A randomized, controlled, multicenter trial of the effects of antithrombin on disseminated intravascular coagulation in patients with sepsis.

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.

Project description:BackgroundDisseminated intravascular coagulation (DIC) syndrome is a highly lethal condition characterized by the complication of multiple organ damage. Although the effects of combined antithrombin (AT) and recombinant thrombomodulin (rTM) on DIC syndrome have previously been examined, the results are inconsistent and inconclusive. Therefore, we conducted a systematic review on the combined administration of AT and rTM for the treatment of septic DIC to investigate the superiority of the combination therapy over either AT or rTM monotherapy using a random-effects analysis model.MethodWe searched electronic databases, including Medline, Cochrane Central Register of Controlled Trials, Scopus, and Igaku-Chuo Zasshi (ICHU-SHI) Japanese Central Review of Medicine Web from inception to January 2022. Studies assessing the efficacy of combined AT and rTM were included. The primary outcome was all-cause mortality, and the secondary outcome was occurrence of serious bleeding complications compared to monotherapy. We presented the pooled odds ratio (OR) or hazard ratio (HR) with 95% confidence intervals (CI) depending on reporting results in each primary study.ResultsWe analyzed seven enrolled clinical trials, all of which were observational studies. Combination therapy had a non-significant favorable association with lower 28-day mortality compared to monotherapy (HR 0.67 [0.43-1.05], OR 0.73 [0.45-1.18]). The I2 values were 60% and 72%, respectively, suggesting high heterogeneity. As a secondary outcome, bleeding complications were similar between the two groups (pooled OR 1.11 [0.55-2.23], I2 value 55%).ConclusionsAlthough the findings in this analysis could not confirm a statistically significant effect of AT and rTM combination therapy for septic DIC, it showed a promising effect in terms of improving mortality. The incidence of bleeding was low and clinically feasible. Further research is warranted to draw more conclusive results.Trial registrationThis study was registered in the University Hospital Medical Information Network (UMIN) Clinical Trials Registry (UMIN ID: 000049820).

Project description:Background:A recombinant form of antithrombin (AT), called AT gamma, is being developed as an alternative to AT derived from human plasma. To compare the efficacy and safety of AT gamma to plasma-derived AT (pAT), we conducted a randomized, open-label, multicenter trial in patients with sepsis-induced disseminated intravascular coagulation (DIC). Methods:Eligible patients, recruited at 30 clinical sites, had been diagnosed with sepsis-induced DIC (by the Japanese Association for Acute Medicine [JAAM] DIC criteria) and AT activity at 70% or below. Patients were randomized 1:1 to either 36 IU/kg/day AT gamma (n?=?110) or 30 IU/kg/day pAT (n?=?112), both administered intravenously for 5 days. The primary endpoint was recovery from DIC at day 6 or early study withdrawal. DIC recovery was defined as a DIC score of less than four. Secondary endpoints were DIC score, outcome on day 28, sequential organ failure assessment score, acute physiology and chronic health evaluation II score (APACHE II), and plasma AT activity. Adverse events and adverse drug reactions were recorded using MedDRA/J version 16.0. Results:Baseline patient demographics and clinical features were similar in the two treatment groups. On day 6 (or at withdrawal), DIC recovery had occurred in 62 of 110 (56.4%; 95% confidence interval, 46.6-65.8%) patients in the AT gamma group and 59 of 112 (52.7%; 95% confidence interval, 43.0-62.2%) patients in the pAT group. In both treatment groups, DIC recovery rate values tended to be higher when stratified by baseline AT activity rates. All changes in other secondary endpoints were similar in both treatment groups. Safety was also similar in the two treatment groups. Adverse events occurred in 89 of 108 (82.4%) patients in the AT gamma group and 99 of 113 (87.6%) patients in the pAT group. Conclusions:Safety and efficacy were similar for 36 IU/kg/day AT gamma and 30 IU/kg/day pAT. These results confirm that AT gamma is an excellent alternative to pAT for improving outcomes for patients with DIC. Trial registration:ClinicalTrials.gov identifier: NCT01384903; June 2011.
