Book Description
Hepatitis C virus (HCV), a major causative agent of chronic liver disease, is spread throughout the world and around 170 million people are persistently infected. In this volume, world-leading experts in the field of HCV research have compiled the most recent scientific advances to provide a comprehensive and very timely overview of the various facets of HCV. The book starts with a discussion of the possible origin of HCV and its spread among the human population. The focus of the subsequent chapters is on available cell culture and in vivo models before shifting to the molecular and cellular principles underlying the viral replication cycle. These chapters are complemented by insightful descriptions of the innate and adaptive immune responses to HCV as well as the virus-associated pathogenesis. Finally, the development of antiviral therapies, which is closely linked with progress in basic research, and the implementation of those therapies into present and future daily clinical practice are highlighted.

Book Description
Chronic viral hepatitis has emerged as one of the most common causes of disease and death worldwide. Because of their unique modes of replication and intimate association with the host immune system, hepatitis B virus (HBV) and hepatitis C virus (HCV) pose challenging problems to scientists in basic and applied research as well as to clinicians engaged in disease management. Although approved antiviral therapy is available for chronic HBV, the emergence of viral resistance provides a rationale for the development of novel chemotherapeutic agents. The lack of a robust cell culture system for HCV replication and a readily accessible small-animal model of HCV infection have hampered the development of antiviral agents for HCV. Neverthe-less, new antiviral agents targeting HCV are now in preclinical and clinical development. This monograph, providing an up-to-date overview of the field of Hepatitis Prevention and Treatment, includes contributions from internationally recognized experts in the field of viral hepatitis, and covers the current state of knowledge and practice regarding the molecular biology, immunology, biochemistry, pharmacology and clinical aspects of chronic HBV and HCV infection. The volume includes salient topics such as: the history and epidemiology of HBV and HCV; recent insights into the molecular mechanisms of viral replication; the host immune response to infection and a discussion of the use (HBV) or potential development (HCV) of vaccines; the current standard of care for chronically-infected patients; and emerging therapies and issues associated with current antiviral treatments. The latest information to researchers and clinicians actively engaged in viral hepatitis research is provided, but also sufficient background and discussion of the literature to benefit the newcomer to the field.

Book Description
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV) and infects approximately 75 million individuals worldwide. It is also one of the major causes of liver cancer and liver transplants. The elucidation of the HCV genome, and the development of a whole cell system to study the virus spurred the search for novel direct acting antiviral drugs to cure this disease. This global effort culminated in the development of direct acting antiviral drugs that led to cure rates approaching 100% in all patient populations after only 8-12 weeks of therapy. These efforts resulted in one of the greatest achievements in public health and provides the potential for eliminating HCV as a major disease worldwide. This volume is aimed at a broad audience of academic and industrial scientists interested in the discovery and development of drugs to treat viral diseases and those interested in reading about one of the most unique accomplishments in biomedical research. The volume will provide a one of a kind reference work that highlights the many efforts, from the discovery of the HCV virus, to the invention of breakthrough medicines and their use in the real world to cure patients. It is the companion book to the volume "HCV: The Journey from Discovery to a Cure - Volume II".

Book Description
Saliva Protection and Transmissible Diseases provides a review of saliva protection, raising debate on micro-organisms potentially transmissible in saliva, and also considering the evidence on diseases that may be transmitted by kissing. Saliva is a complex body fluid essential to health, especially mastication, swallowing and speech, and hyposalivation can lead to dysfunction and even infection. More serious pathogens, such as herpes viruses and papillomaviruses can be conveyed by kissing, as can potentially lethal micro-organisms present in some saliva, such as meningococci, fungal organisms and Ebola viruses. - Stipulates the defensive roles of saliva, an important topic not previously reviewed in-depth in literature - Provides awareness that saliva also transmits infectious agents that can produce serious or even lethal diseases - Gives understanding that kissing may be an at-risk practice

Book Description
The essential reference of clinical virology Virology is one of the most dynamic and rapidly changing fields of clinical medicine. For example, sequencing techniques from human specimens have identified numerous new members of several virus families, including new polyomaviruses, orthomyxoviruses, and bunyaviruses. Clinical Virology, Fourth Edition, has been extensively revised and updated to incorporate the latest developments and relevant research. Chapters written by internationally recognized experts cover novel viruses, pathogenesis, epidemiology, diagnosis, treatment, and prevention, organized into two major sections: Section 1 provides information regarding broad topics in virology, including immune responses, vaccinology, laboratory diagnosis, principles of antiviral therapy, and detailed considerations of important organ system manifestations and syndromes caused by viral infections. Section 2 provides overviews of specific etiologic agents and discusses their biology, epidemiology, pathogenesis of disease causation, clinical manifestations, laboratory diagnosis, and management. Clinical Virology provides the critical information scientists and health care professionals require about all aspects of this rapidly evolving field.

Book Description
Chronic Hepatitis C Virus: Lessons from the Past, Promise for the Future documents the monumental advances that have been made in our understanding of chronic HCV during the past decade. The first section reviews the natural history of chronic HCV, how this virus can affect other organs in addition to the liver, and whether treating chronic HCV alters the natural history of this disease. Section 2 reviews the advances that have been made in the treatment of chronic HCV during the past decade with interferon based therapy. Separate chapters on response guided therapy and how to manage the adverse events associated with these medications provide the physician with the concepts required to more effectively treat chronic HCV now and in the future. As the genetics of virologic response have recently been elucidated, a chapter is devoted to helping the clinician understand how genes that modulate disease processes and their treatment are identified and utilized in clinical care. Section 3 deals with the future of HCV treatment and specific inhibitors of HCV. Specific chapters explain how targets for drugs are identified and how drugs are then developed and tested; how mutations of HCV develop and how anti-viral agents will affect this process; the most up to date data regarding the treatment of chronic HCV with peginterferon, ribavirin and anti-viral agents; and the potential to treat chronic HCV with just oral anti-viral agents and without peginterferon and ribavirin in the future. The final section of this book covers issues related to liver transplantation in patients with chronic HCV. Separate chapters review the natural history of chronic HCV in liver transplant recipients and the impact of utilizing HCV positive donors. The volume concludes with chapters that cover the treatment of chronic HCV both prior to and after liver transplantation with potent anti-viral agents. Chronic Hepatitis C Virus: Lessons from the Past, Promise for the Future is a valuable resource for all physicians caring for patients with chronic HCV.

Book Description
The first observation of cold-induced precipitation of serum proteins dates back to 1933, when Wintrobe and Buell first described an unusual case of multiple myeloma in a woman whose serum reversibly precipitated at cold temperatures. In 1947 Lerner and Watson showed cold-precipitable proteins to be gammaglobulins and called them ‘cryoglobulins’ and the corresponding clinical condition ‘cryoglobulinemia’. Meltzer and Franklin in 1966 provided an accurate description of the typical clinical symptoms associated with cryoglobulinemia, showed that they consisted of two different globulin components and, because of the ignorance on its etiology, called this clinical condition ‘essential mixed cryoglobulinemia’. For almost 20 years progress has been rather slow in this field, but when at the end of the ‘80s it finally became possible to detect the occurrence in the serum of antibodies to the hepatitis C virus (HCV), many groups in Europe and the United States almost simultaneously reported that a high proportion of ‘essential’ cryoglobulinemias are in fact associated with HCV infection. This hallmark has resulted in a new impetus and great enthusiasm in carrying out new researches made possible by the awareness that cryoglobulinemia is to be considered an undisputable extrahepatic manifestation of HCV infection. In addition, the evidence that HCV has tropism for hepatocytes and lymphocytes has stimulated new approaches to the autoimmune phenomena and the potential transformation in non-Hodgkin’s lymphomas which not infrequently can be discovered in these patients. The same applies to the obvious therapeutic implications, once the association between HCV infection and mixed cryoglobulinemia has been firmly established. It was thus felt that times were ripe to produce a state-of-the-art survey of the multi-faceted picture of cryoglobulinemia. This book is indeed unique in the detail of its presentation, its completeness and its fundamental approach to the subject. The most qualified authors have been invited to contribute critical articles reviewing significant developments related to each of the eight sections in which the whole treatment has been divided: from basic mechanisms governing interactions between HCV and the immune system to the immunochemical characterization of cryoglobulins and the frequently concomitant serological abnormalities; from genetic features and the role of certain cytokines and chemokines to the cellular compartments of HCV infection and replication; from the clinical manifestations of cryoglobulinemic patients and their potential susceptibility to develop non-Hodgkin’s lymphoma to conventional treatment of the syndrome and the newer, promising therapeutic advances. The reader will appreciate the immediacy of style, the striking illustrations, and the color plates. In addition, the comprehensive review of a systemic disease such as cryoglobulinemia will interest basic scientists and specialists involved in several disciplines, including internal medicine, hepatology, hematology, oncology, infectious diseases, rheumatology, nephrology and dermatology. General practitioners, graduate and post-graduate students will also find in this book an irreplaceable source of update in this fascinating field.

Book Description
Hepatitis B and C cause most cases of hepatitis in the United States and the world. The two diseases account for about a million deaths a year and 78 percent of world's hepatocellular carcinoma and more than half of all fatal cirrhosis. In 2013 viral hepatitis, of which hepatitis B virus (HBV) and hepatitis C virus (HCV) are the most common types, surpassed HIV and AIDS to become the seventh leading cause of death worldwide. The world now has the tools to prevent hepatitis B and cure hepatitis C. Perfect vaccination could eradicate HBV, but it would take two generations at least. In the meantime, there is no cure for the millions of people already infected. Conversely, there is no vaccine for HCV, but new direct-acting antivirals can cure 95 percent of chronic infections, though these drugs are unlikely to reach all chronically-infected people anytime soon. This report, the second of two, builds off the conclusions of the first report and outlines a strategy for hepatitis reduction over time and specific actions to achieve them.
