Abstract
Background and Aims
Hyperkalemia (HK) is a potentially life-threatening condition, in patients with chronic kidney disease (CKD) and congestive heart failure (CHF).
The majority of patients affected with CKD or CHF, must be treated with inhibitors of renin angiotensin aldosterone system (RAASi) and mineralocorticoid receptor antagonists (MRAs). However, the treatments previously mentioned, increase the risk of HK episodes, which is the main cause of RAASi and MRAs downtitration or discontinuation, representing an undesirable clinical scenario, given that the patients are at high risk of be deprived of their nephroprotective effect and cardio-renal benefits
The aim of the study is: to analyze if, in patients with HK, CKD and CHF treated with RAASi and/or MRA, serum potassium (sK) reduction by Sodium zirconium cyclosilicate (SZC) treatment is non-inferior to RAASi and/or MRAs discontinuation or downtitration.
Method
Results
The study will demonstrate results on serum electrolytes, renal function, albuminuria, KDQoL questionnaire and changes in relative overhydration (multifrequency bioimpedance -BCM Fresenius-)
Conclusion
The KEEP ON study will define the ability of SZC to facilitate the use of RAAS-I and / or MRA in patients with HK and cardiorenal syndrome allowing the maintenance of the medications recommended by international guidelines for the treatment of CHF at different degrees of CKD while maintaining the potential cardio-renal and nephroprotective benefit.
