AbstractThe objective was to estimate the effect of antithrombin therapy on mortality in disseminated intravascular coagulation (DIC) of severe sepsis and septic shock. Randomized clinical trials (RCT) on patients with DIC and severe sepsis or septic shock assigned to intravenous antithrombin or placebo were searched. Eligible studies reported death as the outcome measure. Of 35 RCT, 32 trials were excluded because patients were not randomized to antithrombin versus placebo, or no separate data on patients with DIC were given. In three RCT, 364 patients with severe sepsis or septic shock and DIC were randomized. The disease severity, definition of DIC, dose and duration of treatment varied among the trials. In two of the three RCT, data were from subgroup analyses (patients not stratified by DIC). The combined odds ratio for short-term all-cause mortality in those who received antithrombin was 0.649 (95% confidence interval, 0.422-0.998). Data on bleeding complications in patients treated with antithrombin were reported only in one of the RCT and were not considered suitable for systematic safety estimation. In sepsis patients with DIC, administration of antithrombin concentrate may increase overall survival. Current available evidence, however, is not suited to sufficiently inform clinical practice.
