spironolactone and used a compounded estradiol 0.01%/testosterone 0.1% gel to the vestibule twice daily. 2 cases are discussed to further illustrate these previously unreported side effects. OUTCOMES: Improvement in sexual function was determined after treatment. RESULTS: Examination of women taking spironolactone who presented with the complaints of introital dyspareunia revealed vulvar vestibular atrophy and tenderness, especially at the glandular ostia. After stopping spironolactone and applying a topical estrogen/testosterone gel to the vestibule, all women had significant improvement in their vulvar atrophy, resolution of their dyspareunia, and improved sexual arousal. CLINICAL IMPLICATIONS: Use of spironolactone may be a cause of hormonally associated vestibulodynia and female sexual arousal disorder. STRENGTHS AND LIMITATIONS: The influence of spironolactone on vulvar health and sexual function is poorly documented in the medical literature. The strength of this paper is that it examines the potential deleterious side effects of this medication on female sexual function. However, the most significant limitation of this case series is that it was not a prospective, controlled study. CONCLUSIONS: Although treatment of androgen-mediated cutaneous disorders is warranted, medical providers should be aware of the potential sexual side effects of this anti-androgenic medication.

RESUMO

Mineralocorticoid receptor antagonism prevents acute kidney injury induced by ischemia-reperfusion in rodent and pig preclinical models. In a pilot study, we showed that spironolactone (25 mg) reduced oxidative stress after 5 days of kidney transplant (KT). In the present study, we investigated the effects of higher doses (50 and 100 mg) of spironolactone on kidney function, tubular injury markers, and oxidative stress in living donor KT recipients. We included KT recipients aged 18 yr or older who received immunosuppression therapy with IL-2 receptor antagonist, mycophenolate mofetil, corticosteroids, and tacrolimus with negative cross-match, and compatible blood group. Patients were randomized to receive placebo (n = 27), spironolactone (50 mg, n = 25), or spironolactone (100 mg, n = 25). Treatment was given from 3 days before and up to 5 days after KT. Serum creatinine, K+, urine neutrophil gelatinase-associated lipocalin-2, heat shock protein 72, and 8-hydroxy-2-deoxyguanosine levels were assessed. As expected, kidney function was improved after KT. Serum K+ remained in the normal range along the study. There was no significant effect of spironolactone on urinary neutrophil gelatinase-associated lipocalin-2 levels, whereas the increase in urinary heat shock protein 72 levels tended to be less intense in the 100 mg spironolactone-treated group (P = 0.054). In the placebo-treated group, urinary 8-hydroxylated-guanosine levels increased on days 3 and 5 after transplantation. This effect was prevented in patients that received spironolactone. In conclusion, spironolactone reduces the acute increase in urinary oxidative stress in living donor KT recipients.
