Filter by:The purpose of this survey is to evaluate the safety and effectiveness of vonoprazan tablets in patients with gastric ulcer, duodenal ulcer, and reflux esophagitis in the routine clinical setting.
The study will take place at Rambam medical center, department of Otolaryngology Head and Neck Surgery, for two years. Patients suspected of LPR or laryngeal l tumor and are candidate for laryngeal or hypopharyngeal biopsies will be recruited.
The purpose of this survey is to evaluate the safety and effectiveness of long-term administration of vonoprazan tablets when used as maintenance therapy for reflux esophagitis in routine clinical settings.
The prevalence of GERD is estimated to be as high as 20% in the US, and up to 50% remain symptomatic on proton pump inhibitor (PPI) therapy. The clinical approach to understand the mechanism of nonresponse is not standardized, and patients will often undergo various tests: 1) pH-impedance, 2) wireless pH monitoring over 96 hours, 3) high-resolution impedance manometry (HRIM), and 4) mucosal impedance (MI). Controversy exists regarding the best technique, optimal study protocol and treatment approach for the PPI non-responder (PPINR) group, resulting in inappropriate resource utilization and a failure to provide effective personalized care. The first aim is to identify the relevant physiologic parameters of diagnostic tools in their ability to predict PPI requirement. In Aim Two, these results will be applied to guide the formal development of a clinical algorithm for the management of PPINRs with personalized clinical pathways based on mechanism of treatment failure. We will first perform a prospective comparison trial of 240 PPINR subjects at 2 sites over 4 years. Subjects will complete symptom questionnaires and undergo diagnostic testing (pH-impedance on PPI therapy, HRIM, 96-hr wireless pH monitoring off PPI therapy and MI). Those who have a positive pH study and/or resume PPI therapy will receive escalation of therapy with dexlansoprazole. We will compare the ability of 96-hr wireless pH monitoring vs pH impedance to predict PPI requirement and response to dexlansoprazole, respectively. We will explore whether MI is equivalent to 96-hr wireless pH monitoring in predicting PPI requirement. Lastly, we will determine whether HRIM metrics can be utilized to determine reflux burden, mechanism and response to treatment. Next, the investigators will develop quality measures for reflux testing in order to develop a simplified management strategy for the PPINR group. The RAND/UCLA Appropriateness Methodology will be utilized with an expert working group to develop formal validated quality measures for reflux testing.
The purpose of this study is to determine the efficacy and safety of DWP14012 compared to esomeprazole in the treatment of erosive gastroesophageal reflux disease classified as Los Angeles(LA) classification grades A to D.
The effect of chlorpromazine (Largactil) on esophageal sensitivity will be investigated in this study. Overnight fasted subjects will be asked to fill out 2 questionnaires to assess the emotional status before their onset of the stimulation tests. The multimodal stimulation probe will be positioned through the mouth in the distal esophagus. After the ingestion of the stimulation probe, 10mg of chlorpromazine or placebo (saline) will be slowly administered via intravenous injection. Hereafter the multimodal stimulation tests will be initiated. Esophageal sensitivity will be assessed by performing thermal, mechanical, electrical and chemical stimulation of the esophagus. The chlorpromazine condition will be compared with a placebo condition, this will be organised on 2 separate study visits in a randomised order.
The investigators prospectively studied ninety nine GERD patients following laparoscopic hiatal surgery combined with transoral incisionless fundoplication at two community hospitals. General surgeons and gastroenterologists participated in the study. GERD questions were recorded before and at six and twelve months.
Infants often present to the hospital with episodes of coughing, choking, gagging, change in muscle tone, and/or change in skin color, known as brief resolved unexplained event. Many studies have tried to address why infants have these symptoms and if there is a way to prevent them from happening again. Currently, there is no clear agreement on the most common cause of these symptoms or how to prevent them. Some studies have suggested that gastroesophageal reflux can cause these symptoms. The investigators are conducting a study of infants who are admitted to Boston Children's Hospital with episodes of coughing, choking, gagging, change in muscle tone, and/or change in skin color, symptoms that could be reflux. The investigators want to determine if these symptoms can be prevented by changing the way infants are fed, either by giving them a formula to treat reflux or by thickening their feeds to treat reflux. The goal of the study is to determine if different types of feeding interventions prevent infants from coming back to the hospital.
Rapid onset of proton-pump inhibitors to achieve a fast symptom is an unmet need in treating gastroesophageal reflux disease (GERD) but there was no report on the short-term clinical effects and timing to symptom relief comparing dexlansoprazole 60 mg to esomeprazole 40 mg. This pilot study aims to compare the one-week clinical effects of single doses of the two drugs in treating GERD patients.
The purpose of this study is to exploratorily evaluate the effect of vonoprazan 20 mg on sleep disturbance of patients with reflux esophagitis, who have heartburn and/or regurgitation and ≥ 6.0 in the Pittsburgh Sleep Quality Index (PSQI) global score despite the maintenance treatment with PPI other than vonoprazan.
