A New Era in Diabetic Kidney Disease Treatment: The Four Pillars and Strategies to Build Beyond.

Diabetic kidney disease (DKD) is a prevalent and complex disease among patients with diabetes in Korea, requiring comprehensive treatment strategies. Traditional management strategies targeting blood pressure, blood sugar, lipid, and lifestyles are foundational approaches of DKD treatment, each of them still holding importance in current paradigms. The four pillars, renin-angiotensin system(RAS) inhibitors, sodium-glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and non-steroidal mineralocorticoid receptor antagonists (nsMRA) can enhance DKD treatment. Expanding beyond these pillars with future-oriented pillars including precision medicine, digital health, gut health, anti-inflammatory/fibrotic agents, psychosocial/behavioral health, and regenerative medicine can further advance DKD treatment strategies, offering a more cohesive framework which shifts a disease-centered approach to a patient-centered approach.
