Why Are Children With Bronchiolitis At Risk Of Urinary Tract Infections?

Hendaus, Mohamed A

However, the above studies did not sub-categorize the prevalence of UTI in bronchiolitis per specific respiratory virus as a trigger. Hendaus et al 8 studied the prevalence of urinary tract infection in infants and children with bronchiolitis. The study included 835 pediatric patients with acute bronchiolitis. The mean (±SD) age at diagnosis was 3.47±2.99 months. There were 325 (39%) girls and 510 (61%) boys. Participants were divided into three groups: group 1 comprised of children hospitalized with bronchiolitis and a positive diagnosis for respiratory syncytial virus (RSV) bronchiolitis; group 2 comprised of children hospitalized with clinical bronchiolitis with no virus detected; and group 3 comprised of children hospitalized with clinical with bronchiolitis and a positive diagnosis respiratory virus other than RSV. After applying inclusion and exclusion criteria, RSV [3.4%] ). The definition of UTI was adopted from the American Academy of Pediatrics as clinicians should require both urinalysis results that suggest infection (pyuria and/or bacteriuria) and the presence of ≥50,000 colony-forming units (CFUs) per milliliter of a uropathogen cultured from a urine specimen obtained through catheterization or suprapubic aspirate. 26 The overall prevalence of UTI was 10%, and was most common in group 3 (13.4%) trailed by group 2 (9.7%), and was least common in group 1 (6%) (P=0.030). The most reasonable explanation of why the rate of UTI was higher in the study conducted by Hendaus et al 8 was because it was the first published study that sub-categorized the prevalence of UTI in bronchiolitis per specific respiratory virus as a trigger.
