The aim of this study was to explore the prevalence of Helicobacter pylori infection in different surgical diseases in patients with six different cancer types. We analyzed sixty consecutive patients with malignancy (gastric cancer, pancreatic cancer, hepatocellular cancer, intestinal cancer, colon cancer, rectal cancer). Detection of specific IgA and IgG antibodies to Helicobacter pylori in hu...

The novel natural antibiotics pyloricidin A, B and C possess potent and highly selective antibacterial activity against Helicobacter pylori. In order to investigate the structure activity relationships for the terminal peptidic moiety, a series of pyloricidin B and pyloricidin C derivatives, bearing various amino acids in the moiety, were prepared and evaluated for their anti-H. pylori activity...

it has been also reported that that h. pylori infection may be responsible for some endocrine disorders, such as autoimmune thyroid diseases, diabetes mellitus and primary hyperparathyroidism. h. pylori which express cytotoxin-associated gene a (caga) may be more virulent than those that do not. the aim was to evaluate the seroprevalence of anti-h. pylori igg and anti-caga  antibodies in patien...

This study aimed to determine the seroepidemiology of Helicobacter pylori infection in Tepehuanos (an indigenous ethnic group living in rural Mexico). The prevalence of anti-Helicobacter pylori IgG antibodies was examined in 156 Tepehuanos in Durango State, Mexico, using an enzyme-linked immunoassay. In addition, sociodemographic, clinical, and behavioral characteristics of Tepehuanos associate...

In this study, a medicinal plant, Galla rhois (GR), was examined and screened for its anti-Helicobacter pylori activity. Galla rhois was extracted with 70% ethanol. Inhibitory zone tests, as in vitro assays, and an in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. The safety of the GR extract was then evaluated in an animal study. The Galla rhois extract demon...

pH stimuli sensitive microspheres of clarithromycin were prepared on the principle of cation induced gelification, whereas, sodium alginate and pectin blend were cross linked with calcium chloride and investigated with regard to drug targeting specificity in the gastric mucosa. The microspheres were found to be discrete, spherical, free flowing and of monolithic matrix type. The yields of micro...

[Objective] To explore the correlation between helicobacter pylori infection and several pathological features of gastritis, provide evidence for analysis diagnosis in associated gastritis. [Methods] We collected 180 patients with gastritis admitted to Seventh Affiliated Hospital Sun Yat-sen University from 2021 2022, make a retrospective their status H. PCR technology. Then we further detected...

Wei Tang Department of Surgery, Graduate School of Medicine, University of Tokyo, Tokyo 113-8655, Japan In this short correspondence, the authors hypothesized Helicobacter pylori infection may promote the development of immune response and thus improve survival rates of patients who have received complete resection of their tumors [1]. The authors based their hypothesis on the fact that patient...

BACKGROUND/AIMS We aimed to determine the etiology of patients with duodenal and gastric ulcers. METHODS 140 patients diagnosed with peptic ulcer between April 2002-2009 were enrolled in this prospective study. Two biopsy specimens were collected from the antrum and corpus for histology and one for rapid urease testing, and stool samples were analyzed for Helicobacter pylori antigen. Serum ca...

BACKGROUND Celiac disease has been reported to be associated with gastric abnormalities. The aim of this study was to assess the relationship between the prevalence of celiac disease and Helicobacter pylori infection in an Iranian population of 250 patients. METHODS Biopsies were taken from the gastric antrum and duodenum. Morphology and histology were evaluated using the updated Sydney syste...
