Helicobacter Pylori Research

This book provides the current updated knowledge on all essential aspects in the rapidly evolving area of Helicobacter pylori research. H. pylori is a class I carcinogen and one of the most common infections in the world. While most people colonized by H. pylori will remain asymptomatic, up to 20 % of them may develop serious gastroduodenal disease such as peptic ulcers or gastric cancer. H. pylori is the only known bacterium linked to the development of cancer and consequently is an important focus of research. Outstanding international experts from diverse scientific disciplines contribute here to give detailed insights into the current understanding concerning the physiology and role of this pathogen. Both basic science and clinical research with actual practical consequences are taken into account. The chapters target microbiology, epidemiology, genetics, biochemistry, interactions with the immune system, signal transduction, pathogenic mechanisms in the gastroduodenal mucosa, gastric disease development, and therapy including antibiotics or probiotics treatment as well as vaccination strategies. This book is an important reference not only for clinicians but also microbiologists. It provides in a single volume an up-to-date summary of our current knowledge of this microbe and the multiple ways in which it impacts upon public health in all parts of the world.

The impact of Helicobacter pylori on basic science and the clinical management of patients with the complications of this infection is bewildering. The explosion of new information both in the laboratory and at the bedside has progressed at an unprecedented rate. Our main objective in furthering this progress has been to integrate this new information and organize a series of top-quality presentations and discussions between investigators and clinicians on all aspects of H. pylori research and to review the current position and future research directions. To that end, the second meeting 'Helicobacter pylori: Basic Mechanisms to Clinical Cure' was organized in June 1996 in Ottawa, Canada, following the successful format of the first such meeting held in Amelia Island, Florida, in 1993. The meeting again focused on all timely aspects of H. pylori research. Internationally renowned basic and clinical scientists, all experts in their respective fields, explored in depth the spectrum of H. pylori infection and the related complications of gastritis, peptic ulcer, gastric cancer and lymphoma.

This volume explores in detail the molecular biology, genetics and immunology of the bacterium Helicobacter pylori that causes serious gastric diseases such as gastric cancer. The book provides in-depth insights into the mechanisms of H. pylori-induced pathogenicity, gives an overview of how the bacterium colonizes the human gut, how it manages to persist in the body and which factors play a role in the development of H. pylori-induced gastric cancer. Furthermore, the interaction between the Gram-negative bacterium and the human gut microbiome is explored, and clinical management and treatment strategies to combat gastric cancer are discussed. Helicobacter pylori is an extremely successful pathogen that persistently colonizes the gut of about 50% of the world’s population. H. pylori and its human host share a long co-evolutionary relationship that dates back for at least last 100,000 years and possibly longer. Infection by this bacterium is a high-risk factor for the development of gastric diseases, including gastric cancer. Gastric cancer is associated with high morbidity and mortality and represents the 5th most common malignant tumour and the 4th leading cause of cancer-related death worldwide. H. pylori is the first bacterium that has been classified as a type-I carcinogen by the International Agency for Research on Cancer (IARC). Recent research progress identified crucial bacterial, host and environmental factors which control H. pylori-induced gastric malignancy. New studies also suggest that specific human germline mutations and other genetic aberrations have an important impact on H. pylori-induced pathology. In this volume, all these recently discovered mechanisms are reviewed in the light of gastric cancer development, and H. pylori epidemiology, virulence factors, immune evasion, pathophysiology, cancer signalling and novel therapeutic protocols are presented. This volume is aimed at researchers in the fields of immunology, genetics, microbiology and medicine who are interested in the detailed mechanisms of the pathogenicity of this carcinogenic stomach bacterium.

This e-book covers Helicobacter pylori research as it looks in 2014. The discovery of the bacterium in 1982 by B.J. Marshall and R. I. Warren had a tremendous impact on basic research and clinical medicine, resulting, in the past 3 decades, in more than 34,000 published articles. The editor of this volume and the contributing authors have compiled a unique collection of chapters dealing the with the microbiology, epidemiology, clinical diagnosis and treatment of H. pylori infections in a country-specific manner, with contributors having the opportunity to present the peculiarities and specifics of Helicobacter research in their area or country without overlapping any other previously published e-book. This e-book is a useful reference for gastrointestinal physicians and medical researchers seeking the latest information related to H. pylori.

There are few areas in medical science where the information explosion exceeds the capacity for a busy clinician to keep up to date. One such area is Helicobacter pylori. Since the first paper identifying H. pylori was published in 1983, great progress has occurred concerning H. pylori and its causal relationship to gastritis, duodenal ulcer, gastric ulcer and gastric cancer. In a field which is moving so fast, a lot of new information is continuously reported at medical meetings, often published only in abstract form, without further appearing in peer-reviewed journals. Even gastroenterologists, unless actively involved in the field of H. pylori research themselves, find it difficult to keep abreast of the field. Although several volumes and monographs have appeared on H. pylori, this book is the only one entirely devoted to the clinical pharmacology and therapy of the Helicobacter infection. It is clear that the real-world indications for H. pylori treatment are being broadened, and it is impossible to turn back the tide of prescribing by primary care physicians or gastroenterologists. Some effective and safe eradication regimens are available today but several new ones, often simple variations of an old scheme, are being proposed as equally effective and safe. This volume, which covers the treatment of all the H. pylori-related digestive diseases as well as the management of treatment failure and reinfection, will be a valuable reference text for all those physicians who pursue the cure of this common human infection.

Helicobacter pylori is an universally distributed bacterium which affects more than half of the world population. H. pylori infection causes persistent inflammation with different clinical outcomes in humans, including chronic gastritis, peptic ulcer disease and gastric cancer. The infection has also been associated with several extradigestive disorders. In this book there is a comprehensive overview of contributors on H. pylori infection in diverse areas, including virulence factors of H. pylori and their importance for the clinical outcome of the diseases, discussions about the principal therapeutic regimens of bacterium eradication, also considering the antimicrobial resistance. H. pylori is clearly a very interesting bacteria and great studies and discussions about all its aspects are welcome to the medical and scientific communities.

This book presents the current state of knowledge regarding the ability of Helicobacter pylori to colonize the gastrointestinal tract, the global epidemiology of H. pylori infection, transmission routes, the pathophysiology of H. pylori-related gastroduodenal and other diseases, diagnosis and treatment methods, guidelines for eradication, antibiotic resistance, the reinfection rate after H. pylori eradication, and animal models of H. pylori or related Helicobacter infection. The aim is to equip readers around the world with the understanding required in order to implement effective methods of H. pylori eradication and to enhance clinical outcomes for patients. The text is clearly written and is complemented by many helpful illustrations. This book will be a great asset in clinical practice for all practitioners who are involved in caring for patients with H. pylori-related diseases or have an interest in the subject. It will also be a useful source of information for medical students and for intelligent laypeople seeking information on H. pylori.
