Abstract Abstract 3413 Background: Disseminated intravascular coagulation (DIC) is a lethal complication in patients with hematological malignancies. Although standard therapy against DIC remains to be established, soluble recombinant thrombomodulin (rTM), which serves as a receptor for thrombin, has been developed and its effectiveness for DIC was recently reported (Saito et al, J Thromb Haemost 2006). We retrospectively analyzed 55 DIC episodes treated with rTM in patients with hematological malignancies. Patients and Methods: 55 consecutive DIC episodes in 47 patients with hematological malignancies (AML except for APL, 21; APL, 8; ALL, 8; lymphoma, 8; myeloma, 2) hospitalized between November 2009 and July 2012 in University of Tsukuba Hospital were retrospectively analyzed. Diagnosis of DIC was based on DIC score of Japanese Ministry of Health and Labor Welfare criteria (Kobayashi et al, Bibl Haematol 1983). DIC was induced by hematological malignancy itself and severe infection secondary to hematological malignancy in 39 and 16 episodes, respectively. In every episode, 380 units/kg/day of rTM was administered intravenously from the onset of DIC for median of 7 (range, 2–22) days. The fibrin degradation products (FDP) level, DIC score, recovery time from DIC (recovery, the day when DIC score was decreased to 5 or less), and overall survival were analyzed. Results: Median DIC score at the onset was 7 (range, 6–11). 15 episodes were accompanied by bleeding tendency. Average of FDP level at the onset was 64.6 ƒÊg/dl (range, 20.6–202.4) in malignancy-induced DIC and 30.1 ƒÊg/dl (range, 13.2–72.0) in infection-induced DIC (P=0.03). FDP level 14 days after rTM administration was 10.1 ƒÊg/dl (SD: 3.7–27.9) and 20.3 ƒÊg/dl (SD: 9.3–44.3), respectively (P=0.04). Recovery rates from DIC 7 days after rTM administration were 72% in malignancy-induced DIC and 39% in infection-induced DIC (Fig. 1, P=0.02), and 100-day overall survival after the onset of DIC were 89% and 15% (Fig. 2, P<0.01), respectively. In multivariate analysis, infection-induced DIC was an only significant risk factor and presence of bleeding tendency, FDP level at the onset, DIC score at the onset, period of rTM administration, and number of rTM administration did not influence the recovery from DIC and overall survival. There were no severe hemorrhagic events after rTM administration or deterioration of bleeding tendency that led to discontinuation of rTM. Discussion and Conclusion: The recovery rate from hematological malignancy-induced DIC in the current cohort was comparable to that of rTM-treated DIC group (66%) and can be superior to that of heparin-treated DIC group (50%) in a previously reported phase III trial (Saito et al, J Thromb Haemost 2006). Although the use of heparin has fostered bleeding tendency in a number of previous DIC reports, bleeding tendency was reduced after rTM administration in all the DIC episodes analyzed with the current cohort. Therefore, this analysis traced the core conclusion of the previous phase III trial, emphasizing that rTM can be an effective anti-DIC agent without causing adverse hemorrhagic event even in DIC cases with preexisting bleeding tendency. However, the result was still significantly worse in infection-induced DIC secondary to hematological malignancies. Disclosures: Chiba: Asahi Kasei Pharma: Research Funding.

Coagulopathy commonly occurs in sepsis as a critical host response to infection that can progress to disseminated intravascular coagulation (DIC) with an increased mortality. Recent studies have further defined factors responsible for the thromboinflammatory response and intravascular thrombosis, including neutrophil extracellular traps, extracellular vesicles, damage-associated molecular patterns, and endothelial glycocalyx shedding. Diagnosing DIC facilitates sepsis management, and is associated with improved outcomes. Although the International Society on Thrombosis and Haemostasis (ISTH) has proposed criteria for diagnosing overt DIC, these criteria are not suitable for early detection. Accordingly, the ISTH DIC Scientific Standardization Committee has proposed a new category termed “sepsis-induced coagulopathy (SIC)” to facilitate earlier diagnosis of DIC and potentially more rapid interventions in these critically ill patients. Therapy of SIC includes both treatment of the underlying infection and correcting the coagulopathy, with most therapeutic approaches focusing on anticoagulant therapy. Recently, a phase III trial of recombinant thrombomodulin was performed in coagulopathic patients. Although the 28-day mortality was improved by 2.6% (absolute difference), it did not reach statistical significance. However, in patients who met entry criteria for SIC at baseline, the mortality difference was approximately 5% without increased risk of bleeding. In this review, we discuss current advances in managing SIC and DIC.
