Gender Differences in the Clinical Profile of Sodium-Glucose Cotransporter-2 Inhibitor-Related Urinary Tract Infections.

Background Sodium-glucose cotransporter-2 inhibitors (SGLT2Is) are a novel class of oral antidiabetic agents with proven cardiovascular and mortality benefits. By promoting glucosuria, SGLT2Is increase the risk of genital and urinary tract infections (UTIs), which remain uncomplicated in most cases. Comparative studies detailing the gender differences in the clinical profile of SGLT2I-related UTIs (SUTIs) are lacking. Hence, this study was designed to investigate the gender-related differences in the clinical profile of SUTIs. Methodology This prospective study enrolled 100 consecutive diabetes mellitus patients with UTI symptoms who were on SGLT2Is. In addition to collecting clinical details, patients were subjected to the following investigations: complete blood counts, urea, creatine, liver function, lipid components, urine analysis, urine culture, and ultrasonography. Results Females (n = 80) outnumbered males (n = 20). Although females were younger than males (53.68 ± 10.26 vs. 63.30 ± 10.75 years, p = 0.003), body mass index (29.84 ± 7.22 vs. 24.62 ± 3.10 kg/m2, p = 0.008) and waist circumference (103.01 ± 14.49 vs. 93.75 ± 4.50 cm, p = 0.109) were higher in females. About 22.5% of females had undergone hysterectomy. The mean duration of diabetes mellitus was longer in males (10.64 ± 6.74 vs. 7.78 ± 4.75 years), whereas the median duration of SGLT2I use (4 (interquartile range (IQR) = 1-12) vs. 3 (IQR = 2-4) months) and mean HbA1c levels were not different between the two groups. A greater proportion of males were complicated by retinopathy (55% vs. 15%) and proteinuria (65% vs. 17.5%), while neuropathy (85% vs. 71.25%) rates were similar. Overall, 35% of males had complicated UTIs (renal abscess, pyelonephritis, prostatic abscess) compared to only 3.75% of females (p = 0.001). Conclusions The majority of SUTIs are uncomplicated in females whereas in males one-third are complicated infections. Although females with SUTI had a higher prevalence of obesity and dyslipidemia, males had a longer duration of diabetes mellitus and higher retinopathy prevalence. Extreme caution should be exercised in patients at risk for SUTI before prescribing SGLT2I.
