Özet
Objective: Early diagnosis of urinary tract infection (UTI) is important to reduce short- and long-term complications. To this end, effective biomarkers\rare needed. Our aim was to evaluate the role of copeptin in the diagnosis of UTI and in distinguishing upper from lower UTI compared to other\rinflammatory markers.\rMethods: The diagnosis of UTI was based on the presence of typical clinical symptoms and a positive urine culture. The control group was formed by\rhealthy children without signs or symptoms of infection. Complete blood count, CRP, ESR, serum IL -6, NGAL and copeptin were evaluated.\rResults: The study group included 41 patients with UTI and 41 healthy controls. The patients were 5 (0.8-15) years old and 65.9% of them were female.\rIn the patients with UTI, in addition to total WBC (p<0.001) and NGAL (p=0.031), copeptin was also increased (147.9(60.8-361.9) vs. 69.7(24.2-303) ng/\rml, p<0.001). Copeptin could diagnose UTI at a cut-off value of 81.8 ng/ml (p<0.001, sensitivity 80.4%, specificity 60.5%). Within the UTI group, 10 had\rupper UTI and 31 had lower UTI. In the upper UTI group WBC (p=0.019), CRP (p<0.001), ESR (p<0.001) and NGAL (p=0.046) were higher. Copeptin did\rnot differ between upper and lower UTI groups (p=0.82). Copeptin correlated with IL -6 and NGAL (r²=0.23, p=0.002; r²=0.89, p<0.001, respectively).\rConclusion: Copeptin is a useful biomarker to use in the diagnosis of childhood UTI, but more comprehensive studies are needed to evaluate its role\rin distinguishing upper from lower UTI.
