title: Frequency, risk factors, and responsible pathogenic microorganisms of asymptomatic bacteriuria in patients with type 2 diabetes mellitus.
abstract: Urinary tract infection is a serious problem in diabetic patients, and asymptomatic bacteriuria (ASB) in these patients is a risk factor for pyelonephritis and renal dysfunction. In the present study, we investigated the relationships between age, body mass index, duration of diabetes, HbA1c level, glucosuria, glomerular filtration rate and microalbuminuria in type 2 diabetic patients with ASB. One hundred and twenty-three patients with type 2 diabetes mellitus were included in the study. The patients were divided into two groups according to ASB; Group I consisted of 22 patients with ASB, and Group II of 101 patients without ASB. There were no significant differences between the groups in regard to age, body mass index, creatinine clearance or microalbuminuria, while there were significant differences in HbA1c, duration of diabetes mellitus, glucosuria and pyuria (P < 0.05). The most commonly isolated microorganism was Escherichia coli. The present study identified the duration of diabetes, high HbA1c, glucosuria and pyuria as risk factors for ASB in type 2 diabetic patients.
