Brunner’s Gland Hyperplasias and Hamartomas in Association with Helicobacter pylori

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 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.

Upper Gastrointestinal

Helicobacter pylori is a microaerophilic, gram-negative bacterium found in the upper gastrointestinal tract of humans. There is strong evidence that H. pylori is important in the etiology of gastritis; the bacterium may also be a major predisposing cause of peptic ulceration. On the gastric mucosa, the organism exists as a spiral form with one to seven sheathed flagella at one (usually) or both poles. Short spirals were seen in the first successful culture of the organism in 1983. In 1984, Marshall and Warren reported a coccoid form in older cultures. Since that time, other workers have observed rod and coccal forms in vitro; coccoid forms predominate in cultures 3-7 days old. We sought to examine the growth cycle of H. pylori in prolonged culture and the mode of coccoid body formation.

Sjögren‘S Syndrome

Background and Aim: Lymphoid cell infiltration and destruction of exocrine glands, specifically lacrimal and salivary glands are characteristics of Sjogren’s syndrome (SS). An etiological role has been proposed for Helicobacter pylori (H. pylori), interacting in the clinical course and complications of SS (including gastric cancer and lymphoma). The aim of this study was to identify the probable correlation between H. pylori infection and Sjogren’s syndrome (SS). Methods: In this case-control study, ELISA method was used to determine serum level of IgA and IgM anti H. pylori antibody in 43 subjects with SS according to the international criteria and 95 healthy subjects as control. SPSS-17 was used to analyze data with t-test. P value <.05 were considered significant. Results: Serum level of IgM (34.9% vs. 10.5%, p-value= 0.001) and IgA (67.4% vs. 46.3% p value= 0.021) anti H. pylori antibody were significantly higher in SS patients compared to the control group. There was a positive correlation between age and H. pylori infection (r=0.2, Pvalue= 0.05). Conclusion: Patients with SS had a higher prevalence of H. pylori infection compared to the normal population. Eradication of H. pylori is recommended particularly in older patients with SS.

AbstractObjectiveThis study aimed to examine nasal mucociliary clearance time in patients with Helicobacter pylori infection.MethodsFifty patients who were newly diagnosed with H pylori infection using gastric biopsy in the gastroenterology out-patient clinic, and 50 age- and gender-matched healthy adults who were admitted to the otorhinolaryngology out-patient clinic, were included in this study. After an otorhinolaryngological examination (anterior rhinoscopy and nasal endoscopic examination), the nasal mucociliary clearance time of each subject was calculated using the saccharine test.ResultsThe mean mucociliary clearance time was 06:29 ± 3:31 minutes (range, 00:55–15:19 minutes) in the control group and 10:12 ± 06:09 minutes (range, 01:28–32:00 minutes) in the study group. Comparisons of the two groups revealed a statistically significant difference (p = 0.002).ConclusionNasal mucociliary clearance time was significantly increased in patients with H pylori infection. The results suggest that H pylori infection may have an unfavourable effect on nasal mucociliary clearance.

Context Helicobacter pylori (H. pylori) has a worldwide distribution, but the prevalence of infection, virulence factors, and clinical presentation vary widely according to the studied population. In Brazil, a continental country composed of several ethnicities and cultural habits, the behavior of infection also appears to vary, as many other studies have shown. Objectives Describe the prevalence of infection with cagA-positive H. pylori strains in a group of children and adolescents who underwent esophagogastroduodenoscopy in Porto Alegre, Rio Grande do Sul. Methods Fifty-four gastric biopsy specimens of children and adolescents with H. pylori infection demonstrated by histology, urease test and molecular analysis were tested for the presence of cagA positive H. pylori strains by the polymerase chain reaction method. Results he prevalence of cagA-positive H. pylori was 29.6% (95% confidence interval, 18 to 43.6%). There were no statistically significant differences in clinical or demographic characteristics or in the endoscopic and histological features of patients infected with cagA-positive strains as compared with those infected by cagA-negative strains. Conclusions he study showed a low prevalence of infection with cagA-positive H. pylori strains among children and adolescents who underwent EGD in southern Brazil, in comparison to studies conducted with children from other regions of Brazil. There was no association between the presence of cagA-positive strains and more severe clinical presentations in the studied sample.

Abstract Background The current epidemiology of upper gastrointestinal bleeding (UGIB) in Thailand is poorly understood and the reported prevalence of Helicobacter pylori infection is outdated. Objectives To investigate the etiologies of UGIB and prevalence of H. pylori infection in Thailand, including its association with UGIB. Methods We retrieved information regarding patients attending the endoscopic unit of King Chulalongkorn Memorial Hospital from June 2007 to January 2013. A database search using keywords “upper gastrointestinal bleeding” and “iron deficiency” was used. From 4,454 diagnoses, after exclusion criteria, 3,488 patients (2,042 male (58.5%) and 1,446 female (41.5%); mean age 63.3 ± 15.94 years, range 13–103 years) were included. Results The three most common causes of UGIB were peptic ulcer (38.2%), nonulcer-mucosal lesions (23.4%), and esophageal-related causes (20.4%). The 5 year-incidence of H. pylori was 25%–30%. The overall prevalence was 27%. The prevalence of H. pylori infection was found to decrease with age from 43.8% at <40 years to 21.7% at >79 years old. H. pylori infection was significantly associated with duodenal and gastroduodenal ulcers. Cirrhosis and nonulcer-mucosal lesions were significantly unrelated to H. pylori infection. Patients with concurrent cirrhosis with peptic ulcer were found to be negative for H. pylori infection. Conclusion Peptic ulcer is the leading cause of UGIB in Thailand. However, its incidence is declining. Patients who presented to hospital with UGIB were older, compared with those a decade ago. H. pylori infection plays an important role in UGIB and its incidence was stable during the past 5 years.

Background. Peptic ulcer disease (PUD) remains one of the most prevalent gastrointestinal diseases and has been linked to Helicobacter pylori (H. pylori) infection. This condition may be suspected on clinical grounds, but diagnosis is established using upper gastrointestinal endoscopy. Aims. To determine the correlation between the endoscopic and pathological findings among suspected PUD patients who have been referred for diagnostic upper gastrointestinal endoscopy in National Hospital Abuja. Methods. This is a hospital-based prospective study conducted among suspected PUD patients at National Hospital Abuja over a one-year period. Clinical, endoscopic, and histological findings were ascertained and documented. Data obtained were analyzed using SPSS version 21.0. Tests of significance were done using the chi-square test and Student t -test at 95% confidence intervals. Results. One hundred and thirty-two patients were included in the study. The ages ranged from 15 to 87 years, mean age 43.30 ± 11.94 years. Seventy-seven (58.3%) patients had abnormal endoscopic findings, of whom 37 (28.0%) had PUD. Prevalence of H. pylori infection was 42.2% and was found in 81.1% of PUD patients. H. pylori was significantly associated with confirmed PUD ( p < 0.001 ) and abnormal endoscopic findings ( p < 0.001 ). No association was found between normal endoscopic findings and histological findings ( p = 0.924 ). Conclusion. There is a poor correlation between clinical and endoscopic diagnoses of PUD. H. pylori was found to be significantly associated with PUD and abnormal endoscopic findings. Endoscopic facilities should therefore be made available and accessible for proper PUD diagnosis. Empirical treatment of H. pylori in patients with diagnosed PUD is strongly recommended.

Background: Primary Open-Angle Glaucoma (POAG) the most common form of glaucoma is a neurodegenerative disease, which is the third most common cause of blindness worldwide. It is estimated that 60 million people in the world are affected by this disease and 8.4 million are bilaterally blind. Among the various factors that have been implicated in the pathophysiology of this disease is infection with Helicobacter pylori (HP), a Gram-negative bacterium that is commonly found in stomach and present in approximately one-half of the world’s population. Establishment of such a causal correlation will probably have important practical applications as the eradication of H. pylori might lead to developments in the treatment of glaucoma. Objectives: To investigate the association between Primary Open-Angle Glaucoma (POAG) and Helicobacter Pylori infection and to observe fluctuations in intra ocular pressure after Helicobacter Pylori infection eradication. Design: Duration based, prospective observational study. Participants: 50 patients with documented Primary Open-Angle Glaucoma (POAG) as case group and 50 non-glaucoma participants as control group. Methods: Upper gastrointestinal endoscopy was performed to evaluate macroscopic abnormalities, and gastric mucosal biopsy specimens were obtained for the presence of H. pylori infection tested by Rapid Urease Test (RUT). All subjects underwent detailed ocular examinations including visual acuity, slit-lamp examination, fundoscopy, intra-ocular pressure recording, gonioscopy, GHT to assess visual fields and OCT of optic nerve head. Results: In 90% of POAG patients of case group and in 68% of non-glaucoma participants of control group Helicobacter pylori infection was detected by RUT (P-Value=0.007). Conclusion: H. pylori infection is more frequent in glaucoma patients, perhaps more so in those of Indian ethnicity. It may play a role as a secondary aggravating factor or even may be the primary cause. The establishment of such a causal relationship will probably have important practical applications as the eradication of H. pylori might lead to developments in the treatment of glaucoma.

Abstract Background Helicobacter pylori (H. pylori) infection is the most important risk factor for gastritis and peptic ulcer. However, factors other than H. pylori are involved in its pathogenesis. In the current study, we aimed to compare the clinical manifestations and endoscopic and histopathological findings of patients with and without H. pylori infection. Methods In this cross-sectional study, 233 patients with dyspepsia, referred for endoscopy, were examined regarding the presence of H. pylori infection. During an endoscopic exam, 5 biopsy specimens were taken from the stomach. The criteria for the presence of H. pylori infection was the presence and identification of bacteria in pathology. Two groups of H. pylori-positive and H. pylori-negative patients were compared regarding their demographic, endoscopic, and pathological findings. Results Of 233 patients, 154 (66.1%) were non-smokers, 201 (86.3%) were not alcohol users, and 153 (65.7%) used tap water. The most common symptom, reported in 157 (67.4%) patients, was epigastric pain. There was a significant difference between patients with and without H. pylori infection in terms of the educational status, occupational status, family history of gastrointestinal cancer, and some gastrointestinal symptoms. Also, there was a significant relationship between the endoscopic and pathological findings of patients with H. pylori. Conclusions The results of the present study revealed that H. pylori infection was not associated with sex, alcohol consumption, or non-steroidal anti-inflammatory drug use. The role of H. pylori in the pathophysiology of peptic ulcer was clarified. Also, there was a significant difference in the endoscopic and pathological findings of patients with H. pylori.

We previously reported that 3-pentylcatechol (PC), a synthetic non-allergenic urushiol derivative, inhibited the growth of Helicobacter pylori in an in vitro assay using nutrient agar and broth. In this study, we aimed to investigate the in vivo antimicrobial activity of PC against H. pylori growing in the stomach mucous membrane. Four-week-old male C57BL/6 mice (n = 4) were orally inoculated with H. pylori Sydney Strain-1 (SS-1) for 8 weeks. Thereafter, the mice received PC (1, 5, and 15 mg/kg) and triple therapy (omeprazole, 0.7 mg/kg; metronidazole, 16.7 mg/kg; clarithromycin, 16.7 mg/kg, reference groups) once daily for 10 days. Infiltration of inflammatory cells in gastric tissue was greater in the H. pylori-infected group compared with the control group and lower in both the triple therapy- and PC-treated groups. In addition, upregulation of cytokine mRNA was reversed after infection, upon administration of triple therapy and PC. Interestingly, PC was more effective than triple therapy at all doses, even at 1/15th the dose of triple therapy. In addition, PC demonstrated synergism with triple therapy, even at low concentrations. The results suggest that PC may be more effective against H. pylori than established antibiotics.
