INTRODUCTION: Presence of anti-E1E2 antibodies was previously associated with spontaneous cure of hepatitis C virus (HCV) and predictive before treatment of a sustained virological response (SVR) to bi- or tri-therapy in naïve or experienced patients, regardless of HCV genotype. We investigated the impact of anti-E1E2 seroprevalence at baseline on treatment response in patients receiving direct-acting antiviral (DAA) therapy. MATERIAL AND METHODS: We screened anti-E1E2 antibodies by ELISA in serum samples collected at treatment initiation for two groups of patients: 59 with SVR at the end of DAA treatment and 44 relapsers after DAA treatment...

New directly acting antivirals (DAAs) provide very high cure rates in most patients infected by hepatitis C virus (HCV). However, some patient groups have been relatively harder to treat including those with cirrhosis or infected with HCV genotype 3. In the recent BOSON trial, genotype 3, cirrhotic patients receiving a 16 week course of sofosbuvir and ribavirin had a sustained virologic response rate (SVR) of around 50%. In cirrhotic patients, IFNL4 CC genotype was significantly associated with SVR. This genotype was also associated with a lower interferon-stimulated gene (ISG) signature in peripheral blood and in liver at baseline...

BACKGROUND: Hepatocellular carcinoma (HCC) develops in some patients who achieve sustained virological response (SVR) against hepatitis C virus (HCV) infection via anti-HCV therapy. To examine the pathogenesis of HCC development after HCV eradication, histopathological changes and clinical markers were evaluated in SVR patients. METHODS: Of 654 SVR patients treated with interferon (IFN)-based therapies, 34 patients who had undergone liver biopsy before initiating IFN therapy and after SVR achievement were enrolled: 11 patients with HCC and 23 patients without HCC (male/female, 9/2 and 8/15, respectively: age, 58 ± 5 and 54 ± 11 years, respectively)...

IL-22 plays a vital role in improving hepatic damage by targeting hepatocytes that express high levels of IL-22 receptor1. IP-10 is a chemokine that recruit mononuclear cells to liver parenchyma and improves the host immune response against hepatitis C virus. The study targeted 27 patients with chronic HCV who received pegylated Interferon and Ribavirin. IL-22 and IP-10 serum levels were measured by Elisa. The level of the serum IL-22 is higher in HCV patients groups receiving the antiviral treatment compared to control group and its levels significantly increased with response to treatment...

Pegylated interferon-alpha (pIFN-α) is suggested to lower HIV-1 DNA load in antiretroviral therapy (ART) treated patients. We studied the kinetics of total HIV-1 DNA levels in 40 HIV-1/hepatitis C (HCV) coinfected patients, treated with pIFN-α for HCV and categorized into three groups according to start of ART: Chronic HIV-1 infection (n=22), acute HIV-1 infection (n=8), no-ART (n=10). Total HIV-1 DNA levels were quantified in 247 PBMC samples and remained stable before, during, and after pIFN-α treatment in all three groups...

Hepatitis C virus (HCV) infection is a major cause of chronic liver disease. HCV cure has been linked to improved patient outcomes. In the era of direct-acting antivirals (DAAs), HCV cure has become the goal, as defined by sustained virological response 12 weeks (SVR12) after completion of therapy. Historically, African-Americans have had lower SVR12 rates compared to White people in the interferon era, which had been attributed to the high prevalence of non-CC interleukin 28B (IL28B) type. Less is known about the association between race/ethnicity and SVR12 in DAA-treated era...

Hepatitis C virus (HCV) infection is widely diffused in general population, and the likelihood that an infected individual is affected by other disesases is high. A lot of epidemiological and explicative studies, even if with different levels of evidence, reported a potential effect of HCV infection -by direct and indirect mechanisms- on the pathogenesis of extrahepatic comorbidities related to dysregulation of the immune system, or cardiometabolic comorbidities like diabetes, neuropsychiatric disorders, chronic kidney disease, cardiovascular alterations, etc...

AIM: Alcohol could compromise the anti-hepatitis C virus (HCV) function of interferon-alpha (IFN-α). However, little information is available about the effect of alcohol on interferon-lambda (IFN-λ, type III IFN), a novel candidate for development of therapy for HCV infection. METHODS: Huh7 cells were infected with HCV JFH-1 virus, then treated with alcohol and/or IFN-λ1. RT-PCR and western blot were used to detect the levels of HCV and key cellular factors. Overexpression or silencing expression was performed to verify the role of key factors in alcohol-attenuated anti-HCV function of IFN-λ1...
