Abstract: Hepatitis C virus infection causes approximately 4 million new infections worldwide, and 399 000 deaths due to its complications, cirrhosis and hepatocellular carcinoma (HCC). Microenvironmental changes, chronic inflammation, oxidative stress, endoplasmic reticulum stress caused by HCV infection, via genetic and epigenetic changes can result in primary liver cancer during decades. The direct oncogenic property of HCV is wellknown. The transforming effect of four HCV proteins (core, NS3, NS4B, NS5A) has been proven. Effective antiviral therapy, sustained viral response decreases the HCV-related general and liver-related mortality. Interferon-based therapy reduces the risk of HCC development. Shorter therapy with direct acting antiviral agents (DAA) has higher efficacy, fewer side-effects. Publications have reported the unexpected effects of DAA. The authors review the articles focusing on the occurrence of HCC in connection with DAA therapies. There is a need for prospective, multicentric studies with longer follow-up to examine the risk of HCC formation. After antiviral therapy, HCC surveillance is of high importance which means abdominal ultrasound every 3–6–12 months in sustained viral response patients as well. Orv Hetil. 2019; 160(22): 846–853.

Viral Response

Background & Aims: Smoking has multiple effects on factors influencing hepatitis C and antiviral therapy, including lipid metabolism, fibrosis, platelet count and adherence aspects. The aim of this analysis was to determine the impact of smoking on hepatitis C virus antiviral therapy. Methods: Data of two cohorts of an observational multicenter study including therapy-naïve patients infected with genotype 1 hepatitis C virus (HCV) treated with dual antiviral therapy (n=7,796) with pegylated interferon alpha 2a in combination with ribavirin, or triple antiviral therapy (n=1,122) containing telaprevir or boceprevir, were analysed. Results: In the univariate matched pair analysis of dual antiviral therapy patients (n=584), smoking was significantly associated with lower sustained viral response rates (p=0.026, OR 0.69 CI: 0.50 – 0.96). The effect of smoking on sustained viral response remained significant (p=0.028, OR 0.67 CI: 0.47 – 0.96) in the multivariate analysis when adjusting for all other baseline parameters with a significant association in the univariate analysis, i.e. diabetes, fibrosis, body mass index, transaminases and baseline viral load. Under protease inhibitors the influence of smoking on virological response did not arise. Conclusions: Smoking has a negative impact on antiviral therapy in naïve patients infected with HCV genotype 1 independently of age, gender, history of drug use or alcoholic liver disease. The effects of smoking might be overcome by the new antiviral agents.Abbreviations: APRI: AST to platelet ratio index; DAA: direct antiviral agent; DT: dual antiviral therapy; EoTR: end of treatment response; RVR: rapid virological response; EVR: early virological response; HCV: hepatitis C virus; IFN: interferon alpha; MPA: Matched Pair Analysis; NS: non-smokers; PEG-IFN: pegylated interferon alpha 2a; PI: protease inhibitor; RBV: ribavirin; SAE: serious adverse event; SOC: standard of care; S: smokers; SVR: sustained viral response.

Abstract Background Hepatitis C virus virus is global health burden and major health hazard in Egypt, since the virus is the etiological factor of chronic hepatitis. Hepatitis C virus (HCV) accounts for approximately 15%-20% cases of acute hepatitis. After acute infection, around 50% to 80% of HCV patients will develop chronic infection. Approximately, HCV infects 170 million individuals worldwide). Chronic hepatitis C (CHC) patients are at high risk to develop lifethreatening complications, including cirrhosis in 20% of cases and hepatocellular carcinoma. Objectives The aim of this study was to validate Changes in serum level of autotaxin in patients with chronic hepatitis C before and after antiviral treatment. Patients and methods This study was designed as a prospective observational cohort study to evaluate Changes in serum levels of autotaxin with direct-acting antiviral therapy in patients with chronic hepatitis C before (baseline) and after (sustained virologic response week 12) treatment. This prospective study was conducted on 48 chronic HCV infected patients eligible for antiviral treatment with direct acting antivirals, agreeable to regular follow up, recruited from Hepatology and virology outpatient clinic at DMNI (Damanhour Medical National Institute) during the period from September 2018 till Mars 2019. Results This study showed that Autotaxin level significantly decreased from baseline to 12 weeks post-treatment. ATX therefore represents a novel non-invasive biomarker for liver fibrosis and a prognostic indicator of disease activity. Conclusion Serum Autotaxin was found to be higher in chronic hepatitis c and ATX levels became significantly decreased from baseline to 12 weeks post-treatment with direct acting antiviral drugs in patients achieving a SVR.
