Gastric juice from 15 normals, 20 patients with gastric ulcer and 14 patients with erosive haemorrhagic gastroduodenitis was investigated in respect of its activity on unheated and heated fibrin plates and its content of FDP and plasminogen or plasmin with immunochemical methods. Gastric juice from normals showed no activity on unheated and heated fibrin plates, and no FDP or plasminogen could be demonstrated. In the patients with gastric ulcer the gastric juice showed little or no fibrinolytic activity on fibrin plates except in 2, who had regurgitation of duodenal juice and neutral pH of the juice. These patients had equally high activity on heated as on unheated plates and no plasmin could be demonstrated. It was shown that this activity was not due to fibrinolysis, but to non-specific proteolytic activity (probably trypsin). The patients with erosive haemorrhage gastroduodenitis exhibited quite a different picture. The gastric juice from these patients showed extremely high activity on fibrin plates, the activity was higher on unheated than on heated plates. The activity was inhibited in vitro by addition of EACA and in vivo after administration of AMCA. The occurence of plasmic could be demonstrated directly immunologically in the gastric juice. By comparsion of plasmin and trypsin in various assays it could further be improved that the gastric juice in these cases contained plasminogen activator and plasmin. The patients with erosive haemorrhagic gastroduodenitis showed no increase in fibrinolysis in the blood, but low values for plasminogen and alpha2-M, and the serum contained FDP. These findings in the blood and gastric juice were interpreted as signs of local fibrinolysis in the stomach and duodenum. There is reason to assume that this gastric fibrinolysis contributes substantially to the bleeding tendency. The effect of administration of AMCA on fibrinolytic activity and the haemorrhage lends support to the assumption of such a mechanism.

Pirenzepine (PRZ, 75 mg/day for 10 days followed by 50 mg/day for 20 days) was compared with placebo (PL) in the treatment of endoscopically confirmed active gastroduodenitis or duodenal ulcer and with carbenoxolone (CB, 300 mg/day followed by 200 mg/day) in the treatment of gastric ulcer in a 30-day double-blind clinical trial. Ninety-seven of 112 outpatients completed the trial. The results can be summarized as follows: a) Gastroduodenitis. Complete normalization of the endoscopic picture was observed in 61% of the 28 patients on PRZ and in 30% of the 27 on PL. b) Duodenal ulcer. Complete endoscopic healing was observed in 75% of the 12 patients on PRZ and in 44% of the 9 on PL. In both studied PRZ induced improvement in clinical symptoms in more patients than PL. c) Gastric ulcer. PRZ and CB induced complete healing in a similar percentage of patients (64% of 11 and 70% of 10 patients). Better results in dyspepsia were observed in the PRZ group than the CB group. No major side-effects and no pathological changes in blood and urine analyses were observed in PRZ-treated patients.

IgA, IgM and IgC content in blood serum and gastric juice were determined in 89 patients with different gastric and duodenal diseases (57 with duodenal ulcers, 13 with gastric ulcers 8 with chronic atrophic gastritis, 9 with superficial chronic gastritis and gastroduodenitis and two with gastric cancer). Immunoglobulin was established in gastric juice (over 0,3 mg/100 ml) in 49 per cent of all the patients examined with gastric and duodenal diseases. No correlation was found between serum immunoglobulin level and their presence in the gastric juice. No correlation exists between the volume of the basal secretion and the presence or absence of immunoglobulins in the gastric juice. Immunoglobulins were established more often in the gastric juice with lower secretion of hydrochloric acid (in chronic atrophic gastritis and gastric ulcer), while in cases of higher secretion they are more frequently absent. A certain parallelism was established between the changes of hydrochloric acid output and JgA secretion in the gastric juice after stimulation of gastric secretion by Pentagastrin or histamine.

Colloidal bismuth subcitrate (CBS; DeNol) has been studied in clinical trials investigating the treatment of duodenal and gastric ulcer, non-ulcer dyspepsia, duodenitis, non-steroidal anti-inflammatory drug (NSAID)-induced disease, and Helicobacter pylori-induced gastroduodenitis. Healing rates for duodenal ulcer with CBS are significantly better than with placebo and are similar to results obtained with cimetidine or ranitidine. CBS is significantly better in the treatment of duodenal ulcer resistant to standard doses of H2 antagonists than increased doses of H2 antagonists. Duodenal ulcer relapse at 12 months after initial healing with CBS is significantly less than with H2-antagonist therapy. Ulcer healing with CBS is not influenced by smoking. H. pylori eradication with CBS appears to have little effect in ulcer healing but is of major importance in preventing ulcer relapse. CBS is effective in combination with antibiotics in eradicating H. pylori-associated gastritis. In gastric ulcer disease CBS therapy resulted in significant healing advantages over placebo and was comparable to treatment with cimetidine and sucralfate. CBS has been shown to be effective in the treatment of erosive duodenitis. The role of CBS in treatment of non-ulcer dyspepsia and NSAID-induced damage awaits further clinical studies.

As many as 72 patients with erosive and ulcerous injuries to the stomach and duodenum were examined for the clinical efficacy of antepsin (sucralfate). Of these patients, 42 were with duodenal ulcer, 10 with gastric ulcer and 20 with erosive gastroduodenitis). Antepsin exerted a beneficial effect on the painful syndrome and on ulcer and erosion healing. The coefficient of the therapeutic efficacy of antepsin in duodenal ulcer patients turned out to be equal to 2.67 that of gastric ulcer to 2.1 and that in patients with gastroduodenitis was 2.6. The drug did not produce any well-defined side effects. In some cases (8.3%), it caused the appearance or enhancement of constipation. Antepsin is indicated not only in ulcer disease but also in duodenogastric reflux, reflux gastritis and reflux esophagitis.

Changes in the excretion and composition of proteoglycans specific for duodenal ulcer were studied in 50 patients with duodenal ulcer, 30 patients with gastric ulcer, 30 patients with chronic endogenous gastroduodenitis and in 35 healthy persons. In all the examinees proteoglycans were isolated from daily urine, their carbohydrate components--glycosaminoglycans (GAG)--were separated and divided into fractions (keratan sulfate, hyaluronic acid, heparan sulfate, chondroitin sulfate-4, chondroitin sulfate-6, dermatan sulfate, and heparin) by column chromatography on unmodified cellulose. It has been established that only peptic ulcer is characterized by disorders in GAG excretion differing in the period of exacerbation and remission. Changes in the composition of proteoglycans excreted with urine resulted probably from a deficiency of chondroitin sulfate-6 in patients with chronic duodenal ulcer. The deficiency was more marked during exacerbation but did not disappear in the period of remission of duodenal ulcer either.

Diagnostic approaches to the patient with dyspepsia include immediate evaluation with an upper gastrointestinal series, immediate study with esophagogastroduodenoscopy (EGD), or empiric medical treatment, reserving diagnostic evaluation for patients with complications and persistent symptoms after therapy. A literature review of dyspepsia as a symptom, and of duodenal ulcer, gastric ulcer, gastroduodenitis, and gastric cancer summarizes how the diagnostic approaches to the dyspeptic patient affect the precision of diagnostic information, efficacy, patient outcome, and cost. For patients without clinically obvious disease, an approach is developed which reduces cost and retains optimal patient management. The strategy proposes the use of empiric medical therapy while reserving EGD for those few dyspeptic patients who have no or minimal response to therapy after 7 to 10 days, and for the approximately 30% of patients whose symptoms persist, improved, but not resolved after a 6 to 8 week period.

Diagnostic, clinical and therapeutic studies were carried out, under clinical conditions, on 80 patients with endoscopically confirmed chronic erosive gastritis and gastroduodenitis. The subjects aged between 20 and 59 are most often affected, the males being 2 times more often affected. The histological study on the purposeful biopsy of the mucosa of the stomach and duodenum established, most frequently, the presence of chronic superficial gastritis and duodenitis, followed by initial chronic atrophic gastritis. The clinical symptoms were studied in details--pain (91.20%), dyspeptic syndrome (83.7%), hemorrhagic manifestations (hematemesis or melena)--23.7%. In 40% of the patients with erosive gastritis and gastroduodenitis, the disease was combined with duodenal ulcer and in 7.5%--with gastric ulcer. The etiological factors of importance are: food factors, dietetic errors, alcoholic consumption, drug effects (first of all derivatives of Rauwolfia serpentina, followed by the peroral broad spectrum antibiotics, etc), duodenogastric reflux and toxic effect of the bile acids on the antral mucosa. The endoscopic studies are of decisive importance for the diagnosis and determining the effect of the treatment. The treatment with a dietetic regimen, gastro-protective drugs (almagel, preparations of deglycyrrhized licorice--alcid V, vitamin A, spasmolytics) eliminated the erosive alterations in 75% of the patients after 3-week treatment.

A prospective study was carried out in 51 patients admitted for abdominal complaints of at least 1 year's duration. Despite previous hospitalization for the same complaints, no certain diagnosis had been established. After systematic diagnostic procedures in the Medical Dept., Rikshospitalet, 33 patients were given a psychosomatic and 18 patients an organic primary diagnosis. The organic diseases were three cases of Crohn's disease, two of cancer, two of duodenal ulcers, one of gastric ulcer, two of gastroduodenitis, five of postresection syndrome, one of lactose intolerance, one of hyperthyroidism, and one of degeneration of the columna. The patients' condition was registered after 1 year of individual treatment. There was a significant decrease in the number of symptoms, in the psychosomatic score of anxiety, depression, and stress, and in days on sick leave and consultation with physicians in connection with the second compared with the first hospitalization for the whole group, for the psychosomatic group, and for the patients with upper gastrointestinal disease. Increased vitality based on muscular testing was also indicated in the same groups of patients. The study suggests that patients with uncharacteristic abdominal disorders may need a thorough examination at least once in the course of their illness; on the one hand, this may help patients with psychosomatic disease to cope better with their problems, and, on the other hand, primary organic lesions may be difficult to diagnose on the grounds of simple screening procedures.

During a 3-year period, 157 patients with upper gastrointestinal haemorrhage were admitted. In 54 of them gastric blood was made available for study of the level of fibrin-fibrinogen degradation products (FDP) to reveal the prevalence of increased local fibrinolytic activity. In all patients except three, FDP in systemic and gastric blood was identical, at less than or equal to 40 micrograms/ml. Two patients with erosive gastroduodenitis and one with a gastric ulcer had high levels of FDP in blood aspirated from the stomach. The present results would suggest that increased local fibrinolytic activity is very seldom involved in the induction and/or maintenance of upper gastrointestinal haemorrhage.
