An unselected group of 33 renal transplant recipients were examined by upper gastrointestinal endoscopy at between two and four months after transplantation. All abnormal lesions were documented and biopsied and, in addition, random biopsies were obtained from the gastric antrum and from the first part of the duodenum. The biopsies were examined and graded for gastritis and
duodenitis
and the presence of Helicobacter pylori was noted.
Duodenitis
was identified in 16 patients and gastritis in 10; four patients had a
gastric ulcer
. Helicobacter was identified in the gastric antrum of 16 patients (48%) and was strongly associated with symptomatic dyspepsia, with gastritis, and with peptic ulceration. There was no relationship between H pylori and prednisolone dose, serum cyclosporine levels, or renal function. H pylori was found to be common in the upper GI tract of renal transplant recipients and may explain the high prevalence of upper GI pathology in these patients. It is interesting to speculate that immunosuppression may contribute to this, although there is no direct evidence from this study to support this theory.

The hypothesis that non-secretors of ABO blood group antigens, a group shown to be more susceptible to certain bacterial infections, may be at greater risk of gastroduodenal disease because of increased susceptibility to Helicobacter pylori infection was investigated. Of 101 patients with symptoms of dyspepsia who were undergoing endoscopy, 32% were non-secretors (determined from Lewis blood group phenotype), 36% had endoscopically visible gastroduodenal disease (antral gastritis,
gastric ulcer
, erosive
duodenitis
, duodenal ulcer or some combination), and 58% had H pylori detected in antral biopsy specimens. Non-secretors and patients with H pylori infection were significantly more likely to have gastroduodenal disease (p = 0.02 and p = 0.002 respectively). There was, however, no significant association between secretor status and H pylori infection, logistic regression analysis confirming that these were independently associated with gastroduodenal disease. Overall, the relative risk of gastroduodenal disease for non-secretors compared with secretors was 1.9 (95% confidence intervals 1.2, 3.2). Non-secretion of ABO blood group antigens is not related to H pylori infection but is independently and significantly associated with endoscopic gastroduodenal disease. The mechanism of this remains to be explained.

The author conducted a study of personality characteristics using Ko's mental health questionnaire (KMHQ) on 279 patients who received upper gastrointestinal endoscopic examination at the Taichung Veterans General Hospital during the three months from May 12 to August 11, 1983. Those patients, 203 men and 76 women, voluntarily entered the study. Forty-four patients were randomly selected to receive the same KMHQ again 18-21 months later. The 13 subscales of the KMHQ were confirmed to have a good value of the test-retest reliability (r = 0.419 to 0.796, p < 0.001). Based on the findings of endoscopic examination, 279 patients were divided into two groups: the experimental group of 104 patients (those with
gastric ulcer
, duodenal ulcer and mixed abnormal findings) and the control group of 175 patients (those with normal findings, superficial gastritis and
duodenitis
). A comparison of the 13 subscales of the KMHQ between these two groups of patients revealed no significant differences in the mean scores except that a greater obsessionality index (scale VII) was seen in the experimental group than in the control group (t = 2.35, p < 0.05). In conclusion, peptic ulcer patients with positive endoscopic findings have the characteristic of significant greater obsessionality according to KMHQ.

The aim of our study was to evaluate the relationship between Helicobacter pylori infection and various gastroduodenal diseases. We also took into consideration alcohol intake and smoking. Two-hundred and fifty-three consecutive patients with ulcer-like symptoms underwent gastroscopic and histological examinations. H. pylori status was evaluated by means of culture, Giemsa stain and CP-test, upon obtaining bioptic samples of gastric mucosa. Two hundred eighteen patients were affected by gastritis, 171 of which were H. pylori positive (78.4%); of 164 patients with active gastritis, 158 were H. pylori positive (96.3%). In 63 patients with duodenal ulcer, H. pylori was present in 58 cases (92.1%). Of 14 patients with
gastric ulcer
, 11 were H. pylori positive (78.6%). Out of 133 patients with
duodenitis
associated with active ulcer or a history of previous ulcer, H. pylori was found in 112 patients (84.2%). Among the 27 patients with "autonomous"
duodenitis
, 18 were H. pylori positive (66.6%); the comparison between the two groups of patients with
duodenitis
concerning H. pylori infection was statistically significant (p = 0.033). Of the 119 patients tested for acquired MALT, 39 were found positive (32.7%); among these 34 patients were H. pylori positive (87.1%) and only 5 patients were H. pylori negative (12.9%). Thus our study confirms the importance of H. pylori in gastroduodenal pathology underlining its role in the development of acquired MALT (mucosa associated lymphoid tissue) for its possible evolution in low grade B cell primary gastric lymphoma. Alcohol intake and smoking do not appear to play a role in H. pylori infection.

A retrospective study of 200 endoscopies performed on 168 children (90 girls and 78 boys) aged 3 months to 18 years (median 6 years) is reported. All procedures were completed successfully in an adult endoscopy unit in a comprehensive health centre. Most children of less than 6 months and above 12 years of age needed no intravenous sedation. One child developed respiratory depression and was successfully resuscitated. Indications for endoscopy were: small intestinal biopsy, 78 (46%); recurrent abdominal pain, 40 (24%); acute epigastric pain, 13 (8%); persistent vomiting, 12 (7%); haemorrhage, 10 (6%); caustic substance ingestion, six (4%); and dysphagia, four (2%) children. Positive diagnoses were obtained in 123 (62%) procedures. Coeliac disease (26 cases) was the most common histological diagnosis, followed by gastritis (19 cases), oesophagitis (18 cases),
duodenitis
(16 cases), duodenal ulcer (11 cases), hiatus hernia (six cases),
gastric ulcer
(three cases) and oesophageal stricture (two cases). Where specialized paediatric endoscopy units are not feasible, e.g. in developing countries, endoscopic services for children can be safely provided by paediatric endoscopists as part of an adult endoscopy service, provided that suitable resuscitation equipment is available and the necessary modifications to meet the medical and psychological needs of children and their parents are taken into consideration.

Gastric and duodenal biopsies from 90 patients with various acid peptic disorders-reflux esophagitis (n = 24),
gastric ulcer
(n = 13), duodenal ulcer (n = 47) and nonulcer dyspepsia (n = 6)-were examined. Seven patients with minimal dyspeptic symptoms and an endoscopically and histologically normal stomach and duodenum served as controls. Immunoperoxidase staining for gastrin-producing G cells, somatostatin-producing D cells and serotonin-producing EC cells was carried out on fundic, antral and duodenal biopsies, and was quantified using a Zeiss MOP Videoplan using the peroxidase-antiperoxidase technique of Sternberger. In the gastric antrum, a G:D:EC cell ratio of approximately 1.6:1:1-was observed. In the duodenum the corresponding ratio was 1:1:2.4. No significant differences were observed within any of the major diagnostic categories. Patient age, sex, duration of symptoms, smoking habits, alcohol consumption and nonsteroidal anti-inflammatory drug use had no effect on endocrine cell densities. Reduced G cell density in the descending duodenum was observed in the presence of mild
duodenitis
in four patients. In four patients with evidence of antral intestinal metaplastic changes, a significant increase in duodenal G cell densities was found. These results suggest that a change in the number of G, D or EC cells does not play a primary role in the pathophysiology of acid peptic disorders in the majority of patients.

This study aimed to assess the prevalence of endoscopic and histological gastroduodenitis as well as helicobacter-like organisms in patients with peptic ulcer. After diagnostic endoscopy, gastroduodenal biopsy specimens were taken from thirty patients (n = 30) with clinical and endoscopic diagnosis of peptic ulcer (duodenal ulcer = 25,
gastric ulcer
= 5). Endoscopic gastroduodenitis occurred in 18 patients (60%). Histological gastritis was detected in the gastric body or antrum in 25 (83%) and
duodenitis
in 17 (57%) patients. There was significant correlation between endoscopic and histological gastritis (p < 0.05). Helicobacter-like organisms occurred in 73% of the patients with peptic ulcer and in 88% of the antral biopsy specimens showing antral gastritis. Presence of helicobacter-like organisms was in particular associated with acute on chronic gastritis compared to chronic gastritis (p < 0.01). Moreover the patients with gastritis were found to belong to the older age group and 81.8% had blood group O +ve (p < 0.01 and p < 0.05 respectively). We conclude that presence of helicobacter-like organisms in patients with peptic ulcer is significantly associated with acute on chronic gastritis.

Given that chagasic patients in the indeterminate form of this disease, can have abnormal motility of the digestive tract and immunologic abnormalities, we decided to assess the frequency of peptic disease and Helicobacter pylori (Hp) infection in these individuals. Twenty-one individuals, 13 males and 8 females, mean age 37.6 +/- 11.1 years, were examined. Biopsies of the duodenum, antrum, lesser and greater gastric curvature and esophagus were performed. The endoscopic findings were of chronic gastritis in 20 (95.2%) patients, duodenal ulcer in 3 (14.3%), gastric and duodenal ulcer in 3 (14.3%),
gastric ulcer
alone in 1 (4.8%), esophagitis in 5 (23.8%), and
duodenitis
in 5 (23.8%). The diagnosis of infection by the Hp was done by the urease test and histologic examination. Hp infection was found in 20 (95.2%) individuals: in 20 out of them in the antrum, in 17 in the lesser curvature, and in 17 in the greater curvature. Hp was not found in the esophagus and duodenum. The only individual with no evidence of infection by Hp was also the only one with normal endoscopic and histologic examinations. The histologic examinations confirmed the diagnoses of
gastric ulcer
as peptic, chronic gastritis in 20 patients,
duodenitis
in 14, and esophagitis in 9. In this series the patients had a high frequency of peptic disease, which was closely associated with Hp infection.

The important long-term outcomes after Helicobacter pylori eradication are the proportion of patients with continuing symptoms, and the rate of recrudescence of the infection. Patients with proven H. pylori infection prior to treatment and a negative urea breath test at least 4 weeks after completing treatment were invited to return for a further urea breath test and a questionnaire. There were 167 patients and the mean interval since the post-treatment urea breath test was 16 months. The endoscopic diagnoses were duodenal ulcer 72,
duodenitis
17,
gastric ulcer
26, normal or oesophagitis 52. The ethnic groups were European 86, Maori 25, Pacific Island 28 and other ethnic groups 28. Ten patients (6%) had a positive urea breath test at follow up. The proportion of patients showing recrudescence of H. pylori was related to the delta value (delta) of the post-treatment urea breath test: delta 0-2, five of 146 (3.4%); delta 2-3, two of 18 (11%); and delta 3-4, three of five (60%). A symptom questionnaire was given to 147/157 patients with a persistently negative breath test; 60 had no symptoms, 31 had heartburn, 30 had epigastric pain, 15 had both heartburn and epigastric pain, and 11 had nausea or other symptoms. There were fewer symptoms in patients with
gastric ulcer
(GU) compared with patients with duodenal ulcer (DU) and non-ulcer patients. Twenty-four patients (16%) were taking H2-antagonists (including seven DU and five GU), 15 were taking antacids and four were taking omeprazole. There was no difference in medication use between diagnostic groups. Eighteen of the 46 patients (39%) with heartburn stated that this was a new symptom. Heartburn was a common symptom for duodenal ulcer patients after eradication (24/74, 32%). A second urea breath test 6-12 months after eradication is required to definitely prove eradication. Patients with a breath test delta value of 2-4 should have a repeat urea breath test.

To determine the clinical significance of Helicobacter pylori seropositivity and seronegativity in healthy blood donors, we carried out a serological evaluation of Helicobacter pylori status and endoscopy in a healthy blood donors population. In all, 1010 donors were screened for Helicobacter pylori by IgG ELISA and assessed for pepsinogen I and gastrin levels by RIA; 298 IgG seropositive and 61 seronegative subjects underwent endoscopy with biopsies. Of 359, 165 were also tested for CagA by western blotting. Of the 298 IgG seropositives, 274 were shown to be infected on biopsy testing. Endoscopy revealed 70 peptic ulcers, 41 cases of erosive
duodenitis
, and two gastric cancers. In all 105 seropositive donors were tested for CagA and 69 were CagA positive [34/58 gastritis (58.6%), 24/35 duodenal ulcer (68.6%) and 11/12
gastric ulcer
(91.6%)]. Histologically active/chronic gastritis was associated with CagA: 88.4% vs 50% (CagA seropositive vs seronegative). Of the 61 IgG seronegatives, 59 were negative on biopsy testing. At endoscopy three had
duodenitis
. Of the 60/61 IgG seronegatives tested for CagA, one had a moderate reaction. Duodenal ulcer donors showed higher pepsinogen I levels than donors without duodenal ulcers (97.7 microg/ml vs 80.9 microg/ml respectively). Screening for Helicobacter pylori and anti-CagA seropositivity and pepsinogen I can identify individuals likely to have gastroduodenal pathology even in the absence of symptoms.
