The Rest is Kidneys podcast series is brought to you by Imperial College Healthcare NHS Trust and North West London Integrated Care Board (NWL NHS)

In this episode, Jeremy Levy and Andrew Frankel discuss the role of renin-angiotensin-aldosterone system inhibitors (RAASi) in the management of chronic kidney disease (CKD), looking deeper into the mechanisms, benefits and practical considerations of using RAASi.

They cover when to initiate these medications, the importance of maximum dosing, monitoring kidney function, and managing side effects like changes in GFR and potassium levels.

Key Takeaways:

1. RAASi Benefits Beyond Blood Pressure:
   • These drugs lower blood pressure, slow CKD progression, and provide cardiovascular protection through mechanisms independent of blood pressure control.
   • Maximum dosing is essential for optimal kidney and heart protection.
2. Monitoring and Managing GFR Changes:
   • A GFR drop of up to 25% after starting RAASi is not a cause for concern.
   • Clinicians should reassure patients and recheck levels to ensure stability.
3. Potassium Management:
   • Mild to moderate increases in potassium (up to 6 mmol/L) are common and generally not an emergency.
   • Careful monitoring, addressing potential contributing factors, and avoiding unnecessary panic are key.

This episode provides practical insights and actionable advice for clinicians managing CKD patients.
