Abstract
OBJECTIVES Antithrombin is a cofactor in the coagulation cascade with mild anticoagulant activity and facilitates the action of heparin as an anticoagulant. Antithrombin concentrate dosing guidelines vary but most commonly suggest that each unit of antithrombin concentrate per body weight increases the plasma antithrombin level by 1.5% to 2.2% (depending on manufacturer). We aimed to establish a dosing recommendation dependent on age and disease state. DESIGN A retrospective analysis of all antithrombin concentrate doses over a period of 5 years. We calculated the increase any respective antithrombin concentrate dose achieved, indexed by body weight, and performed a multivariable analysis to establish independent factors associated with the effectiveness of antithrombin concentrate. SETTING A PICU at a university-affiliated children's hospital. PATIENTS One hundred fifty-five patients treated in a PICU. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The effect of 562 doses of antithrombin concentrate on plasma antithrombin levels administered to 155 patients, of which 414 (73.7%) antithrombin concentrate doses administered during extracorporeal life support treatment, were analyzed. For all patients, each unit of antithrombin concentrate/kg increased plasma antithrombin level by 0.86% (SD 0.47%). Plasma antithrombin level increase was influenced by body weight (increase of 0.76% [interquartile range, 0.6-0.92%] for patients < 5 kg; 1.38% [interquartile range, 1.11-2.10%] for > 20 kg), disease state (liver failure having the poorest antithrombin increase) and whether patients were treated with extracorporeal circulatory support (less antithrombin increase on extracorporeal life support). Heparin dose at the time of administration did not influence with amount of change in antithrombin level. CONCLUSIONS Current antithrombin concentrate dosing guidelines overestimate the effect on plasma antithrombin level in critically ill children. Current recommendations result in under-dosing of antithrombin concentrate administration. Age, disease state, and extracorporeal life support should be taken into consideration when administering antithrombin concentrate.

Abstract
Background Coagulopathy in traumatic brain injury (TBI) has been associated with poor neurological outcomes and higher in-hospital mortality. In general principle of trauma management, hypothermia should be prevented as it directly worsens coagulopathy. Therefore, we examined the safety of mild therapeutic hypothermia (MTH) in patients with coagulopathy following severe TBI. Methods We re-evaluated the brain hypothermia (B-HYPO) study data based on coagulopathy and compared the Glasgow Outcome Scale scores and survival rates at 6 months using per protocol analyses. Coagulopathy was defined as an activated partial thromboplastin time (APTT) > 60 s and/or fibrin/fibrinogen degradation product levels (FDP) > 90 μg/mL on admission. Baseline characteristics, coagulation parameters, and outcomes were compared between the control and MTH groups with or without coagulopathy. Results In patients with coagulopathy, 12 patients were allocated to the control group (35.5–37.0 °C) and 20 patients to the MTH group (32–34 °C). In patients without coagulopathy, 28 were allocated to the control group and 59 patients were allocated to the MTH group. In patients with coagulopathy, favorable neurological outcomes and survival rates were comparable between the control and MTH groups (33.3% vs. 35.0%, P = 1.00; 50.0% vs. 60.0%, P = 0.72) with no difference in complication rates. On admission, no significant differences in APTT or FDP levels were observed between the two groups; however, APTT was significantly prolonged in the MTH group compared to the control group on day 3. Discussion Based on our study, MTH did not seem to negatively affect the outcomes in patients with coagulopathy following severe TBI on admission; therefore, the present study indicates that MTH may be applicable even in patients with severe TBI and coagulopathy. Conclusions Our study suggests that in comparison to control, MTH does not worsen the outcome of patients with coagulopathy following severe TBI.

Abstract
INTRODUCTION The aim of this study was to evaluate the efficacy and complications of recombinant antithrombin (rAT) supplementation for adult patients with disseminated intravascular coagulation (DIC) compared with conventional plasma derived AT (pAT) treatment in the intensive care unit. MATERIALS AND METHODS This study was performed in a single national university hospital in Japan. Adult patients from April 2015 to March 2016 with DIC were divided into two groups based on the type of AT agent used: the pAT group (n=24) and the rAT group (n=21). Patient demographics, medical history, diagnosis, blood tests, various clinical scores, AT activity, complications, and clinical outcome were collected and analyzed retrospectively. RESULTS Significantly higher SIRS and APACHEII scores were confirmed in the rAT group than the pAT group. The initial dose of AT was significantly higher in the rAT group than in the pAT group. ATIII values before and after initial supplementation and during their ten-day clinical course were statistically similar between two groups. During the same period, 10 bleeding adverse events were found and there was no significant difference between both groups. Significantly more cases of the rAT group were administered with recombinant thrombomodulin concomitantly than those of the pAT group. Despite significantly more severe patients in rAT group, the clinical outcomes were the same in each group. CONCLUSIONS Compared with pAT, the supplementation of rAT indicates clinical effectiveness without increasing the risk of bleeding complications in adult DIC patients with low AT activity.

Abstract
BACKGROUND Critical illness is associated with uncontrolled inflammation and vascular damage which can result in multiple organ failure and death. Antithrombin III (AT III) is an anticoagulant with anti-inflammatory properties but the efficacy and any harmful effects of AT III supplementation in critically ill patients are unknown. This review was published in 2008 and updated in 2015. OBJECTIVES To examine:1. The effect of AT III on mortality in critically ill participants.2. The benefits and harms of AT III.We investigated complications specific and not specific to the trial intervention, bleeding events, the effect on sepsis and disseminated intravascular coagulation (DIC) and the length of stay in the intensive care unit (ICU) and in hospital in general. SEARCH METHODS We searched the following databases from inception to 27 August 2015: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid SP), EMBASE (Ovid SP,), CAB, BIOSIS and CINAHL. We contacted the main authors of trials to ask for any missed, unreported or ongoing trials. SELECTION CRITERIA We included randomized controlled trials (RCTs) irrespective of publication status, date of publication, blinding status, outcomes published, or language. We contacted the investigators and the trial authors in order to retrieve missing data. In this updated review we include trials only published as abstracts. DATA COLLECTION AND ANALYSIS Our primary outcome measure was mortality. Two authors each independently abstracted data and resolved any disagreements by discussion. We presented pooled estimates of the intervention effects on dichotomous outcomes as risk ratios (RR) with 95% confidence intervals (CI). We performed subgroup analyses to assess risk of bias, the effect of AT III in different populations (sepsis, trauma, obstetrics, and paediatrics), and the effect of AT III in patients with or without the use of concomitant heparin. We assessed the adequacy of the available number of participants and performed trial sequential analysis (TSA) to establish the implications for further research. MAIN RESULTS We included 30 RCTs with a total of 3933 participants (3882 in the primary outcome analyses).Combining all trials, regardless of bias, showed no statistically significant effect of AT III on mortality with a RR of 0.95 (95% CI 0.88 to 1.03), I² statistic = 0%, fixed-effect model, 29 trials, 3882 participants, moderate quality of evidence). For trials with low risk of bias the RR was 0.96 (95% Cl 0.88 to 1.04, I² statistic = 0%, fixed-effect model, 9 trials, 2915 participants) and for high risk of bias RR 0.94 (95% Cl 0.77 to 1.14, I² statistic = 0%, fixed-effect model, 20 trials, 967 participants).For participants with severe sepsis and DIC the RR for mortality was non-significant, 0.95 (95% Cl 0.88 to 1.03, I² statistic = 0%, fixed-effect model, 12 trials, 2858 participants, moderate quality of evidence).We conducted 14 subgroup and sensitivity analyses with respect to the different domains of risk of bias, but detected no statistically significant benefit in any subgroup analyses.Our secondary objective was to assess the benefits and harms of AT III. For complications specific to the trial intervention the RR was 1.26 (95% Cl 0.83 to 1.92, I² statistic = 0%, random-effect model, 3 trials, 2454 participants, very low quality of evidence). For complications not specific to the trial intervention, the RR was 0.71 (95% Cl 0.08 to 6.11, I² statistic = 28%, random-effects model, 2 trials, 65 participants, very low quality of evidence). For complications other than bleeding, the RR was 0.72 ( 95% Cl 0.42 to 1.25, I² statistic = 0%, fixed-effect model, 3 trials, 187 participants, very low quality of evidence). Eleven trials investigated bleeding events and we found a statistically significant increase, RR 1.58 (95% CI 1.35 to 1.84, I² statistic = 0%, fixed-effect model, 11 trials, 3019 participants, moderate quality of evidence) in the AT III group. The amount of red blood cells administered had a mean difference (MD) of 138.49 (95% Cl -391.35 to 668.34, I² statistic = 84%, random-effect model, 4 trials, 137 participants, very low quality of evidence). The effect of AT III in patients with multiple organ failure (MOF) was a MD of -1.24 (95% Cl -2.18 to -0.29, I² statistic = 48%, random-effects model, 3 trials, 156 participants, very low quality of evidence) and for patients with an Acute Physiology and Chronic Health Evaluation score (APACHE) at II and III the MD was -2.18 (95% Cl -4.36 to -0.00, I² statistic = 0%, fixed-effect model, 3 trials, 102 participants, very low quality of evidence). The incidence of respiratory failure had a RR of 0.93 (95% Cl 0.76 to 1.14, I² statistic = 32%, random-effects model, 6 trials, 2591 participants, moderate quality of evidence). AT III had no statistically significant impact on the duration of mechanical ventilation (MD 2.20 days, 95% Cl -1.21 to 5.60, I² statistic = 0%, fixed-effect model, 3 trials, 190 participants, very low quality of evidence); on the length of stay in the ICU (MD 0.24, 95% Cl -1.34 to 1.83, I² statistic = 0%, fixed-effect model, 7 trials, 376 participants, very low quality of evidence) or on the length of stay in hospital in general (MD 1.10, 95% Cl -7.16 to 9.36), I² statistic = 74%, 4 trials, 202 participants, very low quality of evidence). AUTHORS' CONCLUSIONS There is insufficient evidence to support AT III substitution in any category of critically ill participants including the subset of patients with sepsis and DIC. We did not find a statistically significant effect of AT III on mortality, but AT III increased the risk of bleeding events. Subgroup analyses performed according to duration of intervention, length of follow-up, different patient groups, and use of adjuvant heparin did not show differences in the estimates of intervention effects. The majority of included trials were at high risk of bias (GRADE; very low quality of evidence for most of the analyses). Hence a large RCT of AT III is needed, without adjuvant heparin among critically ill patients such as those with severe sepsis and DIC, with prespecified inclusion criteria and good bias protection.

Abstract
Antithrombin III (ATIII) of low doses (1500-3000 units per day for 3-5 days) has been used for treatment of disseminated intravascular coagulation (DIC) for decades in Japan. In this study, we have examined the impact of ATIII practice change on outcome in critically ill patients with sepsis and DIC. From April 2005 to September 2008, all septic patients admitted to our ICU were divided into two groups: before withdrawing ATIII (period 1) and after withdrawing ATIII (period 2). Patients treated with ATIII in the period 1 and those not treated with ATIII in the period 2 were then matched according to the similar Acute Physiology and Chronic Health Evaluation II scores (± 3) and the same diagnosis grouping. Sensitivity analysis was also conducted for patients with DIC. Forty-one out of 98 patients (41.8%) in the period 1 and only one out of 80 patients (1.3%) in the period 2 were treated with ATIII. Thirty pairs of the patients were matched. There was no difference between the two groups regarding the platelet counts and Sepsis-related Organ Failure Assessment scores at day 1 and day 4. A subgroup analysis was conducted with 12 patients diagnosed with DIC out of the 30 pairs. There was no difference between the two DIC groups for platelet counts, Sepsis-related organ failure assessment scores and DIC score at day 1 and also day 4. Although not significant, hospital mortality tended lower in the period 2. This study found that withdrawing ATIII administration from management of septic patients with or without DIC did not influence outcome.

Abstract
BACKGROUND Disseminated intravascular coagulation (DIC) is an acquired syndrome characterized by systemic intravascular activation of coagulation, leading to deposition of fibrin in the bloodstream. It may occur in patients with acute and chronic leukemia and is particularly associated with acute promyelocytic leukemia (a subtype of acute myeloid leukemia). OBJECTIVES To assess the clinical benefits and harms of any pharmacological intervention for treating DIC in patients with acute or chronic leukemia. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2015, Issue 05), MEDLINE (1946 to 7 May 2015), LILACS (1982 to 7 May 2015) and African Index Medicus (7 May 2015). There was no language restrictions. We sought additional randomized controlled trials (RCTs) from the World Health Organization International Clinical Trials Registry Platform and the reference lists of primary studies identified. SELECTION CRITERIA RCTs assessing the clinical benefits and harms of interventions for treating DIC in patients with acute and chronic leukemia. DATA COLLECTION AND ANALYSIS Two review authors independently performed trial selection, 'Risk of bias' assessment and data extraction. Primary outcomes were overall mortality, in-hospital mortality from any cause (15-day and 30-day) and adverse events. MAIN RESULTS In this Cochrane Review update we did not include any new RCT compared with the first review version. Accordingly, four RCTs (388 participants) met the inclusion criteria. These trials evaluated the human activated protein C, recombinant human soluble thrombomodulin, tranexamic acid and dermatan sulphate. Included trials reported data on mortality and bleeding. The studies were conducted in Japan, Italy and the Netherlands. We classified the included trials as: 1) including patients with or without leukemia which did not report data for the leukemia subgroup (366 participants); and 2) only including patients with leukemia (22 participants). Overall, the risk of bias of the included trials was high, since the trial authors did not provide a detailed description about trial design and execution.According to the GRADE recommendations, we judged the overall quality of the body of evidence for all prefixed outcomes as 'very low', due to methodological limitations and very small sample size.One trial, including 10 participants with leukemia and comparing dermatan sulphate with heparin, reported no deaths during trial treatment.In terms of bleeding data, we were unable to pool results from two studies that were only conducted with leukemia patients due to the inconsistency in the measurement and reporting of this outcome. One trial, including 12 participants with leukemia, found very low quality evidence that tranexamic acid can reduce the cumulative hemorrhagic score in participants compared with those assigned to placebo (P = 0.0015, very low quality evidence). On the contrary, there is no evidence that dermatan sulphate compared with placebo reduces new events of hemorrhagic diathesis (1/5 (20%) versus 2/5 (40%); RR 0.50; 95% CI 0.06 to 3.91; P = 0.51, very low quality evidence).No thromboembolic complications were reported in either trial that included patients with leukemia only (very low quality evidence). The safety profile was inconclusive.The included trials did not assess overall mortality, resolution of respiratory failure, renal failure or shock. AUTHORS' CONCLUSIONS Due to a lack of new RCTs, our conclusions in this Cochrane Review update are the same as the previous review version. We included four RCTs which reported mortality and bleeding data. It is not possible to determine whether human activated protein C, recombinant human soluble thrombomodulin, tranexamic acid and dermatan sulphate are effective or harmful for patients presenting with DIC related to acute or chronic leukemia. The quality of the evidence was low to very low. Therefore, prescription of these interventions for treating DIC in patients with acute and chronic leukemia can neither be supported nor rejected, unless new evidence from a large high-quality trial alters this conclusion.

Abstract
BACKGROUND There have been no studies comparing the effects of antithrombin (AT-III) and recombinant human soluble thrombomodulin (rhs-TM) on outcomes in patients with disseminated intravascular coagulation (DIC) associated with infectious diseases. OBJECTIVE The aim of this observational study is to compare AT-III and rhs-TM in terms of outcomes such as mortality, length of hospitalization, and medical costs in patients with DIC associated with infectious diseases based on a Japanese administrative database. SETTING A total of 7,535 patients with DIC associated with infectious diseases in 886 hospitals from 2010 to 2012 in Japan. Methods We collected patients' data from the administrative database to compare clinical and medical economic outcomes of patients with DIC. Patients were divided into two groups according to treatment of DIC: AT-III (n = 3,601) and rhs-TM (n = 3,934). MAIN OUTCOMES MEASURE In-hospital mortality (within 14 days, within 28 days, and overall mortality), length of stay (LOS), and medical costs during hospitalization. RESULTS Multilevel logistic regression analysis showed that there were no significant differences with regard to in-hospital mortality between AT-III and rhs-TM within 14 days (odds ratio (OR) of rhs-TM 0.97, 95 % confidence interval (CI) 0.85-1.11, p = 0.744), within 28 days (OR 1.00, 95 % CI 0.89-1.13, p = 0.919), and overall (OR 0.95, 95 % CI 0.85-1.07, p = 0.470). However, multilevel linear regression analysis revealed that use of rhs-TM significantly decreased LOS and medical costs during hospitalization. The coefficient for LOS was -2.92 days (95 % CI -4.79 to -1.04 days; p = 0.002) whereas that for medical costs during hospitalization was -798.3 Euro (95 % CI -1,515.7 to -81.0 Euro; p = 0.029). CONCLUSION This study demonstrated no significant difference in in-hospital mortality between AT-III and rhs-TM. However, use of rhs-TM was significantly associated with decreased LOS and medical costs during hospitalization in patients with DIC associated with infectious diseases.

Abstract
Introduction In a previous report, we demonstrated a favorable trend for supplementation with antithrombin (AT) concentrate at a dosage of 3,000 IU/day over 1,500 IU/day for the treatment of sepsis-associated disseminated intravascular coagulation (DIC) in patients with an AT activity of 70% or less. Since the survival difference did not reach statistical significance, we planned to examine the effects in a larger number of cases with severer disease. Methods We performed a non-randomized multi-institutional survey. In total, 307 septic DIC patients who had AT activity less than 40% and who had undergone AT substitution at a dose of either 1,500 IU/day or 3,000 IU/day for three consecutive days were analyzed. Of these, 259 patients received 1,500 IU/day (AT1500 group) and 48 patients received 3,000 IU/day (AT3000 group). The primary efficacy endpoints were recovery from DIC by day 7 and an all-cause mortality on day 28. Adverse bleeding events were also examined. A logistic regression analysis was conducted by using age, sex, body weight, initial AT activity, DIC score, platelet count, coadministration of heparin, recombinant thrombomodulin, suspected source of infection, surgery, and supplemented AT dose. Results Supplementation significantly decreased the DIC score in the AT3000 group, leading to the superior resolution of DIC, compared with the results in the AT1500 group (66.7% versus 45.2%, P = 0.007). In addition, the AT3000 group exhibited a better survival than the AT1500 group (77.1% versus 56.4%, P = 0.010). Bleeding events were observed in 6.96% (severe bleeding: 3.04%) in the AT1500 group and 6.52% (severe bleeding, 4.35%) in the AT3000 group (P = 1.000; severe bleeding, P = 0.648). A logistic regression analysis revealed that the use of AT3000 (odds ratio (OR), 2.419; P = 0.025), a higher initial platelet count (OR, 1.054; P = 0.027), and patient age (OR, 0.977; P = 0.045) were significantly correlated with an improved survival. Conclusions The AT3000 group exhibited significantly improved rates of survival and recovery from DIC without an increased risk of bleeding, compared with the AT1500 group, among the patients with sepsis-associated DIC and an AT activity of less than 40%.

Abstract
BACKGROUND Dysfunctional natural anticoagulant systems enhance intravascular fibrin formation in disseminated intravascular coagulation (DIC), and plasma levels of natural anti coagulants can be used in the diagnosis and prognosis of DIC. Herein, the diagnostic value of 4 natural anticoagulants was assessed, and the prognostic value of antithrombin and protein C were validated in a large population. METHODS Part 1 study included 126 patients with clinically suspected DIC and estimated plasma levels of 4 candidate anticoagulant proteins: antithrombin, protein C, protein S, and protein Z. Part 2 comprised 1,846 patients, in whom plasma antithrombin and protein C levels were compared with other well-known DIC markers according to the underlying dis eases. The 28-day mortality rate was used to assess prognostic outcome. RESULTS Antithrombin and protein C showed higher areas under the ROC curve than protein S and protein Z. In part 2 of the study, antithrombin and protein C levels significantly correlated with DIC score, suggesting that these factors are good indicators of DIC severity. Antithrombin and protein C showed significant prognostic power in Kaplan-Meier analyses. In patients with sepsis/severe infection, antithrombin and protein C showed higher hazard ratios than D-dimer. Platelet count showed the highest hazard ratio in patients with hemato logic malignancy. In patients with liver disease, the hazard ratio for antithrombin levels was significantly high. CONCLUSIONS Decreased plasma anticoagulant levels reflect florid consumption of the physiologic defense system against DIC-induced hypercoagulation. Plasma antithrombin and protein C levels are powerful prognostic markers of DIC, especially in patients with sepsis/severe infection.

Abstract
INTRODUCTION To test the hypothesis that the administration of antithrombin concentrate improves disseminated intravascular coagulation (DIC), resulting in recovery from DIC and better outcomes in patients with sepsis, we conducted a prospective, randomized controlled multicenter trial at 13 critical care centers in tertiary care hospitals. METHODS We enrolled 60 DIC patients with sepsis and antithrombin levels of 50 to 80% in this study. The participating patients were randomly assigned to an antithrombin arm receiving antithrombin at a dose of 30 IU/kg per day for three days or a control arm treated with no intervention. The primary efficacy end point was recovery from DIC on day 3. The analysis was conducted with an intention-to-treat approach. DIC was diagnosed according to the Japanese Association for Acute Medicine (JAAM) scoring system. The systemic inflammatory response syndrome (SIRS) score, platelet count and global markers of coagulation and fibrinolysis were measured on day 0 and day 3. RESULTS Antithrombin treatment resulted in significantly decreased DIC scores and better recovery rates from DIC compared with those observed in the control group on day 3. The incidence of minor bleeding complications did not increase, and no major bleeding related to antithrombin treatment was observed. The platelet count significantly increased; however, antithrombin did not influence the sequential organ failure assessment (SOFA) score or markers of coagulation and fibrinolysis on day 3. CONCLUSIONS Moderate doses of antithrombin improve DIC scores, thereby increasing the recovery rate from DIC without any risk of bleeding in DIC patients with sepsis.
