Diabetic kidney disease is a frequent and costly complication to type 2 diabetes. After many years with a lack of successful trials there are now significant developments that will change treatment, guidelines and future outcome. Since the last two decades blockade of the renin-angiotensin system (RAS) is standard treatment, but new antidiabetic treatments have shown potential for kidney protection. After cardiovascular outcome studies with glucagon-like peptide (GLP-1) receptor agonists it is evident that drugs like liraglutide, semaglutide and dulaglutide can reduce albuminuria levels and progression to macroalbuminuria. At present, a renal outcome trial with semaglutide is ongoing which will provide more evidence on the drug class in the future. The sodium glucose co-transporter 2 (SGLT2) inhibitor class has also demonstrated effects beyond glucose-lowering, as the drugs can reduce blood pressure, albuminuria and loss of renal function. In the first renal outcome study the SGLT2 inhibitor canagliflozin was found to reduce the risk of hard renal outcome with 30%. SGLT2 inhibition is now recommended in type 2 diabetes with chronic kidney disease. Renal outcome studies testing additional SGLT2 inhibitors and the GLP-1 receptor agonist semaglutide will report in the coming future potentially providing more and much needed options for treatment.
