Recognizing nonerosive reflux disease (NERD) as a distinct presentation of gastroesophageal reflux disease (GERD) was one of the most important developments in the field of GERD in the last decade. Whilst the definition of NERD has not changed significantly over the years, the disorder accounts for the majority of the GERD patients and those who failed(More)
Gastro-oesophageal reflux disease (GORD or GERD) is a very common disorder, and advancement in drug development over the years has markedly improved disease management. Proton pump inhibitors (PPIs) remain the mainstay of treatment for GERD due to their profound and consistent inhibitory effect on acid secretion. However, PPIs do not reduce the number of(More)
SUMMARY Up to 30% of patients with hepatitis C virus (HCV) infection and normal serum alanine aminotransferase (NALT) have significant liver disease. Currently, many of these patients undergo a liver biopsy to guide therapeutic decisions. The BreathID continuous online (13)C-methacetin breath test (MBT) reflects hepatic microsomal function and correlates(More)
Patients with gastro-esophageal reflux disease (GERD) who are not responding to proton pump inhibitors (PPIs) given once daily are very common. These therapy-resistant patients have become the new face of GERD in clinical practice in the last decade. Upper endoscopy appears to have a limited diagnostic value. In contrast, esophageal impedance with pH(More)
BACKGROUND Little is known about the contribution of bile and acid reflux to night-time symptoms generation in patients who failed PPI treatment. AIM To compare the degree of night-time oesophageal acid and bile [by the surrogate duodenogastroesophageal reflux (DGER)] exposure between gastro-oesophageal reflux disease (GERD) patients who failed and those(More)
BACKGROUND Acute stress exacerbates heartburn in gastroesophageal reflux disease (GERD) patients by enhancing the perceptual responses to intraesophageal acid. The aim of the study was to determine if antireflux treatment can still alter stimulus response functions to acid in patients undergoing acute stress as compared with placebo. METHODS Symptomatic(More)
BACKGROUND  A potential relationship has been suggested between gastro-oesophageal reflux disease (GERD) and interstitial lung diseases (ILDs). AIM  To evaluate whether there is a causal relationship between GERD and different ILDs. METHODS  We conducted a systematic search of literature published between 1980 and 2010. After a review by two independent(More)
BACKGROUND There is a bidirectional relationship between gastroesophageal reflux disease (GERD) and sleep. It has been demonstrated that antireflux treatment can improve sleep quality in GERD patients with nighttime reflux. MATERIALS AND METHODS Patients with heartburn and/or regurgitation ≥3 times/week and insomnia for ≥3 months were included. Patients(More)
BACKGROUND Heartburn is commonly associated with the presence of acid in the oesophageal lumen. However, in patients with nonerosive reflux disease (NERD), the mechanism by which acid traverses the mucosa is not clear. We hypothesized that the luminal acid signal traverses the oesophageal epithelium in the form of the highly permeant gas CO(2) , which then(More)
