BACKGROUND & AIMS: Oral direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment offer new hope to both pre- and post-liver transplant (LT) patients. However, whether to treat HCV patients pre- versus post-LT is not clear, as treatment can improve liver function but could reduce the chance of receiving a LT while on the waiting list. Our objective was to evaluate the cost-effectiveness of pre-LT versus post-LT HCV treatment with oral DAAs in decompensated cirrhotic patients on the LT waiting list...

Precision medicine is also possible for infectious diseases as shown for the treatment of chronic viral hepatitis, especially if different options are available. In hepatitis B virus (HBV) infection, treatment indication as well as the choice of treatment and the decisions to stop treatment are based on viral markers and alanine aminotransferase (ALT) level. Future therapies for HBV infection aiming for functional cure or even virus elimination may be even more personalized and have to take into account the immune status of a given patient...

BACKGROUND: Until recently, transplantation from hepatitis C positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen which has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature but little is known about the safety and efficacy of treatment in heart transplantation...

Deaths attributable to hepatitis C (HCV) infection are increasing in the USA even as highly effective treatments become available. Neighborhood-level inequalities create barriers to care and treatment for many vulnerable populations. We seek to characterize citywide trends in HCV mortality rates over time and identify and describe neighborhoods in New York City (NYC) with disproportionately high rates and associated factors. We used a multiple cause of death (MCOD) definition for HCV mortality. Cases identified between January 1, 2006, and December 31, 2014, were geocoded to NYC census tracts (CT)...

Discovery of sofosbuvir has radically changed hepatitis C treatment and nucleoside/tide NS5B inhibitors are now viewed as one of the key components in combination therapies with other direct-acting antiviral agents. As part of our program to identify new nucleoside inhibitors of HCV replication, we now wish to report on the discovery of β-d-2'-deoxy-2'-dichlorouridine nucleotide prodrugs as potent inhibitors of HCV replication. Although, cytidine analogues have long been recognized to be metabolized to both cytidine and uridine triphosphates through the action of cytidine deaminase, uridine analogues are generally believed to produce exclusively uridine triphosphate...

BACKGROUND AND AIMS: Hepatitis C Virus (HCV) infection is a common condition with endemic prevalence in some areas of the world. In Romania the mean prevalence is about 3%. New treatments became available on the market in recent years and new drugs are in the pipeline. A re-evaluation of HCV therapy was considered mandatory. The Romanian Society of Gastroenterology and Hepatology undertook this task for the practitioners of this country. METHODOLOGY: A group of recognized experts was created who screened the available literature and the major available guidelines...

Infection with hepatitis C virus (HCV) remains one of the serious human diseases worldwide, especially in Egypt, which can lead to cirrhosis or hepatocellular carcinoma (HCC). However, the exact molecular mechanism of HCC progress in HCV-infected patients remains unclear. Soluble fibrinogen-like protein 2 (sFGL2) is a modulator of the immune response that is secreted by T cells and inhibits maturation of dendritic cells and T cell proliferation. In the current study, serum sFGL2 levels were analyzed by enzyme-linked immunosorbent assay (ELISA) technique in 30 chronic HCV-infected patients (HCV group), 30 chronic HCV-infected patients with HCC (HCC group), and 12 healthy individuals (control group)...

At the 2017 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, Washington, hepatitis C virus (HCV) infection was a major focus in the context of HIV-associated liver disease. Well-tolerated direct-acting antiviral (DAA) regimens have enabled effective treatment of the populations that are hardest to cure, including those with decompensated cirrhosis, and many studies examined the impact of HCV cure on hepatitis and extrahepatic outcomes. Scaling up access to DAA, and the impact that their universal availability can have on reducing prevalence were key topics...

BACKGROUND AND AIMS: Direct antiviral agents (DAAs) have become the treatment of choice for patients with chronic hepatitis C virus (HCV) infection. As these drugs are new, it is important to learn the adverse events of these drugs in the short and long terms. We report on 7 patients who developed malignancies during treatment with DAAs or a short time after finishing treatment. METHODS: We treated 133 patients with DAAs in our unit between January 2015 and June 2016, 100 (75%) of whom were treated with the combination of paritaprevir/ritonavir/ombitasvir with/without dasabuvir (PrOD)...

BACKGROUND: Fatigue is a biological phenomenon that involves a feeling of extreme physical or mental tiredness that could potentially cause some severe chronic diseases. Recently, diet therapy has provided a new alternative to alleviate physical fatigue. In our previous study, addition of Cordyceps militaris (C. militaris) into an extruded product was shown to provide high nutrition and unique flavors; however, little is known whether this product has some scientific evidence regarding anti-fatigue property...

Liver cancer is highly fatal, and death rates in the United States are increasing faster than for any other cancer, having doubled since the mid-1980s. In 2017, it is estimated that the disease will account for about 41,000 new cancer cases and 29,000 cancer deaths in the United States. In this article, data from the Surveillance, Epidemiology, and End Results (SEER) Program and the National Center for Health Statistics are used to provide an overview of liver cancer incidence, mortality, and survival rates and trends, including data by race/ethnicity and state...

Tobacco smoke is a major risk factor for hepatic cancer. Epithelial-mesenchymal transition (EMT) induced by tobacco smoke is crucially involved in the initiation and development of cancer. Mitogen-activated protein kinase (MAPK) pathways play important roles in tobacco smoke-associated carcinogenesis including EMT process. The chemopreventive effect of curcumin supplementation against cancers has been reported. In this study, we investigated the effects of tobacco smoke on MAPK pathway activation and EMT alterations, and then the preventive effect of curcumin was examined in the liver of BALB/c mice...

BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs) are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). However, it is still questionable if eradication of hepatitis C virus in the blood eliminates hepatitis C in the body, and improves survival and leads to fewer complications...

Mono(2-ethylhexyl) phthalate (MEHP), the active metabolite of di(2-ethylhexyl) phthalate (DEHP), has been known to have adverse effects on the reproductive system, urologic systems, hepatic, developmental toxicities and carcinogenicity. However, the effect of MEHP on cardiovascular toxicity remains unclear. Therefore, we aimed to evaluate the cytotoxic effects of MEHP and the possible molecular mechanism. We found that treatment of EA.hy 926 cells with MEHP induced autophagy at earlier time (6 h) in this study...

OBJECTIVES: The objective of this study was to explore the trade-offs society and payers make when expanding treatment access to patients with chronic hepatitis C virus (HCV) infection in early stages of disease as well as to vulnerable, high-risk populations, such as people who inject drugs (PWID) and HIV-infected men who have sex with men (MSM-HIV). METHODS: A discrete time Markov model simulated HCV progression and treatment over 20 years. Population cohorts were defined by behaviors that influence the risk of HCV exposure: PWID, MSM-HIV, an overlap cohort of individuals who are both PWID and MSM-HIV, and all other adults...

Direct-acting antiviral agents (DAA) such as NS3 protease inhibitors is the first class of drugs used for chronic hepatitis C (CHC) treatment. NS3 inhibitors (PI) with low genetic barrier have been approved to be used in the CHC genotype 1 infections, and in the treatment of compensated liver disease including cirrhosis together with pegile interferon and ribavirin. Consequently, the development of drug resistance during DAA treatment of CHC is a major problem. NS3 resistant variants can be detected before treatment as they can occurnaturally...

Microorganism resistance is an important challenge in modern medicine due to the global uncontrolled use of antibiotics. Natural and synthetic antimicrobial peptides (AMPs) symbolize a new family of antibiotics, which have stimulated research and clinical interest as new therapeutic options for infections. They represent one of the most promising antimicrobial substances, due to their broad spectrum of biological activity, against bacteria, fungi, protozoa, viruses, yeast and even tumour cells. Besides, being antimicrobial, AMPs have been shown to bind and neutralize bacterial endotoxins, as well as possess immunomodulatory, anti-inflammatory, wound-healing, angiogenic and antitumour properties...
