Insights

Supplemental antithrombin (AT) may reduce mortality in sepsis-induced disseminated intravascular coagulation (DIC). This study found a potential benefit, but further research is needed to confirm the effectiveness of AT for DIC patients.

Area of Science:

  • Critical Care Medicine
  • Hematology
  • Pharmacology

Background:

  • Sepsis-induced disseminated intravascular coagulation (DIC) is a life-threatening condition.
  • Supplemental antithrombin (AT) is used in Japan for DIC, but evidence is limited.
  • The benefits of AT supplementation for sepsis-induced DIC require further investigation.

Purpose of the Study:

  • To evaluate the effect of AT supplementation on in-hospital mortality in patients with sepsis-induced DIC.
  • To clarify the association between AT use and clinical outcomes in severe sepsis with DIC.
  • To assess the safety profile, including bleeding complications, of AT supplementation.

Main Methods:

  • Multicenter retrospective observational study of 3,195 severe sepsis patients.
  • Analysis of 1,784 patients diagnosed with DIC, comparing AT group (n=715) and control group (n=1,069).
  • Propensity score analyses, including inverse probability of treatment weighting, quintile stratification, and matching, were employed.

Main Results:

  • Inverse probability of treatment-weighted analysis showed a significant association between AT supplementation and lower in-hospital mortality (OR: 0.748, P=0.034).
  • Quintile-stratified and propensity score matching analyses did not confirm this association (P=0.117 and P=0.263, respectively).
  • Early survival rates were higher in the propensity score-matched AT group; severe bleeding complications did not increase despite higher transfusion needs.

Conclusions:

  • Antithrombin supplementation may be associated with reduced in-hospital mortality in sepsis-induced DIC patients.
  • The statistical robustness of this association was not strong, indicating a need for further validation.
  • AT supplementation did not increase severe bleeding complications, but transfusion requirements were higher.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
