Abstract

AIM: To investigate posttraumatic cytokine alterations and their value for predicting complications and mortality in polytraumatized patients.

METHODS: Studies on the use of specific cytokines to predict the development of complications and mortality were identified in MEDLINE, EMBASE, Web of Science and the Cochrane Library. Of included studies, relevant data were extracted and study quality was scored.

RESULTS: Forty-two studies published between 1988 and 2015 were identified, including 28 cohort studies and 14 “nested” case-control studies. Most studies investigated the cytokines interleukin (IL)-6, IL-8, IL-10 and tumor necrosis factor (TNF-α). IL-6 seems related to muliorgan dysfunction syndrome, multiorgan failure (MOF) and mortality; IL-8 appears altered in acute respiratory distress syndrome, MOF and mortality; IL-10 alterations seem to precede sepsis and MOF; and TNF-α seems related to MOF.

CONCLUSION: Cytokine secretion patterns appear to be different for patients developing complications when compared to patients with uneventful posttraumatic course. More research is needed to strengthen the evidence for clinical relevance of these cytokines.

Keywords: Multiple trauma; Cytokine; Acute respiratory distress syndrome; Sepsis; Muli-organ dysfunction syndrome; Multi-organ failure

Core tip: Early identification of patients at risk for developing complications is one of the most challenging problems in the therapy of multiple injuries. Close monitoring of cytokine secretion patterns could give physicians an impression of the individual risk for development of complications. Further, physicians are directed to the appropriate prophylactic treatment, as well as optimal timing of surgical interventions, thereby reducing “second hits” with subsequent risks of development of sepsis and multiorgan failure. This article provides an overview of the results from literature concerning posttraumatic immune alterations leading to various complications and death.
