Background and Objectives: Although there are many studies that investigate the relationship between duodenogastric reflux (DGR) and Helicobacter pylori in adult patients, the reported data are contradictory. In addition, there are very few studies in the literature investigating the relationship between DGR and H. pylori in the pediatric age group. In the present study, we investigated the effect of primary DGR on H. pylori and gastritis. Materials and Methods: A total of 361 patients who were referred to the clinic of our hospital with dyspeptic complaints who had an upper gastrointestinal system endoscopy and a gastric biopsy were included in the study. Results: DGR was detected in 45 cases, and 316 cases that did not have DGR were considered as the control group. Comparisons were made between the DGR cases and the control group in terms of risk factors (age, gender), the presence and density of H. pylori, and the presence and severity of gastritis. The average age of the patients who were included in the study was 11.6 ± 4.6 years. A total of 128 (36%) of the cases were male and 233 (64%) were female. DGR was present in 45 (13%) of the cases. The average age of the patients with DGR was 13.9 ± 3.1 years, the average age of the control group was 11.3 ± 4.7, and there were statistically significant differences (p < 0.001). No significant differences were detected in terms of gender between DGR and the control group (p > 0.05). H. pylori (+) was detected in 29 (64%) of patients with DGR, and in 202 (64%) of the control group. No significant differences were detected between H. pylori prevalence (p = 0.947). Gastritis was detected in 37 (82%) of the patients with DGR, and in 245 (77%) of the control group (p = 0.476). No significant differences were detected between the presence and density of H. pylori, gastritis presence, severity and DGR (p > 0.05). Conclusions: The ages of patients with DGR were significantly higher than in the control group, and advanced age was shown to be a risk factor for primary DGR. It was found that the presence of DGR has no effect on the presence and severity of H. pylori. Given this situation, we consider it is important to eradicate H. pylori infection, especially in the case where H. pylori is present together with DGR.

Introduction. Helicobacter pylori (H. pylori) infection is known to be the must common cause of chronic gastritis having some endoscopic and pathologic characteristies as determinated by the Sydney System for Gastritis Classification. The aim of our case report was to point out the relationship between an endoscopic finding of nodular antritis and the presence of H. pylori infection and active chronic gastritis. Case report. Our patient underwent upper gastrointestinal endoscopy for dyspeptic complaints and was diagnosed as having nodular antritis, but also underwent urease test and hystopathologic examination of antral mucosa, to determine the presence and density of H. pylori infection and the presence and severity of gastritis. After a course of anti H. pylori treatment, dyspepsia improved and new biopsy specimens obtained two months and six months afterwards revealed no pathological findings. Conclusion. The case report supported the association of H. pylori infection of lymphoid follicles with nodular gastric mucosis.

4091 Background: The relationship between Helicobacter pylori (H.pylori) and hepatocellular carcinoma (HCC) was first proposed in 1994. Since then, several studies have been performed to explore the association. The role of Hepatitis C (HCV) viruses coexisting with H.pylori in causing HCC was also studied. With the emergence of data in this regard, a causal relationship has been postulated, but not confirmed, and hence the relationship remains controversial. Our meta-analysis aims to summarize the research on this topic and investigate if there exists a relationship between H. pylori infection and the development of HCC and if the presence of HCV along with H.pylori plays a role in liver carcinogenesis. Methods: Following PRISMA guidelines, we performed a systematic review of all relevant studies published in the literature using keywords “Helicobacter pylori” and “Hepatocellular carcinoma” on major literature databases, including PubMed, EMBASE, Web of Science, and Cochrane controlled trials register. A total of 656 studies were identified between 1994 to March 2020, out of which 26 studies qualified under our selection criteria. Patients positive for HCC are included as cases and patients that did not have HCC under control group. In both groups, H.pylori positive patients and their HCV status, was identified. Results: Out of the 26 studies included in the final analysis, the prevalence of H. pylori infection was 64.78% (561 of 866) amongst HCC cases and 47.92% (1718 of 3585) in the non-HCC control group. The summary odds ratio for the association of H. pylori infection with the risk for HCC using the random-effects model was determined to be 4.75 (95% CI, 3.06-7.37), I²=63%. Subgroup analysis to determine the odds of developing HCC in the presence of H.pylori and HCV coinfection, was 13.97 (95% CI, 3.94-49.61), I²=81%. Whereas, the odds of developing HCC in the presence of only HCV without H.pylori was found to be 2.21 (0.70-6.94), I²=79. Subgroup analysis by study design showed no significant difference between the study groups (P= 0.5705). Conclusions: Our meta-analysis showed a positive association between H. pylori infection and the development of HCC. It showed a significantly higher risk of developing HCC in the presence of HCV infection along with H.pylori. Further prospective cohort studies are needed to prove the causal relationship, especially in cases of Hepatitis B, C coinfection, and cirrhotic patients.[Table: see text]

Background: Helicobacter pylori is an important pathogen in the upper digestive tract. It is of great significance to properly understand the risk factors for the transformation of Barrett esophagus into esophageal carcinoma. However, the relationship between H. pylori and gastroesophageal reflux disease (GERD) and Barrett esophagus remains controversial, and the correlation with immune function has been rarely reported. Objectives: This study investigated the effect of H. pylori infection on Barrett esophagus and its correlation with immune function. Methods: We recruited 40 patients with Barrett esophagus (Barrett esophagus group) and 40 patients with GERD (GERD group). In addition, 40 healthy controls were selected for the control group. Esophageal function and its correlation with immune function were measured in each group. Results: The positivity rate of H. pylori (P < 0.05) and sphincter pressure were lower in both Barrett esophagus and GERD groups than in the control group, while the levels of PGI, PGII, PGI/II, and G-17 were higher (P < 0.05). The levels of CD3+, CD4+, and CD4+/CD8+ were lower in the Barrett esophagus group than in the GERD group, but they were negatively correlated (P < 0.05) with H. pylori infection. The level of CD8+ was higher in the Barrett esophagus group, and it was positively correlated (P < 0.05) with H. pylori infection. Conclusions: Helicobacter pylori infection may protect against Barrett esophagus by reducing gastric acid secretion and increasing lower esophageal sphincter pressure. Besides, it has a certain correlation with immune function.

Abstract Aim Helicobacter pylori (H. pylori) is one of the most common, well-known pathogenic agents in the development of peptic ulcers. Some investigators have shown a relationship between H. pylori and recurrent aphthous stomatitis (RAS). However, this relationship is controversial. The aim of this study was to determine the association between H. pylori and RAS using the urea breath test (UBT). Methods and Materials Forty-three patients with RAS and 44 non-RAS controls were evaluated. There were no differences in gender or age in the two groups. The UBT was used to detect H. pylori infection. Data were analyzed using the Chi Square Test. Results Sixteen individuals in the RAS patients (37.2%) and 14 individuals in the control group (31.8%) had a positive breath test. The difference was not considered statistically significant (p=0.597). Conclusion In the present study no statistically significant difference was found between frequency of a positive UBT in the RAS patients and the control group. Clinical Significance Since the probability of a positive test was higher in the more severe cases this factor needs to be considered in the diagnosis and treatment of RAS.

Objective To investigate the relationship between Helicobacter pylori ( H. pylori) infection and gallstones or gallbladder polyps. Methods This retrospective analysis included 27,881 individuals who underwent health examinations that included a H. pylori test and an abdominal ultrasound scan. Patients were divided into four groups: gallbladder polyp (P group), gallstone (S group), gallstone and gallbladder polyp (SP group), and no gallbladder disease (N group). Case–control matching was used to select the participants in the control group. Results The mean ages of participants in the P, S, and SP groups were all significantly higher than the mean age of participants in the N group. The proportions of participants with each type of body mass index significantly differed between the N and P groups, and between the N and S groups. In total 45.7% of participants exhibited H. pylori infection. After case-control matching, the proportion of participants with H. pylori infection did not significantly differ according to the presence or absence of gallbladder polyps. Similar results were observed regarding gallstones, as well as gallstones and gallbladder polyps. Conclusion H. pylori infection might not be related to gallbladder polyps or gallstones.

Introduction: In most individuals H. Pylori is acquired early in the life (before 5 years). H. Pylori infection is more common in the third world countries, where about 90% of adults may be infected. Helicobacter pylori is one of the suspected causes of halitosis in children. Objectives: To evaluate the relationship of helicobacter pylori and halitosis. Patients and Material: 33 patients with chief complaint of halitosis included in our study. Halitosis was evaluated as a subjective symptom in this study. Careful history was obtained. All patients underwent physical examination in order to rule out sinusitis, otitis, and possible cause of halitosis. 67 patients without halitosis were selected as control group. All patients were aged 4-17 years old. Urea Breath Test was done for all patients. UBT has >95% sensitivity and specifity for diagnosis of H.pylori infection. Chi-square test and Yate’s corrected x2 was used to analyzes finding. Epi-info ver 6 were used. Results: In the case groups 7 patients had H. pylori infection and 26 patients had not. In the control group 18 patients had H.pylori infection and 49 patients had not halitosis (P=0.53). Conclusions: There is no significant differences between case and control group. In this study we did not find relationship between H.pylori infection and halitosis.

Background. The proliferative lesions of the Brunner’s glands (BGs) are hyperplasia and hamartomas, and they are usually asymptomatic and very rarely diagnosed. The aetiology of these lesions is not yet clear. The aim of this study is to evaluate the clinical presentations of patients with BG hyperplasia and hamartomas and to assess the pathological features of these lesions in association with Helicobacter pylori (H. pylori). Methods. Our retrospective study included patients who underwent upper gastrointestinal system endoscopy between 2010 and 2015. The hospital records of 18 patients diagnosed with hyperplasia or hamartoma of BG were reviewed for the clinical and pathological findings. Data from patients with BG lesion were compared with 37 patients who had nonspecific duodenitis as the control group. Results. Female/male ratio in our study sample was 1/1. The age range was between 16 and 85 years with a mean age of 48.61. BG hyperplasia and hamartomas were found in 72.22 and 27.78% of the patients, respectively. The rate of H. pylori in gastric mucosa was 43.2% in the control group and 66.7% in the BG lesion group. In the BG lesion group, the rate of H. pylori was higher. H. pylori was identified in 60% of BG hamartomas and in 69.2% of hyperplastic BGs. Conclusion. Our study demonstrated that H. pylori may play an important role in the development of BG hyperplasia and hamartomas in association with chronic gastritis and duodenitis. This is probably due to chronic irritation.

Background. Several studies have shown a possible involvement ofHelicobacter pylori(H. pylori) infection in individuals with hyperemesis gravidarum (HG), but the relationship remains controversial. This meta-analysis was performed to validate and strengthen the association between HG andH. pyloriinfection.Methods. PubMed, Embase, and Web of Science databases up to March 20, 2014, were searched to select studies on the prevalence ofH. pyloriinfection between pregnant women with HG and the normal pregnant control subjects.Results. Of the HG cases, 1289 (69.6%) wereH. pylori-positive; however, 1045 (46.2%) wereH. pylori-positive in control group. Compared to the non-HG normal pregnant controls, infection rate ofH. pyloriwas significantly higher in pregnant women with HG (OR = 3.34, 95% CI: 2.32–4.81,P<0.001). Subgroup analysis indicated thatH. pyloriinfection was a risk factor of HG in Asia, Africa, and Oceania, especially in Africa (OR = 12.38, 95% CI: 7.12–21.54,P<0.001).Conclusions.H. pylorishould be considered one of the risk factors of HG, especially in the developing countries.H. pylorieradication could be considered to relieve the symptoms of HG in some intractable cases.

The relationship between infertility and Helicobacter pylori infection was investigated; samples from thirty-five infertile patients (aged 20-49 years) were collected from Kamal Al-Samaraei hospital , Baghdad, Iraq during the period from the first of February until April 2018. These patients were compared with 10 apparently fertile individuals who served as a control. The study was carried out to detect the DNA of H.pylori in both serum and seminal fluid of male infertile patients and for the control group by Real-Time Polymerase Chain Reaction (RT-PCR) technique. The results revealed that there was a significant difference (P<0.01) in the detection of DNA of H.pylori between patients and control groups. thereby the percentage level of H.pylori DNA in serum was 80% and in the seminal fluid was 0 %. As a result, we strongly suggest that the infection with H. pylori plays an important role in male infertility.

Abstract: Objective: Helicobacter pylori (H. pylori) is considered in the category of biological agent directly responsible for cancer. Guidelines recommend discontinuing suppressive conditions prior to histopathological helicobacter pylori testing, but there is little clinical trial data on how outcome is affected if this is not done. Optimal test recommendations in the guidelines are based on in vitro study results. In present study, we aimed to observe whether there was a difference in the prevalence of H. pylori histopathologically in patients who met the necessary prerequisites before Esophago-Gastro-Duodenoscopy (EGD) compared to the subjects group who did not meet the PPI discontinuation condition. Materials & Methods: This retrospective study was conducted between October 2015 and August 2016 in a reference hospital with 1.5 million hinterlands. Patients who underwent EGD by meeting all the prerequisites recommended by the guidelines for the H. pylori test were included in the study group (n=213), and those who discontinued other suppressive drugs except PPI were included in the control group (n=193). Results: While H. pylori was found to be 74.6% positive in the study group that provided all the prerequisites for histopathological H. pylori detection, H. pylori was found to be 64.9% positive in the control group continuing to receive PPI treatment (p=0.02). Conclusion: In conclusion, we suggest that it is necessary to proceed with the guidance of classical knowledge in determining the presence of H. pylori, which is a common public health problem that is up-to-date. Keywords: Helicobacter pylori, Suppressive condition, Proton pump inhibitor, Histopathology, Cancer, Guideline.
