title: Is antithrombin treatment of disseminated intravascular coagulation a quixotic goal?
abstract: The development of disseminated intravascular coagulation (DIC) is associated with increased sepsis mortality. Antithrombin (AT) is one of several anticoagulants that have been studied in randomized trials of sepsis without benefit. In a recent study, Iba and colleagues reviewed data from patients who were treated for sepsis-related DIC with two lower doses of AT concentrate than studied in prior trials. Patients received 1,500 IU/day (n = 259) or 3,000 IU/day (n = 48) of AT for 3 days. All patients had baseline antithrombin activity <40% and there was no placebo group. The AT 3,000 group had higher 28-day survival as well as a higher rate of DIC resolution than the AT 1,500 group. Though intriguing, the study findings are limited by the non-randomized retrospective nature of the findings, which resulted in baseline differences in multiple confounders that affect mortality, as well as the lack of a placebo group to compare outcomes.
