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)

No Impact of Steroid-Free IS on Graft HCV Fibrosis

Klintmalm Liver Transplant 2011

C.H.B.

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?

Samonakis, J Hepatol 2012 in Press, Berenguer Nat Rev Gastroenterol 2011

C.H.B.

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.

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

• Triple antiviral therapies with IFN in cirrhotics remains difficult

– Increase in SVR expected

– High rate of anemia , risk of sepsis and death

– Strategies to improve tolerance are necessary

– Treatment without IFN are strongly awaited

• First results of triple therapies after LT are encouraging

– Increased virologic response

– Acceptable tolerance and drug-drug interactions manageable

– Treatment without IFN awaited but IFN might remain

necessary in some patients
