The impact of sodium-glucose Cotransporter-2 inhibitors on lipid profile: A meta-analysis of 28 randomized controlled trials

Aim: The present study aimed to evaluate the impact of sodium-glucose cotransporter-2 inhibitors (SGLT2is) on blood lipid profile.

Methods: We searched the PubMed, Cochrane Library, Medline, and EMBASE databases from the inception to July 2023 for randomized controlled trials (RCTs) comparing SGLT2i with placebo regarding lipid profile changes. The "Meta" package of R software was applied for data synthesis.

Results: A total of 28 RCTs were included and 5192 patients participated in the present study, including 2686 patients who received SGLT2is intervention and 2506 patients who were in the control group. SGLT2is significantly increased blood low density lipoprotein cholesterol (LDL-C) levels [mean difference (MD): 0.09 mmol/L, 95% confidence interval (CI) (0.03, 0.16), 95% prediction interval (PI) (-0.06, 0.24), P = 0.0046] and high density lipoprotein cholesterol (HDL-C) levels [MD: 0.08 mmol/L, 95% CI (0.06, 0.11), 95% PI (-0.00, 0.17), P < 0.0001]. However, we observed neutral effect of SGLT2is on total cholesterol (TC) [MD: 0.08 mmol/L, 95% CI (-0.08, 0.24), 95% PI (-0.24, 0.40), P = 0.3150] and triglyceride (TG) [MD: -0.03 mmol/L, 95% CI (-0.23, 0.16), 95% PI (-0.70, 0.63), P = 0.7382].

Conclusion: Our study determined that SGLT2is increase both LDL-C and HDL-C levels, but exerts not significant effect on TC and TG levels.
