Management of Chronic Kidney Disease Grade IV with Diabetes

Pharmacological Therapy for Hyperglycemia

The American College of Physicians recommends that patients with CKD grade IV (eGFR 15-29 mL/min/1.73 m²) and diabetes be treated with SGLT2 inhibitors as first-line therapy, along with metformin (if eGFR ≥30), and long-acting GLP-1 receptor agonists if glycemic targets are not met, combined with renin-angiotensin system blockers for patients with albuminuria and hypertension 1, 2, 3
SGLT2 inhibitors are recommended for all patients with type 2 diabetes and CKD with eGFR ≥20 mL/min/1.73 m², providing substantial cardiovascular and renal protection regardless of glucose-lowering effect 1, 2, 4
The American Diabetes Association recommends that metformin be used as first-line therapy for patients with eGFR ≥30 mL/min/1.73 m², in combination with SGLT2 inhibitors 2, 5, 6
Long-acting GLP-1 receptor agonists are recommended if glycemic targets are not met with metformin and SGLT2 inhibitors, or if these medications cannot be used 1, 2, 5

The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend that ACE inhibitors or ARBs be started and titrated to the highest approved and tolerated dose in patients with diabetes, hypertension, and albuminuria 7
These therapies slow the progression of CKD in patients with diabetes 7

The American Diabetes Association recommends individualized HbA1c targets ranging from <6.5% to <8.0%, depending on the risk of hypoglycemia and comorbidities 3, 6
HbA1c remains the primary tool for monitoring glycemic control in CKD grade IV 6

The Academy of Nutrition and Dietetics recommends a diet high in vegetables, fruits, whole grains, fiber, legumes, plant-based protein, unsaturated fats, and nuts, and low in processed meats, refined carbohydrates, and sugary drinks 3, 6
The World Health Organization recommends a daily protein intake of 0.8 g/kg body weight 2, 3
The American Heart Association recommends limiting sodium intake to <2 g/day (or <5 g sodium chloride/day) 2, 3, 5, 6
The American College of Sports Medicine recommends at least 150 minutes of moderate-intensity physical activity per week, adjusted according to cardiovascular and physical tolerance 2, 3, 5, 6

The American College of Cardiology recommends statin therapy for all patients with diabetes and CKD: moderate-intensity for primary prevention of ASCVD or high-intensity for patients with known ASCVD 4
Blood pressure control is a critical component of a comprehensive strategy to reduce the risk of kidney disease progression and cardiovascular disease 7, 8

The American Diabetes Association recommends structured diabetes self-management education programs to empower patients to develop knowledge and self-management skills 1, 3
Programs can be delivered in person as one-on-one or group-based programs or through technology platforms 1
The best approach is tailored to individual preferences and learning styles 1
