Extra Digestive Disease and Helicobacter pylori Infection

Abstract

Helicobacter pylori infection has been associated with gastric pathology and gastric oncogenesis for many years, but its extra-digestive implications are less known. This chapter aims to provide up-to-date information on its potential role in neurological disease (Alzheimer’s disease, stroke, multiple sclerosis, Parkinson’s disease), dermatological disease (urticaria, rosacea, psoriasis), ophthalmological disease (glaucoma, chorioretinitis, blepharitis), hematologic disease (anemia, thrombocytopenia, neutropenia), as well as cardio-vascular disease (myocardial infarction, coronary atherosclerosis, hypertension), COVID-19, and metabolic pathology (diabetes mellitus, metabolic syndrome). For each group of diseases, a short description will be presented as well as information from published research. It will provide the reader with a global insight into the role of Helicobacter pylori in different pathologies.
