Symptomatic urinary tract infection in pediatric patients--a developmental aspect

Area of Science:

• Pediatrics
• Infectious Diseases
• Nephrology

Background:

• Urinary tract infections (UTIs) are common in children, but clinical presentations and outcomes can differ based on age.
• Understanding these age-related variations is crucial for timely diagnosis and management.

Purpose of the Study:

• To investigate the age-specific clinical manifestations, radiological findings, and causative organisms of symptomatic urinary tract infections (UTIs) in a pediatric cohort.
• To identify age-related risk factors and complications associated with UTIs in children.

Main Methods:

• A cohort of 112 children across different developmental stages (neonates, infants, preschool, and school-aged children) were studied.
• Clinical presentations, radiological abnormalities, renal scarring, vesicoureteral reflux (VUR), and causative organisms were analyzed.
• Statistical analysis was performed to identify age- and sex-related differences and correlations.

Main Results:

• Clinical presentations varied by age group, with neonates presenting with sepsis, and loin pain, fever, diarrhea, and vomiting being common in older children and infants.
• Radiological abnormalities were more frequent in male school children and associated with fever in this group and intrauterine growth retardation in neonates.
• Renal scarring was predominantly observed in school children, while VUR was more common in infants. E. coli prevalence increased with age, from 48.3% in neonates to 74.5% in school children.

Conclusions:

• Symptomatic urinary tract infections (UTIs) exhibit significant age-related characteristics in children.
• Age influences clinical presentation, risk of radiological abnormalities, specific complications like renal scarring and VUR, and the predominant etiological agent (E. coli).
• These findings underscore the importance of age-specific approaches in managing pediatric UTIs.
