Study on Asymptomatic Bacteriuria in Diabetic Patients
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 2
Abstract
Introduction: The incidence of diabetes mellitus is escalating remarkably. Diabetes mellitus has a number of long term effects on the genitourinary system. Asymptomatic bacteriuria (ASB) is a common problem in diabetic patients and is associated with increased risk of septicemia and pyelonephritis if untreated. This study was carried out to determine the prevalence of asymptomatic bacteriuria in diabetic patients and the susceptibility pattern of the pathogens isolated. Material and methods: One hundred type -2 diabetics (50 males and 50 females) without genitourinary symptoms or abnormalities were included in the study. Midstream urine samples were collected from the study participants after getting informed consent. Urine samples were processed and examined for the various pathogens using the standard microbiological procedures. The spectrum of uropathogens causing asymptomatic bacteriuria and their antibiotic susceptibility profile was noted. Results: Among the 100 diabetic patients, 32 (32%) had asymptomatic bacteriuria of which 20 (62.5%) were females and 12 (37.5%) were males. Escherichia coli (37.5%) was the most prevalent organism followed by Klebsiella pneumoniae (18.7%), Enterococcus faecalis (15.6%), Staphylococcus aureus (9.4%), Pseudomonas sp (6.3%), Proteus sp (6.3%), Coagulase Negative Staphylococcus(3.1%), and Candida sp (3.1%).The antibiotic susceptibility testing revealed that most of the isolated organisms were resistant to nalidixic acid, ampicillin, ciprofloxacin and cefotaxime. Conclusion: The overall prevalence of ASB in the diabetic patients was 32%. Female sex was found to be a significant risk factor in developing asymptomatic bacteriuria. E.coli was the most prevalent organism. Therefore close monitoring of diabetic status and regular screening for ASB in diabetics would help resolve ASB related complications in diabetes. Further studies substantiating the efficacy of antimicrobial therapy in preventing complications secondary to asymptomatic bacteriuria in diabetic patients is needed.
