RESUMO

BACKGROUND AND AIMS: Direct antiviral agents (DAAs) have revolutionised the standard of care for the treatment of hepatitis even in patients with hemoglobinopathies. The aim of this study is to show how, thanks to DAAs, HCV infection has been substantially eradicated in one of the biggest Centres for the management of Thalassemia in Europe. METHODS: Thalassemia major patients regularly transfused and iron chelated in Cagliari (Italy) who were HCV-RNA positive were evaluated for the potential prescription of antiviral therapy. RESULTS: A total of 99 patients, 26 of whom had been diagnosed with cirrhosis, were treated with at least one dose of DAAs, which proved to be safe and well tolerated. Two of the patients died during the treatment after becoming HCV-RNA negative while another voluntarily interrupted the therapy. The final SVR in the patients who completed the treatment was 100%, while measuring 97% (96/99) in the Intention-to-Treat analysis. After DAAs, no new cases of hepatocellular carcinoma have been reported. CONCLUSIONS: The use of DAAs in patients suffering from beta-Thalassemia major with chronic hepatitis C or cirrhosis can be considered safe and effective. Close monitoring for hepatocellular carcinoma development is, in any case, recommended indefinitely post-SVR.

RESUMO

Progression of liver fibrosis in patients with hemoglobinopathies is strongly related to the severity of iron overload and the presence of chronic hepatitis C virus (HCV) infection. Effective iron chelation therapy and HCV infection eradication may prevent liver complications. The European Association for the Study of the Liver guidelines recommend interferon-free regimens for the treatment of HCV infection in patients with hemoglobinopathies. However, data regarding the use of direct-acting antiviral drugs (DAAs) in this patient population are few. This observational study evaluated the safety and efficacy of therapy with DAAs in an Italian cohort of patients with hemoglobinopathies, chronic HCV infection and advanced liver fibrosis. Between March 2015 and December 2016, 139 patients received DAAs and completed 12 weeks of follow up after the end of treatment for the evaluation of sustained virological response (12SVR). The 12SVR (93.5%) was comparable with that typically observed in cirrhotic patients without hemoglobinopathies. Three patients died during the period of observation of causes unrelated to DAAs. One patient did not achieve a virological response and five (3.6%) relapsed during 12 weeks of follow-up after the end of therapy. In addition, patients showed significant reductions in serum ferritin at 12 weeks to levels similar to those observed in a control group of 39 patients with thalassemia major without HCV infection, who adhered to chelation therapy and had no overt iron overload. In conclusion, the use of DAAs appears to be safe and effective in patients with hemoglobinopathies and advanced liver disease due to HCV.

RESUMO

BACKGROUND: Rapid and early virological responses to peginterferon-alpha and ribavirin are predictive of sustained virological response (SVR) in hepatitis C virus (HCV) infection. We aimed at finding a simple rule to determine the shortest duration of dual therapy for all HCV genotypes, obtained by multiplying time to Initial Viral Response, IVR (first undetectable HCV-RNA) by 4 (Tailored Therapy-4, or TT4). METHOD: 267 naïve HCV-infected patients with compensated liver disease were randomized (2:1) to the TT4 (n=180) or current standard-of-care (SoC, n=87) and received peginterferon-alpha plus ribavirin. Patients with HCV-RNA decrease ≤2log10 at week 12 or detectable HCV-RNA at week 24 discontinued treatment. RESULTS: Both groups had comparable baseline characteristics, SVR rates were similar in the whole population (60.6% vs. 60.9%) and within each genotype subgroup (G1: 46.6% vs. 55.6%; G2: 90.2% vs. 94.4%; G3: 74.1% vs. 58.3%; G4: 45.8% vs. 33.3%). Relapse rate was higher in G1-TT4 than G1-SoC. Treatment duration in SVR patients was shorter in TT4 compared to SoC, both overall [25±15 vs. 36±12.1 weeks], and for subgroups: G1 [35.3±16.7 vs. 47.3±2.6 weeks], G2 [18.3±7.5 vs. 24±2.8 weeks], G3 [15.2±8.7 vs. 22.8±3 weeks] and G4 [26.9±13 vs. 48 weeks]. CONCLUSIONS: In HCV-naive patients, TT4-rule treatment yields similar SVR rates compared to SoC but with shorter treatment duration and remarkable cost reduction.
