Relative frequency of urinary tract infections in patients affected by diabetes mellitus type 2 treated with metformin and SGLT2 inhibitor. Network meta-analysis
Abstract
Introduction and aim: The of this research was to conduct a network meta-analysis based on a systematic literature search to compare the relative frequency of urinary tract infections using sodium-glucose cotransporter-2 (SGLT2) inhibitors combined with metformin in the therapy of type 2 diabetes. Method: MEDLINE and EMBASE databases were searched to identify publications of randomized, controlled trials investigating SGLT2 inhibitors combined with metformin in the therapy of type 2 diabetes and providing information on the frequency of urinary tract infections. Results: 10 165 unique citations were screened to identify 10 publications to be included in the network meta-analysis. The network meta-analysis showed reduced risk of urinary tract infections for low-dose ertugliflozin compared to other SGLT2 inhibitors (ertugliflozin 5 mg vs. empagliflozin 10 mg: RR: 0.606, 95% CrI: 0.264-1.415; ertugliflozin 5 mg vs. dapagliflozin 10 mg: RR = 0.853, 95% CrI: 0.301-2.285). For high-dose comparisons, empagliflozin 25 mg showed reduced risk of urinary tract infections compared to both ertugliflozin 15 mg (RR = 0.745, 95% CrI 0.330-1.610) and dapagliflozin 10 mg (RR = 0.680, 95% CrI: 0.337-1.289). The difference between active substances and their doses was not statistically significant for the relative frequency of urinary tract infections. The meta-regression revealed a statistically significant association between baseline fasting plasma glucose level and relative frequency of…
