As well as peptic ulcers, Helicobacter pylori is associated with the development of gastritis, gastric adenocarcinoma and lymphoma, and has been classified as a class I carcinogen in humans (International Agency for Research on Cancer Working Group, 1994). Although the bacteria can be eradicated in up to 90% of patients, side effects, poor compliance and the resistance of the bacteria to antibiotics are common causes of frequent treatment failure. Celery seed extracts (CSE) from a unique source in India has been used as herbal medicine since antiquity and found to have anti-inflammatory and ga

Helicobacter pylori (H. pylori) infection causes achlorydria, depressed gastric acid barrier, impaired immune response and is suspected in bacterial overgrowth and diarrhoea. These features of the infection are known to cause significant malabsorption of nutrients and impairment of linear growth in children. The prevalence of H. pylori infection in children is known to be much higher in developing countries, especially among the lower socio-economic groups. The true prevalence of infection in urban children in Mexico and its impact on their growth are largely unknown. This study examined the p

More than half of all people worldwide are infected with H. pylori. The infection always cause a gastric inflammation that may develop into peptic ulcer disease or gastric cancer.

Large numbers of people carry this organism asymptomatically and many questions remain about why serious symptoms develop in a subset of infected humans. These extremely recombinant bacteria may take different evolutionary trajectories in different people, and some genomic changes may be associated with gastric cancer.

Indeed, APRIL and BLyS are involved in the maturation of B cells, but, most importantly, they increase the survival and proliferation of these cells.

Being among the most prevalent of persistent infectious agents in humans worldwide, Helicobacter pylori induces chronic inflammation (gastritis), which may progress to peptic ulceration and stomach cancer. The ability to adhere to the gastric mucosa is considered to be both a colonization and virulence property of H. pylori. For adherence, H. pylori expresses surface-located attachment proteins (adhesins) that bind to specific receptors in the gastric mucosa. The best characterized H. pylori adhesin-receptor interaction is that between the blood group antigen binding adhesin (BabA) and the fuc

Streszczenie:

Campylobacter jejuni and Helicobacter pylori are pathogens which cause gastrointestinal diseases and are therefore of significant importance. However, their metabolism and physiology is relatively poorly understood. It had been noted that the genome of these pathogens lack open reading frames for some glycolytic enzymes. Notably, both pathogens lack the gene encoding phosphofructokinase (6-PFK) and thus regulation of the complementary gluconeogenic enzyme fructose-1,6-bisphosphatase (FBPase) might be different to that in the majority of organisms which retain 6-PFK.

H. pylori treatment failure is a growing problem in daily practice. Aim: to evaluate and compare the efficacy of two new regimes as second-line options in a randomized, prospective study. Methods: Patients previously submitted, without success, to clarithromycin-based regimes were included. 13C-urea breath test (UBT) was performed in all patients. The patients were randomized to receive a combination of rabeprazole 20mg, levofloxacin 500mg and furazolidone 200mg (2 tablets) administered in a single dose for 10 days (RLF) or the association of rabeprazole 20mg, bismuth subcitrate 120mg (2 table

Introdução e objetivos: Eosinofilia duodenal está associada com parasitoses intestinais e com alergias alimentares, e tem sido sugerida como possível fator etiológico da dispepsia funcional, pela capacidade de causar alterações na motilidade e na sensibilidade do aparelho digestivo. Sua relação com o Helicobacter pylori é pouco conhecida, tendo sido avaliada apenas como achado secundário em alguns estudos, com resultados controversos. Esse estudo tem como objetivos avaliar o papel da infecção gástrica pelo H. pylori no número de eosinófilos duodenais e avaliar a relação dos eosinófilos duodena

To elucidate the molecular mechanisms involved in persistency/latency of the H. pylori infection or in its progression towards serious diseases, it is necessary to analyse the host pathogen interaction in vivo. The circulating antibody repertoire represents an important source of diagnostic information, serving as biomarker to provide a “disease signature”. The aim of this work is the identification of H. pylori epitopes responsible for host immunoresponse modulation through: a discoverydriven approach that couples “phage display” and deep sequencing (interactome-sequencing) and the develo

Helicobacter pylori (H.pylori) had been confirmed by the World Health Organization (WHO) as Group 1 carcinogens, in which it has been identified to be related with the development of gastric carcinoma. Gastroesophageal reflux disease (GERD) is less commonly found in Asia, while the number of H.pylori infection is considerably to be higher than that of the Western population. The relationship between H.pylori and GERD still remains ambiguous nowadays. One of the contributing factors affecting the level of gastric secretion might be due to the genetic cause. The aim of this review is to assess
