ABSTRACT

PURPOSE: The purpose of this study was to compare the efficacy of proton pump inhibitor (PPI) with H(2) receptor antagonist (H(2)RA) in treatment of upper abdominal symptoms. METHODS: This was a multi-center, open study conducted at 102 hospitals in Japan. Patients with reflux esophagitis received famotidine 10 mg twice daily for 2 weeks, then omeprazole 10 mg once daily for 2 weeks. Thereafter, patients were switched to famotidine 10 mg twice daily for a third 2-weekperiod, provided those with a medical condition agreed to continue the study. Patients evaluated the treatment response to each gastrointestinal symptom using a predefined patient questionnaire and gastrointestinal symptom rating scale (GSRS). RESULTS: 161 patients entered the study, of whom 8 were excluded from all analyses due to lack of participation following entry. Overall symptom improvement rate (n = 130) at week 4, after the 2-week omeprazole treatment, was 75.4% and this was significantly higher than that after the first 2-week famotidine treatment (41.5%) at week 2. In patients (n = 36) who completed 6 weeks of treatment, 2-week omeprazole treatment at week 4 showed a significantly higher overall symptom improvement rate compared with both the first 2-week and third 2-week famotidine treatments. CONCLUSIONS: Omeprazole was superior to famotidine for treatment of upper abdominal symptoms in patients with reflux esophagitis, which suggested that gastric acid might be a cause not only of reflux symptoms, but also of ulcer symptoms and dysmotility symptoms such as epigastric pain and feeling of fullness in reflux esophagitis.

ABSTRACT

BACKGROUND AND AIM: Helicobacter pylori infection and non-steroidal anti-inflammatory drugs (NSAIDs) are deeply involved in the etiology of gastric ulcers. The aim of our study was to clarify the endoscopic characteristics and H. pylori infection status of NSAID-associated gastric ulcers. METHODS: The study group comprised 50 patients (23 men, 27 women; mean age 66.5 years) with NSAID-associated gastric ulcers and 100 sex- and age-matched patients with gastric ulcer associated with other factors (control group). Ulcer morphology, size and number of lesions, onset site and incidence of hemorrhagic ulcers were investigated endoscopically in both groups. H. pylori infection was diagnosed by serology, histology and (13)C-urea breath test. RESULTS: Multiple lesions (68% vs 20%, P<0.001), occurrence in the antrum (56% vs 6%, P<0.001), and hemorrhagic ulcer (34% vs 4%, P<0.001) were significantly more prevalent in patients with NSAID-associated gastric ulcers than in patients with non-NSAID-associated gastric ulcer. The H. pylori infection rate was significantly lower in NSAID-associated gastric ulcer patients than in non-NSAID-associated gastric ulcer patients (48% vs 96%, P<0.001). In the NSAID-associated gastric ulcer group, the prevalence of H. pylori infection was significantly lower in patients with ulcers in the antrum than in those with ulcers in the angulus or corpus (25% vs 77.3%, P<0.001). CONCLUSIONS: In contrast to non-NSAID-associated gastric ulcers, NSAID-associated gastric ulcers frequently occur in the antrum with bleeding. The rate of H. pylori infection in NSAID-associated gastric ulcers is significantly lower than that in non-NSAID-associated gastric ulcers.

ABSTRACT

BACKGROUND AND AIM: Many studies have shown that Helicobacter pylori infection is associated with chronic gastritis, peptic ulcers and gastric carcinoma in adults. However, little is known about these associations in the younger population. The aim of this study was to clarify endoscopic and histological findings in H. pylori-positive young adults. METHODS: Two hundred consecutive outpatients younger than 29 years old undergoing esophago-gastroduodenal endoscopy at four hospitals between 2001 and 2002 were eligible for this study. At endoscopy, three biopsy specimens were obtained from the mid-antrum, the angulus and the mid-corpus. Endoscopic and histological interpretations were based on the updated Sydney System. H. pylori infection was determined by histology and serology. RESULTS: The rates of H. pylori infection were 1.2% (1/86) in normal, 95.8% (46/48) in gastritis, 97.8% (45/46) in duodenal ulcers, 100% (17/17) in gastric ulcers, and 100% (3/3) in gastric carcinomas. Endoscopic findings in 112 H. pylori-positive patients were 25 normal (22.3%), 38 atrophy (33.9%), 18 erosion (16.1%), and 31 nodularity (27.7%). Histological findings of H. pylori-positive patients in the anturm revealed mononuclear cell and neutrophil infiltration in 100%, and atrophy in 27.7%. Histological findings of H. pylori-positive patients in the corpus revealed mononuclear cell infiltration in 75%, neutrophil infiltration in 60.7%, and atrophy in 28.6%. CONCLUSIONS: The study shows that H. pylori infection is strongly associated with chronic gastritis and peptic ulcers, and that histological corpus gastritis was found with high frequency in Japanese young adults.
