Patterns of C-reactive protein ratio response to antibiotics in pediatric sepsis: A prospective cohort study.
Journal of Critical Care 2018 April
PURPOSE: Evaluate sequential C-reactive protein (CRP) measurements and patterns of CRP-ratio response to antibiotic therapy during first 7days in Pediatric Intensive Care Unit (PICU) of septic children.
METHODS: Prospective, cohort study of children (1month-12years) admitted at 3 PICUs, with diagnosis of sepsis with <72h course. CRP-ratio was calculated in relation to D0_CRP value. Children were classified according to an individual pattern of CRP-ratio response: fast - CRP_D4 of therapy was <0.4 of D0_CRP; slow - continuous but slow decrease of CRP; non - CRP remained ≥0.8 of D0_CRP; biphasic - initial CRP decrease to levels <0.8 of D0_CRP followed by secondary rise ≥0.8.
RESULTS: 103 septic children (age-median: 2yrs; 54% male) were prospectively included (infection focus: 65% respiratory, 12.5% central nervous system). Overall PICU mortality was 11.7%. 102 children could be classified according to a predefined CRP-ratio response pattern. Time-dependent analysis of CRP-ratio and CRP course of the different patterns were significantly different. Besides, PICU mortality rate was significantly different according CRP-ratio response patterns: fast response 4.5%; slow response 5.8%; non-response 29.4%; biphasic response 42.8%.
CONCLUSIONS: In pediatric sepsis, CRP-ratio serial evaluation was useful in early identification of patients with poor outcome.
