22 Conclusions When to initiate antiviral therapy? Pre transplant HCV cirrhosis and HCC: 2-3 months before transplantation Pre transplant decompensated cirrhosis: at listing Post transplantation: no emergency (apart fibrosing cholestatic hepatitis) 6 mo-1y after transplantation Fibrosis F2 not justified Which therapy? Pre transplant HCV compensated cirrhosis and HCC, non 3 genotype Sofo + ledi + riba ou sofo + dacla + riba Ombitasvir + paritaprevir + ritonavir? Pre transplant HCV compensated cirrhosis and HCC, genotype 3 Sofo + dacla + riba Pre transplant decompensated HCV cirrhosis Sofo + ledi ou sofo + dacla (G3) Post transplant Sofo + ledi + riba ou sofo + dacla + riba (G3)

23 For how long? Conclusions Careful approach = 24 weeks 12 weeks: possibly enough with ribavirin Mistakers to be avoided: Protease inhibitors in patients with Child B or C cirrhosis Protease inhibitors post transplantation Except careful monitoring of calcineurin inhibitors Continue post transplant if therapy initiated 2 months pre transplant and HCV-RNA undetectable at the time of transplant Treating a patients with compensated cirrhosis and «uncontrolled» HCC

24 Conclusions What can be expected? Prevent post transplant recurrence Avoid progression of HCV recurrence Cirrhosis, graft loss, retransplantation Clinical improvement with the possibility for delisting Slow the progression of HCC? Decrease the rate of recurrence of HCC? Decrease the number of transplantations for HCV cirrhosis ± HCC No reduction in the total number of transplantations (in Western coutries)
