Background:
Sodium-glucose cotransporter 2 inhibitor (SGLT2i) blocks reabsorption of glucose by inhibiting SGLT2 in kidney, promotes the renal excretion of glucose and improves blood glucose control without requiring insulin secretion. Anti-atherosclerotic effects of SGLT2is have not been fully elucidated until today.
Methods:
We retrospectively picked up patients with type 2 diabetes who had been continuously prescribed SGLT2i for 3 months or more between April 2014 and December 2016 by a chart-based analysis, and compared metabolic parameters including coronary risk factors before the SGLT2i treatment with the data at 3 and 6 months after the SGLT2i treatment started.
Results:
We found 26 patients treated with tofogliflozin, 34 patients with canagliflozin, 27 patients with empagliflozin, 23 patients with ipragliflozin, 68 patients with dapagliflozin and 71 patients with luseogliflozin. Each SGLT2i ameliorated metabolic parameters, in different patterns. SGLT2is reduced body weight, systolic and diastolic blood pressures, plasma glucose, hemoglobin A1c, aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, uric acid, triglyceride and non-high-density lipoprotein-cholesterol (HDL-C), and elevated HDL-C; however, they did not affect LDL-cholesterol levels. Change in each metabolic parameter was significantly correlated with each metabolic parameter at baseline.
Conclusion:
The present study demonstrated that SGLT2i ameliorated body weight, blood pressure, liver function, serum lipids and uric acid, in addition to improvement of glucose metabolism in patients with type 2 diabetes.
Insights
Sodium-glucose cotransporter 2 inhibitors (SGLT2i) improve glucose control in type 2 diabetes. This study shows SGLT2 inhibitors also benefit weight, blood pressure, liver function, and lipid profiles.
Area of Science:
- Cardiology
- Endocrinology
- Metabolic Syndrome
Background:
- Sodium-glucose cotransporter 2 inhibitors (SGLT2i) promote glucose excretion, improving glycemic control in type 2 diabetes without insulin.
- The anti-atherosclerotic effects of SGLT2 inhibitors are not fully understood.
Purpose of the Study:
- To investigate the effects of SGLT2 inhibitors on metabolic parameters and coronary risk factors in patients with type 2 diabetes.
Main Methods:
- Retrospective chart analysis of type 2 diabetes patients treated with SGLT2 inhibitors for at least 3 months.
- Comparison of metabolic parameters and coronary risk factors before and 3-6 months after SGLT2 inhibitor initiation.
Main Results:
- All studied SGLT2 inhibitors (tofogliflozin, canagliflozin, empagliflozin, ipragliflozin, dapagliflozin, luseogliflozin) reduced body weight, blood pressure, glucose, HbA1c, liver enzymes, uric acid, triglycerides, and non-HDL-C.
- HDL-C levels were elevated by SGLT2 inhibitors.
- LDL-cholesterol levels remained unaffected.
Conclusions:
- SGLT2 inhibitors improve glucose metabolism, body weight, blood pressure, liver function, serum lipids, and uric acid in type 2 diabetes patients.
- These findings suggest broader benefits of SGLT2 inhibitors beyond glycemic control.

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:
Oral Hypoglycemic Agents: Biguanides and Glitazones
Secondary Active Transport
Secondary Active Transport
Glucose Absorption Into the Small Intestine
Dipeptidyl Peptidase 4 Inhibitors
