The concentration of cfDNA at 1 hour and the change in cfDNA concentration per hour of EVLP in the transplanted and declined groups were compared by univariable and multivariable logistic regression. cfDNA was introduced as an additional factor in a machine-learning algorithm to predict lung utilization and postoperative outcome and the performance evaluated.Results: Significantly higher cfDNA concentrations were observed in the declined group than in the transplanted group (1 hour: p < 0.001; delta/hour: p = 0.031). Multivariable analysis among the 1 hour factors showed that [cfDNA 1 hour] (OR 4.27, p = 0.010) was an independent prognostic factor. Increases in [cfDNA 1 hour], [cfDNA delta/hour], and both showed that both initial [cfDNA] and increases in [cfDNA] over time were independently correlated with the probability of a lung being declined. The validation analysis also confirmed higher [cfDNA 1 hour] in the declined group than in the transplanted group (p = 0.010). Addition of [cfDNA] features improved the performance of a machine-learning algorithm used to predict donor lung utilization.Conclusions: The cfDNA concentration in EVLP perfusate correlates with the rate of decline of lungs for transplant from EVLP.","PeriodicalId":15900,"journal":{"name":"Journal of Heart and Lung Transplantation","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We included adult deceased organ donors after brain death managed in 21 US regions with donor care units (DCUs) January 2019 to December 2022 and their heart recipients. The primary exposure was organ recovery in independent vs hospital-based DCUs. Outcomes included heart graft survival duration (primary) and incidence of heart donation.Results: The cohort captured 9,830 donors after brain death, 3,302 in 10 independent DCUs (33.6%), and 1,366 (13.9%) in 11 hospital-based DCUs (the remainder in hospitals). Unadjusted heart donation did not differ between independent and hospital-based DCUs (40.9% vs 40.4%, p = 0.75). In a logistic regression model including donor factors, odds of heart donation did not differ by DCU type (adjusted odds ratio [aOR] 1.02, 95% confidence interval [CI] 0.86-1.22). Among 3,108 heart transplant recipients from cohort heart donors, restricted mean survival time 4 years after transplant was not different between hearts recovered in independent vs hospital-based DCUs (1,292 vs 1,276 days).

We evaluated the prognostic value of cardiac CT-derived right ventricular ejection fraction (RVEF) in LTx candidates.Methods: This retrospective study included patients who were listed for LTx and underwent cardiac computed tomography (CT) between September 2019 and December 2023. Patients were categorized into 3 groups based on CT-derived RVEF and survival analyses were performed among these groups: normal RVEF (≥45%), mild-to-moderate RV dysfunction (25%-45%), and severe RV dysfunction (<25%).Results: In the 203 patients (median age, 61 years [interquartile range [IQR], 54-64]), the most common indication for LTx was interstitial lung disease (79.3%). Patients were followed for a median duration of 297 days (IQR, 140-632), and the 1-year survival rates were 85.2% for those with normal RV, 69.3% for those with mild-to-moderate RV dysfunction, and 55.6% for those with severe RV dysfunction (p < 0.001). Severe RV dysfunction (hazard ratio [HR] 6.72, p = 0.020), age (HR 1.1, p = 0.010), and 6-minute walking distance (HR 0.62, p = 0.010) were associated with an increased risk of 1-year mortality.Conclusions: Severe RV dysfunction identified on cardiac CT was a significant prognostic factor for 1-year mortality in LTx candidates. Patients with severe RV dysfunction should be prioritized for LTx and classified as urgent due to their elevated short-term mortality risk. Cardiac CT may provide valuable prognostic information during the pretransplant evaluation process.","PeriodicalId":15900,"journal":{"name":"Journal of Heart and Lung Transplantation","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143457528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the breadth of reactivities against self-antigens and their association with CLAD has been underexamined. In a single-center study, we screened lung transplant (LTx) recipients for novel autoantibodies at transplant and 6 months post-LTx, assessed dnDSA exposure, and CLAD-free survival.Methods: Serum samples were collected from 89 crossmatch-negative bilateral LTx recipients at the time of LTx and 6 months post-LTx, before a CLAD diagnosis, for autoantibody screening using a custom antigen microarray.Results: Patients who developed CLAD by 5 years post-LTx demonstrated a decrease in average IgG reactivity, but no decrease in IgM reactivity when measured at 6 months post-LTx. IgG anti-tropoelastin, SP-D, and thyroglobulin autoantibodies were significantly elevated 6 months post-LTx in patients who developed CLAD by 5 years, compared to those who remained CLAD-free at 5 years. In contrast, patients who remained CLAD-free at 5 years had elevated levels of IgG anti-CENP-B at both timepoints and PM/SCL100 at 6 months post-LTx, suggesting these may confer protection. Exposure to autoantibodies against lung-enriched targets and dnDSA conferred increased CLAD risk.Conclusions: We identified novel autoantibodies associated with CLAD-free survival, bolstering the independent relationship between autoantibodies and CLAD. We also identified autoantibody signatures that are associated with a marked increase in CLAD risk. Exposure to lung-enriched targets and dnDSA may have a reciprocal amplifying effect that lies on a tissue-specific mechanistic pathway leading to CLAD.","PeriodicalId":15900,"journal":{"name":"Journal of Heart and Lung Transplantation","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143457557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional Chinese medicine (TCM) ingredients are promising but poorly studied in LTx. This study aimed to identify potential ingredients and elucidate their mechanisms.Methods: Ten TCM ingredients, including (-)-epigallocatechin-3-gallate, quercetin, wogonin, triptolide, berberine, fisetin, coumestrol, luteolin, nobiletin, and baicalein, were identified as promising candidates using a network pharmacology approach. All the candidates were tested for their ability to improve clamp-induced IRI. Multiple-dose validation was conducted in LTx models, with a focus on baicalein. The pharmacological efficacy of baicalin was verified in an ex-vivo rat lung perfusion model.Results: All ten TCM ingredients improved clamp-induced IRI. Multiple-dose validation confirmed that baicalein mitigated IRI-induced graft damage and dysfunction. Baicalein reduced the elevated levels of advanced glycation endproducts (AGEs) and their downstream pathogenic effects induced by IRI. Exogenous AGEs counteracted the therapeutic effect of baicalein. Baicalein inhibited AGE formation by modulating glucose oxidation rather than polyol metabolism.Conclusions: This study provides a laboratory foundation for the use of TCM ingredients in the treatment of IRI in LTx.","PeriodicalId":15900,"journal":{"name":"Journal of Heart and Lung Transplantation","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143425578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
