This book is a comprehensive overview of invited contributions on Helicobacter pylori infection in gastritis and gastric carcinogenesis. The first part of the book covers topics related to the pathophysiology of gastric mucosal defense system and gastritis including the gastroprotective function of the mucus, the capsaicin-sensitive afferent nerves and the oxidative stress pathway involved in inflammation, apoptosis and autophagy in H. pylori related gastritis. The next chapters deal with molecular pathogenesis and treatment, which consider the role of neuroendocrine cells in gastric disease, DNA methylation in H. pylori infection, the role of antioxidants and phytotherapy in gastric disease. The final part presents the effects of cancer risk factors associated with H. pylori infection. These chapters discuss the serum pepsinogen test, K-ras mutations, cell kinetics, and H. pylori lipopolysaccharide, as well as the roles of several bacterial genes (cagA, cagT, vacA and dupA) as virulence factors in gastric cancer, and the gastrokine-1 protein in cancer progression.

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.

Helicobacter pylori has attracted widening interest from basic scientists and clinical investigators and the information on this organism is increasing exponentially. It is now accepted that H. Pylori is the most important cause of chronic active gastritis. Furthermore, data have confirmed a marked reduction in the relapse rate of both duodenal and gastric ulcer after eradication of the organism. These important clinical observations have served as a strong stimulus to the investigation of the basic mechanisms involved in the pathogenesis of H. pylori-associated inflammation and the subsequent alterations of gastroduodenal function and gastric mucosal architecture. The book contains chapters by a multidisciplinary, international group of basic scientists and clinical investigators who focus on various microbiological aspects of H. pylori, on the role of H. pylori in peptic ulcer and gastric cancer, and the current status of therapy. The book contains the proceedings of the conference on `Helicobacter pylori: Basic Mechanisms to Clinical Cure', held at Amelia Island, Florida, U.S.A., on November 3--6, 1993.

Gastritis, as a medical term, exists for the last 150 years, however, terminology and etiology (including the prognosis ) has changed. Gastritis related medical problems are in the focus of different sub-disciplines: internists , gastroenterologists, pathologists, immunologists, bacteriologists, genetics, biologists etc. After the publications by Marshall and Warren most of the clinicians accepted only the etiopathological role of Helicobacter pylori in the development of gastric and duodenal ulcer , as well as in the gastric cancer. This book presents chapters abou the history of gastritis terminology, animal models, epidemiology, new gastric mucosal endogenous defensive neural mechanism (capsaicin-sinsitive afferentation), different research and clinical methods applied to the background studies and the molecular pathology, biochemistry and genetics involved in the pathways from Helicobacter pylori infection to development of gastric cancer. Intended audience of this book are internists, gastroenterologists, pathologists, bacteriologists, pharmacologists, genetics, biologists , immunologists and other interested researchers.

The book covers all aspects of endoscopic biopsies of the stomach inclusive of gastritis and gastropathies. It highlights the best way of handling of endoscopic biopsies in the endoscopic room by the gastroenterologist. It elucidates various steps involved in processing of the biopsy, tissue embedding and paraffin sectioning, approach to interpretation, various precautions that require to be taken while interpreting the biopsies, and the essential background knowledge of the interpreter. The book highlights the importance of the little things for a proper reading like matching of the tissue fragments received and the number of tissue present on a slide after the paraffin section. Chapters cover various forms of gastritis, and the easiest approach for daily routine by avoiding the cumbersome classifications and staging formulated for gastritis. It also discusses the utilization of the right nomenclature for acute and chronic gastritis and various other subtypes of gastritis. Chapters include various rarer and infrequently come across conditions of both acute and chronic gastritis, special form of gastritis and infective conditions. It also includes unusual forms of non-neoplastic gastric pathologies such as, a condition, where the gastric mucosa is affected not only by direct exposure to various irritants but may also be affected by many systemic diseases. It also highlights the frequently observed changes in chronic renal and liver failures. The book is targeted to all the practicing pathologists as well as graduate and post graduate students who are keen to learn about non-neoplastic gastric pathology at various levels.

This book provides a detailed review of the most recent pathogenetic, diagnostic and therapeutic approaches in connection with Helicobacter pylori, along with priority areas in research and trends in clinical practice to address this significant pathogen acknowledged as the causative agent in a wide range of diseases, including gastric adenocarcinoma, MALT lymphoma and immune thrombocytopenic purpura (ITP). Medical authorities worldwide now recommend a “test and treat” strategy for this bacterial infection. Eradication therapy approaches range from general mass eradication therapy to tailor-made therapy for antibiotic-resistant refractory infection. In regions with high prevalence of H. pylori infection, the infection itself would be considered a major parameter to predict the risk of gastric adenocarcinoma development. The main interest has shifted recently to the risk stratification strategy for gastric cancer development and to the wide-ranging application of its serological prevention program. This book will benefit all gastroenterologists, hematologists, dermatologists, primary care doctors, epidemiologists, physicians who related with community hygiene, as well as basic scientists, particularly microbiologists, bacteriologists, pathologists, molecular biologists, biochemists, immunologists and oncologists.

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.
