Abstract
Introduction: Urinary tract infection (UTI) is one of the most common bacterial infections in childhood which can contribute to high blood pressure and renal failure later in life. There are diffident methods for evaluation of a child with UTI for differentiation of cystitis from acute pyelonephritis. One of which is measuring protein in urine. The aim of this study is to investigate the role of UTI in provoking proteinuria.
Material and Methods: This is Quasi- experimental study, before and after, in patients with acute pyelonephritis in Mofid Children's Hospital during 2004-2006. All pyelonephritic patients were treated by intravenous ceftriaxone for at least for 10 days. Random urine samples were taken from all patients at the onset of admission before starting the antibiotic and at the ninth day of treatment for the evaluation of urine protein and creatinine.
Results: 152 children between 1 to 2 years of age entered the study. The prevalence of proteinuria in the acute phase of pyelonephritis was 94.8%. According to our study the prevalence of proteinuria during pyelonephritis is higher in children less than 2 years old (97.3%) and 20% of patients showed nephrotic range of proteinuria. In all cases random urine samples were normal after completion of treatment (p<0.005).
Conclusions: the results of this study illustrate that proteinuria has a high frequency during UTI and acute pyelonephritis. Proteinuria during pyelonephritis may be massive and in the nephrotic range but should not be the cause of concern because in the majority of cases it disappears following treatment.
