title: [Prognostic value of the sTREM-1 plasma values in patients with sepsis: a cohort study].
abstract: OBJECTIVE
  To evaluate the association between plasma levels of soluble Triggering Receptor Expressed on Myeloid Cells-1 (sTREM-1) and mortality of patients with sepsis.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Two general Intensive Care Units.
  
  
  METHODS
  Patients with sepsis in whom sTREM-1 plasma levels were determined daily in the first 3 days of their presentation.
  
  
  METHODS
  Mortality at 28 days.
  
  
  RESULTS
  We analyzed 121 patients (23% severe sepsis, 44% septic shock, 33% non-severe sepsis). Mortality at 28 days was 24.8%. The initial sTREM-1 levels were slightly higher in nonsurvivors than in survivors (median 366.9 versus 266.5 pg/ml, p=0.2668). An increase in sTREM-1 levels higher than 90 pg/ml within the first 3 days (delta-TREM) was associated with an excess of mortality (hazard ratio [HR] 2.68, p=0.0047), with a sensitivity of 47% and a specificity of 78%. This excess of mortality disappeared after adjusting for severity by Cox analysis (adjusted HR 1.07, p=0.8665).
  
  
  CONCLUSIONS
  The increase in the levels of sTREM-1 during the first 3 days of evolution is associated with an excess of mortality in critically ill patients with sepsis. This is explained by the greater initial severity of these patients. The discriminative capacity of this finding is insufficient to be clinically useful.
