Blood pressure effects of SGLT2 inhibitors in kidney transplant recipients: a systematic review and meta-analysis
Abstract
Background: Post-transplant hypertension is common in kidney transplant recipients and contributes to cardiovascular risk and allograft dysfunction. Most available data come from studies where the primary indication for SGLT2 inhibitor use was post-transplant diabetes mellitus or cardiorenal protection, with blood pressure assessed as a secondary outcome.
Objectives: To systematically evaluate the impact of SGLT2 inhibitors on blood pressure, metabolic and renal outcomes, and safety in kidney transplant recipients.
Methods: PubMed, Embase, and Scopus clinical trial registries were systematically searched from inception to October 20, 2025. Randomized controlled trials and observational studies were included. Primary outcomes were changes in systolic and diastolic blood pressure at 3, 6, and 12 months. Secondary outcomes included body weight, glycated hemoglobin (HbA1c), renal function, and adverse events.
Results: Twelve studies comprising 1,292 participants were included. In controlled difference-in-differences analyses (5 studies), SGLT2 inhibitors showed no significant blood pressure reductions versus control at any time point. Exploratory single-arm analyses suggested within-group systolic blood pressure reductions at 3 and 6 months; however, these estimates are at high risk of bias and cannot establish treatment effect.
Conclusion: Exploratory single-arm analyses suggested modest short-term reductions in systolic blood pressure and suggested metabolic effects with an…
