Abstract

Chronic kidney disease constitutes a major microvascular complication of diabetes mellitus. Accumulating data suggest that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) might have a role in the management of diabetic kidney disease (DKD). GLP-1 RAs appear to reduce the incidence of persistent macro-albuminuria in patients with type 2 diabetes mellitus. This beneficial effect appears to be mediated not only by the glucose-lowering action of these agents but also on their blood pressure lowering, anti-inflammatory and antioxidant effects. On the other hand, GLP-1 RAs do not appear to affect the rate of decline of glomerular filtration rate. However, this might be due to the relatively short duration of the trials that evaluated their effects on DKD. Moreover, these trials were not designed nor powered to assess renal outcomes. Given than macrolbuminuria is a strong risk factor for the progression of DKD, it might be expected that GLP-1 RAs will prevent the deterioration in renal function in the long term. Nevertheless, this remains to be shown in appropriately designed randomized controlled trials in patients with DKD.

Core Tip: Glucagon-like peptide-1 receptor agonists prevent the development of persistent macroalbuminuria in patients with type 2 diabetes mellitus. However, it is unclear whether they delay the decline in glomerular filtration rate in this population. Long-term trials are needed to clarify the role of these agents in the management of diabetic nephropathy.
