Special Issue Information
Dear Colleagues,
Helicobacter pylori is considered the most common etiologic agent worldwide in adults and children. It infects 50% of humankind and represents the most important risk factor for gastric malignancies. The slow sequence, known as Correa’s cascade passes through a series of intermediated stages of precancerous lesions in the following order: gastritis, atrophy, intestinal metaplasia, and eventually dysplasia. Among infected individuals, approximately 10% develop severe gastric lesions such as peptic ulcer disease, 1–3% progress to gastric cancer (GC) with a low 5-year survival rate, and 0.1% develop mucosa-associated lymphoid tissue (MALT) lymphoma. The evolution versus different gastric diseases is correlated with H. pylori features, including genomic plasticity, capacity for adaptation to individual host conditions, modulation of the reaction to the host immune system response, and presence and production of various virulence factors; and with host factors, for example, genetic background or physiological and immunological state, especially those that enhance or reduce the inflammatory response to the infection. In addition, environmental factors such as smoking, diet, high salt, and meat consumption could be implicated.
This Special Issue has the goal to focus on new clinical, epidemiological, and experimental evidence as well as possible mechanisms of H. pylori and host factors involved in gastric and other diseases. Finally, it will review the known clinical indications for H. pylori vaccination.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
