ANTIVIRAL TREATMENT BEFORE LIVER TRANSPLANTATION – Difficult to manage in decompensated cirrhotic patients – Risk of deterioration of liver function – Risk of sepsis, severe neutropenia, and anemia – Poor antiviral effect at this stage – However, some patients candidates to LT: » Have preserved liver function (those with HCC) » Have a long expected waiting time for LT » Have never been treated or are ”false” non responders C.H.B. ANTIVIRAL TREATMENT BEFORE LIVER TRANSPLANTATION » 124 patients • 56 Child A, 45 Child B, 23 Child C • 86 Genotype 1, 16 Genotype 2, 17 Genotype 3 » SVR: • 50% in genotype non-1, • 13% in genotype 1 » 22 complications in 15 patients ( 21 in Child B and C), 4 died » No HCV recurrence in sustained responders.

CONCLUSION • Survival still affected by HCV recurrence • Monitoring combining liver biopsy and non invasive methods • Treatment before Transplantation poorly effective – SVR before LT , no recurrence post-LT – HCVRNA negativity at LT, Risk of post transplant recurrence reduced by 70% • Treatment after transplantation : – Effective at time of Chronic hepatitis before the F3 stage » 30-40% SVR in G1 Patients » 70% SVR in G2-G3 Patients C.H.B. CONCLUSION • Advent of Direct antiviral agents will open a new era • Before LT: Presence of IFN in the treatment arm will remain a limitating factor • After LT: new strategies will arise • Viral breakthrough, tolerance, interaction with calcineurin inhibitors, treatment duration: – Open questions for the close future C.H.B.
