Comprehensive Management of Chronic Kidney Disease

Introduction to CKD Management

The management of chronic kidney disease requires a comprehensive treatment strategy targeting blood pressure control, cardiovascular risk reduction, lifestyle modifications, and monitoring for complications to reduce the risk of disease progression and associated morbidity and mortality, as recommended by the Kidney International guidelines 1, 2

Use validated risk prediction tools to guide management decisions, with a 2-year kidney failure risk threshold of >10% determining timing for multidisciplinary care and >40% for kidney replacement therapy preparation, according to Kidney International 2, 3
For cardiovascular risk prediction, use externally validated models that incorporate eGFR and albuminuria to guide preventive therapies, as suggested by Kidney International 2, 3

In CKD patients without albuminuria, target blood pressure should be <140/90 mmHg, as recommended by Kidney International 4, 5
In patients with albuminuria ≥30 mg/24h, aim for a lower target of <130/80 mmHg, according to Kidney International 4, 5
Use angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) as first-line therapy, especially in patients with albuminuria, as recommended by Kidney International 4, 6
Titrate ACEi or ARBs to the highest approved dose that is tolerated to maximize kidney protection, as suggested by Kidney International 6

Prescribe statins or statin/ezetimib combination for adults ≥50 years with eGFR <60 ml/min/1.73 m² (CKD G3a-G5), as recommended by the American College of Cardiology, based on information from Praxis Medical Insights 7
Choose statin-based therapies that maximize absolute reduction of LDL-cholesterol, according to the American Heart Association, based on information from Praxis Medical Insights 7
Recommend a plant-based "Mediterranean" diet in addition to lipid-lowering therapy, as suggested by the American Heart Association, based on information from Praxis Medical Insights 7

Recommend moderate-intensity physical activity for at least 150 minutes per week, adjusted to cardiovascular and physical tolerance, as recommended by the World Health Organization, based on information from Kidney International 1, 8, 9
Advise patients to avoid sedentary behavior, as recommended by the World Health Organization, based on information from Kidney International 1, 8, 9
Encourage weight loss for patients with obesity and CKD, as suggested by the National Institutes of Health, based on information from Kidney International 1, 8, 9
Promote smoking cessation, as recommended by the Centers for Disease Control and Prevention, based on information from Kidney International 1
Advise adoption of healthy, diverse diets with higher consumption of plant-based foods and lower consumption of ultra-processed foods, as recommended by the Academy of Nutrition and Dietetics, based on information from Kidney International 1, 8, 9

Maintain protein intake at 0.8 g/kg body weight/day in adults with CKD G3-G5, as recommended by the National Kidney Foundation, based on information from Kidney International 1, 8
Avoid high protein intake (>1.3 g/kg body weight/day) in adults with CKD at risk of progression, as suggested by the National Kidney Foundation, based on information from Kidney International 1, 8
For patients at high risk of kidney failure who are willing and able, consider a very low-protein diet (0.3-0.4 g/kg body weight/day) with essential amino acid or ketoacid analog supplementation under close supervision, as recommended by the National Kidney Foundation, based on information from Kidney International 1, 8
Limit foods with high potassium content in patients with history of hyperkalemia, as suggested by the American Heart Association, based on information from Praxis Medical Insights 7

Treat symptomatic hyperuricemia (gout) with urate-lowering therapy, preferring xanthine oxidase inhibitors over uricosuric agents, as recommended by the American College of Rheumatology, based on information from Praxis Medical Insights 7
Do not prescribe urate-lowering therapy for asymptomatic hyperuricemia to delay CKD progression, as suggested by the American College of Rheumatology, based on information from Praxis Medical Insights 7
Recommend non-pharmacological measures for gout prevention (limiting alcohol, meat, and high-fructose corn syrup), as recommended by the American College of Rheumatology, based on information from Praxis Medical Insights 7
Provide pharmacological treatment with or without dietary intervention to prevent acidosis (serum bicarbonate <18 mmol/L), as suggested by the National Kidney Foundation, based on information from Praxis Medical Insights 7
Monitor treatment to ensure serum bicarbonate doesn't exceed normal limits and doesn't negatively impact blood pressure, serum potassium, or fluid balance, as recommended by the National Kidney Foundation, based on information from Praxis Medical Insights 7

Adjust medication dosages according to kidney function, as recommended by the National Kidney Foundation, based on information from Praxis Medical Insights 7
For patients with atrial fibrillation, prefer non-vitamin K antagonist oral anticoagulants (NOACs) over vitamin K antagonists, with appropriate dose adjustments based on GFR, as suggested by the American Heart Association, based on information from Praxis Medical Insights 7

For children with CKD, encourage physical activity aiming for WHO-advised levels (≥60 minutes daily) and achievement of healthy weight, as recommended by the World Health Organization, based on information from Kidney International 1, 8, 9
Do not restrict protein intake in children with CKD due to risk of growth impairment, as suggested by the National Kidney Foundation, based on information from Kidney International 8
