    Does the Urea Breath Test Predict Eradication of Helicobacter Pylori Infection
    (2016) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Gokturk, Huseyin Savas; Durukan, Elif; Erhamamci, Seval; https://orcid.org/0000-0003-0182-002X; https://orcid.org/0000-0002-8579-5564; 26852756; AAJ-8621-2021
    Background/Aim : Helicobacter pylori infection is common world-wide and has been linked to development of gastric and duodenal ulcers, gastric adenocarcinoma, and gastric lymphoma. However, antimicrobial resistance has decreased H. pylori eradication rates worldwide. This study aimed to evaluate the effect of-bacterial load on eradication rate. Method : This prospective study included 237 consecutive patients who presented to our institution with dyspeptic symptoms and underwent both upper endoscopy and urea breath tests (UBT). The patients were divided into three equal sized groups according to their UBT values. All subjects received a standard triple eradication regimen, followed by a bismuth-based quadruple eradication regimen if triple eradication was not successful. The three groups were compared with respect to age, endoscopic findings, sex, and eradication rates. Results : Our results were consistent with those of previous studies : higher UBT values were associated with failure of standard 14-day triple treatment (p < 0.05). However, in patients who received a quadruple eradication regimen, differences between groups were not significant (p = 0.434). There was no relationship between UBT values and gastric pathologies (p = 0.751). Age and sex also did not differ significantly between groups (p = 0.061). Conclusions : Our study and others have found that high bacterial loads are negatively associated with achievement of eradication with triple treatment. However, differences between groups were not significant in patients who received a quadruple eradication regimen. Comparisons of treatment results according to bacterial density may be informative. The importance of H. pylori density should be further evaluated with new treatment protocols.

    BackgroundThe H. pylori eradication success is low in countries with high antibiotic resistance to H. pylori. ObjectiveWe retrospectively assessed the eradication rates achieved by five different regimens and aimed to compare the efficiency of bismuth enhanced sequential therapy and other treatments in a gastroenterology outpatient clinic a university-affiliated hospital. DesignOur study was carried out with a retrospective cohort design. SettingThis study assessed the gastroscopy examinations of patients. PatientsA total of 621 patients were included in the study. There were 122 patients in the quadruple treatment group, 168 patients in the classical sequential treatment group, 130 patients in the bismuth enhanced sequential therapy, 113 patients in the sequential treatment with levofloxacin, and 88 patients in the hybrid treatment. MeasurementsEradication rates of different regimens was analyzed by performing Chi-square and Tukey's honest significant difference test. ResultsEradication rates by ITT and PP analysis achieved by treatment groups were 74.6 and 75.6% in the quadruple treatment; 70.2 and 70.4% in the sequential treatment with clarithromycin, 88.5 and 90.3% in the bismuth enhanced sequential therapy, 77.9 and 78.5% in the sequential treatment with levofloxacin, and 76.1 and 76.2% in the hybrid treatment. LimitationsThe main limitation of our study was its retrospective nature. Different proton pump inhibitors were used in the treatment arms. ConclusionsBismuth-enhanced sequential therapy can be recommended to overcome resistance.

    Is there any association between colonic polyps and gastric intestinal metaplasia?
    (2016) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Gokturk, Huseyin Savas; Korkmaz, Huseyin; Erinanc, Ozgur Hilal; 27210777
    Background/Aims: Chronic gastritis progression is a multistep process of atrophy, intestinal metaplasia (IM), and dysplasia, which may lead to invasive carcinoma. In this study, we identified an association of colonic polyps with gastric IM in patients undergoing colonoscopy. Materials and Methods: This retrospective case-control, cross-sectional study was conducted in a tertiary-care institution in Turkey. Pathology and endoscopy reports were reviewed. The study group comprised 400 patients with colonic adenomatous polyps, and the control group comprised 360 patients without colonic adenomatous polyps on colonoscopy. Results: The risk of gastric IM was 1.42-fold higher in the study group (p<0.05). The risk of IM in patients aged >= 50 years with colonic polyps was 3.35-fold higher than in those aged <50 years (p<0.05). The risk of Helicobacter pylori infection in the study group was 1.07-folder higher than that in the control group (p<0.05). H. pylori infection prevalence was higher only in patients with high-grade colonic polyp dysplasia (p<0.05). There were no statistically significant differences in the proportion of incomplete IM between the groups (p<0.05). Conclusion: This study observed increased rates of gastric IM with colonic polyps. An increased risk of gastric IM was associated with higher grades of polyp dysplasia.
