Abstract
Proton pump inhibitors (PPIs) are used worldwide to treat of acid-related disorders such as peptic ulcer and gastroesophageal reflux disease and to prevent gastroduodenal injuries due to nonsteroidal anti-inflammatory drugs. PPIs are the most potent inhibitors of gastric acid secretion currently available, and they are one of the most commonly prescribed classes of drugs because of their high efficacy and low toxicity. However, long-term PPI use causes histopathological changes such as parietal cell protrusion into the gland lumen, cystic dilation of gastric fundic glands, and foveolar epithelial hyperplasia. These changes can manifest on endoscopic examination as fundic gland polyps, hyperplastic polyps, multiple white and flat elevated lesions, cobblestone-like mucosa, or black spots. Clinicians must be aware of PPI-induced endoscopic features in patients with chronic long-term PPI use. Conversely, identifying patients with long-term PPI use based on their endoscopic findings is important. Recently, potassium-competitive acid blockers (P-CABs), a new class of acid suppressants that inhibit gastric acid secretion more strongly than PPIs, have recently been introduced clinically. Further long-term prospective studies on these gastric mucosal lesions in patients with either PPI or P-CAB use are required to investigate their association with histopathological changes and to establish the clinical significance of these findings.

Aliment Pharmacol Ther 2015; 42:649-63. [PMID: 26177572 DOI: 10.1111/apt.13324] [Citation(s) in RCA: 159] [Impact Index Per Article: 17.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2015] [Revised: 04/03/2015] [Accepted: 06/28/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUND Proton pump inhibitors (PPIs) have a well-established safety profile. However, concerns have been raised about a potential relationship between PPI-induced hypergastrinaemia and the development of enterochromaffin-like (ECL) cell hyperplasia, neuroendocrine tumours and gastric cancer during long-term therapy. AIM To review the effects of long-term PPI use on serum gastrin levels and gastric histopathology. METHODS A systematic literature search was conducted in PubMed on 21 April 2015 to identify studies reporting the effects of long-term (defined as >3 years) PPI use on gastrin levels and gastric histopathology. RESULTS A total of 16 studies (1920 patients) met the inclusion criteria. During long-term PPI therapy, mean gastrin levels rose to one to three times the upper limit of the normal range (~100 pg/mL), and an increased prevalence of ECL cell hyperplasia was observed (+7.8-52.0%). Helicobacter pylori-positive patients had a significantly increased risk of developing ECL linear/micronodular hyperplasia compared with H. pylori-negative patients [OR: 2.45 (95% CI: 1.47-4.10), P = 0.0006]; however, no evidence of neoplastic changes was found. The risk of corpus atrophy was markedly higher in H. pylori-positive patients than in H. pylori-negative patients [OR: 11.45 (95% CI: 6.25-20.99), P < 0.00001]. Not a single case of gastric adenocarcinoma was found. CONCLUSIONS Long-term PPI therapy induced moderate hypergastrinaemia in most patients and an increased prevalence of ECL cell hyperplasia. H. pylori-positive patients receiving long-term PPI therapy were exposed to a higher risk of corpus atrophy than H. pylori-negative patients. No neuroendocrine tumours or gastric cancers were found.

Abstract
BACKGROUND The evolution of gastro-oesophageal reflux disease (GERD) under current management options remains uncertain. AIM To examine whether, depending on the initial presentation, non-erosive (NERD) and erosive reflux disease (ERD) without Barrett's oesophagus will progress to more severe disease under current routine care following the resolution of the initial condition. METHODS Patients with the primary symptom of heartburn were included at baseline, and stratified into non-erosive (NERD) and erosive reflux disease (ERD), LA grades A-D (Los Angeles classification). After a 2- to 8-week course with esomeprazole therapy to achieve endoscopic healing in ERD and symptom relief in NERD, patients were treated routinely at the discretion of their physician. We report oesophagitis status and the presence of endoscopic and confirmed Barrett's oesophagus after 5 years. RESULTS A total of 6215 patients were enrolled in the study of whom 2721 patients completed the 5-year follow-up. Progression, regression and stability of GERD severity were followed from baseline to 5 years. Only a few patients with NERD and mild/moderate ERD progressed to severe forms of ERD and even Barrett's oesophagus. Most patients remained stable or showed improvement in their oesophagitis; 5.9% of the NERD patients, 12.1% of LA grade A/B patients and 19.7% of LA grade C/D patients in whom no Barrett's oesophagus was recorded at baseline progressed to endoscopic or confirmed Barrett's oesophagus at 5 years. CONCLUSION Most GERD patients remain stable or improve over a 5-year observation period under current routine clinical care.

Abstract
OBJECTIVE To examine the risk of developing strictures in patients with erosive and non-erosive gastroesophageal reflux disease in a community-based setting, since controlled trials indicate that the use of proton pump inhibitors renders the risk of strictures insignificant. MATERIAL AND METHODS A 17-year cohort study of 4706 patients referred to endoscopy due to upper GI symptoms, with a population comparison cohort of 47,060 individuals. All patients were followed and treated according to prevailing guidelines by their usual care provider. Main outcomes were relative risks (RR) and 95% confidence intervals (CI) for incident strictures and dilatations. RESULTS 776 (16.5%) patients were diagnosed with erosive esophagitis, particularly men (61.2%). Over a period of 1-17 years (mean 10.5), 20 patients (2.6%) in the esophagitis group developed a peptic stricture, necessitating one or more dilatations in 16 patients (2.1%). Among the non-esophagitis patients, the incidences for both outcomes were 1.2%. Male gender doubled the risk of developing strictures, and alcohol abuse raised the risk four folds. Erosive patients had a risk of developing strictures eight times (95% CI: 5.0-13.0) higher than controls, whereas non-erosive patients' risk was 4.0 (95% CI: 2.8-5.7). The majority of strictures developed within the first 10 years after a diagnosis of esophagitis. CONCLUSION Patients with esophagitis had eight times higher risk of strictures than population controls and two times higher than dyspeptic patients without esophagitis. This indicates that long-term outcomes in general practice are poorer than in controlled trials, most likely due to a lack of compliance with medication.

Abstract
OBJECTIVES Proton pump inhibitors (PPIs) are frequently prescribed to patients with Barrett's esophagus (BE), but in a subset, they can induce significant hypergastrinemia. Elevated levels of gastrin have been associated with tumorigenic effects in a number of gastrointestinal cancers. We decided to investigate the association between serum gastrin levels and dysplasia in BE. METHODS We performed a cross-sectional study and enrolled patients with BE without dysplasia, low-grade dysplasia (LGD), high-grade dysplasia (HGD), or adenocarcinoma (AC), as well as gastroesophageal reflux disease controls, all chronically taking PPIs. Fasting serum gastrin was measured, and data were collected on patient characteristics, medication use, and the highest degree of BE neoplasia. RESULTS A total of 95 patients were enrolled. The mean age was 64.7 (+/-10.0) years, and 70.5% were male. The median serum gastrin level was 40 pM. There was no significant difference in gastrin levels with increased degrees of BE neoplasia (overall P=0.68). In multivariable analysis, the highest quartile of gastrin was associated with significantly increased odds of advanced neoplasia (HGD or AC) (odds ratio (OR): 5.46, 95% confidence interval (CI): 1.20-24.8). CONCLUSIONS In BE patients taking PPIs, an elevated serum gastrin is associated with a history of HGD or AC. Prospective studies are needed to determine whether patients with nondysplastic BE and elevated serum gastrin are at increased risk for neoplastic progression.

Abstract
OBJECTIVES Gastroesophageal reflux disease (GERD) is a chronic condition that usually requires long-term maintenance therapy with proton-pump inhibitors (PPIs). In clinical practice, patients receive PPIs at the lowest dose to control symptoms. However, it is not known whether this approach adequately controls acidic esophageal reflux. We sought to investigate the efficacy of three different dosages of esomeprazole in patients receiving maintenance therapy for GERD, using the Bravo pH system. METHODS Patients with a previous history of erosive esophagitis A or B (LA classification) that was healed at the time of enrollment or endoscopy-negative reflux disease (ENRD), documented with an abnormal pH study, were randomized to receive maintenance therapy with esomeprazole 40 mg twice daily (group A), once daily (group B), or every other day (group C). Intraesophageal pH was monitored for two consecutive days using the Bravo wireless system, 30 days after randomization. The parameters subjected to analysis were percent of total time pH<4 and the De Meester score. RESULTS The pH results from 73 patients (group A=24, group B=24, group C=25 patients) were subjected to final analysis. On the first day of the study, the mean (+/-s.d.) percent of total time pH <4 and the De Meester score were group A: 0.9(1.2) and 4.1(4.0); group B: 1.5(1.6) and 7.0(6.9); group C: 1.3(1.0) and 6.0(3.3), respectively (P=0.262 and 0.134, respectively). On the second day of the study, the corresponding values were group A: 0.7(1.0) and 3.9(5.9); group B: 1.5(1.8) and 6.4(6.6); group C: 7.0(4.4) and 29.4(19.4), respectively. The difference was statistically significant (P<0.0001 and <0.0001, respectively). Further analysis showed that patients not receiving PPI had a significantly higher mean percent of total time pH<4 and De Meester score as compared with patients on PPI once or twice daily (P<0.001 and <0.001 respectively). CONCLUSIONS The administration of esomeprazole 40 mg every other day does not control acidic esophageal reflux on the day off PPI. Esomeprazole 40 mg once daily effectively controls reflux of acid in patients with history of mild esophagitis or ENRD, whereas doubling the dose does not seem to confer any further advantage.

Abstract
BACKGROUND A higher body mass index (BMI) may lead to a more adverse outcome of reflux esophagitis. The study aimed to determine whether increased BMI after H. pylori eradication in duodenal ulcer patients predisposes to erosive reflux esophagitis. METHODS Four hundred fifty-nine patients with Helicobacter pylori-positive duodenal ulcers but without reflux esophagitis were evaluated. Serial BMIs were collected before therapy and on the 2nd, 6th, and 12th months after H. pylori eradication. New-onset reflux esophagitis was recorded. RESULTS In 350 patients with complete follow-up, mean BMI increased from the second month after H. pylori eradication (P<0.001). H. pylori eradication also led to a net increase of BMI >1.5 kg/m in nearly 20% of patients in the 12-month follow-up, whereas new-onset of reflux esophagitis was noted in 16.3% (57/350). Baseline BMI, prevalence rate of hiatus hernia, and net increase of BMI were higher in patients with new-onset reflux than in those without (P<0.05). Multiple logistic regression confirmed higher baseline BMI, hiatus hernia, and net BMI increase >1.5 kg/m after H. pylori eradication were independently associated with new-onset reflux esophagitis (P<0.05). CONCLUSIONS Eradication of H. pylori may lead to a significant net increase of BMI in patients with duodenal ulcers. Such BMI gain, as well as higher baseline BMI and hiatus hernia, predisposes to new-onset reflux esophagitis after H. pylori eradication.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are the most commonly used pharmacological treatment for gastroesophageal reflux disease (GERD). OBJECTIVE To examine the utilization patterns of PPIs and other GERD-related medications, satisfaction with PPI treatment and presence of GERD symptoms. PATIENTS AND METHODS GERD patients using prescription PPIs were identified from a mixed-model HMO health plan. Utilization patterns of PPIs and other GERD medications, satisfaction with PPI treatment and presence of GERD symptoms were assessed using questionnaires. RESULTS Among the 617 patients who completed the survey, 71.0% used PPIs once a day (QD), 22.2% used twice a day (BID) and 6.8% more than twice a day or on an as-needed basis. Approximately 42.1% of all patients supplemented their prescription PPIs with other GERD medications, including over-the-counter medications and H(2)-receptor antagonists. Over 85% of the patients still experienced GERD symptoms and 82.7% nighttime symptoms. Overall, 72.8% of all patients were satisfied or very satisfied with their PPI treatment. LIMITATIONS The study used self-reported data which may have been subject to recall bias. As the study was conducted in a specific region of the US, the results may have limited generalizability to other US regions or countries. CONCLUSIONS Patients on PPI treatment often experience GERD symptoms and supplement their prescription PPIs with other GERD medications. A substantial proportion of GERD patients receiving PPI treatment are on a BID regimen. Furthermore, more than a quarter of the patients are not completely satisfied with their PPI treatment.

Abstract
BACKGROUND Dexlansoprazole MR employs a dual delayed-release delivery system that extends drug exposure and prolongs pH control compared with lansoprazole. AIM To assess the efficacy and safety of dexlansoprazole MR in healing erosive oesophagitis (EO). METHODS Patients in two identical double-blind, randomized controlled trials (n = 4092) received dexlansoprazole MR 60 or 90 mg or lansoprazole 30 mg once daily. Week 8 healing was assessed using a closed testing procedure--first for non-inferiority, then superiority, vs. lansoprazole. Secondary endpoints included week 4 healing and week 8 healing in patients with moderate-to-severe disease (Los Angeles Classification grades C and D). Life-table and crude rate analyses were performed. Symptoms and tolerability were assessed. RESULTS Dexlansoprazole MR achieved non-inferiority to lansoprazole, allowing testing for superiority. Using life-table analysis, dexlansoprazole MR healed 92-95% of patients in individual studies vs. 86-92% for lansoprazole; the differences were not statistically significant (P > 0.025). Using crude rate analysis, dexlansoprazole MR 90 mg was superior to lansoprazole in both studies and 60 mg was superior in one study. Week 4 healing was > 64% with all treatments in both studies. In an integrated analysis of 8-week healing in patients with moderate-to-severe EO, dexlansoprazole MR 90 mg was superior to lansoprazole. All treatments effectively relieved symptoms and were well tolerated. CONCLUSION Dexlansoprazole MR is highly effective in healing EO and offers benefits over lansoprazole, particularly in moderate-to-severe disease.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GERD) is a common disorder associated with substantial reductions in health-related quality of life (HRQL). AIM To describe patterns of change in HRQL during 5 years of follow-up in a large population of GERD patients. METHODS In 2000, a total of 6215 GERD patients were enrolled in the Progression of GERD (ProGERD) study. During follow-up, patients received any medication considered necessary. HRQL was assessed yearly with the Short-Form 36 and the Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaires. Associations between patient characteristics and changes in HRQL were analysed using multiple logistic regression models. RESULTS After 5 years, data on HRQL were available for 4597 (74%) patients. Both generic and disease-specific HRQL improved after baseline and remained well above baseline levels in the following years. A clinically relevant decrease in QOLRAD scores was reported by 3-5% of patients. According to our multivariate analysis, a decrease in HRQL was associated with a higher reflux symptom load and the presence of night-time heartburn. CONCLUSIONS Only a small minority of the ProGERD population reported a clinically relevant decrease in HRQL, which was associated most strongly with nocturnal heartburn.

Abstract
The prevalence of gastroesophageal reflux disease (GERD) ranges from 2.5% to 7.1% in most population-based studies in Asia. There is evidence that GERD and its complications are rising, coinciding with a decline in Helicobacter pylori (H. pylori) infection. Asian GERD patients share similar risk factors and pathophysiological mechanisms with their Western counterparts. Possible causes for the lower prevalence of GERD include less obesity and hiatus hernia, a lesser degree of esophageal dysmotility, a high prevalence of virulent strains of H. pylori, and low awareness. Owing to the lack of precise translation for 'heartburn' in most Asian languages, reflux symptoms are often overlooked or misinterpreted as dyspepsia or chest pain. Furthermore, a symptom-based diagnosis with a therapeutic trial of the proton pump inhibitor (PPI) may be hampered by the high prevalence of H. pylori-related disease. The risk stratification for prompt endoscopy, use of a locally-validated, diagnostic symptom questionnaire, and response to H. pylori'test and treat' help improve the accuracy of the PPI test for diagnoses. PPI remain the gold standard treatment, and 'on-demand' PPI have been shown to be a cost-effective, long-term treatment. The clinical course of GERD is benign in most patients in Asia. The risk of progression from non-erosive reflux disease to erosive esophagitis is low, and treatment response to a conventional dose of PPI is generally higher. Although H. pylori eradication may lead to more resilient GERD in a subset of patients, the benefits of H. pylori eradication outweigh the risks, especially in Asian populations with a high incidence of gastric cancer.

Abstract
BACKGROUND Management strategies for gastro-oesophageal reflux disease (GERD) are often inconsistent with the proposition that it is a persistent or chronic disease. AIM To determine the persistence of reflux symptoms and complications associated with GERD. METHODS Systematic searches of Medline and EMBASE. RESULTS In longitudinal studies, 65% (95% CI 54-75%) of patients with complicated GERD and 70% (95% CI 57-83%) of patients with 'defined' GERD had persistent disease at follow-up, whereas 34% (95% CI 27-40%) with infrequent or mild reflux symptoms at baseline had persistent symptoms. Clinical trials of maintenance treatment for at least 6 months after healing of oesophagitis reported mean relapse rates of 75% (95% CI 68-82%) in patients taking placebo and 28% (95% CI 21-35%) in those taking proton pump inhibitors. Retrospective studies reported that 34-41% of individuals with GERD recalled experiencing their symptoms for >10 years. The prevalence of GERD is high (10-20%), whereas the incidence is low (4.5-19.6 cases per 1000 person-years), suggesting that GERD is likely to persist for at least 18 years. CONCLUSIONS Individuals with GERD have persistent reflux symptoms that merit management as a chronic disease; infrequent reflux symptoms are less likely to be chronic and may respond to different management strategies.

Abstract
BACKGROUND Gastrin and pepsinogens reflect the functional state of the gastric mucosa. AIM To evaluate whether serum gastrin and pepsinogens correlate with the different grades of severity of gastro-oesophageal reflux disease (GERD). METHODS In all, 388 patients with heartburn not taking any form of acid suppressive therapy were matched-controlled for age and gender and sub-classified into four groups: group 1 non-erosive reflux disease (NERD); group 2, erosive reflux disease (ERD) Los Angeles (LA) A and B, group 3, ERD LA C and D; group 4 Barrett's oesophagus (BO). Fasting serum was analysed for gastrin 17, pepsinogen I, pepsinogen II und Helicobacter pylori using specific EIA tests (GastroPanel; Biohit, Plc). STATISTICS Kruskal-Wallis test and analysis of variance. RESULTS There was a significant difference among the four groups with respect for pepsinogen I, but not for pepsinogen II, the pepsinogen I pepsinogen II ratio, H. pylori serology and gastrin levels. Pepsinogen I was the lowest in NERD and the highest in BO (median 91.6, mean +/- standard deviation 106.2 +/- 51.6 vs. median 114.7, mean +/- standard deviation 130.4 +/- 70.6; P = 0.046). Pepsinogen I levels were higher in H. pylori positive subjects. After adjusting for H. pylori status, the differences in pepsinogen I across patient groups were no longer statistically significant (P = 0.298). CONCLUSIONS Serum gastrin and pepsinogen I and II do not correlate with the different grades of severity of GERD. The non-invasive GastroPanel is not useful for the differentiation of the various forms of GERD.

Abstract
Recent milestones in the understanding of gastric acid secretion and treatment of acid-peptic disorders include the (1) discovery of histamine H(2)-receptors and development of histamine H(2)-receptor antagonists, (2) identification of H(+)K(+)-ATPase as the parietal cell proton pump and development of proton pump inhibitors, and (3) identification of Helicobacter pylori as the major cause of duodenal ulcer and development of effective eradication regimens. This review emphasizes the importance and relevance of gastric acid secretion and its regulation in health and disease. We review the physiology and pathophysiology of acid secretion as well as evidence regarding its inhibition in the management of acid-related clinical conditions.
