Potential Role of Mineralocorticoid Receptor Antagonists in Nondiabetic Chronic Kidney Disease and Glomerular Disease.

Glomerular disease is a leading cause of CKD and ESKD. Although diabetic kidney disease is the most common cause of glomerular disease, nondiabetic causes include malignancy, systemic autoimmune conditions, drug effects, or genetic conditions. Nondiabetic glomerular diseases are rare diseases, with a paucity of high-quality clinical trials in this area. Furthermore, late referral can result in poor patient outcomes. This article reviews the current management of nondiabetic glomerular disease and explores the latest developments in drug treatment in this area. Current treatment of nondiabetic glomerular disease aims to manage complications (edema, hypertension, proteinuria, hyperlipidemia, hypercoagulability, and thrombosis) as well as target the underlying cause of glomerular disease. Treatment options include renin-angiotensin-aldosterone system inhibitors, statins/nonstatin alternatives, loop diuretics, anticoagulation agents, immunosuppressives, and lifestyle and dietary modifications. Effective treatment of nondiabetic glomerular disease is limited by heterogeneity and a lack of understanding of the disease pathogenesis. Sodium-glucose cotransporter-2 inhibitors and nonsteroidal mineralocorticoid receptor antagonists (ns-MRAs, such as finerenone), with their broad anti-inflammatory and antifibrotic effects, have emerged as valuable therapeutic options for a range of cardiorenal conditions, including CKD. ns-MRAs are an evolving drug class of particular interest for the future treatment of nondiabetic glomerular disease, and there is evidence that these agents may improve kidney prognosis in various subgroups of patients with CKD. The benefits offered by ns-MRAs may present an opportunity to reduce the progression of CKD from a spectrum of glomerular disease. Several novel ns-MRA are in clinical development for both diabetic and nondiabetic CKD.

A review of novel endothelin antagonists and overview of non-steroidal mineralocorticoid antagonists for treating resistant hypertension: An update

Several agents are emerging from five different novel classes of antihypertensive medications. We will focus on endothelin antagonists and non-steroidal mineralocorticoid receptor antagonists. While several agents exist in this later class, only a couple have demonstrated superior efficacy in resistant hypertension management. Endothelin receptor antagonists are effective therapy for primary and resistant hypertension, but they are not widely used. This is due to side effects demonstrated in large clinical trials, specifically increased peripheral edema and worsening heart failure in some cases, as well as the availability of many alternative agents to manage blood pressure effectively. However, the relationship between endothelin and its close ties to hypertension is evolving. Recent pre-clinical work explores new applications of more selective endothelin receptor antagonists. They suggest that specific subtypes of hypertension may benefit more from endothelin receptor blockade than simply those with primary hypertension. We review this topic and other related data. Lastly, we also provide a brief overview of non-steroidal mineralocorticoid receptor antagonists as some in the class show promise as antihypertensive agents.

Discovering novel targets of abscisic acid using computational approaches

Abscisic acid (ABA) is a crucial plant hormone that is naturally produced in various mammalian tissues and holds significant potential as a therapeutic molecule in humans. ABA is selected for this study due to its known roles in essential human metabolic processes, such as glucose homeostasis, immune responses, cardiovascular system, and inflammation regulation. Despite its known importance, the molecular mechanism underlying ABA's action remain largely unexplored. This study employed computational techniques to identify potential human ABA receptors. We screened 64 candidate molecules using online servers and performed molecular docking to assess binding affinity and interaction types with ABA. The stability and dynamics of the best complexes were investigated using molecular dynamics simulation over a 100 ns time period. Root mean square fluctuations (RMSF), root mean square deviation (RMSD), solvent-accessible surface area (SASA), radius of gyration (Rg), free energy landscape (FEL), and principal component analysis (PCA) were analyzed. Next, the molecular mechanics Poisson–Boltzmann surface area (MM-PBSA) method was employed to calculate the binding energies of the complexes based on the simulated data. Our study successfully pinpointed four key receptors responsible for ABA signaling (androgen receptor, glucocorticoid receptor, mineralocorticoid receptor, and retinoic acid receptor beta) that have a strong affinity for binding with ABA and remained structurally stable throughout the simulations. The simulations with Hydralazine as an unrelated ligand were conducted to validate the specificity of the identified receptors for ABA. The findings of this study can contribute to further experimental validation and a better understanding of how ABA functions in humans.

The potential role of finerenone in patients with type 1 diabetes and chronic kidney disease.

Chronic kidney disease (CKD) represents a global health concern, associated with an increased risk of cardiovascular morbidity and mortality and decreased quality of life. Many patients with type 1 diabetes (T1D) will develop CKD over their lifetime. Uncontrolled glucose levels, which occur in patients with T1D as well as type 2 diabetes (T2D), are associated with substantial mortality and cardiovascular disease burden. T2D and T1D share common pathological features of CKD, which is thought to be driven by haemodynamic dysfunction, metabolic disturbances, and subsequently an influx of inflammatory and profibrotic mediators, both of which are major interrelated contributors to CKD progression. The mineralocorticoid receptor is also involved, and, under conditions of oxidative stress, salt loading and hyperglycaemia, it switches from homeostatic regulator to pathophysiological mediator by promoting oxidative stress, inflammation and fibrosis. Progressive glomerular and tubular injury leads to macroalbuminuria a progressive reduction in the glomerular filtration rate and eventually end-stage renal disease. Finerenone, a non-steroidal, selective mineralocorticoid receptor antagonist, is approved for treatment of patients with CKD associated with T2D; however, the benefit of finerenone in patients with T1D has yet to be determined. This narrative review will discuss treatment of CKD in T1D and the potential future role of finerenone in this setting.

A Randomized trial assessing Efficacy and safety of Mineralocorticoid receptor Antagonist therapy compared to Standard antihypertensive Therapy in hypErtension with low Renin (REMASTER): rationale and study design

Low-renin hypertension affects 1 in 4 people with hypertension, but the optimal management of this condition is not known. We hypothesize that a large proportion of people with low-renin hypertension is mediated by excess mineralocorticoid receptor (MR) activation and that targeted treatment with an MR antagonist (MRA) will be beneficial. This randomized, single-blinded, titration-to-effect aims to investigate whether targeted treatment in low-renin hypertension with MRA is better compared to standard antihypertensives in terms of blood pressure control and end-organ protection. Adults with hypertension, who are treatment naïve or are receiving up to two antihypertensive agents and have a low direct renin concentration <10 mU/L will be included. Participants with severe hypertension, a secondary cause of hypertension, pregnant, breastfeeding, with moderate-severe cardiovascular and chronic kidney disease, or on medications that confound interpretation of the plasma direct renin or aldosterone concentrations will be excluded. Eligible participants will be randomized 1:1 to either MRA therapy (spironolactone) or standard anti-hypertensive therapy (perindopril+/− amlodipine) for 48 weeks. Anti-hypertensives will be up-titrated every 12 weeks until target blood pressure is achieved. The primary objective will be to determine the total defined daily dose of antihypertensives required to achieve the target blood pressure and change in mean clinic systolic blood pressure at week 48. Current hypertension guidelines do not have specific recommendations for the choice of anti-hypertensive medications for people with low-renin hypertension. The results of this trial could guide future hypertension guidelines.

Safety and Tolerability of Initiating Sacubitril-Valsartan With Spironolactone During Hospitalization for Acute Decompensated Heart Failure.

Background: Initiation of sacubitril-valsartan and mineralocorticoid receptor antagonists (MRA) during hospitalization for acute decompensated heart failure (ADHF) may be an ideal time to optimize guideline-directed medical therapy. However, there is limited research assessing the safety of combining these agents in the hospital. Methods: This was a multi-center, retrospective, propensity-score matched cohort study performed at 7 acute-care hospitals within a large health care system. All adult patients admitted with ADHF between January 1, 2019 to December 31, 2021 who received sacubitril-valsartan with MRA (MRA group) or without MRA (non-MRA group) and had a left ventricular ejection fraction (LVEF) < 40% were included in the study. Results: 220 patients were screened during the study time frame with 179 meeting inclusion criteria. Following propensity-score matching, 50 patients in the MRA group were matched to 50 patients in the non-MRA group. The overall incidence of adverse drug reactions (ADRs) was 24% in the non-MRA group compared to 20% in the MRA group (P = .629). There was a significantly greater incidence of hyperkalemia in the MRA group (0% vs 10%; P = .022). None of the patients in the non-MRA group were readmitted within 30 days due to an ADR compared to 6% in the MRA group (P = .079). Conclusion: The addition of spironolactone to sacubitril-valsartan in the hospital setting following stabilization of ADHF did not lead to a significantly greater incidence of overall ADRs, but patients were more likely to develop hyperkalemia and there was a numerically higher incidence of 30-day readmissions due to ADRs.

Challenges to heart failure medication prescribing post-hospitalization.

To determine the prevalence of heart failure (HF) medication prescribing on discharge post-HF-related admission. A retrospective audit was conducted for 216 HF admissions over a period of 6 months; medication data from electronic records were collected for analysis. The prevalence of HF medication prescribing on discharge was: 32.9% (95% confidence interval: 26.6-39.6) renin-angiotensin-aldosterone system inhibitors, 10.6% (6.9-15.6) angiotensin receptor-neprilysin inhibitors, 31.5% (25.4-38.1) HF-specific beta-blockers, 42.6% (35.9-49.5) aldosterone receptor antagonists, and 11.6% (7.6-16.6) sodium-glucose cotransporter-2 inhibitors. HF medication prescribing remains relatively low despite the known benefits and recommendations listed in the guidelines.

New ways of mitigating aldosterone in cardiorenal disease.

Steroidal mineralocorticoid receptor antagonists (MRAs) bind to the mineralocorticoid receptor and antagonize the effects of aldosterone, which contributes to the development and progression of cardio- and renovascular diseases. Guidelines recommend steroidal MRAs in patients with heart failure with reduced or mildly reduced ejection fraction, as they reduce morbidity and mortality. In heart failure with preserved ejection fraction, MRAs have not convincingly shown to improve prognosis. Steroidal MRAs delay the progression of chronic kidney disease, reduce proteinuria and lower blood pressure in resistant hypertension but can induce hyperkalaemia. Due to their limited selectivity to the mineralocorticoid receptor, steroidal MRAs can cause significant adverse effects, i.e. libido loss, erectile dysfunction, gynaecomastia, and amenorrhoea, leading to low rates of persistance. Against this background, new avenues for developing non-steroidal, selective (ns)MRAs and aldosterone-synthase inhibitors have been taken. Finerenone has been shown to delay the progression of diabetic nephropathy and lower the incidence of heart failure hospitalizations in patients with chronic kidney disease and diabetes compared with placebo. Finerenone has therefore been recommended by the 2023 European Society of Cardiology Guidelines for the management of diabetes in patients with type 2 diabetes and chronic kidney disease. Further randomized controlled trials assessing the safety and effectiveness of finerenone in patients with heart failure are currently ongoing. Esaxerenone provides antihypertensive effects and has been approved for the treatment of hypertension in Japan. Baxdrostat and lorundostat, novel selective aldosterone-synthase inhibitors, are currently under investigation. In phase II trials, baxdrostat and lorundostat were safe and effective in lowering blood pressure in resistant hypertension. In this review, we summarize and critically discuss the evidence for new drugs mitigating aldosterone in heart failure, hypertension, and chronic kidney disease.

Epithelial Na + Channel Activation after Bile Duct Ligation with Mineralocorticoid Receptor Blockade.

Sodium and fluid retention in liver disease are classically thought to result from reduced effective circulating volume and stimulation of the renin-angiotensin-aldosterone system (RAAS). However, evidence of fluid retention in patients without RAAS activation suggests the involvement of additional mechanisms. In vitro, bile acids activate the epithelial Na+ channel (ENaC) found in the aldosterone-sensitive distal nephron. If this occurs in vivo, ENaC may become activated in liver disease even with antagonism of aldosterone signaling. To test this, we performed bile duct ligation to induce liver disease and increase circulating bile acids in mice given spironolactone to antagonize aldosterone signaling. We analyzed effects on blood, urine and body composition. We also determined the effects of taurocholic acid, a primary conjugated bile acid elevated in liver disease, on ion fluxes in microperfused rabbit collecting ducts. Bile duct ligation increased benzamil-sensitive natriuresis compared to sham, indicating ENaC activation. These effects were not explained by effects on ENaC expression, cleavage, or localization. Bile duct ligated mice also gained significantly more fluid than sham-operated animals. Blocking ENaC reversed fluid gains in bile duct ligated mice but had no effect in shams. In dissected collecting ducts from rabbits, which express ENaC, taurocholic acid stimulated net Na+ absorption. Our results provide experimental evidence for a novel aldosterone-independent mechanism for sodium and fluid retention in liver disease.

Effectiveness and safety of finerenone in Chinese CKD patients without diabetes: a retrospective, real-world study

BackgroundFinerenone, a non-steroidal mineralocorticoid receptor antagonist, has previously demonstrated its efficacy and safety in chronic kidney disease (CKD) associated with diabetes mellitus. Given its therapeutic potential, finerenone has been preliminarily explored in clinical practice for non-diabetic CKD patients. The effectiveness and safety in this population require further investigation in a real-world setting.MethodsThis retrospective, real-world analysis included non-diabetic CKD patients receiving finerenone. The main clinical outcomes assessed were changes in urinary albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR). Serum potassium (sK+) levels were also monitored. Data were collected at baseline, and then at 1 month and 3 months following treatment initiation.ResultsTotally, 16 patients were included. There was a notable decrease in UACR from 1-month post-treatment, with a further reduction at 3 months, resulting in a median reduction of 200.41 mg/g (IQR, 84.04–1057.10 mg/g; P = 0.028; percent change, 44.52% [IQR, 31.79–65.42%]). The average eGFR at baseline was 80.16 ml/min/1.73m2, with no significant change after 1 month (80.72 ml/min/1.73m2, P = 0.594) and a slight numerical increase to 83.45 ml/min/1.73m2 (P = 0.484) after 3 months. During the 3-month follow-up, sK+ levels showed only minor fluctuations, with no significant differences compared to baseline, and remained within the normal range throughout the treatment period. No treatment discontinuation or hospitalization due to hyperkalemia was observed.ConclusionIn non-diabetic CKD patients, finerenone showed good effectiveness and safety within a 3-month follow-up period. This study provides valuable real-world evidence supporting the use of finerenone in non-diabetic CKD and highlights the need for future large-scale prospective research to further validate its efficacy.

Cardiovascular and non-renal complications of chronic kidney disease: Managing risk.

Chronic kidney disease (CKD) currently affects approximately 850 million people globally and is continuing to increase in prevalence as well as in importance as a cause of death. The excess mortality related to CKD is mostly caused by an increase in cardiovascular disease. This includes atherosclerotic cardiovascular disease as many promoters of atherosclerosis, such as blood pressure, lipid levels and hypercoagulation, are increased in people with CKD. Diabetes is a leading cause of CKD contributing to the risk of CVD, and obesity is also increasingly prevalent. Management of these risk factors is therefore very important in CKD, and to reduce risk of CKD progression. Heart failure is also more prevalent in CKD and, again, many risk factors are shared. The concept of foundational pillars in the management of heart failure has been adapted to the treatment of CKD, with many organ-protective interventions, such renin-angiotensin system blockade, sodium-glucose cotransporter-2 inhibition and mineralocorticoid receptor antagonism, reducing the risk for mortality in heart failure with reduced ejection fraction, but also for progression of CKD. Atrial fibrillation is also more common with CKD and affects the management of the former. In this review these non-renal complications of CKD are discussed, along with how the risk of these complications should be managed. Many new opportunities have demonstrated heart and kidney organ protection, but implementation is a challenge.

Finerenone: Who should prescribe it for CKD? The physician associate's perspective.

Diabetic kidney disease (DKD) affects 30-40% of all patients with diabetes and contributes significantly to the cardiovascular burden of chronic kidney disease (CKD). Despite the availability of evidence-based medications like finerenone and simple screening tests such as Urinary Albumin-to-Creatinine Ratio (UACR), more resources are still needed to care for DKD patients. Physician Associates (PAs) play a crucial role in the multidisciplinary team responsible for DKD diagnosis, monitoring, and management. A nonsteroidal mineralocorticoid receptor antagonist, namely finerenone, was approved by the FDA in adults with CKD associated with type 2 diabetes to reduce the risk of renal and cardiovascular outcomes. Finerenone is considered among the pillars of care for DKD, furthermore, the addition of finerenone in combination with renin-angiotensin system inhibitors and/or other renal protective medications may offer additional benefits. Primary care providers prescribe finerenone less frequently than specialized care providers, indicating a need to empower physician associates in medication prescription and other renal protection strategies. As part of a multidisciplinary team, physician associates can play an important role in evaluating risk factors that contribute to heart disease and metabolic health. They can also monitor not only kidney function by ordering tests, such as serum creatinine and urinary albumin-to-creatinine ratio every 3-12months, but also serum potassium levels. Additionally, physician associates can encourage patients to take responsibility for their health by regularly monitoring their blood pressure, blood glucose levels, and body weight. With early detection and management, kidney failure and cardiovascular events may be preventable. Specialized physician associates also play a significant role in the comprehensive care of DKD patients, especially in the later stages. DKD care can be hindered by numerous factors such as lack of patient engagement during counseling, cost disparities, and a complex referral system that requires multidisciplinary guidelines to improve professional communication. It is necessary to re-envision the physician associates' role in primary care and empower them in goal-directed therapies.

From pathophysiology to personalized care: A comprehensive review of diabetic kidney disease

Diabetic kidney disease (DKD) stands as a prevalent and significant complication in individuals with type 2 diabetes, impacting nearly half of this population. It holds the primary position as the cause of chronic kidney disease and end-stage kidney disease globally, associated with heightened cardiovascular morbidity and mortality. Despite the array of available interventions to prevent and manage DKD, such as regulating blood sugar levels, controlling blood pressure, and inhibiting the renin-angiotensin system, numerous patients continue to grapple with the ongoing decline in kidney function and unfavorable outcomes. This comprehensive review offers an updated exploration of the pathophysiology, diagnosis, prevention, and treatment of DKD. Special attention is devoted to emerging treatment modalities displaying promising outcomes in clinical trials, notably sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, non-steroidal mineralocorticoid receptor antagonists, and innovative agents addressing inflammation and fibrosis. The discourse also delves into the complexities and opportunities associated with integrating these therapies into clinical practice, emphasizing the necessity for personalized and all-encompassing care for DKD patients. The conclusion outlines future directions, urging further research and providing recommendations to advance both understanding and practical approaches in this domain.

Aldosterone Effect on Cardiac Structure and Function.

Cardiac remodelling could be a key mechanism in aldosteronemediated cardiovascular morbidity and mortality. Experimental and clinical evidence has demonstrated that aldosterone causes cardiac structural remodelling and dysfunction by its profibrotic and pro-hypertrophic effects, which result mainly from the direct effects on myocardial collagen deposition, inflammation, and oxidative stress. Clinical studies have investigated the aldosterone effects on the heart in different clinical conditions, including general population, essential hypertension, primary aldosteronism, heart failure, and atrial fibrillation. Robust findings indicate that aldosterone or the activation of the cardiac mineralocorticoid receptor can cause damage to myocardial tissue by mechanisms independent of the blood pressure, leading to tissue hypertrophy, fibrosis, and dysfunction. Aldosterone-mediated cardiovascular morbidity and mortality mainly result from cardiac structural and functional alterations. In different clinical settings, aldosterone can induce cardiac structural remodelling and dysfunction via several pathological mechanisms, including cardiac fibrosis, inflammation, and oxidative stress. Aldosterone antagonists could effectively decrease or reverse the detrimental aldosterone-mediated changes in the heart.

Ongoing and Future Clinical Trials of Pharmacotherapy for Heart Failure.

Increasing knowledge of the processes leading to heart failure (HF) has allowed significant developments in therapies for HF over the past few decades. Despite the evolution of HF treatment, it still places a large burden on patients and health care systems across the world.We used clinicaltrials.gov to gather information about clinical trials as of August 2023 studying pharmacotherapy for HF. We included interventional trials that were "active, not recruiting", "recruiting", or looking for participants but "not yet recruiting". In total, 119 studies met our criteria of ongoing clinical trials studying novel as well as currently approved HF pharmacotherapies. The major interventions were novel medications/already approved medications for other diseases 29 % (34 trials), sodium-glucose co-transporter inhibitors 21 % (25 trials), angiotensin receptor blocker-neprilysin inhibitors 10 % (12 trials), diuretics 14 % (17 trials) and mineralocorticoid receptor antagonists 5 % (6 trials). Ongoing research will aid in reducing the impact of HF and we summarize clinical trials leading the way to better HF treatment in this review.

The Renin-Angiotensin-Aldosterone System Regulates Sarcoidosis Granulomatous Inflammation.

Rationale: Sarcoidosis is a granulomatous disorder of unclear cause notable for abnormal elevation of blood and tissue ACE1 (angiotensin converting enzyme 1) levels and activity. ACE1 regulates the renin-angiotensin-aldosterone system (RAAS), the terminal product of which is aldosterone, which selectively engages mineralocorticoid receptors to promote inflammation. Objectives: We sought to determine whether the RAAS promotes sarcoidosis granuloma formation and related inflammatory responses. Methods: Using an established ex vivo model, we first determined whether aldosterone was produced by sarcoidosis granulomas and verified the presence of CYP11B2, the enzyme required for its production. We then evaluated the effects of selective inhibitors of ACE1 (captopril), angiotensin type 1 receptor (losartan), and mineralocorticoid receptors (spironolactone, eplerenone) on granuloma formation, reflected by computer image analysis-generated granuloma area, and selected cytokines incriminated in sarcoidosis pathogenesis. Measurements and Main Results: Aldosterone was spontaneously produced by sarcoidosis peripheral blood mononuclear cells, and both intra- and extracellular levels steadily increased during granuloma formation. In parallel, peripheral blood mononuclear cells were shown to express more CYP11B2 during granuloma formation. Significant inhibition of sarcoidosis granulomas and related cytokines (TNFα, IL-1β, IFNγ, IL-10) was observed in response to pretreatments with captopril, losartan, spironolactone, or eplerenone, comparable to that of prednisone. Conclusions: The RAAS is intact in sarcoidosis granulomas and contributes significantly to early granuloma formation and to related inflammatory mediator responses, with important implications for clinical management.

The Early Diagnosis and Treatment of Chronic Renal Insufficiency.

Chronic renal insufficiency (CRI) is becoming more common and has an increasing impact on public health. In Germany, approximately one in ten adults has CRI. Its most serious consequence is generally not the development of end-stage renal failure, but rather the markedly increased cardiovascular risk as kidney function declines. This review is based on the findings of a selective search in PubMed for literature about the treatment options for CRI, and on our overview of the existing guideline recommendations on diagnostic testing. . Patients with diabetes mellitus and arterial hypertension are at especially high risk of developing CRI. For these patients, some of the guidelines recommend regular testing for albuminuria and measurement of the glomerular filtration rate (GFR), though sometimes only when specific risk constellations are present. The treatment of CRI has evolved in recent years. At first, aside from general measures, only RAS inhibitors were available as a specific therapy for CRI. With the extension of the approval of SGLT-2 inhibitors to non-diabetic CRI patients, the options for treatment have become wider. Two randomized controlled trials have revealed the benefit of SGLT-2 inhibitors with respect to their primary combined endpoints: time to a specified eGFR reduction and renal/cardiovascular death (HR 0.61 [0.51; 0.72] and 0.72 [0.64; 0.82]). The potential side effects and contraindications of SGLT-2 inhibitors must be taken into account. A further treatment option for diabetics with CRI has become available with the approval of the non-steroidal mineralocorticoid receptor antagonist finerenone. In patients with risk factors, renal function should be regularly tested.

Semaglutide in Chronic Kidney Disease: Great Enthusiasm. But How Does It Work?

Chronic Kidney Disease (CKD) is a clinical condition characterized by the progressive loss of kidney function. 10% of the world's population is affected by this condition, which represents the fifth leading cause of death globally. Furthermore, CKD is associated with increased risk of fatal and non-fatal cardiovascular events, and progression to end-stage renal disease. Over the last twenty years, an exponential growth in its prevalence and incidence has been observed. For this reason, various drugs have been developed and implemented in clinical practice, with various mechanisms, with the aim of reducing and minimizing this dramatic "cardio-renal" risk. These include SGLT2 inhibitors, mineralocorticoid receptor antagonists, and endothelin receptor antagonists. However, a large proportion of CKD patients do not respond sufficiently to these treatments. GLP-1 receptor agonists represent a class of antidiabetic and nephroprotective drugs that are very promising in improving the prognosis of patients with CKD, especially if associated with one of the above-mentioned classes. In this article, we discuss the direct and indirect mechanisms through which one of the GLP-1 agonists, semaglutide, ensures nephro- and cardioprotection in patients with CKD and type 2 diabetes.
