Abstract
Background The association between Helicobacter pylori and reflux esophagitis (RE) remains controversial. This study aimed to prospectively evaluate the effect of H. pylori eradication on RE and gastroesophageal reflux (GERD) symptoms in H. pylori-positive patients who underwent endoscopic resection of gastric neoplasm. Methods Of the 244 patients enrolled in this study, 173 H. pylori-positive patients underwent follow-up at least once. We evaluated the prevalence of RE and GERD symptoms in these patients following H. pylori eradication. Results There were 75.7% (131/173), 78.6% (125/159), and 78.9% (105/133) subjects who were successfully eradicated after 6, 12, and 18–24 months, respectively. During the 2-year follow-up period, the eradication of H. pylori did not increase the incidence of RE (OR 0.93; 95% CI, 0.49–1.77, p = 0.828). H. pylori status was also not associated with the development of GERD symptoms (OR 1.12; 95% CI, 0.47–2.95, p = 0.721). In the univariate analysis for RE, present smoking history (OR 4.79; 95% CI 1.98–11.60, p = 0.001), present alcohol consumption history (OR 2.18; 95% CI 1.03–4.63, p = 0.041), and diabetes mellitus (OR 2.44; 95% CI 1.02–5.86, p = 0.045) were found to be associated with RE. Multivariate analysis showed that present smoking history (OR 4.54; 95% CI 1.84–11.02, p = 0.001) was a significant risk factor for RE. Conclusions H. pylori eradication did not increase the incidence of RE or GERD symptoms in patients who underwent endoscopic resection of gastric neoplasm.

Abstract
Background: Helicobacter pylori (H. pylori) frequently colonizes the stomach. Gastroesophageal reflux disease (GERD) is a common and costly disease. But the relationship of H. pylori and GERD is still unclear. This study aimed to explore the effect of H. pylori and its eradication on reflux esophagitis therapy. Methods: Patients diagnosed with reflux esophagitis by endoscopy were enrolled; based on rapid urease test and Warth–Starry stain, they were divided into H. pylori positive and negative groups. H. pylori positive patients were randomly given H. pylori eradication treatment for 10 days, then esomeprazole 20 mg bid for 46 days. The other patients received esomeprazole 20 mg bid therapy for 8 weeks. After treatment, three patient groups were obtained: H. pylori positive eradicated, H. pylori positive uneradicated, and H. pylori negative. Before and after therapy, reflux symptoms were scored and compared. Healing rates were compared among groups. The χ2 test and t-test were used, respectively, for enumeration and measurement data. Results: There were 176 H. pylori positive (with 92 eradication cases) and 180 negative cases. Healing rates in the H. pylori positive eradicated and H. pylori positive uneradicated groups reached 80.4% and 79.8% (P = 0.911), with reflux symptom scores of 0.22 and 0.14 (P = 0.588). Healing rates of esophagitis in the H. pylori positive uneradicated and H. pylori negative groups were, respectively, 79.8% and 82.2% (P = 0.848); reflux symptom scores were 0.14 and 0.21 (P = 0.546). Conclusions: Based on esomeprazole therapy, H. pylori infection and eradication have no significant effect on reflux esophagitis therapy.

Abstract
PURPOSE OF REVIEW The purpose of the review is to discuss key studies conducted on the intriguing relationship between Helicobacter pylori and gastroesophageal reflux disease. RECENT FINDINGS Epidemiological studies have repeatedly described a negative association between H. pylori infection and erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma, but not between H. pylori and gastroesophageal reflux disease symptoms. Especially, infection with CagA-positive strains appears to protect the distal esophagus by causing fundic gland atrophy and impaired gastric acid secretion. Although earlier reports suggested the development of erosive esophagitis after H. pylori eradication, more recent studies discuss that H. pylori eradication usually does not have an important clinical impact on gastroesophageal reflux disease. SUMMARY Gastric atrophy is the most widely accepted mechanism by which the distal esophagus is protected from abnormal acid exposure in patients with H. pylori infection. The clinical impact of H. pylori infection on the prevalence of erosive esophagitis and Barrett's esophagus remains a matter of debate. In areas with a high prevalence of H. pylori-induced atrophic gastritis, the protection that this infection may afford against gastroesophageal reflux disease is not comparable to the risk that H. pylori poses for the development of gastric cancer.

Abstract
A possible association between gastroesophageal reflux disease (GERD) and Helicobacter pylori (H. pylori) infection has been the subject of study and debate in recent years. This review discusses the pathophysiological and immunological mechanisms implicated in this relationship. Although gastric secretion in the majority of H. pylori-infected individuals is unaltered, this review considers how the bacteria may interfere with gastric acid production and what role it may play in GERD. We also identify the epidemiological evidence that confirms that GERD develops after the infection has been eradicated. Lastly, we clarify how the host's immune response and bacterial virulence factors interfere with this relationship, explaining the highly conflicting results in the literature.

Abstract
Helicobacter pylori (H. pylori) remains a prevalent, worldwide, chronic infection. Though the prevalence of this infection appears to be decreasing in many parts of the world, H. pylori remains an important factor linked to the development of peptic ulcer disease, gastric malignanc and dyspeptic symptoms. Whether to test for H. pylori in patients with functional dyspepsia, gastroesophageal reflux disease (GERD), patients taking nonsteroidal antiinflammatory drugs, with iron deficiency anemia, or who are at greater risk of developing gastric cancer remains controversial. H. pylori can be diagnosed by endoscopic or nonendoscopic methods. A variety of factors including the need for endoscopy, pretest probability of infection, local availability, and an understanding of the performance characteristics and cost of the individual tests influences choice of evaluation in a given patient. Testing to prove eradication should be performed in patients who receive treatment of H. pylori for peptic ulcer disease, individuals with persistent dyspeptic symptoms despite the test-and-treat strategy, those with H. pylori-associated MALT lymphoma, and individuals who have undergone resection of early gastric cancer. Recent studies suggest that eradication rates achieved by first-line treatment with a proton pump inhibitor (PPI), clarithromycin, and amoxicillin have decreased to 70-85%, in part due to increasing clarithromycin resistance. Eradication rates may also be lower with 7 versus 14-day regimens. Bismuth-containing quadruple regimens for 7-14 days are another first-line treatment option. Sequential therapy for 10 days has shown promise in Europe but requires validation in North America. The most commonly used salvage regimen in patients with persistent H. pylori is bismuth quadruple therapy. Recent data suggest that a PPI, levofloxacin, and amoxicillin for 10 days is more effective and better tolerated than bismuth quadruple therapy for persistent H. pylori infection, though this needs to be validated in the United States.

Abstract
OBJECTIVES To compare the efficacy and tolerability of pantoprazole 20 mg once daily with that of esomeprazole 20 mg once daily for 6 months as maintenance therapy in patients with previously healed gastroesophageal reflux disease. METHODS In an initial open-label acute phase, outpatients with endoscopically confirmed gastroesophageal reflux disease (Los Angeles grades A-D) received pantoprazole 40 mg once daily for 4 or 8 weeks. Those healed (defined as the absence of esophagitis, and 'no' or 'mild' heartburn and acid regurgitation) were randomized in the double-blind manner for maintenance therapy with pantoprazole 20 mg once daily or esomeprazole 20 mg once daily for 6 months. RESULTS In the acute healing phase, 1452 patients were recruited to receive pantoprazole 40 mg once daily. Healing success was 91% (intent-to-treat analysis). A total of 1303 patients entered the maintenance phase of the study. Pantoprazole 20 mg once daily and esomeprazole 20 mg once daily were equally effective at maintaining patients in remission; 84 and 85% of pantoprazole and esomeprazole recipients remained in combined endoscopic and symptomatic remission at 6 months (intent-to-treat analysis). The confidence interval of the difference was (-5.7; +infinity), showing that pantoprazole is as effective as esomeprazole with a noninferiority margin of 5.8%. Combined endoscopic and symptomatic remission was independent of Helicobacter pylori status. Both treatments were well tolerated and safe. CONCLUSION Treatment with pantoprazole 20 mg once daily or esomeprazole 20 mg once daily provides similarly effective and well-tolerated maintenance of previously healed gastroesophageal reflux disease irrespective of baseline H. pylori status.

Abstract
This paper reviews new literature data from March 2004 to April 2005 about the association between Helicobacter pylori and non-malignant disease of the upper gastrointestinal tract. Eradication of H. pylori is indicated for all patients with non-malignant diseases associated with this pathogen. However, its effect is variable, ranging from the highest benefit in the cure of peptic ulcer disease to a small benefit in patients with non-ulcer dyspepsia. Test and treat strategy is still cost-effective for management of patients with uninvestigated dyspepsia. The only limitations of the strategy are the patient's age and the cost benefit ratio in case of low prevalence of the infection. H. pylori eradication is of value in chronic NSAID users, but is insufficient to prevent NSAID-related ulcer disease. In developed countries H. pylori eradication does not cause gastro-esophageal reflux disease (GORD), however, a negative association between H. pylori and GORD does exist, especially in Asia, but the nature of this relationship should be further clarified.

Abstract
PURPOSE OF REVIEW Gastroesophageal reflux disease is a very common disorder. Proton pump inhibitors are the highly successful mainstay of medical gastroesophageal reflux disease treatment. However, some limitations of proton pump inhibitor therapy continue to drive studies that aim at better understanding and managing manifestations of gastroesophageal reflux disease. This review summarizes recent progress in our understanding of the pathophysiology and treatment of gastroesophageal reflux disease. RECENT FINDINGS Recent studies have demonstrated a potential role of increased gastric acid secretion in gastroesophageal reflux disease, a factor largely neglected during the last decade. Failure to respond adequately to proton pump inhibitor therapy has been attributed to diagnostic inaccuracy, to nocturnal acid breakthrough, to ongoing non-acid reflux and to esophageal hypersensitivity. The relevance of nocturnal acid breakthrough has been recently challenged. Transient lower esophageal sphincter relaxations are a major mechanism of gastroesophageal reflux disease; inhibition of transient lower esophageal sphincter relaxations is a potentially important therapeutic target. Recent studies have focused on GABA receptor stimulation using baclofen or sodium valproate. The role of esophageal body peristalsis in the clearance of reflux events has been questioned. Endoscopic antireflux therapies aim at perendoscopic reinforcement of the antireflux barrier as a novel therapeutic approach to gastroesophageal reflux disease. At present, long-term and controlled data are scarce. Recent observations have challenged the long-term efficacy of surgical antireflux therapy. SUMMARY Increased understanding of the pathophysiology of gastroesophageal reflux disease may lead to new or improved treatments. Major advances have been made in the role of gastric acid secretion, the control of transient lower esophageal sphincter relaxations and mechanisms underlying esophageal hypersensitivity. Recent studies have highlighted some shortcomings of proton pump inhibitor therapy and of antireflux surgery. Novel approaches are treatments aimed at decreasing transient lower esophageal sphincter relaxations and endoscopic antireflux procedures. Large-scale controlled studies are lacking for both treatments.

Abstract
BACKGROUND The majority of gastro-oesophageal reflux disease (GERD) seems to be non-erosive reflux disease. Nonerosive reflux disease includes minimal change oesophagitis (whitish or reddish, oedematous change and erosion that is not regarded as mucosal break) and no endoscopic abnormalities. AIM To investigate the accurate proportion of those with minimal change oesophagitis and to clarify its characteristics. In addition, we evaluated the effect of famotidine (40 mg/day) in those with minimal change. METHODS Prospective endoscopic assessment was performed for consecutive 606 out-patients. Of the 582 patients suitable for analysis, 347 were non-treated. The latter were divided into those with erosive GERD or minimal change, and their endoscopic findings and characteristics were compared. RESULTS Among 347 non-treated patients, 88 (25%) had erosive GERD and 249 (72%) had minimal change. Compared with patients who have erosive GERD and those with minimal change, the latter were less likely to have hiatal hernia or bile reflux, but more likely to have gastric atrophy. Symptomatic patients (n = 55) with minimal change oesophagitis were more likely to have hiatal hernia than those who were asymptomatic (n= 194). Most patients preferred taking famotidine on-demand, during a 4-week follow-up period. CONCLUSIONS Most non-erosive reflux disease can be classified as minimal change oesophagitis, and that have different characteristics from erosive GERD. On-demand famotidine may be a suitable alternative treatment for patients with minimal change disease.
