Does idarucizumab followed by recombinant tissue plasminogen activator improve symptoms in a patient with ischemic stroke on dabigatran?
Idarucizumab successfully reverses dabigatran anticoagulation, enabling the safe and effective use of rtPA thrombolysis in acute ischemic stroke.
BACKGROUND: Effective anticoagulation routinely precludes patients from receiving intravenous thrombolysis with recombinant tissue plasminogen activator to reverse severe symptoms of ischemic stroke. We report what we believe to be the first case of ischemic stroke successfully treated with recombinant tissue plasminogen activator after antagonizing dabigatran with the monoclonal antibody idarucizumab, recently approved worldwide. CASE PRESENTATION: A 75-year-old Caucasian man presented to our hospital with severe aphasia and mild hemiparesis. After providing written consent, he received two doses of 2.5 g of idarucizumab over 20 minutes followed by standard protocol in-label recombinant tissue plasminogen activator application. All symptoms resolved within 1 h. CONCLUSIONS: Applying a recombinant tissue plasminogen activator after antagonizing dabigatran with idarucizumab is feasible and easy to manage in an emergency room or stroke unit. Thus, idarucizumab represents a new therapeutic option for patients receiving dabigatran treatment, reestablishing their eligibility for recombinant tissue plasminogen activator thrombolysis.
