    Abstract The presence of a certain group of auto-antibodies (AAbs) is known to correlate with the severity of COVID-19. It is, however, unknown if such AAbs are prevalent and impact COVID-19-related outcomes in lung transplant recipients (LTRs) who are immunosuppressed. We performed a retrospective study of LTRs with COVID-19 and analyzed samples before and after COVID-19 for IgG AAbs. AAbs analysis was carried out using autoimmune and coronavirus microarray and the resulting cross-sectional differences in Ab-scores and clinical variables were analyzed using Fischer's Exact test for categorical variables and a paired

    Abstract Background: There is lack of data reporting outcomes among patients needing diaphragmatic plication (DP) during or after lung transplantation (LT). We sought to assess the association of DP with post-transplant spirometry among other outcomes.
    Methods: We included all patients who underwent LT between 2012 and 2016 (n = 324, mean age 56.3±13.4 years; M:F 198:126). We compared early and late outcomes based on the need for DP.
    Results: The frequency of diaphragmatic dysfunction (DD) on pre-transplant fluoroscopy was 52.2%. A total of 38 DP procedures were performed among 37 patients (11.4% of LT patients). DP was done for anatomic (sizing or spacing issues) or functional indications (symptomatic DD). While patients with DP had significantly lower spirometry throughout the 3-year follow-up period, their slope of decline, functional assessments at the first annual visit, the risk of CLAD, and mortality were similar to patients without DP. A sub-group analysis limited to patients with restrictive lung diseases as the transplant indication had similar findings.
    Conclusions: Pre-transplant DD is common among LT candidates although it did not predict the need for DP. DP may be performed for functional or anatomic indications especially for addressing the donor-recipient size mismatch. Despite the lack of favorable effect on post-transplant spirometry, patients undergoing DP have acceptable and comparable early and late outcomes.

    Abstract A lung transplant (LT) patient developed 2 distinct episodes of COVID-19, confirmed by whole-genome sequencing, which was caused by the Delta, and then followed 6 weeks later, by the Omicron variant. The clinical course with Omicron was more severe, leading us to speculate that Omicron may not be any milder among LT patients. We discuss the potential mechanisms behind the Omicron not being any milder among LT patients and emphasize the need for outcomes data among these patients. Until such data become available, it may be prudent to maintain clinical equipoise as regards the relative virulence of the newer variants among LT patients.

    Abstract Background: Despite multiple studies evaluating the immunological responsiveness to vaccines, the clinical effectiveness of the two-dose mRNA vaccine schedule among lung transplant (LT) patients has not been evaluated.
    Methods: We included LT patients who tested positive for SARS-CoV-2 on a nasopharyngeal swab between March 1, 2020, and August 25, 2021 (n = 70). The study group was divided based on their vaccination status.
    Results: During the study period, 14 fully vaccinated LT patients with one of the mRNA vaccines tested positive for COVID-19 (median age 54, range 30-62 years, M:F 9:5). The vaccinated cohort was younger with bilateral LT, have suppurative conditions as the transplant indication, and present with milder symptoms. However, pulmonary parenchymal involvement was seen among all 12 patients where computed tomography (CT) of chest was available. The laboratory profile indicated a more subdued inflammatory response among the vaccinated group. A lower proportion of vaccinated patients developed respiratory failure, needed ICU admission or ventilator support, although none of the differences achieved statistical significance. None of the vaccinated patients succumbed to COVID-19 during the study period, while the 4-week mortality among unvaccinated patients was nearly 15% (8/56).
    Conclusions: In this cohort of vaccinated LT patients who developed breakthrough COVID-19, the clinical course, risk of complications, and outcomes trended better than unvaccinated patients. However, universal involvement of the allograft demonstrates the continued vulnerability of these patients to significant sequelae from COVID-19. Future studies may evaluate the incremental protection of vaccination after the completion of the third dose of mRNA vaccines among LT patients.

    Abstract Background: Studies indicate that the recovery from coronavirus disease 2019 (COVID-19)-associated acute respiratory distress syndrome may be slower than other viral pneumonia. There are limited data to guide decisions among patients who need extracorporeal membrane oxygenation (ECMO) support, especially the expected time of recovery and considering lung transplantation (LT).
    Methods: This was a retrospective chart review of patients with COVID-19-associated acute respiratory distress syndrome placed on ECMO between March 1, 2020, and September 15, 2021 (n = 20; median age, 44 y; range, 22-62 y; male:female, 15:5). We contrasted the baseline variables and clinical course of patients with and without the need for ECMO support >30 d (ECMO long haulers, n = 10).
    Results: Ten patients met the criteria for ECMO long haulers (median duration of ECMO, 86 d; range, 42-201 d). The long haulers were healthier at baseline with fewer comorbidities but had worse pulmonary compliance and higher partial pressure of CO2. They had a significantly higher number of membrane oxygenator failures, changes to their cannulation sites, and suffer more complications on ECMO. One of the long hauler was bridged to LT while another 6 patients recovered and were discharged. Overall survival was better among the ECMO long haulers (70% versus 20%; 9.3, 1.2-73; P = 0.03).
    Conclusions: Despite worse pulmonary physiology, frequent complications, and a tortuous hospital course that may appear to portend a poor prognosis, ECMO long haulers have the potential to recover and be weaned off ECMO without the need for LT. A customized approach comprising a more conservative timeline for the consideration of LT may be prudent among these patients.

    Abstract Background: There are limited data on management strategies and outcomes among lung transplant (LT) patients with Coronavirus disease 2019 (COVID-19). We implemented management protocols based on the best available evidence and consensus among multidisciplinary teams. The current study reports our experience and outcomes using this protocol-based management strategy.
    Methods: We included single or bilateral LT patients who tested positive for SARS-CoV-2 on nasopharyngeal swab between March 1, 2020, to December 15, 2020 (n = 25; median age: 60, range 20-73 years; M: F 17:8). A group of patients with Respiratory Syncytial Virus (RSV) infection during 2016-18 were included to serve as a comparator group (n = 36).
    Results: As compared to RSV, patients with COVID-19 were more likely to present with constitutional symptoms, spirometric decline, pulmonary opacities, new or worsening respiratory failure, and need for ventilator support. Patients with SARS-CoV-2 infection were less likely to receive a multimodality treatment strategy, and they experienced worse post-infection lung function loss, functional decline, and three-month survival. A significant proportion of patients with COVID-19 needed readmission for worsening allograft function (36.4%), and chronic kidney disease at initial presentation was associated with this complication. Lower pre-morbid FEV
    Conclusions: Despite similar demographic characteristics and predispositions, LT patients with COVID-19 are sicker and experience worse outcomes as compared to RSV. Despite the availability of newer therapeutic agents, COVID-19 continues to be associated with significant morbidity and mortality.

    Abstract Background: There is limited data on the predictors and outcomes of new or worsening respiratory failure among lung transplant (LT) patients with Coronavirus disease 2019 (COVID-19).
    Methods: We included all the LT patients diagnosed with COVID-19 during a 1-year period (March 2020 to February 2021; n = 54; median age: 60, 20-73 years; M:F 37:17). Development of new or worsening respiratory failure (ARF) was the primary outcome variable.
    Results: The overall incidence of ARF was 48.1% (n = 26). More than 20% of patients (n = 11) needed intubation and mechanical ventilation. Body mass index > 25 Kg/m
    Conclusions: COVID-19 is associated with significant morbidity and mortality among LT patients. Patients on chronic anticoagulation seem to enjoy favorable outcomes, while higher BMI and peak D-dimer levels are associated with development of ARF. Pre-infection CLAD is associated with an increased risk of death from COVID-19.

    Abstract Background: There are limited data regarding the clinical efficacy of COVID-19 vaccines among lung transplant (LT) patients.
    Methods: We included all LT patients diagnosed with COVID-19 between March 1, 2020, and December 10, 2021 (n = 84; median age 55, range, 20-73 years; males 65.5%). The study group was divided into 3 groups based on the vaccination status (patients who did not complete the primary series for any of the vaccines: n = 58; those with 2 doses of messenger RNA (mRNA) or 1 dose of the adenoviral vector vaccine, vaccinated group: n = 16; those with at least 1 additional dose beyond the primary series, boosted group: n = 10).
    Results: Pulmonary parenchymal involvement on chest computed tomography scan was less common among the boosted group (P = .009). The proportion of patients with new or worsening respiratory failure was significantly lower among the vaccinated and boosted groups and these patients were significantly more likely to achieve the composite endpoint of oxygen-dependence free survival (P = .02). On multivariate logistic regression analysis, higher body mass index, restrictive lung disease as the transplant indication, and preinfection chronic lung allograft dysfunction were independently associated with acute or acute on chronic respiratory failure while being on therapeutic dose anticoagulation and having received the booster dose had a protective effect.
    Conclusion: COVID-19 vaccines appear to have several favorable effects among LT patients with breakthrough infections including lower likelihood of allograft involvement on imaging (among boosted patients), need of hospitalization, and complications such as new or worsening respiratory failure.
