Abstract:
Sodium glucose cotransporter 2 (SGLT2) inhibitors are a class of glucose-lowering agents widely used for the treatment of type 2 diabetes mellitus. A number of clinical trials in type 2 diabetic patients with different degrees of renal impairment have clearly demonstrated that SGLT2 inhibitors reduce the progression rate of diabetic kidney disease. Furthermore, recent studies have shown that SGLT2 inhibitors also exert a protective effect in the case of non-diabetic kidney disease. Consequently, it has been hypothesized that the nephroprotective activity of these drugs could exceed the canonical impact on glycemic control and that the resulting beneficial effects could be the consequence of their pleiotropic properties (proven reduction of inflammation, fibrosis, oxidative stress and sympathetic nervous activity) both at systemic and tissue levels, suggesting that the efficacy of these drugs could also be extended to non-diabetic nephropathies. This review focuses on the nephroprotective effects of SGLT2 inhibitors in different experimental models of non-diabetic kidney disease. The different glucose-independent mechanisms potentially implemented by SGLT2 inhibitors to ultimately protect the non-diabetic kidney are described in detail, and conflicting results, when present, are discussed.
Insights
Sodium glucose cotransporter 2 (SGLT2) inhibitors show promise for kidney protection beyond diabetes. These drugs may offer benefits in non-diabetic kidney diseases by reducing inflammation and fibrosis.
Area of Science:
- Nephrology
- Pharmacology
Background:
- Sodium glucose cotransporter 2 (SGLT2) inhibitors are established treatments for type 2 diabetes.
- Clinical trials show SGLT2 inhibitors slow diabetic kidney disease progression.
Purpose of the Study:
- To review the nephroprotective effects of SGLT2 inhibitors in non-diabetic kidney disease models.
- To explore glucose-independent mechanisms of SGLT2 inhibitor action in kidney protection.
Main Methods:
- Review of experimental studies on SGLT2 inhibitors in non-diabetic kidney disease.
- Detailed analysis of proposed glucose-independent mechanisms.
Main Results:
- SGLT2 inhibitors demonstrate protective effects in various non-diabetic kidney disease models.
- Evidence suggests pleiotropic actions including reduced inflammation, fibrosis, oxidative stress, and sympathetic activity.
Conclusions:
- SGLT2 inhibitors possess nephroprotective properties applicable to non-diabetic kidney diseases.
- Glucose-independent mechanisms contribute significantly to the renal benefits of SGLT2 inhibitors.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
