Introduction: Asymptomatic bacteriuria (ASB), believed to precede symptomatic urinary tract infection (UTI) in diabetes mellitus, has geographical variation in microbial pattern and risk factors. However, data from the Eastern part of India are still lacking. Materials and Methods: A prospective longitudinal study was performed over 80 otherwise healthy type 2 diabetes patients with a follow-up for one year to (1) estimate the prevalence of ASB and its association with age, gender, duration of diabetes, and renal and glycemic status; and (2) identify the antibiotic sensitivity pattern of uropathogens as well as evaluate the usefulness of microbial pattern as a predictor of symptomatic UTI. Results: ASB was prevalent in 21.25% of type 2 diabetes population in our study. Klebsiella sp emerged as the commonest cause among males. The only risk factor for ASB was found to be long-standing type 2 diabetes. There was no association with age, gender, or recent glycemic status. Bacteriuric patients with worse baseline HbA1C values were at greater risk of UTI. Female diabetic patients with ASB due to Escherichia coli had significantly greater risk of developing UTI within one year. Conclusion: A large-scale prospective study reproducing similar findings will genuinely obviate the need to review recommendations on screening of ASB due to E. coli in females with long-standing diabetes and poor glycemic control. Early adoption of stringent HbA1C lowering strategy and measures to improve genital hygiene can help prevent symptomatic UTI in these patients.
