Although nasal polyposis has been recognized as an inflammatory process for many years, the true etiology of nasal polyposis mainly unknown. Despite surgical removal, the recurrence rate after surgery has been reported as high as 87% within the first year after surgery. Anecdotally the Principal Investigator found an incidence of pH probe-proven laryngopharyngeal reflux approaching 80% in his patients with nasal polyposis. Although his number of cases was small, the incidence of recurrence of polyps in these patients was 17%. The PI believes that such an association is too great to be explained by chance alone, and deserves further study. He anticipates two contributions to the literature from this study, the first documenting the incidence of extraesophageal (laryngopharyngeal) reflux in patients with polyposis, and the second showing the impact of reflux treatment on the recurrence rate of the polyps, initially after one year of therapy.
The hypothesis for this study is that potent anti-secretory therapy with high dose PPI improves asthma control regardless of either asthma severity or the presence of GERD symptoms.
Obstructive Sleep Apnea (OSA) is common in modern society, affecting up to 5% of working middle-aged adults in the United States. Obesity is the number one risk factor for the development of OSA. Consequences of untreated OSA are varied and significant and included numerous neuropsychiatric parameters such as mood alterations, depression, anxiety, diminished social interactions, and decreased quality of life. Mounting evidence suggests that treatment of OSA can improve many of these outcomes. The primary treatment modality for this condition is continuous positive airway pressure (CPAP). This device delivers positive pressure to the upper airway in order to prevent its collapse during sleep. Unfortunately, many patients do not choose to use CPAP or have difficulty with these devices. This results in many individuals with OSA either going without therapy or unable to reap the full benefits of treatment. Gastroesophageal reflux (GERD) is also common in the United States and may, in some instances, be directly related to weight gain. Survey studies have suggested that symptomatic GERD is more common in patients with OSA. Whether there exists a cause and effect relationship between these two conditions is not known at present. It has been suggested that GERD may contribute to OSA by narrowing the upper airway. This study will examine the effect of treatment of GERD on mild to moderate OSA. Fifty individuals identified as having mild to moderate OSA (diagnosed by overnight sleep study or PSG) and GERD (confirmed by an esophageal probe) will be enrolled. Both men and women will be included in this study and no "special populations" will be utilized. Subjects will fill out questionnaires to subjectively measure sleepiness, OSA-related symptoms, GERD-related symptoms, and sleep apnea-related quality of life. They will then be randomized to receive either 12 weeks of the proton pump inhibitor lansoprazole (Prevacid) or placebo (twenty five subjects per group). Upon completion of the 12 week trial, subjects will return and the following data will be collected; repeat all of the baseline questionnaires, repeat PSG and repeat pH probe. Results from this study will help to establish the relative effectiveness of a novel form of therapy for a common yet difficult to manage medical condition. . The risks to subjects enrolled in the study are minimal and therefore the benefit to risk ratio is heavily in favor of performing the study.
The purpose of this study is to decide if controlling stomach acid is related to healing of erosive esophagitis after treatment with esomeprazole magnesium (NEXIUM®) 10 mg and 40 mg once daily.
The purpose of the study is to follow the medical course of children with moderate to severe asthma and see how this relates to whether they have acid of non-acid gastroesophageal reflux
Gastroesophageal reflux disease is a frequent disease and which heavily affects the patients' quality of life. To alleviate symptoms and ease the healing of lesion, patients very often need to continuously take anti-secretory drugs (Proton pump inhibitors or PPIs), which, despite their efficiency, do not cure the disease. For these PPI dependent patients, an anti-reflux surgery (fundoplication often made by coelioscopy) is a possible alternative but it has a significant morbidity rate and even an estimated post-operative mortality of 0.8% outside of expertise centres. Therefore, new therapeutic endoscopic approaches, supposed to be less invasive and less expensive than surgery have been developed during the last three years. Among them, radiofrequency (Stretta® procedure) consists in administering a high frequency current in the cardia area, in order to induce thanks to a thermal effect a sub-mucous remodelling and a modification of the compliance of the cardia regionThe aim of this project carried out in 8 French centres and 2 European centers is to assess through a randomised trial, the efficiency of radiofrequency on PPI dependent patients. The study will be carried out in 2 phases with patients who have been fully informed of the project statement, and particularly of the potential risks of the radiofrequency technique and have given their written acceptation to participate to the study.The first phase, which will last 6 to 11 weeks, will aim at making sure that patients are PPI dependent and define their needs. After this initial phase, patients will be randomised between those who will carry on with the PPI treatment or the radiofrequency treatment. The follow up after this randomisation will last one year. The first assessment of the therapeutic efficiency will be done at 6th month. The 6 additional follow up months will be required for the assessment of mid-term side effects of the treatment and the rate of symptomatic recurrences.
The purpose of the study is to demonstrate the intended use of the Gatekeeper Reflux Repair System to provide symptomatic relief is subjects with gastroesophageal reflux disease.
The purpose of this study is to demonstrate pharmacodynamic comparability between the pantoprazole spheroid formulation and the marketed tablet formulation.
Patients with a clinically indicated sleep study will be enrolled in this study. They will have a diagnostic and a therapeutic sleep study with continuous positive airway pressure ventilation. For both studies a pH probe will be placed nasal to measure the amount of acidic reflux during each study. Baseline levels of reflux from the diagnostic sleep study will be compared to reflux episodes while on continuous positive airway pressure ventilation.
