Predictive factors for @entity8 in febrile urinary tract infection. Usefulness of XXXX .

@entity1 @entity8 @entity1904 @entity9409 @entity810 @entity2885 @entity221
OBJECTIVE: To establish the utility of @entity1904 (PCT) and other clinical and analytical parameters as markers of acute and permanent @entity8 in @entity1 after a first febrile urinary tract infection (UTI). METHODS: Retrospective multicentre study. Statistical study: descriptive, receiver operating characteristic (ROC) curves and multiple logistic regression. RESULTS: 219 @entity1 , aged between 1 week and 14 years (68% under 1 year). The mean PCT values were significantly higher in @entity1 with acute @entity2885 with respect to normal acute @entity9409 (4.8 vs 1.44; p=0.0001), without achieving that signification for late affected @entity9409 (6.5 vs 5.05; p=0.6). The area under the ROC curve for PCT was 0.64 (CI 95% 0.55-0.72) for @entity810 , and 0.62 (CI 95% 0.44-0.80) for permanent damage, with optimum statistical cut-off values of 0.85 and 1.17ng/ml. Multivariate analysis for @entity810 only found correlation with PCT (Odds Ratio [OR] 1.2 (CI 95% 1.06-1.4, p=0.005), and hours of @entity221 (OR for less than 6 hours of @entity221 0.4 (CI 95% 0.2-1.02, p=0.05). In @entity1 with @entity8 , PCT showed an OR 1.0 (CI 95% 0.9-1.1, p=0.6). CONCLUSIONS: PCT and the duration of @entity221 were the only parameters statistically associated with early @entity8 did not reach statistical significance.
