J Clin Med 2022; 11:jcm11175224. [PMID: 36079155 PMCID: PMC9456826 DOI: 10.3390/jcm11175224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 08/29/2022] [Accepted: 09/02/2022] [Indexed: 11/25/2022] Open
Abstract
Background and Objective: To assess whether the combination of high waist-to-hip ratio (WHR) and elderly age is associated with higher risk of GERD. Material and Methods: A total of 16,996 subjects aged ≥20 years who received esophagogastroduodenoscopy (EGD) between January 2010 and December 2019. We evaluated the risk of GERD in different age groups and WHR groups in unadjusted analysis and multivariate logistic regression models for predictors of GERD. Results: There was a trend towards more participants with both age ≥65 years and WHR ≥ 1 (n = 129) (n = 66, 51%) than participants with age < 65 and WHR < 0.9 (n = 10,422) (n = 2814, 27%) presenting with GERD. Participants who had both age ≥ 65 years and high WHR ≥ 1 had the highest risk of any type of GERD (adjusted OR, 2.07; 95% CI, 1.44−2.96, p value < 0.05) based on multivariate logistic regression analysis. Conclusions: The combination of having a high WHR and being elderly was associated with a higher risk of GERD, and preventing central obesity in the elderly population reduced the risk of GERD and the requirement for medical resources.

Abstract
Background: Shankha bhasma is widely used in the treatment of gastroesophageal reflux disease (GERD) patients. Aim: To compare the efficacy of two purification methods of shankha bhasma in relieving GERD symptoms. In method A, purification was done with lemon juice and method B with sour gruel. Materials and Methods: Patients with heartburn since at least four days/week but who did undergo endoscopy to assess esophageal mucosa could participate. In this single-phase, single-center, prospective, randomized control trial, the patients were randomized to receive either shankha bhasma purified by method A or by method B. The primary efficacy variable was the proportion of patients with resolution of heartburn at week 4 and week 8. Design: Single-phase, single-center, prospective, randomized control trial in a hospital setting. Results: Of the total 70 patients who received samples A and B in a randomized double-blind manner, 65% of the patients showed resolution of symptoms in sample A and 28% in sample B at the end of four weeks, whereas, 71% of the patients showed resolution of symptoms in sample A and 31% in sample B at the end of eight weeks; P value was statistically significant for resolution of symptoms (P <0.005). Conclusion: Purification of shankha bhasma by lemon juice method is better than sour gruel method in terms of clinical outcome in GERD patients and is hence recommended.

Abstract
Histamine is a potent biogenic amine that mediates numerous physiological processes throughout the body, including digestion, sleep, and immunity. It is synthesized by gastric enterochromaffin-like cells, a specific set of hypothalamic neurons, as well as a subset of white blood cells, including mast cells. Much remains to be learned about these varied histamine-producing cell populations. Here, we report the validation of a transgenic mouse line in which Cre recombinase expression has been targeted to cells expressing histidine decarboxylase (HDC), which catalyzes the rate-limiting step in the synthesis of histamine. This was achieved by crossing the HDC-Cre mouse line with Rosa26-tdTomato reporter mice, thus resulting in the expression of the fluorescent Tomato (Tmt) signal in cells containing Cre recombinase activity. As expected, the Tmt signal co-localized with HDC-immunoreactivity within the gastric mucosa and gastric submucosa and also within the tuberomamillary nucleus of the brain. HDC expression within Tmt-positive gastric cells was further confirmed by quantitative PCR analysis of mRNA isolated from highly purified populations of Tmt-positive cells obtained by fluorescent activated cell sorting (FACS). HDC expression within these FACS-separated cells was found to coincide with other markers of both ECL cells and mast cells. Gastrin expression was co-localized with HDC expression in a subset of histaminergic gastric mucosal cells. We suggest that these transgenic mice will facilitate future studies aimed at investigating the function of histamine-producing cells.

ARQUIVOS DE GASTROENTEROLOGIA 2012; 49:107-12. [PMID: 22766996 DOI: 10.1590/s0004-28032012000200003] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2009] [Accepted: 09/21/2011] [Indexed: 02/06/2023]
Abstract
CONTEXT Esophageal pH monitoring is considered to be the gold standard for the diagnosis of gastroesophageal acid reflux. However, this method is very troublesome and considerably limits the patient's routine activities. Wireless pH monitoring was developed to avoid these restrictions. OBJECTIVE To compare the first 24 hours of the conventional and wireless pH monitoring, positioned 3 cm above the lower esophageal sphincter, in relation to: the occurrence of relevant technical failures, the ability to detect reflux and the ability to correlate the clinical symptoms to reflux. METHODS Twenty-five patients referred for esophageal pH monitoring and with typical symptoms of gastroesophageal reflux disease were studied prospectively, underwent clinical interview, endoscopy, esophageal manometry and were submitted, with a simultaneous initial period, to 24-hour catheter pH monitoring and 48-hour wireless pH monitoring. RESULTS Early capsule detachment occurred in one (4%) case and there were no technical failures with the catheter pH monitoring (P = 0.463). Percentages of reflux time (total, upright and supine) were higher with the wireless pH monitoring (P < 0.05). Pathological gastroesophageal reflux occurred in 16 (64%) patients submitted to catheter and in 19 (76%) to the capsule (P = 0.355). The symptom index was positive in 12 (48%) patients with catheter pH monitoring and in 13 (52%) with wireless pH monitoring (P = 0.777). CONCLUSIONS 1) No significant differences were reported between the two methods of pH monitoring (capsule vs catheter), in regard to relevant technical failures; 2) Wireless pH monitoring detected higher percentages of reflux time than the conventional pH-metry; 3) The two methods of pH monitoring were comparable in diagnosis of pathological gastroesophageal reflux and comparable in correlating the clinical symptoms with the gastroesophageal reflux.

Abstract
BACKGROUND Dexlansoprazole MR, a modified-release formulation of dexlansoprazole, an enantiomer of lansoprazole, effectively heals erosive oesophagitis. AIM To assess dexlansoprazole MR in maintaining healed erosive oesophagitis. METHODS Patients (n = 451) with erosive oesophagitis healed in either of two dexlansoprazole MR healing trials randomly received dexlansoprazole MR 60 or 90 mg or placebo once daily in this double-blind trial. The percentage of patients who maintained healing at month 6 was analysed using life table and crude rate methods. Secondary endpoints were percentages of nights and of 24-h days without heartburn based on daily diaries. RESULTS Dexlansoprazole MR 60 and 90 mg were superior to placebo for maintaining healing (P < 0.0025). Maintenance rates were 87% and 82% for the 60 and 90 mg doses, respectively, vs. 26% for placebo (life table), and 66% and 65% vs. 14%, respectively (crude rate). Both doses were superior to placebo for the percentage of 24-h heartburn-free days (60 mg, 96%; 90 mg, 94%; placebo, 19%) and nights (98%, 97%, and 50%, respectively). Diarrhoea, flatulence, gastritis (symptoms) and abdominal pain occurred more frequently with dexlansoprazole MR than placebo, but were not dose-related. CONCLUSION Dexlansoprazole MR effectively maintained healed erosive oesophagitis and symptom relief compared with placebo, and was well tolerated.

Abstract
BACKGROUND Dexlansoprazole MR heals all grades of erosive oesophagitis (EO). AIM To assess efficacy and safety of dexlansoprazole MR in maintaining healed EO and heartburn relief. METHODS In this randomized, double-blind trial, 445 patients with healed EO received dexlansoprazole MR 30 mg or 60 mg or placebo once daily for 6 months. This trial assessed maintenance of endoscopic healing (primary endpoint) and continued symptom relief based on daily diaries (secondary endpoints). RESULTS Dexlansoprazole MR 30 mg and 60 mg were superior to placebo for maintaining healed EO (P < 0.0025; Hochberg's). By life-table analysis, maintenance rates were 75%, 83% and 27% for dexlansoprazole MR 30 mg, 60 mg and placebo respectively. Crude maintenance rates were 66% for both dexlansoprazole MR doses and 14% for placebo. Dexlansoprazole MR controlled heartburn (medians of 91-96% for 24-h heartburn-free days, 96-99% for heartburn-free nights). The only more common adverse event occurring at a significantly higher rate in dexlansoprazole MR groups than placebo when analysed per patient-months of exposure was upper respiratory tract infection. CONCLUSIONS Dexlansoprazole MR effectively maintained EO healing and symptom relief; most patients were heartburn-free for >90% of days. Both doses were well tolerated.

Abstract
Gastroesophageal reflux disease (GERD) is a chronic disease affecting up to 40% of people in the Western world. Risk factors associated with GERD include age and lifestyle habits, although the clinically relevant contribution of many of these factors is unclear. In GERD, refluxed gastric acid damages the oesophageal mucosa, generally when the pH falls below 4. GERD patients present a variety of symptoms, most commonly heartburn and regurgitation. Oesophageal complications associated with GERD include erosions, ulcers, peptic strictures, and Barrett's oesophagus which is implicated in the development of oesophageal adenocarcinoma. Diagnosis of GERD is problematic due to the range of symptoms which may be presented to the physician and symptom severity is frequently unrelated to disease severity. While endoscopic monitoring may be used to assess the presence and severity of GERD, a lack of visible damage does not necessarily indicate an absence of GERD. Techniques used to diagnose GERD include addition of an acid solution into the oesophagus in order to replicate symptoms (Bernstein test) or 24-hour intra-oesophageal pH monitoring. Proton pump inhibitors are effective in the treatment of GERD, acting to reduce the acidity of the gastric juice and hence reduce oesophageal damage and symptoms associated with GERD. Symptoms most indicative of GERD are those associated with erosive oesophagitis, including heartburn and acid regurgitation. Less common GERD-associated symptoms include chest pain, a range of ear, nose and throat conditions, and asthma. In contrast to perceptions of the disease as 'merely' heartburn, the impact on patients' quality of life can be profound. Increasing awareness of GERD by health care professionals has led to improved diagnosis and a greater appreciation of the need for maintenance therapy.

Abstract
BACKGROUND Some patients requiring acid suppression may be unable to take oral medications. AIM To compare the gastric acid inhibition effects of lansoprazole 30 mg administered either intravenous or orally in erosive oesophagitis patients. METHODS The study included 87 Helicobacter pylori-negative patients with erosive oesophagitis. Each patient received 7 days of lansoprazole 30 mg orally prior to being randomized in a 3:1 fashion to intravenously lansoprazole 30 mg or intravenously placebo for 7 days. Basal acid output and pentagastrin-stimulated acid output were measured on days 8, 9 and 15. RESULTS Median pentagastrin-stimulated acid output was 7.2 mmol/h after 7 days of oral lansoprazole. The median pentagastrin-stimulated acid output increased to 7.6 mmol/h after 7 days of intravenous lansoprazole compared with 26.9 mmol/h after intravenous placebo (P < 0.001). CONCLUSIONS Lansoprazole 30 mg administered intravenous was equivalent to the 30 mg oral capsule in gastric acid suppression. Intravenous proton pump inhibitor therapy represents an important treatment option for those with acid-related diseases who are unable to take oral medications.

Abstract
Symptoms of gastro-oesophageal reflux disease are highly prevalent in Western countries; however, it is less certain how many individuals with heartburn have clinically relevant disease. Although the prevalence of gastro-oesophageal reflux disease in Asia is substantially lower, the incidence may be increasing. How much of this increase is explained by the increasing recognition of heartburn in clinical practice, dietary changes and increasing obesity, or the eradication of Helicobacter pylori, remains unclear. There has been speculation that endoscopy-negative reflux disease represents a separate entity from reflux oesophagitis (as defined by the Los Angeles classification), but the evidence that might support this proposal is unconvincing. Patients with chronic reflux symptoms have a higher risk of Barrett's oesophagus, and the increased risk of developing oesophageal adenocarcinoma in individuals with a long history of heartburn is also well documented, but whether this always occurs via Barrett's oesophagus is debatable. Moreover, treatment with standard-dose antisecretory therapies and anti-reflux surgery seems unlikely, based on current evidence, to reduce the cancer risk in patients with Barrett's oesophagus. Gastro-oesophageal reflux disease has also been implicated in an increasing array of other conditions, but arguably in these settings it is often over-diagnosed.

Abstract
BACKGROUND & AIMS Gastroesophageal reflux disease is common in adults of all ages, but its complications are more frequent in elderly patients. Although heartburn is the most common symptom of reflux disease, it is unclear whether the severity of heartburn reliably indicates the severity of erosive esophagitis. We therefore assessed the relationship between age, severe heartburn symptoms, and severe erosive esophagitis. METHODS This post hoc analysis of baseline data on the severity of both heartburn and erosive esophagitis pooled data from 5 prospective, randomized, controlled clinical trials that assessed the effect of proton pump inhibitors on healing of erosive esophagitis and symptom resolution. The clinical trials were conducted in 683 private and academic offices and hospital-based gastroenterology practices and involved 11,945 patients aged 18 years and older with gastroesophageal reflux disease and erosive esophagitis. RESULTS A progressive increase in the prevalence of severe erosive esophagitis was observed with each decade of age, ranging from 12% in patients aged <21 years to 37% in patients aged >70 years. Among patients with severe esophagitis, severe heartburn was less frequent in the older age groups: ranging from 82% of patients aged <21 years to 34% of those aged >70 years. Each of these associations was statistically significant (P < 0.001). CONCLUSIONS Although the prevalence of severe erosive esophagitis increases with age, the severity of heartburn is an unreliable indicator of the severity of erosive disease. More aggressive investigation and treatment may be necessary for elderly patients, regardless of the reported severity of heartburn.

Abstract
BACKGROUND Postgastrectomy patients often experience reflux esophagitis and a compromised quality of life. We hypothesized that reconstructive methods with antireflux procedures at operation should prevent reflux esophagitis and improve the likelihood of a better quality of life in patients after distal gastrectomy for gastric carcinoma. Our antireflux procedure was a subdiaphragmatic semifundoplication. We aim to substantiate, with objective arguments, potential advantages of Billroth I simple reconstruction versus Billroth I with semifundoplication. STUDY DESIGN This study evaluated 60 patients who had Billroth I reconstruction with semifundoplication (30 patients; F group) and simple Billroth I reconstruction (30 patients; B group) after distal gastrectomy for gastric cancer. Assessments were made preoperatively and 6 months or later after surgical intervention. Results of the procedure, clinical evaluation (reflux symptoms), and esophageal alkaline reflux by ambulatory 24-hour pH memory were satisfactory. RESULTS Operative evaluation time and procedural complications did not differ significantly between the two gastrectomy groups. Reflux symptoms only occurred in 12 patients in the B group. Lower esophageal sphincter pressure of patients in the B group was significantly lower than that of patients in the F group and in preoperative states (p < 0.05). The mean appearance of alkaline esophageal reflux in the F group and the B group were 2.6% and 13.6%, respectively (p < 0.01). Patients with semifundoplication had a significantly better quality of life and less physiologic regurgitation than patients with simple Billroth I. CONCLUSIONS This study demonstrated that Billroth I reconstruction with semifundoplication for gastric cancer is not only effective for patients with a postoperative life expectancy, but also prevents reflux esophagitis after gastrectomy. We believe that our method is an effective and simple surgical option for many patients with gastric cancer.

Abstract
OBJECTIVE The aim of this study was to determine the effect of 6-12 months of treatment with esomeprazole on the histopathology of the gastric mucosa. METHODS Two identically designed, randomized, placebo-controlled trials of esomeprazole 40, 20, or 10 mg daily for up to 6 months, as well as a noncomparative, multicenter trial of esomeprazole 40 mg daily for up to 12 months, were conducted in 1326 patients with healed erosive esophagitis (1294 negative for Helicobacter pylori [H. pylori]). Gastric biopsy samples were obtained before treatment and on completion of (or discontinuation from) the trials. Samples were evaluated for the presence of H. pylori, characteristics of acute gastritis or atrophic gastritis, and enterochromaffin-like cell pathology. RESULTS During treatment with esomeprazole, the number of patients with an improvement in gastric histological scores was typically greater than or equal to the number who worsened. Gastric histological scores worsened for each corporal or antral characteristic of gastritis in <6.2% of patients. Histological scores with esomeprazole and placebo were similar throughout the 6-month trials. Only one among 1326 patients treated with esomeprazole (H. pylori negative) had evidence of treatment-emergent atrophic gastritis. On final biopsy, 5-12% of patients had abnormal enterochromaffin-like cell scores (simple, linear, or micronodular hyperplasia). There were no instances of enterochromaffin-like cell dysplasia, carcinoids, or neoplasia. CONCLUSIONS Patients with healed erosive esophagitis receiving esomeprazole for up to 12 months had minor fluctuations in gastric histological scores, similar to those experienced in untreated populations. Use of esomeprazole did not raise any safety concerns with respect to the development of atrophic gastritis, or cause clinically significant changes in enterochromaffin-like cells.

Abstract
BACKGROUND The acid suppressive effect of lansoprazole is influenced by the P450 2C19 (CYP2C19) polymorphism. AIM To investigate whether the CYP2C19 genotype is related to the healing of erosive reflux oesophagitis during treatment with lansoprazole. METHODS Eighty-eight Japanese patients with erosive reflux oesophagitis were treated with a daily oral dose of 30 mg lansoprazole for 8 weeks. The CYP2C19 genotype, Helicobacter pylori infection status and serum pepsinogen I/II ratio were assessed before treatment. At 4 and 8 weeks, the healing of erosive reflux oesophagitis was evaluated endoscopically. RESULTS The healing rates were 57.1%, 69.2% and 72.7% at 4 weeks and 77.4%, 95.0% and 100% at 8 weeks in homozygous extensive metabolizers, heterozygous extensive metabolizers and poor metabolizers, respectively. At 8 weeks, the healing rate of erosive reflux oesophagitis was significantly lower in homozygous extensive metabolizers than in the other two groups (P < 0.05). The H. pylori status and serum pepsinogen I/II ratio had less influence than CYP2C19 polymorphism on the healing rate of erosive reflux oesophagitis. CONCLUSIONS The therapeutic effect of lansoprazole on erosive reflux oesophagitis is influenced by the CYP2C19 genotype status. Therefore, a test of CYP2C19 genotype may be useful for the medical treatment of reflux oesophagitis with lansoprazole.

Abstract
Gastro-oesophageal reflux disease (GORD) is common in the general population and is diagnosed based on patient-reported symptoms and clinical tests. Although clinical tests are available, significant percentages of patients report symptoms of heartburn and reflux despite negative endoscopies, and 24-hour pH tests are not often used by primary-care physicians in diagnosis. Consequently, patient-reported symptoms and health-related QOL (HR-QOL) are important in assessing treatment outcome. HR-QOL is significantly impaired in patients with GORD, and HR-QOL is associated with symptom severity and changes in GORD-related symptoms. The objective of this literature review is to examine the impact of pharmacological treatment on HR-QOL in patients with GORD. Generic and disease-specific HR-QOL measures have been used in clinical trials to evaluate the impact of GORD on patient functioning and well-being. The Psychological General Well-Being (PGWB) Index and the 36-Item Short-Form Health Survey (SF-36) have been used in several clinical trials of treatment for GORD and have consistently shown that HR-QOL improves with successful therapy. These trials have been conducted primarily with two pharmacological agents, omeprazole and ranitidine. On the Heartburn-specific Quality of Life questionnaire, patients treated with ranitidine reported better HR-QOL after treatment compared with placebo therapy. In two clinical trials where omeprazole and ranitidine were compared, patients treated with omeprazole reported significantly better HR-QOL (based on the PGWB Index) than those treated with ranitidine; however, 2 other trials did not detect significant differences between the treatments. Results from clinical trials using disease-specific measures (Gastrointestinal Quality of Life Index [GIQLI] and Heartburn-specific Quality of Life questionnaire) demonstrate similar findings, supporting the association between treatment-related symptom resolution and improvements in HR-QOL. The GIQLI was used in a trial comparing pantoprazole and ranitidine, where results favoured pantoprazole therapy. Several studies have demonstrated that resolution of GORD symptoms is associated with improvement in HR-QOL. Although there is evidence that treatment for GORD does improve symptoms and HR-QOL outcomes, further research is needed to more completely understand the value of medical therapy for GORD.

Abstract
Gastroesophageal reflux disease is a common illness that requires continuous and potentially long-term therapy. Current therapies include long-term acid-reducing medications (most commonly proton pump inhibitors), laparoscopic and open antireflux surgery, and most recently, endoscopic therapies. For the majority of patients with symptomatic GERD, long-term acid-reduction medications are standard therapy. However, endoscopic therapies offer an exciting new avenue for both research and clinical application in persons with gastroesophageal reflux disease. The role of endoscopic therapy in the management of patients with gastroesophageal reflux is still unclear at this time. Its major advantage will be for patients who do not desire long-term medical therapy, particularly those who are on fixed incomes and do not have prescription coverage. The mechanisms by which endoscopic antireflux treatment is effective at this time are uncertain at this time but likely involve a decrease in transient lower esophageal sphincter relaxations that result in decreased acid reflux and potentially in reduced acid sensory stimulation. The anticipated benefits from endoscopic therapy are discontinuance of medications in 30% to 50% of patients at 2 years posttreatment, a reduction in medication use in another 10% to 15% of patients, and avoidance of disruption of the antireflux barrier. The long-term durability of endoscopic treatment is still unknown, although 2-year data appear promising. The role of endoscopic therapy in the treatment of patients with modest hiatal hernias, delayed gastric emptying, atypical symptoms of gastroesophageal reflux, and failed Nissen fundoplication with documented postprocedure reflux remains unclear and requires further study.

Abstract
OBJECTIVE To evaluate the safety and tolerability of long term treatment with esomeprazole in patients with healed erosive oesophagitis, and to describe its efficacy in the maintenance of healing. DESIGN AND SETTING US multicentre, noncomparative, nonblind study. PATIENTS AND PARTICIPANTS 807 patients with endoscopically confirmed healed erosive oesophagitis. METHODS Patients received esomeprazole 40 mg once daily for up to 12 months. Adverse events and clinical laboratory tests were assessed over the study period. Endoscopy was performed at the final visit of the antecedent healing trials and at months 6 and 12 of the current safety trial; gastric biopsies were obtained at the initial visit of the healing trials and at the end of the safety trial. RESULTS 80.9% of patients completed 6 months of treatment; 76.6% completed 12 months of treatment. There were no serious drug-related adverse events. Diarrhoea, abdominal pain, flatulence, and headache were the only treatment-related adverse events reported by >3% of patients. Mean changes in laboratory measures were generally small and not clinically meaningful. Plasma gastrin levels increased, as expected, and reached a plateau after 3 months. No changes in gastric histological scores were noted in the majority of patients. Evaluation of gastric biopsies revealed an overall decline in chronic inflammation and atrophy. Intestinal metaplasia findings remained essentially unchanged. Life table estimates of maintenance of healing were 93.7% [95% confidence interval (CI) 92.0 to 95.5%] at 6 months and 89.4% (95% CI 87.0 to 91.7%) at 12 months. CONCLUSIONS Daily treatment with esomeprazole 40 mg for up to 1 year in patients with healed erosive oesophagitis was generally well tolerated and effective. No safety concerns arose.

Abstract
BACKGROUND Postural measures are early recommendations in the management of heartburn, and are aimed at preventing acid reflux through an incompetent lower esophageal sphincter (LES). However, LES incompetence is found in only a minority of patients, and transient LES relaxations, primarily in the upright position, are currently recognized as the main pathophysiological abnormality in gastroesophageal reflux disease (GERD). We investigated the importance of supine acid reflux in patients with GERD. METHODS Upon review of their clinical, manometric, pH monitoring and endoscopic characteristics, 85 patients with reflux symptoms were classified into three groups: Group A (n=22), consisting of symptomatic patients without esophagitis or pathological reflux; group B (n=38), symptomatic patients with reflux but no endoscopic esophagitis; and group C (n=25), symptomatic patients with both ulcerative or complicated esophagitis and pathological reflux. RESULTS All groups were similar in age distribution. Groups B and C had a higher prevalence of hiatal hernia and reflux symptoms. Manometry revealed similar LES pressures in groups A and B, but lower LES pressure in group C (P < 0.005). In groups A and B, supine reflux, in terms of percentage of time with pH < 4, was less pronounced than upright reflux (P < 0.0001). In contrast, group C supine reflux was as pronounced as the upright reflux. CONCLUSIONS The majority of patients reflux in the upright position. Only patients with complicated esophagitis have significant bipositional acid reflux. These findings suggest that unless the patient has severe reflux disease, postural measures may not be indicated.

Abstract
OBJECTIVE This randomized, double-blind, multicenter study was conducted to confirm a previous finding that lansoprazole relieves heartburn faster than omeprazole in patients with erosive esophagitis. METHODS A total of 3510 patients with erosive esophagitis and at least one episode of moderate to very severe daytime and/or nighttime heartburn during the 3 days immediately before the screening visit were randomized to lansoprazole 30 mg once daily or omeprazole 20 mg once daily for 8 wk. Patients recorded the presence and severity of daytime and nighttime heartburn in daily diaries. On treatment days 1-4, patients were telephoned to confirm the completion of their daily diary. The primary efficacy parameters were the percentage of heartburn-free days and heartburn-free nights, as well as the average severity of daytime and nighttime heartburn. RESULTS During treatment day I and all evaluation time points including the entire 8-wk treatment period, significantly (p < 0.05) higher percentages of patients treated with lansoprazole than those treated with omeprazole did not experience a single episode of heartburn. Onset of heartburn relief was more rapid in lansoprazole-treated versus omeprazole-treated patients: on day 1, 33% versus 25% of lansoprazole- versus omeprazole-treated patients were heartburn-free. The percentages of heartburn-free days and heartburn-free nights were also significantly (p < 0.01) greater for patients treated with lansoprazole at all evaluation time points. Heartburn severity was significantly less among those treated with lansoprazole compared with omeprazole. Both treatments were safe and well tolerated. CONCLUSIONS Over 8 wk, lansoprazole 30 mg once daily relieved heartburn symptoms faster and more effectively than omeprazole 20 mg once daily in patients with erosive esophagitis.

Abstract
One hundred and twenty-two patients with gastroesophageal reflux disease were studied (90 with and 32 without esophagitis) with the objective of analyzing possible differences between those with and without esophagitis. Evaluation consisted of clinical interview, endoscopy of the high digestive tract, esophageal manometry, and pH monitoring. There was no significant difference between the groups in age, sex, or symptoms. The incidence of hiatal hernia was greater in the group with esophagitis. Although the frequency of motor changes was similar, the type of anomaly was different. The reflux pattern was very similar in both groups. Therefore, the concept of reflux disease, esophagitis, and pathological reflux still needs a broader definition for greater diagnostic precision and for comparing the results of different studies on the subject. Normal reflux (confirmed using pH esophageal monitoring) in 12.2% of patients with esophagitis suggests that other factors are implicated in the etiology of the disease besides those measured using this examination.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition with a variety of clinical manifestations and potentially serious complications. This article reviews available methods for diagnosing GERD. A clinical history of the classic symptoms of GERD, heartburn or acid regurgitation, is sensitive enough to establish the diagnosis in patients without other complications. Esophagogastroduodenoscopy is the best way to evaluate suspected complications of GERD, but endoscopic findings are insensitive for the presence of pathological reflux, and therefore they cannot reliably exclude GERD. The "gold standard" study for confirming or excluding the presence of abnormal gastroesophageal reflux is the 24-hour ambulatory esophageal pH monitoring test, and this study should be used for the evaluation of refractory symptoms and extraesophageal manifestations of GERD. A formal acid-suppression test is helpful in the evaluation of the atypical GERD symptom of noncardiac chest pain. Optimal use of currently available tests for GERD may allow for more efficient diagnosis and better characterization of the pathological manifestations associated with GERD.

Abstract
BACKGROUND The pharmacologic profile of the new proton pump inhibitor esomeprazole has demonstrated advantages over omeprazole that suggest clinical benefits for patients with acid-related disease. METHODS 1960 patients with endoscopy-confirmed reflux oesophagitis (RO) were randomized to once daily esomeprazole 40 mg (n=654) or 20 mg (n=656), or omeprazole 20 mg (n=650), the standard recommended dose for RO, for up to 8 weeks in a US, multicentre, double-blind trial. The primary efficacy variable was the proportion of patients healed at week 8. Secondary variables included healing and heartburn resolution at week 4, time to first resolution and sustained resolution of heartburn, and per cent of heartburn-free days and nights. Safety and tolerability were also evaluated. RESULTS Significantly more patients were healed at week 8 with esomeprazole 40 mg (94.1%) and 20 mg (89.9%) vs. omeprazole 20 mg (86.9%), using cumulative life table estimates, ITT analysis (each P < 0.05). Esomeprazole 40 mg was also significantly more effective than omeprazole for healing at week 4 and for all secondary variables evaluating heartburn resolution. The most common adverse events in all treatment groups were headache, abdominal pain and diarrhoea. CONCLUSION Esomeprazole was more effective than omeprazole in healing and symptom resolution in GERD patients with reflux oesophagitis, and had a tolerability profile comparable to that of omeprazole.

Abstract
Gastroesophageal reflux has been implicated in the pathogenesis of a wide variety of otolaryngologic disorders. Patients with otolaryngologic disorders associated with gastroesophageal reflux infrequently have the classic symptoms of gastroesophageal reflux, such as heartburn. Clinical presentation of laryngopharyngeal reflux is commonly characterized by chronic intermittent symptoms. A meticulous synthesis of the information obtained from a complete otolaryngologic examination, diagnostic tests, and response to treatment is essential for the efficient management of patients with otolaryngologic disorders associated with laryngopharyngeal reflux.

Abstract
BACKGROUND An endoscopic technique that eliminates gastroesophageal reflux disease would be of benefit to patients. The endoscopic delivery of radiofrequency energy to the porcine gastroesophageal junction was investigated and its effect on lower esophageal sphincter pressure, gastric yield pressure, and histology was assessed. METHODS Twenty pigs underwent esophageal manometry and endoscopic injection of botulinum toxin (100 units) into the lower esophageal sphincter. After 1 week, animals were randomized to radiofrequency energy treatment of the gastroesophageal junction with a 4- needle catheter and thermocouple-controlled generator (n = 13) or no further intervention (control, n = 7). At 9 weeks, animals underwent esophagoscopy, manometry, gastric yield pressure determination, and sacrifice for histopathologic evaluation. RESULTS Mean lower esophageal sphincter pressure declined by 3.7 +/- 2.6 mm Hg (control, p = 0.03) vs. 0.97 +/- 5.8 mm Hg (radiofrequency, p = 0.29) after 9 weeks. Mean gastric yield pressure was 24.9 +/- 8.2 mm Hg (control), compared with 43.4 +/- 10. 7 mm Hg (radiofrequency) (p = 0.0007). Histopathologic assessment demonstrated normal mucosa, mild fibrosis, and no inflammation. CONCLUSIONS Radiofrequency energy delivery reversed much of the lower esophageal sphincter pressure reduction achieved with botulinum toxin injection and augmented gastric yield pressure by 75% compared with controls. Given the safety of radiofrequency energy delivery in this study and in other areas of medicine, human studies to assess the effect of radiofrequency energy on gastroesophageal reflux disease are warranted.

Abstract
BACKGROUND H2-receptor antagonists are widely used in patients with gastro-oesophageal reflux disease (GERD) and are frequently continued when symptoms persist. AIM To compare the efficacy of omeprazole 20 mg once daily with that of ranitidine 150 mg twice daily in relieving GERD symptoms, in patients who remained symptomatic following a 6-week course of ranitidine therapy. METHODS Patients with heartburn on at least 4 days/week but who did not have endoscopy to assess oesophageal mucosa could participate. This two-phase, prospective trial included a 6-week open-label phase (phase I), followed by an 8-week double-blind phase (phase II). Patients still symptomatic following treatment with ranitidine 150 mg twice daily (phase I) were randomized to double-blind treatment (phase II) with either omeprazole 20 mg once daily or ranitidine 150 mg twice daily. The primary efficacy variable was the proportion of patients with heartburn resolution during weeks 4 and 8 of phase II. RESULTS Of the 533 patients with GERD who received ranitidine in phase I, 348 patients (65%) were still symptomatic. A total of 317 patients (59%) were randomized to double-blind treatment (phase II). At week 8, a significantly (P < 0.0004) greater proportion of omeprazole-treated patients (70%) experienced no more than mild heartburn compared with ranitidine-treated patients (49%). Complete resolution of heartburn also occurred in a significantly (P < 0. 00001) greater proportion of omeprazole-treated patients (46% vs. 16% of the ranitidine group at week 8). CONCLUSIONS After 6 weeks of ranitidine treatment, the majority of patients with GERD were still experiencing moderate to severe heartburn. Omeprazole was significantly more effective than ranitidine in resolving heartburn in this group of patients.

Abstract
Gastroesophageal reflux disease (GERD) is a spectrum of disease that can best be defined as the symptoms and/or signs of esophageal or adjacent organ injury secondary to the reflux of gastric contents into the esophagus or, beyond, into the oral cavity or airways. Injury is defined based on symptoms or organ damage resulting in esophagitis, laryngeal inflammation, or acute and/or chronic pulmonary injury. Though specific studies are lacking, GERD seems to occur more frequently in older people. In general, because it has been present for a longer period of time, older patients will often present with more complicated GERD, including severe erosive esophagitis, peptic stricture, and Barrett's esophagus, a premalignant condition, making treatment of older patients with GERD potentially more difficult and complex. Though it is not usually life-threatening, GERD can have a major effect on patients' well-being and quality of life. This article reviews the presentation, pathophysiology, diagnosis, and treatment of GERD as it relates to the older patient.

Abstract
OBJECTIVE The utility of endoscopy in the management of patients with symptoms of gastroesophageal reflux disease (GERD) is unclear. The purpose of this prospective study was to assess the impact of endoscopy on the subsequent management of patients with uncomplicated reflux symptoms. METHODS A total of 742 patients underwent endoscopy for symptoms of GERD. Endoscopists recorded the therapy before endoscopy, the findings of endoscopy, and the treatment recommendations after endoscopy. RESULTS There was no difference in pre-endoscopy therapy or grade of esophagitis in subjects undergoing endoscopy for failed therapy versus GERD symptoms alone. After endoscopy, the most common strategy for patients taking omeprazole was to maintain or increase the dose. For those taking an H2 blocker before endoscopy, the most common outcome was to switch the patient to omeprazole, independent of the grade of esophagitis. CONCLUSIONS Most patients undergoing endoscopy for symptoms of GERD were switched to omeprazole regardless of the endoscopic findings. No esophageal cancer was identified and the incidence of Barrett's esophagus was low. It appears that endoscopy itself did not change the management of patients receiving H2-blocker therapy. A trial of a proton pump inhibitor before endoscopy should be considered.

Abstract
OBJECTIVE Using clinical practice guidelines, a registered nurse adjusted antireflux medications, evaluated esophageal biopsy reports, determined the interval between surveillance endoscopies, and provided education for patients with Barrett's esophagus. No previous reports have assessed the effectiveness or patient satisfaction associated with registered nurse-provided primary care. Because estimates of the incidence of dysplasia and adenocarcinoma vary widely, we also prospectively followed a cohort of patients with Barrett's esophagus. METHODS Charts were reviewed to determine the frequency of variation from guidelines, the annual incidence of dysplasia and adenocarcinoma, and frequency of reflux symptoms. Patients were mailed a questionnaire to assess satisfaction with their medical care and with the nurse. RESULTS Variation by the nurse from the guidelines on surveillance endoscopy (1.9%) and the treatment of reflux (1.3%) was rare. Most patients were very satisfied (score of 6 on 0-6-point Likert scale) with overall medical care (88%), and patient education (76%), and most patients did not think that increased physician involvement would improve their care (93%). Ninety-seven percent of patients had control of reflux symptoms. Two patients with long segment Barrett's esophagus (n = 67) developed high grade dysplasia over 323 patient-yr of follow-up (1 of 162 patient-yr for an annual incidence of 0.6%). No patients with short segment Barrett's esophagus (n = 56) developed high grade dysplasia or adenocarcinoma over 172 patient-years of follow-up. CONCLUSION The registered nurse in our clinical setting effectively administered clinical practice guidelines for the management of Barrett's esophagus without clinically significant morbidity or patient dissatisfaction. Before these results can be generalized to other settings, further studies will need to be performed.

BACKGROUND Gastroesophageal reflux disease (GERD) affects health-related quality of life. METHODS We enrolled 533 adults with a history of heartburn symptoms for at least 6 months of moderate to severe heartburn in 4 of the 7 days before study entry. Patients were treated with ranitidine 150 mg twice a day for 6 weeks and Gelusil antacid tablets as needed. We measured physician-rated symptoms and the Medical Outcomes Study short-form 36 (SF-36) Health Survey at baseline and after 6 weeks of treatment. Baseline results were compared with normative data for the US population and for patients with selected chronic diseases. Treatment response was defined as no episode of moderate to severe heartburn for 7 days. Statistical significance was set at P <0.001. RESULTS GERD patients reported significantly worse scores on all 8 SF-36 scales, physical function and well-being, and emotional well-being compared with the general population. Patients with GERD reported worse emotional well-being than patients with diabetes or hypertension. Treatment responders demonstrated significantly less pain and better physical function, social function, vitality, and emotional well-being compared with nonresponders. CONCLUSIONS Patients with GERD experience decrements in health-related quality of life compared with the general population. The impact of GERD is most striking on measures of pain, mental health, and social function. Successful treatment for GERD results in improvements in health-related quality of life.

Abstract
BACKGROUND Laparoscopic approach for hiatal hernia repair is relatively new. Information on the learning curve is limited. METHODS From January 1994 to September 1996, 280 patients underwent antireflux surgery at our institution. A laparoscopic repair was attempted in 60 patients (21.4%). There were 38 men and 22 women. Median age was 49 years (range 21 to 78 years). Indications for operation were gastroesophageal reflux in 59 patients and a large paraesophageal hernia in one. A Nissen fundoplication was performed in all patients; 53 (88.3%) had concomitant hiatal hernia repair. RESULTS In eight patients (13.3%) the operation was converted to an open procedure. Median operative time for the 52 patients who had laparoscopic repair was 215 minutes (range 104 to 320 minutes). There were no deaths. Complications occurred in five patients (9.6%). Median hospitalization was 2 days (range 1 to 5 days). Median operative time and median hospitalization were significantly longer in the first 26 patients than in the subsequent 25 patients (248 vs 203 minutes and 2 days vs 1 day, respectively; p = 0.03). Seven of the first 30 patients (23.3%) required laparotomy as compared with two of the second 30 (6.7%) (p = 0.07). Follow-up in the 51 patients who had laparoscopic fundoplication for reflux was complete in 50 (98.0%) and ranged from 7 to 38 months (median 13 months). Functional results were classified as excellent in 34 patients (68.0%), good in 6 (12.0%), fair in 7 (14.0%), and poor in 3 (6.0%). Three patients were reoperated on for recurrent reflux symptoms at 5, 5, and 11 months. CONCLUSIONS We conclude that laparoscopic Nissen fundoplication can be performed safely. The operative time, hospitalization, and conversion rate to laparotomy are higher during the early part of the experience, but all are reduced after the learning curve.

Abstract
Columnar-lined esophagus or Barrett's esophagus is closely associated with gastroesophageal reflux disease. Animal and human studies have shown not only acid but duodenogastroesophageal reflux acting in synergy with acid causes the most esophageal injury. Patients with Barrett's esophagus manifest typical and atypical symptoms of reflux. Ten percent to 25%, however, have clinically silent reflux. Early diagnosis is essential for this disease as it is a risk factor for the development of adenocarcinoma of the esophagus.

Abstract
GERD is a common disorder. Symptoms of reflux, such as heartburn, are due to a combination of factors: relaxation of the lower esophageal sphincter, hypersecretion of gastric acid, and resulting burning of the esophageal mucosa. Symptoms are usually classified as classic, atypical, or complicated. Treatment approaches include dietary and lifestyle changes, reduction of acidity with use of H2 receptor antagonists, and reduction of acid secretion with use of proton pump inhibitors. Patient motivation is an important factor in the management of gastroesophageal reflux. In rare instances, patients do not respond to medical treatment and are candidates for antireflux surgery.

Abstract
One thousand one hundred forty-five patients with acute erosive reflux esophagitis participating in an eight-week double-blind, multicenter study of lansoprazole 15 mg daily, lansoprazole 30 mg daily, omeprazole 20 mg daily, and placebo responded to a health-related quality of life (HRQoL) questionnaire at baseline and at two, four, and eight weeks. At baseline, there were no HRQoL differences among the four study groups. However, all three active treatment groups improved statistically significantly more than placebo on most HRQoL scales at each follow-up. There were no statistically significant differences among the three active treatment groups at week 2, although in most instances lansoprazole 30 mg showed slightly more improvement. After week 2, benefits in all the study groups leveled off and remained constant. Greater acid suppression appeared to result in greater improvement in terms of HRQoL.

Abstract
GERD is a common clinical problem. Generally, its clinical presentation and management are straightforward. Greater awareness of the numerous extraesophageal manifestations of the disease aids patients and physicians in appropriate recognition and treatment. Medical therapy is effective in the majority of cases but often requires long-term medication for acceptable symptom control. A small, but significant proportion of patients presents with or develops complications of GERD, most importantly Barrett's esophagus. Although the logistics of long-term surveillance of persons with Barrett's esophagus is unclear, the association of this metaplastic change with esophageal adenocarcinoma underscores the importance of regular follow-up.

Abstract
Gastroesophageal reflux (GER) is one of the most frequent symptomatic clinical disorders affecting the gastrointestinal tract of infants and children. During the past 2 decades, GER has been recognized more frequently because of an increased awareness of the condition and also because of the more sophisticated diagnostic techniques that have been developed for both identifying and quantifying the disorder. Gastroesophageal fundoplication is currently one of the three most common major operations performed on infants and children by pediatric surgeons in the United States. Normal gastroesophageal function is a complex mechanism that depends on effective esophageal motility, timely relaxation and contractility of the lower esophageal sphincter, the mean intraluminal pressure in the stomach, the effectiveness of contractility in emptying of the stomach, and the ease of gastric outflow. More than one of these factors are often abnormal in the same child with symptomatic GER. In addition, in patients with GER disease, and particularly in those patients with neurologic disorders, there appears to be a high prevalence of autonomic neuropathy in which esophagogastric transit and gastric emptying are frequently delayed, producing a somewhat complex foregut motility disorder. GER has a different course and prognosis depending on the age of onset. The incompetent lower esophageal sphincter mechanism present in most newborn infants combined with the increased intraabdominal pressure from crying or straining commonly becomes much less frequent as a cause of vomiting after the age of 4 months. Chalasia and rumination of infancy are self-limited and should be carefully separated from symptomatic GER, which requires treatment. The most frequent complications of recurrent GER in childhood are failure to thrive as a result of caloric deprivation and recurrent bronchitis or pneumonia caused by repeated pulmonary aspiration of gastric fluid. Children with GER disease commonly have more refluxing episodes when in the supine position, particularly during sleep. The reflux of acid into the mid or upper esophagus may stimulate vagal reflexes and produce reflex laryngospasm, bronchospasm, or both, which may accentuate the symptoms of asthma. Reflux may also be a cause of obstructive apnea in infants and possibly a cause of recurrent stridor, acute hypoxia, and even the sudden infant death syndrome. Premature infants with respiratory distress syndrome have a high incidence of GER. Esophagitis and severe dental carries are common manifestations of GER in childhood. Barrett's columnar mucosal changes in the lower esophagus are not infrequent in adolescent children with chronic GER, particularly when Heliobacter pylori is present in the gastric mucosa. Associated disorders include esophageal dysmotility, which has been recognized in approximately one third of children with severe GER. Symptomatic GER is estimated to occur in 30% to 80% of infants who have undergone repair of esophageal atresia malformations. Neurologically impaired children are at high risk for having symptomatic GER, particularly if nasogastric or gastrostomy feedings are necessary. Delayed gastric emptying (DGE) has been documented with increasing frequency in infants and children who have symptoms of GER, particularly those with neurologic disorders. DGE may also be a cause of gas bloat, gagging, and breakdown or slippage of a well-constructed gastroesophageal fundoplication. The most helpful test for diagnosing and quantifying GER in childhood is the 24-hour esophageal pH monitoring study. Miniaturized probes that are small enough to use easily in the newborn infant are available. This study is 100% accurate in diagnosing reflux when the esophageal pH is less than 4.0 for more than 5% of the total monitored time.
