What is the best therapy to reverse Chronic Kidney Disease (CKD)?

Best Therapies for Chronic Kidney Disease Management

The most effective approach to manage chronic kidney disease (CKD) is a combination of renin-angiotensin system inhibitors (ACE inhibitors or ARBs) and SGLT2 inhibitors, which have been shown to slow progression and in some cases reverse early kidney damage. 1

First-Line Pharmacological Therapies

Renin-Angiotensin System Inhibitors

• ACE inhibitors or ARBs are recommended as first-line therapy for patients with CKD, particularly those with albuminuria >30 mg/24 hours 1
• These medications should be titrated to the highest approved dose that is tolerated to maximize kidney protection 1
• RAS inhibitors slow progression of kidney disease in persons with albuminuria and hypertension independent of their effects on blood pressure 1
• Sustained reduction in urine protein excretion is a critical treatment goal and marker of therapeutic success 1

SGLT2 Inhibitors

• Recent guidelines recommend SGLT2 inhibitors alongside RAS inhibitors as foundational therapy for CKD management 2
• SGLT2 inhibitors prevent CKD progression and reduce fatal and non-fatal kidney events, hospitalization for heart failure, and all-cause mortality 2
• These medications have shown benefit in patients with and without type 2 diabetes 2

Blood Pressure Management

• For CKD patients with urine albumin excretion <30 mg/24 hours, target blood pressure should be ≤140/90 mmHg 1
• For CKD patients with urine albumin excretion ≥30 mg/24 hours, a more intensive target of ≤130/80 mmHg is recommended 1, 3
• Blood pressure control is critical in preventing CKD progression, breaking the vicious cycle between hypertension and kidney damage 1

Metabolic Management

Glycemic Control

• For patients with diabetic kidney disease, target HbA1c of approximately 7.0% is recommended to slow CKD progression 4
• Intensive glucose control reduces the risk of microalbuminuria and macroalbuminuria 3

Lipid Management

• For adults ≥50 years with eGFR <60 ml/min/1.73 m², statin or statin/ezetimibe combination therapy is recommended 1
• For adults ≥50 years with CKD and eGFR ≥60 ml/min/1.73 m², statin therapy is recommended 1
• Lipid management reduces cardiovascular risk, which is particularly elevated in CKD patients 1

Lifestyle Interventions

• Reduced sodium intake to <2 g per day 1
• Weight loss to achieve a healthy BMI of 20-25 kg/m² 1
• Regular physical activity (30 minutes of exercise 5 times per week) 1, 3
• Smoking cessation 1
• Mediterranean-style diet may help reduce cardiovascular risk and slow CKD progression 1, 3
• Limiting alcohol, meats, and high-fructose corn syrup intake 1

Emerging Therapies

• Mineralocorticoid receptor antagonists like finerenone have shown promise in reducing CKD progression 1, 4
• Endothelin receptor antagonists such as atrasentan may decrease the risk of renal events in diabetic CKD patients 3
• Pentoxifylline has shown some benefit in managing CKD 3

Monitoring and Evaluation

• Regular monitoring of estimated GFR and urine albumin-creatinine ratio is essential 2
• Reduction in albuminuria is a key marker of treatment success and should be targeted specifically 1
• CKD regression can be defined as a sustained increase in GFR by ≥25% and improvement in GFR category 5
• CKD remission is defined as achieving GFR ≥60 ml/min/1.73m² and urine albumin-creatinine ratio <30 mg/g 5

Common Pitfalls to Avoid

• Underutilization of proven therapies: Only 25-40% of eligible CKD patients receive RAS inhibitors despite clear benefits 1
• Inadequate dose titration: RAS inhibitors should be titrated to the maximum tolerated dose for optimal benefit 1
• Discontinuing RAS inhibitors prematurely: These medications can be continued unless creatinine increases by more than 30% 1
• Combination of ACE inhibitors and ARBs: This combination is harmful and should be avoided 1
• Neglecting non-pharmacological interventions: Lifestyle modifications are essential components of CKD management 1
• Avoiding NSAID use: For patients with CKD and gout, low-dose colchicine or glucocorticoids are preferable to NSAIDs 1

By implementing this comprehensive approach focusing on RAS inhibition, SGLT2 inhibition, blood pressure control, and lifestyle modifications, CKD progression can be significantly slowed and, in some cases, early kidney damage may be reversed.
