Development of a Novel Disease-Specific Quality of Life Questionnaire for Gastroesophageal Reflux...
Gastroesophageal Reflux DiseaseA questionnaire composed of items addressing psychological, emotional and social aspects of GERD is developed for Chinese population. We plan to conduct a validation study on this novel disease-specific quality of life (QoL) instrument. This study aims to evaluate various indicators of validity and reliability, which include criterion validity, test-retest reliability, responsiveness, internal consistency reliability and discriminant validity. After initial pilot testing of face validity and content validity, two hundred GERD patients from the gastroenterology and ulcer clinics of cluster NTE hospitals will be invited to complete a revised 18-item version of GERD-QOL questionnaire. The data from GERD QOL will be evaluated using exploratory factor analysis to identify appropriate items and domains and the internal consistency of the domains will be determined and further refinement of questionnaire will follow. 100 GERD patients will complete GERD-QOL, SF-36 health survey and the visual analog scale (VAS) questionnaire for criterion validation. 100 GERD patients with stable symptom profile will repeat GERD QOL two weeks after the first administration for evaluation of test-retest reliability. Another 26 patients who are receiving maintenance acid suppressive therapy and in remission of symptom will be recruited as controls for comparison with active reflux patients. The ability to distinguish active patients from controls in remission is known as discriminant validity.
Gastroesophageal Reflux Disease (GERD) Among ICU Survivors
Gastroesophageal Reflux DiseaseCritically IllGastro-esophageal reflux disease (GERD) is a condition characterized by reflux of stomach contents causing troublesome symptoms and complications. Typical symptoms include heart burn (a retrosternal burning sensation), regurgitation (perception of flow of refluxed stomach content into the mouth or hypopharynx) and chest pain. As per recently published global guidelines (2017) by World Gastroenterology Organisation (WGO), the presence of heartburn and/or regurgitation symptoms 2 or more times a week is suggestive of GERD. Global burden of GERD in general population is approximately 1.03 billion, the prevalence of GERD varies geographically, with the highest prevalence of 19.55% in North America while in Asia, the estimated rate is 12.92%. However the data regarding the prevalence of GERD in intensive care unit (ICU) population is not yet established; which is expected higher after recovery from their current acute illness. In a healthy individual, several factors contribute to the prevention of reflux and to minimizing esophageal acid exposure: lower esophageal sphincter (LES) pressure, the diaphragmatic crura, gravity, esophageal peristalsis, salivary bicarbonate and the integrity of esophageal epithelium. But in critically ill these factors are compromised leading to high incidence of GERD. Interventions commonly used in managing critically ill patients such as sedation, presence of an endotracheal tube, mechanical ventilation, enteral tube feedings, positioning, and medications, along with specific patient characteristics and comorbid conditions contribute to an increased risk for GERD in this population. GERD results in various symptoms which has impact on quality of life. Various reliable and validated generic and disease specific instruments are available to measure symptom severity of the disease. In the present study, among GERD patients, commonly and freely available GERD-Health-related quality of life (GERD-HRQL) score will be used which is a disease-specific instrument. This observational study will screen and enroll adult patients who survived at the time of ICU discharge.
Observational Study (This Means That no Drug is Tested) in Patients Suffering of Gastroesophageal...
Gastroesophageal Reflux DiseaseGastro-oesophageal Reflux3 moreThe purpose of this observational study (this means that no drug is being tested in this study) is to obtain updated and detailed information about the Gastroesophageal Reflux Disease (GERD) specificities in European patients. The information about patients suffering from typical GERD symptoms will be collected in order to establish a classification of adult patients profile based on the characteristics of GERD symptoms. This study will only involve data collection about the disease. The treatment will not be affected by the study.
Pharmacogenetic Testing in Children With Persistent Gastroesophageal Reflux Disease
Gastroesophageal RefluxThis study will use a 22 gene pharmacogenomics panel on 30 children with persistent Gastroesophageal Reflux Disease (GERD) who have not responded to therapy.
Biology in Patients With Reflux Esophagitis
GERDGERD is a common condition in the western world. In most cases, the diagnostic is established by good response to empiric proton pump inhibitor (PPI) therapy. When the patient symptoms are refractory to therapy, multiple invasive tests are available. The results of those tests (EGD, manometry, Ph monitoring and impedance) are clues that the physician use together to establish the diagnostic. No test however can be use alone because of their poor specificity and sensitivity. Recently, microscopy has been used to detect dilated intercellular space in between distal esophageal cells tissue; unfortunately this marker again failed to diagnose GERD. In search of more sensitive and specific markers of GERD, we propose to assess if acid exposure affects: 1) gene and proteins expression in the esophageal/post-cricoid area tissue; and 2) local impedance of the mucosa. The secondary aim of this proposal is to determine if correlation exists between the two approaches.
A Cross-sectional Study on the Prevalence and Extraesophageal Symptoms of Gastroesophageal Reflux...
Gastroesophageal Reflux DiseaseThe 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.
Relationship and Pathophysiology of Gastroesophageal Reflux and Dental/Periodontal Disease
Gastroesophageal RefluxDental ErosionThis study investigates the prevalence and pathophysiology of dental and periodontal involvement in pediatric patients with symptomatic or asymptomatic gastroesophageal reflux (GER) or gastroesophageal reflux disease (GERD). Primary objectives are to compare the prevalence of oral disease in children with and without a diagnosis or symptoms/signs of GERD in a cross-sectional study. Secondary objectives are to examine factors that might lead to the pathogenesis of the dental and periodontal lesions observed in this group of subjects. The primary hypothesis is to prove that children aged 10-18 years diagnosed with or having symptoms or signs of GERD have a significantly higher amount of dental erosions in comparison to a matched control group. Secondary hypotheses are that children aged 10 - 18 years diagnosed with or having signs of GER have higher DMFS (Decayed, Missing, Filled permanent tooth Surfaces) rates, higher SBI (Sulcus Bleeding Index) rates, worse Periodontal status, and lower saliva buffering capacity.

Waist Circumference Versus Body Mass Index to Predict Severity of Gastroesophageal Reflux Disease...
Gastroesophageal Reflux DiseaseObesityGastroesophageal reflux disease (GERD) is a common and important disorder. Previous studies have demonstrated the association of obesity with GERD, and now obesity is regarded as a risk factor for GERD. Moreover, body mass index (BMI), an indicator of general obesity, correlates with severity of symptoms and degree of erosive esophagitis. Waist circumference, an indicator of abdominal obesity, has stronger correlation with intra-abdominal pressure and low-grade inflammatory state when compared with BMI. Nevertheless the association of waist circumference with severity of GERD has not been studied. The primary aim of this study is to compare BMI with waist circumference for their independent association with severity of GERD. The secondary aim is to evaluate independent risk factors of severity of GERD.
