“…In contrast to other studies, we did not find significant associations between H. pylori infection and age or level of education 22 , 23 . The lack of association for age may have been due to the fact that our sample had a higher mean age than that of other studies which have found this association 22 .…”

Objective: The aim of the study was to determine the relationship between fermented and unfermented dairy product consumption and Helicobacter pylori seropositivity in a Mexican population. Design: Dietary interviews were conducted as part of a population-based casecontrol study in 2005. Serum was obtained for each participant to determine H. pylori seropositivity status. Adjusted odds ratios were estimated from multivariate logistic regression models. Setting: Mexico City, Mexico. Subjects: A random sample of 464 healthy adult residents. Results: The overall seroprevalence of H. pylori in the study sample was 75.4%. In fully adjusted models, compared with those who did not consume yoghurt, there was a protective effect of eating up to one serving per week of yoghurt and more than one serving per week of yoghurt (odds ratio (OR) ¼ 0.57, 95% confidence interval (CI) 0.35 -0.94 and OR ¼ 0.45, 95% CI 0.24 -0.86, respectively), with a P for trend of 0.01. There were no effects for the consumption of unfermented dairy products (milk and cheese). Conclusions: This study suggests that yoghurt consumption may have a protective effect against H. pylori seropositivity. Additional studies are needed to determine whether consumption of yoghurt or other fermented dairy products can prevent or eradicate H. pylori infection.

“…Diferentes estudos mostram prevalências elevadas de H. pylori em populações de países em desenvolvimento, populações de baixo nível sócioeconômico, assim como em grupos etários mais jovens [23][24][25][26] . O papel da H. pylori nesse processo ainda não está claramente definido, mas o estimulo à multiplicação celular e a atração de polimorfonucleares representa hipóteses em investigação 22 .…”

Dieta e câncer gástrico: aspectos históricos associados ao padrão de consumo alimentar no estado do Pará

2006

View full text Add to dashboard Cite

O câncer gástrico ainda constitui importante problema de saúde pública no estado do Pará, onde as taxas de mortalidade apresentam valores acima da média brasileira. As bases históricas de ocupação de espaço na Amazônia, bem como as relações econômico-sociais estabelecidas ao longo desse processo, marcaram o padrão alimentar desse Estado. Este trabalho tem por objetivo reconstruir as principais características do padrão alimentar dessa população no século passado. Procurou-se identificar todas as publicações científicas disponíveis que relacionavam dados sobre os hábitos alimentares dos residentes do Pará no século XX. A partir dessas publicações, foi possível caracterizar o padrão alimentar da população paraense no século XX, que incluía um elevado consumo de sal, utilizado na conservação de carnes e frutos do mar, um consumo relativamente reduzido e irregular de legumes e verduras e uma importante ingestão de glicídios, a partir da farinha de mandioca, muitas vezes adicionada de corantes artificiais. O padrão de dieta retratado, provavelmente comum a outras regiões da Amazônia, pode ser caracterizado, com base na literatura científica, como potencialmente favorecedor de certas condições associadas à carcinogênese gástrica. Nesse sentido, ele poderia ter contribuído, em parte, para a alta mortalidade por essa neoplasia registrada na região Norte.

“…This infection is transmitted from person to person through oral-oral or fecal-oral routes during childhood in the past decades [31]. A study demonstrated that H. pylori is a helical or curved bacillus that colonizes the gastric mucosa and also transmitted in nonculturable coccoid [32]. It was first exposed and acknowledged in 1984 by Marshall and Warren, where it Paul et al…”

Objective:The aim of the study was designed to assess the mechanisms of antibiotic resistance in Helicobacter pylori, affecting disease by this infection and diagnostic methods which are used to detect H. pylori.Methods: A wide literature search was performed using PubMed, Medline, Cinahl, Embase, Educational Resources Information Center, PsycINFO, Google Scholar, Scopus, and Web of Science, and review of appropriate epidemiologic studies conducted from 1995 to 2017 for studies fully published investigating a contribution between H. pylori infection, antibiotic resistance, and diagnosis of H. pylori infection. Results:H. pylori infection is extremely contributed to the main symptoms and death that is currently affecting 50-75% of the people in the world. It is more affected in developing countries compared to developed countries. These infections are regarded to be the most important reasons for gastric cancer, peptic ulcer, chronic gastritis, duodenal ulcer, mucosa-associated lymphoid tissue lymphomas, and gastric adenocarcinoma. About 90-100% of duodenal ulcers and 60-90% of gastric ulcers were associated with H. pylori infections. At present, antibiotic resistance is a growing problem for the eradication of H. pylori infection; it contains metronidazole, amoxicillin, clarithromycin, and levofloxacin resistance. Diagnosis of H. pylori infection is a crucial part for the better treatment of those diseases. Different types of testing method for H. pylori infection are used including invasive (endoscopic image, histology, rapid urease test, and culture) and non-invasive (urea breath test, stool antigen test, and serological).Conclusion: H. pylori antibiotic resistance is the major contributor to the failure of H. pylori treatment. Appropriate diagnostic method selected in detecting H. pylori antibiotic resistance may lead to reduced treatment failures and less antibiotic resistance. Paul et al.Recent studies have shown that 13-labeled UBT ( 13 C-UBT) is a most reliable test for detection of H. pylori infection due to rapid, simple, innocuous, easy to repeat, reproducible, highly accurate, and economical manner [7]. Researchers have proved that this test is regarded as the gold standard, highest sensitivity and specificity (>95%), inexpensive, and convenient [64]. It was reported that the American College of Gastroenterology authenticated the carbon 13 C-UBT as the most consistent test to confirm H. pylori eradication (Fig. 7) [65]. Stool antigen non-invasive testAt present, studies have shown that this test is obtainable and suitable for small children, as well as this test is cost-effective and need to less apparatus than UBT [61]. It has been reported that this test can be performed mostly in routine laboratories and also used to provide after the end of H. pylori infection treatment [45]. CONCLUSIONH. pylori infection is one of the global problems which are more affected in developing countries than in developed countries, and major risk factors for gastric cancer and PU. Different methods are used to detect H....
