Prevalence of urinary tract infection in diabetic patients and identification of the causal microorganisms


Background and objective: Urinary tract infection (UTI) is a condition in which the urinary tract is infected with a pathogen causing inflammation. One of the predisposing factors for UTIs is diabetes mellitus (DM), spillage of glucose into the urine provide a good culture medium for bacteria. The objectives of this study were to evaluate the distribution of UTIs among diabetic patients of both genders with studying the effect of some relative factors, and identifying types of the causal microorganisms. Methods: Diabetic patients (type1 and 2), from both genders were included in this study. All patients were interviewed. Uncontaminated urine samples were collected for microscopic and macroscopic analysis. Isolations and identifications of bacteria were done by standard methods. Results: Out of 150 diabetic patients, 53 (35.33%) have UTI. Gender, middle age and high level of proteinuria were risk factors, while type and duration of DM with its type of treatment, body mass index (BMI), and hypertension were non significant. The isolated types of pathogens were Escherichia coli (45.3%), Klebsiella pneumoniae (15.1%), Staphylococcus saprophyticus (15.1%), Citrobacter diversus (11.3%), Candida albicans (7.5%) and Staphylococcus aureus (5.7%). Conclusion: This study revealed that diabetic females were most susceptible to get UTIs than diabetic males. In both genders the most reliable age for UTI were between 31-40 years. The results showed that the level of proteinuria was higher in patients suffering from UTIs associated with DM, which considered as a risk factor. Certain types of microorganisms were isolated; the most common types were Escherichia coli, Klebsiella pneumoniae and Staphylococcus saprophyticus.
