Estimation of IL-6 and IL-8 in the Urine and Serum of Children with Urinary Tract Infection

Urinary tract infection (UTI) is defined as the presence of bacteria in urine along with symptoms of infection.UTIs occurs in 1.1% of girls and 1.4% of boys in the first year of life. The aim of the study was to assessthe usefulness of measurement of pro-inflammatory interleukin (IL)-6 and IL -8 concentrations in the urineand serum of children with UTI. A total of Eighty serum sample and seventy tow urine sample have beencollected from children with urinary tract infection, Their age ranged between 33days- 12 years old, fifty sixchildren of the same age collected as controls .Urine and serum IL-6 and IL-8 concentrations of both groupswere measured and compared. Urine and serum concentrations of IL -8 were significantly higher in childrenwith UTI compared with controls group (P = 0.0001, P = 0.0002) respectively, while there was no significantdifferent in urine and serum concentration of IL-6 of children with UTI and controls group(P = 0.1199 , P=0.572) respectively. The results demonstrate that IL-8 is a good biomarker for urinary tract infection, whileIL-6 is not.
