“…Clinical studies have been performed for eradiation therapy of H. pylori gastritis and gastric MALT lymphoma over the last three decades. Guidelines for the diagnosis and management of H. pylori infection of the stomach were published and updated recently by the World Gastroenterology Organization, the American College of Gastroenterology, the Asian-Pacific Association of Gastroenterology and other professional organizations over the last decade (Table 3 ) [ 2 , 7 , 9 , 11 , 25 , 31 – 36 ]. The guideline protocols are also adapted to H. pylori eradication therapy in gastric MALT lymphoma.…”

Helicobacter pylori (H. pylori)-associated gastritis is one of the most common infectious diseases in the United States, China and worldwide. Gastric mucosa-associated tissue lymphoma (MALT lymphoma) is a rare mature B-cell neoplasm associated with H. pylori infection that is curable by antibiotics therapy alone. The pathological diagnosis of gastric MALT lymphoma can be reached by histological examination, immunohistochemical staining and B-cell clonality analysis. H. pylori eradication is the choice of therapy for early-stage gastric MALT lymphoma. High response rates and long-term survival have been reported in refractory and localized diseases treated with low-dose radiation therapy. Systemic chemotherapy is recommended for advanced-stage gastric MALT lymphoma and cases with large B-cell lymphoma transformation. Recent advances in the pathological diagnosis and management of gastric MALT lymphoma are reviewed in this article.

“…The researchers pointed out that hydro sanitary conditions influence the infection, and in developed countries, such as the United States and Canada, the percentage decreases to 30% and 40%, (22). The most vulnerable group is the infantile group, because the infection is transmitted by consuming contaminated food or water (23). According to the results obtained by Sanchez-Ceballos, (24), in Madrid, Spain in a population of 618 individuals, where only 418 were accepted for participation, the prevalence for H. pylori infection was 77.8%.…”

Background: This research addressed the topic of timely diagnosis of Helicobacter pylori that is currently a problem for public health in Ecuador and worldwide. The prevalence of the pathogen has increased in the last decade, especially due to its direct participation in gastric cancer generation. Objectives: The present investigation was carried out to detect H. pylori in human stool samples by antigenic screening and culture. Methods: The methodology used in this study was direct and indirect analysis of patients with H. pylori infection symptoms. Overall, 50 stool samples were collected (16 from males and 34 from females) and transferred immediately to the laboratory; patients were excluded due to causes such as contamination or insufficient amounts of sample for the analysis. From these samples, antigenic screening and culture in plates were carried out using the Brucella blood agar selective medium under controlled conditions. The two methods were analysed using the Kappa coefficient. Results: After antigenic screening analysis, 25 samples (50%) were positive for H. pylori with four false positives for both genders. The culture results showed that 19 samples (38%) were positive with 32 isolates characteristic for H. pylori. After agreement analysis, the kappa index was 0.28 (discrete). Conclusions:The detection rate by antigenic screening was higher than that obtained by culture, this is mainly due to the lack of viable cells and the difficulty of adapting adequate isolation techniques.

We aimed to evaluate the effectiveness and safety of bismuth-containing quadruple therapy plus postural change after dosing for Helicobacter pylori eradication in gastrectomized patients. We compared 76 gastric stump patients with H. pylori infection (GS group) with 50 non-gastrectomized H. pylori-positive patients who met the treatment indication (controls). The GS group was divided into GS group 1 and GS group 2. All groups were administered bismuth potassium citrate (220 mg), esomeprazole (20 mg), amoxicillin (1.0 g), and furazolidone (100 mg) twice daily for 14 days. GS group 1 maintained a left lateral horizontal position for 30 min after dosing. H. pylori was detected using rapid urease testing and histologic examination of gastric mucosa before and 3 months after therapy. Mucosal histologic manifestations were evaluated using visual analog scales of the updated Sydney System. GS group 1 had a higher prevalence of eradication than the GS group 2 (intention-to-treat [ITT]: P=0.025; per-protocol [PP]: P=0.030), and the control group had a similar prevalence. GS group 2 had a lower prevalence of eradication than controls (ITT: P=0.006; PP: P=0.626). Scores for chronic inflammation and activity declined significantly (P<0.001) 3 months after treatment, whereas those for atrophy and intestinal metaplasia showed no significant change. Prevalence of adverse reactions was similar among groups during therapy (P=0.939). A bismuth-containing quadruple therapy regimen plus postural change after dosing appears to be a relatively safe, effective, economical, and practical method for H. pylori eradication in gastrectomized patients.
