Gastric and duodenal ulcer in the same patient.

UNLABELLED: No extensive endoscopic studies have been performed on the prevalence and the clinical outcome of association of gastric ulcer (GU) and duodenal ulcer (DU). The present investigation, partially retrospective and partially prospective, takes into account 715 patients with active ulcer demonstrated by endoscopy, followed-up for a mean period of 3.8-years; 23 of them (3.2%) were found to have synchronous or asynchronous gastric and duodenal ulcers. The following characteristics were investigated: age of onset of both diseases, ulcer family history, cigarette and alcohol consumption, nonsteroidal anti-inflammatory drugs abuse, serum pepsinogen group I, ABO and Lewis blood groups, healing and relapse rate under H2-blocker treatment. The first diagnosis (by either X-Ray or endoscopy) was DU in 500 subjects (70%), GU in 210 (29.3%) and synchronous gastric and duodenal ulcers in 5 (0.7%). After a median period of 10 years, 2.8% of DU patients developed a GU; after 2-12 yrs 1.9% of GU patients developed a DU. The clinical and biochemical findings of our GU/DU patients suggest that the two ulcers are related by chance. IN CONCLUSION: asynchronous GU/DU patients do not seem to have a distinct disease in the large spectrum of ulcer disease. Larger studies must be planned on synchronous GU/DU with the aim of assessing whether or not it represents a particular type of ulcer disease.

Fibergastroscopic study of early and advanced gastric cancer in a series of 8,000 consecutive patients.

Eight cases of early gastric cancer (EGC) (histological diagnosis on the resected specimens) were detected Type III (excavated; seven out of eight cases). In three endoscopies. They constituted 3.3% of the gastric cancers observed (239 cases). The most frequent type of EGC was Type III (excavated: seven out of eight cases). In three patients the diagnosis was made only at a second examination, since the first had been negative for malignancy; at the follow-up examination in these cases, the lesion seemed to have healed. The operation was therefore carried out only on the basis of the histological interpretation of endoscopic biopsies.

The efficacy of two doses of omeprazole for short- and long-term peptic ulcer treatment in the elderly.

This study evaluated the efficacy, safety, and most suitable dose of omeprazole in short-term acute treatment (4 weeks) and maintenance treatment (6 months) of patients older than 60 years of age with endoscopically diagnosed gastric ulcer (GU) or duodenal ulcer (DU). This randomized, prospective study included 156 patients (67 GU and 89 DU; mean age, 74.8 and 72.3 years, respectively) who were randomized in the acute phase into two treatment groups: omeprazole 20 mg/d or 40 mg/d as a single morning dose for 4 weeks. The 6-month follow-up phase included 101 patients who were randomized to receive omeprazole 20 mg/d or 20 mg every other day. After 4 weeks of treatment, 94.0% of GU patients and 95.5% of DU patients showed complete ulcer scarring with no statistical differences between doses. At the end of the 6-month follow-up, 4.5% of GU patients and 8.8% of DU patients relapsed, with no statistical differences between groups. No clinically significant adverse events were recorded. In conclusion, omeprazole is a highly effective, well-tolerated, and safe drug for the short- and long-term treatment of GU and DU in the elderly. The dose of 20 mg/d for the acute phase and 20 mg on alternate days for maintenance therapy appears most appropriate for elderly patients with ulcers.

Risk factors of duodenal ulcer bleeding: the role of smoking and nicotine.

Several studies have shown that cigarette smoking affects duodenal ulcer (DU) recurrence. To verify any correlation between smoking and complications of ulcer disease, we studied 33 DU smokers, 16 DU ex-smokers and 87 DU non-smokers for up to 48 months, recording age, sex, family history of ulcer, ulcer symptoms, non-steroidal anti-inflammatory drug use, length of DU history, alcohol consumption, smoking habit, relapses and bleeding episodes. Nicotine contents were also obtained for the type of cigarettes smoked. Statistics used were: Analysis of variance with Bonferroni's test. Pearson's chi-squared test and stepwise logistic regression analysis. Smokers were found to have significantly more relapses but fewer bleeding episodes than ex-smokers and non-smokers (63.3%, 31.2% and 34.5%, p = 0.029; 12.1%, 43.7% and 34.5%, p = 0.017). Bleeders were significantly more often males than non-bleeders (82.9% vs. 61.0%, p = 0.01) and had ulcer symptoms less frequently (9.7% vs. 26.3%, p = 0.02). Multivariate analysis confirmed sex as a risk factor (OR = 3.0) and smoking as a "protective" factor (OR = 0.4) for bleeding, while nicotine intake was found to be unrelated to this complication. We concluded that smoking (but not nicotine intake) and male sex are factors to take into account in evaluating the risk of DU bleeding.

High IgE serum levels and "peptic" ulcers: clinical and functional approach.

The prevalence of high total IgE serum levels was evaluated in 232 consecutive patients suffering from peptic ulcer. Twenty-one percent of the patients presented total IgE serum levels above 200 KU/L compared with the 5% found in a healthy control population (p < 0.004). Similar prevalence was found in gastric and/or duodenal ulcers. No significant differences in the duration of the disease, smoking habits, familiarity for peptic ulcer, symptomatology and frequency of complications were observed between patients with high and with normal total IgE serum levels. Gastric function studies (gastric acid secretion, serum pepsinogen and gastrin levels) did not show any significant differences between the two groups. The incidence of Helicobacter pylori infection was 65% in patients with normal IgE levels and 75% in those with high IgE levels (p: n.s.). The response to treatment with full dose of H2-receptor antagonists was comparable in both groups (91.25% and 90.7% of ulcer healing after 6-8 weeks of treatment). A relapse of the ulcer after 6 months of maintenance therapy (half dose of H2-receptor antagonists) was observed in 39.5% of the patients with ulcer and high total IgE serum as against the 11.9% observed in patients with normal IgE (p < 0.001). These data lend further support to the hypothesis of an underlying immuno-allergic reaction in some forms of gastric or duodenal ulcer.

Effects of H2 blockers and omeprazole on peptic secretion: a prospective, randomized study in duodenal ulcer subjects.

UNLABELLED: Aim of the present study has been to investigate the possible modifications of peptic secretion after a period with H2 blockers and omeprazole, evaluating in the same patient pepsinogen group A levels in gastric mucosa and pepsin in gastric juice. 54 active duodenal ulcer were studied: during an upper gastrointestinal endoscopy a sample of gastric juice and one fundus biopsy were taken before and after four weeks 300 mg/daily ranitidine (23 patients), 40 mg/daily famotidine (7 patients), 300 mg/daily nizatidine (12 patients) therapy and 40 mg/daily omeprazole (12 patients) therapy. RESULTS: H2-blockers and omeprazole treatment determines a non statistically significant decrease of pepsin in gastric juice and in pepsinogen group A in gastric mucosa.

Biochemical and histopathological aspects in duodenogastric reflux gastritis patients with or without prior cholecystectomy.

The aim of this study was to evaluate some biochemical and histopathological aspects in a group of patients with a view to identifying any differences depending on whether the pathology was associated with previous cholecystectomy or idiopathic. The study involved 23 patients (8 post-cholecystectomy cases and 15 ulcer-free dyspeptic patients) with the diagnosis of duodenogastric reflux gastritis confirmed by endoscopic histopathological evaluation. The following parameters were considered: 1. pH and bile salt concentration in gastric juice; 2. histological classification of antral biopsies (Niemela's criteria); 3. dyspeptic symptoms (dyspepsia, pyrosis and epigastric pain, sense of repletion, foul-tasting mouth) graded on a scale from 0 to 4. All parameters were considered in relation to whether or not Helicobacter Pylori was found in the histological specimens. No significant differences were found between the two groups for pH and bile salt values or for Helicobacter Pylori positivity. No relationship was observed between the Helicobacter Pylori and either the severity of the histological picture, the features of the biochemical parameters or the severity of the clinical symptoms. Such findings confirm the common pathophysiological pattern of reflux gastritis regardless of any permanent biliary tract alterations and the low importance of Helicobacter Pylori infection in determining this syndrome.
