Managing Subdural Bleeding Associated With Rivaroxaban: A Series of 3 Cases

The impact of prothrombin complex concentrates when treating DOAC-associated bleeding: a review

Background

Bleeding complications are a risk associated with all anticoagulants. Currently, the treatment options for the management of direct oral anticoagulant (DOAC)-associated bleeding are limited. Prothrombin complex concentrates (PCCs) have been proposed as a potential therapeutic option, and evidence regarding their use is increasing.

Review

Many studies supporting PCC have used preclinical models and healthy volunteers; however, more recently, observational studies have further improved insight into current DOAC reversal strategies. Multiple clinical practice guidelines now specifically suggest use of PCCs for this indication. Specific reversal agents for Factor Xa inhibitors may become available in the near future, but data on their efficacy are still emerging.

Conclusions

Ultimately, a multimodal approach may be the optimal strategy to restore haemostasis in patients presenting with DOAC-associated coagulopathy.

The Use of 3- and 4-Factor Prothrombin Complex Concentrate in Patients With Elevated INR

BACKGROUND

PCC (Kcentra®) is an Food and Drug Administration (FDA)-approved 4-factor PCC used for the treatment of warfarin-related coagulopathy (WRC), but it has also been used off-label to treat non-WRC. Three-factor PCC in the form of coagulation factor IX human (Bebulin®) has also been used for WRC and off-label to treat non-WRC. It is unclear whether the use of 3- or 4-factor PCCs is effective for the treatment of non-WRC,.

OBJECTIVE

Our aim is to characterize the use of 3- and 4-factor PCCs for patients identified with a non-WRC.

METHODS

A retrospective analysis of patients who received PCCs for both WRC and non-WRC between January 2012 and July 2015 was conducted.

RESULTS

A total of 187 patients with elevated international normalized ratio (INR) who received PCCs were analyzed; 53.9% of patients in the WRC group and 27.7% in the non-WRC group corrected to an INR of 1.3 or less after 3- or 4-factor PCC administration. In those patients with non-WRC and who had underlying liver disease, 3- and 4-factor PCCs reduced mean INR by 0.98 and 1.43, respectively.

CONCLUSION

Three and 4-factor PCCs can reduce INR in patients with WRC and in those with non-WRC secondary to liver disease.
