Clinical and Laboratory Profile of Urinary Tract Infections in Type 2 Diabetics Aged over 60 Years
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 4
Abstract
Introduction: Urinary tract infections are frequently encountered among diabetic patients and the incidence rate increases with age. There have been growing research to identify the clinical profile of urinary tract infections in diabetic patients. However, such studies on elderly patients are rare. Aim: To determine the risk factors, clinical/laboratory profiles, causative organisms and antimicrobial susceptibilities in type 2 diabetics aged over 60 years. Materials and Methods: This prospective single centre study was conducted at NRI Medical College and General Hospital, Guntur, India, between November 2012 and November 2014. A total of 100 consecutive patients with type 2 diabetes mellitus, aged over 60 years, with symptoms suggestive of urinary tract infection were examined. Subsequently, the demographic characteristics, detailed medical history, signs/symptoms of urinary tract infections, laboratory investigations for blood and urine samples, ultrasound abdomen findings were compared between bacteriuric and non bacteriuric patients. In addition, the organisms in urine cultures and antibiotic sensitivity patterns were investigated for bacteriuric patients. Two groups were compared using the Mann-Whitney test for continuous variables and the Chi-square or the Fisher’s exact test for categorical respectively. Results: Bacteriuria was found in 43% of type 2 diabetic patients aged over 60 years. Comparative analysis revealed that bacteriuria was more common among patients with female gender (p=0.028), diabetes duration of >15 years (p=0.011) and diabetes complications such as neuropathy (p=0.027) and diabetic foot (p=0.003). Age and uncontrolled fasting blood sugar or HbA1c levels did show an increased propensity for developing urinary tract infections. Increased frequency (76.7%), and urgency (67.4%), dysuria (65.1%) were significantly more common among bacteriuric patients than that in nonbacteriuric patients (p<0.05). Urine culture analysis revealed that E. coli (69.8%) was the most common causative organism, followed by Klebsiella (16.3%). Majority of isolated organisms were sensitive to antimicrobial agents like nitrofurantoin and imipenem. Conclusion: Bacteriuria was very common in elderly patients with diabetes. The observed trends in risk factors, clinical profile, laboratory profile, causative organism patterns, and antimicrobial susceptibilities will help to add the growing literature on this topic.
