Predictive Factors for Urinary Tract Infections in Patients with Type 2 Diabetes.

Patients with diabetes (DM) are at an increased risk of infection, with urinary tract infections (UTIs) being common among individuals with type 2 DM (T2D). The aim of this study was to determine the prevalence and risk factors for UTIs among hospitalized T2D patients from Timișoara, Romania. The hospital records of 1139 T2D adult inpatients who were ordered to provide urine cultures during hospitalization were reviewed. The prevalence of UTIs among T2D patients was 19.7%, and was higher in women than in men (27.5% vs. 9.8%, < 0.0001). Patients with UTIs presented a significantly older age, a longer duration of DM, a higher BMI, higher levels of HbA1c, higher renal function parameters, and more frequent DM-related complications and comorbidities than patients without UTIs. The following predictors were associated with increased UTI risk: age (OR = 1.05, < 0.0001); duration of DM (OR = 1.04, < 0.0001); BMI (OR = 1.05, < 0.0002); HbA1c levels (OR = 1.58, < 0.0001); female gender (OR = 3.47, < 0.0001); and the presence of retinopathy (OR = 1.47, = 0.0118), chronic kidney disease (OR = 3.98, < 0.0001), distal symmetric polyneuropathy (OR = 7.65, < 0.0001), and cerebrovascular disease (OR = 4.88, < 0.0001). The use of sodium-glucose co-transporter 2 (SGLT2) inhibitors did not influence the risk of developing UTIs. T2D patients with prolonged disease duration, poor glycemic control, and DM-related complications are at an increased risk of developing UTIs. Therefore, a targeted therapeutic strategy addressing these risk factors is essential.
