Liver Biopsy Gold Standard, Bring additional
information than fibrosis stage. HPVG
Invasive, can be done with liver biopsy Not
routine for many Centres. Non invasive
tests Biochemical Elastometry (fibroscan).

STEROIDS AND HCV
  • Controversial role
  • Increase viral load (Fong Gastro 1994, Gane
    Gastro 1996)
  • Increase viral hepatocyte entry (Gastro 2010)
  • Boluses of steroids deleterious (Berenguer J
    Hepatol 2000)
  • Rapid withdrawal deleterious (Berenguer
    Hepatology 2003, McCaughan J Hepatol 2004,
    Vivarelli J Hepatol 2007)
  • Immune rebound?
  • Immunosuppression without steroids not yet
    proven beneficial (Klintmaln Liver Transplant
    2007)

HCV Recurrence , Cyclosporine vs Tacrolimus
  • There is currently no proof of superiority of one
    vs another
  • Antiviral effect of Cyclosporine only in vitro
  • Better efficacy of IFN in Ciclosporine patients
    not confirmed
  • Randomized studies showed earlier reinfection
    with Tac but no difference in fibrosis stage,
    better survival with Tac?

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

20
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.

Direct Antiviral Agents Before LTA New Challenge
  • Data In cirrhotic patients are lacking
  • Therapies with IFN will remain poorly tolerated
  • Increase possibility to achieve SVR or on
    treatment virologic response
  • Increase risk of virologic breakthrough
  • Duration, safety issues to be analysed
  • Therapies without IFN awaited

Direct Antiviral Agents After LTA New Challenge
  • Increase possibility to achieve SVR or on
    treatment virologic response
  • Interaction between anti NS3 protease and
    calcineurin inhibitors
  • Duration, safety issues to be analysed
  • Therapies without IFN awaited

Telaprevir and Cyclosprine and Tacrolimus
Interactions
Cmax increased by 1.4X AUC Increased by

Cmax increased by 9.3X AUC Increased by 70X T1/2
increased by 5 X

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

45
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
