Relación clínica entre ictericia no inmune e infección urinaria en recién nacidos.

Introduction: this study aims to analyze the relationship between non-immune jaundice and urinary tract infection (UTI) in full-term neonates. Additionally, it investigates the frequency of this association in jaundiced patients without fever but with evidence of UTI. The study seeks to determine if UTI is a contributing factor to neonatal jaundice and explore other potential associated factors. Methodology: a prospective cross-sectional descriptive study was conducted using medical records of neonates who developed idiopathic jaundice within the first 15 days of life, between January 2019 and July 2021. Parametric description of the variables was performed, along with an analysis of the medical records of neonates treated in a health institution in Barranquilla, Atlántico. Results: females showed a predominance in the association between non-immune jaundice and UTI, accounting for 54 %, compared to males at 46 %. The most common age range for detecting non-immune jaundice was between 4 to 8 days of life, with Escherichia coli being the most frequently identified causative microorganism for UTI. Conclusions: in neonates under 10 days of age diagnosed with jaundice requiring hospitalization for phototherapy based on Bhutani curves, UTI should be considered as part of the clinical picture or a predictive factor. Urine culture should be included in the diagnostic protocol for early detection of UTI in these neonates. [ABSTRACT FROM AUTHOR]
