Abstract
BACKGROUND Gastroesophageal Reflux Disease (GERD) is a prevalent condition in Brazil, affecting 12% to 20% of the urban population, with significant implications for patient quality of life and potential for complications. OBJECTIVE This paper focuses on the recent update of the Brazilian guidelines for GERD, a necessary revision due to advancements in knowledge and practice since the last publication over a decade ago. The update pays particular attention to the role and safety of proton pump inhibitors (PPIs), acknowledging the growing concerns about their long-term use, adverse events, and overprescription. METHODS The methodology of the guideline update involved an extensive literature review in multiple languages (English, French, Italian, Spanish, and Portuguese), drawing from major databases such as Medline, Embase, and SciELO-Lilacs. RESULTS This comprehensive approach resulted in a carefully curated selection of studies, systematic reviews, and meta-analyses, specifically focusing on PPIs and other therapeutic strategies for GERD. The updated guidelines are presented in a user-friendly question-and-answer format, adhering to the PICO system (Population, Intervention, Comparison, Outcomes) for clarity and ease of interpretation. The recommendations are supported by robust scientific evidence and expert opinions, enhancing their practical applicability in clinical settings. To ensure the reliability and clarity of the recommendations, the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation) was employed. This system categorizes the strength of recommendations as strong, weak, or conditional and classifies evidence quality as high, moderate, low, or very low. These classifications provide insight into the confidence level of each recommendation and the likelihood of future research impacting these guidelines. CONCLUSION The primary aim of these updated guidelines is to offer practical, evidence-based advice for the management of GERD in Brazil, ensuring that healthcare professionals are equipped with the latest knowledge and tools to deliver optimal patient care. BACKGROUND •Gastrointestinal specialists rely heavily on guidelines to manage digestive pathologies effectively. The Brazilian clinical guideline for therapeutic management of gastroesophageal reflux disease (GERD) is an invaluable tool for these specialists. BACKGROUND •It critically analyzes practical aspects of therapy through 12 questions covering a wide range of topics, from behavioral measures to surgical and endoscopic indications. BACKGROUND •The recommendations in this guideline are justified using the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation), and experienced experts provide comments and suggestions at the end of each question.

Abstract
BACKGROUND Heartburn and acid regurgitation are typical symptoms usually associated with gastroesophageal reflux disease (GERD). GERD is one of the gastrointestinal diagnosis with higher prevalence worldwide, significantly impairing patients' quality of life. OBJECTIVE The objective of this study was to analyze the impact of GERD-related symptoms in the Brazilian urban population. METHODS National telephone survey with community-dwelling Brazilian individuals. Self-reported prevalence and frequency of symptoms (heartburn / regurgitation) were assessed. Individuals rated the impact of symptoms in their general well-being using a numeric scale from 1 to 10 (1 = no impact; 10 = very intense, preventing the person to eat and perform daily routine activities). Descriptive and bivariate statistical analyses were performed. RESULTS The final sample was comprised of 1,773 subjects, 935 (52.7%) females, an average of 40 years old. The prevalence of heartburn and regurgitation in the past 6 months was 26.2% (n=466) and 11.0% (n=196), respectively. Women presented higher prevalence (heartburn n=266, 28.5% and regurgitation n=119, 12.7%) than men (n=200, 23.1% and n=78, 8.9%, respectively) (P<0.05). Heartburn in the past week was reported by 175 individuals (9.8%), while regurgitation episodes by 67 (3.8%). Absence of impact of the symptom in the overall well-being was observed for 82 subjects (17.6%) with heartburn and 18 individuals (9.2%) with regurgitation. Very intense impact was reported by 46 subjects (9.8%) with heartburn and 41 (20.9%) with regurgitation. Women's well-being was more affected than men's (mean score 5.45 vs 4.71, P<0.05). CONCLUSION Heartburn and regurgitation were frequent symptoms, women with higher prevalence. These symptoms led to a substantial impact on individuals' well-being, women being more affected.

Abstract
BACKGROUND Clinical guidelines are available to steer decisions regarding diagnosis, management and treatment of gastrointestinal disorders. Despite this, variations in physician's practices regarding gastroesophageal reflux disease (GERD) symptoms are well described in the literature. OBJECTIVE To describe practices of physicians from different specialties on the management of patients with typical symptoms of GERD (heartburn and regurgitation) in a Brazilian sample. METHODS National online survey enrolling a sample of general practitioners, gastroenterologists, cardiologists and otolaryngologists. The survey was conducted from August 6th to September 12th, 2018. Subjects answered a structured questionnaire addressing variables regarding physicians' profile (age, sex, specialty, practice setting, years in practice, type of medical expense reimbursement), their patients characteristics and prescribing behaviors. RESULTS The final weighted sample was comprised of 400 physicians, 64% male, with an average of 15 years of experience. Physicians' estimates of gastroesophageal symptoms prevalence among their pool of patients was 37.6% for the total sample, reaching 70.3% among gastroenterologists. The medical specialty with lower average percentage of patients presenting gastroesophageal symptoms was otolaryngology (24.5%). Physicians reported that they request ancillary tests for 64.5% of patients with GERD typical symptoms. The most common diagnostic test was endoscopy (69.4%), followed by video nasolaryngoscopy (16.6%). The percentage of patient to whom endoscopy is performed was significantly higher among gastroenterologists and general practitioners as compared to otolaryngologists and cardiologists, while video nasolaryngoscopy is markedly more frequent among otolaryngologists. In terms of therapeutic options, the most frequently reported strategy was lifestyle modifications followed by proton pump inhibitors. CONCLUSION Overall patients' profile and patterns of GERD diagnosis and management seem different between gastroenterologists, general practitioners, otolaryngologists, and cardiologists. Clinical guidelines should address this variability and include other medical specialties besides gastroenterologists in their scope.

Abstract
Gastroesophageal reflux disease (GERD) is a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Heartburn and regurgitation are the typical symptoms of GERD. The treatment of GERD encompasses lifestyle modifications, pharmacological, endoscopic, and surgical therapy. The majority of the patients respond to 4-8 weeks of proton-pump inhibitors therapy, but 20-42% will demonstrate partial or complete lack of response to treatment. While these patients have been considered as having refractory heartburn, a subset of them does not have GERD or have not been adequately treated. The main causes of refractory heartburn include: poor compliance; inadequate proton-pump inhibitors dosage; incorrect diagnosis; comorbidities; genotypic differences; residual gastroesophageal reflux; eosinophilic esophagitis and others. Treatment is commonly directed toward the underlying cause of patients' refractory heartburn.

Abstract
The basis of pharmacological treatment of the gastroesophageal reflux disease is the use of proton pump inhibitors (PPIs) which provide effective gastric acid secretion blockade. However, PPI therapy failure may occur in up to 42% of patients. The main causes for therapeutic failure are non-acid or weakly acid reflux, genotypic differences, presence of comorbidities, wrong diagnosis and lack of treatment compliance. Noncompliance is an important issue and should be carefully observed. Several studies addressed patient compliance and 20-50% of patients may present lack of compliance to the PPI prescribed. When symptoms persist depite adherence has been confirmed, it is recommended to substitute the prescribed PPI to another of the same class or alternatively, prescription of a double dose of the same drug. When even so the symptoms persist, other causes of failure should be assigned. In particular cases of PPI failure, fundoplication surgery may be indicated.

Abstract
CONTEXT Gastroesophageal reflux disease (GERD) is a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Its pathophysiology, diagnosis and treatment have frequently been analyzed but it is interesting to review some aspects of the GERD refractory patients to the proton pump inhibitors treatment. The treatment encompasses behavioral measures and pharmacological therapy. The majority of the patients respond well to proton pump inhibitors treatment but 20%-42% of them may not do so well. Patients who are unresponsible to 4-8 weeks' treatment with proton pump inhibitors (omeprazole, pantoprazole, rabeprazole, lansoprazole, esomeprazole, pantoprazole-Mg) might have so-called refractory GERD. RESULTS In some cases the patients are not real refractory because either they do not have GERD or the disease was not correctly treated, but the term refractory is still employed. Although debatable, the Brazilian GERD Consensus based upon evidences recommends as first step in the diagnosis, the upper digestive endoscopy to exclude the diagnosis of peptic ulcer and cancer and in some cases identify the presence of esophageal mucosa erosions. CONCLUSIONS The main causes of the so-called refractory GERD are: (1) functional heartburn; (2) low levels of adherence to proton pump inhibitors treatment; (3) inadequate proton pump inhibitors dosage; (4) wrong diagnosis; (5) co-morbidities and pill-induced esophagitis; (6) genotypic differences; (7) nonacid gastroesophageal reflux; (8) autoimmune skin diseases; (9) eosinophilic esophagitis.

Abstract
Signicant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

Abstract
CONTEXT The antibiotic susceptibility is the cornerstone for the eradication therapies of Helicobacter pylori. OBJECTIVES To evaluate the prevalence of primary resistance of H. pylori was evaluated in an urban Brazilian population. METHODS H. pylori isolates were obtained from patients submitted to an upper gastrointestinal endoscopy for the evaluation of dyspeptic symptoms. Biopsies from antrum, corpus and fundus were taken to determine the antibiotic susceptibility of H. pylori isolates. The minimal inhibitory concentration of furazolidone and bismuth were routinely determined by agar dilution method and the minimal inhibitory for amoxicillin, clarithromycin, tetracycline, levofloxacin, and metronidazole were routinely determined with the E-test. RESULTS Fifty-four patients were included. In vitro antimicrobial susceptibility of H. pylori strains were obtained from 39 patients. Resistance to metronidazole was detected in 20 patients (51%), to clarithromycin in 3 patients (8%), to levofloxacin in 9 patients (23%) and to bismuth in 2 patients (5%). There was no observed resistance to amoxicillin, tetracycline or furazolidone. CONCLUSION Due to the low amoxicillin and clarithromycin resistance observed in this study, therapies using these antimicrobials remain appropriated first-line H. pylori therapy.

Abstract
CONTEXT Gastroesophageal reflux disease is one of the most common digestive diseases and an important cause of distress to patients. Diagnosis of this condition can require ambulatory pH monitoring. OBJECTIVES To determine the diagnostic yield of a wireless ambulatory pH monitoring system of 48-hours, recording to diagnose daily variability of abnormal esophageal acid exposure and its symptom association. METHODS A total of 100 consecutive patients with persistent reflux symptoms underwent wireless pH capsule placement from 2004 to 2009. The wireless pH capsule was deployed 5 cm proximal to the squamocolumnar junction after lower esophageal sphincter was manometrically determined. The pH recordings over 48-h were obtained after uploading data to a computer from the receiver that recorded pH signals from the wireless pH capsule. The following parameters were analyzed: (1) percentual time of distal esophageal acid exposure; (2) symptom association probability related to acid reflux. The results between the first and the second day were compared, and the diagnostic yield reached when the second day monitoring was included. RESULTS Successful pH data over 48-h was obtained in 95% of patients. Nearly one quarter of patients experienced symptoms ranging from a foreign body sensation to chest pain. Forty-eight hours pH data analysis was statistically significant when compared to isolated analysis of day 1 and day 2. Study on day 2 identified seven patients (30.4%) that would be missed if only day 1 was analyzed. Three patients (18.7%) out of 16 patients with normal esophageal acid exposure on both days, showed positive symptom association probability, which generated an increase in diagnostic yield of 43.4%. CONCLUSION Esophageal pH monitoring with wireless capsule is safe, well tolerated, does not require sedation. The extended 48-h period of study poses an increased yield to diagnose gastroesophageal reflux disease patients.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most common disorders in medical practice. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Brazilian accepted directive by the standards of evidence-based medicine is still lacking. As such, the aim of the Brazilian GERD Consensus Group was to develop guidelines for the diagnosis and management of GERD, strictly using evidence-based medicine methodology that could be clinically used by primary care physicians and specialists and would encompass the needs of physicians, investigators, insurance and regulatory bodies. A total of 30 questions were proposed. Systematic literature reviews, which defined inclusion and/or exclusion criteria, were conducted to identify and grade the available evidence to support each statement. A total of 11,069 papers on GERD were selected, of which 6,474 addressed the diagnosis and 4,595, therapeutics. Regarding diagnosis, 51 met the requirements for the analysis of evidence-based medicine: 19 of them were classified as grade A and 32 as grade B. As for therapeutics, 158 met the evidence-based medicine criteria; 89 were classified as grade A and 69 as grade B. In the topic Diagnosis, answers supported by publications grade A and B were accepted. In the topic Treatment only publications grade A were accepted: answers supported by publications grade B were submitted to the voting by the Consensus Group. The present publication presents the most representative studies that responded to the proposed questions, followed by pertinent comments. Follow examples. In patients with atypical manifestations, the conventional esophageal pH-metry contributes little to the diagnosis of GERD. The sensitivity, however, increases with the use of double-channel pH-metry. In patients with atypical manifestations, the impedance-pH-metry substantially contributes to the diagnosis of GERD. The examination, however, is costly and scarcely available in our country. The evaluation of the histological signs of esophagitis increases the diagnostic probability of GERD; hence, the observation of the dimensions of the intercellular space of the esophageal mucosa increases the probability of diagnostic certainty and also allows the analysis of the therapeutic response. There is no difference in the clinical response to the treatment with PPI in two separate daily doses when compared to a single daily dose. In the long term (>1 year), the eradication of H. pylori in patients with GERD does not decrease the presence of symptoms or the high recurrence rates of the disease, although it decreases the histological signs of gastric inflammation. It seems very likely that there is no association between the eradication of the H. pylori and the manifestations of GERD. The presence of a hiatal hernia requires larger doses of proton-pump inhibitor for the clinical treatment. The presence of permanent migration from the esophagogastric junction and the hernia dimensions (>2 cm) are factors of worse prognosis in GERD. In this case, hiatal hernias associated to GERD, especially the fixed ones and larger than 2 cm, must be considered for surgical treatment. The outcomes of the laparoscopic fundoplication are adequate.

Abstract
CONTEXT Non-cardiac chest pain or functional chest pain is a syndrome with high prevalence in occidental world. Findings on 15%-30% of coronary angiograms performed in patients with chest pain are normal. Causes significant impact in quality of life of patients and is associated with increased use of the health care facilities. DATA SOURCES To this review the following data base were accessed: Medline, the Cochrane Library, LILACS. The limit was the last 5 years publications and were selected relevant original articles, reviews, consensus, guidelines and meta-analysis. RESULTS Forty-four papers were selected, 28 original articles, 12 reviews, 2 guidelines, 1 consensus and 1 meta-analysis. CONCLUSIONS Exclusion of cardiac disease is of crucial importance. On the other hand non-cardiac chest pain could be related to gastrointestinal, muscular and respiratory causes and/or psychological disturbances. Treatment aims to attack mechanism generator in order to relieve or to eliminate symptoms. Drugs are the cornerstone of treatment, exception to achalasia patients because those have better response to dilation of the esophagus or surgery, and to those who need intensive psychological therapy. The most important drugs used are proton pump inhibitors and tricyclic antidepressants, the latter, to modulate central signal process (visceral hypersensitivity) and autonomic response. Recently, new diagnostic facilities, and also therapeutic modalities, such as esophageal botulin toxin injection and hypnosis are under investigations. In the near future, maybe some of them would take a place in the therapeutic scenario of these patients.

Abstract
INTRODUCTION Several aspects of gastroesophageal reflux disease (GERD) have been studied, but the frequency of comorbidities is not yet fully understood. OBJECTIVES To study the prevalence of GERD comorbidities in a tertiary care hospital. METHODS We prospectively studied 670 consecutive adult patients from the outpatient department of our facility. A diagnosis was established using clinical, endoscopic and/or pHmetry-related findings. Each patient's medical file was reviewed with respect to the presence of other medical conditions and diagnoses. RESULTS Of the 670 patients, 459 (68.6%) were female, and the mean age was 55.94 (17-80 years). We registered 316 patients (47.1%) with the erosive form of GERD and 354 patients (52.9%) with the non-erosive form. A total of 1,664 instances of comorbidities were recorded in 586 patients (87.5%), with the most common being arterial hypertension (21%), hypercholesterolemia (9%), obesity (9%), type II diabetes mellitus (5%) and depression (4%). Two or more comorbidities were present in 437 individuals (64.8%). The occurrence of comorbidities increased with age and was higher in patients with the non-erosive form of GERD. CONCLUSIONS In a tertiary referral population, comorbidities were very common, and these may have worsened the already impaired health-related quality of life of these patients. Clinicians caring for GERD patients in this setting must be aware of the likelihood and nature of comorbid disorders and their impact on disease presentation and patient management.

Abstract
Patients with primary head and neck cancers have a higher risk of developing esophageal cancer. The aim of this study was to investigate esophageal cancer prevalence, its risk factors (ethanol and tobacco consumption) and dietary habits in patients with head and neck cancer. Three hundred and twenty-six adults with primary head and neck cancer were followed by a retrospective observational study in a general university hospital in Sao Paulo, Brazil. Flexible videoendoscopy with lugol chromoscopy was the method used to investigate esophageal cancer prevalence. All subjects were interviewed face-to-face, revealing detailed information about their tobacco and alcohol use, as well as their dietary habits. Thirty-six patients with esophageal cancer were diagnosed and the overall prevalence rate was 11.04%. Patients who developed second esophageal tumors had the following characteristics: earlier age of initial ethanol consumption (P < 0.05), longer duration period of ethanol consumption (P < 0.05) and higher weekly consumption rate (P < 0.05). There was an increased risk of esophageal carcinoma in those patients who both smoked and drank (P < 0.05). There was no association between carcinoma of the esophagus and dietary habits in patients who developed esophageal neoplasms, compared with those who did not. Prevalence rate of esophageal neoplasms was 11.04% in patients with head and neck carcinoma, whose ethanol consumption was associated with esophageal cancer. There was an increased risk between ethanol and tobacco consumption and esophageal carcinoma development. On the other hand, there was no association regarding dietary habits between patients who developed esophageal cancer and those who did not.

Abstract
BACKGROUND The epidemiological aspects of heartburn and gastroesophageal reflux disease have been object of growing interest in the last decade because of its increasing prevalence and the complications of the disease. AIMS To evaluate the prevalence of heartburn and gastroesophageal reflux disease as well as their main characteristics in the Brazilian urban population. METHODS A national inquire enrolling 13,959 adults was conducted in 22 Brazilian cities. The inclusion criteria were the presence of heartburn at least once a week ("heartburn group") and age greater than 16 years old. Individuals with heartburn with frequency of more than once a week were considered as having gastroesophageal reflux disease (GERD group). Factors related to the complaint were asked such as predisposing factors, habits (tobacco, alcohol and coffee intake) and body mass index. In this populational study a probabilistic model was used. RESULTS The results are presented in absolute and relative frequency, which were ponderated estimates of the respective population figures. The global prevalence of heartburn was 11.9% (1,651 persons). Heartburn once a week was present in 4.6% (637 persons) and GERD in 7.3% (1,014 persons). The average ages of both groups were similar (men: 36.9 +/- 15.0; women: 39.6 +/- 15.1 yrs). Females were more affected in both groups. The occurrence of GERD increased with age and was more prevalent after 55 years old. The body mass index was in the normal range and similar in both groups (men: 24.7 +/- 4.6; women: 25.3 +/- 5.2 kg/m(2)). In both groups the individuals related their symptoms to food intake, fatty and spicy foods (heartburn group: 64.7%, 28.5%, 17.7%; GERD group: 55.0%, 25.9%, 11.7% respectively). In GERD group, stress (24.2%), health problems (22.3%) were more related to the symptoms than in heartburn group (20.0% and 15.0% respectively). CONCLUSIONS The global prevalence of heartburn (11.9%) is relatively high in the Brazilian urban population, although lower than the reported figure to other countries. Heartburn and GERD have higher prevalence in women and both are related to food intake, fatty and spicy foods; GERD is more prevalent in individuals older than 35 years old.

Abstract
OBJECTIVE Patients with primary head and neck cancer show a predisposition to develop esophageal cancer. The aim of this study was to investigate in these patients: the prevalence of esophageal cancer comparing the value of chromoendoscopy using Lugol's solution examination to standard endoscopy, in the early diagnosis of esophageal cancer. METHODS Prospective observational study at a state general university hospital in Sao Paulo, Brazil. 326 consecutive adult patients with primary head and neck cancer were evaluated. A standard endoscopy was performed, followed by a 2% Lugol's dye spray chromoendoscopy and histopathologic study. The prevalence of esophageal cancer was defined. The results of the two endoscopic methods were compared. RESULTS Twenty-four patients with esophageal cancer and high-grade intraepithelial neoplasia were detected and had a prevalence of 7.36%. Chromoendoscopy and standard endoscopy were equivalent to the diagnosis of advanced and invasive esophageal cancer. However, standard endoscopy diagnosed 55% of high-grade intraepithelial neoplasia, in comparison to chromoendoscopy that detected 100%. CONCLUSIONS Patients with primary head and neck cancer should be considered as high risks for the presence of esophageal cancer. Lugol's dye chromoendoscopy diagnosed high-grade intraepithelial neoplasia, which went unnoticed with standard endoscopy. It permits a more exact detection of lesion boundaries and facilitates a more precise targeting of biopsy fragments.

Abstract
The effect of the reduction of intra-abdominal pressure on the lower esophageal sphincter pressure (LESP) and the 24-hour pH monitoring were studied in 16 patients with ascites before and after paracentesis. LESP did not change (P > 0.05) with the reduction of intra-abdominal pressure (before paracentesis: 17.48 mmHg and postparacentesis: 18.67 mmHg). The results were divided into two groups according to the achieved reduction in intra-abdominal pressure group A were those in who the reduction was greater than 70% and B consisted of those a reduction of less than 70%. LESP did not change even when results for each group were considered separately (P > 0.05): group A (before: 15.60 mmHg; after: 18.09 mmHg); group B (before: 23.09 mmHg; after: 20.40 mmHg). However the 24-h pH monitoring showed pathological reflux in patients with ascites that was reduced with the paracentesis (P < 0.05; total number of reflux episodes before paracentesis was 520.26, and after, 136.26). All pH-monitoring parameters were statistically different (P < 0.05) before and after the reduction of intra-abdominal pressure for group A but not for group B. LESP does not change significantly (P > 0.05) when the intra-abdominal pressure is significantly reduced (P < 0.05). Patients with ascites showed gastroesophageal reflux. Intra-abdominal pressure reduction greater than 70% lead to a significant reduction in gastroesophageal reflux.

Abstract
According to the WHO, 16-18 million people in Central and South America are infected by Trypanosoma cruzi. Chagasic achalasia affects between 7.1% and 10.6% of the population. The aim of this study was to evaluate the effects of Botox injections in the clinical response and esophageal function of patients with dysphagia due to chagasic achalasia. In total, 24 symptomatic patients with chagasic achalasia were randomly chosen to receive Botulinum Toxin (BT) or saline injected by endoscopy in the lower esophageal sphincter (LES). Patients were monitored with a clinical score of dysphagia and an objective assessment (esophagograms, scintillography, manometry, and nutritional assessment) for a period of 6 months. Clinical improvement of dysphagia was statistically significant (P < 0.001) in patients receiving BT when compared with the placebo. There was no significant difference in the placebo group regarding clinical score, LES basal pressure and esophageal emptying time. Esophageal emptying time in the toxin group was significantly lower than in the placebo (P=0.04) after 90 days. There were non-significant increases in esophageal emptying of 25.36% and 17.39%, respectively, at 90 and 180 days, in the BT group (P=0.266). Gender, age, and baseline LES pressure did not influence the response to BT. Our data strongly suggests that intrasphincteric injection of BT in LES is clinically effective in the treatment of chagasic achalasia.

Abstract
Patients with reflux esophagitis (grade II or III, Savary-Miller, intention-to-treat, n=256, age range 19-82 years) were randomly assigned to a double-blind, double-dummy treatment with either pantoprazole 40 mg once daily or ranitidine 150 mg twice daily. After 4 weeks, each patient was clinically and endoscopically assessed. Failure to heal required a further 4 weeks of treatment and a new evaluation thereafter. After 4 weeks, healing of lesions was confirmed in 63% (69 out of 109) of patients receiving pantoprazole and in 22% (25 out of 113) receiving ranitidine (P < 0.001, per protocol population). After 8 weeks, the cumulative healing rates were 88% and 46%, respectively (P < 0.001). Complete freedom from esophagitis-related symptoms (acid eructation, heartburn, pain while swallowing) was greater in the pantoprazole than in ranitidine group after 2 and 4 weeks (74% vs. 47%; 87% vs. 52%, respectively, P < 0.001). After 4 weeks, the healing rate was 76% in Helicobacter pylori (Hp)-positive vs. 45% in Hp-negative patients treated with pantoprazole (P < 0.01). The Hp status did not influence healing rates in patients treated with ranitidine. The most frequent adverse events in the pantoprazole group were diarrhea and somnolence (2-3% of patients), and in the ranitidine group, headache, diarrhea, dizziness, increase of liver enzymes and pruritus (2-4% of patients). In conclusion, pantoprazole was more effective than ranitidine in the healing rate and relief from reflux esophagitis-associated symptoms, and Hp infection was associated with higher healing rate during therapy with pantoprazole but not with ranitidine.
