Active clinical trials for "Gastroesophageal Reflux"

Non-cardiac chest pain accounts for 2-5% of all emergency presentations. In the United States, it has been estimated approximately that US$8 billion was spent annually for the initial care of patients suspected to have an acute coronary syndrome, but who were subsequently found not to have coronary artery disease (1). The most common cause of non-cardiac chest pain is gastro-oesophageal reflux disease (2). Two randomized, double-blind, placebo-controlled trials on the use of omeprazole versus placebo for the treatment of NCCP have been published in the western population and reported an efficacy of 62% to 80% (3,4). High-dose omeprazole was used in the previous trials (3,4). Recently, it has been shown that rabeprazole, which is a newly developed benzimidazole proton pump inhibitor, is a more potent and rapid inhibitor of H+,K+-ATPase and acid secretion than omeprazole, lansoprazole and pantoprazole (5,6). Whether the above findings applied to Chinese population is unknown. Thus we would like to propose a randomized double-blind placebo-controlled trial to study the effects of high-dose proton pump inhibitor for the treatment of non-cardiac chest pain in Chinese population. The aim of this study is to evaluate the efficacy of high-dose proton pump inhibitor for the treatment of gastro-oesophageal reflux related non-cardiac chest pain.

The purpose of this study is to determine if esomeprazole 40 mg. once daily improves not only nighttime symptoms but also significantly reduces conscious awakenings associated with gastroesophageal reflux and consequently improves sleep quality.

To determine if administration of Rozerem in comparison to a placebo reduces or eliminates gastroesophageal reflux disease(GERD) symptoms in individuals with both GERD and chronic insomnia.

Urinary tract infection (UTI) is a common problem in childhood associated with vesico-renal reflux (VRR) in 25-40% of children. A persistent VRR and repeated pyelonephritis may predispose to renal scarring and chronic renal failure with an end-stage renal failure in up to 3% of children.Defining a standard behaviour facing VRR in children is not easy because of the lack of reliable evidence. Numbers of studies compare prospectively or retrospectively, medical, endoscopical and surgical treatment.Surgical techniques are effective but invasive and not free of complication. Medical treatment is submissive to a good observance. The introduction of endoscopic techniques permits to prevent UTI and new renal failure by VRR elimination. Since the beginning of the endoscopic treatment, several bulking agents have been proposed. The ideal agent should be easy to inject, stable in time and should be safe. Of course it should be at least as efficient as actual bulking agent. The use of Teflon was the first wave of success of endoscopic treatment. But sudden passion of Teflon has been darkened by the notion of migration. Since, others substances have been proposed, autologous or exogenous, resorbable or not. But none was ideal and no solutions were found facing problem of biocompatibility or long-term stability.Using adipose tissue as a bulking agent is ancient in plastic surgery and indications had known a leap forward in the last century with Coleman who introduced a new technique called "lipostructure". This technique has known a growing interest in the restoration of all volume defects in plastic surgery because of the stability of the graft. We propose to apply this technique to VRR management in children in order to combine innocuousness and efficiency.

Asthma and gastroesophageal reflux disease (GERD) are common disorders, which although are not usually lethal, both have high morbidity, and high healthcare costs. Recent studies have demonstrated that asthma and GERD often co-exists, and that this co-existence is more frequent than just chance. Therefore, studies that characterize associations between these conditions, and, help in the development of interventions will positively impact the outcomes of these patients, which are critically needed. Subjects that participate in this study are required to be between the ages of 4-11 years old. This protocol proposes to enroll 100 children with asthma, on inhaled steroids who have poor asthma control, defined on the basis of frequent symptoms, excessive beta-agonists use, or frequent asthma episodes. The purpose of this research study is to: Determine, whether children with symptomatic, poorly controlled, asthma assigned to treatment with a PPI( Proton Pump Inhibitor), have fewer asthma exacerbations than similar participants assigned to placebo for a similar duration of time Determine whether children treated with Lansoprazole ( i.e., proton pump inhibitor): have a longer time to first exacerbation, have improved lung function, improved asthma symptom scores, improved quality of life, decreased rescue inhaler use, or other asthma medications, reduced emergency room/urgent care/ physician office visits that are asthma related. Determine whether a subgroup of symptomatic asthmatics, who show a greater benefit from PPI's, can be identified.

OBJECTIVES: I. Determine the safety and efficacy of chondrocyte alginate gel suspension in pediatric patients with vesicoureteral reflux. II. Determine the long term efficacy of this treatment regimen in this patient population. III. Evaluate the short and long term avoidance of surgery or antibiotic therapy after this treatment regimen in this patient population. IV. Estimate the risk:benefit ratio of this treatment regimen in these patients.

Anti-reflux mucosectomy (ARMS) may be a new therapy for refractory gastroesophageal reflux disease (RGERD). The aim of the present study is to explore the safety and efficacy of ARMS.

Nonerosive Reflux Disease (NERD) is a common refractory gastrointestinal disease. Proton Pump Inhibitors (PPIs), the preferred drug, have poor response, single target and poor acid inhibition effect in some patients in clinical application. Long-term use of PPI can lead to many side effects, even dependency. The main Traditional Chinese Medicine (TCM)syndrome types of NERD are liver-stomach depression-heat syndrome, spleen deficiency damp-heat syndrome and cold-heat complicated syndrome. TCM syndrome differentiation treatment has the advantages of overall regulation and individualized treatment. The purpose of this study is to evaluate the safety and efficacy advantages of syndrome differentiation series prescription combined with PPIs descending ladder withdrawal in the treatment of patients who use PPIs for a long time that can not stop, and to solve the problems of multiple side effects and dependency caused by long-term use of PPIs.

The aim of this study is to investigate the effect of ligamentum teres cardiopexy on incidence of de Novo GERD.

The purpose of this study is to investigate whether dexlansoprazole can be as effective as double dose PPI to achieve SSR in high BMI cases with reflux esophagitis in Los Angeles grades A & B.
