“…19,20 Recent studies have shown that H. pylori is also isolated from dental plaques, human saliva, duodenum, feces and atherosclerotic plaques, and is strongly associated with the extragastrointestinal disorders such as idiopathic thrombocytopenic purpura, neurological disorders (stroke events), psychiatric, gynecological, pre-eclampsia, infertility, glaucoma, dermatologic complications, lung cancer, iron deficiency anemia, autoimmune diseases, and atherosclerosis. [21][22][23][24][25][26][27][28][29][30][31][32][33] Unfortunately, the rate of colonization with H. pylori is high worldwide, especially in Asia (from 25%-50% in developed countries to 90% in developing countries); the eradication of H. pylori infection has decreased in recent years due to problems such as elimination of antibiotics in acidic gastric conditions, bacterial infiltration under the gastric mucosa, and antibiotic resistance. [34][35][36] According to studies, the rate of gastric cancer in Asia is higher than Western countries, and many researchers attribute this to the high colonization with H. pylori in this geographical area.…”
