The relationship between the 28-day mortality and each component of the JAAM-DIC criteria (i.e., SIRS score, platelet count, FDP, and PT ratio) and the antithrombin activity at baseline (day of DIC diagnosis) were examined by univariate analysis in a logistic regression model. Variables associated with 28-day mortality at a P level of less than 0.05 were analyzed using a multivariate analysis (standard method of logistic regression analysis). The analysis was conducted using the outcome (survived, 0; died, 1) as the criterion variate and the SIRS score, platelet count, PT ratio, FDP, and antithrombin activity as explanatory variates. The differences in mortality according to various antithrombin activities were examined using the χ2 test.
The numerical values in the text and tables are the median and interquartile range (IQR), unless otherwise noted. The results of the logistic regression analysis were reported as the odds ratio (OR), P values, and 95 % confidence interval (CI). For all the reported results, P < 0.05 was considered to denote statistical significance. The above-mentioned analyses were performed using JMP software, version 9.0 (SAS Institute Co, Ltd, Cary, North Carolina).

For analysis of liver histopathology by light microscopy, formalin-fixed liver sections were cut at 5 microns and stained with hematoxylin and eosin (H&E) and sirius red by the Michigan State University Investigative Histopathology Laboratory. At least 2 sections of liver from the left lateral lobe of each animal were qualitatively evaluated in their entirety by a Board-certified veterinary pathologist (K.J.W.). Quantitative measures of necrosis (i.e., lesion frequency and size) in H&E-stained sections were performed in a masked fashion using ImageJ. For quantification of Sirius red staining (collagen deposits), images of Sirius-red stained liver sections were captured using a Virtual Slide System VS110 (Olympus, Hicksville, NY) with a 20X objective. Random images were derived from the digitized slides approximating at least 100 mm2 tissue for each liver. The area of positive sirius red staining in each image was determined in an unbiased fashion using a batch macro and the color deconvolution tool in ImageJ. Total bile acids in serum were determined using a colorimetric assay (Bio-Quant, San Diego, CA) and serum activities of alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were determined using commercial reagents (Thermo Scientific, Waltham, MA; Pointe Scientific, Canton, MI). Plasma thrombin-antithrombin (TAT) and serotonin levels were determined using commercial enzyme-linked immunosorbent assay kits (Siemens Healthcare Diagnostics, Deerfield, IL; Eagle Biosciences, Nashua, NH). Serum cytokine levels (IL-6, IL-4, KC/Gro, TNFα) were determined using the Meso Scale V-PLEX Proinflammatory Panel Kit and a Sector 600 Imager (Meso Scale Discovery, Rockville, MD).

A DE tablet (110mg, Pradaxa, Boehringer Ingelheim, Ingelheim, Germany) was dissolved with 1% dimethylsulfoxide (DMSO) in saline solution. Solutions with three different DE concentrations were prepared: 10mg/ml, 20mg/ml, and 30mg/ml. DE mice were fed three times orally using a gastric tube with intervals of eight hours. Each feeding consisted of 0.15mL of the respective solution resulting in a dose of 37.5mg/kg, 75mg/kg or 112.5mg/kg body weight per feeding for a 40g mouse. Oral gavages of comparable dosages of DE were previously shown to cause significant activated partial thromboplastin time (aPTT) prolongation in rats.16 (link) Control mice were fed three times with 0.15mL saline following the same modus of application. Determination of coagulation parameters or ICH induction by collagenase injection and laser-induced vessel rupture, respectively, was performed 0.5 hours after the last oral gavage of either DE or saline. In a subset of mice, multiple coagulation parameter analyses over time were performed, in order to determine the kinetics of DE anticoagulation. Furthermore, the effect of the solvent DMSO alone on coagulation parameters and ICH volume was determined.
Warfarin was applied via drinking water following a previously established protocol.4 (link), 15 (link) For mice with a body weight of 40g, a daily water consumption of 15mL/100g provided an estimated warfarin intake of 0.1mg (2.5mg/kg) within a 30 hour feeding period. Determination of coagulation parameters or ICH induction, respectively, was done at the end of the warfarin feeding period.
In addition, we treated mice with lepirudin (1.5mg/kg), heparin (80IU/kg), or fondaparinux (0.1mg/kg). Heparin inhibits thrombin indirectly by catalyzing its inactivation by antithrombin III. In addition, it inhibits factor Xa in complex with antithrombin III. As a selective factor Xa inhibitor, fondaparinux does not have direct effects on thrombin.17 (link) Each agent was dissolved in saline (total volume 0.1mL) and administered by a single retro-orbital i.v. injection, immediately followed by a single subcutaneous injection of the same dose and volume. These doses were chosen according to the literature.18 (link)-20 (link) Determination of coagulation parameters or ICH induction by collagenase injection, respectively, was done 0.5 hours after the subcutaneous application.
