      months of age.

AB  - BACKGROUND: The 2011 American Academy of Pediatrics urinary tract infection (UTI)
      guideline suggests incorporation of a positive urinalysis (UA) into the
      definition of UTI. However, concerns linger over UA sensitivity in young infants.
      Infants with the same pathogenic organism in the blood and urine (bacteremic UTI)
      have true infections and represent a desirable population for examination of UA
      sensitivity. METHODS: We collected UA results on a cross-sectional sample of 276 
      infants <3 months of age with bacteremic UTI from 11 hospital systems.
      Sensitivity was calculated on infants who had at least a partial UA performed and
      had >/=50 000 colony-forming units per milliliter from the urine culture.
      Specificity was determined by using a random sample of infants from the central
      study site with negative urine cultures. RESULTS: The final sample included 245
      infants with bacteremic UTI and 115 infants with negative urine cultures. The
      sensitivity of leukocyte esterase was 97.6% (95% confidence interval [CI]
      94.5%-99.2%) and of pyuria (>3 white blood cells/high-power field) was 96% (95%
      CI 92.5%-98.1%). Only 1 infant with bacteremic UTI (Group B Streptococcus) and a 
      complete UA had an entirely negative UA. In infants with negative urine cultures,
      leukocyte esterase specificity was 93.9% (95% CI 87.9 - 97.5) and of pyuria was
      91.3% (84.6%-95.6%). CONCLUSIONS: In young infants with bacteremic UTI, UA
      sensitivity is higher than previous reports in infants with UTI in general. This 
      finding can be explained by spectrum bias or by inclusion of faulty gold
      standards (contaminants or asymptomatic bacteriuria) in previous studies.
