Does recipient work status pre-transplant affect post-heart transplant survival? A United Network for Organ Sharing database review.
Recipient-related factors, such as education level and type of health insurance, are known to affect heart transplantation outcomes. Pre-operative employment status has shown an association with survival in abdominal organ transplant patients. We sought to evaluate the effect of work status of heart transplant (HTx) recipients at the time of listing and at the time of transplantation on short- and long-term survival. ⋯ This study is the first analysis of UNOS STAR data on recipient work status pre-HTx demonstrating: (1) an improvement in post-transplant survival for working HTx candidates; and (2) an association between working pre-HTx and longer post-HTx survival. Given that work status before HTx may be a modifiable risk factor for better outcomes after HTx, we strongly recommend that UNOS consider these important findings for moving forward this patient-centered research on work status. Working at listing and working at HTx are associated with long-term survival benefits. The association may be reciprocal, where working identifies less ill patients and also improves well-being. Consideration should be given to giving additional weight to work status during organ allocation. Work status may also be a modifiable factor associated with better post-HTx outcomes.

α1-Anti-trypsin improves function of porcine donor lungs during ex-vivo lung perfusion.
Ex-vivo lung perfusion (EVLP), a technique for donor lung assessment, also represents a platform for donor lung repair and immunomodulation. α1-Anti-trypsin (A1AT), a medication used to treat emphysema in A1AT-deficient patients, has anti-inflammatory properties and has been shown to attenuate ischemia-reperfusion injury in rat and pig lung transplants. The objective of this study was to determine whether administration of A1AT during EVLP can improve donor lung quality after prolonged hypothermic preservation. ⋯ Treatment of 24-hour-preserved pig donor lungs with A1AT during EVLP resulted in improved physiologic function, reduced pulmonary edema and inflammation and decreased cell death. Our findings suggest that treatment of donor lungs during EVLP with A1AT is a promising strategy to attenuate early lung injury and improve donor lung function before lung transplantation.
