ABSTRACT
During the COVID pandemic, the British Thoracic Society recommended first-line indwelling pleural catheter (IPC)insertion or therapeutic aspiration for malignant pleural effusion (MPE) instead of admission for chest drain and talcpleurodesis to minimise hospital visits. This study aimed to review the uptake and usage of IPCs during and followingthe pandemic and its potential cost-effectiveness.Retrospective data analysis of IPCs between 2020-2021 was performed. Data collection included patient sex, age,WHO performance status (PS), indication and duration of IPC.187 IPCs were inserted;91% for MPE. 75% elected for IPC as first-line. 57% patients were PS 0-1 and 77% werePS 0-2. In 2020, 30% patients were self-draining compared to 12% in 2021. Mean duration IPC in-situ was 87 days(median 68 days). The pandemic saw increased use of first-line IPCs (75% 2020 vs 52% 2019) particularly in patients with good PS. This reduced initial hospitalisation (4.08 bed days) with an estimated cost saving of 1200 (300/day) per patient. Self-drainage rates also increased from 13% (2019) to 30% (2020) but have returned to pre-pandemic levels of selfdrainage at 12% in 2021 with need for district nurse visits for up to 3 months. Current practice of widespread first-line IPC use in the COVID endemic era may not be cost-effective and needs to be reviewed alongside the pre-existing evidence base.

SESSION TITLE: Problems in the Pleura Case Posters 1 SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Ibrutinib is an irreversible inhibitor of Bruton's tyrosine kinase (Btk), approved for treatment of a variety of B-cell malignancies, including chronic lymphocytic leukemia (CLL). There is an association of increased risk of bleeding with ibrutinib due to platelet dysfunction caused by the medication. Bleeding is usually non-life threating such as subcutaneous or mucosal bleeding, epistaxis, and ecchymosis. But major bleeding has been reported such as intracranial hemorrhage and gastrointestinal hemorrhage. Thoracic complications from ibrutinib are rare. Below is a case report discussing a hemorrhagic pleural effusion thought to be caused by Ibrutinib. CASE PRESENTATION: Patient is a 78-year-old male initially diagnosed with CLL on flow cytometry showing a low-grade B cell lymphoproliferative process. Patient was monitored by Hematology and when kappa light chain numbers began to rise, a bone marrow biopsy was performed showing 90% infiltration of the marrow with lymphoid cells. Patient was started on Ibrutinib therapy and responded well to treatment. A year after starting therapy, patient presented to the emergency room with increased shortness of breath and fatigue. Patient was found to be COVID-19 positive and chest x-ray showed a large right sided pleural effusion. Thoracentesis was performed draining 1650cc of bloody fluid. Fluid studies revealed a lymphocytic effusion with RBC count 1,185375, WBC of 1751. Cultures and cytology were negative. On further history, patient was without recent trauma or surgery, CTA chest was negative for pulmonary embolism. QuantiFERON Gold test was negative, indicating low likelihood of tuberculosis. Patient was not on any antiplatelet or systemic anticoagulation medications. Ibrutinib therapy was held during hospitalization and pleural effusion did not reaccumulate. Patient passed away during hospital stay secondary to respiratory failure due to COVID-19. DISCUSSION: Ibrutinib is an orally bioavailable bruton tyrosine kinase inhibitor (BTKi) and forms an irreversible covalent bound to BTK at the Cysteine-481 residue. Ibrutinib predisposes to bleeding by inhibiting BTK and Tec, which play a role in the inhibitory signaling pathway of platelet collagen receptors such as glycoprotein VI (GP VI) and C-type lectin-like receptor 2 (CLEC-2). Our patient had no other risk factors for developing a hemorrhagic effusion. CLL itself can cause malignant effusions, one study found the incidence of malignant effusions among patients with CLL to be 9%, but the effusion was noted to be serous or serosanguinous and there was pleural involvement in all patients which was not the case in our patient. CONCLUSIONS: There is currently a minimal amount of data to guide clinicians regarding the use of ibrutinib in patients at high risk of bleeding or on anticoagulant or antiplatelet therapy. It is important to realize bleeding complications related to ibrutinib therapy can occur. Reference #1: Shatzel JJ, Olson SR, Tao DL, McCarty OJT, Danilov AV, DeLoughery TG.

ABSTRACT
SESSION TITLE: Problems in the Pleura Case Posters 2 SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Hematologic malignancies can often be complicated by pleural effusion due to leukemic infiltration of the pleura (1). Long term management of resulting chronic plural effusion can be complicated when there is evidence of trapped lung. Subsequent infection may lead to development of chronic empyema which can be difficult to manage in chronically ill patients (2). CASE PRESENTATION: A 65-year-old male with history of chronic myeloid leukemia status post stem cell transplant was admitted with dyspnea and cough. Computed tomography (CT) chest imaging revealed increased volume loss on the left with new air fluid level in a chronic left pleural effusion. (Image 1) Patient's history was significant for chronic left pleural effusion, which was first identified in 2015 and found to be a malignant effusion with evidence of leukemia involvement. Repeat imaging in 2018 (Image 2) revealed continued chronic pleural effusion. Patient was admitted in August 2021 with COVID-19 pneumonia and CT Chest showed chronic loculated left sided pleural effusion. Patient elected to continue to monitor the chronic effusion, which was completed as outpatient every 4 to 6 weeks (Image 3). He remained clinically stable until the presentation to a hospital in January 2022. The chronic empyema was initially managed with tube thoracostomy, intrapleural fibrinolytics and antibiotics. Cultures were significant for Moraxella catarrhalis and Streptococcus pneumoniae. He was determined to be a poor surgical candidate for decortication and treatment with empyema tube was initiated. The empyema tube was incrementally withdrawn as an outpatient and subsequently removed with good clinical recovery. DISCUSSION: Chronic empyema is characterized by thickened parietal and visceral pleura which limits the ability of the lung to re-expand. Surgical management with decortication is the definitive management, however, in poor surgical candidates, management becomes more complicated. Open pleural drainage with an open pleural window can be considered. An alternative option converts tube thoracostomy to open pleural drainage, as was utilized in this patient (2). While comparison of surgical vs non-surgical management of empyema suggests similar mortality (3), non-surgical management of chronic empyema needs more investigation to determine the optimal treatment modality. CONCLUSIONS: Empyema remains a difficult condition to manage. Treatment modalities of chronic empyema are limited in those patients who remain poor surgical candidates.
