Objective:Patients with diabetes mellitus have a higher prevalence of asymptomatic bacteriuria and incidence of urinary tract infections compared to patients without diabetes mellitus. A prospective pilot study was conducted to determine the frequency of association of asymptomatic bacteriuria among patients with diabetes mellitus in comparison to control group without diabetes mellitus. Methods:Urine specimens were processed by microscopy and culture following standard guidelines. The spectrum of uro-pathogens causing asymptomatic bacteriuria and their antibiotic susceptibility profile were noted. Results:Asymptomatic bacteriuria was seen more commonly in patients with diabetes mellitus (4%) than in healthy control subjects. Asymptomatic bacteriuria was not seen in the non - diabetic individuals under control grou p . Three out of the four patients with asymptomatic bacteriuria had associated complications of diabetes mellitus. Enterococcusfaecalis( 2,50%),Staphylococcus saprophyticus (1, 25%) and Escherichia coli (1, 25%) were the organisms isolated from patients with asymptomatic bacteriuria. Staphylococcus saprophyticus isolate was mostly sensitive to antimicrobials tested. Enterococcus faecalis was sensitive to ampicillin. Escherichia coli isolate was multi-drug resistant. Conclusion: Asymptomatic bacteriuria was more common among patients with diabetes mellitus than in healthy control subjects. Further, long term studies investigating the occurrence of complications secondary to asymptomatic bac te r iur ia in patie nts with diab ete s me llitu s a nd r a ndomize d control studies for studying the efficacy of antimicrobial therapy in preventing further complications in diabetes mellitus patients in Indian setups are needed. |
