For almost two decades, the management of patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) was based on the optimal glycemic and blood pressure control as well as on the adequate blockade of the renin-angiotensin-system. Over the past few years, sodium-glucose co-transporter 2 (SGLT-2) inhibitors and glucagone-like peptide 1 receptor agonists (GLP1-RAs) were added to our therapeutic armarhatum, offering promise for more effective mitigation of the substantial residual cardiorenal risk of these patients. Large randomized controlled trials (RCTs) designed to demonstrate the cardiovascular safety of SGLT-2 inhibitors and GLP1-RAs showed that these novel anti-diabetic medications improve cardiovascular outcomes in patients with T2DM. RCTs conducted specifically in CKD patients with or without T2DM demonstrated that SGLT-2 inhibitors were also effective in retarding the progression of kidney injury to end-stage kidney disease. The kidney protective effects of GLP1-RA are not yet proven, but RCTs are currently ongoing to investigate this crucial research question. In this article, we review the available clinical-trial evidence supporting the use of SGLT-2 inhibitors and GLP1-RAs for cardiorenal protection in patients with T2DM and CKD. We provide clinical practice recommendations for a personalized approach in the use of these novel therapies, according to the severity of CKD and the presence of other cardiometabolic risk factors.
