Abstract
Risk factors of slow healing were previously researched in a large sample of duodenal (DU) and gastric ulcer (GU) patients over 65 years of age; persistence of ulcer symptoms was proven the most reliable factor in predicting nonhealing ulcer, while ulcer size was of importance only for DU. We aimed to complete the analysis, with a more careful evaluation of concomitant diseases and therapies. Ranitidine 300 mg daily was given for four to eight weeks to 310 GU and 699 DU patients. Ninety-three patients dropped out of the study; 79/294 gastric ulcers and 138/635 duodenal ulcers were unhealed after four weeks. Cardiovascular, gastrointestinal, and pulmonary disorders were the most frequent concomitant diseases; NSAIDs, cardiovascular drugs, and antihypertensives were the most frequent concomitant therapies. Esophagitis was diagnosed in 15.5% of patients. Ulcer healing was the major determinant of persistence of ulcer symptoms; esophagitis emerged as an important adjunctive and independent factor. Use of hypoglycemic agents in the whole sample and smoking habit (in GU) may have also a role. With persistence of ulcer symptoms removed from the analysis, ulcer size was the most constant factor affecting ulcer healing. NSAID use, cardiovascular disorders, esophagitis (in GU), and concomitant therapy with cardiovascular drugs (in DU) also play a role. In conclusion, persistence of ulcer symptoms, the major indicator of slow ulcer healing in the elderly, is independently affected also by the presence of esophagitis. Use of hypoglycemic agents and smoking habit may also have a role in persistence of ulcer symptoms. NSAIDs, cardiovascular disorders, cardiovascular drugs, and esophagitis affect ulcer healing, for which the most constant indicators remained persistence of ulcer symptoms and ulcer size.

Abstract
Little is known about ulcer outcome in the elderly. The aims of the present paper were to establish whether risk factors of slow-healing peptic ulcer can be demonstrated in the elderly and whether clinical differences exist between ulcer patients whose age of onset of the disease was before or after 65 years old. The short-term, open study, involving 1052 elderly patients (over 65 years) in 37 gastroenterology centers throughout Italy aimed to compare two schedules of ranitidine treatment: 150 mg twice daily versus 300 mg at bedtime. As nonsignificant differences were found between these two schedules, the sample was considered as a whole. It included 319 gastric ulcer (GU) patients, 699 duodenal ulcer (DU) patients, and 34 concomitant GU and DU cases. Ninety-three patients dropped out of the trial; 79/294 GU, 138/635 DU, and 10/30 GU+DU were found still unhealed after four weeks and 20 GU, 15 DU, and 1 GU+DU remained so after eight weeks. Statistical analysis was performed using likelihood-ratio and Pearson's chi-squared tests and Cox's models. Univariate analysis showed that the indicators of slow-healing GU were ulcer size (P = 0.002) and persisting ulcer symptoms (P = 0.0001); indicators of slow-healing DU were ulcer size (P = 0.0001), persisting ulcer symptoms (P = 0.0001), alcohol (P = 0.0003), and NSAID (P = 0.0088) consumption. DU patients taking antiplatelet drugs have significantly better results after four weeks and worse results after eight weeks (P = 0.0352).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 0.5 g daily dose of cimetidine was as effective as a 1 g dose in the acute treatment of duodenal ulcer patients in Hong Kong. The aims of the present study were, first, to determine whether low-dose cimetidine treatment was as effective as standard doses in acute duodenal ulcer treatment of patients in Singapore, and second, to compare a single nocturnal dosage regimen with a twice daily regimen. In this single centre, double-blind, controlled trial, 282 patients with endoscopically proven duodenal ulcer were randomized to receive four weeks' treatment with cimetidine using one of three dosage regimens: (A) 800 mg at night; (B) 400 mg at night; or (C) 400 mg twice daily. Two hundred and forty-seven patients were evaluated. The incidences of healing at four weeks were: (A) 40/80 (50%), (B) 39/88 (44%); and (C) 48/79 (61%); (B vs C: P less than 0.05; A vs C: NS; 95% confidence limits: -5% to 27%; A vs B: NS, 95% confidence limits: -6% to 21%). Of 183 patients who had antral biopsies taken, 176 (96%) had histological gastritis, while 167 (91%) were positive for Helicobacter-like organisms. The occurrence of gastritis or Helicobacter-like organisms had no influence on ulcer healing. A 400 mg dose of cimetidine is therefore suboptimal for the treatment of duodenal ulcer in patients in Singapore. A single nocturnal dosage regimen may be less effective than a twice daily regimen.

Abstract
We have determined the relative importance of day and night time gastric acid inhibition for duodenal ulcer healing by comparing the anti-ulcer efficacy of a single morning with that of a single bedtime dose of ranitidine. One hundred and thirty patients with active duodenal ulcer were randomly assigned to a double-blind therapy with ranitidine 300 mg at 8 am or the same dose at 10 pm for up to eight weeks. The antisecretory effects of these regimens were also assessed by 24 h intragastric pH monitoring in 18 of these patients. At four weeks ulcers had healed in 41/61 (67%) of patients taking the morning dose and in 47/63 (75%) of those receiving the nocturnal dose (95% CI for the difference -0.09 +0.25; p ns). At eight weeks, the corresponding healing rates were 82% and 85.5%, respectively (95% CI for the difference -0.11 +0.17; p ns). Both treatments were significantly superior to placebo in raising 24 h intragastric pH, although the effects of the morning dose were of shorter duration than those of the nocturnal dose. These findings suggest that suppression of nocturnal acidity is important but not essential to promote healing of duodenal ulcers; a prolonged period of acid inhibition during the day (as obtained with a single large morning dose of H2-blockers) may be equally effective.

Abstract
Both meal-stimulated and nocturnal acid secretions have been shown to be abnormally increased in patients with duodenal ulcer. The relative efficacy of an acid-reducing regimen aimed specifically at controlling postprandial acid secretion compared with one that controls nocturnal acid secretion is, however, not known. The endoscopic healing rates at weeks 2, 4, 6, 8, 10, and 12 of three cimetidine regimens with identical total daily dose--bedtime (1200 mg), mealtime (400 mg three times a day with meals), and reference (200 mg three times a day with meals and 600 mg at bedtime)--were compared in a randomized study on 141 patients with endoscopically proven duodenal ulcer. Evaluating endoscopists were blinded to patients' form and duration of treatment and their clinical progress; patients were unaware of the comparative design of the study. Life-table analysis for the 12 weeks of observation revealed that the mealtime regimen resulted in significantly (P less than 0.05) better healing rates than either the bedtime or the reference regimen. The differences were accounted for largely by the significantly (P less than 0.04) better healing rate at two weeks with the mealtime regimen (68%) than with either the bedtime (47%) or the reference (45%) regimen. These findings indicate that a regimen that aims at controlling meal-stimulated acid secretion achieves a faster healing rate than one that aims at controlling nocturnal acid secretion in the treatment of duodenal ulcer, and they suggest that postprandial acid secretion plays a greater role than nocturnal acid secretion in the pathophysiology of this condition.

Abstract
Patients with duodenal ulcer (DU) were classified into responders to H2-antagonist and non-responders in whom DU did not heal within 3 months with the antagonist. In these patients and healthy controls, a modified sham-feeding (MSF) test was performed to elucidate the pathogenesis of resistance to H2-antagonist. By MSF stimulation, gastric acid secretion significantly increased in all subjects. The mean acid output by MSF amounted to about 52 of the tetra-gastrin maximum in controls (12 cases), 46% in responders (12 cases) and 72% in non-responders (14 cases). The mean acid output in non-responders was significantly higher than in controls under baseline conditions, MSF and gastrin stimulations, but was higher than in responders during MSF stimulation. The effects of H2-antagonist (cimetidine 1mg/kg/h), anti-muscarinic agent (pirenzepine 0.3mg/kg/h), or both on the acid secretion were examined on non-responders (6 cases), responders (6 cases) and healthy controls (6 cases). The acid secretion stimulated by MSF was significantly inhibited by pirenzepine in responders and controls, but not in non-responders. With cimetidine, the acid output was significantly inhibited in all groups, but was still higher in non-responders than in controls and responders, indicating that the reduction of acid output by a H2-antagonist is significantly less in non-responders than in other groups. The combined use of pirenzepine and cimetidine almost completely inhibited the acid output in all groups. These data suggest that the vagal activity in non-responders to H2-antagonist is higher than in responders and healthy subjects, and H2-antagonist combined with anti-muscarinic agent is more effective in reducing the gastric acid secretion in non-responders.

Abstract
The aim of this study was to compare the duodenal ulcer healing effects of morning (08.00 hours) vs. single bedtime (22.00 hours) doses of 40 mg famotidine, bearing in mind that the known efficacy of bedtime doses of H2-antagonists is regarded as evidence of the predominance of nocturnal gastric acidity in the pathogenesis of duodenal ulcer. This randomized double-blind multicentre trial was conducted in a total of 127 patients with endoscopically proven active duodenal ulcer. Nine patients dropped out and thus 118 were included in the final analysis. The duration of treatment was 4 weeks, and this was extended to 8 weeks in patients whose ulcers failed to heal by week 4. The patients in the two treatment groups were well matched for age and sex. The therapeutic efficacy parameters were endoscopic healing of the ulcer lesion and disappearance of pain. Results were compared using the chi-square method. The 4- and 8-week (cumulative) ulcer healing rates in the patients treated with the morning dose of famotidine were 77.2% and 86%, respectively, compared with 78.6% and 91.8% in those who received the bedtime dose. The differences failed to prove statistically significant either at week 4 (P = 0.85) or at week 8 (P = 0.31). The percentages of patients with ulcer pain, evaluated weekly, were similar in the two treatment groups. The equivalent efficacy of the morning and bedtime famotidine regimens raises doubts concerning the predominance of nocturnal gastric acidity in the pathogenesis of duodenal ulcer.

Abstract
It has not been established whether multiple duodenal ulcer is associated with a different natural history, pathophysiology, and therapeutic response than a single duodenal ulcer. A consecutive series of 96 patients with two or more duodenal ulcers at endoscopy, representing 9.6% of the total number of new patients with duodenal ulcer seen during the period 1980-1985, were compared with a random series of 200 patients with single duodenal ulcer seen in the middle years of this period. Multiple duodenal ulcer was associated with higher (p less than 0.02) male to female ratio, more (p less than 0.05) late onset patients (those with ulcer symptoms starting after age 30 years, more (p less than 0.05) chronic cigarette smokers, and more frequent (p less than 0.05) moderate to severe deformity of the duodenal bulb. More (p less than 0.05) patients with multiple duodenal ulcer had abnormally low D50 derived from pentagastrin dose response tests, indicating that they were more sensitive to gastrin stimulation. Furthermore, their mean fasting and meal stimulated serum gastrin concentrations were significantly higher than those of patients with single ulcer (p less than 0.005), or of controls (p less than 0.05). Compared with single duodenal ulcer, multiple ulcer had significantly lower placebo healing rate, and required a higher dose of misoprostol (1200 v 800 micrograms/day) to achieve a similar healing efficacy at four weeks. We conclude that multiple duodenal ulcer is associated with different clinical features, pathophysiology, and possibly therapeutic response from single duodenal ulcer, and appears to represent the more aggressive side of the ulcer spectrum.

Abstract
Suppression of gastric acid forms the basis of treatment of duodenal and gastric ulcer, but the precise relationship between suppression of acidity and healing rates has not been defined. We examined the results of controlled trials and clinical pharmacological studies of 24-h intragastric acidity involving antisecretory agents. Data on 24-h and nocturnal hydrogen ion activity and nocturnal acid output were obtained, and the healing rates in duodenal ulcer were calculated. Duodenal ulcer healing rates after 4 weeks showed a significant correlation with suppression of 24-hour hydrogen ion activity (r = 0.63; P less than 0.05), and a highly significant correlation between healing and the suppression of nocturnal hydrogen ion activity (r = 0.93; P less than 0.0001). Nocturnal acid output was not significantly correlated. For gastric ulcer, no such association was seen for suppression of either 24-hour or nocturnal hydrogen ion activity. Duodenal ulcer is regarded as an acid-related disorder, but in gastric ulcer other factors may be more important in pathogenesis and treatment.
