ABSTRACT
Introduction
Sodium glucose cotransporter-2 inhibitors (SGLT2is) are an emerging class of drugs with wide indications. Controversial evidence exists regarding the risk of urinary tract infection (UTI) and genital infections (GI) with SGLT2is paving way for undertaking this network meta-analysis and meta-regression study.
Methods
Data from randomized trials evaluating SGLT2is reporting the number of patients with UTI and GI were included. Odds ratios (OR) with 95% confidence intervals (95% CI) were the effect estimates. Meta-regression analysis identified risk factors. Number needed to harm (NNH) was estimated.
Results
Two hundred and sixty-four articles were included [UTI (213 studies; 150,140 participants) and GI (188 studies; 121,275 participants)]. An increased risk of UTI (OR: 1.11; 95% CI: 1.06, 1.16) and GI (OR: 3.5, 95% CI: 3.1, 3.9) was observed. Men showed a lower risk of UTI (OR: 0.2; 95% CI: 0.2, 0.3) and GI (OR: 0.4; 95% CI: 0.4, 0.5). Meta-regression analyses revealed BMI ≥ 30 kg/m2 and duration of SGLT2i treatment for ≥6 months as risk factors. NNH was 16 for UTI and 25 for GI.
Conclusion
SGLT2is increase the risk of UTI and GI that needs to be incorporated in the treatment guidelines with precautions in high-risk patients.
