BACKGROUND/AIMS Impedance-pH monitoring allows detailed characterization of gastroesophageal reflux and esophageal activity associated with reflux. We assessed the characteristics of nocturnal reflux and esophageal activity preceding and following reflux. METHODS Impedance-pH tracings from 11 healthy subjects and 76 patients with gastroesophageal reflux disease off acid-suppressive therapy we...
BACKGROUND/AIMS Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. METHODS We retrospectively reviewed the impedance-pH data in patien...
BACKGROUND AND AIM The reason that some reflux episodes evoke symptoms is poorly understood, therefore the aim of this study is to assess the determinants of reflux perception in patients with non-erosive reflux disease (NERD) on proton pump inhibitor (PPI) therapy. METHODS Ten NERD patients with persistent symptoms, despite double-dose PPI therapy, were included in this study. All patients h...
background gastroesophageal reflux disease is a common, chronic disease worldwide. the weekly prevalence of reflux in developed countries is 10% to 48%. it has previously been reported as 5% in asian countries, but new reports show a higher level in both asian and arab countries. in iran, reflux has increased over the last two decades. there are few studies concerning the prevalence of reflux i...
Non-erosive reflux disease (NERD) is the most common presentation of gastroesophageal reflux disease. Although acid reflux is the most important cause of symptom generation in NERD patients, non-acid reflux is also associated with reflux symptoms. The temporal relation between symptoms and reflux episodes is of importance in evaluating the results of combined pH-impedance monitoring in NERD pat...
Objective- Trigonella foenum graecum, (Fenugreek) has anti-inflammation, antiseptic and antidiabetic activities in traditional medicine. This study was performed to investigate the protection effects of Fenugreek seed extract on the experimental reflux esophigitis (RE) in rats. Design- experimental study. Animals- 24 male Wistar albino rats. Procedures- Rats were randomly allocated into 4 group...
The mechanical force relationships that distinguish normal from chronic reflux at sphincter opening are poorly understood and difficult to measure in vivo. Our aim was to apply physics-based computer simulations to determine mechanical pathogenesis of gastroesophageal reflux. A mathematical model of the gastroesophageal segment (GES) was developed, incorporating the primary anatomical and physi...
Nocturnal gastro-oesophageal reflux may be important in the pathogenesis of reflux oesophagitis. This study aimed to determine whether: (1) gastro-oesophageal reflux occurs during sleep in patients with reflux oesophagitis and, if so, to explore the mechanism, and (2) the sleep pattern of patients with oesophagitis is different from that of control subjects. After a standard evening meal, simul...
The aim of this study was to compare acid reflux in 16 patients with uncomplicated Barrett's oesophagus with 37 patients with reflux oesophagitis and 10 control subjects of comparable age. All patients had 24 hour ambulatory pH monitoring within one week of endoscopy. The controls differed significantly from the other groups in all indices of reflux but there was no difference between the Barre...
We investigated comparison according to reflux esophagitis and non-erosive reflux disease about "daily" symptom improvement for proton pump inhibitor treatment. We enrolled 57 reflux esophagitis and 90 non-erosive reflux disease patients. They took rabeprazole 10 mg/day for 28 days and completed "daily" in the Frequency Scale for the Symptoms of GERD from baseline until day 14, and after 28 day...
