Clinical trials with sodium-glucose cotransporter 2 (SGLT2) inhibitors (empagliflozin, dapagliflozin, and canagliflozin) have shown a decrease in the progression of chronic kidney disease (CKD). SGLT2 inhibitors represent a new category of oral antidiabetic agents that can also reduce systolic and diastolic blood pressure, as well as serum uric acid, and improve the glomerular filtration rate. Apart from affecting renal hemodynamics and glycotoxicity, evidence suggests that SGLT2 inhibitors may be renoprotective due to their effects on inflammation in renal tissues. Inflammatory responses play a prominent role in the pathophysiology of CKD as several structural and functional disorders of renal failure are strongly related to the overproduction of proinflammatory mediators. The present review discusses the anti-inflammatory properties of SGLT2 inhibitors. The different molecular pathways through which SGLT2 inhibitors may affect inflammation in the kidneys are also commented upon.
