Adjunct Immune Globulin for Vaccine-Induced Immune Thrombotic Thrombocytopenia.

The use of high-dose intravenous immune globulin (IVIG) plus anticoagulation is recommended for the treatment of vaccine-induced immune thrombotic thrombocytopenia (VITT), a rare side effect of adenoviral vector vaccines against coronavirus disease 2019 (Covid-19). We describe the response to IVIG therapy in three of the first patients in whom VITT was identified in Canada after the receipt of the ChAdOx1 nCoV-19 vaccine. The patients were between the ages of 63 and 72 years; one was female.

Management of bleeding complications in patients with cancer on DOACs.

There has been a concern that major bleeding events (MBE) on direct-acting oral anticoagulants (DOACs) will be more difficult to manage than on vitamin K antagonists. Patients with cancer and DOAC-associated bleeding may be even more of a challenge to manage. We therefore reviewed the literature on bleeding in patients with cancer on DOACs.
