“…Gastric acid secretion in the elderly appears to be impaired compared with younger individuals due to e.g. atrophic gastritis [14,15], resulting in a slower return to baseline levels after pH-level disruption [16], and probably in an increased probability of pathogen passage to the intestines [17]. The effect of PPI prescriptions on this probability may therefore be smaller than in younger age groups.…”

“…Recentemente, alguns trabalhos mostram que a infecção pelo H. pylori poderia ter um efeito protetor contra a doença (17,18,33,45,57) . De modo complementar, mostrou-se que pacientes infectados por linhagens mais virulentas (cagA+, vacAs1) estariam inversamente associados com o desenvolvimento da doença.…”

“…Por um lado, postula-se que este efeito deva-se à redução da secreção ácida gerada pela infecção por linhagens mais virulentas (51,57) , por outro acredita-se que, além dos fatores de virulência da bactéria, alguns fatores genéticos do hospedeiro devem contribuir nesta proteção (45) . Na presente série, detectou-se uma associação entre a presença de linhagens menos virulentas com esta doença ao se comparar o genótipo s2 do gene vacA da bactéria com o desenvolvimento de esofagite de refluxo, assim como observado por outros autores (18,32,44,57) .…”

“…Ageing is typically accompanied by a milieu of changes including substantiated alterations and deterioration of gut functions, such as secretion of digestive fluids and enzymes, saliva, GIT contractions and chyme passage rates (Di Francesco et al, 2005;Feldman, Cryer, McArthur, Huet, & Lee, 1996;Laugier, Bernard, Berthezene, & Dupuy, 1991;Nagler & Hershkovich, 2005;Russell et al, 1993;Salles, 2007;Vellas et al, 1988). Due to the irreversible nature of the changes in GIT functions, there is a growing need to deepen our understanding of foods' digestive fate in the elderly GI.…”
