Abstract Background:, Overweight and obesity are believed to be risk factors for gastroesophageal reflux disease (GERD). The aim of the present study was to analyze the impact of body mass index (BMI) on the severity and frequency of reflux symptoms and esophagitis in a large cohort of reflux patients. Methods:, As part of the Progression of Gastroesophageal Reflux Disease (ProGERD) study, 6215 patients with clinically assessed GERD were included in the present investigation (53% male, 52 ± 14 years; 47% female, 56 ± 14 years). Heartburn and regurgitation symptoms were assessed using the validated Reflux Disease Questionnaire. Endoscopies were performed and patients were subsequently classified as having non-erosive or erosive disease. To examine the association between BMI, GERD symptoms, and esophagitis, odds ratios (OR) and 95% confidence intervals (95%CI) were calculated using logistic regression models. Results:, In patients with GERD, higher BMI was associated with more frequent and more severe heartburn and regurgitation, as well as with esophagitis. The effects were more pronounced for regurgitation than for heartburn. The strongest association was between obesity and severity of regurgitation symptoms (women: OR 2.11, 95%CI 1.60,2.77; men: OR 2.15, 95%CI 1.59,2.90). Obese women, but not men, had an increased risk of severe esophagitis compared to women with normal weight (OR 2.51, 95%CI 1.53,4.12). Conclusions:, In patients with GERD, higher BMI was associated with more severe and more frequent reflux symptoms and esophagitis. [source]

Summary Background, Currently there is no consensus on the optimal method to measure the severity of dyspepsia symptoms in clinical trials. Aim, To validate the 7-point Global Overall Symptom scale. Methods, The Global Overall Symptom scale uses a 7-point Likert scale ranging from 1 = no problem to 7 = a very severe problem. Validation was performed in two randomized-controlled trials (n = 1121 and 512). Construct validity: Global Overall Symptom was compared with the Quality of Life in Reflux And Dyspepsia, Gastrointestinal Symptom Rating Scale, Reflux Disease Questionnaire and 10 specific symptoms using Spearman correlation coefficients. Test,retest reliability: The Intraclass Correlation Coefficient was calculated for patients with stable dyspepsia defined by no change in Overall Treatment Effect score over two visits. Responsiveness: effect size and standardized response mean were also calculated. Results, Construct validity: Change in Global Overall Symptom score correlated significantly with Quality of Life for Reflux And Dyspepsia, Gastrointestinal Symptom Rating Scale, Reflux Disease Questionnaire and specific symptoms (all P < 0.0002). Reliability: The Intraclass Correlation Coefficient was 0.62 (n = 205) and 0.42 (n = 270). Responsiveness: There was a positive correlation between change in Global Overall Symptom and change in symptom severity. The effect size and standardized response mean were 1.1 and 2.1, respectively. Conclusion, The Global Overall Symptom scale is a simple, valid outcome measure for dyspepsia treatment trials.

Symptom overlap in patients with upper gastrointestinal complaints in the Canadian confirmatory acid suppression test (CAST) study: further psychometric validation of the reflux disease questionnaire

Summary Background The reflux disease questionnaire (RDQ) is a short, patient-completed instrument. Aims To investigate the psychometric characteristics of the RDQ in patients with heartburn-predominant (HB) and non-heartburn predominant (NHB) dyspepsia. Methods HB (n = 388) and NHB (n = 733) patients were randomized to esomeprazole 40 mg daily or twice daily for 1 week, followed by 3 weeks of esomeprazole 40 mg daily. Results High factor loadings (0.78,0.86) supported the ,regurgitation' dimension of the RDQ. Overlapping factor loadings in the ,heartburn' and ,dyspepsia' dimensions suggested symptom overlap. All dimensions demonstrated high internal consistency (Cronbach's alpha: 0.79,0.90). Intra-class correlation coefficients over 4 weeks were good (0.66,0.85). The RDQ showed good responsiveness over 4 weeks of treatment, with high effect sizes (,0.80). Moderate or large symptom improvements were reported by 90% and 77% of HB and NHB patients, respectively, following treatment. Patients who responded to acid suppression also experienced symptom benefits in all RDQ dimensions. Conclusions The RDQ is reliable, valid and responsive to change in HB and NHB patients. The symptom overlap is important but need not play a major role in determining treatment strategy as both patient groups benefited from proton pump inhibitor treatment. [source]


Do we need a new gastro-oesophageal reflux disease questionnaire?

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 5 2004
V. Stanghellini
Summary Background :,Gastro-oesophageal reflux disease (GERD) is highly prevalent in Western countries. Because the majority of patients do not present with endoscopic abnormalities, the assessment of the symptom severity and quality of life, and their response to treatment, has become increasingly important. Self-assessed symptom questionnaires are now key instruments in clinicaltrials. Aim :,To evaluate the validity of available GERD measurement tools. Methods :,An ideal GERD symptom assessment instrument, suitable as a primary end-point for clinical trials, should possess the following characteristics: (i) be sensitive in patients with GERD; (ii) cover the frequency and intensity of typical and atypical GERD symptoms; (iii) be multidimensional (cover all symptom dimensions); (iv) have proven psychometric properties (validity, reliability and responsiveness); (v) be practical and economical; (vi) be self-assessed; (vii) use ,word pictures' which are easy to understand for patients; (viii) respond rapidly to changes (responsiveness over short time intervals); (ix) be used daily to assess changes during and after therapy; and (x) be valid in different languages for international use. Results :,A literature review revealed five scales that met some of the above characteristics, but did not fulfil all criteria. Conclusion :,There is a need for a new evaluative tool for the assessment of GERD symptoms and their response to therapy. [source]
