Infectious Diseases Concomitant with Urinary Tract Infections in Children

65 Abstract: Urinary–tract infection (UTI) is one of the most common infectious diseases in children; however, the significance of combined infection in the pathogenesis of UTI remains uncertain. Of 48,382 patients discharged from Texas Children’s Hospital from July 1, 1991, to June 30, 1994, 1,221 (2.5%) were discharged with a diagnosis of UTI. We retrospectively reviewed the files of these 1,221 patients to assess for concomitant infections and causative microorganisms in patients with first–time UTI, no urologic abnormalities, and no other major diagnoses. Of the 1,221 patients, 511 (42%) had first–time UTI with no urological abnormalities or other major diagnoses, of which 449 (87.8%) had UTI only, and 62 (12.1%) had concomitant infectious diseases. The 62 patients with concomitant infections comprised the study group for our series. There were 38 boys and 24 girls with a mean age of 2.9 years. Most of the patients (42/62) were younger than 1 year old. Eihteen patients had otitis media, 16 had acute pneumonia, 14 had acute bronchiolitis, 5 had acute gastroenteritis, 4 had meningitis, 2 had upper respiratory tract infection, 1 had eye infection, 1 had vaginitis, and 1 had vulvovaginitis and salpingo–oophoritis. E. coli was the most common pathogen, accounting for 34 (51.5%) of the organisms isolated in these patients, followed by Klebsiella, which accounted for 10 (15.2%) of the isolated organisms.
