The Effects of SGLT2 Inhibitors on Lipid Profile and Kidney Function in Patients with Chronic Kidney Disease Regardless of Diabetes and Hypertension Status

Abstract

Background: Chronic kidney disease (CKD) is a progressive, irreversible impairment of kidney function due to various etiologies. Numerous studies have shown that sodium-glucose cotransporter-2 inhibitors (SGLT2i) slow the progression of CKD, due to their pleiotropic effects. Therefore, there has been an increase in interest in their effects not only on kidney function but also on other parameters in patients with CKD. The aim of the study was to examine the effects of SGLT2i on serum lipid values and kidney function in patients with CKD undergoing SGLT2i treatment. Methods: This study was a retrospective data analysis of 75 patients with CKD on SGLT2i treatment. We compared the values of biochemical parameters, renal function outcomes, and blood pressure at two time points: baseline and 24 months after. Results: Total cholesterol (Chol) significantly decreased in all patients, while triglyceride (Tg) and low-density lipoprotein cholesterol (LDLc) levels also decreased in all patients. High-density lipoprotein cholesterol (HDLc) levels increased, but this increase was not significant. Creatinine clearance (Ccr) significantly decreased, and serum urea (Sur) significantly increased in all patients. The proteinuria (Prt) levels did not change significantly. The results showed that the diastolic blood pressure (DBP) significantly decreased in all patients. Conclusions: This study showed that the use of SGLT2i reduced total Chol in all patients with CKD during the 24-month follow-up, regardless of diabetes mellitus (DM) status. No significant differences were observed for the Tg, LDLc, and HDLc values.
