Supplementation with Highly Standardized Cranberry Extract Phytosome Achieved the Modulation of Urinary Tract Infection Episodes in Diabetic Postmenopausal Women Taking SGLT-2 Inhibitors: A RCT Study
Abstract
Urinary tract infections (UTIs) are the most common bacterial infections in postmenopausal women, and women with diabetes are possibly at a higher risk. The aim of this study is to evaluate the potential benefit on the prevention of UTI episodes, assessed by urinalysis and urine culture (primary outcome) after two, four and six months, of daily oral dietary supplement (120 mg highly standardized cranberry extract phytosome), compared to placebo, in diabetic postmenopausal women taking SGLT-2 inhibitors. Forty-six subjects (mean age 72.45 ± 1.76) completed the study (23 placebo/23 supplement). Considering UTI episodes, during the six-month supplementation period, an increase of 1.321 (95% CI: −0.322; 2.9650) was observed in the placebo group, while it remained at a steady value of 0.393 (95% CI: −4.230; 5.016) in the supplemented group. Regarding UTI episodes, in both groups, interaction between times for supplementation was statistically significant (p = 0.001). In particular, at follow-up 4, 9% of the placebo group showed infection versus only 3% with cranberry supplementation. Glycaemia and glycated hemoglobin values (secondary outcomes) were not modified at the end of six months with respect to the basal values in both groups, as expected. While in terms of quality of life per the SF-12 health questionnaire, there were no differences between the two groups, an improvement in SF-12 quality of life was observed in both groups (six months vs. basal). In conclusion, highly…
