Early thrombomodulin-α administration outcome for acute disseminated intravascular coagulopathy in gastrointestinal...

To investigate the efficacy of thrombomodulin (TM)-α for treatment of disseminated intravascular coagulopathy (DIC) in the field of gastrointestinal surgery.

Thirty-six peri-operative DIC patients in the field of gastrointestinal surgery who were treated with TM-α were retrospectively investigated. The relationships between patient demographics and the efficacy of TM-α were examined. Analysis of survival at 28 d was also performed on some parameters by means of the Kaplan-Meier method. Relationships between the initiation of TM-α and patient demographics were also evaluated.

Abscess formation or bacteremia was the most frequent cause of DIC (33%), followed by digestive tract perforation (31%). Twenty-six patients developed DIC after surgery, frequently within 1 wk (81%). TM-α was most often administered within 1 d of the DIC diagnosis (72%) and was continued for more than 3 d (64%). Although bleeding tendency was observed in 7 patients (19%), a hemostatic procedure was not needed. DIC scores, systemic inflammatory response syndrome (SIRS) scores, quick-sequential organ failure assessment (qSOFA) scores, platelet counts, and prothrombin time ratios significantly improved after 1 wk (P < 0.05, for all). The overall survival rate at 28 d was 71%. The duration of TM-α administration (≥ 4 , ≤ 6) and improvements in DIC-associated scores (DIC, SIRS and qSOFA) at 1 wk were significantly better prognostic factors for 28-d survival (P < 0.05, for all). TM-α was administered significantly earlier to patients with severe clinical symptoms, such as high qSOFA scores, sepsis, shock or high lactate values (P < 0.05, for all).

Early administration of TM-α and improvements in each parameter were essential for treatment of DIC. The diagnosis of patients with mild symptoms requires further study.
