E.2.2 | Secondary objectives of the trial |
To evaluate diferences in: - clinical variables (hospitalization time, fever hours, recurrence % within 6 months after diagnosis) - inflamatory variables (urinary IL6 and IL8, serum procalcitonin and CRP at admision) - radiologic variables (determined by DMSA after 6 months of diagnosis)
between control and intervention group.
- To determine predictive factors for permanent renal damage. - To evaluate the intervention effect on high riks subgroups (i.e. vesiculouretral reflux). |
Evaluar las diferencias : - clínicas (tiempo de hospitalización, horas de fiebre, % de recurrencia en 6 meses tras el diagnóstico). - inflamatorias (IL6 y IL8 en orina, procalcitonina y PCR en suero al ingreso) - radiológicas (mediante DSMA a los 6 meses del primer episodio de ITU febril)
entre el grupo de control y de intervención
- Determinar factores predictivos de daño renal permanente. ? Valorar el efecto de la intervención sobre subgrupos de riesgo elevado (reflujo vesicoureteral). |
