Introduction. Helicobacter pylori is a bacterium that has been in the limelight of gastroenterologists and oncologists worldwide since its immediate effect on the development of gastritis, ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer was proved. The aim of this study was to determine the correlation between the positive immunological test, rapid urease test and pathohistological finding in detecting Helicobacter pylori infection of the gastric mucosa. Material and Methods. This retrospective study included 250 endoscopic findings of subjects having undergone endoscopy in the first half of 2010 at the Ward of Gastroenterology, Department of Internal Diseases, Hospital in Senta. The endoscopy procedure was performed by Fujinon endoscopes and the fast urease test was done by the Cambridge Life Science set from England. The immunological test was carried out by the Vidas apparatus applying the Enzyme-Linked Fluorescent Assay (ELFA) technique and the staining for the pathohistological analysis was done by the modified Giemsa method. Results. The paper presents the results obtained by endoscopic examination of a group of 250 patients performed at the Ward of Gastroenterology, Department of Internal Diseases, Hospital in Senta. The endoscopic findings were the first to be analyzed then the rapid urease test findings, which showed that 95 (38%) patients were positive and 155 (62%) patients were negative; whereas the immunologic test for Helicobacter pylori was positive in all 250 patients (100%). The histological test for Helicobacter-Like Organism was positive in 105 subjects (42%), whereas it was negative in 145 patients, that being 58% of all the cases. Sensitivity, specificity and predictability of the serological test and the rapid urease test were calculated according to the pathohistological finding as the ?gold standard? and they were found to be: sensitivity 100% and specificity 0% for the serological test and sensitivity 90% and specificity 100% for the rapid urease test. The immunologic test was not correlated with other findings, and there was a high level of correlation between the rapid urease test and histological test (r=0.927589261). The t-test was calculated to be 36.16513; p=0.0001; that indicating that the correlation coefficient was statistically significant (p>0.01). Discussion. The obtained results were compared with the data found in the available literature sources. Conclusion. It can be concluded that the most competent technique for the optimal diagnosis of Helicobacter pylori infection is the invasive one with the pathohistological examination of bioptates together with the rapid urease test.

The multicenter prospective observational study initiated by the European Helicobacter and Microbiota Study Group (EHMSG) is conducted in 27 countries in Europe. The data from the Russian part of the European registry for the management of Helicobacter pylori infection (European Registry on the management of Helicobacter pylori infection, protocol: “Hp-EuReg”) allows us to analyze the real clinical practice of diagnosis and treatment of H. pylori and compare it with international recommendations. Materials and methods. A comparative analysis of the data entered in the register by the Russian research centers “Hp-EuReg”, in the period from 2013 to 2018, was conducted. Results and discussion. Invasive diagnostic methods prevail for the primary diagnosis of H. pylori [histology - 20.3% (in 2013 year) - 43.9% (in 2018 year), rapid urease test - 31.7% and 47.8% respectively]. The most popular mode of eradication therapy is a 10-day triple therapy (62.8-76.2%), the effectiveness of which does not exceed 79% (per protocol). Invasive tests (histology) are the leading method for control the effectiveness of therapy, however, there is a tendency towards a wider use of non-invasive methods (H. pylori stool antigen - from 17% in 2013 to 29.3% in 2018 and urea breath test from 6.9 to 18.3%, respectively). Serological test to control the effectiveness of eradication is still used from 8.2% (2013) to 6.1% (2018). Eradication therapy was not performed in 28% of patients throughout the entire observation period. Conclusion. In Russia, despite approved domestic and international recommendations, deviations in clinical practice persist, both during eradication therapy and in monitoring the effectiveness of eradication therapy.

Review question / Objective: Is gastric helicobacter pylori infection related to periodontal diseases? Condition being studied: Therefore, the aim of this systematic review and meta-analysis was to identify and analyze clinical studies to determine the direct correlation between Helicobacter Pylori gastric infection andPeriodontal Disease. Study designs to be included: Clinical studies that provided data on Helicobacter Pylori infection in both the stomach and oral cavity, confirmed by polymerase chain reaction (PCR), rapid urease test (RUT) or enzyme-linked immunosorbent assay (ELISA). Clinical studies that associated PD with Helicobacter Pylori. The diagnosis of PD was confirmed ac-cording to the diagnostic criteria in periodontology.

Background. As part of an observational multicenter prospective study European Registry on the management of Helicobacter pylori infection, conducted on the initiative of the European H. pylori and Microbiota Study Group, the compliance of clinical practice in the management of patients with Helicobacter pylori infection in Kazan with clinical guidelines was assessed. Materials and methods. The data of 437 patients included into the register by clinical sites in Kazan in 20132019 were analyzed. The methods used for the initial diagnosis of H. pylori infection and eradication control were evaluated. The frequency of various eradication therapy regimens prescription was analyzed in 379 cases. Data regarding the effectiveness of eradication therapy was analyzed in 173 patients. Results. The rapid urease test (44.2% of cases) and cytology/histology (60% of cases) were most often used for the initial diagnosis of H. pylori infection; however non-invasive methods such as 13C-urea breath (9.2%), serology (6.2%), H. pylori stool antigen test (2.3%) were less common. In 21.7% of patients two methods of H. pylori detection were used for primary diagnosis. The control test to evaluate the effectiveness of eradication therapy at the recommended timepoint was performed in 46.2% of patients. 13C-urea breath test (31.7%), stool PCR/stool antigen test (28.7%), rapid urease test (22.3%), cytology/histology (26.2% of cases) prevailed in the assessment of eradication rate. Standard triple therapy, including proton pump inhibitor, clarithromycin and amoxicillin was most commonly prescribed as first-line therapy (64.6% of cases). The duration of eradication therapy was 14 days in the majority of cases with pantoprazole as the most common proton pump inhibitor in standard triple therapy regimens (84.8%). The efficacy of 14-day standard triple therapy (mITT) was 87.0%. Conclusion. The results indicate a high frequency of non-invasive methods use for assessing the effectiveness of eradication therapy; however, the overall rate of eradication efficacy assessment is low, limiting the possibility of analyzing the eradication results. The effectiveness of the most common 14-day standard triple first-line therapy in Kazan doesnt reach the recommended 90% eradication level. This could be explained by high rate of pantoprazole use, which is not an optimal proton pump inhibitor in eradication therapy regimens.
