BACKGROUND: There are no approved treatments for liver fibrosis. To aid development of anti-fibrotic therapies, non-invasive biomarkers that can identify patients with progressive fibrosis and that permit monitoring of the response to anti-fibrotic therapy are much needed. METHODS: Samples from a phase II anti-fibrotic trial of the glitazone farglitazar in patients with advanced hepatitis C, with matched follow-up liver biopsies, and from a phase III study of balaglitazone in late stage type 2 diabetics (BALLET study), were analysed for serological Pro-C3 levels in conjunction with other disease parameters...

Trans persons, including transvestites and transsexual women, show disproportionately high HIV/AIDS rates when compared to the rest of the population. However, few quantitative/qualitative studies have addressed trans persons in Brazil. Thus, a team of researchers from different fields is developing an interdisciplinary research project with the objective of shedding light on living conditions and ways of life among transvestites and transsexual women, while investigating determinant factors for HIV infection, syphilis, and hepatitis B and C...

PURPOSE OF REVIEW: Hepatocellular carcinoma (HCC) is becoming an important cause of mortality in patients with HIV, attributed to coinfection with hepatitis C virus, hepatitis B virus, and the longer survival advantage these patients are achieving after introducing the highly active antiretroviral therapy (HAART) regimens. RECENT FINDINGS: In addition to hepatitis infection, immunosuppression secondary to HIV infection, direct impact of the virus on liver parenchyma, and the use of hepatotoxic antiretroviral drugs, all contribute to HCC pathogenesis...

Hepatitis caused by hepatitis B and C virus is increasingly becoming a significant global health threat, with widespread prevalence that may have severe disease and economic impacts in the future. Yet, preventative measures are not implemented universally and high costs of medicines limits treatment efforts. The global response to HIV/AIDS faced similar issues, but overcame them through a global movement that brought attention to the crisis and ultimately resulted in the creation and implementation of and access to better tools for HIV prevention and treatment...

BACKGROUND: Antiviral therapy improves hepatic outcomes in hepatitis C virus (HCV)-infected cancer patients. However, such patients are not treated simultaneously with antivirals and chemotherapy, owing to overlapping toxicities with previous standard of care treatment of pegylated interferon and ribavirin. AIM: To examine the safety and clinically-significant drug-drug interactions observed in patients who received simultaneous treatment with direct-acting antivirals (DAAs) and chemotherapy...

The in vitro predictive evaluation of chemical carcinogenicity based on hepatic premalignance has so far not been established. Here, we report a novel approach to investigate the premalignant events triggered by human carcinogen aristolochic acid I (AAI) in the liver-like tissue derived from mouse embryonic stem cells. By AAI exposure, the liver-like tissue exhibited the paracrine interleukin-6 phenotypic characteristics. Hepatocytes expressed STAT3/p-STAT3, c-Myc and Lin28B in parallel. Some of them displayed the dedifferentiation characteristics, such as full of α-fetoprotein granules, increase in size, and nucleocytoplasmic shuttle of Oct4...

The HIV/AIDS epidemic, which was first reported on in 1981, progressed in just 10 years to a disease afflicting 10 million people worldwide including 1 million in the US. In 1987, AZT was approved for treating HIV/AIDS. Unfortunately, its clinical usefullness was severly limited by associated toxicities and the emergence of resistance. Three other drugs that were approved in the early 1990s suffered from similar liabilities. In 1990, the Liotta group at Emory University developed a highly diastereoselective synthesis of racemic 3'-thia-2',3'-dideoxycytidine and 3'-thia-2',3'-5-fluorodideoxycytidine and demonstrated that these compounds exhibited excellent anti-HIV activity with no apparent cytotoxicity...

Lyme disease caused by the spirochete Borrelia burgdorferi has become a major worldwide epidemic. Recent studies based on Big Data registries show that >300,000 people are diagnosed with Lyme disease each year in the USA, and up to two-thirds of individuals infected with B. burgdorferi will fail conventional 30-year-old antibiotic therapy for Lyme disease. In addition, animal and human evidence suggests that sexual transmission of the Lyme spirochete may occur. Improved companion diagnostic tests for Lyme disease need to be implemented, and novel treatment approaches are urgently needed to combat the epidemic...

OBJECTIVES: The existence of street and working children in Iran is undeniable. The precarious conditions of these children (including disrupted family, poverty, high prevalence of crime among relatives, family members and peers) cause social harm and high-risk behaviours, including drug addiction, selling sex or having sex with adolescents or peers. Here we explore the HIV, hepatitis B and hepatitis C status of street and working children in Tehran. METHODS: One thousand street and labour children, aged 10-18 years, were recruited by using the time-location sampling method, and semistructured questionnaires were used to find demographic information and information on HIV/AIDS-related high-risk sexual behaviours...

We reviewed the first 21 years (1991-2011) of Australia's National Notifiable Diseases Surveillance System (NNDSS). All nationally notified diseases (except HIV/AIDS and Creutzfeldt-Jakob disease) were analysed by disease group (n = 8), jurisdiction (six states and two territories), Indigenous status, age group and notification year. In total, 2 421 134 cases were analysed. The 10 diseases with highest notification incidence (chlamydial infection, campylobacteriosis, varicella zoster, hepatitis C, influenza, pertussis, salmonellosis, hepatitis B, gonococcal infection, and Ross River virus infection) comprised 88% of all notifications...

Many viruses encode or subvert cellular microRNAs (miRNAs) to aid in their gene expression, amplification strategies, or pathogenic signatures. miRNAs typically downregulate gene expression by binding to the 3' untranslated region of their mRNA targets. As a result, target mRNAs are translationally repressed and subsequently deadenylated and degraded. Curiously, hepatitis C virus (HCV), a member of the Flaviviridae family, recruits two molecules of liver-specific microRNA-122 (miR-122) to the 5' end of its genome...

Tripartite motif 14 (TRIM14) was reported to function as a mitochondrial signaling adaptor in mediating innate immune responses. However, the involvement of TRIM14 in host defense against viral infection and molecular mechanisms remain unclear. Here, we demonstrated that enforced expression of TRIM14 could potently inhibit the infection and replication of HCV in hepatocytes, whereas TRIM14 knockout cells became more susceptible to HCV infection. Interestingly, further experiments revealed that such anti-HCV activity was independent of activating the NF-κB or interferon pathways but required the C-terminal SPRY domain of no signaling capacity...

Hepatitis C virus (HCV) represents a major global health threat. The envelope glycoproteins, E1-E2 of HCV play an important role in infection by binding to hepatocyte surface receptors leading to viral entry. Several regions on the E1-E2 are conserved for maintaining structural stability, despite the high mutation rate of HCV. Identification of antigenic determinants in these domains would aid in the development of anti-virals. The present study was aimed to delineate neutralizing epitopes by generating monoclonal antibodies (mAbs) to envelope proteins that can block virus binding and entry...
