Helicobacter Pylori In The 21st Century

This book provides a broad overview of the current understanding of Helicobacter pylori emphasizing its world health impacts. It includes 13 chapters organized into 3 parts: "Pathologies and Treatment", "Host Response" and "Bacterial Defence". Part I (5 chapters) reviews the epidemiology of H. pylori infection, H. pylori infection in Asia, gastric adenocarcinoma, antimicrobial resistance and approaches to treatment, and extragastric manifestations of H. pylori infection. Part II (4 chapters) describes H. pylori-induced acquired immunity and immunoregulation, host genetic factors and susceptibility to H. pylori pathogenesis, innate immune initiators and effectors in H. pylori infection, and H. pylori vaccines. Part III (4 chapters) discusses the importance of H. pylori lipopolysaccharides in gastric adaptation and pathogenesis, H. pylori virulence factors, H. pylori adhesion to the gastric surface, and helicobacteromics. This book is an essential resource for researchers, students and medics in infectious and Helicobacter-associated diseases.

A century ago the Italian pathologist Bizzozero described the relationships between spiral bacteria and the mammalian gastro intestinal tract. Since 1982, when Helicobacter pylori was discovered, gastroduodenal disease have been completely revised as a con sequence of the results of basic and clinical research in this field. Progress in understanding the pathogenesis of this bacterium has been made by studying H. pylori infection in animal models. More specific diagnostic tools have been developed using new molecular biology techniques. Future trends are directed towards preparing a specific H. pylori vaccine. A new classification for gastritis, the Sydney System, including H. pylori gastritis, was proposed in 1990. As concerns the clinical approach to peptic ulcer disease in the 1990's, the majority of authors agree on the importance of H. pylori eradication. Moreover, recent clinical studies suggest that H. pylori infection can be associated with other gastroduodenal diseases, such as non ulcer dyspepsia and gastric cancer. Multicenter trials to standardize serological methods and evaluate the efficacy of new antimicrobial therapy schedules are planned throughout different European countries. The fourth Workshop of the European Helicobacter Pylori Study Group was held in Bologna, Italy, in November 1991. Two years before Bologna University celebrated its ninth centennial, giving evidence of being the oldest University in the modern world. Thus the H. pylori story that has continued for more than a century has been discussed once again at the University with the oldest tradition in the world.

Helicobacter pylori is a globally significant pathogen that infects half of the population of the world. Providing a broad overview of the understanding of this pathogen, this book explores a range of topics including virulence factors, vaccine development and obstacles, epidemiology, antibiotic resistance and the role of Nod receptors.

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.

The 20th century has seen improvements in both public health and disease prevention which, in turn, have had a dramatic impact on our lives. Success in preventing infection by vaccination and treating infection with antibiotics led some to believe that infectious disease was a thing of the past. However, the adaptability of pathogens and the emergence of new diseases has presented microbiologists with a fresh set of challenges as we enter the new millennium. While celebrating past successes and highlighting developing problems, this volume aims to address some of the issues facing microbiologists in the future. Covering a wide range of topics, it will provide an invaluable resource for microbiologists and an excellent reference for advanced students.

This book gathers a wealth of contributions on the virulence factors and pathogenic mechanism of Helicobacter pylori, prepared by leading international experts. In addition, it explores the epidemiology, diagnosis, treatment with drugs and probiotics, and prophylaxis by vaccination, reflecting the latest advances. H. pylori is a Gram negative microaerophilic bacterium that can produce various gastric diseases including gastritis, gastroduodenal ulceration, gastric cancer and gastric MALT lymphoma. Although efforts to combat H. pylori using a combination of proton pump inhibitor and several antimicrobial drugs have significantly decreased the burden of these gastric diseases, the microbial epidemiology and gastric pathogenesis following H. pylori infection are still not fully understood. Given its scope, the book offers a valuable resource not only for basic microbiologists, but also for researchers in the fields of pathology, biochemistry and genomics, as well as medical students/scientists.

Vaccines have made it possible to eradicate the scourge of smallpox, promise the same for polio, and have profoundly reduced the threat posed by other diseases such as whooping cough, measles, and meningitis. What is next? There are many pathogens, autoimmune diseases, and cancers that may be promising targets for vaccine research and development. This volume provides an analytic framework and quantitative model for evaluating disease conditions that can be applied by those setting priorities for vaccine development over the coming decades. The committee describes an approach for comparing potential new vaccines based on their impact on morbidity and mortality and on the costs of both health care and vaccine development. The book examines: Lessons to be learned from the polio experience. Scientific advances that set the stage for new vaccines. Factors that affect how vaccines are used in the population. Value judgments and ethical questions raised by comparison of health needs and benefits. The committee provides a way to compare different forms of illness and set vaccine priorities without assigning a monetary value to lives. Their recommendations will be important to anyone involved in science policy and public health planning: policymakers, regulators, health care providers, vaccine manufacturers, and researchers.
