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
BACKGROUND Psoriasis is an inflammatory skin disease that affects 1%-3% of Caucasian populations and may be persistent, disfiguring and stigmatising. Proton pump inhibitors (PPI) are potent blockers of gastric acid secretion. They are widely regarded as the agents of choice for the treatment of acid-peptic disorders. In addition to anti-secretory effects PPI have been found to have anti-oxidant properties and direct effects on neutrophils, monocytes, endothelial, and epithelial cells that might prevent inflammation. OBJECTIVE This study evaluated the treatment of psoriasis with esomeprazole. METHODS Ten patients were selected and psoriasis was evaluated according to Psoriasis Area and Severity Index (PASI). Exclusion criteria included concomitant use of any treatment for Psoriasis, organic diseases, use of other PPI than esomeprazole. Patients were medicated with esomeprazole 40 mg B.I.D. for 90 days. At the 90th day the patients were evaluated according PASI score. RESULTS Statistically significant results were seen when compared PASI before and at 90th day of treatment (P=0.0002). CONCLUSION The use of esomeprazole for psoriasis resulted in excellent clinical results with a significant reduction of PASI score.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal diseases. GERD generates significant impairment in patients' quality of life and it is associated to relevant medical resources utilization. A better understanding of GERD pathophysiology in the past five decades has favored the evolution of therapeutic strategies from non-drug interventions and antacids to more efficacious and safer alternatives. OBJECTIVE To summarize data about the historical evolution of GERD management in Brazil, focusing on medical therapy and addressing evidence on efficacy and safety of drug classes currently recommended. METHODS A narrative review was conducted by systematizing information about discoveries on GERD pathophysiology. We also addressed efficacy and safety of medications currently used to reduce symptoms and improve endoscopic healing of esophageal lesions. A structured search on Pubmed was performed to identify systematic reviews and meta-analysis investigating GERD outcomes positively impacted by proton pump inhibitors (PPIs), the first choice of pharmacotherapy for the disease. RESULTS The chronological development of therapeutic measures for GERD in Brazil evolved from lifestyle interventions with relative poor effect on symptoms related to esophageal acid exposure, particularly heartburn, to effective and safe pharmacological interventions such as histamine H2-receptor antagonists and PPIs. In the present days, some drug classes play a minor role in disease management, namely prokinetics and antacids, due to their reduced efficacy and relevant safety concerns (particularly with prokinetics). The main challenge for prescribers and researchers seems to be finding long-acting acid suppressants strategies able to ameliorate patients' symptoms and quality of life, thereafter, reducing medical resource consumption. The dual delayed-release PPI dexlansoprazole seems to respond for some of the limitations other PPIs have. CONCLUSION Recognizing the historical evolution of GERD management can help care providers to better understand therapeutic options for their patients, as well as focus on unmet needs that deserve further attention. PPIs are still the first choice therapy, with good evidence in favor of their efficacy, despite some safety concerns. However, as with any medical intervention, it is recommended to prescribe PPIs for patients with clear indication, using adequate dosing and monitoring for adverse events.

Abstract
Introduction: The scheme proton pump inhibitor/amoxicillin/clarithromycin (PPI/AC) is still the first-line treatment for Helicobacter pylori (H. pylori) infections despite evidence suggesting its failure in up to 20% to 30% of patients. Methodology: This study involved 493 patients who were prescribed omeprazole (20 mg twice a day) or another proton pump inhibitor in equivalent dosage, amoxicillin (1 g twice a day), and clarithromycin (500 mg twice a day) for seven days. Efficacy was determined by negative urease test and absence of H. pylori on gastric biopsy samples twelve weeks after the end of treatment. Safety was defined according to the adverse effects reported. Mean age of the patients was (± SD) 48.96 ± 13, and demographic and clinical data were recorded for correlation with treatment outcomes. Results: Out of 493 patients, 316 (64.1%) presented duodenal ulcer, 111 (22.5%) gastric ulcer, and 66 (14.4%) simultaneous gastric and duodenal ulcers. Additionally, 267 (54.2%) patients had at least one risk factor for peptic ulcer disease, smoking being the most common (99 [36.5%]). Successful eradication was achieved in 408 patients. The eradication rates per protocol, and according to the intention to treat, were 88.8% and 82.7%, respectively. Of 164 (35.5%) patients who presented adverse effects, 100 (61%) reported them as mild and only six (3.7%) patients had to discontinue treatment. Previous use of tobacco and non-steroid anti-inflammatory drugs was the only risk factor for treatment failure (P 0.00). Conclusion: PPI/AC is still a valuable and remarkably tolerable option for first-line H. pylori eradication in Brazil.

Abstract
Background Increasing resistance to clarithromycin and nitroimidazole is the main cause of failure in the Helicobacter pylori eradication. The ideal retreatment regimen remains unclear, especially in developing countries, where the infection presents high prevalence and resistance to antibiotics. The study aimed at determining the efficacy, compliance and adverse effects of a regimen that included furazolidone, levofloxacin and lansoprazole in patients with persistent Helicobacter pylori infection, who had failed to respond to at least one prior eradication treatment regimen. Methods This study included 48 patients with peptic ulcer disease. Helicobacter pylori infection was confirmed by a rapid urease test and histological examination of samples obtained from the antrum and corpus during endoscopy. The eradication therapy consisted of a 7-day twice daily oral administration of lansoprazole 30 mg, furazolidone 200 mg and levofloxacin 250 mg. Therapeutic success was confirmed by a negative rapid urease test, histological examination and 14C- urea breath test, performed 12 weeks after treatment completion. The Chi-square method was used for comparisons among eradication rates, previous treatments and previous furazolidone use. Results Only one of the 48 patients failed to take all medications, which was due to adverse effects (vomiting). Per-protocol and intention-to-treat eradication rates were 89% (95% CI- 89%–99%) and 88% (88–92%), respectively. Mild and moderate adverse effects were reported by 41 patients (85%). For patients with one previous treatment failure, the eradication rate was 100%. Compared to furazolidone-naïve patients, eradication rates were lower in those who had failed prior furazolidone-containing regimen(s) (74% vs. 100%, p = 0.002). Conclusion An empiric salvage-regimen including levofloxacin, furazolidone and lansoprazole is very effective in the eradication of Helicobacter pylori, particularly in patients that have failed one prior eradication therapy.

Abstract
AIM: To establish the efficacy and safety of a 7-d therapeutic regimen using omeprazole, bismuth subcitrate, furazolidone and amoxicillin in patients with peptic ulcer disease who had been previously treated with other therapeutic regimens without success.
METHODS: Open cohort study which included patients with peptic ulcer who had previously been treated unsuccessfully with one or more eradication regimens. The therapeutic regimen consisted of 20 mg omeprazole, 240 mg colloidal bismuth subcitrate, 1000 mg amoxicillin, and 200 mg furazolidone, taken twice a day for 7 d. Patients were considered as eradicated when samples taken from the gastric antrum and corpus 12 wk after the end of treatment were negative for Helicobacter pylori (H pylori) (rapid urease test and histology). Safety was determined by the presence of adverse effects.
RESULTS: Fifty-one patients were enrolled. The eradication rate was 68.8% (31/45). Adverse effects were reported by 31.4% of the patients, and these were usually considered to be slight or moderate in the majority of the cases. Three patients had to withdraw from the treatment due to the presence of severe adverse effects.
CONCLUSION: The association of bismuth, furazolidone, amoxicillin and a proton-pump inhibitor is a valuable alternative for patients who failed to respond to other eradication regimens. It is an effective, cheap and safe option for salvage therapy of positive patients.

Abstract
BACKGROUND The prevalence of Helicobacter pylori is higher in developing countries. Sanitary facilities, crowding and ethnic group are some of the factors related to H. pylori infection. The aim of this study was to investigate in blood donors, free of dyspeptic symptoms, the prevalence and factors influencing H. pylori infection. MATERIALS AND METHODS This study was conducted in São Paulo, a city known to have a mixed population coming from all over the country. A total of 1008 blood donors were initially included in the study. After a final revision of all the questionnaires, 993 were included in the final analysis (746 males). H. pylori status was checked by an ELISA test. The following associations to infection were analyzed: sex, age, ethnic group, previous upper gastrointestinal (GI) endoscopy, smoking, alcoholism, drug addiction, type of drinking water, crowding, sanitary facilities, and family income. RESULTS Infection was observed in 496 of 746 male (66.5%) and in 156 of 247 female (63.2%) blood donors. Infection prevalence increased according to age group, regardless of sex. Prevalence was lower in White population than in non-White. No relationship was observed between infection and smoking, drug addiction, and alcohol. A positive relation was observed between infection and previous upper GI endoscopy, and type of drinking water, regardless if currently or during childhood. Crowding and lack of toilet in the house during childhood resulted in a higher infection rate. Lower familial income and educational level showed a positive association to infection. CONCLUSIONS Prevalence of H. pylori is higher in non-White population, independent of gender. A positive association was observed in aging, previous upper GI endoscopy, crowding, type of drinking water, lack of toilet during childhood, lower family income, and lower educational level.

Abstract
BACKGROUND Recurrence infection following successful eradication of Helicobacter pylori is usually low, except for countries with high prevalence of H. pylori. The aim of this study was to verify H. pylori recurrence rate in patients with duodenal ulcer after eradication and the possible relationship with environmental factors, histologic pattern of the mucosa and bacterial genotype. MATERIALS AND METHODS One-hundred and ninety-four patients with an active duodenal ulcer and who were successfully treated for H. pylori infection from 1990 to 1999 were studied. A questionnaire was answered about their living conditions, and a 14C-urea breath test was performed. Patients with a positive breath test underwent an upper endoscopy to investigate for possible ulcer recurrence; gastric biopsy samples were than collected for rapid urease test and for histologic assessment. H. pylori vacA and cagA genotype was determined by polymerase chain reaction in those samples with positive urease test. RESULTS H. pylori infection was detected in 11 patients (recurrence rate of 5.7%) that were not associated with the type of bacterial virulence. In 10 patients the ulcer was healed and all of them were clinically asymptomatic. In eight, histology showed an intensification of gastritis. All 11 patients had adequate housing and sanitary conditions and no other risk for H. pylori recurrence was identified. CONCLUSIONS The recurrence rate of H. pylori in Brazil was higher than that reported in developed countries, but lower than usually reported in developing ones. Ulcer relapse rarely occurs even in long-term follow up.

Abstract
This survey was designed to evaluate the prevalence of Helicobacter pylori infection in asymptomatic children from families of low and high socioeconomic status living in two neighboring communities in Teresina in northeastern Brazil. The study included 303 children, 163 (53.8%) males and 140 (46.2%) females, ranging in age from 6 months to 12 years. Helicobacter pylori status was determined by the H. pylori stool antigens test, in which sensitivity and specificity values for Brazilian children were 96.9% and 100%, respectively. The prevalence rates were 55.0% (93 of 169) and 16.4% (22 of 134) for children of low and high socioeconomic status, respectively (P < 0.001). Infection with H. pylori occurred early in life (before 2 years of age) in both groups (22.9% versus 14.3%; P = 0.061) and increased as the children became older. The rate of infection in children 11-12 years of age living in the poor area was as high as the levels found in Brazilian adults. An improved standard of living is followed by a sharp decrease in the prevalence rates in children, even in a developing country such as Brazil.

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
BACKGROUND Esomeprazole, an S-isomer of omeprazole, is the first proton pump inhibitor developed as an optical isomer, and it has shown high healing rates in erosive esophagitis. AIM To evaluate the efficacy and tolerability of esomeprazole in subjects with erosive esophagitis, according to the Los Angeles classification study design: an open, multi-center clinical study. MATERIAL AND METHODS Two hundred and eighteen subjects with reflux esophagitis confirmed by endoscopy were included in an open, multi-center study in Brazil. All of them received esomeprazole 40 mg, once daily, for a 4-week period. Subjects who had unhealed esophagitis by week 4 continued the treatment for another 4 weeks. The primary efficacy endpoint was the healing rates by weeks 4 and 8. The secondary endpoints were the number of patients with symptom resolution by week 4, the number of days to sustained symptom resolution, number of symptom-free days and nights and safety and tolerability of the drug. RESULTS Healing rates by weeks 4 and 8 were 82% (confidence interval: 77.4%-87.6%) and 96.1% (confidence interval: 93.5% - 98.8%), respectively. Ninety-nine (99%) of the patients had heartburn resolution by week 2. The most common adverse events were headache (4%), diarrhea (2.6%) and epigastric pain (2.2%). CONCLUSION For the studied period, esomeprazole was shown to be a safe and well-tolerated drug, providing significant healing rates of mucosal breaks, regardless of LA classification, in patients with erosive esophagitis. Esomeprazole was also shown to be effective in quickly relieving symptoms.

Abstract
UNLABELLED Triple therapy is accepted as the treatment of choice for H. pylori eradication. In industrialized countries, a proton pump inhibitor plus clarithromycin and amoxicillin or nitroimidazole have shown the best results. Our aims were: 1. To study the eradication rate of the association of a proton pump inhibitor plus tinidazole and clarithromycin on H. pylori infection in our population. 2. To determine if previous treatments, gender, age, tobacco, alcohol use, and non-steroidal anti-inflammatory drugs (NSAIDs) change the response to therapy. METHODS Two hundred patients with peptic ulcer (upper endoscopy) and H. pylori infection (histology and rapid urease test - RUT) were included. A proton pump inhibitor (lanzoprazole 30 mg or omeprazole 20 mg), tinidazole 500 mg, and clarithromycin 250 mg were dispensed twice a day for a seven-day period. Eradication was assessed after 10 to 12 weeks of treatment through histology and RUT. RESULTS The eradication rate of H. pylori per protocol was 65% (128/196 patients). This rate was 53% for previously treated patients, rising to 76% for not previously treated patients, with a statistical difference p<0.01. No significant difference was observed regarding sex, tobacco use, alcohol consumption, and NSAID use, but for elderly patients the difference was p = 0.05. Adherence to treatment was good, and side effects were mild. CONCLUSIONS A proton pump inhibitor, tinidazole, and clarithromycin bid for seven days resulted in H. pylori eradication in 65% of the patients. Previous treatments were the main cause of treatment failure.

Abstract
OBJECTIVE The aim of this study was to compare the effectiveness and tolerance of pantoprazole versus ranitidine in the treatment of duodenal ulcers in the Brazilian population. METHODS A total of 222 patients with active duodenal ulcers (DU) were randomly allocated to a double dummy blind treatment, either with ranitidine (RAN) 300 mg (111, aged from 20-68 yr old, 56 female) or with pantoprazole (PANT) 40 mg (111 patients, 18-70 yr old, 45 female). After a 2-wk course of treatment, each patient was clinically and endoscopically assessed for ulcer healing. Failure to heal required a further 2-wk course of treatment and a new evaluation thereafter. RESULTS In all, 77 of the 103 patients in the PANT group (74.8%) and 42 of the 94 patients in the RAN group (44.7%) who completed the study had ulcer healing after one 2-wk treatment course, and an additional 23 in the PANT group (22.3%) and 28 in the RAN group (29.8%) after the second 2-wk treatment course, totaling 100 (97.1%) and 70 (74.5%), respectively. Therapeutic gain in favor of pantoprazole was significant both at the end of the first and the second 2-wk treatment course (p<0.001). At 2 wk, symptoms remission was significantly higher in the PANT group (97.6%) than with the RAN group (77.5%) (p<0.001). The Intention-to-treat analysis showed results statistically similar to those observed in the per-protocol analysis. Minor adverse events were reported by four patients in the PANT group and three in the RAN group. No relevant laboratory abnormalities were seen. No patient withdrew from the study due to adverse events. CONCLUSIONS Our results show that pantoprazole is more effective than ranitidine in the treatment of duodenal ulcer providing faster ulcer healing in most patients (97.1%), in 4 wk. Adverse events were rare and were similar in both groups, and had no influence on the therapeutic outcome.

Abstract
The incidence of digestive symptoms in 100 patients with Hansen's disease was evaluated in this study, following a standardized questionnaire. A correlation between the frequency of symptoms, the form of the disease, and the length of treatment was investigated. Digestive symptoms were found in 31 patients (31%). No statistically significant difference was found between the presence of symptoms and the length of the disease or between the multibacillary and the paucibacillary form of the disease. However, a positive correlation between digestive symptoms and Hansen's disease was found in the multibacillary form of the disease only for patients treated for more than 12 months. Baseline and pentagastrin-stimulated gastric acid secretion was studied in 30 Hansen's disease patients and in 10 controls. A Iower basal acid output was observed in patients with Hansen's disease, but no statistical difference was found. Pentagastrin-stimulated gastric acid secretion was statistically different in Hansen's disease patients, as compared to controls. A Iower pentagastrin-stimulated acid secretion was found in Hansen's disease patients under treatment, as compared to untreated patients, but the difference was not statistically significant.

Abstract
The sensitivity of endoscopic examinations, acid perfusion test and 24-hour esophageal pH-monitoring, were studied in patients with heartburn. Thirty six adult patients with histological esophagitis were included in this prospective study. Endoscopy showed esophageal lesion in 18/36 (sensitivity of 50%): esophagitis grade I in 10 (55.6%) and, grade II in eight (44.4%). Acid perfusion test was positive in 10/25 (sensitivity of 40%) of the patients submitted to the test. Twenty-four-hour pH-monitoring was positive in 17/29 patients (sensitivity of 58.6%): eight (61.5%) did not have esophageal lesion at endoscopy, two (25%) had esophagitis grade I and seven (87.5%) had esophagitis grade II. In the patients submitted to 24-hour pH-monitoring, a greater number or reflux episodes in orthostatic position than in supine position (P < 0.0001) was observed. The total number of reflux episodes, the most prolonged reflux and the total pH time < 4 were statistically higher in post-prandial period than during meals (P = 0.005).

Abstract
Seventy-seven patients with symptomatic osteoarthritis of the hip and/or knee, with clinical indication for nonsteroidal anti-inflammatory drugs were studied. However, no patient was submitted to any anti-inflammatory medication seven days, prior the beginning of the study and did not complain of any gastrointestinal disease. Shortly before starting the anti-inflammatory drug therapy all patients were submitted to gastroduodenal endoscopy. This diagnostic procedure revealed that 54.6% of the patients presented at least one gastroduodenal damage, 22.1%, hyperemia, 3.9%, petechias, 23.4%, erosions and 5.2%, peptic ulcers. There results permitted to conclude that to identify and/or exclude damage of the gastrointestinal tract, data obtained in the anamnese are not sufficient. For these patients the endoscopic examination is a need. Anti-inflammatory therapy must be careful associated with dietetic orientation and the prescription of drugs to protect the gastrointestinal mucosa.

Abstract
This investigation aimed to compare bacterial eradication and healing in patients with active duodenal ulcer treated with a combination of furazolidone 600 mg/day and metronidazole 750 mg/day and amoxicillin 1.5 and g/day for 5 (TT5) or 10 (TT10) days. Fifty four (TT5 = 28 and TT10 = 26) patients were included in the study. Ulcer healing was observed in 77.8% of TT5 Group and in 75% of TT10 Group at week 4. H pylori eradication was observed in 51.9% and 65% respectively (p > 0.05). When all patients were grouped, a significantly healing rate was observed in those eradicated as compared to those not eradicated (p = 0.03). We concluded that extending the treatment to 10 days did not significantly influence the results of ulcer healing and eradication of Helicobacter pylori.

Abstract
OBJECTIVES To determine the distribution of Helicobacter pylori in the antral and duodenal mucosa of patients with duodenal ulcers refractory to 12 wk of treatment with cimetidine and to evaluate the effect of adding antimicrobial agents to cimetidine on the healing of refractory duodenal ulcers. METHODS A randomized crossover comparison of continued 800 mg of cimetidine at night for 4 wk with cimetidine plus 500 mg of amoxycillin three times a day for the first 2 wk and 250 mg of metronidazole three times a day for the second 2 wk. H. pylori status in the gastric antral and duodenal mucosa was evaluated by histology and bacterial culture before and at the end of each treatment period. RESULTS Forty-eight patients were studied. Upon entry to the study, all patients had antral colonization with H. pylori. In the duodenum, active chronic duodenitis was present in 66%, duodenal gastric metaplasia in 33%, and H. pylori in 50%, similar proportions to patients with nonrefractory duodenal ulcers. Healing occurred in 70% (30 of 43) of patients during treatment with cimetidine plus antimicrobials but in only 21% (6 of 28) during treatment with cimetidine alone (p = 0.0003). In patients who received antimicrobials, neither clearance of H. pylori from the antrum (58% of patients) or duodenum (71% of colonized patients) nor eradication of H. pylori (33%) was significantly correlated with ulcer healing. CONCLUSIONS The distribution of H. pylori in refractory duodenal ulcers is similar to nonrefractory ulcers, and the combination of amoxycillin and metronidazole with cimetidine increases the proportion of refractory duodenal ulcers, which heals.

Abstract
Two hundred and forty-one patients with at least one ulcer at stage A1 or A2, measuring at least 5 mm in its larger diameter, were included in this Brazilian double-blind randomized study. Patients received omeprazole 20 mg in the morning (n = 120) or ranitidine 300 mg at night (n = 121) for 2 wk; unhealed ulcers were treated for an additional 2 wk. At the end of 4 wk, unhealed ulcers were treated openly with omeprazole 20 mg o.m. for 4 wk. Healing rates at 2 and 4 wk were 67.3% and 92.9% for omeprazole and 39.8% and 82.0% for ranitidine (per protocol analysis). Results were similar when analyzed as intention to treat (p significant in favor of omeprazole). Epigastric day-time pain was the most common of all symptoms (89.2%), but only heartburn at day 15 showed a significantly better response to omeprazole than to ranitidine. A multivariate analysis (logit analysis) showed that the odds in favor of healing were greater for small ulcers, nonsmokers, and omeprazole treatment.

Abstract
Antacid (AA) in a very low dose (88 mmol/day) was compared to the standard 800-mg dose of cimetidine in healing duodenal ulcers. The influence of sex, age, symptom duration at entry, night pain, smoking, coffee consumption, and alcohol on ulcer healing was studied. The antacid was given in two different schedules: group I--20 ml 1 hr after breakfast and at bedtime; group II--10 ml 1 hr after breakfast and lunch and 20 ml at bedtime. Cimetidine (group III) was given in two divided doses: 400 mg 1 hr after breakfast and 400 mg at bedtime. Endoscopic control was performed after four weeks and, if necessary, after eight weeks of treatment. The healing rate after four weeks of treatment was, respectively, for groups I, II, and III, 45.5%, 55.8%, and 69.4% (group I = group II, and group III different from groups I and II). After eight weeks of treatment the healing rate was 61.5%, 80.8%, and 88.0% for groups I, II, and III, respectively (group II = group III, and group I different from groups II and III). Except for group I, smoking did not influence healing rate. Age, sex, symptoms at entry, night pain, and coffee consumption did not influence the treatment results. The authors concluded that the very low dose of magaldrate (88 mmol/day), when administered in three divided doses (10 ml after breakfast and lunch and 20 ml at bedtime) for eight weeks was as effective as 800 mg of cimetidine (400 mg twice a day) in healing duodenal ulcer.

Abstract
The ingestion of plain coffee was compared in 150 duodenal ulcer patients (DU) and 100 control subjects without digestive complaints (C). The DU and C groups were registered in accordance with their daily consumption of coffee: none, 1-100 ml, 101-300 ml, 301-500 ml, and more than 500 ml. Fifty millilitres of coffee as prepared in Brazil contain around 50 mg of a caffeine, which is 2.8 times more than in an equal volume of coffee in the United States. Patients with DU stopped drinking coffee or reduced the volume significantly after symptoms started. There was a significant change in coffee intake at all volume levels except at 1-100 ml. The main reason for the reduction of coffee ingestion was the relationship observed by the patients between the consumption of coffee and dyspeptic complaints. Our results suggest a close correlation between the ulcer-like symptoms and the amount of coffee ingested by patients with duodenal ulcer.

Abstract
Twenty five patients with endoscopically diagnosed gastric ulcer, were randomly allocated to treatment with ranitidine 300 mg at night or ranitidine 150 mg twice daily. After six weeks, ulcer healing was observed in 7 out of 14 patients (50%) treated with ranitidine 300 mg nocte and in 7 out of 11 (63.6%) receiving 150 mg bid. Cumulative healing rates at 12 weeks were 64.2% and 81.8%, respectively. There was no statistically significant difference between these two groups. No adverse events were reported by any patient. Ranitidine 300 mg administered at night was effective and a safe regimen for the treatment of gastric ulcer.

Abstract
Fifty-five patients with an endoscopically confirmed duodenal ulcer were randomly allocated to receive ranitidine 300 mg either in a single morning or a single nocte dose (26 and 29 patients respectively). They were endoscopically examined at the end of the second week and when the ulcer was still active, the patient was treated for another two weeks, when endoscopy was repeated. Patients with ulcers still active at four weeks were considered treatment failures. The healing rate observed when ranitidine 300 mg was given in the morning was 10/26 (38%) at the end of the second week and 17/26 (65%) at the end of the fourth week. The healing rates after the 300 mg nocte treatment was 12/29 (41%) at the end of the second week and 20/29 (68%) at the end of the fourth week. No side effects were observed in any of the 55 patients, although one patient in the morning regimen bled at the end of the second week and was withdrawn from the study. Our results showed that ranitidine 300 mg in a single morning dose is as effective as when given in a single night dose. This finding is suggestive that reduction of nocturnal gastric acid secretion is important, but not essential for the healing of duodenal ulcer.

Abstract
The clinical evolution and treatment of two patients with alcoholic chronic pancreatitis complicated with digestive hemorrhage localized in the gastric corpus and fundus are discussed. The clinical picture and the endoscopic features suggested that the hemorrhage was due to hemorrhagic gastritis and not to rupture of varicose veins. Hemorrhagic gastritis as a consequence of segmentary portal hypertension may be responsible for the difficulty in establishing the etiology of digestive hemorrhage in such cases.

Abstract
Two hundred and thirty five duodenal ulcer patients agreed to be treated with Misoprostol 400 mcg b.i.d. during four weeks. The influence of cigarette smoking, alcohol and coffee on the healing rate were determined. Endoscopic examinations were performed at the beginning of the study and after four weeks of treatment. Clinical evaluations were done at the beginning and after two and four weeks of treatment. According to the type of cohort the healing rate after four weeks of treatment was: a) 70.6% when all 235 patients intended to be treated were considered; b) 77.9% when all patients reexamined after four weeks + 5 withdrawn because of side effects (3) or worsening of symptoms (2) where analysed and, c) 79.8% when only the 208 patients that completed four weeks of treatment were considered. Loosen stools or diarrhea were observed in 37% of the patients but only in 2 (0.85%) severe diarrhea resulted in interruption of the treatment. The healing rates were not altered by the use of cigarettes, alcohol or coffee, suggesting that Misoprostol probably inhibited the deleterious effects of those risk factors.

Abstract
The relationship between chronic gastritis and peptic ulcer was studied in 97 patients, 51 with duodenal ulcer and 46 with gastric ulcer. Six biopsies (three from the antrum and three from the body) were obtained under direct vision by means of an Olympus panendoscope. Chronic gastritis was classified according to the grade of inflammation (slight or moderate and intense), and to its location (antritis or pangastritis). In gastric ulcer the relationship between frequency of chronic gastritis and the site of the ulcer (antrapyloric, at the angulus, body of the stomach) was also established. Antritis was just as frequently observed in duodenal ulcer (94%) as in gastric patients (96%), but severe inflammation of the antrum was higher in G.U. (43%) than in D.U. (17%). Chronic gastritis of the gastric body was always accompanied by antritis, both in G.U. and in D.U. and was observed in 63% of the former group and 37% of the latter. Severe inflammation of the glandular portion of the stomach occurred in only one patient with D.U (2%) and in 7 with G. U (15%). In the present investigation, no relationship between between the site of gastric ulcer and the frequency of chronic gastritis was observed.

Abstract
In 16 healthy subjects, gastric distention was produced by infusion of 5% mannitol solution, pH 5.5. Constant intragastric pressure was maintained by use of a barostat. Over successive 1-hr periods the head of pressure was raised in 5-cm increments from an arbitrary zero point to 15 cm. Gastric acid secretion was measured by constant intragastric titration. Blood samples were obtained throughout the study for measurement of serum gastrin concentrations. When intragastric pressure was raised from zero to 5 cm H2O, gastric acid secretion increased significantly (24% of peak acid response to pentagastrin). Acid responses at 10 and 15 cm pressure were lower. Serum gastrin concentrations increased slightly at 15 cm pressure but not at 5 or 10 cm. There was no correlation between increments in serum gastrin and acid secretory rates. We conclude that gastric distention at low pressures stimulated acid secretion by a mechanism and did not involve increases in circulating gastrin concentrations. Slight increases in serum gastrin observed at the highest distending pressure were not associated with further increases in acid secretion.
