The Pattern of Organism Causing Urinary Tract Infection in Diabetic and Non Diabetic Patients in Bangladesh

Abstract

Urinary tract infection (UTI) is common both in the diabetic and non-diabetic patients. The widespread use of antimicrobial agents leads to emergence of resistant microorganisms. Since the pattern of bacterial resistance is constantly changing, the monitoring of the antimicrobial susceptibilities of the predominantly isolated organisms becomes more important. Aim of this study was to determine the etiologic agents and their antibiotic sensitivity pattern in both diabetic and non-diabetic patients with urinary tract infection (UTI). A total of 288 diabetics (196 female and 92 males) and 63 non diabetic patients (43 female and 20 males) with symptomatic UTI were included in this study. Among the study cases, 43.8% diabetic patients and 42.9% non-diabetic patients had positive growth from urine. Rate of isolation of Escherichia coli in diabetic was less (61.8%) compared to non diabetic (77.8%). Rate of other organisms isolated in diabetic and non diabetic patients were respectively: Klebsiella sp 6.9% vs 3.7%, Enterococcus 12.2% vs3.7%, Pseudomonas species 3.8% vs 0%, Candida species 4.6% versus 3.7%, Staphylococcus aureus 4.6% versus 7.4% etc. E coli isolated from diabetic patient was significantly (p<0.05) less sensitive to ceftriaxone, ceftazidime, cefuroxime, netilmicin, gentamicin, ciprofloxacin and nitrofurantoin than that of non diabetic patients. In addition, isolation rate of the Extended Spectrum Beta Lactamase producing gram negative bacilli was found higher among diabetic population (47.8%) compared to the non-diabetics (9.1%).
