Prevalence of severe esophagitis in Spain. Results of the PRESS study (Prevalence and Risk factors for Esophagitis in Spain: A cross-sectional study).

BACKGROUND: *N.P. and M.P. contributed equally to this study.The current prevalence of esophagitis in southern Europe is unknown. In addition, the risk factors for reflux esophagitis are not fully understood. OBJECTIVE: The objective of this article is to assess the prevalence and risk factors for esophagitis in Spain. METHODS: A prospective, observational, cross-sectional, multicenter study (PRESS study) was conducted among 31 gastrointestinal endoscopy units throughout Spain. A total of 1361 patients undergoing upper gastrointestinal endoscopy were enrolled. Sociodemographic, clinical and treatment data were recorded. RESULTS: A total of 95% of patients were Caucasian and 52% were male (mean age: 53 ± 17 years). The most frequent symptoms prompting endoscopy were heartburn (40%), regurgitation (26%) and dysphagia (15%). Fifty-four percent of patients undergoing endoscopy were receiving proton pump inhibitor (PPI) treatment. Esophagitis (mainly mild-moderate) was present in 154 (12.4%) patients. The severe form was recorded in only 11 (0.8%) patients. Multivariate analysis results indicated that the likelihood of esophagitis was higher in men (OR = 1.91, 95% CI = 1.31-2.78), in patients with high GERD-Q scores (OR = 1.256, 95% CI = 1.176-1.343), weight increase (OR = 1.014, 95% CI = 1.003-1.025) and high alcohol consumption (OR = 2.49, 95% CI = 1.16-5.36). CONCLUSION: Severe esophagitis is a rare finding in the Spanish population. Male gender, high GERD-Q score, weight increase and high alcohol consumption are main risk factors for its appearance.

Usefulness of penicillamine-stimulated urinary copper excretion in the diagnosis of adult Wilson's disease.

OBJECTIVE: Diagnosis of Wilson's disease (WD) is reliant on liver biopsy (LB) and measurement of hepatic copper. The aim of this study was to determine the usefulness of penicillamine-stimulated urinary copper excretion (PS-UCE), a non-invasive diagnostic test, for the diagnosis of WD in adults. MATERIAL AND METHODS: In this prospective study of patients with suspected WD, total serum copper, ceruloplasmin, basal 24-h UCE and PS-UCE levels were measured. LB with copper determination was performed in those patients with persistent hypertransaminasemia and low ceruloplasmin or basal UCE > 40 microg/24 h. Diagnosis was established if the ceruloplasmin level was found to be < 20 mg/dl and hepatic copper > 250 microg/g. Results. A total of 115 patients were studied; LB was performed in 43, and WD was diagnosed in 6 (13.9%). Significant differences between WD and non-WD patients were found for basal UCE (WD: median 134.3 microg/24 h versus non-WD: median 19.0 microg/24 h (p < 0.05)) and PS-UCE (WD: median 1284.0 microg/24 h versus non-WD: median 776.0 microg/24 h; p < 0.01). In the ROC (receiver-operated curve) analysis, PS-UCE was the best discriminant between WD and non-WD (area under the curve (AUC) = 0.911, best cut-off point 1057 microg/24 h, 100% sensitivity, 82.3% specificity). CONCLUSIONS: PS-UCE is probably a useful non-invasive test in the diagnosis of WD, improving the selection of patients for diagnostic liver biopsy. Patients with PS-UCE under 1057 microg/24 h only rarely will suffer from WD and are unlikely to benefit from LB.

Acceptability of lansoprazole orally disintegrating tablets in patients with gastro-oesophageal reflux disease : ACEPTO study.

OBJECTIVE: To assess the acceptability of lansoprazole orally disintegrating tablets (LODT) in patients with gastro-oesophageal reflux disease (GORD). METHODS: A multicentre, observational, cross-sectional study of patients diagnosed with GORD aged > or =18 years under the care of 272 gastroenterologists. Acceptability was determined by global patient assessment whereby the drug's organoleptic characteristics and properties were evaluated by a self-administered 11-item ad hoc questionnaire with a 5-point Likert-type scale. RESULTS: A total of 734 patients (mean age 49.6 years [SD = 15.2]) with GORD who had been prescribed LODT > or =14 days prior to inclusion in the study were evaluable for the main endpoint. Of these, 51.1% were men. Most patients (80.7%) had been treated with doses of LODT 30mg/day for an average of 52.7 days (SD = 59.3). Overall, 93.6% of patients rated LODT treatment as 'very acceptable' or ''acceptable'. The degree of acceptability was associated with the perception that the formulation helps treatment compliance (p < 0.001). The drug's properties were rated as follows: size 'neither large nor small' (70.0%); flavour 'very pleasant' or 'pleasant' (75.2%); intensity of flavour 'neither strong nor mild', 'mild' or 'very mild' (86.1%); no 'sandy sensation' (53.4%); speed of dissolving 'fast' or 'very fast' (80.2%); use of tablets 'very easy' or 'easy' (92.4%) and use of tablets 'very convenient' or 'convenient' (91.0%). Three adverse reactions, none of them serious, were reported in three patients (0.4%). CONCLUSIONS: LODT were well accepted by patients with GORD. Patients reported that this formulation improved compliance with therapy. Tolerability was excellent.

The prevalence of peptic ulcer not related to Helicobacter pylori or non-steroidal anti-inflammatory drug use is negligible in southern Europe.

BACKGROUND AND AIM: Helicobacter pylori is the major cause of peptic ulcer disease, but the proportion of H. pylori-negative peptic ulcers seems to be increasing in developed countries. We investigated the frequency of H. pylori-negative peptic ulcer without intake of nonsteroidal anti-inflammatory drugs (NSAIDs) in a Mediterranean European country. MATERIALS AND METHODS: We prospectively collected consecutive patients with an endoscopically verified active peptic ulcer over 6 months from different areas of Spain. Helicobacter pylori infection was assessed by rapid urease test and histologic examination (corpus and antral biopsies). A (13)C-urea breath test was performed if H. pylori was not detected with the invasive test. Patients were considered H. pylori-negative if all three tests were negative. NSAID use was determined by structured data collection. RESULTS: Of 754 consecutive peptic ulcer patients, 16 (2.1%) were H. pylori-negative and had not used NSAIDs before the diagnosis. Of the 472 patients who had duodenal ulcers, 95.7% (n = 452) were H. pylori-positive and only 1.69% (n = 8) were negative for both H. pylori infection and NSAID use; 193 patients had benign gastric ulcers and 87% (n = 168) of them were infected by H. pylori (p <.001 vs. duodenal ulcers). NSAID intake was more frequent in gastric ulcer patients (52.8%) than in duodenal ulcer patients (25.4%; p <.001). Consequently, the frequency of H. pylori-negative gastric ulcer in patients not using NSAID was 4.1% (n = 8). CONCLUSION: Peptic ulcer disease is still highly associated with H. pylori infection in southern Europe, and only 1.6% of all duodenal ulcers and 4.1% of all gastric ulcers were not associated with either H. pylori infection or NSAID use.
