Abstract

BACKGROUND AND AIM: Sodium-glucose cotransporter (SGLT)-2 inhibitors are novel anti-diabetic medications with potential beneficial effects on cardiovascular and renal outcomes, metabolic parameters, and body weight. In addition to the beneficial effects on renal functions, including estimated glomerular filtration rate and reduction in proteinuria, recent studies have investigated the potential role of SGLT-2 inhibitor therapy on nephrolithiasis development. Nephrolithiasis, a condition affecting almost 10% of the general population at least once during a lifetime, is a common disorder with considerable risk for acute and chronic kidney injury and relatively few effective therapeutic options.

MATERIALS AND METHODS: We have performed a literature search through multiple databases, including PubMed, Ovid/Medline, Web of Science, Scopus, and Cochrane Library. We have followed the systematic review and meta-analysis guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses.We have included a total of 11 635 698 patients who experienced nephrolithiasis from six clinical trials to conduct this meta-analysis study. In the pooled analysis, nephrolithiasis occurred in 1,27% of patients from the SGLT2i group (n = 739 197), compared to 1,56% of patients (n = 10 896 501) from the control arm (active control, placebo or no therapy).

RESULTS: We have included a total of 11 635 698 participants who experienced nephrolithiasis from a total of six clinical studies with nephrolithiasis rates of 1,27% in the SGLT2i group (n = 739 197), compared to 1,56% in the control arm (n = 10 896 501). SGLT-2 inhibitor therapy has been associated with a lower risk for nephrolithiasis compared to placebo (OR 0.61, 95% CI, 0.53-0.70, p < 0.00001) or active therapy such as glucagon-like peptide 1 and dipeptidyl peptidase-IV inhibitors (OR 0.66, 95% CI, 0.47-0.93, p = 0.02).

CONCLUSION: We have demonstrated a lower risk of nephrolithiasis risk with SGLT-2 inhibitor therapy compared to placebo or active control. Potential underlying mechanisms include osmotic diuresis leading to a reduction in the concentration of lithogenic substances, anti-inflammatory and anti-fibrotic effects, and an increase in urine pH. There is a clear need for future large-scale randomized clinical trials evaluating such associations for better understanding.
