BACKGROUND: Current available treatments for Helicobacter pylori eradication are chosen according to local clarithromycin and metronidazole resistance prevalence. The aim of this study was to estimate, by means of molecular methods, both clarithromycin and metronidazole resistance in gastric mucosa from patients infected with H.pylori. METHODS: A total of 191 DNA samples were analyzed. DNA was purified from gastric mucosa obtained from patients who underwent an upper gastrointestinal endoscopy at an university hospital from Santiago, Chile, between 2011 and 2014...

BACKGROUND AND AIM: Infection by Helicobacter pylori is implicated in a wide range of upper gastrointestinal diseases. Owing to the rapid emergence of antibiotic-resistant strains of H. pylori, the development of novel treatment modalities for antibiotic-resistant H. pylori infection is a key priority. Blue light-emitting diodes (LED) may represent a unique option owing to their antimicrobial effect. In this study, we aimed to evaluate the anti-proliferative effect of blue LED against antibiotic-resistant H...

Helicobacter pylori (H. pylori) infection is one of the major causes of bleeding peptic ulcer disease, which is associated with serious complications; therefore, the eradication of H. pylori is essential to prevent these devastating complications. Post-treatment follow-up is crucial to guarantee the eradication of the organism and may be conducted via the urea breath test, the stool antigen test, or a gastric biopsy. Acute massive upper gastrointestinal (UGI) bleeding is one of the most common complications of peptic ulcer disease...

BACKGROUND: Increasing resistance of Helicobacter pylori (H. pylori) to antibiotics calls for constant re-evaluation of multidrug regimens that have been used to eradicate the infection. The aim of this study was to evaluate the current antibiotic susceptibility of H. pylori in an Icelandic cohort. METHODS: Patients referred for gastroscopy were recruited prospectively. Those found to have a positive rapid urease test were included in the study. Susceptibility testing was conducted by the Epsilometer test (E-test) method for ampicillin, clarithromycin, levofloxacin, metronidazole and tetracycline...

Chronic inflammation contributes to the development of various forms of cancer. The polyamine catabolic enzyme spermine oxidase (SMOX) is induced in chronic inflammatory conditions, including Helicobacter pylori-associated gastritis, where its production of hydrogen peroxide contributes to DNA damage and subsequent tumorigenesis. MicroRNA expression levels are also altered in inflammatory conditions; specifically, the tumor suppressor miR-124 becomes silenced by DNA methylation. We sought to determine if this repression of miR-124 is associated with elevated SMOX activity and concluded that miR-124 is indeed a negative regulator of SMOX...

Over three decades have passed since the discovery of Helicobacter pylori (H. pylori), and yet many questions about its treatment remain unanswered. For example, there is no certainty regarding continued use of current antibiotic therapy against H. pylori. The bad news is that even combined regimens are also unable to eradicate bacterial colonization. The worst problem with H. pylori chemotherapy is that even if we identify the most successful regimen, it cannot eliminate the risk of re-infection. This problem is further complicated by the fact that clinicians have no information as to whether probiotics are useful or not...

BACKGROUND: The prevalence of gastroesophageal reflux disease (GERD) has increased in Japan since the end of the 20th century due to changes in environmental factors, such as a decreased infection rate of Helicobacter pylori and increased ability of acid secretion in the Japanese population. In 2013, the Japanese health insurance system started to cover eradication treatment for all patients infected with H. pylori to prevent gastric cancer, suggesting we may soon be able to completely eradicate this infection in Japan...

BACKGROUND AND AIMS: Infection due to Helicobacter pylori causes many gastrointestinal diseases including peptic ulcers and gastric carcinoma. Their treatment and prevention depends on the successful eradication of H. pylori. However, even after a well-conducted treatment, H. pylori persists in about 10-30% of patients. Recurrent infections can correspond to relapse or to re-infection and require appropriate medical care. In this study, we explore retrospectively three clinical cases using molecular methods, and propose new guidelines for the diagnosis of recurrence...

BACKGROUND The eradication of Helicobacter pylori infection, commonly prevailing in the stomach, has been important since its introduction. Adequate preparations should be made in finding alternatives when faced with first-line treatment failures. Currently, ideal second-line treatments are indistinct and varied among countries as result of different antibiotic resistance patterns. We aimed to evaluate the safety and efficacy of a clarithromycin-containing bismuth-based quadruple regimen as a second-line treatment...

MicroRNAs (miRNAs) are small non-coding RNAs that function as endogenous silencers of target genes, previous studies have shown that miR-335 play an important role in suppressing metastasis and migration in human cancer including gastric cancer (GC). However, the mechanisms which result in aberrant expression of miR-335 in GC are still unknown. Recent studies have shown that the silencing of some miRNAs is associated with DNA hypermethylation. In this study, we find the promoter of miR-335 we embedded in CpG island by accessing to bioinformatics data and the low expression of miR-335 in 5 gastric cell lines can be restored by 5-aza-2'-deoxycytidine (5-Aza-dC) treatment...

BACKGROUND: We previously reported that eradication of Helicobacter pylori in our cohort of patients with peptic ulcer disease reduced their risk of developing gastric cancer to approximately one-third after a mean follow-up period of 3.4 years (up to 8.6 years). We have now followed these patients for a longer period. METHODS: A total of 1,222 consecutive patients with peptic ulcer diseases who completed more than 1-year follow-up after receiving H. pylori eradication therapy were followed with annual endoscopic surveillance for a mean of 9...

The clarithromycin-based triple therapy should not yet be prescribed as probabilistic first-line treatment in France. The sequential therapy should be recommended as first-line regimen. The empirical antibiotic therapy with a quadruple association PPI, tetracycline, metronidazole and bismuth is the most interesting alternative, particularly in patients allergic to beta-lactams or having previously received macrolides regardless of the indication. After the treatment, the control must be systematic, 4 weeks after stopping antibiotics and 15 days after stopping PPI...
