Psychological correlates of gastric and duodenal ulcer disease

Psychological correlates of gastric and duodenal ulcer disease were assessed in a group of somewhat older patients with ulcer disease identified by endoscopy. Associations between both ulcer types and symptom measures (anxiety and depression) seemed only to reflect severity or chronicity of gastrointestinal symptoms or the impending endoscopy procedure. Associations with 'trait' psychological indices may be of causal significance. Duodenal ulcer patients had higher 'introversion' and 'psychoticism' scores (on the EPQ) than controls, while gastric ulcer patients had higher psychoticism scores and 'trait anxiety' scores. These findings could not be attributed to confounding variables. When the two ulcer groups were compared, the gastric ulcer group had significantly higher neuroticism, psychoticism and hostility scores which were not attributable to confounding variables. The higher depression scores in gastric ulcer patients, however, simply reflected the greater chronicity of their physical symptoms. The groups did not differ significantly on measures of trait anxiety, tension, introversion or Type A behaviour.     

Improved use of the [13C]octanoic acid breath test as intra-individual parameter to study the effect of a prokinetic drug on gastric emptying in preterm infants with oral feeding intolerance

The [13C]octanoic acid breath test was used for the measurement of differences in gastric emptying in preterm infants for the evaluation of pharmacological therapy. In order to perform a good intra-individual comparison of the gastric emptying in preterm infants under non-standardisable test conditions, we adjusted t1/2 for variations in non-recovered label (=label retention) and introduced an "effective half 13CO2 breath excretion time" t1/2eff = t1/2/m expressed as min per percentage of the cumulative dose recovered. In a pilot study, we investigated the action of the gastrointestinal prokinetic drug cisapride on gastric emptying in seven premature infants, of whom four suffered from gastric stasis and three had constipation. The postnatal age and weight at the start of treatment ranged from 15 to 64 days and from 815 to 1635 g, respectively. All infants received the standard formula for premature infants (Nenatal, Nutricia). Cisapride was administered orally 0.2 mg/kg, four times daily. The changes in gastrointestinal motility were studied using the total bowel transit time of carmine red. After 7 days of treatment in all children, the gastric emptying coefficient and the half 13CO2 breath excretion time adjusted for label retention were improved (n=7, the gastric emptying coefficient range before treatment was 1.69-3.34 (mean 2.59 +/- 0.80) and after treatment it was 2.79-3.76 (mean 3.28 +/- 0.30); the half 13CO2 breath excretion time adjusted for label retention range before treatment was 3.0-14.7 min/% dose (mean 7.0 +/- 5.0) and after treatment 2.6-4.0 min/% dose (mean 3.1 +/- 0.6). The total bowel transit time was only slightly improved in two patients (n=7, mean total bowel transit time before: 23.7 h compared to mean total bowel transit time after 7 days of treatment: 35.5 h). Side effects during cisapride treatment were not seen. We conclude that in premature infants cisapride is effective in shortening gastric emptying time and reducing gastric stasis; the therapeutic role in constipation has to be further investigated.     

Histamine and peptic ulcer: A prospective study of mucosal histamine concentration in duodenal ulcer patients and in control subjects suffering from various gastrointestinal diseases

Summary In a prospective study the histamine content of the mucosa of the body of the stomach was measured in 100 patients consisting of control subjects, patients with duodenal ulcer and patients suffering from various gastrointestinal diseases. The histamine content was found to be 43 µg/g in male control subjects (median) while in duodenal ulcer patients levels attained were significantly lower by about 30 per cent. In all the other groups of patients histamine concentrations in gastric mucosa were found to be normal. Since in most species it is extremely difficult to alter the mucosal histamine concentration by any form of treatment, the diminished histamine content of the gastric mucosa in patients with duodenal ulcer seems remarkable. Among several possible explanations offered for this finding we think the most likely is that histamine release is increased in duodenal ulcer disease.Supported by the Deutsche Forschungsgemeinschaft (Lo 199/5)     

Gastritis, intestinal metaplasia and dysplasia versus benign ulcer in stomach and duodenum and gastric carcinoma -- a histotopographical study.

In histological examination of gastrectomy specimens from patients with duodenal ulcer, gastric ulcer, and early and advanced cancer, both chronic atrophic gastritis and intestinal metaplasia were identified in 54% of the cases with duodenal ulcer. At 90 to 100%, respectively, these mucosal changes were approximately twice as frequent with gastric ulcer and early and advanced gastric cancer. Mild dysplasia occurred in 54% of the cases with duodenal ulcer; occurred somewhat more frequently with gastric ulcer, in 75% of the cases; and in almost all cases with early and advanced gastric cancer, at 90% and 100%, respectively. Whereas 27% of the cases with duodenal ulcer, 62% with gastric ulcer, and 90% and 95% of the respective cases with early and advanced gastric cancer showed moderate dysplasia, only severe dysplasia in early gastric cancer (40%) and advanced gastric (81%) was clearly more frequent in comparison to duodenal ulcer (9%) and gastric ulcer (12%). In the cases with duodenal ulcer chronic atrophic gastritis and intestinal metaplasia were limited mostly to the antrum; with gastric ulcer and cancerous stomach disorders, they also occurred in other stomach sections. Mild and moderate dysplasia conformed to the same distribution pattern. Severe dysplasia, which was only detected in two ulcer cases, was not only substantially more frequent in cases with early and advanced gastric cancer, but also showed a clear topographic relationship to cancer localization in the stomach.     

Factors associated with gastro-duodenal disease in patients undergoing upper GI endoscopy at the Korle-Bu Teaching Hospital,Accra, Ghana

BackgroundThere is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 — 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana.ObjectivesThis study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana.MethodsThis study utilized a cross-sectional design to consecutively recruit patients referred with upper gastro-intestinal symptoms for endoscopy. The study questionnaire was administered to study participants. Helicobacter pylori infection was confirmed by rapid-urease examination at endoscopy.ResultsOf 242 patients sampled; 64 had duodenal ulcer, 66 gastric ulcer, 27gastric cancer and 64 non-ulcer dyspepsia. Nineteen (19) had duodenal and gastric ulcer while 2 had gastric ulcer and cancer. A third (32.6%) of patients had history of NSAID-use. H. pyloriwas associated with gastric ulcer (p=0.033) and duodenal ulcer (p=0.001). There was an increased prevalence of duodenal ulcer in H. pylori-infected patients taking NSAIDs, P=0.003.ConclusionH. pylori was a major risk factor for peptic ulcer disease. However, NSAID-related gastro-duodenal injury has been shown to be common in H. pylori infected patients. It highlights the need for awareness of the adverse gastro-intestinal effects in a H. pylori endemic area.     

Detection of Campylobacter pyloridis in patients with antrum gastritis and peptic ulcers by culture, complement fixation test, and immunoblot.

The association of Campylobacter pyloridis with antrum gastritis and peptic ulcers was described. We investigated antral biopsies from 180 patients who underwent gastroscopy. By culture or Gram stain or both, we found overall 98 (54%) of them to be positive for C. pyloridis. In the various groups the following percentages were found to be positive: normal antral mucosa 3% (n = 30); moderate superficial antrum gastritis, 49% (n = 83); severe superficial antrum gastritis, 86% (n = 44); duodenal ulcer, 83% (n = 54); and gastric ulcer, 72% (n = 18). A serological screening that used a complement fixation test yielded the following results: highest rates of positive complement fixation titers were seen in patients with severe gastritis and those with duodenal ulcers, both with 79%; the lowest incidence was in a group of 20 blood donors, with 5%. Positive complement fixation titers in gastritis patients also correlated well with characteristic patterns on immunoglobulin G and A immunoblots, while there was no specific reactivity observed on immunoglobulin M immunoblots.     

CLINICO-PATHOLOGICAL STUDY OF GASTRO-DUODENAL ULCERS FROM THE STANDPOINT OF AGING OF THE PATIENTS

The gastric ulcer and duodenal ulcer resected surgically were Investigated clinico-pathologically. The duodenal ulcers occurred frequently in the third to fourth decades in the patients with relatively normal gastric mucosal structure and high acid secretion. On the other hand, the gastric ulcer occurred frequently in the fifth to sixth decades in the patients with moderate to marked mucosal damage and subsequent intestinal metaplasia. Although the duodenal ulcers occurred frequently in the anterior wall, the gastric ulcers were usually found in the lesser curvature and posterior wall. Multiple lesions in the patients of gastric ulcer and linear lesion in the patients of duodenal ulcer increase by aging. The duodenal ulcers were found at the rate of 25% in the patients with gastric ulcer and the gastric ulcers were found at the rate of 40% in the patients with duodenal ulcer.

Assessment of gastric emptying and duodenal motility upon ingestion of a liquid meal using rapid magnetic resonance imaging

Gastric emptying is achieved by co-operation between gastric and duodenal motor activity. Therefore, evaluation of gastric emptying and its associated mechanisms would benefit clinical therapy as well as medical research. Healthy volunteers underwent rapid magnetic resonance imaging (MRI) of the abdomen along the coronal plane after ingestion of a liquid meal. The gastric fundal and duodenal areas were quantified semi-automatically by self-developed segment software. The average gastric fundal area determined by the serosal end in 40 sequential images was reduced to ～81% 30 min after and to ～70% 60 min after ingestion of a liquid meal. The average duodenal area also decreased to ～86% after 30 min and to 83% after 60 min. In contrast, changes in the centre of gravity increased to about fivefold after 30 min and to about threefold after 60 min. The mean velocity of the duodenal wall mimicked changes in the centre of gravity. The application of metoclopramide, a dopamine D(2) receptor antagonist, accelerated gastric emptying, presumably due to facilitated duodenal activity even immediately after liquid meal ingestion. The ingestion of water caused fast gastric emptying in 30 min, accompanied by high duodenal motility, but it ceased after 60 min, presumably reflecting complete gastric emptying. A rapid MRI scan visualized the association between gastric emptying and duodenal motility that could be modified by calories and dopaminergic neurotransmission. Changes in the centre of gravity and mean velocity of the duodenal wall appear to quantify the motility obtained from cine MRI accurately.     

Histological study of chronic gastritis from the United Arab Emirates using the Sydney system of classification.

AIMS--To determine the prevalence of Helicobacter pylori in five main nationality groups with gastric ulcer, duodenal ulcer, and non-ulcer dyspepsia; and to determine the histopathological types of gastritis and assess the graded variables of Helicobacter associated gastritis. METHODS--Gastric antral and corpus biopsy specimens from 437 patients were examined for the prevalence of H pylori, 337 of which were classified and graded histologically according to the Sydney system. RESULTS--The overall colonisation rate of H pylori was 90%, and there was no significant difference between groups of different ethnic origins. The colonisation rates were 99%, 89%, and 78% in patients with duodenal ulcer, non-ulcer dyspepsia, and gastric ulcer, respectively. Helicobacter associated gastritis was the most common form of chronic gastritis (87%). H pylori density was greater in the antrum than the body. Gastric atrophy in helicobacter associated gastritis was seen in 54% of the cases (43% grade I, 10% grade II, 1% grade III) and increased the older the patients. Atrophy of the corpus alone was very rare (1%). Atrophy and intestinal metaplasia were more prevalent in patients with gastric ulcer than duodenal ulcer. CONCLUSION--The colonisation rate of H pylori was similar in the five groups studied and was almost invariably present in gastric biopsy specimens in patients with duodenal ulcer. H pylori associated gastritis was the most common form of gastritis. Atrophy was mainly of low grade and increased the older the patient.

Medical treatment of gastric and duodenal ulcer

Summary Antacids prove ready if only temporary relief of the symptoms of ulcers. Physicians have been able to increase the rate of healing of gastric ulcers by advising patients to stop smoking and then either admit them to hospital for bed-rest, or use carbenoxolone sodium as an outpatient therapy. The early trials of some other drugs have shown increase in rate of healing of gastric ulcer, but there is no medical treatment which will prevent the high recurrence rate of benign gastric ulcer. The limited data indicate that adequate medical reduction in acid secretion and enhancement of mucosal resistance may benefit patients with duodenal ulcer.Presented at the meeting on Gastric and duodenal ulcer disease: Basic principles and clinics of treatment by drugs and operations, Marburg, November 22, 1975     

Differing degree and distribution of gastritis in Helicobacter pylori-associated diseases

Infection with Helicobacter pylori (H. pylori) causes gastritis, and may be associated with gastric and duodenal ulcers and also with such malignant diseases as MALT lymphoma and gastric carcinoma. In order to determine whether there are differences in the degree and distribution of gastritis, each patient with H. pylori gastritis only (n = 50) was matched for sex and age with four patients, one each with H. pylori-associated duodenal ulcer, gastric ulcer, gastric carcinoma or MALT lymphoma. From each patient, two biopsies were taken from the antrum and two from the corpus for histopathological examination of H. pylori gastritis. The median summed gastritis score decreases in the following order: antrum: gastric ulcer > duodenal ulcer > gastritis alone > carcinoma > MALT lymphoma, and corpus: gastric ulcer > carcinoma > MALT lymphoma > gastritis alone and duodenal ulcer. We conclude that the degree and distribution of H. pylori gastritis differs significantly among H. pylori-associated diseases. These differences may explain some of the underlying pathomechanisms associated with H. pylori infection.

Implications for a role of interleukin‐23 in the pathogenesis of chronic gastritis and of peptic ulcer disease

The present study aimed to investigate the role of gastric mucosa for the secretion of interleukin (IL)‐23 in chronic gastritis. One hundred and one patients were enrolled; 47 with duodenal ulcer, 33 with gastric ulcer and 31 with chronic gastritis. Biopsies were incubated in the absence/presence of endotoxins. Supernatants were collected and IL‐23 and IL‐1β were measured by enzyme‐linked immunosorbent assay. Scoring of gastritis was performed according to the updated Sydney score. Patients with duodenal and gastric ulcer and those with chronic gastritis had similar scores of gastritis. IL‐23 was higher in supernatants of tissue samples of Helicobacter pylori‐positive than of H. pylori‐negative patients. No differences were recorded in concentrations of IL‐23 and IL‐1β between patients with duodenal ulcer, gastric ulcer and chronic gastritis. Positive correlations were found between IL‐23 of patients with both duodenal and gastric ulcer and chronic gastritis and the degree of infiltration of neutrophils and monocytes. Similar correlations were observed between IL‐23 and IL‐1β. IL‐23 secreted by the gastric mucosa could be implicated in the pathogenesis of chronic gastritis. IL‐23 was released in the presence of H. pylori from the inflamed gastric mucosa and followed the kinetics of IL‐1β.     

Duodenal ulcer with gastrin cell hyperplasia--a special form of peptic ulcer

Pap test was used to study gastric and duodenal G and D cells, blood gastrin levels, basal and stimulated acid production, clinical manifestations, and morphological characteristics of the mucosa in 39 patients with duodenal ulcer and 13 controls. The findings enable the authors to outline a special form of peptic ulcer that is characterized by gastrin cellular hyperplasia concurrent with relative pyloric D cell deficit, gastric metaplasia in the duodenum and gastric hypersecretion. Such patients have more frequently multiple ulcers, predominantly 0(I) blood group, complication-aggravated course of the disease, and ulcer history in close relatives. Moreover, it has been demonstrated that incidence of gastric metaplasia is due to gastric hypersecretion; hyperplasia of duodenal gastrin cells is associated with incidence of gastric metaplasia in patients with peptic ulcer.     

Antral gastrin-producing G-cells and somatostatin-producing D-cells in peptic ulcer

Summary The number of G cells and D cells per area unit and the G cell/D cell ratio was studied in control subjects and patients with duodenal or gastric ulcer. A great inter-individual variation in the population density of both types of cells was observed in the three groups studied. G cell density was significantly decreased in both duodenal and gastric ulcer patients, when compared with controls; whereas no difference in G cell density was seen between duodenal ulcer patients and gastric ulcer patients. However, D cell density was significantly decreased in duodenal ulcer patients when compared with control subjects and gastric ulcer patients. In this latter group, D cell density was also lower than in control subjects. A significant positive linear correlation between G cell number and D cell number was found in the three groups studied. The G cell/D cell ratio was significantly increased in duodenal and gastric ulcer patients when compared with controls. This was mainly due to a decrease in D cell numbers. It is concluded that a local deficit in antral D cells in patients with peptic ulcer may favor the pathogenesis of ulcer disease.     

vacA genotypes in Helicobacter pylori strains isolated from children with and without duodenal ulcer in Brazil

Data concerning the association between vacA genotypes and disease in children in both developed and developing countries are scarce, especially because of the small number of children with a duodenal ulcer studied. The vacA genotypes of Helicobacter pylori strains obtained from 65 children (24 with a duodenal ulcer and 41 without a duodenal ulcer; 33 girls; mean age, 10.2 years; age range, 1 to 17 years) were investigated as described by J. C. Atherton et al. (J. Clin. Microbiol. 37:2979-2982, 1999). Ten (15.4%) children were infected with more than one H. pylori strain. None of these patients were included in our analysis of the relationship between gastric disorders and specific vacA genotypes. The s1 allele was detected in all H. pylori strains isolated from patients with a duodenal ulcer and from 21 (58.3%) patients without a duodenal ulcer (P = 0.003). Strains with the s2 allele were found only in patients without ulcer (n = 15; 41.7%). Most s1 strains had the s1b allele (97.5%), a result similar to that reported for adults from the Iberian peninsula, which could reflect the Brazilian population origin. One untypeable s1 strain was isolated. The m1 allele was also more frequently found in strains obtained from duodenal ulcer patients (P = 0.028). The m2 allele was found in strains obtained from 20 (36. 4%) children, 3 (15.8%) with an ulcer and 17 (47.2%) without an ulcer. Only one m hybrid strain (m1 and m2 hybrid) was detected. It was demonstrated for the first time that the frequencies of colonization with strains with the s1 allele (14.3% in children up to 8 years of age and 85.7% in older patients; P = 0.012) and of strains with the m1 allele (11.1% in patients up to the age 8 years and 88.9% in older children; P = 0.013) increase with age.     

Physiopathology of Helicobacter pylori infections

Helicobacter pylori (H.p.) causes active chronic gastritis in nearly all infected patients. Cytotoxic factors elaborated by H.p. as well as autoimmune cell damage from the abundant inflammatory response contribute to gastric epithelial cell injury. Antrum gastritis increases gastrin release. The impact of H.p.-infection on gastric acid physiology is complex and usually results in increased gastric acid secretion in duodenal ulcer patients and diminished acid output in patients with gastric cancer. Multiple clinical outcomes including asymptomatic gastritis, duodenal ulcer, gastric ulcer, gastric carcinoma and gastric MALT lymphoma are associated with H.p.-infection. Differences in disease manifestation seem to result from a complex interaction of bacterial virulence, host factors as well as environmental factors. The acid-secretory ability of the infected individual seems to be the main variable determining outcome: Patients with high acid production typically develop antrum-predominant gastritis and are at an increased risk for duodenal ulcer. In contrast patients with low gastric acid secretion frequently develop pangastritis, which may progress to chronic atrophic gastritis and carcinoma.     

Electroacupuncture improves restraint stress-induced delay of gastric emptying via central glutaminergic pathways in conscious rats

Acupuncture has been used for treating functional gastrointestinal (GI) disorders. Animal studies demonstrated that acupuncture improves various stress-induced physiological responses. We investigated the effects of electroacupuncture (EA) at ST-36 (Zusanli; lower limb) on stress-induced delay of gastric emptying. Solid food gastric emptying in 90 min was significantly delayed by restraint stress (27.3 +/- 2.1%, n = 8), compared to that of controls (64 +/- 2.1%, n = 8). Restraint stress-induced delay of gastric emptying was significantly restored by the intracisternal (IC)-injection of GABA(A) receptor antagonist, bicuculline methiodide (46.5 +/- 3.1%; n = 6) and GABA(B) receptor antagonist, phaclofen (48 +/- 3.3%; n = 6). Delayed gastric emptying induced by restraint stress was significantly improved by EA at ST-36 (49.7 +/- 1.4%). The stimulatory effect of EA on stress-induced delay of gastric emptying was prevented by pretreatment with IC-injection of glutamate receptor antagonist, kynurenic acid (30.1 +/- 2.1%). In conclusion, restraint stress-induced delay of gastric emptying is mediated via central GABA(A) and GABA(B) receptors. EA at ST-36 stimulates glutaminergic neurons in the brainstem resulting in improvement of stress-induced delay of gastric emptying.
