Organ dysfunction induced by sepsis has been consistently associated with worse outcome and death. Regardless of the organ compromised, epithelial dysfunction is present throughout the body, affecting those organs that contain epithelia like the skin, lungs, liver, gut, and kidneys. ⋯ Epithelial injury in this context is not only an explanatory real pathophysiologic event, but also represents a source of biomarkers that have been explored to identify organ compromise earlier, predict outcome, and even to test novel therapeutic interventions such as blood purification. However, this remains largely experimental, and despite promising results, work is still required to better understand the response of the epithelial cells to sepsis, to define their role in adaptation to insults, to comprehend the interorgan cross-talk that occurs in these circumstances, and to exploit these aspects in pursuit of targeted therapies like blood purification, which may improve outcome for these patients in the future.

Multicenter Study
HIGH D-DIMER LEVELS PREDICT A POOR OUTCOME IN PATIENTS WITH SEVERE TRAUMA, EVEN WITH HIGH FIBRINOGEN LEVELS ON ARRIVAL: A MULTICENTER RETROSPECTIVE STUDY.
Elevated D-dimer level in trauma patients is associated with tissue damage severity and is an indicator of hyperfibrinolysis during the early phase of trauma. To investigate the interacting effects of fibrinogen and D-dimer levels on arrival at the emergency department for massive transfusion and mortality in severe trauma patients in a multicenter retrospective study. This study included 519 adult trauma patients with an injury severity score ≥16. ⋯ The survival rate was lower in the high D-dimer/low fibrinogen group than in the other groups. Moreover, the survival rate was lower in the high D-dimer/high fibrinogen group than in the low D-dimer/high fibrinogen and low D-dimer/low fibrinogen groups. High D-dimer level on arrival is a strong predictor of early death or requirement for massive transfusion in severe trauma patients, even with high fibrinogen levels.
