This review discusses the current landscape of treatment options for DKD, including an RAAS blockade with ACE-I or ARB, and newer therapies such as sodium-glucose transport protein 2 (SGLT2) inhibitors, endothelin antagonists, glucagon-like peptide-1 (GLP-1) agonists, and mineralocorticoid receptor antagonists (MRA), along with a summary of landmark trials that support the use of these agents (Figure 1). This evidence concerns the gene SLC5A2 and diabetic kidney disease.
