Ultrastructural Changes in Lung Allografts: Endothelial Changes Correlate with Donor Specific Antibody & Antibody Mediated Rejection
M. Alexander, A. Bentall, P. Abell Aleff, J. Scott, A. Roden.
Mayo Clinic, Rochester, MN.
Introduction: Antibody mediated rejection (AMR) causes lung allograft (LA) injury. Challenges with C4d interpretation & lack of specific histological criteria account for difficulty in diagnosing…

Treatment of Post Transplant Hepatitis C (HCV) with Direct-Acting Antiviral (DAA) Agents May Improve Liver Function but Does Not Lead to an Increase in Liver Rejection
P. Sheiner, N. Mello, G. Baixauli, M. Einstein, C. Rochon, Y. Kwon, M. Bejon.
Surgery, Hartford Hospital, Hartford, CT.
Previous studies have suggested that with the use of with (DAA) agents to treat post transplant (HCV), there has been an increased incidence of liver…
