In most cases, the allergen that triggers this reaction cannot be identified and the urticaria is considered idiopathic. These results, however, have not been confirmed in all the studies (87–89); thus, the association between H. pylori infection and chronic urticaria is not established. Many new illustrations and electron micrographs are included in this edition, and the high-quality endoscopic and radiographic images permit ready correlation with the pathologic principles under discussion. Helicobacter pylori infection is a gastric infection that is common, worldwide, recognized as the main causative agent of chronic gastritis and peptic ulcer disease, and is closely associated with the development of gastric cancer. H pylori treatment should be prescribed to all patients with a positive test of active infection, and the selected treatment regimen should provide an eradication rate of at least 90%.

However, different confounders like unidentified socioeconomic factors, antibiotic use and others could bias the observed association. The mucosal barrier, IgE-mediated gastrointestinal events, and eosinophilic gastroenteritis. It has been shown, however, that gastric epithelium, like small intestine epithelium, is able to absorb small amounts of macromolecules (33–35) and that this antigen absorption may induce the IgE-mediated sensitivity reactions to these antigens (36). J Allergy Clin Immunol 1988; 81: 495–504. Although known to be the major cause of peptic ulcer disease and gastric cancer, disease occurs in a minority of those who are infected. Acta Gastroenterol Belg 1978; 41: 300–5. Analysis of several hundred pairs of twins shows that quantifiable traits associated with allergic diseases, such as total serum IgE levels and skin test results, show intrapairs correlation coefficients twofold higher for monozygotic than dizygotic twins (7).

The present review summarizes research data about the association between H. pylori and allergic diseases, as well as discusses possible hypotheses about the preventive action of H. pylori against atopy. The “attachment-effacement” lesions, associated with destruction of microvilli, cytoskeleton rearrangements, and pedestal formation by these cells were observed (62,63). In conclusion, our model of H. pylori-mediated asthma protection provides experimental support for the "disappearing microbiota" hypothesis , which postulates that the asthma and allergy epidemic of modern societies is a direct consequence of the disappearance of our ancestral indigenous microflora, which included H. pylori. Triple therapy including proton-pump inhibitors (PPIs) and two antibiotics, mainly amoxicillin and clarithromycin, constitutes the standard care for H. pylori infection treatment. In vivo, increased gastric permeability to sucrose was found in patients who tested positive for H. pylori(70,71). H. pylori may also have a role in uninvestigated and functional dyspepsia, ulcer risk in patients taking low -dose aspirin or starting therapy with a non-steroidal anti- Viney JL, Mowat AM, O'Malley JM, et al. Intragastral provocation under endoscopic control (IPEC) in food allergy: mast cell and histamine changes in gastric mucosa. Helicobacter pylori infections are usually established in early childhood and continuously stimulate immunity, including T-helper 1 (Th1), Th17, and regulatory T-cell (Treg) responses, throughout life. 24.

All parts of the digestive tract play a role in this process, the intestine considered a central part. Among several bacterial factors, the neutrophil-activating protein of H. pylori (HP-NAP) not only plays a key role in driving Th1 inflammation but it is also able to inhibit Th2 responses in vitro and in vivo in allergic bronchial asthma, in humans and mice.
