Abstract
There are no relevant meta-analyses that have assessed the safety of the sodium-glucose transporter 2 (SGLT2) inhibitors in different chronic diseases. We aimed at evaluating the safety of four SGLT2 inhibitors in three chronic diseases by meta-analysis of the large randomized trials of SGLT2 inhibitors. We performed random-effects meta-analysis and carried out subgroup analysis according to type of underlying diseases and type of SGLT2 inhibitors. SGLT2 inhibitors versus placebo significantly reduced the risk of acute kidney injury (RR 0.75, 95% CI 0.66–0.85), and showed the reduced trend in the risk of severe hypoglycemia (RR 0.86, 95% CI 0.71–1.03). SGLT2 inhibitors significantly increased the risks of diabetic ketoacidosis (RR 2.57), genital infection (RR 3.75), and volume depletion (RR 1.14); and showed the increased trends in the risks of fracture (RR 1.07), amputation (RR 1.21), and urinary tract infection (RR 1.07). These effects exhibited by SGLT2 inhibitors were consistent across three chronic diseases (i.e. type 2 diabetes, chronic heart failure, and chronic kidney disease) and four SGLT2 inhibitors (i.e. dapagliflozin, empagliflozin, ertugliflozin, and canagliflozin) (all Psubgroup > 0.05). These findings will guide that specific adverse events are monitored when SGLT2 inhibitors are used in clinical practice.
