Comparison of Clinical, Etiological and Antibiotic Sensitivity Patterns of UTI in CAKUT and Non CAKUT Children
Abstract
Background: Urinary tract infections (UTIs) are one of the most common bacterial infections in children. Congenital anomalies of the kidney and urinary tract (CAKUT) are a major cause of UTIs in this population.
Objective: To compare clinical, etiological and antibiotic sensitivity patterns of UTIs in CAKUT and non-CAKUT children.
Study Design: Prospective comparative study.
Place and Duration: The study was conducted at the department of Pediatric Nephrology, The Children's Hospital Lahore from August 2023 to January 2024.
Methods: 68 children with and without CAKUT having UTI were evaluated. Data regarding demographics, clinical presentation and antibiotic sensitivity pattern was collected. Susceptibility testing was done according to CLSI recommendations.
Results: 34 patients with UTI in CAKUT group (Group A) had male predominance (73.5%) while children without CAKUT (Group B) were predominantly females (55.9%). Mean age in Group A (38.9 months) was less than that in Group B (53.9 months). The common presentations in both the groups were pyelonephritis and cystitis. Vesico-ureteric reflux (32.4%) and posterior urethral valves (29.4%) were the most common CAKUT findings. Majority of patients with CAKUT had Pseudomonas UTI (32.4%) while E. coli (35.3%) was common in children without CAKUT. Fosfomycin, Colistin, Linezolid and Polymyxin B had low resistance amongst both groups. The association between CAKUT and atypical uropathogens was not found to be statistically significant (p = 0.287).
Conclusion: Differences exist in clinical presentation, etiology and antibiotic sensitivity patterns specific to UTI in CAKUT and non-CAKUT children. A high resistance pattern was found amongst common antibiotics.
