To establish the relation between routine laboratory data (lactate, fibrinogen, CRP) and cytokines (TNF,IL-1 and-6) and to estimate their prognostic value in pediatric patients with severe infectious purpura on admission.
Pediatric intensive care unit (PICU).
17 children aged 5–172 months (median 46) were hospitalized in our PICU in 1989–90 with severe infectious purpura.Neisseria meningitidis was isolated in 15 children andHaemophilus influenzae in two. The patients were divided into 3 groups: non-shock, shock and severe shock leading to death. Shock was defined by standard criteria.
Arterial blood was sampled for lactate, CRP, fibrinogen, TNF, and IL-1 and-6 on admission. The PRISM (pediatric risk of morality)-score was recorded.
Statistical analysis was performed with the Student'st-test using the logarithmic values of the cytokine concentration, and Spearman correlation analysis.
According to the shock criteria, 9 patients were in shock of whom 4 did not survive. Significant differences existed between the 3 groups concerning lactate, TNF, and IL-6. Fibrinogen, CRP, IL-1, and PRISM-score discriminated only between survivors and non-survivors. A highly significant correlation existed between cytokines, the PRISM-score and lactate (TNF:r=0.69, IL-1:r=0.56, IL-6:r=0.65, PRISM:r=0.65). A significant inverse correlation existed between cytokines and CRP (TNF:r=−0.55, IL-1:r=−0.64, and IL-6:r=−0.56), and IL-6 and fibrinogen (r=−0.65).
These results show a significant correlation between cytokines and lactate, and lactate, TNF and IL-6 are closely associated with the severity of septic shock with purpura in children.
