Summary: This study examined the performance of models predicting waitlist and posttransplant survival in lung transplant allocation. The results showed that different models had similar performance in predicting waitlist and posttransplant survival, and using alternative modeling strategies and contemporary cohorts did not improve the models' performance in determining access to lung transplant.

Summary: Chronic lung allograft dysfunction (CLAD), characterized by decline in pulmonary function and bronchiolitis obliterans, lacks approved therapies. Single-cell RNA-Seq and spatial transcriptomic analysis identified the important role of JAK-STAT signaling in airway epithelial cells in CLAD. Activation of JAK-STAT signaling leads to upregulation of MHC-I in airway basal cells, resulting in cytotoxic T cell-mediated basal cell death. This study provides mechanistic insight and potential therapeutic strategy for CLAD.

Summary: The social distancing measures during COVID-19 led to a reduction in respiratory virus infection rates, which correlated with less decline in lung function, fewer episodes of TDLF, and possibly lower incidence of CLAD in lung transplant recipients.

Summary: In this study, a machine learning computed tomography (CT) lung texture analysis tool was used for phenotyping and prognostication of chronic lung allograft dysfunction (CLAD) in lung transplant recipients. The results showed that machine learning could effectively distinguish different CLAD phenotypes, and the associated parameters were able to predict the risk of graft failure.

Summary: This study adapted the 2019 International Society for Heart and Lung Transplantation criteria to define novel phenotypes of pulmonary chronic graft-versus-host disease (PcGVHD) and compared its performance with the NIH criteria in identifying high-risk PcGVHD patients. The adapted criteria were found to be effective in identifying high-risk PcGVHD patients that were missed by the NIH criteria.

Summary: Bronchiolitis obliterans syndrome is the most common form of CLAD, and its pathogenesis and markers play a crucial role in early diagnosis and treatment.

Summary: This study aims to determine the prognostic significance of D-LCOcor on chronic lung allograft dysfunction (CLAD) and survival. The results show that low baseline D-LCOcor is significantly associated with death, and declines in D-LCOcor are associated with shorter survival. This suggests that D-LCOcor may be a useful marker for predicting poor outcomes after lung transplantation.

Summary: This study found that pleural thickening identified by lung ultrasound may serve as a potential surrogate marker to distinguish restrictive allograft syndrome (RAS) from bronchiolitis obliterans syndrome (BOS) in chronic lung allograft dysfunction (CLAD) patients after lung transplant. This discovery provides a new method for clinical diagnosis of CLAD patients post lung transplant.

Summary: This study examined the viable bacterial community in bronchoalveolar lavage samples from 64 lung transplant recipients and identified four distinct compositional states, called "pneumotypes," which were associated with immune activity, lung function, and risks of infection and rejection. The findings highlight the link between the lung microbial ecosystem, human lung function, and clinical stability post-transplant.

Summary: The poor outcomes of the two specific CLAD phenotypes suggest the urgent need for future therapeutic randomized trials. The high number of missing values in a potential trial is most frequently attributed to death. Survival may be used as an endpoint in clinical trials in these distinct phenotypes, and imputation techniques are relevant if graft function is used as a surrogate of disease progression in future trials.

Summary: This study compares the impact of pretransplant red blood cell transfusion on patient survival and post-transplant adverse events, finding that transfused patients have higher incidence of adverse events and increased mortality risk, but no significant association with chronic graft rejection development.

Summary: miR-21 expression was higher in restrictive allograft syndrome (RAS) than in bronchiolitis obliterans syndrome (BOS) specimens, with a significant increase in serum concentration over time in RAS patients. Vimentin, NICD, and p-SMAD 2/3 were positive in a higher proportion of BOS patients compared to RAS cases.

Summary: This study found that HLA mismatch is associated with the development of bronchiolitis obliterans syndrome (BOS), and a decrease in overall survival is only apparent when there are 6 mismatches. HLA-A and -DR mismatches are associated with an increased risk of mortality and BOS development. Lung transplantation offers an extended lifespan and improved quality of life for many patients with advanced refractory lung disease.

Summary: This study analyzed biospecimens from 181 pediatric HCT candidates to investigate the association between pre-HCT pulmonary metatranscriptomes and post-HCT lung injury. The results showed that certain gene expression patterns and microbiome compositions in the lungs prior to transplantation were linked to an increased risk of developing lung injury after the procedure. Data from this study suggest that assessment of pre-HCT BAL fluid could potentially help identify high-risk pediatric HCT candidates who may benefit from targeted interventions.

Summary: This pilot study revealed a significant increase in extracellular IL-26 protein concentration in BAL samples from patients with BOS, but not in samples from patients with AR. Macrophages and lymphocytes were identified as cellular sources of IL-26 protein in BAL cells obtained from BOS patients.
