Healthy Diet Rich in Potassium to Chronic Kidney Disease With Sodium Zirconium Cyclosilicate: A Feasibility Study

During 3 weeks, SZC will be prescribed to normalize plasma potassium to 3.5 to 5.0 mml/L, and a diet with energy 25-35 kcal/kg/day and protein 0.6 to 0.8 g/kg/day and with low K content will be prescribed. At the end of the first 3 weeks, the patients will initiate a healthy diet containing 3700 to 4000 mg/potassium for 3 weeks (healthy diet phase). A food basket containing fruits, vegetables, whole grains, nuts, white meat, fish and eggs in amounts adequate for the patient will be provided. Serum K will be monitored to promote serum K between 3.5 to 5.0 mmol/L and adjustments in the dose of SZC will be performed according to the drug label. During stabilization and healthy diet phases, serum K will be measured every 72 hours until serum K is normalized and after that, once per week.
