Efficacy of 8- versus 12-week treatment with ledipasvir/sofosbuvir in chronic hepatitis C patients eligible for 8-week regimen in a real-world setting.

Introduction: Non-cirrhotic treatment-naive hepatitis C patients infected with genotype 1 can be treated with ledipasvir/sofosbuvir (LDV/SOF) for 8 weeks, but in practice this regimen is frequently extended up to 12 weeks at least in part due to insufficient real-world data supporting shortening of treatment. The aim of our study was to compare 8- and 12-week regimens' efficacy in patients eligible for 8-week therapy in a real-world setting. Material and methods: Data of HCV genotype 1 infected patients treated with LDV/SOF between 2015 and 2018 included in the EpiTer-2 database were analyzed with respect to patients' characteristics and length of treatment. Results: Among a total of 1718 patients treated with LDV/SOF, 679 were included in the analysis, 238 (35%) received 8-week regimen, whereas 441 were treated for 12 weeks although they fulfilled the criteria for a shorter course. The majority of patients were infected with genotype 1b (89%) and demonstrated minimal fibrosis (55%). The 12-week regimen was assigned significantly more frequently to patients with comorbidities, concomitant medications and advanced liver fibrosis. The sustained virologic response rate was similar after 8 (98%) and 12 (97%) weeks of therapy according to intent-to-treat analysis and reached 99% in both groups after exclusion of patients lost to follow-up. Conclusions: We confirmed high effectiveness regardless of treatment duration with LDV/SOF in non-cirrhotics infected with HCV genotype 1 eligible for the 8-week regimen according to the current label. This real-world study also demonstrated no need for addition of ribavirin (RBV) in this population and showed that shortening of treatment significantly improves the safety profile of LDV/SOF medication.

Hepatitis B virus treatment in hepatocellular carcinoma patients prolongs survival and reduces the risk of cancer recurrence.

Chronic hepatitis B virus (HBV) infection and HBV-related liver disease are estimated to affect about 240 million people worldwide. Now that a vaccine is available, the number of new HBV infection cases has plummeted. Yet, there are still regions with very high incidence of HBV. Hepatocellular carcinoma (HCC) is the fourth to six most common malignancy in men and the ninth most common malignancy in women worldwide. 54% of all HCC cases are HBV-associated, making it the most common cause of cancer worldwide. Hepatitis B therapy prevents progression of chronic hepatitis to cirrhosis and HCC development, but even with the best HBV treatment, such patients are still at risk of HCC. Also in patients after transarterial chemoembolization (TACE), liver resection (hepatectomy) or liver transplant, suppression of hepatitis B virus (HBV) improves patient survival. In this paper we present current possibilities of HCC and HBV treatment, which lead to improved survival and quality of life.

The influence of anti-HBc status on the sustained virological response rate in HCV-infected patients treated with pegylated interferon alfa 2 and ribavirin.

AIM OF THE STUDY: To determine the influence of HBsAg and HBeAg negative but anti-HBc positive status on the sustained virological response (SVR) rate in HCV-infected patients treated with pegylated interferon alfa 2 (Peg-IFNα-2) and ribavirin (RBV). MATERIAL AND METHODS: The study was based on the retrospective analysis of medical records of HCV-infected patients who started Peg-IFNα and RBV treatment between 1 January 2011 and 31 December 2013 at the 1st and 2nd Department of Infectious Diseases of the Regional Hospital in Wroclaw, Poland. RESULTS: Among 240 patients included in the analysis 99 were anti-HBc positive and 141 anti-HBc negative. In the genotype 1, anti-HBc positive group the SVR rate was 47% and in the anti-HBc negative group it was 42.7% (p = 0.591). In the genotype 3, anti-HBc positive group the SVR rate was 60% and in anti-HBc negative patients it was 63.2% (p = 0.79). Differences in SVR rates between anti-HBc positive and negative groups were not statistically significant. None of the anti-HBc positive patients developed reactivation of HBV infection during or in the 24 weeks following the end of treatment. CONCLUSIONS: Anti-HBc determination does not seem to be useful in predicting treatment outcome of conventional Peg-IFNα/RBV therapy in patients infected with HCV genotypes 1 and 3.
