Background:
Respiratory dysfunction associated with severe sepsis is a serious condition leading to poor prognosis. Activation of coagulation is a consequence of and contributor to ongoing lung injury in severe sepsis. The purpose of this study was to examine the efficacy of recombinant human soluble thrombomodulin (rhTM), a novel anticoagulant agent, for treating patients with sepsis-induced disseminated intravascular coagulation (DIC) in terms of mortality and respiratory dysfunction.
Methods:
This study comprised 86 consecutive patients with sepsis-induced DIC who required ventilator management. The initial 45 patients were treated without rhTM (control group), and the following 41 patients were given rhTM (0.06 mg/kg/d) for 6 days (rhTM group). Patients were followed up for 90 days after study entry. Sequential Organ Failure Assessment (SOFA) score and lung injury score were recorded until 7 days after entry.
Results:
The baseline characteristic of severity of illness was significantly higher in the rhTM group than in the control group. Nevertheless, 90-day mortality rate in the rhTM group was significantly lower than that in the control group (37% vs. 58%, p = 0.038). There was a significant difference in the serial change of SOFA score from baseline to day 7 between the two groups (p = 0.009). Both the respiratory component of the SOFA score and the lung injury score in the rhTM group were significantly lower compared with the control group (p = 0.034 and p < 0.001, respectively).
Conclusions:
rhTM may have a significant beneficial effect on mortality and respiratory dysfunction in patients with sepsis-induced DIC.
Level Of Evidence:
III, therapeutic study.
