Glucagon and glucagon-like peptide-1 dual agonist therapy: A possible future towards fatty kidney disease.

Abstract

Background: Obesity is a growing epidemic affecting approximately 40% of the adult population in developed countries with major health consequences and comorbidities, including diabetes mellitus and insulin resistance, metabolically associated fatty liver disease, atherosclerotic cardiovascular and cerebrovascular diseases and chronic kidney disease. Pharmacotherapies targeting significant weight reduction may have beneficial effects on such comorbidities, though such therapeutic options are highly limited. In this narrative review, we aim to evaluate current knowledge regarding dual agonist therapies and potential implications for managing fatty kidney and chronic kidney disease.

Results and conclusion: Glucagon-like peptide-1 agonists and sodium-glucose cotransporter-2 inhibitors are two novel classes of glucose-lowering medications with potential implications and beneficiary effects on renal outcomes, including estimated glomerular filtration rate, albuminuria and chronic kidney disease progression. Recently, dual agonist therapies targeting glucagon-like peptide-1 and glucagon receptors, namely survodutide and cotadutide, have been evaluated in managing metabolically associated fatty liver disease, a well-established example of visceral obesity. Fatty kidney is another novel concept implicated in the pathophysiology of chronic kidney disease among patients with visceral obesity.
