Session 4: Whats new in Transplant ID Transplanting the HBV/HCV positive patient Transplant Infectious Disease Conference 2015 Cancun, October 13, 2015 I have financial relationship(s) within the last 12 months relevant to my presentation with: Abbvie, BMS, Gilead, Janssen AND My presentation does not include discussion of off-label or investigational use I do not intend to reference unlabeled/unapproved uses of drugs or products in my presentation. Marina Berenguer, MD La Fe University Hospital and Ciberehd, Valencia, Spain TID 2015 Liver Transplant Spanish Registry: HCV vs Other indications Wilcoxon Test p < 0,001 yrs 70% 59% Cirrhosis HCV Yes (3284) No (4595) Graft survival HCV (3284) no-HCV (4595) 1 m 3 m yrs Memoria del RETH 2008, Sociedad Espaola de Trasplante Heptico Adults/ No HCC / Elective LT / Benefits of antiviral therapy HCV eradication leads to improvements in outcome Berenguer M et al.

Pre vs post-LT therapy Why should we treat pre-transplant? Prevent HCV recurrence post-liver transplant Prevent death while the patient is on the waiting list Potentially reduce the need for liver transplant Open up access to marginal donors Pre-liver transplantation therapy for HCV Patients treated for >30 days pre-transplant are likely to avoid HCV recurrence post-transplant Curry MP, et al. Gastroenterology 2015;148:1007. *Wilcoxon rank sum test.

Different profile of antiviral drugs---treatment adherence Fundamental concepts for individualized prophylaxis 1. Sustained viral suppression essential Persistence of DNA in intra & extrahepatic sites 2. Different risk of HBV recurrence (non-replicators vs replicators) Strategies to maximize cost-benefit 1- Dose reductions of HBIg 2- Discontinuation of HBIg followed by antiviral therapy 3- Prophylaxis with antiviral therapy without HBIg 4- Discontinuation of HBV prophylaxis 5- HBV vaccination Rates of HBV Recurrence According to First Year HBIg Doses (with LAM) F. Villamil (used with permission) 150, , , ,000 50, ,000 3 log or drug-resistant species? cccDNA in liver tissue? # Recurrent HBV disease 2- What are the clinical implications of HBV recurrence? (potent antivirals era) No cases of FCH in > 10 years Recurrence easily manageable--effective antiviral rescue tx Strict monitoring ----ensure prompt initiation of antiviral tx Individualized prophylaxis against HBV recurrence High Risk HBV DNA 10 4 IU/ml R. mutants Adherence issues HDV (tx options limited) HIV Low Risk Undetectable DNA HBeAg (-) at LT Wild HBV Predicted compliance Low-dose HBIG + NUC long-term combination Selection of NUC based on drug-resistance profile HBIG Minimization strategies Need of HBIg? (mini- short duration?) Strict monitoring
