Observational Non-interventional Study on the Use of International GerdQ Questionnaire for the Diagnosis of Gastroesophageal Reflux Disease in the Russian Practice
There are three main directions for use GerdQ in practice. First of all, GerdQ can be used to diagnose GERD with an accuracy comparable to the accuracy of diagnosis of GERD by the specialist (gastroenterologist). Using GerdQ can evaluate the impact of disease on the patient's life and help in choosing treatment of GERD, as well as direct assessment of treatment efficacy. In connection with mentioned above, this study is devoted to the estimation of possibility to use GerdQ in routine practice of Russian physicians.

Effect Of Azithromycin On Oesophageal Function In Patients With Dysphagia Or Gastro-Oesophageal Reflux Associated With Frequent Oesophageal Hypomotility
Patients with difficulty in swallowing (dysphagia) or with reflux disease are frequently found to suffer from oesophageal hypomotility (weak contractions). Oesophageal motility is currently measured using high-resolution manometry (HRM). This technique has a 36 pressure sensors on a plastic tube to record the pressure in side the oesophagus. Several pharmaceutical agents (prokinetics) can stimulate oesophageal motility. However, use of prokinetics in patients with oesophageal hypomotility led to disappointing results. An explanation for these disappointing results is that inappropriate patients were targeted. The appropriate patient would be the one who still have some viable muscle in the oesophagus that can respond to pharmacological stimuli. In the process of developing treatment strategies in patients with oesophageal hypomotility, testing the preserved capacity of oesophageal muscles could be useful to predict the response of these patients to prokinetic drugs. The following tests have the potential to reveal the preserved capacity of the oesophageal muscle to respond to stronger/medicinal stimuli. 1. - Multiple rapid swallowing (MRS) of 5ml water boluses stimulates oesophagus. A normal response to MRS requires on the one hand integrity of neural mechanisms and on the other hand a functional oesophageal muscle. 2. - External abdominal compression can increase the resistance to bolus transport via oesophagus. The normal oesophagus produces contractions of higher amplitude and duration in order to maintain a normal bolus transit. 3. - Swallowing bread boluses require stronger oesophageal contractions for a successful bolus transit. The purpose of the proposed project is to firstly assess the effect of Azithromycin on oesophageal hypomotility and secondly to evaluate the predictive values of the stimulation techniques in predicting the likelihood the positive response to drug therapy.

The Clinical Significance of Acid Rebound: Symptoms of Reflux After PPI Treatment in Patients With Functional Dyspepsia
Proton pump inhibitors (PPI) have been shown to cause acid reflux related symptoms at withdrawal in healthy volunteers, a phenomenon known as Rebound Acid Hyper Secretion. Whether this also applies for patients with dyspeptic symptoms but without true reflux disease (functional dyspepsia) treated with PPI is unknown. If this is the case, it could lead to an unfortunate long term use of PPI, since the acid rebound renders withdrawal too difficult. This is a single centre, randomized, double-blinded, placebo-controlled cross over study. Study period is 12 weeks per study subject. Study subjects are referred to the study from General Practitioner (GP) and the gastroenterology department or endoscopy clinic of the investigational centre. The study population consists of patients who seek their GP because of dyspepsia without alert signs, and whom the GP may consider starting on PPI. Out patients referred to the gastroenterology department or endoscopy clinic of the investigational centre because of dyspepsia without specific exclusion criteria are also invited to participate. Baseline interview, upper endoscopy and pH monitoring are performed one week before inclusion to exclude patients with GERD. Helicobacter Pylori (Hp.) status is assessed by Helicobacter Urease Test (HUT). Hp. positive subjects without ulcus are not excluded. Patients with a positive pH monitoring will not be included in the analysis regarding the primary endpoint (Development of GERD) but will be included in the analysis regarding one of the secondary endpoints (Effect of PPI on Functional Dyspepsia). Study subjects are randomized to either pantoprazol followed by cross over to placebo or to placebo. Escape medication in the form of Gaviscon can be used on demand. Internet based questionnaires are answered weekly. Questionnaires consist of the Gastrointestinal Symptom rating Scale (GSRS) in combination with items assessing postprandial fullness and items assessing the Montreal Criteria for Gastro Esophageal Reflux Disease (GERD). Compliance to protocol is assessed at hospital visits every fourth week. At the end of study endoscopy and pH monitoring are repeated.

Gradual Cessation of Proton Pump Inhibitor (PPI) Treatment May Prevent Rebound Acid Secretion in Dyspeptic and Reflux Patients, Measured by the Alkaline Tide Method.
Gastro esophageal reflux disease and ulcer related or non-ulcer dyspepsia, attacks 20% of the Western population. These millions of patients are treated continuously with PPI for different periods, many for many years. Recently, rebound acid hypersecretion was recognized as a major clinical event after cessation of PPI therapy. Sustained hypergastrinemia due to daily PPI therapy causes increased acid-secretory capacity that appears when the drug is stopped. The transient increase in blood and urinary pH following gastric secretion has been termed the alkaline tide phenomenon. Carbonic acid, formed in the presence of the enzyme carbonic anhydrase, neutralizes intracellular hydroxyl ions produced as a result of luminal acid secretion. The bicarbonate generated is removed from the cell via the baso-lateral chloride bicarbonate exchanger. The investigators have shown in several studies that this phenomenon parallels acid secretion. Thus, stimulation of acid secretion with test meal increased base excess maximally after 45 minutes and these changes parallel peak acid output measured in gastric aspirate. The investigators hypothesize that gradual step down cessation of PPI will prevent this clinical relevant event. By measuring alkaline tide after PPI cessation the investigators may prove this hypothesis.

Comparing Omeprazole With Fluoxetine for Treatment of Non Erosive Reflux Disease and Its Subgroups: a Double-blind Placebo-controlled Clinical Trial
Gastro-esophageal reflux disease (GERD) is highly prevalent, affecting up to 20% of the adult population in North America. Up to 70% of GERD patients have non-erosive reflux disease (NERD), a term used to describe symptoms suggestive of GERD in patients with no endoscopic evidence of erosive esophagitis. NERD represents a heterogeneous group of patients whom are sub classified according to 24 hours-PH monitoring results and also symptom-acid association analysis(Symptom Index,SI). Treatment of NERD can be a challenge for clinicians. According to the many studies , the pooled rate for symptomatic response after a period of proton pomp inhibitor(PPIs)therapy as the most frequently used drug, in NERD patients is lower than for erosive esophagitis patients. It is also shown that acid exposure is much lower in NERD patients than those with erosive esophagitis and NERD patients are less likely to exhibit a strong association between heartburn symptoms and acid reflux events than patients with erosive oesophagitis. Furthermore, beside the high economic burden, there are concerns about the adverse effects of long time administration of PPIs. Several hypothesis has been proposed to describe low response rate of NERD patients to PPIs. One of the most acceptable theories is that patients with anxiety or depression and psychological problems are at an increased risk of developing reflux symptoms. On the other hand, pain modulators such as sertraline, a selective serotonin reuptake inhibitor(SSRI), and other antidepressants have been shown to improve symptoms in patients with functional gastrointestinal disorders like non cardiac chest pain. According to the above-mentioned tips, the investigators hypothesize that antidepressants like fluoxetine, as an SSRI, may have beneficial effects in improving symptoms of NERD patients. The purpose of this study is to compare the effect of omeprazole with fluoxetine and placebo for treatment of NERD patients and its subgroups who all experience reflux symptoms and have normal endoscopic findings.

A Cross-sectional Study on the Prevalence and Extraesophageal Symptoms of GERD in Patients With Upper GI Symptoms, Visiting the Outpatient Departments of Peripheral Hospitals in Greece. The 'GERDQ-XS' Study
The present study has been designed to provide current data on GERD prevalence in several regional areas of Greece outside the two major urban centres (Athens and Thessaloniki), to measure the treatment response in GERD patients, and to assess the correlations between the two methods of diagnosing GERD, i.e. reporting of symptoms by the patient to the physician and completion of the GerdQ questionnaire by the patient. Additionally, this study aims to provide data on the prevalence of extraesophageal symptoms in GERD patients in Greece. The XQS questionnaire will be applied for the identification of these patients and the assessment of the extraesophageal disease burden (frequency and intensity/severity). Finally, an association between the GerdQ and XQS scores will be attempted.
