Cost-of-disease analysis in patients with gastro-oesophageal reflux disease and Barrett's mucosa.
BACKGROUND: Gastro-oesophageal reflux disease (GERD) is a common and frequently chronic condition that causes considerable costs. AIM: To estimate the economic burden caused by patients with erosive and non-erosive reflux disease, and Barrett's oesophagus. METHODS: The Progression of Gastro-oesophageal Reflux Disease study includes a total of 6,215 patients. At baseline, patients were categorized as non-erosive reflux disease, erosive reflux disease, or Barrett's oesophagus according to endoscopic findings alone or as confirmed by histology. Direct and indirect disease-related costs were calculated based on 5,273 patients with complete information in the second year of the study. RESULTS: A total of 73% of the Progression of Gastro-oesophageal Reflux Disease patients had taken GERD medication, 61% had visited a doctor, and 2% had been hospitalized because of GERD during the previous 12 months. Of all employed persons, 6% reported days off work because of GERD. This health resource utilization caused direct costs of 342+/-864 (mean+/-s.d.) and indirect costs of 40+/-473 per patient and year. Total costs for patients with Barrett's oesophagus or erosive reflux disease were higher than those for patients with non-erosive reflux disease. CONCLUSION: Patients with GERD frequently need long-term medication and doctor care. The disorder is associated with a considerable health economic burden to society.

Long-term clinical course of extra-oesophageal manifestations in patients with gastro-oesophageal reflux disease. A prospective follow-up analysis based on the ProGERD study.
BACKGROUND: Gastro-oesophageal reflux disease can be associated with extra-oesophageal reflux disease such as chronic cough or laryngeal symptoms. The aim of this study was to analyse the clinical course of extra-oesophageal reflux disease in a large population with gastro-oesophageal reflux disease and extra-oesophageal reflux disease under routine clinical care. METHODS: ProGERD is a prospective multicentre cohort study of 6215 outpatients with gastro-oesophageal reflux disease. At baseline all patients underwent endoscopies and were interviewed for extra-oesophageal reflux disease. Initial standardised treatment was esomeprazole for up to 8 weeks. After 2 years of follow-up, reflux symptoms and the prevalence of extra-oesophageal reflux disease were assessed. A multivariate analysis was performed with resolved versus persistent symptoms for chronic cough and laryngeal symptoms as dependent predictors. Independent variables were gender, age, body mass index (BMI), alcohol consumption, cigarette smoking, gastro-oesophageal reflux disease classification, history of gastro-oesophageal reflux disease in the family, duration of gastro-oesophageal reflux disease and proton pump inhibitors medication. RESULTS: Four thousand four hundred and four patients (71%) were available for analysis at 2 years, including 570 and 454 patients who had chronic cough and laryngeal disorders at baseline, respectively. In 63% and 74% of the patients, chronic cough and laryngeal disorders had resolved. Patients with persistent respiratory symptoms in year 2 had significantly more reflux symptoms. Further clinically relevant associations were smoking and non-steroidal anti-inflammatory drugs use. According to the multivariate analysis, classification of gastro-oesophageal reflux disease, proton pump inhibitors medication or duration of gastro-oesophageal reflux disease were not associated with the resolution of cough or laryngeal symptoms. CONCLUSION: In most patients with gastro-oesophageal reflux disease and extra-oesophageal reflux disease, respiratory symptoms resolve during long-term routine care. A high reflux symptom load was associated with the persistence of respiratory disorders.

Histological effects of esomeprazole therapy on the squamous epithelium of the distal oesophagus.
BACKGROUND: Proton pump inhibitor therapy has been reported to reduce proliferative changes of the oesophagus significantly in gastro-oesophageal reflux disease (GERD). AIM: To assess the histological effects of esomeprazole treatment on the oesophagus. METHODS: Data were derived from a subgroup of patients participating in the proGERD study, who had either erosive reflux disease (n = 720) or non-erosive reflux disease (n = 35) and who had biopsy data from two sites [(i) 2 cm above the z-line and (ii) at the z-line], obtained at baseline and following treatment with esomeprazole. Proliferative changes of the squamous epithelium were assessed histologically by measuring thickness of the basal cell layer and elongation of the papillae as a percentage of the whole epithelial thickness. RESULTS: In erosive reflux disease patients, the thickness of the basal cell layer and length of the papillae pretreatment were associated with the severity of oesophagitis (P < 0.05), at both biopsy sites. After esomeprazole treatment, baseline thickness and length of papillae were significantly reduced (P < 0.05) at both biopsy sites in non-erosive reflux disease and erosive reflux disease patients (particularly those with Los Angeles grades C and D). CONCLUSION: This demonstrates a strong correlation between severity of GERD and histological parameters. Esomeprazole therapy resulted in clear reversal of proliferative changes observed prior to treatment in the squamous epithelium at both biopsy locations.

Lifestyle factors and symptoms of gastro-oesophageal reflux -- a population-based study.
BACKGROUND: Although the symptoms of gastro-oesophageal reflux disease are common in the general adult population, the aetiology of gastro-oesophageal reflux disease is still largely unknown. Lifestyle factors such as diet, body mass index, and smoking have been frequently suggested as possible risk factors. AIM: In the present study, we investigated the relationship between various lifestyle factors and gastro-oesophageal reflux disease symptoms. METHODS: A total of 7124 subjects were interviewed as part of the German National Health Interview and Examination Survey, a representative sample of the general adult population. We examined a variety of possible risk factors, including age, gender, body mass index, smoking, alcohol consumption, sports and different foods. To investigate the association between lifestyle and symptoms, we used a multiple logistic regression model, including various gastro-oesophageal reflux disease patient characteristics. RESULTS: We found an association among those with reflux symptoms who were overweight and obese (odds ratio: 1.8, 95% confidence interval: 1.5-2.2; odds ratio: 2.6, 95% confidence interval: 2.2-3.2), respectively. Further risk factors included smoking and the frequent consumption of spirits, sweets, or white bread. Physical activity and the consumption of fruits seemed to have some protective effect. CONCLUSIONS: Lifestyle factors -- in particular overweight, obesity and smoking -- were associated with increased reflux symptoms.

[Symptom- versus endoscopy-based diagnosis and treatment of gastroesophageal reflux disease (GERD)].
The current guidelines of the German Society for Digestive Diseases (DGVS) endoscopy recommends for patients representing with reflux symptoms. In daily routine as well as in Guidelines from other countries and international guidelines, however, a symptom-based strategy for the management of patients with reflux disease is favoured. Since either strategies is dependent on specific clinical findings, neither can be recommended. The preference for one or the other strategy depends on the prevalence of so-called alarm symptoms, risk factors for a reflux carcinoma or Barrett's metaplasia, demographic factors, e. g., age and gender, patient's wish and initial response to empirical therapy with proton pump inhibitors (PPI). However, most patients with characteristic reflux symptoms without any alarm symptoms and/or other risk factors can be safely managed with a symptom-based strategy in acute and long-term care.

Esomeprazole 20 mg vs. pantoprazole 20 mg for maintenance therapy of healed erosive oesophagitis: results from the EXPO study.
BACKGROUND: Following initial healing of erosive oesophagitis, most patients require maintenance therapy to prevent relapse. AIM: To compare endoscopic and symptomatic remission rates over 6 months' maintenance therapy with esomeprazole or pantoprazole (both 20 mg once daily) in patients with healed erosive oesophagitis. METHODS: Patients with symptoms of gastro-oesophageal reflux disease and endoscopically confirmed erosive oesophagitis at baseline were randomized to receive esomeprazole 40 mg or pantoprazole 40 mg for up to 8 weeks. Patients with healed erosive oesophagitis and free of moderate/severe heartburn and acid regurgitation at 4 weeks or, if necessary, 8 weeks entered the 6-month maintenance therapy phase of the study. RESULTS: A total of 2766 patients (63% men; mean age 50 years) received esomeprazole 20 mg (n = 1377) or pantoprazole 20 mg (n = 1389) and comprised the intention-to-treat population. Following 6 months of treatment, the proportion of patients in endoscopic and symptomatic remission was significantly greater for those receiving esomeprazole 20 mg (87.0%) than pantoprazole 20 mg (74.9%, log-rank test P < 0.0001). Esomeprazole 20 mg produced a higher proportion of patients free of moderate to severe gastro-oesophageal reflux disease symptoms and fewer discontinuations because of symptoms than pantoprazole 20 mg (92.2% vs. 88.5%, P < 0.001). CONCLUSIONS: Esomeprazole 20 mg is more effective than pantoprazole 20 mg for maintenance therapy following initial healing of erosive oesophagitis and relief of gastro-oesophageal reflux disease symptoms.

Intragastric acidity during treatment with esomeprazole 40 mg twice daily or pantoprazole 40 mg twice daily--a randomized, two-way crossover study.
BACKGROUND: Patients with severe or complicated reflux disease may require higher than standard doses of a proton pump inhibitor for sufficient acid suppression. AIM: To test the hypothesis that esomeprazole 40 mg twice daily is superior to pantoprazole 40 mg twice daily in lowering intragastric acidity. METHODS: In a randomized, single-blinded, two-way crossover study, healthy subjects received esomeprazole 40 mg twice daily or pantoprazole 40 mg twice daily orally for five consecutive days. Continuous ambulatory 24-h intragastric pH was recorded on day 5 of each treatment. RESULTS: Thirty subjects were analysed. Esomeprazole provided significantly higher intragastric pH-values over the 24-h period [median intragastric pH 6.4 for esomeprazole and 5.1 for pantoprazole (P < 0.00005)]. Intragastric pH > 4 was maintained for 21.1 h with esomeprazole and 16.8 h with pantoprazole (P < 0.0001). An intragastric pH > 4 for more than 16 h was achieved in 96.7 and 56.7% of subjects, respectively (P = 0.0002). During night-time the proportion of time with intragastric pH > 4 was 85.4% with esomeprazole and 63.6% with pantoprazole (P = 0.0001). Nocturnal acid break through occurred less frequently on esomeprazole. CONCLUSIONS: Esomeprazole 40 mg twice daily provides better and more consistent intragastric acid control than pantoprazole 40 mg twice daily.

A randomized comparative study of esomeprazole 40 mg versus pantoprazole 40 mg for healing erosive oesophagitis: the EXPO study.
AIM: To assess the efficacy of the 8-week therapy with esomeprazole 40 mg vs. pantoprazole 40 mg for healing erosive oesophagitis (EE) as part of a management study. METHODS: Patients had a history of gastro-oesophageal reflux disease symptoms (> or =6 months) and had suffered heartburn on at least 4 of the 7 days preceding enrollment. Endoscopies were performed to grade EE severity using the Los Angeles (LA) classification system at baseline, 4 and 8 weeks (if unhealed at 4 weeks). Heartburn severity was recorded by patients on diary cards. The primary end point was healing of EE by week 8 of treatment. RESULTS: Of 3170 patients randomized, the intent-to-treat population consisted of 3151 patients (63% male, mean age: 50.6 years, 27% Helicobacter pylori-positive). Esomeprazole 40 mg healed a significantly greater proportion of EE patients than pantoprazole 40 mg at both 4 weeks (life table estimates: esomeprazole 81%, pantoprazole 75%, P < 0.001) and 8 weeks (life table estimates: esomeprazole 96%, pantoprazole 92%, P < 0.001). The median time to reach sustained heartburn resolution was 6 days in patients receiving esomeprazole and 8 days with pantoprazole (P < 0.001). CONCLUSION: Esomeprazole 40 mg is more effective than pantoprazole 40 mg for healing EE and providing resolution of associated heartburn.

Prognostic influence of Barrett's oesophagus and Helicobacter pylori infection on healing of erosive gastro-oesophageal reflux disease (GORD) and symptom resolution in non-erosive GORD: report from the ProGORD study.
BACKGROUND: Adequacy of acid suppression is a critical factor influencing healing in gastro-oesophageal reflux disease (GORD). The European prospective study ProGORD was set up to determine the endoscopic and symptomatic progression of GORD over five years under routine care, after initial acid suppression with esomeprazole. We report on factors influencing endoscopic healing and symptom resolution during the acute treatment phase. METHODS: Patients with symptoms suggestive of GORD underwent endoscopy and biopsies were obtained from the oesophagus for diagnosis of abnormalities, including Barrett's oesophagus (BO). Data from 6215 patients were included in the "intention to treat" analysis, 3245 diagnosed as having erosive reflux disease (ERD) and 2970 non-erosive reflux disease (NERD). ERD patients were treated with esomeprazole 40 mg for 4-8 weeks for endoscopic healing while NERD patients received 20 mg for 2-4 weeks for resolution of heartburn symptoms. RESULTS: Endoscopic healing occurred overall in 87.7% of ERD patients although healing was significantly lower in those with more severe oesophagitis (76.9%) and in those with BO (72.4%), particularly in Helicobacter pylori negative BO patients (70.1%). Age, sex, and body mass index appeared to have no significant impact on healing. Complete heartburn resolution was reported by 70.4% of ERD patients and by 64.8% of NERD patients at the last visit. Only H pylori infection had a significant influence on complete heartburn resolution in the NERD group (68.1% and 63.7% for H pylori positive and H pylori negative, respectively; p = 0.03). CONCLUSION: The presence of Barrett's mucosa, as well as severe mucosal damage, exerts a negative impact on healing. H pylori infection had a positive influence on healing in ERD patients with coexistent BO but no influence on those without BO.

Risk factors of gastroesophageal reflux disease: methodology and first epidemiological results of the ProGERD study.
OBJECTIVE: We describe the design and report the first results of the Progression of Gastroesophageal Reflux Disease (ProGERD) study, to our knowledge the largest prospective study of GERD patients. STUDY DESIGN AND SETTING: Patients were recruited at 1,253 centers in Germany, Austria, and Switzerland. Following an assessment of medical history, all patients were endoscoped and received esomeprazole for 2 to 8 weeks before entering the 5-year observational phase. RESULTS: A total of 6,215 patients (53% male, age 54+/-14) were included. Of these patients, 46% reported at least daily symptoms, 15% were unable to work at least once during the prior year, and 71% had visited a physician due to reflux symptoms. Barrett's esophagus (BE) was found in 11% of our GERD patients. In polychotomous regression analysis, the main factors related to the occurrence of the three GERD subgroups (nonerosive, erosive disease, and BE) were age, gender, duration of GERD, body mass index (BMI), smoking, and previous PPI use. Factors associated with longer disease duration were increasing age, male gender, BMI, increasing symptom severity, presence of erosive GERD or BE, positive family history, and smoking. CONCLUSION: The findings indicate that GERD is a great burden for patients, and has significant socioeconomic implications. The long-term follow-up period with further endoscopic and histologic evaluations, will help further our understanding of the natural course of the disease.

What parameters are relevant for the histological diagnosis of gastroesophageal reflux disease without Barrett's mucosa?
BACKGROUND/AIMS: There are still ongoing controversies as to which histological parameters allow the diagnosis of gastroesophageal reflux disease (GERD). The aim of the present analysis was to relate histological changes of the esophageal squamous epithelium to different severities of GERD. METHODS: Data were obtained from patients participating in the ProGERD study, who had either erosive reflux disease (ERD, n = 3,245) or non-erosive reflux disease (NERD, n = 2,970). 1,475 patients fulfilled our requirement of having complete biopsy data from two sites (2 cm above the z-line and at the z-line). Changes in the squamous epithelium were assessed by measuring the thickness of the basal cell layer and elongation of the papillae as a percentage of the whole epithelial thickness and counting interepithelial inflammatory cells. RESULTS: The most useful parameters for histological assessment of GERD (given as means, 2 cm above the z-line and at the z-line, respectively) were elongation of the papillae: NERD 40.7 and 48.9%; ERD 46.1 and 54.9% and basal cell hyperplasia: NERD 12.7 and 17.9%; ERD 15.7 and 23.0%. The occurrence of intraepithelial lymphocytic infiltrates, however, is dependent on the severity of GERD, and they are more common than neutrophilic and eosinophilic granulocytes. CONCLUSION: This study shows that both NERD and ERD can be diagnosed histologically if biopsies are obtained from the distal esophagus or from the z-line. Intraepithelial inflammatory cells are rare and show a high specificity, but very low sensitivity.

Quality of life in relation to symptoms in patients with gastro-oesophageal reflux disease-- an analysis based on the ProGERD initiative.
AIMS: To determine the impact of gastro-oesophageal reflux disease (GERD) on the quality of life, to assess changes in the quality of life during treatment with esomeprazole and to define factors that can predict these changes. METHODS: Patients with GERD (n=6215) were included in a prospective cohort study (ProGERD). All patients underwent endoscopy and received esomeprazole. At baseline and after 2 weeks of treatment, symptoms and quality of life were assessed. Factors that influenced changes in the quality of life were determined by multiple regression analyses. RESULTS: At baseline, the quality of life in GERD patients was lower than that in the general population, and was similar to that in patients after acute coronary events. No differences in symptoms or quality of life were observed between the subgroups of patients with non-erosive GERD, erosive GERD and Barrett's oesophagus. After treatment with esomeprazole, the symptoms and quality of life were improved in all subscales within 2 weeks (P<0.001). The mean score of the disease-specific quality of life instrument (Quality of Life in Reflux and Dyspepsia Patients) increased from 4.6 to 6.2 points, representing a highly relevant clinical improvement. The generic quality of life (SF-36) reached levels similar to those in the general population, but, again, no difference was found between the three different subgroups of GERD patients. The main factors associated with an improvement in the quality of life after treatment were symptom relief, severe erosive reflux disease, absence of extra-oesophageal disorders, avoidance of non-steroidal anti-inflammatory drug intake and positive Helicobacter pylori status. CONCLUSIONS: GERD causes a significant impairment in the quality of life that can be attenuated or normalized within a time period as short as 2 weeks by treatment with esomeprazole. These findings were similar across the whole GERD patient spectrum.

Prevalence of extra-oesophageal manifestations in gastro-oesophageal reflux disease: an analysis based on the ProGERD Study.
BACKGROUND AND AIMS: Gastro-oesophageal reflux disease (GERD) can be associated with a variety of extra-oesophageal disorders (EED) such as chronic cough, asthma, laryngeal disorder or chest pain. The aim of the study was to estimate and compare the prevalence of EED in a population with symptomatic GERD presenting as either erosive reflux disease (ERD) or non-erosive reflux disease (NERD). METHODS: Baseline data were collected from a prospective, multicentre, open cohort study (ProGERD) in which patients will be followed for 5 years after initial treatment with esomeprazole. Within the framework of this trial, all patients underwent gastroscopy and filled out a questionnaire designed to assess EED. The influence of potential prognostic factors on the prevalence of EED was analysed by multivariate (stepwise logistic regression) analysis. RESULTS: 6215 patients (3303 male, 2912 female; mean age 54 years) presenting with heartburn were included. EED was detected in 32.8% of all patients. The proportion was significantly higher (P = 0.0002) in ERD patients (34.9%) than in NERD patients (30.5%). As judged from the multivariate analysis, female gender, age, oesophagitis of LA grade C/D, duration of GERD disease greater than 1 years and smoking were significantly associated with EED. ERD patients with oesophagitis of LA grade A or B did not have a significantly higher risk of EED than patients with NERD. CONCLUSIONS: Patients with GERD have a high probability of experiencing EED, which may be associated with a number of prognostic factors such as duration and severity of GERD. Extra-oesophageal disorders are slightly, but statistically, more prevalent in ERD than in NERD patients.
