Abstract
We clinicaliye valuated 355 patients with urinarytract infections (UTI), suspected of having urosepsis at Tane General Hospital, and determined the usefulness of the biomarker procalcitonin (PCT) as an aid in predicting urosepsis. Clinical and microbiological data were collected. The logistic regression analysis was used to determine the risk factors of urosepsis. Of 355 patients, 169 patients (47.6%) were diagnosed with urosepsis. C-reactive protein (CRP) (OR 2. 633, p＜0. 001), PCT (OR 2. 153, p＝0. 003) and clinical diagnosis (calculous pyelonephritis OR 1. 886, p＝0. 019, acute prostatitis OR 3. 614, p＜0. 001) were established as the independent risk factors of urosepsis. Of 169 patients with urosepsis, 43 patients (25.4%) were diagnosed with severe urosepsis. In the severe urosepsis group, 2 patients with a PCT value ＜2.0 ng/ml were included. The mortalityrate in patients with severe urosepsis was 4.65% (2/43) in this study. We concluded that the PCT level could be a reliable marker suggestive of urosepsis. However, patients very early in the onset of infection mayhave a normal PCT value. It is essential to use all available clinical information when interpreting the results of a PCT measurement.
