Dear Sir, In a previous study published in the Journal, we reported the efficacy and safety of 4-factor prothrombin complex concentrate (4F-PCC) in achieving clinical hemostasis in 29 patients receiving the direct oral anticoagulants (DOACs) apixaban or rivaroxaban presenting with major bleeding necessitating the use of a reversal agent [1]. We hereby report the results of 12 additional patients who received the same hemostatic agent for the same indication from July 1, 2018 to June 30, 2019. The 12 studied patients’ mean ± SD age was 78.8 ± 14.5 years and seven (58.3%) of them were females. The most common indication for apixaban and rivaroxaban use was atrial fibrillation (AF) (n = 9, 75%), followed by deep venous thrombosis (DVT)/pulmonary embolism (PE) (n = 2, 16.7%), and peripheral arterial disease (n = 1, 8.3%). The most common site of bleeding was intracerebral hemorrhage (ICH) (n = 10, 83.3%) followed by gastrointestinal (GI) bleed (n = 1, 8.3%) and musculoskeletal bleed (n = 1, 8.3%). All patients received the last DOAC dose on the same day of hospital admission and had normal platelet counts and liver enzyme levels. Patients received a single time dose the 4F-PCC Kcentra at a dose of 50 units/kg intravenously based on actual body weight (maximum of 5000 units). Clinical hemostasis, assessed according to International Society of Thrombosis and Hemostasis (ISTH) Scientific and Standardization Subcommittee criteria, was achieved in eight (66.7%) patients. Patients who did not achieve clinical hemostasis (4, 33.3%) suffered from ICH and three of them died during * Marwan Sheikh‑Taha [email protected] 1

hospitalization except one who was discharged with neurologic deterioration. Table 1 describes bleeding management outcomes. In addition to the 4F-PCC, three patients received packed red blood cells and one patient with GI bleed received a proton pump inhibitor to control bleeding. In our study, the achievement of clinical hemostasis, 66.7%, was comparable to 65% as reported by Schulman et al. [2], 69.1% as reported by Majeed et al. [3], and 72.4% as reported in our previous study [1]. On the other hand, hemostasis was achieved in 80.6% of patients as reported by Smith et al. [4]. Four patients (33.3%) failed to achieve hemostasis and all of them suffered from ICH (three died during hospitalization and one suffered from neurologic deterioration upon hospital discharge). One patient (8.3%), a 78-year-old male suffering from ICH developed right leg DVT on day 8 after receiving 4F-PCC. He was on apixaban 5 mg twice daily for DVT/ PE treatment. The occurrence of thromboembolism in our study is comparable
