Urinary Tract Infection in Childhood and Inflammatory Markers>

Area of Science:

• Pediatric infectious diseases
• Clinical pathology
• Biomarkers in infection

Background:

• Acute urinary tract infections (UTIs) are a frequent pediatric concern.
• Accurate diagnostic tools are crucial for effective management and predicting outcomes.
• Peripheral blood tests are commonly used but their correlation with UTI severity needs further investigation.

Purpose of the Study:

• To determine if peripheral blood test results correlate with urinary culture findings in children with UTI.
• To examine the relationship between peripheral blood markers and length of stay (LOS) in pediatric UTI patients.

Main Methods:

• Retrospective study of 135 pediatric patients admitted with UTI.
• Analysis of peripheral blood tests including white cell count (WCC), neutrophil count, and C-reactive protein (CRP).
• Correlation analysis between blood test results, urinary culture, and length of hospital stay.

Main Results:

• 11.9% of patients presented with normal WCC, neutrophil count, and CRP < 5 mg/L.
• No significant association was found between normal blood test results (WCC, neutrophils, CRP) and LOS in this subgroup.
• No significant correlation between LOS and E. coli infection was observed in patients with normal blood markers.

Conclusions:

• Peripheral blood tests may not be sufficient to rule out severe UTI or predict LOS in all pediatric cases.
• Further research is needed to identify reliable biomarkers for UTI severity in children.
• Clinical assessment remains critical in managing pediatric UTIs.
