Abstract
BACKGROUND Renin-angiotensin-aldosterone system inhibitors (RAASIs) play a crucial role in the treatment of several chronic cardiovascular conditions. Nonetheless, hyperkalemia, a frequent side effect, often leads to the discontinuation of RAASIs. The implications of hyperkalemia-driven changes in RAASI medications are poorly understood. METHODS Population-based, observational, retrospective cohort study. Two large healthcare databases were utilized to identify 77,089 individuals aged 55 years and older with chronic conditions who were prescribed RAASIs between 2015 and 2017 in Southern Barcelona, Spain. We assessed the interplay between serum potassium abnormalities, RAASI management, and their associations with clinical outcomes, adjusting for potential confounders including socioeconomic factors, medical conditions, and potassium levels. RESULTS The one-year prevalence of hyperkalemia (defined as serum potassium, K+ >5.0 mmol/L) was 17.8 %. RAASI were down-titrated in 16.1 % of these 13,673 patients with K+ levels. Factors linked to a higher likelihood of reducing/discontinuing RAASI after developing hyperkalemia included older age, impaired kidney function, higher potassium levels, and previous hospitalizations. Dose reduction/discontinuation of RAASI after developing hyperkalemia was associated with an increased risk of hospitalization (adjusted hazard ratio [HR] 1.16, 95 % confidence interval [CI] 1.10-1.21) and with increased mortality (HR 1.60, 95 % CI 1.56-1.84). CONCLUSION In this large, observational study, hyperkalemia was linked to a greater likelihood of discontinuing RAASIs. Down-titration of RAASI was independently associated with unfavorable clinical outcomes such as hospitalization and specially mortality. Although the observational nature of the study, these findings underscore the importance of preventing circumstances that may lead to RAASI down-titration, such as hyperkalemia, as well as preventing hospitalizations and mortality, to ensure RAASI benefits.

Abstract
INTRODUCTION Chronic hyperkalemia has negative consequences in the medium and long term, and determines the suspension of nephro and cardioprotective drugs, such as renin-angiotensin-aldosterone system inhibitors (RAASi). There is an alternative to the suspension or dose reduction of these treatments: the administration of potassium chelators. The aim of this study is to estimate the economic impact of the use of patiromer in patients with chronic kidney disease (CKD) or heart failure (HF) and hyperkalemia in Spain. MATERIALS AND METHOD The annual economic impact of the use of patiromer has been estimated from the perspective of the Spanish society. Two scenarios were compared: patients with CKD or HF and hyperkalemia treated with and without patiromer. The costs have been updated to 2020 euros, using the Health Consumer Price Index. Direct healthcare costs related to the use of resources (treatment with RAASi, CKD progression, cardiovascular events and hospitalization due to hyperkalemia), direct non-healthcare costs (informal care: costs derived from time dedicated by patient's relatives), the indirect costs (productivity loss), as well as an intangible cost (due to premature mortality) were considered. A deterministic sensitivity analysis was performed to validate the robustness of the study results. RESULTS The mean annual cost per patient in the scenario without patiromer is €9,834.09 and €10,739.37 in CKD and HF, respectively. The use of patiromer would lead to cost savings of over 30% in both diseases. The greatest savings in CKD come from the delay in the progression of CKD. While in the case of HF, 80.1% of these savings come from premature mortality reduction. The sensitivity analyses carried out show the robustness of the results, obtaining savings in all cases. CONCLUSIONS The incorporation of patiromer allows better control of hyperkalemia and, as a consequence, maintain treatment with RAASi in patients with CKD or HF. This would generate a 32% of annual savings in Spain (€3,127 in CKD; €3,466 in HF). The results support the positive contribution of patiromer to health cost in patients with only CKD or in patients with only HF.

Abstract
PURPOSE OF REVIEW Clinical trials of the mineralocorticoid receptor antagonist (MRA) finerenone published recently suggest that they improve outcomes in patients with diabetic kidney disease (DKD). This review summarises key research from the last two years to provide clinicians with a synopsis of recent findings. RECENT FINDINGS Large international trials, such as Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease (5674 participants) and Finerenone in Reducing Cardiovascular Mortality and Morbidity in Diabetic Kidney Disease (7437 participants), suggest that in proteinuric patients with DKD and estimated glomerular filtration rate >25 ml/min/1.73 m2, already on renin-angiotensin-aldosterone system inhibitors, addition of finerenone provided modest further improvement in composite renal and cardiovascular outcomes. Proteinuria was reduced; there was also a small drop in systolic blood pressure. Hyperkalaemia remained a concern, although the incidence is lower with finerenone. Emerging data suggest that newer potassium binding agents may mitigate this risk. Preclinical studies suggest additive benefits when MRA and sodium-glucose co-transporter 2 (SGLT-2) inhibitors are used in combination. SUMMARY The nonsteroidal MRA finerenone could improve renal and cardiac outcomes further in diabetics with kidney disease when added to renin-angiotensin system inhibitors. Hyperkalaemia is probably less worrisome, but real-world data is needed. Combinations with other new nephroprotective agents (such as SGLT2i inhibitors) has the potential to provide increasing benefit. Benefits of finerenone in chronic kidney disease without diabetes remains to be seen.

Abstract
Hyperkalaemia is a growing concern in the treatment of patients with heart failure and reduced ejection fraction (HFrEF) as it limits the use of some prognostic-modifying drugs and has a negative impact on prognosis. The objective of the present study was to estimate the prevalence of hyperkalaemia in outpatients with HFrEF and its impact on achieving optimal medical treatment. For this purpose, a multicentre, prospective, and observational study was carried out on consecutive HFrEF patients who were monitored as outpatients in heart failure (HF) units and who, in the opinion of their doctor, received optimal medical treatment. A total of 565 HFrEF patients were included from 16 specialised HF units. The mean age was 66 ± 12 years, 78% were male, 45% had an ischemic cause, 39% had atrial fibrillation, 43% were diabetic, 42% had a glomerular filtration rate < 60 mL/min/1.7 m2, and the mean left ventricular ejection fraction was 31 ± 7%. Treatment at the study entry included: 76% on diuretics, 13% on ivabradine, 7% on digoxin, 18.9% on angiotensin-conversing enzyme inhibitors (ACEi), 11.3% on angiotensin receptors blockers (ARBs), 63.8% on angiotensin-neprilysin inhibitors (ARNi), 78.5% on mineralocorticoid receptor antagonists (MRAs), and 92.9% on beta-blockers. Potassium levels in the baseline analysis were: ≤5 mEq/L = 80.5%, 5.1−5.4 mEq/L = 13.8%, 5.5−5.9 mEq/L = 4.6%, and ≥6 mEq/L = 1.06%. Hyperkalaemia was the reason for not prescribing or reaching the target dose of an MRAs in 34.8% and 12.5% of patients, respectively. The impact of hyperkalaemia on not prescribing or dropping below the target dose in relation to ACEi, ARBs, and ARNi was significantly less. In conclusion, hyperkalaemia is a frequent problem in the management of patients with HFrEF and a limiting factor in the optimisation of medical treatment.

Abstract
AIMS Renin-angiotensin-aldosterone system inhibitors (RAASi) therapy is commonly used to reduce the risk of death and to slow down disease progression in patients with chronic kidney disease (CKD), heart failure (HF) and hypertension. However, the cardio-renal benefits of RAASi therapy are also associated with an increased risk of hyperkalemia (HK), which may lead to dose reduction or discontinuation of therapy. Patiromer has demonstrated to reduce the risk of HK, which enables to maintain optimal doses of RAASi therapy. This study aimed to assess the cost-effectiveness of patiromer for the management of HK in CKD patients with and without HF in Spain. METHODS A Markov model was developed to evaluate the costs and benefits of patiromer for the management of HK in patients with CKD stages 3-4 with and without HF treated with RAASi over a lifetime horizon. The main outcomes included total direct costs (€2021), quality-adjusted life-years (QALYs), life-years gained (LYG) and incremental cost-effectiveness ratio (ICER). Deterministic one-way and probabilistic sensitivity analyses were performed to assess the robustness of the results. RESULTS Patiromer was more effective compared to no patiromer (5.76 vs 5.57 QALYs; 7.73 vs 7.50 LYG), and resulted in an incremental cost of €3,574, yielding an ICER of €19,092/QALY gained and of €15,236/LYG. Sensitivity analyses suggested that the results were robust to changes in most input parameters. CONCLUSIONS Patiromer is a cost-effective intervention in maintaining normokalemia and enabling optimal RAASi therapy in patients with CKD stages 3-4 with and without HF in Spain.

Abstract
BACKGROUND Hyperkalaemia (HK) is a common electrolyte disorder in patients with chronic kidney disease (CKD) and/or treated with renin-angiotensin-aldosterone system inhibitors (RAASis). The aim of this study is to determine the severity, current management and cost of chronic HK. METHODS We performed a retrospective cohort study of patients with chronic HK and CKD, heart failure or diabetes mellitus between 2011 and 2018. The study follow-up was 36 months. RESULTS A total of 1499 patients with chronic HK were analysed: 66.2% presented with mild HK, 23.4% with moderate HK and 10.4% with severe HK. The severity was associated with CKD stage. Most patients (70.4%) were on RAASi therapies, which were frequently discontinued (discontinuation rate was 39.8, 49.8 and 51.8% in mild, moderate and severe HK, respectively). This RAASi discontinuation was similar with or without resin prescription. Overall, ion-exchange resins were prescribed to 42.5% of patients with HK and prescriptions were related to the severity of HK, being 90% for severe HK. Adherence to resin treatment was very low (36.8% in the first year and 17.5% in the third year) and potassium remained elevated in most patients with severe HK. The annual healthcare cost per patient with HK was €5929, reaching €12 705 in severe HK. Costs related to HK represent 31.9% of the annual cost per HK patient and 58.8% of the specialized care cost. CONCLUSIONS HK was usually managed by RAASi discontinuation and ion-exchange resin treatment. Most patients with HK were non-adherent to resins and those with severe HK remained with high potassium levels, despite bearing elevated healthcare expenditures.
