Opis:
Purpose: The role of Helicobacter pylori (Hp) in the development of gastroesophageal reflux disease (GERD) remains disputable. This study was planned to determine clinical-epidemic correlations between reflux esophagitis (RE) and Hp in older children. Materials and methods: 308 children with RE and 418 patients with chronic gastritis (CG) without RE between the ages of 12 and 18 were examined. Hp was diagnosed by histological (Giemsa and hematoxylin-eosin stain, with evaluation of dissemination grade) and rapid urease test. Subjective symptoms (heartburn, abdominal pain, other dyspeptic complaints) were analyzed by questionnaire. Results: Hp infection was found in 44.5% of children with RE (no difference in patients without RE), and it does not increase the erosive esophageal defects risk. Clinical symptoms are not connected to this infection in examined patients. The frequency of Hp infection decreases with the disease duration increase. Conclusion: The development of RE is not connected with Hp, but the disease course has certain peculiarities in the conditions of Hp infection.

Opis:
Helicobacter pylori is an etiological agent of chronic gastritis, gastric and duodenal ulcers and gastric cancers. The use of an appropriate animal model for experimental studies on the pathogenesis of H. pylori infections is necessary due to the chronic character of such infections and difficulties in identifying their early stage in humans. The aim of this study was to develop a guinea pig model of H. pylori infection and identify its microbiological, histological, serological and molecular determinants. Guinea pigs were inoculated per os with H. pylori strains: CCUG 17874 or ATCC 700312, both producing vacuolating cytotoxin A (VacA) and cytotoxin associated gene A (CagA) protein, suspended in Brucella broth with fetal calf serum (FCS) and Skirrow supplement of antibiotics. To determine H. pylori colonization, 7 and 28 days after the challenge, a panel of diagnostic methods was used. It included culturing of microorganisms from the gastric tissue, histopathological analysis of gastric sections, stained by Mayer,s haematoxylin and eosin to assess inflammatory response, by Giemsa as well as Warthin-Starry silver staining to visualise Helicobacter-like organisms (HLO) and with anti-Ki-67 antigen to assess epithelial cell proliferation. H. pylori infection was also confirmed by polymerase chain reactions (PCR) for detection in gastric tissue of ureC and cagA genes and by serological assessment of H. pylori antigens in faeces. This study showed the usefulness of microbiological, histological, immunological and molecular methods for the detection of persistent H. pylori infections in guinea pigs, which could be an appropriate model for studying H. pylori pathogenesis and the related immune response against these microbes.

Opis:
Gastric cancer with the annual mortality of 700 000 is the second cause of death in the world. Iran with the annual incidence of 37 in 100 000 is among areas with high risk of gastric cancer. In Iran, Khuzestan Province with the annual incidence of 10 -15 in 100 000 is among areas with moderate risk. The role of Helicobacter pylori infection in distal gastric cancer as one of the most important risk factors of gastric ulcer has been proved but its role in proximal gastric cancer is controversial. In recent decades, the incidence of proximal cancers has increased. The aim of the study was to survey the relative frequency of Helicobacter pylori infection in the people with proximal cancer and to compare it with this infection frequency in the distal cancer. Material and methods. Relative frequency of Helicobacter pylori infection was surveyed by pathology tests and biopsy gastric mucosa sample staining with H&E in the patients with proximal and distal gastric ulcer whose cancers were proved by pathology method and also in the people who were healthy in terms of a gastric cancer. Data were statistically analyzed by frequency tables and chi square test. Results. One hundred and seventeen people entered the study. Among 32 patients with the proximal cancer, 21 people were with the positive Helicobacter pylori (65.6%) and 11 people (34.4%) were with the negative Helicobacter pylori (p<0.01). Among 30 patients with the distal cancer, 26 people were with positive Helicobacter pylori (86.7%) and four people were with negative Helicobacter pylori (13.3%) (p<0.01); 55 people were without the cancer, which among them, 40 people were with the positive Helicobacter pylori (72.7%); and 15 people were with the negative Helicobacter pylori (37.7%) (p<0.01). In comparison of the frequency of Helicobacter pylori infection in the patients with the proximal cancer, a weak significant difference exists (p = 0.053). Comparing the frequency of Helicobacter pylori infection in the patients with the gastric cancer and people without the cancer, no significant difference existed (p = 0.703). Conclusion. A weak significant difference existed between the frequency of Helicobacter pylori infection in patients with the proximal gastric cancer and the frequency of these infections in the patients with the distal cancer. So, eradicating Helicobacter pylori infection can be effective in preventing the distal gastric cancers in addition to preventing the proximal gastric cancers.
