Abstract Background: Cell-free DNA concentrations increase in the circulation of patients after trauma and may have prognostic potential, but little is know concerning the temporal changes or clearance of the DNA or its relationships with posttraumatic complications. We investigated temporal changes in plasma DNA concentrations in patients after trauma with use of real-time quantitative PCR. Methods: Serial plasma samples were taken from two trauma populations. In the first study, samples were collected every 20 min from 25 patients within the first 3 h of trauma. In the second study, samples were collected every day from 36 other trauma patients admitted to the intensive care unit (ICU). Results: In the first study, plasma DNA was increased within 20 min of injury and was significantly higher in patients with severe injury and in patients who went on to develop organ failure. In patients with less severe injuries, plasma DNA concentrations decreased toward reference values within 3 h. In the second study, plasma DNA concentrations were higher in patients who developed multiple organ dysfunction syndrome between the second and fourth days of admission than in patients who did not develop the syndrome. In patients who remained in the ICU with continuing organ dysfunction, plasma DNA remained higher than in healthy controls even at 28 days after injury. Most survivors with multiple organ dysfunction syndrome showed an initial very high peak followed by a prolonged smaller increase. Conclusions: Plasma DNA concentrations increase early after injury and are higher in patients with severe injuries and in those who develop organ failure. Increased plasma DNA persists for days after injuries, especially in patients with multiple organ dysfunction syndrome.

Ultimate Outcome

The concept of and approach to multiple organ dysfunction syndrome (MODS), also known as progressive systems failure, multiple organ failure, and multiple system organ failure, have evolved over the last decade. Characterized by progressive but potentially reversible tissue damage and dysfunction of two or more organ systems that arise after a significant physiologic insult and its subsequent management, MODS evolves in the wake of a profound disruption of systemic homeostasis. Pre-existing illness, nutritional status, hospital course, and genetic variation all lead to the development of organ dysfunction in patients exposed to these risk factors. The ultimate outcome from MODS is influenced not only by a patient’s genetic and biological predisposition but also by specific management principles practiced by intensivists. This review details the clinical definitions, quantification, prevention, evaluation, support, and outcomes of organ dysfunction. A figure shows the increasing severity of organ dysfunction correlated with increasing intensive care unit mortality, and an algorithm details the approach to MODS. Tables list risk factors and prognosis for MODS, the multiple organ dysfunction (MOD) score, the sequential organ failure assessment (SOFA) score, intensive care unit interventions that reduce mortality or attenuate organ dysfunction along with unproven or disproven ICU interventions, and the temporal evolution of MODS. This review contains 1 figure, 7 tables, and 159 references.
