Microbiological Profile and Antibiotic Resistance Pattern of Uropathogens in Diabetic and Non-Diabetic Patients

 Urinary tract infection (UTI) is one of the most common human infections which is more prevalent especially in patients with diabetes mellitus. The aim of this study was to compare the uropathogens isolated from the urine culture of diabetic and non-diabetic patients and their antibiotic resistance pattern in patients admitted to Imam Khomeini Hospital in Ardabil from 2012 to 2013.

In this descriptive cross-sectional study, the medical records of all patients admitted to Imam Khomeini University Hospital in Ardabil province from the beginning of 2012 to the end of 2014 were reviewed and the required information including age, sex, or the absence of diabetes was recorded.

E. coli was the most common uropathogens isolated from both diabetic (58.1%) and non-diabetic (53.6%) patients followed by yeast (19.4%) in both groups. Other common organisms in diabetic and non-diabetic patients were Staphylococcus aureus (8.4%) and coagulase negative Staphylococcus (7.1%), respectively. Among diabetic patients, E. coli had the highest sensitivity to polymyxin (100%), tetracycline (100%), and amikacin (88.9%). In non-diabetic patients, E. coli had the highest sensitivity to amikacin (90.4%), nitrofurantoin (86%), cefoxitin (85.3%), and gentamicin (82.1%).

Our findings indicated that susceptibility profiles of uropathogens are different in diabetic and non-diabetic individuals, therefore, empirical treatment for diabetic and non-diabetic patients will be different.
