Filter by:The thundering evolution of lung transplantation management during the past ten years and primary graft dysfunction (PGD) new definition have led to new predictive factors of PGD. Therefore, we retrospectively analyzed a monocentric database using a machine-learning method, to determine the predictive factors of grade 3 PGD (PGD3), defined as a PaO2/FiO2 ratio < 200 or being under extracorporeal membrane oxygenation (ECMO) at postoperative day 3. We included all double lung transplantation from 2012 to 2019 and excluded multi-organ transplant, cardiopulmonary bypass, or repeated transplantation during the study period for the same patient. Recipient, donor and intraoperative data were added in a gradient boosting algorithm step-by-step according to standard transplantation stages. Dataset will be split randomly as 80% training set and 20% testing set. Relationship between predictive factors and PGD3 will be represented as ShHapley Additive exPlanation (SHAP) values.
This is a non-interventional cohort study to assess a novel assay to detect excessive or insufficient immunosuppression from the drug tacrolimus in lung transplant recipients. The assay measures mean residual expression (MRE) of genes downstream of nuclear factor of activated T cells (NFAT), a transcription factor regulated by tacrolimus. The investigators will assess whether MRE levels identify subjects at risk for rejection (insufficient immunosuppression) or infection (excessive immunosuppression).
