How well do serum sTREM-1 measurements prognosticate in septic shock?
The soluble triggering receptor expressed on myeloid cells (sTREM)-1 has emerged as a potentially useful biomarker for the diagnosis of sepsis. This study aimed to evaluate the prognostic utility of serum sTREM-1 in septic shock, in comparison with that of procalcitonin measurements. Thirty-one consecutive patients in a tertiary medical intensive care unit with septic shock were studied. sTREM-1 levels in blood were measured using a modified immunoblot array technique on days one to three of intensive care unit admission. ⋯ In contrast, procalcitonin levels were significantly higher in nonsurvivors than in survivors on days two and three. A significant relationship also existed between procalcitonin levels and the other variables. In conclusion, this study found that the prognostic utility of serum sTREM-1 in septic shock is poor and that procalcitonin measurements perform better in this regard.
