Filter by:A double-blind study comparing Esomeprazole Magnesium 40 mg once daily and Lansoprazole 30 mg twice daily to control the symptoms in patients with gastroesophageal reflux disease (GERD) with continued heartburn symptoms with a course of therapy of 30 mg twice daily Lansoprazole.
This study includes patients with sleep disturbances associated with gastroesophageal reflux disease (GERD) and has 3 treatment arms. Patients will receive only one of the following treatment arms: esomeprazole 20 mg once daily, esomeprazole 40 mg once daily, matching placebo once daily. The relief to the sleep disturbances will be assessed.
The purpose of this study is to determine whether Dexlansoprazole once daily (QD) is effective in treating patients with night heartburn.
This study looks at controlling intragastric pH following administration of esomeprazole 40 mg, lansoprazole 30 mg and pantoprazole 40 mg taken orally, once daily in patients taking either non-selective or cyclooxygenase-2 (COX-2) selective nonsteroidal anti-inflammatory drugs (NSAIDs).
Gastroesophageal reflux (GER) is frequent in children with asthma, can induce bronchspasm, and increase airway reactivity. Children with asthma are often treated for GER with drugs to supress gastric acid production. However, this treatment is expensive, and with unproven benefit. The primary objective of this study is to conduct a multi-site, randomized, clinical trial to test the hypothesis that treatment of GER with lansoprazole, an approved proton pump inhibitor, will decrease the frequency of exacerbations in children with poorly controlled asthma. The study will include 300 asthmatic children treated with inhaled corticosteroids, 6-16 years of age, with poor control defined by frequent symptoms, excessive beta agonist use, or frequent exacerbations. Participants will be randomly assigned to treatment with either lansoprazole or placebo for 6 months. The presence, severity, and relationship of GER to asthma symptoms will be determined with 24 hour esophageal pH monitoring, but randomization to treatment will not be influenced by the presence or severity of GER. The primary outcome measure is the proportion of participants who have exacerbations of asthma defined by diaries and interviews. Secondary outcome measures include asthma symptom and control scores, GER symptoms, lung function, and unscheduled health care contacts. Pre-defined subgroup analyses will examine the relationship between specific clinical features and the response to lansoprazole. Treatment response will also be evaluated with 3-hour post-dose plasma lansoprazole concentrations, and related to polymorphisms in the gene CYP2C19, the cytochrome P450 pathway, and interleukin-1 (IL-1) beta, a pro-inflammatory cytokine. Tertiary studies will determine how the magnitude of GER impacts airways inflammation, as measured by the concentrations of hydrogen ions (pH) and nitric oxide in expired breath. The results of this trial sould have a major impact on the understanding and treatment of GER in children with asthma.
Heartburn or reflux disease affects about 20% of Americans. 50 - 70% of people who have endoscopy for reflux disease have a normal appearing esophagus. Confocal Laser Microscopy allows us to see changes in the cells not visable during routine endoscopy. Whe goal of this study is to identify the use of this new technique in diagnosing reflux in patients who have normal appearing esophagus.
The purpose of this research is to study the level of acid exposure above the gastroesophageal junction and the distal esophagus in patients with reflux symptoms using a capsule type acid measurement system. Patients with reflux symptoms are likely to have more acid reflux just above the junction of the stomach and the esophagus that may help to improve the diagnosis of gastroesophageal reflux disease (GERD). This may help better treat the reflux symptoms.
The purpose of this study is to evaluate the effect of each of the rabeprazole treatment regimens on nocturnal heartburn symptoms.
Gastric distress is a common phenomenon in our society. Heartburn and regurgitation occur daily in about 7% of the adult population,weekly 14-20% pf the adults and monthly in 34-44% of adults. The yearly prevalence of recurrent stomach complaints are frequent reason for consulting a primary care physician and are an important reason for using OTC medication. A good diagnosis is important as functional GERD with possible complications such as strictures and Barrett's esophagus or ulcer disease with life threatening complications such as bleeding & perforations. The clinical diagnosis of reflux disease is mainly based on symptom evaluation. This, however, is hindered by the variety of complaints with different etiology. Treatment with a proton pump inhibitor can be used to confirm the diagnosis reflux disease. A major part of the patients with acid related stomach complaints indeed will experience symptom relief after starting PPI therapy. In this view, it is important to identify these patients who will react on treatment with PPI in quick, accurate, non-invasive and cheap manner. The Reflux Impact Scale (RIS) is validated, short, self explanatory questionnaire which asks for the presence & impact of reflux symptoms. The RIS is developed for PCP to aid in the evaluation & selection of these patient who will profit from treatment with PPI. The aim of this present study is to determine which questions of the RIS can be predictive for reaching treatment success with PPI. Treatment success is determined by asking for patients' satisfaction & completion of the McMaster Overall Treatment Evaluation Heartburn questionnaire.
The purpose of this study is to compare the treatment effect in patients with upper gastro-intestinal complaints with an elevated risk for NSAID-associated GI-damage to those without an elevated risk for NSAID-associated damage (as determined by the treating physician).
