Active clinical trials for "Gastroesophageal Reflux"

To evaluate the efficacy of 4-week lansoprazole (Takepron) therapy for subjective symptomatic improvement in gastroesophageal reflux disease patients with dyspepsia symptoms

To investigate the efficacy and safety of PARIET twice daily (b.i.d.) in patients with Proton Pump Inhibitor-resistant reflux esophagitis

After laparoscopic total fundoplication (LTF) 12-15% of patients have persistent reflux symptoms and 20-25% develop gas-related symptoms. Reflux symptoms, gas bloating and inability to belch occurring after surgery have been associated with mixed (acid and weakly acid) (MR) or weakly acidic reflux (WAR). To date, few studies have evaluated functional outcome after LTF in patients with MR or WAR, with the majority reporting only short-term results. It has been shown that delayed gastric emptying (DGE) might also be an important factor for abdominal distension and adverse outcome after LTF.9,10 However, the correlation between poor long-term outcome after LTF and DGE is controversial. In addition, the effect of DGE in patients with MR or WAR is poorly investigated.

Multicenter, comparative single-dose pharmacokinetic (PK) study

Even the patients complain GERD symptoms such as heartburn and acid regurgitation the final diagnosis could be reflux esophagitis (RE), non-erosive reflux disease (NERD) and even functional heartburn (FH). In addition, the GERD symptoms are consisted of esophageal symptoms and extraesophageal symptoms. Thus it is necessary to use effective tool for the measurement of GERD symptoms and response of proton pump inhibitor in short time. Several questionnaires have been made for the assessment of GERD symptoms in recent years However, their screening tools do not include the impact of symptoms on everyday life and take a long time to complete the questionnaires. The GERD impact scale (GIS) questionnaire has been developed to compensate for this. It is a simple, one-page, questionnaire to communicate to the doctor the frequency of reflux symptoms and their effect on quality of life, recognizing that it might also prompt clinicians to make appropriate treatment for patients' symptoms. However, there was no report regarding comparison of the characteristics and response to PPI in RE, NERD and FH groups using GIS questionnaire so far.

DESCRIPTION: Minimal data exists on the prevalence of gastroesophageal reflux disease in minority populations. Specific objectives of this K24 research project are to: (1) Provide an estimate of the prevalence of gastroesophageal reflux disease in an urban, African American population; (2) Determine whether specific risk factors including diet, tobacco use, physical activity, and psychosocial stress are important in the targeted population. We will also measure height, weight, and waist/hip circumference to determine the impact of central obesity on reflux. PUBLIC HEALTH RELEVANCE: This research will help doctors to understand the frequency and risks for esophageal reflux disease (heartburn) in African Americans.

The purpose of this research study is to better understand whether information obtained from a pH probe can help physicians predict whether a patient will respond to the medication that is prescribed for laryngopharyngeal reflux (LPR). The current treatment given to individuals who are diagnosed with LPR is a course of proton pump inhibitor (PPI) medication. Subjects who agree to participate in this study will have a small flexible tube (about the width of a piece of cooked spaghetti) placed in their throat. This tube measures the pH in the throat over a period of 24 hours and helps physicians study the relationship between pH level, LPR symptoms, and the effectiveness of PPI therapy. This study may help physicians find out if certain symptoms or characteristics can help them predict if the PPI medication will be effective for each patient. After probe removal, subjects will receive compensation. They will return to the clinic at their regularly scheduled follow-up visit with the physician, 8 to 12 weeks after starting the PPI medication. At that time, subjects can choose to participate in an optional probe placement.

Gastro-esophageal reflux (GER) is a common condition among preterm infants, due to several physiological promoting factors. To limit the potentially harmful widespread of pharmacological treatment, a step-wise approach, which firstly applies conservative strategies, is currently considered the best choice to manage GER in the preterm population. Among the most common conservative strategies, postural measures seem to represent an effective measure to reduce GER features in symptomatic preterm babies, whereas feed thickening is almost ineffective. Non-nutritive sucking (NNS) is a care strategy largely applied in the Neonatal Intensive Care Unit (NICU) settings. The act of swallowing is both reported to trigger the onset of transient lower esophageal sphincter relaxations (TLESRs), thereby eliciting to GER episodes, and to promote the esophageal clearance of refluxate. Hence, a possible effect of NNS on GER features might be hypothesized. This observational, prospective and explorative study primarily aims to explore the effect of NNS, applied by means of a pacifier, on acid and non-acid GER features, evaluated in symptomatic preterm infants (gestational age ≤32 weeks) undergoing a diagnostic combined pH and multiple intraluminal impedance (pH-MII). The secondary aim of this study is to evaluate, in the subgroup of patients with recurrent GER-related apneas, the effect of NNS on cardiorespiratory events, defined as bradycardias and total, central, obstructive, mixed apneas and detected by a simultaneous polysomnographic monitoring.

The purpose of the prospective study is to collect information surrounding lung transplant in order to develop a randomized study to determine if prevention of gastroesophageal reflux disease (GERD) related aspiration (stomach acid coming up from the stomach into the esophagus) by surgical fundoplication improves lung rejection. Lung transplantation has evolved into an effective treatment for patients with end-stage lung disease; however, a significant limitation to long-term survival is patients develop a condition of scarring known as chronic lung rejection, which can cause lung function to deteriorate, thereby reducing a patient's chances for survival. Preliminary research has shown a correlation between the presence of gastroesophageal reflux disease (GERD) and impaired early lung rejection as assessed by a breathing test, FEV1 (the amount of forced expired air volume in 1 second). The Investigator is interested in learning more about this condition and the potential for aspiration (inhaling fluid) injury. The primary goal of this preliminary study will be to identify aspiration markers that are correlated with adverse clinical outcomes (increased early rejection, decreased FEV1) that may be used as inclusion criteria for the future randomized trial. The purpose of the retrospective study is to collect information surrounding lung transplant in order to develop a randomized study to determine if prevention of gastroesophageal reflux disease (GERD) related aspiration (stomach acid coming up from the stomach into the esophagus) by surgical fundoplication improves lung rejection. The goal of this retrospective data collection is to review the following: subject outcome event rates for subjects with and without gastroesophageal reflux disease (GERD) for survival, Bronchiolitis Obliterans Syndrome (BOS), acute rejection and Forced Expiratory Volume in the first second (FEV-1), the estimated treatment effect of fundoplication on the above event rates, a threshold effect for Bronchiolitis Obliterans Syndrome (BOS) and/or death are more likely to occur at higher or more proximal acid or non-acid contact times. This data will be collected in order to better design and coordinate a multicenter prospective study.

The purpose of this study is to confirm the safety profile / factors which impact safety and efficacy of Nexium capsules in daily clinical usage for the patients who have been prescribed Nexium for "gastric ulcer", "duodenal ulcer", "anastomotic ulcer", "reflux oesophagitis", "non-erosive reflux disease", or "Zollinger-Ellison syndrome"
