OBJECTIVES Sequential therapy appears to achieve a higher Helicobacter pylori eradication rate than triple therapy. We assessed the efficacy and tolerability of modified sequential therapy containing levofloxacin and high-dose esomeprazole in second-line therapy. METHODS Patients who failed first-line triple therapy with clarithromycin, amoxicillin and a proton pump inhibitor were eligible in...

BACKGROUND Gastroesophageal reflux is common among patients with asthma but often causes mild or no symptoms. It is not known whether treatment of gastroesophageal reflux with proton-pump inhibitors in patients who have poorly controlled asthma without symptoms of gastroesophageal reflux can substantially improve asthma control. METHODS In a parallel-group, double-blind trial, we randomly ass...

Background/Aims Anti-reflux barrier dysfunction is one of the primary mechanisms in gastroesophageal reflux disease (GERD) pathogenesis. The esophagogastric junction contractile integral (EGJ-CI) is a new metric adopted to evaluate the EGJ contractility, which implies the antireflux barrier function. The aim of the current study was to validate this new metric in patients with GERD and its corr...
