Abstract

Background and aims: There is evidence that patients with diabetes have an increased risk of asymptomatic bacteriuria and urinary tract infections (UTIs). UTI is the most common bacterial infection in diabetic patients. The aim of this study was to assess the prevalence of UTIs among hospitalized diabetic patients and to identify the most frequent bacteria responsible for UTI. Material and methods: The study population included 1470 diabetic patients (847 women and 623 men), admitted to the Diabetes Clinic of the Emergency Clinical County Hospital Timişoara, between January and December 2012. We collected patients’ personal history data and performed urine cultures. For statistical analysis we used Graph Pad Prism 5; the significance of the difference between the percentage values was assessed using Fisher’s exact test. Results: From the total number of patients, 158 had positive urine cultures, meaning 10.7%. Out of the total number of 158 UTIs, 124 (78.4%) were asymptomatic bacteriuria. The most frequent bacteria involved in UTI was Escherichia coli (68.9%). Conclusion: UTIs are frequent in diabetic patients. Because of the great proportion of asymptomatic forms among diabetic patients, the urine culture should be performed in all hospitalized patients with diabetes.
