Management of Febrile Urinary Tract Infection With or Without Bacteraemia in Children: A French Case-Control Retrospective Study
Abstract
Background: Febrile urinary tract infections (FUTIs) are common among children, and are associated with a bacteraemia between 4 and 7% of cases. No data is available concerning the management of children with a bacteraemic FUTI.Objectives: To compare the antibiotic treatment (parenteral and total duration) among children with bacteraemic and non-bacteraemic FUTIs, and the mean hospital length of stay (LOS); to describe clinical, microbiological and imaging features of children with bacteraemic and non-bacteraemic FUTIs and observed management modifications when the blood culture was positive.Methods: A retrospective case-control study between 2009 and 2015 at Robert Debré's Pediatric Emergency Department (Paris, France). Children with a bacteraemic FUTI were included and matched for age and sex with two children with a non-bacteraemic FUTI.Results: We included 50 children with a bacteraemic FUTI matched to 100 children with a non-bacterameic FUTI. The mean duration of parenteral antibiotics was longer for bacteraemic children (6.7 vs. 4.0 days, p < 0.001) but this difference was only significant in children > 28 days-old. The mean total duration of antibiotic was similar (11.3 vs. 11.6 days, p = 0.61). The mean LOS was longer for bacteraemic children (5.1 vs. 2.0 days, p < 0.001) but this difference was only significant in children > 28 days-old. A positive blood culture changed the management in 66% of patients. Clinical features at presentation were comparable. Bacteraemic patients had a higher procalcitonin (p = 0.006) and C-reactive protein (p = 0.01), lower mean lymphocyte count (p < 0.001).Conclusions: A bacteraemic FUTI in children induced a longer duration of parenteral antibiotic treatment, a longer hospitalization in children > 28 days-old, and a modification of management for 66% of patients.
