Abstract
Objectives
The development of new human leukocyte antigens (HLAs) and donor-specific antibodies (DSAs) in patients are associated with worse outcomes following lung transplantation. The authors aimed to examine the relationship between blood product transfusion in the first 72 hours after lung transplantation and the development of HLA antibodies, including DSAs.Design
A retrospective observational study.Setting
At a single academic tertiary center.Participants
Adult lung transplant recipients who underwent transplantation between September 2014 and June 2019.Interventions
None.Measurements and main results
A total of 380 patients were included in this study, and 87 (23%) developed de novo donor-specific antibodies in the first year after transplantation. Eighty-five patients (22%) developed new HLA antibodies that were not donor-specific, and 208 patients (55%) did not develop new HLA antibodies in the first year after transplantation. Factors associated with increased HLA and DSA development included donor pulmonary infection, non-infectious indication for transplant, increased recipient body mass index, and a preoperative calculated panel reactive antibody value above 0. Multivariate analysis identified platelet transfusion associated with an increased risk of de novo HLA antibody development compared to the negative group (odds ratio [OR; 95% CI] 1.18 [1.02-1.36]; p = 0.025). Cryoprecipitate transfusion was associated with de novo DSA development compared to the negative group (OR [95% CI] 2.21 [1.32-3.69] for 1 v 0 units; p = 0.002).Conclusions
Increased perioperative transfusion of platelets and cryoprecipitate are associated with de novo HLA and DSA development, respectively, in lung transplant recipients during the first year after transplantation.Type

Ian James Welsby
As a practicing cardiothoracic anesthesiologist, I have contributed to the better understanding of the management and of perioperative thrombosis (particularly HIT). This has been as a Duke site PI for the Rare Thrombotic Diseases Consortium led by Dr T.L Ortel and a clinical collaborator with the basic and translational science approach to HIT led by Dr G Arepally. I have also championed novel approaches to dealing with perioperative HIT such as plasmaperesis.
Similarly, I have been a local leader in establishing management of transfusion approaches to major cardiac surgery including the novel introduction of autologous plateletpheresis to limit exposure to allogeneic platelet transfusions in this highly transfused population, identifying the transfusion requirements during thoracic aortic reconstruction and promoting use of a lower dose of rFVIIa use in this population, changing established clinical practice.
My research interests focus on perioperative transfusion and hematology concerns. Recently, Dr Kor (Mayo Clinic) and I received a multiple PI R-01 award to evaluate point-of-care/bedside washing of packed red blood cells to reduce perioperative lung injury. This novel repurposing of commonly available “cell-saver” technology is, for most surgical cases, the only practical means of delivering a washed product, and promises to be a critical advancement in perioperative transfusion medicine. I also have a longstanding interest in the rejuvenation of RBCs to normalize oxygen delivery capacity of transfused RBCs. Such a development will be of tremendous importance to transfusion practice, particularly for highly transfused populations and with current threats to blood banking inventory.
In summary, I have dedicated my research career to improving the outcome of patients undergoing cardiothoracic surgery, understanding perioperative coagulopathy, and optimizing transfusion practice.
