Urinary Tract Infection: Prevalence, Risk Factors, Bacterial Etiologies and Antimicrobial Resistance Profile among Egyptian Diabetic Patients

Diabetic patients are more prone to infections due to impaired immune status. One of most frequent infections in diabetic patients are urinary tract infection (UTI). The aim of the work was to study the prevalence and associated risk factors of UTI among diabetic patients attending the outpatient clinics of Menoufia university hospital, and to assess the pattern of antimicrobial sensitivity of isolated organisms. A pre-designed questionnaire was used to collect information about age, sex and residence, smoking habits, and type and duration of diabetes. Laboratory investigations including blood analysis for glucose level, HBA1c, leucocytic count, urine culture and antimicrobial sensitivity testing were done. The prevalence of UTI was 51.3%, and the most significant risk factors associated with infection were older age, being female, BMI > 30, duration of diabetes > 10 years, together with uncontrolled diabetes. Residence, smoking, and type of diabetes were found to be insignificantly associated with UTI. Age, duration of diabetes, and HBA1c were found to be independently associated with UTI. Common isolated organisms in order of frequency were E. coli, Klebsiella, and Coagulase negative staph. More than 50% of isolates were resistant to one or more antibiotic on antimicrobial antibiotic sensitivity testing. The study concluded a high prevalence of UTI among studied patients. Proper control of diabetes with regular screening for HBA1c and UTI among diabetic patients is needed.
