Reversal of Dabigatran Bleeding and Coagulopathy Using Idarucizumab in a Patient With Acute Kidney Injury.

Idarucizumab is approved for patients treated with dabigatran when reversal of the anticoagulant effects is needed. Like dabigatran, idarucizumab is excreted in the urine. The effect of renal dysfunction on drug elimination is uncertain, as patients in the RE-VERSE AD trial had a median creatinine clearance of 58 mL/min. Also, dabigatran accumulation can occur if the international normalized ratio (INR) is greater than two. A 73-year-old female was admitted for lower extremity edema and increased abdominal girth. On admission, the patient was in acute kidney injury (AKI) with an estimated creatinine clearance of 34.5 mL/min. Her prothrombin time (PT) on admission was 17 seconds, her INR was 1.4, and her hemoglobin was 8.7 gm/dL (12-16 gm/dL). Throughout her admission, she was continued on her home regimen of dabigatran 150 mg twice daily for atrial fibrillation. On day 4, she had rectal bleeding and altered mental status. At this time, her PT was elevated to 25.6 seconds, her INR had increased to 2.3, and her hemoglobin had dropped to 6.8 gm/dL. Two doses of idarucizumab 2.5 gm were administered, and dabigatran was successfully reversed with cessation of bleeding and normalization of the INR to 1.5. An additional dose of idarucizumab was not required. The patient was discharged home two days later. Idarucizumab successfully reversed the bleeding and coagulopathy associated with dabigatran in a patient with AKI.

Gastric Lipomas: A Case Series and Review of the Literature.

Introduction: The purpose of this case series was to review a rare subset of tumors known as gastric lipomas, which are typically found incidentally. The motivation for this study arose from the identification of 2 cases within our institution in a short period. Case Presentation: The study involved a review of the diagnosis and management of 2 patients presenting with gastric lipomas at our institution after symptoms of gastrointestinal bleeding. With the advent of new radiologic investigations such as computed tomography and magnetic resonance imaging and advances in endoscopy, there are new approaches to identifying and managing these tumors. On further evaluation of the literature, we found that despite the availability of minimally invasive endoscopic techniques such as mucosal resection and submucosal dissection in the setting of large tumors, most patients tend to have to resort to surgical management. Conclusion: This case series underscores the rarity of gastric lipomas and their often-incidental discovery. Further investigation into endoscopic approaches for managing these tumors is needed, and additionally, there is a need to explore a potential association between gastric lipomas and malignancy, as chronic inflammation of the overlying mucosa may play a significant role.
