AIM To investigate the resistance of Helicobacter pylori (H. pylori) to ciprofloxacin (CIP), levofloxacin (LVX) and moxifloxacin (MOX) in the Beijing area and to elucidate the resistance mechanisms. METHODS Seventy-nine H. pylori clinical strains, isolated from patients who had undergone upper gastrointestinal endoscopy in Peking University First Hospital(More)
OBJECTIVE To investigate the prevalence of Helicobacter pylori (H. pylori) resistance to metronidazole, clarithromycin and amoxicillin in Beijing. METHODS H. pylori strains were cultured from the gastric biopsy samples obtained from 159 patients with upper abdominal symptoms by gastroendoscopy. Minimal inhibitory concentrations of antibiotics were(More)
According to a meta-analysis, H pylori and non-steroidal anti-inflammatory drugs (NSAID) independently and significantly increase the risk of gastroduodenal ulcer and ulcer bleeding. Their coincidence is frequent, demonstration of a possible relationship and consequent attitude is of important implications. But unfortunately, no consensus has been approved(More)
