BACKGROUND The presence of Lewy bodies and Lewy neurites (LN) has been demonstrated in the enteric nervous system (ENS) of Parkinson's disease (PD) patients. The aims of the present research were to use routine colonoscopy biopsies (1) to analyze, in depth, enteric pathology throughout the colonic submucosal plexus (SMP), and (2) to correlate the(More)
We have shown that routine biopsies of the ascending colon obtained at colonoscopy allow the detection of Lewy neurites (LN) in the enteric nervous system (ENS) of Parkinson's disease (PD) patients. Although colonoscopy is a relatively safe procedure, it requires colon preparation and anesthesia. The present study was therefore undertaken to evaluate(More)
Parkinson's disease is the second most common neurodegenerative disease after Alzheimer's disease. It has been classically considered that the pathological hallmarks of Parkinson's disease, namely Lewy bodies and Lewy neurites, affect primarily the substantia nigra. Nevertheless, it has become increasingly evident in recent years that Parkinson's disease is(More)
Lewy pathology affects the gastrointestinal tract in Parkinson's disease (PD) and data from recent genetic studies suggest a link between PD and gut inflammation. We therefore undertook the present survey to investigate whether gastrointestinal inflammation occurs in PD patients. Nineteen PD patients and 14 age-matched healthy controls were included. For(More)
BACKGROUND Gastrointestinal reflux disease (GERD) is a common disorder that negatively impacts health-related quality of life (HRQL) and work productivity. Many patients have only a partial response to proton pump inhibitor (PPI) therapy and continue to experience GERD symptoms despite optimized treatment. This observational study aimed to provide(More)
Background/Aims There is a need for a simple and practical tool adapted for the diagnosis of chronic constipation (CC) in the Asian population. This study compared the Asian Neurogastroenterology and Motility Association (ANMA) CC tool and Rome III criteria for the diagnosis of CC in Asian subjects. Methods This multicenter, cross-sectional study included(More)
BACKGROUND AND STUDY AIMS Adequate bowel preparation is key for the optimal quality of colonoscopy. The sodium phosphate laxatives used for preparation may induce gastric injuries. However, in vivo studies monitoring the effects of sodium phosphate on the gastric mucosa are currently lacking. We aimed to characterize the effects of sodium phosphate tablets(More)
BACKGROUND Obesity is associated with a risk of gastroesophageal reflux disease. The pharmacodynamic efficacy of proton pump inhibitors has not been specifically evaluated in obese subjects. The aim of this study was to compare the antisecretory response to a single oral dose of 20 mg rabeprazole, 20 mg omeprazole and placebo in obese subjects. METHODS(More)
BACKGROUND As illustrated by the Montreal classification, gastroesophageal reflux disease (GERD) is much more than heartburn and patients constitute a heterogeneous group. Understanding if links exist between patients' characteristics and GERD symptoms, and classify subjects based on symptom-profile could help to better understand, diagnose, and treat GERD.(More)
CONTEXT Gastro-oesophageal reflux disease (GORD) is a common chronic disorder that has severe impact on quality of life and often requires continuous acid-suppression therapy. Proton-pump inhibitors (PPIs) are extremely effective but expensive, and do not restore the normal antireflux barrier at the gastro-oesophageal junction. Antireflux surgery, even with(More)
