Fever, bacteriuria and concomitant disease in children with urinary tract infection.

Author information

Department of Pediatrics, Gothenburg University, Sweden.


A total of 124 children aged 0.2 to 6 years were enrolled in a study of first time febrile urinary tract infection. The patient population was stratified in groups according to the stringency of criteria for fever and bacteriuria and the presence of concomitant disease. The major group of 88 patients consisted of children with fever greater than or equal to 38.5 degrees C measured at the hospital within 24 hours of diagnosis, bacteriuria verified by suprapubic bladder aspiration or repeated cultures of voided urine, but without concomitant disease. These children were mainly infected with attaching Escherichia coli specific for galactose alpha (1----4) beta galactose containing receptors and had laboratory evidence of inflammation. Another group of 11 children were distinguished with strictly defined bacteriuria and concomitant disease. These children were infected with nonattaching bacteria and had lower concentrations of C-reactive protein in serum and lower microsedimentation rates than the major group. Five of these children had a reduction in renal concentrating capacity. The study emphasizes the heterogeneity among patients with fever and bacteriuria but does not rule out the possibility of renal involvement in any subgroup.
