- Abstract
Sodium-glucose cotransporter 2 inhibitors are antihyperglycaemic medications with an emerging evidence base for cardiovascular and kidney disease risk reduction. Sodium-glucose cotransporter 2 inhibitors medications lower plasma glucose by inhibiting glucose reabsorption in the proximal tubule of the kidney independent of insulin. Furthermore, they reduce intraglomerular pressure by restoring tubuloglomerular feedback. Large cardiovascular outcome trials of both empagliflozin and canagliflozin have consistently shown beneficial kidney effects that go beyond glycaemic control, such as reducing risk for incident nephropathy and progression of chronic kidney disease. The mechanisms by which sodium-glucose cotransporter 2 inhibitors improve kidney outcomes are not clear. Proposed hypotheses underpinning the kidney benefits include kidney-specific effects such as decreased intraglomerular pressure, activation of angiotensin-(l-7) and the Mas receptor leading to decreased inflammation, decrease in overall kidney oxygen consumption, rise in erythropoietin levels, inhibition of the renal sodium-hydrogen exchanger and secondary kidney effects related to improvements in HbAlc and blood pressure. This review will focus on describing the mechanisms of action of sodium-glucose cotransporter 2 inhibitors in the kidney, clinical efficacy data on their use in patients with chronic kidney disease, postulated physiologic underpinnings of kidney protection observed with sodium-glucose cotransporter 2 inhibitors and the promise and potential pitfalls for their use in patients with chronic kidney disease.
