ABSTRACT
Background
The efficacy and safety of the combination therapy with sodium–glucose cotransporter 2 (SGLT2) inhibitors and angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARBs) in the treatment of type 2 diabetes mellitus (T2DM) was not clear yet.
Research design and methods
A meta-analysis of randomized controlled studies (RCTs) was performed by searching in CENTRAL, Web of Science, PubMed, and Embase.
Results
Eight RCTs involving 6,386 participants were finally enrolled in this meta-analysis. Compared with placebo plus ACEI/ARBs, combined therapy with SGLT2 inhibitors and ACEI/ARBs induced a significant reduction in glycated hemoglobin (HbA1c) level by 0.43% (95% confidence interval [CI]: −0.55, −0.31), fasting plasma glucose level by 16.51 mg/dL (95% CI: −21.94, −11.08); systolic/diastolic blood pressure (BP) by 5.34 mmHg (95% CI: −7.47, −3.21)/1.27 mmHg (95% CI: −1.95, −0.59), respectively; and body weight (BW) by 1.45 kg (95% CI: −2.24, −0.65). Combined therapy was also found to be associated with a lower risk of adverse events. However, a higher risk of genital infections was observed with combination therapy than with placebo.
Conclusions
This combination therapy showed satisfactory effects on lowering glycemic, BW, and BP in the treatment of T2DM patients. The safety of this combination therapy was also acceptable.
