Active clinical trials for "Gastroesophageal Reflux"

Gastroesophageal reflux disease is increasing worldwide. The causes of reflux symptoms are not found exactly. especially, the postprandial reflux symptoms are more common than the all day reflux symptoms. One of the causes of reflux symptoms is the relaxation of the lower sphincter of the esophagus. But, the sphincter relaxation also occur in normal people. But, there is a difference in postprandial reflux pattens between the patients and the normal people. So, in this study, we want to compare the difference of reflux pattern between the patients who have postprandial reflux symptoms and normal people though the 24hr pH monitoring.

The aims of the study: To evaluate whether the use of a specific TENS technology can improve GERD symptoms and esophageal acid exposure.

Study Hypothesis: This study is designed as an integral part of the development of new or improved features or components of the Bravo® pH Monitoring System and may serve verification and validation purposes The study population will include a group of healthy volunteers (Group A) and a group of symptomatic patients with known or suspected gastroesophageal reflux disease (Group B). Group A: Healthy volunteers will not undergo invasive procedure. These volunteers may be asked to carry the capsule and\or Bravo Recorder. These procedures will serve to evaluate different technical matters such as human interface, ergonomic aspects and communication performances of the system Group B: Symptomatic patients will undergo invasive procedure, including Bravo capsule delivery, positioning and attachment. Confirmation of capsule attachment may be done by endoscopically. These procedures will serve to evaluate overall system performance in actual clinical setup, for instance: Bravo Recorder performance including communication quality, human interface and similar, ergonomics of delivery device, pH Capsule performance, etc. Subjects from both study groups as well as physician may be asked to provide feedback on the procedure and/or document their activities during the procedure.

The purpose of this 9-day study is to determine if: Pantoprazole modifies the steady-state plasma concentrations of orally administered psychotropic medications including valproic acid, lithium, and second-generation antipsychotics (i.e., aripiprazole, asenapine, clozapine, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, ziprasidone) Serum gastrin levels change within a week of starting or stopping pantoprazole

Reflux symptoms index (RSI) were developed to identify a clinical index of suspicion for laryngopharyngeal reflux (LPR) in patients with ear, nose, and throat symptoms. RSI is an efficient diagnostic tool for LPR/ It is easy to use, even for those who know little about LPR. It does not require special equipment or examinations and is inexpensive. Thus, it can be considered highly efficient and cost-effective. The study will focus on translating and testing the RSI into Kazakh language and comparing its results in healthy people and people with laryngopharyngeal reflux.

Healthcare delivery now mandates shorter visits with higher documentation requirements, undermining the patient-provider interaction. Electronic health records (EHRs) have the potential to improve outcomes and quality of care in this pressured environment, and are endorsed by the Patient Protection and Affordable Care Act (ACA) and Health Information Technology for Economic and Clinical Health (HITECH) Act as an important mechanism to support value-based healthcare. However, EHR systems were principally designed to support the transactional needs of administrators and billers, less so to nurture the relationship between patients and their providers. The purpose of this research is to identify ways to use EHRs to support clinical gastroenterologists and their patients while meeting the meaningful use requirements of the HITECH Act. To improve clinic visit efficiency and meet criteria for meaningful use, investigators developed a patient-provider portal (P3) that systematically collects patient symptoms using a computer algorithm called Automated Evaluation of Gastrointestinal Symptoms (AEGIS). AEGIS utilizes computerized adaptive testing (CAT) to guide patients through questions drawn from a library of over 300 symptom attributes measuring the timing, severity, frequency, location, quality, and character of their GI symptoms, along with relevant comorbidities, family history, and alarm features. The system then automatically "translates" the patient report into a full narrative HPI available for use by GI providers in an EHR. In a cross-sectional study in the American Journal of Gastroenterology comparing AEGIS versus physician-documented HPIs, investigators found that blinded physician reviewers perceived that AEGIS HPIs were of higher overall quality, better organized, and more succinct, comprehensible, complete and useful compared to HPIs written by physicians during usual care in academic GI clinics. In the current study, investigators aim to evaluate computer-generated HPIs prospectively on a wider scale in diverse academic and community-based settings. Moreover, investigators aim to test an enhanced AEGIS intervention that ties patient HPIs to an individualized "education prescription" which guides the patient through a library of multi-media educational materials on GI symptoms, conditions, and treatments.

The purpose of this study is to elucidate mechanisms whereby oxidative stress induced by acute reflux esophagitis: 1) activates p38 to regulate proteins that control the G1/S cell cycle checkpoint, and 2) activates HIFs (hypoxia inducible factors) to cause autocrine VEGF (vascular endothelial growth factor) signaling that triggers the EMT (epithelial-mesenchymal-transition) program in Barrett's esophagus.

This proposed trial is designed to answer the following questions: First, is biliary reflux to the distal esophagus present before OLGB and does it increase after the procedure? Second, does performing an OLGB with or without anti-reflux sutures make a difference in (biliary) reflux exposures of the distal esophagus? To answer these questions the investigators plan to perform a randomized, controlled trial involving two groups. Group A will undergo an OLGB without anti-reflux sutures and consists of 50 patients. Group B will receive an OLGB with anti-reflux sutures and also consists of 50 patients. Gastroscopic evaluation for inflammation and reflux will be performed before and one year after the operation utilizing multilevel intraluminal impedance pH-monitoring (MII-pH) and intragastric Bilitec 2000™. Furthermore, the study will be blinded to the patient. Long-term weight loss, the resolution of comorbidities and the incidence of surgical complications will serve as secondary endpoints. Follow-ups will be performed at 3, 6, and 12 months postoperatively to assess all primary and secondary goals.

Proton Pump Inhibitors (PPI) are standard in the therapy of pediatric GERD. In the past it has been hypothesized, that either direct inhibition of bacterial ATPase or elevation of the pH may lead to changes in the intestinal microbiome. Small series published in adults suggest a predominance of streptococci, a possible reason for increased incidences of pneumonia under PPI therapy. Studies in children are yet scarce. This study will include 20 infants. GERD will be verified by 24h-intraluminal impedance monitoring. All patients will have undergone conservative measures prior to initiation of PPI therapy (due to persisting symptoms). Children will receive a commercial PPI for 8 weeks (esomeprazole 1mg/kg/day). Stool samples will be collected before initiation of PPI, under PPI (4 weeks after initiation) and 8 weeks after discontinuing PPI therapy. The intestinal microbiome will be determined by 16S rDNA-based microbial community profiling by high-throughput pyrosequencing. Data will be compared by dependent non parametric test (Wilcoxon). P-values <0.05 will be considered statistically significant.

Sedation is defined as the act of administrating a sedative drug to produce a state of calm or sleep. Sedation is commonly given to a patient in hospital settings to provide a tolerable and pleasant experience by relieving anxiety, pain and discomfort, as well as to expedite the duration of the procedure. Moderate sedation (conscious sedation) is the preferred state of sedation, whereby self-maintenance of ventilation and hemodynamic stability is achieved. The primary objective of this study is to determine if inhalational Sevoflurane is a more superior sedative agent in terms of faster psychomotor recovery and time taken to fulfil discharge criteria when compared with intravenous Midazolam sedation. Secondary objective is to determine if inhalational Sevoflurane sedation has better patient's and endoscopist's satisfaction when compared with intravenous Midazolam sedation.
