Background\Aim: Quadruple daily administration of proton-pump inhibitor (PPI) therapy achieves potent acid inhibition, and combined with amoxicillin, with its pharmacodynamic and pharmacokinetic characteristics, may be efficient for Helicobacter pylori eradication. We compared the efficacy of two optimized high-dose dual therapies with a bismuth-containing quadruple regimen for treating H. pylori infection. Rabeprazole dosages for H. pylori eradication were also evaluated. PATIENTS AND METHODS: Treatment-naive and H...

Objective The long-term use of proton pump inhibitors (PPIs) may induce adverse events in many organs, including the stomach. The chronic use of PPIs has been associated with the growth of fundic gland polyps (FGPs) and of gastric black spots. This study assessed the incidence of gastric lesions with cobblestone-like appearance in PPI users. Methods The clinical characteristics and endoscopic findings of patients who underwent upper gastrointestinal endoscopy after using PPIs for at least six months were analyzed...

This review article summarizes knowledge about metachronous gastric cancer (MGC) occurring after curative endoscopic resection (ER) of early gastric cancer (EGC), treatment outcomes of patients who developed MGC, and efficacy of Helicobacter pylori eradication to prevent MGC. The incidence of MGC following curative ER increases over time and is higher than in patients undergoing gastrectomy. Increasing age and multifocal EGC are independent risk factors for developing MGC. An MGC following curative ER is usually a small (<20 mm) and differentiated intramucosal cancer...

In current clinical practice, there is no optimal empirical therapy for Helicobacter pylori (H. pylori) infection and there is a progressive decrease in the efficiency of classical eradication therapy (ET) regimens. The variability in the efficiency of ET in a specific patient is largely due to the heterogeneous molecular genetic mechanisms underlying the resistance of the microorganism to the components of the treatment regimens. The basis of the mechanisms for antibiotic resistance in H. pylori is mainly the point mutations in some genes, which determine alterations in the mechanisms of action of drugs, such as clarithromycin (domain V of 23S rRNA), metronidazole (rdxA, frxA), amoxicillin (pbp1A), tetracycline (16S rRNA), and levofloxacin (gyrA)...

BACKGROUND: The rate of H. pylori resistance to different antibiotics is increasing and determines the selection of eradication therapy. The aim of this study was to determine the resistance patterns of H. pylori strains in our area. METHODS: Biopsies from gastric corpus for microbiological culture and antibiotic resistance were obtained in patients undergoing upper gastrointestinal endoscopy for dyspepsia. Selective Agar Pylori for isolation of the bacteria and Agar Mueller-Hinton supplemented with blood to test the sensitivity to antibiotics were used...

Dyspepsia is an umbrella term used to encompass a number of symptoms thought to originate from the upper gastrointestinal tract. These symptoms are relatively non-specific; not surprisingly, therefore, a myriad of conditions may present with any one or a combination of these symptoms. Therein lies the clinician's first challenge: detecting the minority who may have a potentially life-threatening disorder, such as gastric cancer, from a population whose symptoms are, for the most part, considered functional in origin...

Helicobacter pylori infection in children differs from that in adults, from the point of view of epidemiology, host response, clinical features, related diseases, and diagnosis, as well as treatment strategies. The prevalence of H. pylori infection, in both children and adults, is decreasing in the Western World as well as in some developing countries, which contrasts with the increase in childhood asthma and allergic diseases. Recurrent abdominal pain is not specific during H. pylori infection in children...

A substantial decrease in Helicobacter pylori-associated peptic ulcer disease has been observed during the last decades. Drug-related ulcers as well as idiopathic ulcers are becoming predominant and are more refractory to treatment; however, H. pylori infection still plays an important role in ulcer bleeding and recurrence after therapy. The effect of H. pylori eradication upon functional dyspepsia symptoms has been reviewed in this article and generally confirms the results of previous meta-analyses. Additional evidence suggests a lack of impact upon the quality of life, in spite of improvement in symptoms...

The huge variety of extragastric diseases linked to Helicobacter pylori infection is widely known, and new studies are conducted every year on this topic. Neurological disorders and metabolic syndrome are some of the main issues debated in the most recent literature. Articles on the association of H. pylori with skin diseases, inflammatory bowel diseases, immunologic impairment, kidney dysfunction, allergic asthma, and respiratory diseases have been published as well. In this perspective, eradication therapy for this infection could become a mandatory measure in prevention strategy...

In a retrospective study performed in California, U.S.A., ca. 3% of patients with gastric intestinal metaplasia (GIM) developed gastric cancer (GC) within a median time period of 4.6 years after diagnosis of GIM. This observation stresses the importance of targeted surveillance even in regions with a low GC prevalence. Patients with alcoholic liver disease as well as survivors of colorectal and lobular breast cancer were found to be at increased risk of secondary GC. A population-based Chinese study confirmed "serologic biopsy" as a useful screening tool for stratifying the individual risk of developing GC...

Cytomegalovirus (CMV) sometimes causes gastritis, especially in immunocompromised patients, but whether CMV gastritis promotes the development of gastric cancer is unknown. Here, we report a case of gastric cancer that developed in the presence of CMV gastritis, which had been present for at least 4 years and was refractory to treatment. An 80-year-old woman had noted epigastric discomfort and appetite loss. Esophagogastroduodenoscopy revealed a shallow geographical ulcer extending from the upper body to the pylorus...

A 37-year-old-woman was referred to our center after her uterine cervix health screening presented abnormal findings. We performed a biopsy of the uterine cervix to examine for cervical dysplasia, and diagnosed a diffuse large B-cell lymphoma transformed from mucosa-associated lymphoid tissue (MALT) lymphoma of the cervix. The patient presented with concurrent chlamydial cervicitis and received eradication therapy for Chlamydia trachomatis. Four months later, the CD20 positive abnormal lymphocyte disappeared and complete remission was achieved...

BACKGROUND: Helicobacter pylori (H. pylori) eradication is usually assessed using the 13C-urea breath test (UBT), anti-H. pylori antibody and the H. pylori stool antigen test. However, a few reports have used pepsinogen (PG), in particular, the percentage change in the PG I/II ratio. Here, we evaluated the usefulness of the percentage changes in serum PG I/II ratios for determining the success of eradication therapy for H. pylori. MATERIALS AND METHODS: In total, 650 patients received eradication therapy from October 2008 to March 2013 in our Cancer Institute Hospital...
