Update V1 White

To celebrate the 10th anniversary of the DoI, which was created in 2008, a draft new edition of the DoI has been prepared by a multidisciplinary working group with 39 members. The group has reviewed the original DoI in the light of persisting and emerging issues relating to organ trafficking and transplant tourism, and made changes which are intended to ensure that the DoI offers clear guidance for health professionals and policy makers.

A Comparison of HLA Molecular Mismatch Methods to Determine HLA Immunogenicity [published online February 13, 2018]

Wiebe C, Kosmoliaptsis V, Pochinco D, Taylor C, Nickerson P..
Transplantation. doi: 10.1097/TP.0000000000002117.

The authors present the first comparison of available scoring systems to assess HLA donor-recipient mismatches and their correlation with the development of de novo donor-specific antibody (dnDSA) in kidney transplant recipients on active immunosuppression. The authors determined HLA-DR and DQ molecular mismatches at the molecular level comparing 3 different methods: an eplet analysis that identifies small patches of surface exposed mismatched amino acids, an amino acid mismatch scoring physicochemical properties of all mismatched amino acid sequence polymorphisms, and an electrostatic mismatch that assesses the HLA tertiary structure for unique electrostatic potential profiles. The authors tested those methods in 596 renal transplant recipients and correlated their results with the development of HLA-DR/DQ dnDSA´s. Authors demonstrate a good correlation among the 3 scoring systems (R2=0.85-0.96). Importantly, HLA-DR and DQ free survival after kidney transplantation equally correlated with Eplet, amino acid and electrostatic mismatches (p<0.0001). Notably, all 3 methods predicted the development of dnDSA in a multivariate analysis after adjustment for recipient age, immunosuppression, and nonadherence, thus providing precise methods of alloimmune risk assessment.

Johns Hopkins doctors successfully transplant hepatitis C-infected kidneys into virus-free patients

March 6 - In a small study, doctors at Johns Hopkins have successfully transplanted 10 hepatitis C-infected kidneys into patients without hepatitis C and prevented the patients from becoming infected by hepatitis C. The success of these transplants could mean more organs being available for the nearly 100,000 people in the U.S. currently waiting for a kidney transplant.

NIH Blog: Snapshots of Life: Finding Where HIV Hides

Researchers have learned a tremendous amount about how the human immunodeficiency virus (HIV), which causes AIDS, infects immune cells. Much of that information comes from studying immune cells in the bloodstream of HIV-positive people. Less detailed is the picture of how HIV interacts with immune cells inside the lymph nodes, where the virus can hide. In this image of lymph tissue taken from the neck of a person with uncontrolled HIV infection, you can see areas where HIV is replicating (red) amid a sea of immune cells (blue dots). Areas of greatest HIV replication are associated with a high density of a subtype of human CD4 T-cells (yellow circles) that have been found to be especially susceptible to HIV infection.

The Impact of Liver Graft Injury on Cancer Recurrence Posttransplantation.
Li CX, Man K, Lo CM. 
Transplantation. 2017 ;101(11):2665-2670.

This review article summarizes the latest findings on the impact of ischemia reperfusion injury and organ quality on tumor recurrence, mainly HCC after liver transplantation (LT). The authors characterize specific risks linked to graft types, eg living donor livers, donation after circulatory death or steatotic grafts. Focus of this review are underlying mechanisms that promote HCC recurrence following LT. The authors provide a very detailed analysis not only on the cellular inflammatory response, involving the microenvironment of the liver, but also on tumor cell migration and invasion promoted by an impaired microcirculation. The review also includes an analysis on the impact of reperfusion injury including hypoxia and angiogenesis on tumor cell aggressiveness. Finally, reactive progenitor cell recruitment and mobilization of other immune cells promoting tumor recurrence in a later phase after LT are highlighted. Overall, the link between reperfusion injury and tumor recurrence is a most relevant clinical problem. Novel preservation strategies in liver transplantation may provide additional relevant insights and treatment options.
