Book Description :

Chronic viral hepatitis remains one of the major medical problems worldwide. Neither a cure nor eradication of this disease is in sight. The chronic disease caused by hepatitis viruses type B, C and D is a much greater problem than the acute disease caused by the same viruses or by hepatitis viruses type A and E. Chronic viral hepatitis often remains unrecognized until the patient develops decompensated liver cirrhosis or hepatocellular carcinoma. Furthermore, unrecognized chronic virus carriers are a persistent source of infection by sexual and other close contacts as well as during many medical procedures. The viruses of chronic hepatitis are very different from each other from a taxonomical point of view, but they share many common pathogenic properties and they often coinfect individuals. Six years ago Carlo De Bac, Gloria Taliani (Rome) and I undertook an effort to bring together, under the auspices of the European Society against Virus Diseases, clinicians, laboratory physicians, epidemiologists, pathologists and molecular biologists whose primary research interest is chronic viral hepatitis. The contributions from these quite divergent participants to a meeting devoted solely to chronic viral hepatitis were most stimulating and valuable. As a result of the success of the first meeting in Fiuggi (Italy), a second followed in Siena (Italy) 1990 and the recent third meeting was held in Pisa (Italy). Most of the speakers expressed interest in publishing their contributions in the form of a proceedings volume, as was done in the case of the Siena meeting.

Book Description :

Hepatitis viruses research started more than fifty years ago. The names of hepatitis A and hepatitis B were introduced in 1947 when it became clear that there were two types of hepatitis that were transmitted either enterically or parenterally. It became apparent in the 1970's that there were additional hepatitis viruses distinct from hepatitis A and hepatitis B, and thus, the term non-A, non-B hepatitis was introduced. The non-A, non-B hepatitis was further divided into post-transfusion non-A, non-B hepatitis and enterically-transmitted non-A, non-B hepatitis in the 1980's. By the end of the 1980's, both post-transfusion non-A, non-B virus and enterically-transmitted non-A, non-B virus had been identified and renamed hepatitis C virus and hepatitis E virus, respectively. Hepatitis delta antigen was first recognized as an antigen associated with hepatitis B virus infection in the 1970's. In the early 1980's, a virus was isolated and named hepatitis delta virus. These five different hepatitis viruses have distinct replication pathways and are major health concerns. They have become an important topic for teaching to graduate-level and medical students. Hepatitis Viruses provides a comprehensive, up-to-date review of these viruses to readers. Each chapter is written by one of the top researchers in the field, and topics include: the epidemiology and the natural history of infection of these viruses, the molecular biology and the replication cycle of individual hepatitis viruses, host-virus interactions and the pathogenesis of hepatitis viruses, the immunology of hepatitis viruses, the relationship between hepatitis viruses and hepatocellular carcinoma, the viral vaccines and antiviral drugs. This book can serve as a supplemental reading material to graduate students and medical students, and to any researcher who would like to learn more about hepatitis viruses.

Book Description :

Both hepatitis C virus (HCV) and hepatitis B virus (HBV) infections represent major global public health problems. Interferon (IFN) has been an important factor in both resolution of infection and in the treatment of both infections. Clinical data on anti-HBV and anti-HCV innate immune responses, in particular the IFN response, during natural infection in patients are limited. This is, in part, because most of patients are asymptomatic during acute stages of infection. IFN has been used to treat both HBV and HCV infections for years. Unfortunately, many patients do not respond to the IFN therapy. The reason for the variable treatment outcomes, in particular, the nonresponsiveness to IFN therapy in both HBV and HCV infections still remains unclear. In this thesis, IFN responses in HBV and HCV infections were studied using the severe combined immunodeficiency (SCID) / beige (bg) - albumin (Alb) / urokinase-type plasminogen activator (uPA) chimeric mouse model. The SCID/bg-Alb/uPA chimeric mouse model was initially reported in 2001. This model supports robust and sustained infection by clinical or tissue culture derived hepatitis viruses, such as hepatitis A virus (HAV), HBV and HCV. Evidence has shown that the antiviral response to IFN in the chimeric mouse often reflects closely the response of the identical virus in humans when treated with IFN. A time course of HCV infection was performed in SCID/bg-Alb/uPA chimeric mice to study an induced endogenous IFN response. There was a peak of interferon-stimulated gene (ISG) response at day-10 post infection, but no significant ISG upregulation was observed in long-term HCV infection in the mice. I also investigated the contributions of viral and host factors on the response of HCV infection to IFN treatment using two HCV viral strains differing in their IFN-sensitivity. These studies were performed in chimeric mice produced using three hepatocyte donors, each with distinct interleukin (IL) 28B single nucleotide polymorphisms (SNPs) at both rs12979860 and rs8099917 loci. My results showed that virus factors were the key factors determining the outcome of IFN therapy, whereas, viral interference with host janus kinase - signal transducer and activator of transcription (JAK-STAT) pathway as well as host factors, such as polymorphisms at the IL28B loci and pre-treatment levels of intrahepatic ISG expression, were less important in determining the outcome of IFN therapy in chimeric mice than they are in the patients. In addition, endogenous IFN response during the course of HBV in the SCID/bg- Alb/uPA chimeric mice was examined. No significant IFN or ISG response was detected in chimeric mice during the course of HBV infection. Since both the HBV and HCV viruses used in my studies were nonresponsive to exogenous IFN treatment in chimeric mice, the molecular mechanism of IFN nonresponsiveness of the two viruses was compared in a cohort of donor-matched chimeric mice. I found that in HBV infected chimeric mice, but not in mice infected with HCV, the JAK-STAT pathway was inhibited by STAT1 nucleus translocation blockage and thus expression downregulation of ISGs in response to exogenous IFN treatment. Finally, two collaborative projects were completed during my PhD. In the first study, the potential antiviral activity of exogenous HCV pathogen-associated molecular pattern (PAMP) RNA was investigated in HCV-infected SCID/bg- Alb/uPA chimeric mice. My results suggested that HCV PAMP RNA administration elicited an innate immune response in the livers of chimeric mice, which limited HCV infection. In the second study, we found that HCV infection in chimeric mice enhanced microRNA-27 expression and resulted in upregulating hepatic lipid droplet (LD) biogenesis. These results represented a novel mechanism by which HCV induces steatosis in chronic carriers of HCV.

Book Description :

A series of international symposia on viral hepatitis and liver disease has been held triannially, and called the "Olympics" of this research field. Our book presents the results of the eighth of these "Olympiads" which for the first time, was held in Asia (May 1993, Tokyo). Due to the rapid progress in research on both basic and clinical aspects of viral hepatitis and liver disease, the state of the art in this field is continually being updated, and our book provides a broad and in-depth survey of current work. The major topics in our book include molecular biology of the five known hepatitis viruses (HAV, HBV, HCV, HDV, and HEV), clinical implications of genetic variants of HBV and HCV, interferon treatment of HCV-related liver disease, and worldwide epidemiology and control of viral hepatitis. New subjects not seen in previous books, such as genotypes of HCV, are also covered. Expanding knowledge about the heterogeneity of the HCV genome has revealed a great variety of genotypes as well as their association with host pathogenesis and their varying responsiveness to interferon therapy. The first promising results of efforts to develop a hepatitis C vaccine are also presented. Finally, compared with its predecessors, our book contains many more papers from Asian countries, where the prevalence of viral hepatitis and liver disease is the highest in the world.

Book Description :

Despite the availability of an effective vaccine, there are still 400 million people, worldwide who are chronically infected with hepatitis B virus (HBV). For them, the vaccine, as currently applied, has no value. Given the possible consequences of HBV infection, the number of those chronically infected with HBV presents an enormous public health challenge. For example, the major etiology of hepatocellular carcinoma (HCC) is chronic infection with HBV. Although fifth in cancer incidence, worldwide, HCC/liver cancer is the third leading cause of cancer death. The high mortality as- ciated with HCC arises because the disease is often detected late and is unresponsive to treatment. The number of deaths caused by PHCC is expected to rise over the next 20 years. Those chronically infected with HBV have a life risk of death to HCC of between 10 and 25%. Even the limited efficacy of drugs for the treatment of chronic HBV helps underscore the point that this disease is responsive to therapy. Drugs that target the polymerase (e. g. , hepsera and lamivudine) and interferon alpha represent two distinct strategies and show that both conventional antiviral and immunothe- peutic approaches can be used in management. However, the current inventory of therapeutics is inadequate. Interferon alpha is of limited value, only parenterally ava- able, and fraught with adverse reactions.

Book Description :

This important book comprises a narrative account of research on the hepatitis B virus (and related subjects) and selected reprints from the laboratory of Nobel laureate Baruch S Blumberg and his colleagues. The hepatitis B virus (HBV) is one of the ten most common deadly infectious diseases and is responsible for 1.1 million deaths a year worldwide. Research in his laboratory resulted in the discovery of HBV and the invention of the vaccine which protects one against it. The research began as an apparently esoteric study of human biochemical and immunologic variation. This required field-work in Africa, the Arctic, the Pacific, the Americas, and in many other locations and populations. The overall goal was to identify inherited biological differences which were related to differing responses to disease-causing agents. The virus was discovered using the blood of an infected person who had developed the antibody, to detect the virus present in another infected person who had become a carrier of the virus. Screening of blood donors led to the near-elimination of post-transfusion hepatitis B. There are now national HBV vaccination programs in more than 70 countries. During the past decade these programs have strikingly reduced the prevalence of HBV in many countries and there has been a significant drop in the incidence of cancer of the liver in the vaccinated cohorts. The HBV vaccination program is now, after smoking cessation, the most widely used cancer prevention program in the world.

Part I. Hepatitis B virus (HBV) infection is a serious public health problem with more than 2 billion people infected worldwide. The reverse transcriptases of the viruses in the HBV family share a highly conserved domain structure and play key roles in viral replication. Thus, the HBV reverse transcriptase (RT) is an ideal target for developing effective anti-HBV agents to prevent the development of HBV-induced liver disease.
