Peg-IFN and ribavirin treatment for recurrence of genotype 2 and 3 hepatitis C after liver transplantation

No need to discontinue hepatitis C virus therapy at the time of liver transplantation

Objectives

Direct antiviral agents (DAA) has dramatically improved the therapy outcome of hepatitis C-virus (HCV) infection, both on the waiting-list and post liver transplantation (LT). DAA are generally well-tolerated in patients with mild to moderate liver and kidney failure, but some DAAs are contraindicated in patients with severe dysfunction of these organs. Today there are few studies of peri-LT DAA use and treatment is commonly discontinued at the time of LT. We report here our experience of DAA therapy given continuously in the perioperative LT period in a real-life setting in Sweden.

Material

In total 10 patients with HCV-cirrhosis, with or without hepatocellular carcinoma, and a median age of 60.5 years (range, 52–65) were treated with DAAs on the waiting list for LT, and continued in the early postoperative period without any interruption, on the basis of not having reached a full treatment course at the time of LT. Sofosbuvir and a NS5A inhibitor with or without ribavirin, or sofosbuvir and ribavirin only, were given. The distribution of genotypes was genotype 1 and 3, in 4 and 6 patients, respectively. Six of the 10 patients had previously been treated with IFN-based therapy.

Results

There were no adverse events leading to premature DAA discontinuation. All recipients achieved a sustained viral response 12 weeks after end-of-treatment (SVR12). At the time of LT the median MELD-score was 16.5 (range 7–21), CTP-score 9.0 (range 5–10), creatinine 82.5 μmol/L (range 56–135, reference 60–105), bilirubin 33 μmol/L (range 16–79, reference 5–25) and PK-INR 1.5 (range 1.1–1.8). The median duration of DAA therapy was 60 days (range 18–132) pre-LT, 54 days post-LT (range 8–111 days) and in total 15.5 weeks (range 12–30 weeks).

Conclusion

Interferon-free DAA therapy of HCV-infection given in the immediate pre- and post-operative LT period is safe, well-tolerated and yields high SVR rates.

INF-free sofosbuvir-based treatment of post-transplant hepatitis C relapse - a Swedish real life experience

BACKGROUND

Relapse of hepatitis C virus (HCV) infection after liver transplantation has been universal, and the fibrosis progression faster than in non-transplanted patients. Interferon (IFN)-free treatment with direct antiviral agents (DAA) has improved the treatment outcome dramatically. We here report on the outcome of IFN-free treatment for HCV relapse after liver transplantation in a real life setting in Sweden.

MATERIAL

In total, 93 patients with a mean age of 60 years (range 32-80) with HCV relapse after liver transplantation were given sofosbuvir-based treatment in combination with a protease inhibitor (simeprevir) or a NS5A inhibitor (daclatasvir or ledipasvir) with or without addition of ribavirin (RBV), or sofosbuvir and RBV only. Treatment was generally given during 24 weeks for advanced fibrosis or cirrhosis cases and 12 weeks for mild fibrosis with fibrosis stage 2 or less. The distribution of genotype 1, 2, 3, 4 in our patients was 58, 7.5, 26.5 and 7.5%, respectively.

RESULTS

All recipients reached end-of-treatment response (ETR) with HCV RNA <15 IU/mL. Sustained viral response 12 weeks after treatment cessation (SVR12) was achieved in 91/93 (97.8%) recipients. The SVR12 rates for genotype 1, 2, 3 and 4 were the SVR12 rate were 96, 100, 100 and 100%, respectively (p = .04).

CONCLUSION

It is concluded that IFN-free treatment with DAAs for HCV relapse after liver transplantation is highly effective also in a real life setting and offers cure for most recipients.

Community-based seroepidemiological survey of HCV infection in Catalonia, Spain

In a recent expert meeting, Swedish recommendations for the treatment of HCV infection were updated. An interferon-free combination of direct-acting antiviral agents was recommended as the first line standard-of-care treatment for chronic HCV infection. Interferon-based therapy should be considered as a second line option after an individual benefit-risk assessment. Treatment is strongly recommended for HCV infected patients with bridging fibrosis or cirrhosis (Metavir stages F3–4), before and after liver transplantation, and in the presence of extra-hepatic manifestations. Additionally, patients with moderate liver fibrosis (stage F2) as well as women in need of in vitro fertilisation should be prioritised for therapeutic intervention. Treatment indications for people who inject drugs, children, chronic kidney disease and HIV co-infection are also discussed.
