There is growing concern about <em>Helicobacter pylori</em> (<em>H. pylori</em>) resistance strains being the main agent contributing to eradication failure. In this study we evaluated the prevalence and antimicrobial susceptibility trends of <em>H. pylori</em> over a period of time. Over a period of seven years a total of 384 biopsy specimens were sent to the microbiology department and evaluated for culturing <em>H. pylori</em> and assess its susceptibility. Biopsy specimens that cultured and where bacterial susceptibility was determined were regarded as <em>H. pylori</em> positive, and specimens that failed to culture were considered <em>H. pylori</em> negative. A total of 221 patients with <em>H. pylori</em> positive were assessed and antimicrobial susceptibility was determined. The overall prevalence of <em>H. pylori</em> infections among Saudis undergoing upper gastrointestinal endoscopy, with indicated specimens, was 57.6%. Antimicrobial susceptibility was evaluated; overall clarithromycin resistance was found to be 4.5% and metronidazole resistance 52.5%. The number of clarithromycin resistant strains has increased significantly from 2.5% in 2008 to 10% in 2014 (PH. pylori infection is very common among Saudi patients with peptic ulcer disease. Resistance of <em>H. pylori</em> against clarithromycin and metronidazole has increased significantly over the seven-year period. This suggests a need to monitor the annual antimicrobial susceptibility pattern.

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 & Aims: Human genetic polymorphism has been reported in the susceptibility and clinical development of infection. In this regard, this study aimed to investigate the link between Vitamin D Receptor (VDR) gene polymorphism and H. pylori infection. Materials and Methods: This cross-sectional study was conducted on 224 adult patients with upper gastrointestinal symptoms who underwent an upper gastrointestinal endoscopy between July 2017 and May 2019 in two major university hospitals. All patients were evaluated for helicobacter pylori infection. Two gastric antral biopsy specimens were taken from each patient. One of those Biopsy specimens was evaluated for histopathology examination and the other one was immersed in a saline solution ready for genomic DNA extraction. Results: There were statistically significant differences between different genotypes of VDR rs7975232 polymorphism between H. pylori infected and non-infected groups (CC was higher in H. pylori negative and AC and AA were the most common in H. pylori positive group). There were statistical differences between different genotypes of VDR rs2228570 between H. pylori infected and non-infected groups (TT was higher in H. pylori negative and CT and CC were the most common in H. pylori positive group). Regarding VDR rs 7975232 gene polymorphisms; the (A) allele was significantly higher H. pylori infected, while (C) allele was significantly higher in uninfected patients. Regarding VDR rs 2228570 gene polymorphisms; the (C) allele was significantly higher H. pylori infected, while (T) allele was significantly higher in uninfected patients. Conclusion: There is a possible association between the FokI and Apal VDR polymorphism and H. pylori infection.

Abstract Introduction: Treatment for Helicobacter pylori (H. pylori) infection is recommended in transplant candidates due to the association between this infection and gastrointestinal disorders, which could significantly increase morbidity after renal transplantation with the use of immunosuppression. The objective of this study was to analyze the rate of eradication of H. pylori after antimicrobial treatment in chronic kidney disease patients who are candidates for kidney transplantation. Methods: A multicenter prospective cohort study was conducted. All adult chronic kidney disease patients seen at our institution were included. In the pre-transplantation evaluation, 83 patients underwent an upper gastrointestinal endoscopy with 2 diagnostic methods to detect H. pylori: histology and the rapid urease test. In total, 33 patients with H. pylori infection received treatment with 20 mg omeprazole, 500 mg amoxicillin, and 500 mg clarithromycin once daily for 14 days. Another upper gastrointestinal endoscopy was performed 8 to 12 weeks after the end of treatment to check for healing. Results: The study showed a prevalence of H. pylori in 51 (61.4%) patients. Histology was positive in 50 (98%) patients and the rapid urease test was positive in 31 (60.8%). The infection eradication rate was 48.5% (16 patients). Conclusions: There was a high prevalence rate of H. pylori and a low eradication rate after the long-term antimicrobial triple scheme used. The association of the rapid urease test with gastric mucosa histology did not increase the detection rate of H. pylori.

Background. Helicobacter pylori (H. pylori) is a common and universally distributed bacterial infection. However, in children, active gastritis and ulcer are rarely seen. Objectives. The aims of this study were to establish the prevalence of H. pylori infection and to compare the clinical, endoscopic, and histopathological findings between infected and noninfected pediatric patients at Makassed General Hospital. Methods. Patients aged between 1 month and 17 years who underwent upper gastrointestinal endoscopy from January 2011 to January 2017 were included. The diagnosis of H. pylori was confirmed by a CLO test and/or its presence on biopsy specimens. Demographic data, clinical characteristics, endoscopic and histopathological findings, and gastritis score were recorded retrospectively. Results. During the study period, 651 children underwent upper gastrointestinal endoscopy. The main indication was abdominal pain (61%). The prevalence of H. pylori infection was 16.5%. The infection was most commonly seen among children aged between 6 and 10 years (43%). A large number of family members were associated with increased risk of infection (4.8±1.5 versus 5.2±1.8; p<0.05). Epigastric pain was more associated with H. pylori (61.3% versus 14.6% in noninfected patients; p<0.05). Nodular gastritis was commonly seen in infected patients (41.5% vs. 7.9%; p<0.05). Mild and moderate gastritis was seen more in infected versus noninfected patients (mild: 53.8% vs. 14%; moderate: 27.4% vs. 2.4%, respectively). Conclusion. Although epigastric pain was associated with H. pylori, other diagnoses should be considered since the infection are rarely symptomatic in children. Antral nodularity was associated with H. pylori infection; however, its absence does not preclude the diagnosis.

Background: Helicobacter pylori infection is widely prevalent in the world especially in the developing countries. The common clinical presentation of this disease includes peptic and duodenal ulcer. A major post-infection complication of this disease is gastric carcinoma. The scope of this study was to determine the prevalence of active H. pylori infection in the local population by retrospective review of patient records, which can give a better picture of the current situation and estimate the at-risk population of gastric carcinoma. Objective of the study was to determine the prevalence of H. pylori infection in biopsy specimens obtained from upper gastrointestinal endoscopy performed in dyspeptic patients in a tertiary-care hospital.Methods: The study was performed as a retrospective review of biopsy reports of 262 dyspeptic patients with previously unknown H. pylori status who underwent upper gastrointestinal endoscopy during the months of January 2018 to May 2018. Biopsy obtained from stomach was evaluated for the presence of H. pylori infection by Rapid Urease Test (RUT) or histopathological examination.Results: The prevalence of H. pylori infection in dyspeptic patients obtained from the above study was 44.7% and was found to be more common in males compared to females.Conclusions: H. pylori is a risk factor for gastric carcinoma. Determining the prevalence with early identification of active infections results in better treatment and post infection monitoring for malignancy.

Russell body gastritis is an extremely rare gastritis characterized by abundant infiltration of plasma cells with Russell body and eccentric nuclei, known as Mott cells. An 81-year-old Japanese woman with Helicobacter pylori and hepatitis C virus infection complaining of abdominal discomfort underwent upper gastrointestinal endoscopy, which detected an elevated lesion 2 cm in diameter at the anterior wall of the gastric body. A histological examination of the lesion revealed the infiltration of numerous Mott cells with an abundant eosinophilic crystal structure and eccentric nuclei in the lamina propria, resulting in a pathological diagnosis of Russell body gastritis. Endoscopic submucosal dissection (ESD) was performed subsequently. The histological findings of the resected specimen were compatible with those of Russell body gastritis. Upper gastrointestinal endoscopy performed 2 months after endoscopic submucosal dissection revealed the presence of new multiple flat elevated lesions in the antrum up to 1 cm in diameter, distant from the site of endoscopic submucosal dissection. A histological examination revealed a few Mott cells in the biopsy specimens taken from the new lesions. In turn, H. pylori eradication therapy was performed 1 month after the detection of the new lesions. One year after the eradication therapy, follow-up upper gastrointestinal endoscopy revealed that multiple lesions had almost disappeared, and the histological examination of the gastric biopsy specimens confirmed the disappearance of Mott cells. We herein report a case of Russell body gastritis in which multifocal lesions were observed after endoscopic submucosal dissection, and which was subsequently treated by H. pylori eradication therapy.

BACKGROUND/OBJECTIVES: As recently as 40 years ago, a decline in the incidence of peptic ulcers was observed. The discovery of Helicobacter pylori had a further major impact on the incidence of ulcer disease. Our aim was to evaluate the trends in the incidence and bleeding complications of ulcer disease in the Netherlands.METHODS: From a computerized endoscopy database of a district hospital, the data of all patients who underwent upper gastrointestinal endoscopy from 1996 to 2005 were analyzed. The incidence of duodenal and gastric ulcers, with and without complications, were compared over time.RESULTS: Overall, 20,006 upper gastrointestinal endoscopies were performed. Duodenal ulcers were diagnosed in 696 (3.5%) cases, with signs of bleeding in 158 (22.7%). Forty-five (6.5%) of these ulcers were classified as Forrest I and 113 (16.2%) as Forrest II. Gastric ulcers were diagnosed in 487 cases (2.4%), with signs of bleeding in 60 (12.3%). A Forrest 1 designation was diagnosed in 19 patients (3.9%) and Forrest 2 in 41 patients (8.4%). The incidence of gastric ulcers was stable over time, while the incidence of duodenal ulcers declined.CONCLUSIONS: The incidence of duodenal ulcer disease in the Dutch population is steadily decreasing over time. Test and treatment regimens for H pylori have possibly contributed to this decline. With a further decline in the prevalence of H pylori, the incidence of gastric ulcers is likely to exceed the incidence of duodenal ulcers in the very near future, revisiting a similar situation that was present at the beginning of the previous century.
