Are the Clinical outcomes of Neonates and Infants Under 2 Months Old with Urinary Tract Infections Similar to those in Infants 2 to 12 Months Old?

Clinical and laboratory features of urinary tract infections in young infants

“…E. coli was the main microorganism in our cohort - 56.9% of cases. This prevalence was lower than previously published results in this age group (62%-88%), 1 , 4 , 6 , 9 , 10 , 17 but higher than the 41.7% prevalence reported by Chen et al 23 in young infants with elevated blood bilirubin secondary to UTI. Other microorganisms that should be considered when initiating empirical antimicrobial therapy are: K. pneumoniae (18.5%) and E. faecalis (7.7%).…”

“…There were three times more cases among females, concurring with previous studies. 1 , 6 , 9 , 10 , 19 , 20 Fever without localizing signs was the main presenting sign (77.8% of cases). As in previous papers, 15 , 21 the complete blood count and the CRP were of little clinical use in the diagnosis of UTI; the white blood counts were within normal limits, and 30.5% of CRP tests were within normal.…”

“…It is relevant to consider that UTI may be the first sign that a child has a congenital anomaly of the kidney or urinary tract. 6 , 8 , 10 Given the retrospective nature of this study, we were unable to accurately characterize imaging methods in the evaluation of anatomical changes of the urinary tract in our cohort. We also had no access to prenatal ultrasounds of these infants to check for any diagnosis of renal and urinary malformations.…”
