Background: The effects of sodium-glucose cotransporter-2 inhibitors (SGLT2i) on renal outcomes in patients with varying combinations of heart failure (HF), chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) remains unclear.

Methods: Online databases were queried up to May 2023 for primary and secondary analysis of trials of SGLT2i in patients with HF, CKD, or T2DM. Outcomes of interest were composite renal endpoint (defined as an eGFR <15 mL/min/1.73 m2, doubling of serum creatinine, some percent change in eGFR, and/or need for kidney replacement therapy) and change in estimated glomerular filtration rate (eGFR) slope. Hazard ratios (HR) and mean difference with their 95% confidence intervals were pooled using the generic inverse variance method and a random-effects model.

Results: 10 trials (n=70,117 patients) were included. Compared with placebo, SGLT2i reduced the risk of composite renal endpoint by 35% in HF (HR: 0.65; 95% CI: 0.50-0.84), 38% in CKD (HR: 0.62; 95% CI: 0.54-0.71), and 37% in DM (HR:0.63; 95% CI: 0.54, 0.73). A similar pattern of benefit was observed in different combinations of these diseases ( Figure 1 ), as well as patients without baseline HF (HR:0.57; 95% CI: 0.51, 0.63), CKD (HR:0.64; 95% CI: 0.42, 0.98) and T2DM (HR:0.62; 95% CI: 0.45, 0.86). Findings were similar for change in eGFR slope.

Conclusions: SGLT2i improve renal outcomes in cohorts of HF, CKD and T2DM and these effects appear consistent across patients with different combinations of these conditions.
