[Semaglutide in Chronic Kidney Disease: Great Enthusiasm. But How Does It Work?]

Abstract

Chronic Kidney Disease (CKD) is a clinical condition characterized by the progressive loss of kidney function. 10% of the world's population is affected by this condition, which represents the fifth leading cause of death globally. Furthermore, CKD is associated with increased risk of fatal and non-fatal cardiovascular events, and progression to end-stage renal disease. Over the last twenty years, an exponential growth in its prevalence and incidence has been observed. For this reason, various drugs have been developed and implemented in clinical practice, with various mechanisms, with the aim of reducing and minimizing this dramatic "cardio-renal" risk. These include SGLT2 inhibitors, mineralocorticoid receptor antagonists, and endothelin receptor antagonists. However, a large proportion of CKD patients do not respond sufficiently to these treatments. GLP-1 receptor agonists represent a class of antidiabetic and nephroprotective drugs that are very promising in improving the prognosis of patients with CKD, especially if associated with one of the above-mentioned classes. In this article, we discuss the direct and indirect mechanisms through which one of the GLP-1 agonists, semaglutide, ensures nephro- and cardioprotection in patients with CKD and type 2 diabetes.
