Plasma soluble thrombomodulin levels are associated with mortality in the acute respiratory distress syndrome.

ABSTRACT:

Objective

Thombomodulin (TM) is an activator of protein C and a biomarker for endothelial injury. We hypothesized that (1) elevated plasma levels would be associated with clinical outcomes and (2) polymorphisms in the TM gene would be associated with plasma levels.

Patients

We studied 449 patients enrolled in the Fluid and Catheter Treatment Trial (FACTT) for whom both plasma and DNA were available. We used logistic regression and receiver operator curves (ROC) to test for associations between soluble TM (sTM) and mortality at 60 days.

Measurements and results

Plasma sTM levels were higher in non-survivors than survivors at baseline [median 147 (IQR, 95-218) vs. 89 (56-129) ng/mL, p < 0.0001] and on day 3 after study enrollment [205 (146-302) vs. 127 (85-189), p < 0.0
