Abstract
BACKGROUND Hyperkalemia is associated with kidney function decline in patients with non-dialysis dependent chronic kidney disease, but this relationship is unclear for residual kidney function among hemodialysis (HD) patients. METHODS We conducted a retrospective cohort study of 6655 patients who started HD from January 2007 to December 2011 and who had data on renal urea clearance (KRU). Serum potassium levels were stratified into four groups (i.e. ≤4.0, >4.0 to ≤ 4.5, >4.5 to ≤ 5.0, >5.0 mEq/L) and 1-year KRU slope for each group was estimated by a linear mixed-effects model. RESULTS Higher serum potassium was associated with greater decline in KRU, and the greatest decrease in KRU (-0.20, 95% CI -0.50, -0.06) was observed for baseline potassium > 5.0 mEq/L in the fully adjusted model. Mediation analysis showed that KRU slope mediated 1.78% of the association between serum potassium and mortality. CONCLUSIONS In conclusion, hyperkalemia is associated with decline in residual kidney function amongst incident HD patients. These findings may have important clinical implications in the management of hyperkalemia in advanced CKD if confirmed in additional studies including clinical trials.

Efficacy and safety of dual vs single renin-angiotensin-aldosterone system blockade in chronic kidney disease: An updated meta-analysis of randomized controlled trials. Medicine (Baltimore) 2021; 100:e26544. [PMID: 34477114 PMCID: PMC8415955 DOI: 10.1097/md.0000000000026544] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 06/14/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND To lower albuminuria and to achieve blood pressure (BP) goals, dual renin-angiotensin-aldosterone system (RAAS) inhibitors are sometimes used in clinical practice for the treatment of CKD. However, the efficacy and safety of dual RAAS blockade therapy remains controversial. METHODS PubMed, EMBASE, and Cochrane Library were searched, and random effects model was used to calculate the effect sizes of eligible studies. Potential sources of heterogeneity were detected by meta-regression and subgroup analysis. RESULTS The present meta-analysis of 72 randomized controlled trials with 10,296 patients demonstrated that dual RAAS blockade therapy was superior to monotherapy in reducing the urine albumin excretion, urine protein excretion, and BP. These beneficial effects were related to the decrease of glomerular filtration rate, the increase of serum potassium level, and higher rates of hyperkalemia and hypotension. Meanwhile, these effects did not lead to improvements in short-term or long-term outcomes, including doubling of serum creatinine, acute kidney injury, end-stage renal disease, mortality, and hospitalization. Compared with the single therapy, angiotensin-converting enzyme inhibitor (ACEI) in combination with angiotensin-receptor blocker (ARB) was a better dual therapy than ACEI or ARB in combination with renin inhibitor or aldosterone receptor antagonist in decreasing urine albumin excretion, urine protein excretion and BP, and the combination was not associated with a lower glomerular filtration rate. CONCLUSION Compared with the single therapy, ACEI in combination with ARB was a better dual therapy than ACEI or ARB in combination with renin inhibitor or aldosterone receptor antagonist. Although ACEI in combination with ARB was associated with higher incidences of hyperkalemia and hypotension, careful individualized management and potassium binders may further expand its application (PROSPERO number CRD42020179398).

Vitamin D deficiency in chronic kidney disease: Myth or reality? Clin Chim Acta 2021; 523:35-37. [PMID: 34480954 DOI: 10.1016/j.cca.2021.08.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 08/28/2021] [Accepted: 08/30/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND AND OBJECTIVE Chronic kidney disease (CKD) is a public health problem, which has a prevalence of 17.2% in India. As kidney function decreases, there is a gradual deterioration in the regulation of bone mineral homeostasis. Vitamin D is recognized as the central player in the maintenance of bone health in CKD. Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines suggest that vitamin D supplementation should be given to all CKD patients with serum 25-hydroxy vitaminD (25(OH)D) level < 30 ng/mL. Hence we undertook this study to evaluate the vitamin D status in South Indian patients with CKD. METHODS Fifty-nine non-dialysis CKD patients of stage 3 and 4 were recruited and screened for 25(OH)D deficiency. Circulating levels of 25(OH)D were measured using chemiluminescence immunoassay. The estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology (CKD-EPI) equation. Serum calcium, phosphorous, creatinine and alkaline phosphatase levels were measured spectrophotometrically by an autoanalyzer. RESULTS Contrary to published literature, 75% of South Indian CKD patients had normal 25(OH)D (≥30 ng/mL), 15% of them had insufficient (20-29 ng/mL) and 10% had 25(OH)D deficiency (<20 ng/mL). Alkaline phosphatase levels were found to be increased in only 20% of cases. Calcium1 levels were normal in all CKD cases and hyperphosphatemia was observed in 5% of CKD patients. CONCLUSION We found that most of our CKD patients (75%) had normal vitamin D levels. This paradoxical finding could be explained by the fact that most of them gave a history of intake of vitamin D and calcium supplements, as advised by their doctors before coming to our institute. Hence we conclude that before prescribing vitamin D or calcium supplements to CKD patients, their 25(OH)D status should be ascertained to prevent hypervitaminosis D and its complications.

Abstract
INTRODUCTION Aldosterone synthase (AS) is a key enzyme involved in the final three rate-limiting steps of the biosynthesis pathway of aldosterone, and its inhibition has been considered as an effective strategy to treat hypertension, heart failure, and related cardio-metabolic diseases. AREA COVERED This review provides an update on the discovery and development of aldosterone synthase inhibitors by means of patents published between January 2014 and March 2021. The molecules are classified by pharmaceutical company with progress that has been made in clinical trials being highlighted. EXPERT OPINION Mineralocorticoid receptor antagonists (MRAs) and aldosterone synthase inhibitors (ASI) represent two of the main approaches for the blockade of aldosterone. Clinical success, as well as foreseen side effects of steroidal MRAs, prompted the discovery and development of ASI. Since the observation of decreased cortisol levels in clinical trials for LCI699, subsequent efforts have been largely focused on improving its selectivity over hCYP11B1. Candidates with improved potency and selectivity are under investigation across a wide range of indications. Whether ASI will provide an additional therapeutic advantage over current safe and selective non-steroidal MRAs is highly anticipated.

Abstract
Apararenone is a long-acting, nonsteroidal mineralocorticoid receptor antagonist (MRA). The safety, tolerability, and pharmacokinetic (PK) and pharmacodynamic (PD) profiles of single- and multiple-dose apararenone were assessed in 3 phase 1 randomized, double-blind studies in 223 healthy adults. Study 1 assessed the PK, safety/tolerability, and PD of single-dose apararenone (3.75-640 mg) and multiple-dose apararenone (10-40 mg/day on days 1-14, 320 mg loading dose on day 1 + 10 mg/day on days 2-14, or 40-320 mg loading dose on day 1 + 2.5-20 mg/day on days 2-14) in Caucasian and Black men and women. Study 2 assessed the PK and safety of single-dose apararenone (5-320 mg) in healthy Japanese men. Study 3 assessed the PK, PD, and safety/tolerability of single-dose apararenone (160 or 640 mg) or eplerenone (200 mg; only for 160 mg of apararenone), each after fludrocortisone challenge in Caucasian men. In studies 1 and 2, an approximately dose-proportional increase was observed in PK parameters over the apararenone dose range of 3.75-40 mg; at higher doses, a less than dose-proportional increase was observed. Food, sex, age, and race had no apparent effect on apararenone PK. A long half-life was seen for apararenone and its principal metabolite; in addition, the exposure of the metabolite was lower than that of apararenone. Apararenone suppressed the decrease in urinary sodium and potassium ion ratio that occurs after loading with fludrocortisone. These studies support the mechanism of action of apararenone as an MRA, and further clinical development is warranted.

Abstract
The progression of chronic kidney disease (CKD) cannot be completely inhibited. We first explored factors contributing to CKD progression in patients with CKD in a prospective observational study. In the next phase, we focused on the effects of aldosterone, conducting a single-blinded placebo-controlled study using the selective mineralocorticoid receptor antagonist (MRA), eplerenone (25 mg/day). We recruited patients with CKD stage 2 and 3 whose plasma aldosterone concentration was above 15 ng/dL based on the prior data of a prospective observational study. In the CKD cohort study (n = 141), baseline plasma aldosterone concentration was identified as an independent contributory factor for the future rate of change in estimated glomerular filtration rate (eGFR). When the cut-off value for aldosterone was set at 14.5 ng/dL, the decline rate was significantly higher in patients with higher plasma aldosterone concentration (− 1.22 ± 0.39 ml/min/1.73 m2/year vs. 0.39 ± 0.40 ml/min/1.73 m2/year, p = 0.0047). In the final intervention study, in the eplerenone group, eGFR dropped at 6 months after the initiation of the study, and thereafter eGFR was maintained until the end of the study. At 24 months and 36 months, eGFR was significantly higher in the eplerenone group than in the placebo group. In conclusion, MRA can be an effective strategy in preventing CKD progression, especially in patients with high plasma aldosterone.

Abstract
BACKGROUND AND OBJECTIVES The progression of kidney disease in some patients with type 2 diabetes mellitus may not be adequately suppressed by renin-angiotensin system inhibitors. Esaxerenone (CS-3150) is a nonsteroidal mineralocorticoid receptor blocker that has shown kidney protective effects in preclinical studies, and it is a potential add-on therapy to treat diabetic kidney disease. This phase 2 study evaluated the efficacy and safety of esaxerenone in Japanese patients with type 2 diabetes mellitus and microalbuminuria. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This multicenter, randomized, double-blind, placebo-controlled trial enrolled 365 hypertensive or normotensive patients with type 2 diabetes mellitus and microalbuminuria (urinary albumin-to-creatinine ratio ≥45 to <300 mg/g creatinine) treated with renin-angiotensin system inhibitor who had eGFR≥30 ml/min per 1.73 m2. Participants were randomized to receive 0.625, 1.25, 2.5, or 5 mg/d esaxerenone or placebo for 12 weeks. The primary end point was the change in urinary albumin-to-creatinine ratio from baseline to week 12 (with last observation carried forward). RESULTS Esaxerenone treatment at 1.25, 2.5, and 5 mg/d significantly reduced urinary albumin-to-creatinine ratio by the end of treatment (38%, 50%, and 56%, respectively) compared with placebo (7%; all P<0.001). The urinary albumin-to-creatinine ratio remission rate (defined as urinary albumin-to-creatinine ratio <30 mg/g creatinine at the end of treatment and ≥30% decrease from baseline) was 21% in the 2.5- and 5-mg/d groups versus 3% for placebo (both P<0.05). Adverse events occurred slightly more frequently with esaxerenone versus placebo, but the frequencies of drug-related adverse events and discontinuation rates were similar in the placebo and the 0.625-, 1.25-, and 2.5-mg/d groups. Drug-related adverse events and treatment discontinuations were marginally higher in the 5-mg/d group. The most common drug-related adverse event was hyperkalemia, which was dose proportional. CONCLUSIONS Adding esaxerenone at 1.25, 2.5, and 5 mg/d for 12 weeks to an ongoing renin-angiotensin system inhibitor significantly reduces urinary albumin-to-creatinine ratio in patients with type 2 diabetes mellitus and microalbuminuria.

Abstract
This was a phase 2, multicenter, randomized, double-blind, placebo-controlled, open-label comparator study to investigate the efficacy and safety of esaxerenone (CS-3150), a novel non-steroidal mineralocorticoid receptor blocker, in Japanese patients with essential hypertension. Eligible patients (n = 426) received esaxerenone (1.25, 2.5, or 5 mg/day), placebo, or eplerenone (50–100 mg/day) for 12 weeks. The primary efficacy endpoint was the change from baseline in sitting systolic and diastolic blood pressure (BP). Safety endpoints included adverse events and serum K+ elevation. There were significant dose–response reductions in the 2.5 and 5 mg/day esaxerenone groups for sitting BP (both p < 0.001) and 24-h BP (both p < 0.0001) compared with placebo, with a mean (95% confidence interval) change in sitting BP of −7.0 (−9.5 to −4.6)/−3.8 (−5.2 to −2.4) mmHg in the placebo group, and −10.7 (−13.2 to −8.2)/−5.0 (−6.4 to −3.6) mmHg, −14.3 (−16.8 to −11.9)/−7.6 (−9.1 to −6.2) mmHg, and −20.6 (−23.0 to −18.2)/ −10.4 (−11.8 to −9.0) mmHg for the 1.25, 2.5, and 5 mg/day esaxerenone groups, respectively, while the change was −17.4 (−19.9 to −15.0)/−8.5 (−9.9 to −7.1) mmHg for eplerenone. The incidence of adverse events was similar in all treatment groups. Serum K+ levels initially increased in proportion with esaxerenone dose but were stable from week 2 until week 12. Plasma esaxerenone concentration increased in proportion with the dose. In conclusion, esaxerenone is an effective and tolerable treatment option for patients with essential hypertension.

Abstract
Cardiovascular disease is the leading cause of death in patients with chronic renal disease and the most common cause of death and allograft loss among kidney transplant recipients. Transplant patients often have multiple cardiovascular risk factors antedating transplantation. Among the most prominent is hypertension (HTN), which affects at least 90% of transplant patients. Uncontrolled HTN is an independent risk factor for allograft loss. The etiology of HTN in transplant recipients is complex and multifactorial, including the use of essential immunosuppressive medications. Post-transplant HTN management requires a systematic and individualized approach with nonpharmacologic and pharmacologic therapies. There is no single ideal agent or treatment algorithm. Patients should regularly monitor and record their blood pressure at home. Often, multiple antihypertensive drugs are needed to achieve a goal blood pressure of 120-140/70-90 mm Hg. As transplant recipients commonly must take 8 to 12 different medications daily, adherence must be continually encouraged and monitored. Special attention must be paid to potential drug side effects and drug interactions with immunosuppressive medications.

Abstract
Postmenopausal hypertensive is associated with estrogen deficiency. This meta-analysis was performed to assess the efficacy and safety of drospirenone combined with 17-β-estradiol (DRSP/E2) in postmenopausal hypertensive women. A systemic literature search of PubMed, Embase, Cochrane Library, Web of Science (up to Oct. 2015) was performed. Studies were screened independently by two researchers according to the inclusion and exclusion criteria which included only the randomized controlled trials (RCT) about the drospirenone with 17-β-estradiol for postmenopausal women with hypertension. The methodological quality was evaluated by Cochrane handbook 5.1.0 and meta-analysis was conducted using RevMan 5.3.0 software. Five randomized controlled trials involved 1121 patients who met the eligibility criteria. Overall, DRSP/E2 group was superior in reducing clinical blood pressure (BP) and 24-h mean BP. There was no significant change in potassium levels on DRSP/E2 group versus control group, suggesting probability potassium sparing effect of this hormone therapy. The incidences of adverse events were low and similar. The current evidences indicate that DRSP 3 mg/E2 2 mg can significantly lower both systolic and diastolic blood pressure in postmenopausal hypertensive women.

Abstract
Progression of chronic kidney disease (CKD) is inevitable. However, the last decade has witnessed tremendous achievements in this field. Today we are optimistic; the dream of withholding this progression is about to be realistic. The recent discoveries in the field of CKD management involved most of the individual diseases leading the patients to end-stage renal disease. Most of these advances involved patients suffering diabetic kidney disease, chronic glomerulonephritis, polycystic kidney disease, renal amyloidosis and chronic tubulointerstitial disease. The chronic systemic inflammatory status and increased oxidative stress were also investigated. This inflammatory status influences the anti-senescence Klotho gene expression. The role of Klotho in CKD progression together with its therapeutic value are explored. The role of gut as a major source of inflammation, the pathogenesis of intestinal mucosal barrier damage, the role of intestinal alkaline phosphatase and the dietary and therapeutic implications add a novel therapeutic tool to delay CKD progression.

Abstract
Patients with chronic kidney disease (CKD) suffer from an increased prevalence of cardiovascular disease (CVD) risk factors, and a high rate of premature CV morbidity and mortality. The confluence of CV risk factors, in the context of cardio-metabolic perturbations that vary as renal function declines, complicates strategies for the care of patients with CKD. Understanding the existing evidence for effective CVD treatment strategies can help providers better care for these patients, navigate the complex treatment guidelines, which often differ across major organizations, and minimize the conflicting recommendations that new studies may pose. A pragmatic approach is to target a BP <140/90 mm Hg, which frequently requires more than two or three antihypertensive agents. Most guidelines recommend a combination of diuretic and angiotensin converting enzyme inhibitor or angiotensin receptor blockers, along with a dihydropyridine calcium channel blocker, beta blocker or other agent based on co-existing medical conditions. Consideration for a lower BP goal and/or other therapeutic interventions should be based on the etiology of CKD, stage of CKD, and/or presence of proteinuria. Finally, most patients with CKD, not on dialysis, would benefit from treatment with statins and non-pharmacologic lifestyle interventions should be promoted for all patients with CKD.

Abstract
BACKGROUND/AIMS Acute kidney injury (AKI) frequently occurs in hospitalized patients. In this study, we determined prehospitalization characteristics associated with AKI in community-dwelling adults hospitalized for a serious infection. METHODS We used prospective data from 30,239 participants of the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, a national cohort of community-dwelling adults ≥45 years old. We identified serious infection hospitalizations between 2003 and 2012. Using the Kidney Disease Improving Global Outcomes (KDIGO) criteria, we defined AKI as an increase in serum creatinine (sCr) ≥0.3 mg/dl from the first inpatient sCr measurement during the first 7 hospitalization days. We excluded individuals with a history of renal transplant or preexisting end-stage renal disease as well as individuals with <2 sCr measurements. We identified baseline characteristics (sociodemographics, health behaviors, chronic medical conditions, biomarkers, and nonsteroidal anti-inflammatory, statin, or antihypertensive medication use) independently associated with AKI events using multivariable generalized estimating equations. RESULTS Over a median follow-up of 4.5 years (interquartile range 2.4-6.3), we included 2,074 serious infection hospitalizations among 1,543 individuals. AKI occurred in 296 of 2,074 hospitalizations (16.5%). On multivariable analysis, prehospitalization characteristics independently associated with AKI among individuals hospitalized for a serious infection included a history of diabetes [odds ratio (OR) 1.38; 95% CI 1.02-1.89], increased cystatin C (OR 1.73 per SD; 95% CI 1.20-2.50), and increased albumin-to-creatinine ratio (OR 1.19 per SD; 95% CI 1.007-1.40). Sex, race, hypertension, myocardial infarction, estimated glomerular filtration rate, high-sensitivity C-reactive protein, and the use of nonsteroidal anti-inflammatory, statin, or antihypertensive medications were not associated with AKI. CONCLUSIONS Community-dwelling adults with a history of diabetes or increased cystatin C or albumin-to-creatinine ratio are at increased risk for AKI after hospitalization for a serious infection. These findings may be used to identify individuals at high risk for AKI.

Diverse diuretics regimens differentially enhance the antialbuminuric effect of renin-angiotensin blockers in patients with chronic kidney disease. Kidney Int 2015; 88:1434-1441.

Abstract
The addition of spironolactone or hydrochlorothiazide enhances the antialbuminuric effect of renin-angiotensin blockers. However, comparative studies on the effect of different diuretics are lacking. We conducted a prospective randomized crossover study to compare the effects of spironolactone (25 mg/day), hydrochlorothiazide (50 mg/day) without/with amiloride (5 mg/day) on top of enalapril treatment in 21 patients with CKD stages 1-3 and a urinary albumin-to-creatinine ratio (UACR) over 300 mg/g. Treatment periods lasted 4 weeks. The UACR showed a significant reduction with the diuretics: spironolactone, -34% or hydrochlorothiazide without/with amiloride -42% or -56%, respectively. Reduction of the UACR was significantly greater with hydrochlorothiazide without/with amiloride when compared with spironolactone. The percentage of patients who achieved UACR reductions greater than 30% and 50% was greater with hydrochlorothiazide without/with amiloride (81% and 57%, and 81% and 66%, respectively) when compared with spironolactone alone (57% and 28%, respectively). Glomerular filtration rate (GFR), blood pressure, and body weight decreased with the three diuretic regimens. A significant correlation was found between the UACR reduction and GFR and blood pressure changes. Thus, diverse diuretic regimens differentially enhance albuminuria reduction, an effect likely associated with the degree of GFR reduction.

Abstract
The purpose of this 2-year multicentric, randomized, placebo-controlled study was to evaluate the long-term effects and adverse effects of spironolactone on chronic dialysis patients. A total of 253 non-heart failure dialysis patients with end-stage renal disease were randomly assigned to 2-year treatment with spironolactone (25 mg once daily, n=125) or a matching placebo (n=128) as add-on therapy. The primary outcome was a composite of death from cardiocerebrovascular (CCV) events, aborted cardiac arrest, and sudden cardiac death, and the secondary outcome was death from all causes. Other CCV-related indexes such as left ventricular mass index, left ventricular ejection fraction, heart rate variability, vascular endothelial function, and blood pressure-lowering effect were analyzed for patients who completed the whole 2-year follow-up study. Sociodemographic, clinical, and relevant laboratory data were also collected. During the 2-year follow-up, the primary outcome occurred less frequently in the spironolactone group vs the control group (7.2% vs 18.0%; adjusted hazard ratio [HR], 0.42; 95% confidence interval [CI], 0.26-0.78). Death from CCV events occurred in 4.0% of patients in the spironolactone group and in 11.7% of patients in the control group. Neither aborted cardiac arrest nor sudden cardiac death was significantly reduced by spironolactone treatment. The secondary outcome occurred less frequently in the spironolactone group vs the control group (9.6% vs 19.5%; adjusted HR, 0.52; 95% CI, 0.29-0.94). Other CCV-related indexes except for heart rate variability were significantly improved. This study demonstrates that use of low-dose spironolactone in non-heart failure dialysis patients can effectively reduce the risks of both CCV morbidity and mortality with few side effects. Moreover, the beneficial effect was mediated through improving the endothelial function or reducing left ventricular size independent of blood pressure changes, rather than mediation through changes in salt or potassium handling in the kidney.

Drug therapy of apparent treatment-resistant hypertension: focus on mineralocorticoid receptor antagonists. Drugs 2015; 75:473-85.

Abstract
Apparent treatment-resistant hypertension (aTRH) is defined as blood pressure (BP) >140/90 mmHg despite three different antihypertensive drugs including a diuretic. aTRH is associated with an increased risk of cardiovascular events, including stroke, chronic renal failure, myocardial infarction, congestive heart failure, aortic aneurysm, atrial fibrillation, and sudden death. Preliminary studies of renal nerve ablation as a therapy to control aTRH were encouraging. However, these results were not confirmed by the Symplicity 3 trial. Therefore, attention has refocused on drug therapy. Secondary forms of hypertension and associated conditions such as obesity, sleep apnea, and primary aldosteronism are common in patients with aTRH. The pivotal role of aldosterone in the pathogenesis of aTRH in many cases is well recognized. For patients with aTRH, the Joint National Committee-8, the European Society of Hypertension, and a recent consensus conference recommend that a diuretic, ACE inhibitor, or angiotensin receptor blocker and calcium channel blocker combination be used to maximally tolerated doses before starting a 'fourth-line' drug such as a mineralocorticoid receptor (MR) antagonist. Although the best fourth-line drug for aTRH has not been extensively investigated, a number of studies summarized here show that an MR antagonist is effective in reducing BP when added to the standard multi-drug regimen.
