Hepatitis C combination therapy and the effects of alcohol

Tingting Ren, Juanjuan Zhu, Lili Zhu, Mingliang Cheng
Nonalcoholic steatohepatitis (NASH) is liver inflammation and a major threat to public health. Several pharmaceutical agents have been used for NASH therapy but their high-rate side effects limit the use. Blueberry juice and probiotics (BP) have anti-inflammation and antibacterial properties, and may be potential candidates for NASH therapy. To understand the molecular mechanism, Sprague Dawley rats were used to create NASH models and received different treatments. Liver tissues were examined using HE (hematoxylin and eosin) and ORO (Oil Red O) stain, and serum biochemical indices were measured...

Chronic hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. In the last 5 years, treatment for HCV infection has experienced a marked development. In 2014, the use of ledipasvir/sofosbuvir with or without concomitant weight-based ribavirin was approved with a very significant increase in the sustained virological response. However, new side effects have been associated. We report the first case of an HCV infected patient treated for 12 wk with the combination of sofosbuvir/ledipasvir plus ribavirin who developed a miliary tuberculosis (TB) infection while on therapy...

BACKGROUND: Liver fibrosis and its sequel cirrhosis represent a major health care burden, and assessment of fibrosis by biopsy is gradually being replaced by noninvasive methods. In clinical practice, the determination of fibrosis stage is important, since patients with advanced fibrosis have faster progression to cirrhosis and antiviral therapy is indicated in these patients. AIMS: To assess the role of transient elastography (TE) and compare it with APRI and FIB4 for predicting liver fibrosis and assessing the effect of host and viral factors on fibrosis and treatment outcome in CHC patients...

BACKGROUND AND 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...

BACKGROUND: Isolated hepatitis B core antibody (anti-HBc) is a common serologic finding in HIV-infected persons, but the clinical significance is uncertain. We studied HIV/hepatitis C virus (HCV)-infected women over time to determine whether the trajectory of liver disease progression is affected by isolated anti-HBc serologic status. METHODS: We performed serial enhanced liver fibrosis (ELF) markers on HIV/HCV-coinfected women to assess liver disease progression trajectory over time comparing women with isolated anti-HBc to women with either negative HB serologies, anti-HBs alone, or anti-HBc and anti-HBs...

Alcohol consumption and hepatitis C virus (HCV) infection have a synergic hepatotoxic effect, and the coexistence of these factors increases the risk of advanced liver disease. The main mechanisms of this effect are increased viral replication and altered immune response, although genetic predisposition may also play an important role. Traditionally, HCV prevalence has been considered to be higher (up to 50%) in alcoholic patients than in the general population. However, the presence of advanced alcoholic liver disease (ALD) or intravenous drug use (IDU) may have confounded the results of previous studies, and the real prevalence of HCV infection in alcoholic patients without ALD or prior IDU has been shown to be lower...

Sorafenib has been a standard therapy for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. Hepatic arterial infusion chemotherapy (HAIC) is still preferably performed in Japan because of its relatively good tumor-shrinking effect. We report a case of advanced multiple HCC with portal thrombus that responded to combination chemotherapy with sorafenib and repeat hepatic arterial infusion with a fine-powder formulation of cisplatin (IA-call®). A 57-year-old man presented for the treatment of HCC with alcoholic cirrhosis...

OBJECTIVES: HIV-related renal diseases are the leading causes of chronic kidney diseases worldwide. The present study aimed to investigate the prevalence of pathological proteinuria and its risk factors among HIV patients. METHODS: A review of the medical records of 666 HIV-infected individuals aged 18 years or older in an urban HIV/AIDS clinic based in Porto Alegre in southern Brazil. Overt proteinuria was defined as a protein-to-creatinine ratio greater than 150 mg/g according to Kidney Disease: Improving Global Outcomes...

BACKGROUND AND AIMS: In many countries, current treatment for patients with chronic hepatitis C involves a combination of peginterferon and ribavirin, associated with a protease inhibitor for hepatitis C virus genotype 1. More recent and efficient less toxic antiviral treatments are now available for some patients. Thus, the decision to treat or to wait is challenging. The aims of this study were to: (a) estimate the proportion of treated patients, (b) evaluate the reasons for this decision, and (c) examine the patients' points-of-view in treatment decision...

Visceral and hepatic adiposities have been associated with both cardiovascular and liver disease and are of concern in HIV-infected persons in the modern era of combination antiretroviral therapy (ART). The development of therapeutic targets to reduce visceral and hepatic adiposities in HIV-infected persons has been slow, because of early reports that attributed the excess adiposity to specific antiretroviral drugs. Visceral adiposity was initially thought to occur as part of a protease inhibitor-induced "HIV-associated lipodystrophy syndrome...

Hepatocellular carcinoma is the major complication of chronic liver diseases and particularly of cirrhosis whatever its etiology. Once encountered mainly in the endemic countries of hepatitis B and C, the incidence of hepatocellular carcinoma (6/100,000) is parallel to the global development of diabetes, overweight and alcohol consumption. Little progress has been made for this cancer, whose mortality is 100 % at 10 years. Liver transplantation is the only truly curative treatment (survival more than 50 % at 10 years) since it allows the eradication of hepatocellular carcinoma and its essential cause, cirrhotic liver...

Chronic hepatitis C virus infection is usually asymptomatic. The severity of the hepatic lesion in these patients at diagnosis varies and, from the histopathologic point of view, most have mild disease. A series of factors have been described that correlate with the progression of fibrosis in patients with mild fibrosis: age at diagnosis, the duration of the infection, male sex, HIV coinfection, transaminase levels during follow-up, alcohol consumption, metabolic factors such as diabetes and overweight, necroinflammatory activity in the initial biopsy, and the degree of steatosis...

BACKGROUND: Published clinical trials of the treatment of HCV are largely multicentre prospective pharmaceutical trials. Patients in clinical trials tend to have more favorable outcomes than patients in the 'real-world', due to strict patient selection and differences in treatment conditions and available resources. OBJECTIVES: To assess the outcomes of Hepatitis C infected patients treated at the Barwon Health Liver Clinic with combination Pegylated interferon (PEG-IFN) and Ribavirin (RBV) therapy and to determine factors associated with a treatment response...

The late and fast developments in the field of viral hepatitis were highly expected in the 2014 AASLD Liver Meeting®. Several combinations using direct acting antivirals (DAAs) showed high rates of sustained virological response (∼95%). Importantly, high cure rates were also demonstrated in patients with previous treatment failures, decompensated cirrhosis and hepatitis C recurrence after transplantation, making it clear that the interferon era is over (not so clear for ribavirin, which might still have a role in difficult-to-treat populations)...

BACKGROUND: Patients with bipolar disorder are exceptionally challenging to manage because of the dynamic, chronic, and fluctuating nature of their disease. Typically, the symptoms of bipolar disorder first appear in adolescence or early adulthood, and are repeated over the patient's lifetime, expressed as unpredictable recurrences of hypomanic/manic or depressive episodes. The lifetime prevalence of bipolar disorder in adults is reported to be approximately 4%, and its management was estimated to cost the US healthcare system in 2009 $150 billion in combined direct and indirect costs...

INTRODUCTION: Several factors such as duration of infection, age, male gender, consumption of alcohol, HIV infection and low CD4 count have been associated with fibrosis progression rate. However, it is relatively scarce, the knowledge about the liver fibrosis progression rate in HIV-infected patients with undetectable HIV viral load (VL). For this reason, we performed the present study. MATERIALS AND METHODS: Observational and multicenter study (2008-2012) conducted in four hospitals of the northern Spain...

OBJECTIVES: Although effective HCV treatment is available, it can be difficult to access for uninsured, urban patients. Our aim was to assess the utility of evaluation and outcomes in the uninsured with HCV when access to health care and treatment with triple therapy is provided. METHODS: We performed a retrospective review of consecutive patients referred for HCV from 2011 to June 2013 to an indigent HCV clinic. The primary outcomes were assessment of disease severity by noninvasive means and initiation of therapy...

The advance of antiviral treatment for chronic hepatitis C has brought a high sustained virological response (SVR) rate. In this review article, the suppressive effect of interferon (IFN)-based therapy on the development of hepatocellular carcinoma (HCC), risk factors for developing HCC and the characteristics of HCC development after SVR among chronic hepatitis C patients given IFN-based therapy were studied. The HCC incidence has been revealed to decrease with IFN-based antiviral therapy, especially in SVR, and the risk factors for developing HCC were older age, advanced liver fibrosis and male sex...

BACKGROUND & AIMS: Direct-acting antivirals that target nonstructural protein 5A (NS5A), such as daclatasvir, have high potency against the hepatitis C virus (HCV). They are promising clinical candidates, yet little is known about their antiviral mechanisms. We investigated the mechanisms of daclatasvir derivatives. METHODS: We used a combination of biochemical assays, in silico docking models, and high-resolution imaging to investigate inhibitor-induced changes in properties of NS5A, including its interaction with phosphatidylinositol-4 kinase IIIα and induction of the membranous web, which is the site of HCV replication...

OBJECTIVES: Antiretroviral interruption is associated with liver fibrosis progression in HIV/hepatitis C virus (HCV) coinfection. It is not known what level of HIV viraemia affects fibrosis progression. METHODS: We evaluated 288 HIV/HCV-coinfected cohort participants with undetectable HIV RNA (<50 HIV-1 RNA copies/mL) on two consecutive visits while on combination antiretroviral therapy (cART) without fibrosis [aspartate aminotransferase to platelet ratio index (APRI) <1...
