Among 125 consecutive transplant recipients 10 (8%) demonstrated previous or present peptic ulcer and 9 underwent prophylactic gastric resection before transplantation. Two of these patients experienced upper GI complications in the posttransplant period and 1 died. Another 7 patients without previous dyspepsia had similar problem after transplantation and 4 died. Prophylactic gastric resection is recommended in potential recipients with pretransplant ulcer disease.

The effect of a pepsin-inhibiting pentapeptide, pepstatin, upon the peptic activity and gastric acidity was investigated in 9 men with ulcer dyspepsia and a high acid output. Subtotal inhibition of peptic activity was obtained, basally as well as after broth stimulation, as early as 15 minutes after the method of administration, and the inhibition remained almost unchanged during the 60 minutes of the experimental period. The acidity was not affected by pepstatin. No side-effects occurred. The results confirm preliminary reports on the pepsin-inhibitory activity of the drug. It is concluded that pepstatin ought to be investigated with regard to its clinical effect upon peptic ulcer.

A patient with dyspepsia and multiple gastric polyps associated with generalized neurofibromatosis is described, and the English literature on generalized neurofibromatosis with gastric involvement is reviewed. Nine patients with gastric neurofibromas have been reported and 2 with one and two gastric polyps respectively, but none with multiple gastric polyps. The commonest presentation has been dyspepsia suggestive of a peptic ulcer.

In a retrospective study of 195 patients with a perforated peptic ulcer 18 per cent of the patients had taken aspirin, phenylbutazone or corticosteroids during the period before the perforation. In a controlled prospective trial, 18 of 22 patients (82 per cent) had taken drugs known to be potentially harmful to the stomach. Aspirin was the drug mainly used. Thirteen of 22 patients had taken the drugs within 12 hours of the perforation, usually because of symptoms not related to the gastro-intestinal tract. Drug consumption and perforation of pre-pyloric ulcers were most closely associated; the latter applies particularly to female patients, who either had only a short history of upper gastro-intestinal dyspepsia or were asymptomatic.

Esophageal, fundal, antral, and duodenal mucosal biopsies from 10 patients with heartburn were compared with biopsies from 18 patients with dyspepsia but without heartburn or radiographic or endoscopic evidence of peptic ulcer disease, gastric retention, or esophageal stricture. There was a highly significnt correlation between heartburn and antral gastritis and duodentitis (P less than 0.01). It is suggested that histologic reflux changes are determined by the severity of reflux and reparative potential of the esophageal mucosa. Heartburn, on the other hand, is more related to the nature of the refluxed fluid. The fluid most likely to induce heartburn is one containing duodenal fluid, which is also believed to be an important cause of antral gastritis.

Dyspepsia may result from over-indulgence in alcohol and food, or from anxiety and emotional problems. It may also indicate a peptic ulcer, oesophagitis or less commonly, gallstones or gastric cancer. Investigation by endoscopy or barium studies is always indicated when an organic lesion is suspected. Reassurance, tranquillizers and antispasmodics help patients with functional dyspepsia. Antacids given hourly between meals are important in the treatment of all symptomatic peptic ulcers. Cimetidine causes rapid symptomatic relief of duodenal ulcer symptoms, and most ulcers will heal with six weeks' therapy. Gastric ulcer can be treated with carbenoxolone, but this drug is avoided in the elderly and in patients with cardiac failure or hypertension. Anticholinergic drugs are of value in duodenal ulcer, especially for night pain, but they should not be used in patients over the age of 50. Special diets are of no value. For the heartburn of oesophagitis, weight reduction and a regime of regular antacid therapy remain the important measures.

One-hundred and one patients admitted to hospital with acute upper gastrointestinal haemorrhage whose initial barium-meal X-ray examination revealed no abnormality have been followed up 5 to 14 years later. Forty-five were symptom-free, and 8 had dyspepsia, but the barium-meal X-ray findings were still normal. Disease of the lower oesophagus, the stomach or the duodenum was found in 20, 16 of whom had a chronic peptic ulcer and two had gastric carcinoma. There was a poor prognosis for those gastric-ulcer patients whose diagnosis had been missed initially.

A series of 349 survivors of perforated peptic ulcer was followed for periods of up to 23 years. Almost nine out of every 10 patients suffered from dyspepsia during follow-up. Subsequent elective gastroduodenal surgery was required in more than a quarter of the cases. The surgery rate for gastric ulcer was more than one and a half times that for pyloroduodenal ulcer, and for females almost double that for males. The highest rate of all was for females with gastric ulcer, of whom almost one half came for surgery. One in five patients bled during follow-up. One in eight developed stenosis of the stomach of duodenum, and one in 11 perforated again. There was a significantly increased incidence of subsequent perforation and stenosis in those with an initial perforation of 5 mm or more in diameter. Gastric carcinoma occurred in less than 2% of cases and was restricted to cases of pyloroduodenal perforation. When complications occurred, the majority did so within five years. Only 15% of the 262 patients about whom complete information was available had no complications on follow-up. The indications for definitive surgery at perforation should be extended to include perforated gastric ulcer in the female, particularly if the ulcer is large.

Evidence is accumulating that Helicobacter pylori infection plays a major contributory role in peptic ulcer disease [Duodenal Ulcer (DU) and Gastric ulcer (GU)] and non-ulcer dyspepsia (NUD). We, therefore, studied prospectively 210 consecutive patients with upper gastrointestinal symptoms (62 DU, 38 GU and 110 NUD) to determine the prevalence of H. pylori infection and to investigate their association with histological gastritis. Using endoscopic biopsy of the gastric antrum for diagnosing H. pylori infection by Campylobacter-like Organism (CLO) test, histology or bacteriology, the overall prevalence of H. pylori was 63.3 per cent. When H. pylori infection was related to diagnosis, DU had the highest prevalence rate of H. pylori infection (66%), GU and NUD were less frequently associated with H. pylori infection (55% and 44% respectively). We found a close association between H. pylori infection and histologically antral gastritis, in that 72.7, 61.7, and 62.6 per cent of the DU, GU and NUD patients with antral gastritis (respectively) had H. pylori infection. In contrast, none of these patients seen with normal antrum had H. pylori infection. We also found that the prevalence of H. pylori in our patient series was not age related. Of the three procedures used to demonstrate H. pylori, the CLO test and histological staining method gave the highest yields of 84.9 and 79.6 per cent respectively, and bacteriology in only 44.3 per cent, we conclude that the prevalence of H. pylori infection in Thai patients with upper gastrointestinal symptoms is high. H. pylori infection commonly occurs in the patients with antral gastritis, suggesting a possible etiologic role for the bacterium in the histologic lesion.

The prevalence and the serum levels of IgG antibody to Herpes simplex virus type 1 or 2 (HSV1, HSV2) and to cytomegalovirus (CMV) were studied by ELISA in patients with active peptic ulcer -- duodenal and gastric -- and non-ulcer dyspepsia. Two hundred and forty-two consecutive patients with endoscopically confirmed active peptide ulcer -- 170 duodenal ulcers, 72 gastric ulcers -- and 95 consecutive patients who fulfilled the criteria for the diagnosis of non-ulcer dyspepsia were included in the study. The patients, aged 17-80 years, were well matched for age and sex. Antibody to cytomegalovirus was found in 83% of duodenal ulcer, 85% of gastric ulcer and 75% of non-ulcer dyspepsia patients; differences were not significant. The prevalence of HSV1 antibody was significantly higher in patients with duodenal ulcer than in those with non-ulcer dyspepsia (p < 0.025); the prevalence of HSV2 antibody was significantly higher in patients with duodenal or gastric ulcer, than in those with non-ulcer dyspepsia (p < 0.05, p < 0.01, respectively); however, antibody levels (mean optical density) to the viruses studied were similar for all groups of patients. These results provide some evidence that HSV might be implicated in the pathogenesis of peptic ulcer disease.
