What are reasons to hold ACE inhibitors or ARBs?
How does hypertension lead to CKD?
Increased intraglomerular pressure damages the glomerulus, leading to decreased GFR over time.
How does hypertension affect the heart in CKD patients?
It increases heart workload and can cause left ventricular hypertrophy (LVH)
When are ACE inhibitors or ARBs especially indicated in CKD?
In patients with albuminuria
Who should get SGLT2 inhibitors?
Patients with:
* Type 2 diabetes + CKD
* AND eGFR >20
What is the primary benefit of SGLT2 inhibitors in CKD?
They slow progression of CKD by reducing intraglomerular pressure.
Where do SGLT2 inhibitors act in the nephron?
Proximal tubule
Can SGLT2 inhibitors be used in CKD patients without diabetes?
Yes, especially if albuminuria or heart failure is present
What level of albuminuria supports SGLT2 inhibitor use?
Urine ACR >200 mg/g
Should SGLT2 inhibitors be used in CKD patients with heart failure?
Yes, regardless of albuminuria
When should SGLT2 inhibitors be continued until?
Until dialysis or kidney transplant is initiated
When should SGLT2 inhibitors be temporarily held?
During prolonged fasting, surgery, or critical illness
What MRA is commonly used in CKD progression?
Finerenone
Which patients are candidates for finerenone?
CKD with type 2 diabetes, albuminuria >30 mg/g, on ACEi/ARB, with normal potassium
What is the major adverse effect of finerenone?
Hyperkalemia
What must be monitored when using finerenone?
Potassium levels
When should GLP-1 receptor agonists be used in CKD?
When glycemic targets are not met despite metformin and SGLT2 inhibitor use
What is the stepwise therapy for CKD progression?
ACEi/ARB → SGLT2 inhibitor → Finerenone → GLP-1 receptor agonist
When are calcium channel blockers used in CKD?
As add-on therapy when blood pressure is not controlled with ACEi/ARB
Which diuretics are preferred in early CKD (eGFR >30)?
Thiazide diuretics
Which diuretics are preferred in advanced CKD (eGFR <30)?
Loop diuretics
What is the main risk of steroidal MRAs in CKD?
Hyperkalemia
How does finerenone differ from spironolactone?
It is more selective, has lower hyperkalemia risk, and provides kidney protection.
What is recommended for patients ≥50 with CKD and eGFR <60?
Statin or statin + ezetimibe
