    Residual low HDV viraemia is associated HDV RNA relapse after PEG-IFNa-based antiviral treatment of hepatitis delta: Results from the HIDIT-II study
    (Wiley, 2020) Bremer, Birgit; Anastasiou, Olympia E.; Hardtke, Svenja; Caruntu, Florin Alexandru; Curescu, Manuela G.; Yalçın, Kendal; Akarca, Ulus S.; Gürel, Selim; Zeuzem, Stefan; Erhardt, Andreas; Luth, Stefan; Papatheodoridis, George, V.; Radu, Monica; Idilman, Ramazan; Manns, Michael P.; Cornberg, Markus; Yurdaydın, Cihan; Wedemeyer, Heiner
    The role of low levels of HDV-RNA during and after interferon therapy of hepatitis D is unknown. We re-analysed HDV RNA in 372 samples collected in the HIDIT-2 trial (Wedemeyer et al, Lancet Infectious Diseases 2019) with the Robogene assay (RA; Jena Analytics). Data were compared with the previously reported in-house assay (IA). We detected HDV-RNA in one-third of samples previously classified as undetectable using the highly sensitive RA. Low HDV viraemia detectable at week 48 or week 96 was associated with a high risk for post-treatment relapse, defined as HDV RNA positivity in both assays at week 120. HDV RNA relapses occurred in 10/15 (67%) patients with detectable low HDV RNA at week 48 and in 10/13 (77%) patients with low viraemia samples at week 96. In contrast, the post-treatment relapse rate was lower in patients with undetectable HDV RNA in both assays during treatment.

    Ten-year follow-up of a randomized controlled clinical trial in chronic hepatitis delta
    (Wiley, 2020) Wranke, Anika; Hardtke, Svenja; Heidrich, Benjamin; Dalekos, George; Yalçın, Kendal; Tabak, Fehmi; Gürel, Selim; Çakaloglu, Yılmaz; Akarca, Ulus S.; Lammert, Frank; Haeussinger, Dieter; Mueller, Tobias; Woebse, Michael; Manns, Michael P.; İdilman, Ramazan; Cornberg, Markus; Wedemeyer, Heiner; Yurdaydın, Cihan
    Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis. PEG-interferon alpha-2a (PEG-IFN alpha-2a) is the only effective treatment but its long-term clinical impact is unclear. The aim of this study was to investigate the long-term outcome after 48 weeks of pegylated interferon alpha-2a therapy. We performed a retrospective follow-up study of the Hep-Net-International-Delta-Hepatitis-Intervention-Study 1 (HIDIT-I trial). Patients had received 48 weeks of treatment with either PEG-IFN alpha-2a plus adefovir dipivoxil (ADV) (Group I), PEG-IFN alpha-2a alone (Group II) or adefovir dipivoxil alone (Group III). Liver-related complications were defined as liver-related death, liver transplantation, liver cancer and hepatic decompensation defined as development of Child-Pugh scores B or C or an increase in Model for End-stage Liver Disease (MELD) scores of five or more points in relation to baseline values. Patients were considered for further analysis when they were retreated with PEG-IFN alpha-2a. Follow-up data (at least 1 visit beyond post-treatment week 24) were available for 60 patients [Group I, (n = 19), Group II (n = 20), Group III (n = 21)]. Mean time of follow-up was 8.9 (1.6 - 13.4) years. 19 patients were retreated with IFN-based therapy: 42% (n = 8) in PEG-IFN alpha-2a arms and 58% (n = 11) in the adefovir only arm. Clinical complications on long-term follow-up occurred in 17 patients and were associated with nonresponse to therapy and baseline cirrhosis. The annual event-free survival rate in patients with cirrhosis vs noncirrhotic patients at year 5 and 10 was 70% vs 91% and 35% vs 76%. Long-term follow-up of a large randomized clinical trial suggests that off-treatment HDV RNA response to PEG-IFN alpha-2a treatment leads to improved clinical long-term outcome.
