Purpose: Epstein-Barr virus (EBV) has been implicated in a multitude of cancers, including B-cell lymphoma, Burkitt's lymphoma, CNS lymphoma, gastric cancer and nasopharyngeal carcinoma. Previous research has suggested that EBV mismatch (donor positive/recipient negative) is a risk factor for the subsequent development of malignancy. We assessed whether EBV mismatch (D+/R-) is correlated with a higher incidence of cancer and worse outcome in heart transplant (HTx) patients (pts)
Methods: Between 2010-14, we assessed 336 HTx pts. This group was divided into pts with EBV mismatch (D+/R-, n=9) and pts without EBV mismatch (n=327). Endpoints included 3-year survival, 3-year freedom from post-transplant malignancy, 3-year freedom from cardiac allograft vasculopathy (CAV) (≥30% angiographic stenosis), 3-year freedom from non-fatal major adverse cardiac events (NF-MACE: myocardial infarction, new congestive heart failure, percutaneous coronary intervention, implantable cardioverter defibrillator/pacemaker implant, stroke), and 3-year freedom from any-treated rejection (ATR), acute cellular rejection (ACR) and antibody-mediated rejection (AMR).
Results: Pts with EBV mismatch had a significantly reduced 3-year survival (66.7% vs 88.4%, p=0.031). 3/3 pts who died in the EBV mismatch group died from heart failure. The 3-year freedom from post-transplant malignancy was 100.0% in the EBV mismatch group. There was no significant difference in 3-year freedom from CAV, NF-MACE, ATR, ACR, or AMR.
Conclusion: EBV mismatch appears to lead to increased mortality post-transplant. There is no increased risk for rejection, CAV, NF-MACE or the development of post-transplant malignancy in this population. Larger studies are warranted to confirm these findings and reconcile mechanisms of poor outcome.
