Kinetics of C-reactive protein, interleukin-6 and -10, and phospholipase A2-II in severely traumatized septic patients.
OBJECTIVE
Injury-induced anergy is one of the key factors contributing to trauma victims' high susceptibility to sepsis. This group of patients is mostly of young age and it is therefore essential to be able to predict as accurately as possible the development of septic complications, so appropriate treatment could be provided. The aim of this study was to assess kinetics of interleukin (IL)-6 and -10, phospholipase A2-II and C-reactive protein (CRP) in severely traumatized patients and explore the possibilities for early detection of potentially septic patients.


METHODS
This prospective study included 65 traumatized patients with injury severity score (ISS) > 18, requiring treatment at surgical intensive care units, divided into two groups: 24 patients without sepsis and 41 patients with sepsis. C-reactive protein, IL-6 and -10 and phospholipase A2 group II, were determined within the first 24 hours, and on the second, third and seventh day of hospitalization.


RESULTS
Mean values of IL-6 and phospholipase A2-II in the patients with and without sepsis did not show a statistically significant difference on any assessed time points. In the septic patients with ISS 29-35 and > 35 on the days two and seven a statistically significantly lower level of IL-10 was found, compared with those without sepsis and with the same ISS. C-reactive protein levels were significantly higher in septic patients with ISS 18-28 on the first day. On the second, third and seventh day CRP levels were significantly lower in the groups of septic patients with ISS 29-35 and > 35, than in those with the same ISS but without sepsis.


CONCLUSIONS
Mean levels of CRP on the first day after the injury may be useful predictor of sepsis development in traumatized patients with ISS score 18-28. Mean levels of CRP on the days two, three and seven after the injury may be a useful predictor of sepsis development in traumatized patients with ISS score more than 28. Mean levels of IL-10 on the second and seventh day after the injury may be a useful predictor of sepsis development in traumatized patients with ISS score > 28.
