Background Although antibody-mediated rejection (AMR) is described in other solid organ transplant populations, the literature describing the management following lung transplantation is limited. Objective The purpose of this study is to evaluate the management strategies of AMR in lung transplant recipients. Methods This single-center, retrospective study described the management of AMR in adult lung transplant recipients who received treatment with rabbit antithymocyte globulin, bortezomib, rituximab, intravenous immune globulin (IVIG), and/or plasmapheresis between September 2015 and June 2019. Results A total of 270 medication orders for 55 patient admissions were included in the primary outcome analysis. The most commonly used regimen consisted of IVIG, plasmapheresis, and rituximab (49.1%; n = 27), followed by IVIG and plasmapheresis alone (27.3%, n = 15). A total of 51 patients (93%) received plasmapheresis as part of their AMR treatment, with a median of 4 [3, 5] sessions per encounter; 86% of patients with positive donor-specific antibodies (DSAs) had a reduction in DSAs following AMR treatment. Overall, 23.5% of patients had noted allograft failure or need for retransplantation. A total of 10 patients died during the AMR treatment hospital admission, and an additional 11 patients died within 1 year of the initial encounter. Conclusion and Relevance This represents the largest report describing management strategies of AMR in lung transplant recipients. Although practice varied, the most commonly used regimen consisted of plasmapheresis, IVIG, and rituximab.

Background: Vaccine preventable diseases can affect solid organ transplant recipients post-transplant. Therefore, the administration of vaccines and assessment of serologic response should be prioritized in the pre-transplant period.Methods: This single-center, retrospective study included 349 adult heart or lung transplant candidates between December 1, 2017 and November 30, 2019. We describe vaccination or serologic status for hepatitis A, hepatitis B, tetanus, pneumococcal, influenza, and other recommended vaccinations among heart or lung transplant candidates.Results: Eighty-two heart transplant candidates (91%) and 77 lung transplant candidates (30%) received an ID consult prior to transplant. More patients completed the pneumococcal series (66.7% vs. 28.6%, P = .045) in the heart transplant group that received an ID consult. In the lung transplant group, patients with an ID consult demonstrated higher rates of immunity to hepatitis A (84.4% vs. 72.9%, P = .047), hepatitis B (75.3% vs. 56.9%, P = .005), and measles (71.4% vs. 52.5%, P = .005) compared to those without. Conclusions:Our results demonstrate the value of consulting ID and administering vaccinations in the early evaluation phase, prior to transplant listing. Opportunities remain to better optimize vaccination rates prior to transplant in heart and lung transplant candidates.
