We aimed to determine the influence of diabetes mellitus (DM) on uropathogens and antibiotic resistance pattern in urinary tract infection (UTI) in our center. Three hundred fifty-five DM patients and 165 non-DM patients with UTI were included in this retrospective study. Urine samples were processed in the laboratory following standard protocol. Mean age was higher in DM group (63.9 ± 12.4 vs 59.6 ± 17.3 years, respectively, P = 0.001). Females showed much higher UTI prevalence in both groups (85.6% in DM vs 70.3% in non-DM group, P = 0.000). Mean HbA1c level on admission was 9.3% (78 mmol/mol). Mean duration of DM was 13.9 ± 8.5 yr. E.coli was the predominant uropathogen for both (67.3% in DM and 61.8% in non-DM group). Most isolated microorganisms were sensitive to nitrofurantoin (87.0% in DM, vs 83.6% in non-DM group, P = 0.265). Mean DM duration of higher than 10,5 years showed greatest risk of multidrug resistance (MDR) (AUC = 0.58, sensitivity of 63.7% and specificity of 50%, P = 0.019). Diabetic patients with UTI had poor glycemic control and long-standing DM. Nitrofurantoin was the most appropriate antimicrobial agent for empirical use. The MDR was higher in patients with DM lasting longer than 10.5 years.
