Filter by: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 compares 4 weeks of treatment with Esomeprazole 20 mg once daily to Placebo in the treatment of Upper Abdominal Pain in patients with Symptomatic Gastroesophageal Reflux Disease (sGERD)
The purpose of this study is to examine the effects of Nexium at a dose of 20mg administered orally compared to intravenously on the maximum acid output in subjects with symptoms of Gastroesophageal reflux disease (GERD).
The purpose of this study is to examine the effects of Nexium at a dose of 40mg administered orally compared to intravenously on the maximum acid output in subjects with symptoms of Gastroesophageal reflux disease (GERD).
Although the symptomatic and epithelial (histologic and endoscopic) response to antireflux therapy are well known and extensively studied, little is known of the genetic events occurring in response to proton pump inhibitor therapy. Preliminary data from our laboratory has shown, for example, that COX-2 expression is not only elevated in patients with gastroesophageal reflux disease but also can be correlated with pathologic esophageal acid exposure on 24 hour pH monitoring. Similar studies have suggested that antireflux surgery may normalize COX-2 gene expression. In contrast studies following ablation of dysplastic Barrett's epithelium have shown persistence of genetic changes associated with altered cellular function, despite the return of the histologic appearance to normal. Several key mediators of inflammation, metaplasia (Barrett's) and neoplasia have now been well characterized and shown to be important factors in the pathogenesis of esophageal injury. It is likely that successful antireflux therapy returns altered expression of these mediators toward normal although this hypothesis remains largely unexplored. The aim of this study is to investigate gene expression of key mediators of the spectrum of esophageal mucosal injury and the response to antireflux therapy. Hypothesis: Antireflux therapy (proton pump inhibitor and surgical fundoplication) normalizes the expression of genes known to be involved in the pathogenesis of inflammation (esophagitis), metaplasia (Barrett esophagus) and neoplasia (adenocarcinoma).
Patients with gastroesophageal reflux disease (heart-burn, acid regurgitation)may benefit from an educational program explaining the medical aspects of the disease, self-management strategies and how to deal with health services. We hypothesized that patients having participated in an educational program would experience an improved quality of life when compared to patients who did not take part (controls).
The purpose of this observational study is to examine RSI (Reflux Symptom Index) and RFS (Reflux Finding Score) by treatment period before and after rabeprazole treatment in LaryngoPharyngeal Reflux Disease(LPRD) patients.
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.
This study will follow ,morbidly obese subjects as they undertake weight loss before and after laparoscopic gastric banding, examining markers of glucose and lipid metabolism, adipokines and measures of body fat.
