    Long-Term Immunosuppression Adherence After Kidney Transplant and Relationship to Allograft Histology.

    E. Lorenz, B. Smith, F. Cosio, N. Shah, P. Groehler, J. Verdick, W. Park, M. Stegall.

    Mayo Clinic, Rochester

    Background: Loss of Medicare coverage for immunosuppression 3 years after kidney transplant may be associated with increased nonadherence. The goal of this study was to…

    Clinical and Pathologic Characteristics of Acute Rejection After Alemtuzumab Induction in Kidney Transplant Recipients.

    P. Zhang,1 H. Amer,2 C. Schinstock,2 M. Alexander,1 F. Cosio,2 M. Stegall,3 L. Cornell.1

    1Anatomic Pathology, Mayo Clinic, Rochester; 2Nephrology, Mayo Clinic, Rochester; 3Transplant Surgery, Mayo Clinic, Rochester

    Background: Alemtuzumab induction (AZI) can be used for early steroid withdrawal in kidney transplant (KTx) recipients. There is evidence that AZI-induced lymphocyte depletion leads to…

    Digital Image Analysis of Pediatric Liver Allograft Biopsies Correlates with METAVIR Fibrosis Score.

    R. Fischer,1 S. Foster,2 J. Daniel,1 R. Hendrickson,1 W. Andrews,1 A. Kats.1

    1Children's Mercy Hospital, Kansas City, MO; 2University of Kansas Medical Center, Kansas City, KS

    Background: Serial surveillance biopsies demonstrate post-transplant inflammation and fibrosis in long-surviving pediatric liver allografts. These changes can ultimately lead to cirrhosis and graft failure. However,…
