Actually, we previously reported that a dose of 125 IU/kg of AT enabled recovery to a value with the normal range and revealed the additive effects of AT and danaparoid sodium [18].The effects of rhsTM on DIC were previously examined in a multi-center RCT, compound libraries and the resolution of DIC was significantly better in the group treated with rhsTM than in the group treated with unfractionated heparin [11]. As the patients with resolved DIC had a lower mortality rate in this RCT, the correction of the coagulation abnormalities was suggested to lead to improved survival. In addition, other experiments reported that the effects of rhsTM were not only limited to DIC but that beneficial effects were also obtained against severe sepsis and other inflammatory responses [19,20].

Therefore, a clinical trial to determine the effects of rhsTM on severe sepsis is now underway.AT was expected to have favorable effects against severe sepsis, but it was denied in a large-scale multi-center RCT [11]. However, as a subgroup analysis reported beneficial effects in septic DIC patients [13], Hoffmann and colleagues [14] performed a small-sized RCT with an enrollment of 40 patients. This study demonstrated a better maintenance of haemostatic markers such as prothrombin time and fibrinogen level.The mortality rate for severe sepsis is still high and a single drug may be inadequate to obtain a favorable outcome [21]; therefore, we planned to examine the effects of the concomitant use of AT and rhsTM. Theoretically, the combination of AT and rhsTM could possibly exert additive or synergistic effects because the anticoagulant mechanisms differ for these agents.

As a result, the changes of platelet count and the fibrinogen levels were suppressed significantly only in the AT/TM group. However, as for the improvement in the organ dysfunction markers, there was no statistically significant difference in the ALT or LDH levels between AT and AT/TM group in this study. As for why we could not see the additive effects, we speculate that because AT alone had already suppressed the elevation of LDH significantly, and the effects of rhsTM might be concealed.With respect to the survival, it was better maintained in the AT/TM group compared with that in the control group. However, the significant difference was not seen between the AT group and AT/TM group, or rhsTM group and AT/TM group.

The mechanism of action responsible for these effects was not fully elucidated; however, other than the maintenance of coagulation disorders, the exertion of anti-inflammatory effects may contribute to the end result. To address this issue, the changes in the HMGB1 level were examined. HMGB1 is an intranuclear protein that was originally identified as a DNA-binding protein, [22], but has Dacomitinib been recognized as a late-phase mediator during sepsis [23].
