BACKGROUND Several large clinical trials and meta-analyses have shown about 20% failure to eradicate Helicobacter pylori (H.pylori), necessitating investigations for second-line treatments. The aim of this study was to evaluate the effects of clarithromycin-containing quadruple regimen after nitroimidazole-containing quadruple therapy failure. METHODS Thirty two patients who had failed 10-day H...

The pathogenesis, incidence, complication rates, response to acid suppression and Helicobacter pylori (H. pylori) eradication therapy in peptic ulcer associated with chronic disease such as liver cirrhosis, chronic renal failure, diabetes mellitus, and critically ill conditions are different from those with general population, so that the management strategies also should be differentiated. The...

background: in developing countries primary antibiotic-resistance and poor compliance are the main causes of helicobacter pylori (hp) eradication failure of standard regimens. aim: to investigate eradication rate, patient's compliance and tolerability of a 1-wk azithromycin based quaruple therapy versus the 2-wk conventional therapy. materials and methods: a total of 129 hp-positive patients we...

GENBANK, THE PUBLIC REPOSITORY FOR nucleotide and protein sequences, is a critical resource for molecular biology, evolutionary biology, and ecology. While some attention has been drawn to sequence errors (1), common annotation errors also reduce the value of this database. In fact, for organisms such as fungi, which are notoriously difficult to identify, up to 20% of DNA sequence records may h...

Helicobacter pylori (H. pylori) infection is the main cause of gastritis, peptic ulcer, gastric cancer and MALTlymphoma. H. pylori eradication has been shown to have a prophylactic effect against gastric cancer. However, the most challenging point in eradicating H. pylori is the antibiotic resistance. In the United Arab Emirates, eradication of H. pylori is based on a triple therapy regimen com...

House mice (Mus musculus) were introduced to New Zealand accidentally in 1824 following the stranding of an Australian ship. Phylogeographic analyses have revealed many subsequent introductions from diverse sources. Mice have significant negative impacts on native ecosystems in New Zealand and elsewhere. This makes their eradication a desirable conservation outcome, yet a large proportion of mo...

BACKGROUND Increasing resistance to clarithromycin and nitroimidazole is the main cause of failure in the Helicobacter pylori eradication. The ideal retreatment regimen remains unclear, especially in developing countries, where the infection presents high prevalence and resistance to antibiotics. The study aimed at determining the efficacy, compliance and adverse effects of a regimen that inclu...
