Filter by:The aim of the present study was to evaluate the effect of a 6-weeks treatment of a CE-marked combination oral formulation of hyaluronic acid with chondroitin sulphate and aluminium hydroxide (GERDOFF®), in addition to proton pump inhibitors (PPI) at the standard dose, versus PPI only, in patients with first diagnosed clinical presentation of extra-esophageal GERD symptoms. The investigators verified the reduction of symptoms frequency, using a Likert questionnaire, and severity, using the Reflux Symptom Index (RSI) questionnaire, to evaluate the proportion of Responders and Non-Responder patients in these two groups after 6 weeks of treatment, compared to baseline. Moreover investigators evaluated the persistence of effects of GERDOFF® + PPI treatment on extraesophageal symptoms, after a 12-weeks follow up, only in responder patients.
Our group recently studied the relationship between intra-gastric pressure (IGP) and reflux events after a meal, both in gastro-esophageal reflux disease (GERD) and in healthy volunteers (HV). Ingestion of a meal was accompanied by a drop in IGP, probably representing gastric accommodation (GA). However, the magnitude of this IGP drop varied, and was inversely correlated with the number of transient lower esophageal sphincter relaxations (TLESRs) and the number of reflux events, both in patients and in HV: a smaller meal-induced drop in IGP was associated with a higher rate of reflux events, and vice versa. These findings suggest that impaired GA is a trigger for reflux. Furthermore, impaired GA is a well-established mechanism underlying symptom generation in functional dyspepsia (FD). Hence, the investigators hypothesize that impaired GA is an important pathophysiological feature explaining the overlap between GERD and FD. To evaluate this hypothesis, the investigators will study the relationship between GA, TLESRs and reflux events in HV and in a group of GERD patients which will be categorized as pure GERD or GERD/FD overlap.
Recently the relationship between intragastric pressure (IGP) and reflux events after a meal was investigated, both in gastro-esophageal reflux disease (GERD) patients and in healthy volunteers. Ingestion of a meal was accompanied by a drop in IGP. However, the magnitude of this drop varied and was inversely correlated with the number of transient lower esophageal sphincter relaxations (TLESRs) and the number of reflux events, both in patients and in healthy volunteers: a smaller meal-induced drop in IGP was associated with a higher rate of reflux events and vice versa. This finding suggests that a smaller meal-induced drop may act as a trigger for reflux. It has been demonstrated that bitter administration leads to a smaller meal-induced drop. Therefore, bitter can be a dietary trigger for TLESRs facilitating the occurrence of symptoms of GERD. To evaluate this hypothesis, the researchers will study the relationship between bitter and the occurrence of TLESRs and reflux events in healthy volunteers. Additionally, it has been demonstrated that administering bitter also influences the concentration of motilin. Therefore, the research team will also measure the concentration of motilin to investigate whether changes in motilin concentrations can influence the number of TLESRs, via a change in gastric tone.
Citalopram is sometimes used in the treatment for gastro-esophageal reflux disease, however, there are no empirical data to support this. The investigators would like to know if citalopram has an effect on the lower esophageal sphincter pressure, transient lower esophageal sphincter relaxations and reflux episodes. The investigators will investigate this by performing high resolution impedance manometry in healthy volunteers before and after a solid meal. This will be compared to placebo, in a cross-over, randomized, double-blind condition.
The purpose of study is to confirm the efficacy of DWP14012 Xmg, Once daily, compared to esomeprazole 40mg in patients with erosive gastroesophageal reflux disease.
Investigator will identify a consecutive cohort of patients who have undergone a hiatal hernia repair and are at least 6 months post index procedure.
There is little evidence on the effect of a nickel-free diet on gastroesophageal reflux disease (GERD). We hope to determine if a nickel-free diet improves GERD symptoms in patients with a nickel allergy by having patients complete a questionnaire on their GERD symptoms before and after initiation of 8 weeks on a nickel-free diet.
The hypothesis of this study is that surgical techniques primarily designed for weight loss, ameliorates gastroesophageal reflux disease (GERD) in morbidly obese patients. Therefore the present study intends to evaluate such impact on patients submitted to two of the most common techniques available, the Roux-en-Y Gastric Bypass and Vertical Sleeve Gastrectomy.
460 patients who are scheduled for surgical treatment of gastroesophageal reflux disease (GERD) participate in the study following the usual preoperative Clinical routines (Medical history, endoscopy with biopsies, esophageal manometry with 24 hour pH (acidity) registration ). Patients are randomized to fundoplication according to Nissen or modified Toupet. Postoperatively, patients are monitored after 6 weeks 12, 36, 24 and 60 months.
This study plans to learn more about reflux associated laryngeal symptoms, and more efficient ways to diagnose and treat this condition.
