The Approach to Antibodies After Heart Transplantation

AbstractPurpose of ReviewThis review summarizes recent data about antibodies after cardiac transplantation, what testing modalities are available and how frequently to employ them, and when treatment is necessary.Recent FindingsTechnologies available for antibody detection have progressed over the past couple decades. New and preformed antibodies are associated with worse outcomes in transplant recipients.SummaryThe frequency of screening for post-transplant antibodies and for antibody-mediated rejection (AMR) should be based on risk stratification. The presence of antibodies alone post transplant does not constitute a diagnosis of AMR. Treatment of post-transplant antibodies and AMR should be made in conjunction with consideration of AMR grade and graft dysfunction. Future directions will involve improved detection methods and further understanding of non-HLA antibodies and de novo antibodies in the post-transplant population. Additionally, aggressive efforts are currently underway to provide more therapeutic options.
