NCT ID: NCT01806220 Completed - Clinical trials for Gastroesophageal Reflux Disease

Laryngeal and Esophageal EGF-r Expression in Patients With Reflux Laryngitis

EGFR
Start date: January 2004
Phase: N/A
Study type: Interventional

- Saliva plays an important role in the homeostasis of the digestive tract mucosa. - Salivary organic components, such as the Epidermal Growth Factor(EGF) have been found in defficient concentrations in patients with gastroesophageal reflux disease (GERD) and reflux related laryngitis (LPR). - The epidermal growth factor receptor (EGFR) signaling pathway is one of the most important pathways that regulate growth, survival, proliferation, and differentiation in mammalian cells - Eperdermal growth factor receptor (EGFR) overexpression has been linked to hyperproliferative diseases. - It is unknown if the inflammatory process in GERD is realated to difficiencies in EGFR expression. - The objective of the current study was to try to establish a correlation between the expression of EGFR in the laryngeal and esophageal mucosa and the severity of laryngitis in adults with GERD and LPR

NCT ID: NCT01755221 Completed - Clinical trials for Extraesophageal Reflux

Positive Predictive Value of the Dx-pH Probe for Predicting PPI Response in LPR

Start date: August 2012
Phase:
Study type: Observational

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.

NCT ID: NCT01389401 Completed - Clinical trials for Gastroesophageal Reflux Disease (GERD)

Salivary Epidermal Growth Factor (EGF) Concentration Before and After Treatment of Reflux Laryngitis

Start date: January 2009
Phase: N/A
Study type: Observational

- Saliva plays a key role in the homeostasis of the digestive tract - The reflux of gastroesophageal contents may cause damage to the esophageal, laryngeal and pharyngeal mucosas - There seems to be no correlation between the severity of reflux episodes and the intensity of inflammatory changes, suggesting individual protective mechanisms to refluxate exposure - Inorganic and Organic Salivary changes have been associated to Gastroesophageal Reflux Disease (GERD) and its supraesophageal manifestations, especially reflux laryngitis (Laryngopharyngeal Reflux- LPR) - Decreased salivary Epidermal Growth factor (EGF) concentrations have been found in patients with GERD and LPR, but it is unclear if these are primary or secondary to the disease. - Hypothesis: The decreased salivary EGF concentrations in patients with reflux laryngitis is primary and therefore would not change after treatment and control of the disease

NCT ID: NCT00628667 Completed - Clinical trials for Chronic Posterior Laryngitis (CPL)

Chronic Posterior Laryngitis With Suspected Laryngopharyngeal Reflux

Start date: February 2002
Phase: Phase 4
Study type: Interventional

This study looks at how effective acid suppression therapy is on symptoms associated with chronic posterior laryngitis (CPL) in patients with documented pharyngeal acid reflux.

NCT ID: NCT00611390 Completed - Viral Tracheitis Clinical Trials

Treatment of Acute Tracheitis and Laryngitis With Essential Oils of Aromatic Plants

Start date: January 2008
Phase: Phase 1/Phase 2
Study type: Interventional

This randomized, double blind, parallel group study, compared the efficacy of spray containing aromatic essential oils of some herbal plants, against placebo in the treatment of patients with acute viral Laryngitis or Tracheitis. Study objectives: Primary to demonstrate a hoarseness or cough relief within 20 minutes after first administration of treatment with the spray. Secondary to demonstrate a reduction of a defined symptoms sum score based on symptoms and signs comparing baseline therapy from the beginning to the end of 3 days treatment

NCT ID: NCT00517114 Completed - Clinical trials for Gastroesophageal Reflux

Prospective Double-blinded Randomized Controlled Trial of 12-weeks High Dose Rabeprazole (Pariet) in the Treatment of Reflux Laryngitis in Chinese Patients

Start date: January 2005
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the efficacy of rabeprazole (pariet) versus placebo in treating reflux laryngitis in Chinese patients. Patients who attend the voice clinic of Department of ENT, Queen Mary hospital with suspected reflux laryngitis will be recruited. A questionnaire will be administered by the research assistant of the Department of Medicine and ENT, Queen Mary hospital. A 12-week course of PPI versus placebo trial will be commenced and patients' symptoms and signs will be documented at 6-week and 12-week time. The study will finish after a 12-week course of rabeprazole.

NCT ID: NCT00369265 Terminated - Clinical trials for Laryngopharyngeal Reflux

Safety and Efficacy of Lansoprazole 30mg Twice Daily in Treatment of Laryngitis Associated With Gastroesophageal Reflux

Start date: August 2006
Phase: Phase 4
Study type: Interventional

The purpose of this study is to determine whether Lansoprazole 30mg taken twice daily is effective in the treatment of laryngitis due to gastroesophageal reflux.
