Both dyspeptic and gastro-oesophageal reflux-like symptoms are frequent in the general population, but their degree of overlap is unknown. In severe functional dyspepsia (FD), symptoms are organized in factors associated with pathophysiological mechanisms. The aims of this study were: (i) to assess the prevalence of dyspeptic symptoms with and without overlapping reflux symptoms in the general population and their impact on daily life and on healthcare utilization; and (ii) to compare symptom groupings in the general population to FD patients. A total of 2025 subjects, representative of the Belgian general population, were used in this study. The subjects were submitted to a questionnaire with validated questions on their dyspeptic and reflux symptoms and with evaluators of impact on daily life and use of healthcare resources. Significant dyspeptic symptoms were found in 417 (20.6%). Overlapping reflux symptoms were present in 141 (33.8%). In this group, symptoms were more frequent and more severe. Dyspeptic symptoms induced weight loss (12.7%) and absenteeism (12.4%), affected daily life (61.2%) and generated use of healthcare resources, such as medical consultations (61.4%) and medication (70.9%). Factor analysis revealed a three-component structure with factor 1 including fullness, bloating and early satiety, factor 2 including nausea and vomiting and factor 3 including discomfort, pain, belching and reflux. If forced in a four-factor model, the analysis separates belching as independent factor. Dyspeptic symptoms are frequent in the general population, with overlapping reflux symptoms and increased symptom burden in about a third. [less ▲]

BACKGROUND AND STUDY AIMS: Gastroesophageal reflux disease (GERD) is a common chronic disease that is primarily diagnosed based on symptom severity and frequency. This study gathered epidemiological data in a population of GERD patients and evaluated the added-value of the GERD Impact Scale (GIS), a novel, validated patient questionnaire, as a tool for initial and long-term patient management. PATIENTS AND METHODS: This observational study recruited patients (296 study centers) with symptomatic GERD and a history of erosive, or reflux, esophagitis. Symptoms were assessed by GIS and physician-subject interview and recorded at baseline (visit 1), at 4-6 weeks (visit 2) and 8-14 weeks (visit 3); also recorded at each visit was the physician's assessment of GERD severity and treatment changes. Analyses were performed on an intent-to-treat basis. RESULTS: Subjects (n = 1919; mean age, 55 years) were 54% female. Lifestyle characteristics included stress (approximately 70% of subjects), mean daily consumption of five cups of caffeine-containing beverages (approximately 70%), alcohol consumption of approximately nine units per week (approximately 50%) and smoking/ex-smoker (41%). Proton pump inhibitors were prescribed in 99% of cases: mainly esomeprazole (82%), with a median dose of 40 mg. Prescribed therapy was changed (mainly dosage levels) between visits in approximately 60% of subjects. The severity of GERD symptoms and GIS scores decreased substantially throughout the study. Mean GIS scores correlated positively with increasing GERD severity and clinical judgment at all visits. Physicians reported that the GIS helped them define the appropriate treatment for the patient and to evaluate the patient's response to treatment in 81% of cases. CONCLUSIONS: This study demonstrates the added-value and usefulness of the patient self-assessment GIS as a management tool for GERD. [less ▲]

Frequency of atypical symptoms in patients suffering from gastro-oesophageal reflux disease (GORD) is not well known, and the optimal management of such symptoms has not been well established. Our aims were to set up an observatory of these atypical symptoms of GORD in Belgium and to study the efficacy of one month treatment with esomeprazole 40 mg. Patients and methods : Gastroenterologists; participating in this observational survey were asked to register every new outpatient with symptoms of GORD during a period of 20 consecutive working days. All patients who reported predominant presence of atypical manifestations of GORD were documented and characterized more in detail. In patients with dominant chest pain or ENT symptoms, a treatment with esomeprazole 40 mg daily during 4 weeks was proposed. Results : 90 gastroenterologists included 2864 patients consulting for symptoms suggestive of GORD, including 776 (27.1%) with dominant atypical symptoms. Endoscopy (performed in 2800 patients) showed significantly less oesophagitis in atypical than in typical GORD patients (68% vs. 81.1%; P < 0.0001). Management of atypical GORD patients appeared to be very heterogeneous. Overall 516/776 patients were included in the open phase of treatment with esomeprazole 40 mg, but data for analysis are only available in 228 patients. After one month, symptoms had disappeared in 57.1% and significantly improved in 26.6%. Conclusion : Atypical GORD represents a large number of consultations in gastroenterology in Belgium. It is associated with less endoscopic lesions than typical GORD. Its management is heterogeneous reflecting the lack of guidelines on this topic. Response rate after esomeprazole 40 mg for one month in this open uncontrolled trial was high. This result warrants confirmation in a placebo-controlled trial. [less ▲]
