Background:
Patients with chronic alcohol abuse constitute approximately 50% of trauma care patients, and these patients have a two- to fourfold increase in posttraumatic infectious complications. Cytokines such as interleukin-6 (IL-6) and interleukin-10 (IL-10) and the adhesion molecule soluble endothelial selectin (sE-selectin) have been found to play an important role in the initial inflammatory response to trauma and the development of early and late multiple organ dysfunction syndrome (MODS). The aim of this study was to compare the immune modulation and clinical relevance between chronic alcoholic and nonalcoholic patients following trauma.
Methods:
Sixty-three patients (37 alcohol abusers, 26 nonalcoholics) were included in this prospective controlled study. IL-6, IL-10, and sE-selectin were determined on admission and on days 2, 4, and 7 following admission to the ICU.
Results:
On admission to the ICU but not on the following days of the study period, plasma IL-6, IL-10, and sE-selectin were significantly elevated in chronic alcoholic patients compared with nonalcoholics. The incidence of MODS was significantly higher in chronic alcoholic patients (89% vs. 50%, p < 0.01), whereas the incidence of pneumonia (35% vs. 19%, p < 0.17) and sepsis (14% vs. 0%, p < 0.07) did not reach statistical significance.
Conclusion:
The significantly elevated levels of IL-6, IL-10, and sE-selectin in chronic alcoholic trauma patients on admission to the ICU could play an important role in the development of MODS in intensive care. In patients with high levels of inflammatory mediators, immune modulatory treatment before the development of MODS may be considered.
