Non-ulcer dyspepsia, also termed "nervous dyspepsia," is a heterogeneous syndrome: ulcerlike symptoms can occur with the irritable bowel syndrome, gastroesophageal reflux, and other disorders. In addition, there is a significant subgroup of non-ulcer dyspepsia sufferers who have no disorder associated with, and no known cause for, their dyspepsia, and the dyspepsia in this subgroup is given the provisional name of "essential dyspepsia." The aim of this study was to assess if psychological factors are associated with patients who present with essential dyspepsia. Psychometric testing was carried out on 76 essential dyspepsia patients (including 18 patients with gastroduodenitis), 76 randomly selected dyspepsia-free community controls (matched for age, sex, and social class), and 66 duodenal ulcer controls. Essential dyspepsia patients were retested a mean of 3.6 mo later. Using stepwise regression analysis, the initial scores of essential dyspepsia and duodenal ulcer subjects showed them to be more neurotic, anxious, and depressed than community controls; these abnormalities persisted in essential dyspepsia patients on retesting and were not affected by the symptom status. It is concluded that essential dyspepsia patients who present for investigation with symptoms are more likely to be persistently neurotic, anxious, and depressed than dyspepsia-free controls, and this is unrelated to the presence of symptoms, but the association may not be of major clinical significance, as the numerical differences observed between groups were small and the correlation coefficients were low.

Non-ulcer dyspepsia (NUD) is defined as dyspepsia in which investigation shows no evidence of focal gastroduodenal disease or oesophagitis. The aim of the present study was to determine the proportion of NUD patients with other identifiable diseases. We interviewed 327 consecutive patients who had at least 1 month of dyspepsia before a panendoscopy that showed no evidence of oesophagitis, malignancy, or peptic ulcer. Symptoms were assessed by a structured history questionnaire. The existence of gallstones was excluded radiologically. Of the subjects studied, 75 (23%) had irritable bowel syndrome and 71 (22%) gastro-oesophageal reflux, whereas 63 (19%) had both, 25 (8%) had aerophagy, and 14 (4%) had gallstones. Of the remaining 79 patients (24%) 6 had duodenitis and 10 gastritis, whereas 1 had both. Sixty-two subjects (19%) had entirely normal endoscopic results and no ascertainable cause of their dyspepsia (termed provisionally essential dyspepsia). It is concluded that, whereas three-quarters of NUD patients have diseases that fall into other diagnostic categories, nearly one-quarter have essential dyspepsia.

Dietary intakes of two groups of gastrointestinal patients, one group with inflammatory bowel disease (IBD)--Crohn's disease or chronic ulcerative colitis--and the other with functional disorders (FD)--irritable bowel syndrome, nonulcer dyspepsia, or gastroesophageal reflux disease, were assessed by means of 48-hour recalls. The relationships between dietary intake and anthropometric and biochemical measurements were examined. The IBD group had lower mean serum albumin and hemoglobin levels (p less than .05); however, FD patients had less adequate diets. The mean energy intake of women with FD was significantly lower than that of women with IBD (p less than .05) and was associated with inadequate or marginal intakes of many nutrients. Comparison of nutrient intakes between the IBD and FD groups revealed a significantly lower mean intake of folate, ascorbic acid, and vitamin A for women with FD than for women with IBD (p less than .05). In general, women had poorer diets and a higher prevalence of abnormal biochemical parameters than men. One notable feature of the dietary pattern of the women was that they consumed less meat than the general population consumed. Increasing meat consumption would improve the intake of many nutrients, including protein and iron. The results of this study suggest that more attention should be given to the adequacy of dietary intakes of gastrointestinal patients in general and of women in particular.

Since previously reviewed in the Journal (Vol. 12, No. 2), metoclopramide has been confirmed as an effective drug in treating and preventing various types of vomiting and as a useful agent in oesophageal reflux disease, gastroparesis, dyspepsia, and in a variety of functional gastrointestinal disorders. Of considerable importance is the recent evidence of its efficacy when administered intravenously in high dosages in preventing severe vomiting associated with cisplatin. Good results have been achieved in patients not previously treated with cisplatin, but further studies are needed to determine its level of efficacy in patients who have experienced severe vomiting during earlier courses of cytotoxic therapy. Side effects consisting of mild sedation, diarrhoea and reversible extrapyramidal reactions have occurred, but are tolerated by many patients.

The post-fundoplication symptoms were assessed in 226 patients who had symptomatical improvement of gastroesophageal reflux after Nissen fundoplication. Follow-up range was from 3 to 12 years (average 5,6 years). Of these patients, 24% were totally asymptomatic. All had transient postoperative dysphagia which improved within an average of 3-5 months. Forty four per cent had changes in habits of swallowing; 38% had increased abdominal meteorism; 31% were unable to vomit and 19% unable to belch; 12% had pain in the upper left abdominal quadrant; and 10% had dyspepsia. These symptoms were uncomfortable in 26% and disturbing in 10%. Diverse causes can be responsible for these symptoms; mechanical (narrowing of the cardia, postoperative adherences), functional (motor troubles, denervation), and depending of the patients (alimentary habits). The high frequency of post-fundoplication symptoms restrict clearly the success of Nissen fundoplication.

Several studies, using pH monitoring with event markers, have identified patients with normal oesophageal exposure to acid despite an apparent relation between symptoms and reflux episodes. In this series of 771 consecutive patients referred for 24 hour oesophageal pH monitoring, a probability calculation was used to evaluate the relation between symptoms and reflux episodes. Oesophageal exposure to acid was normal in 462 of 771 recordings (59.9%); despite this, 70.8% (327 of 462) of these patients used at least once the event marker. In 96 patients (12.5% of total patients) with normal oesophageal exposure to acid, there was a statistically significant association between symptoms and reflux episodes. The symptom cluster of such patients was similar to that usually seen in patients with gastro-oesophageal reflux disease, but symptoms like belching, bloating, and nausea were common thus overlapping with the symptom pattern of functional dyspepsia. In these patients both the duration and the minimum pH of reflux episodes (either symptom related or asymptomatic) were significantly shorter and higher, respectively, when compared with those of patients with gastro-oesophageal reflux disease. These results are consistent with the idea that oesophageal hypersensitivity to acid is the underlying pathophysiological feature of this syndrome.

Antacids have served us well for over a century. In terms of peptic ulcer disease, the attitude in the late 1950s to 1970s that antacids should be taken only on demand was unjustified and erroneous. 13 recent endoscopic controlled studies have confirmed the efficacy of antacids in the healing of duodenal ulcer, achieving about 75% healing in 4 weeks. The efficacy of antacids in promoting gastric ulcer healing has been less well studied and the results are controversial. The most appropriate and economical antacid regimens for the treatment of duodenal ulcer disease should include tablets or liquid that have acid neutralising capacity of 400 mmol/day given at least an hour after meals. As a long term therapy, antacids appear to work, but need be taken in multiple daily doses, a regimen which is unlikely to meet with long term patient compliance. Patients with gastro-oesophageal reflux disorders or pregnancy-related reflux have also benefited from the usage of antacids ad libitum. Early previous studies have clearly demonstrated the efficacy of antacids in reducing gastro-oesophageal reflux and healing of reflux oesophagitis. The acidity of the gastric contents is the major determining factor in the outcome of the aspiration pneumonitis occurring during delivery. The prophylactic use of antacids during delivery has helped to reduce the severity of this complication. Similarly, the prophylactic administration of antacid aiming to maintain gastric pH between 3.5 to 7.0 has resulted in significant reduction of bleeding due to stress associated ulcers and/or erosive haemorrhagic gastritis in critically ill patients. Antacid therapy, however, is controversial in the management of nonulcer dyspepsia or nonsteroidal anti-inflammatory drug related upper gastrointestinal mucosal damage. Undoubtedly, antacids have major roles to play in the treatment of gastric acid related disorders. They have clear advantages and disadvantages when compared with the antisecretory agents. New proton pump inhibitors in particular have certainly superseded antacids and even the H2-receptor antagonists in many respects. However, the long term safety record of antacids remains unsurpassed by any of the new antisecretory agents.

Dyspepsia is a common, benign condition that may be distinguished from gastroesophageal reflux, irritable bowel syndrome and pancreatobiliary, coronary or musculoskeletal disease by a careful history and physical examination. However, the presence or absence of a peptic ulcer in dyspepsia can be determined only by an endoscopic examination or a barium-contrast radiograph. Although the American College of Physicians has recommended trying drug therapy for patients with dyspepsia before diagnostic tests are done, new data support early diagnosis. Although therapy is initially cheaper than endoscopic examination, over a year the costs even out because most patients with dyspepsia eventually need an endoscopic examination, and many patients with nonulcer dyspepsia are given medication unnecessarily. Endoscopic examination, if available to general practitioners, is the most cost-effective approach to dyspepsia. An approach that does not include endoscopy lacks the opportunity to offer patients convincing reassurance that their illness is not serious, which is arguably the most important treatment in cases of nonulcer dyspepsia. Studies supporting the use of endoscopic examination predate the treatment of peptic ulcers with antibiotics, which makes an initial endoscopic examination to determine whether the patient has an ulcer even more important.

A cytotoxin produced by some Helicobacter pylori strains has recently been identified. The cytotoxin induces intracellular vacuolization of cultured cells. The aim of the present study was to examine the frequency of occurrence of cytotoxin-producing strains of H. pylori from subjects with upper gastrointestinal disease including nonulcer dyspepsia, gastric and duodenal ulcer disease, gastroesophageal reflux disease, and gastric cancer. Broth culture filtrates of clinical isolates of H. pylori recovered from 175 patients were used to inoculate Vero and HeLa cell monolayers for the detection of vacuolating cytotoxin activity. The results obtained demonstrated that the highest percentage of strains producing cytotoxin were found in subjects with peptic ulcer disease (gastric ulcer, 65%; duodenal ulcer, 66%; P < 0.01 compared with nonulcer dyspepsia, 38%). Of the 11 patients with gastroesophageal reflux disease, 4 of 5 patients in this group who had esophageal ulcers, were found to be infected with strains that produced cytotoxin. Three of the four patients with carcinoma of the stomach were also found to be infected with cytotoxic strains of H. pylori. With increasing severity of mucosal damage in subjects with a normal upper gastrointestinal tract, macroscopic gastritis, duodenitis, and peptic ulceration, there were corresponding increase in the proportion of strains producing cytotoxin; these increases were 32, 46, 50, and 66%, respectively. H. pylori strains from subjects with ulcer disease commonly produced vacuolating cytotoxin, suggesting that it may be a virulence factor in the pathogenesis of peptic ulcer disease.

Dyspepsia is a frequent presenting symptom amongst patients attending medical clinics worldwide. However their aetiologies differ geographically. The present study was conducted to identify the aetiologies of dyspepsia of our centre and to determine their clinical characteristics. Five hundred consecutive patients presenting with dyspepsia were studied at our Institute. All patients underwent detailed structured questionnaire, stool examination, upper gastrointestinal endoscopy, ultrasound scan of upper abdomen and sigmoidoscopy when necessary. Among 500 patients, 34% suffered from essential dyspepsia, 28% had peptic ulcer, 19.2% had cholelithiasis, 10.8% had irritable bowel syndrome and 6% had gastro-oesophageal reflux. Significantly more patients with peptic ulcer experienced night paints, pain relief with food, milk, antacids or H2 receptor antagonists and periodic pain. In patients with essential dyspepsia, pain was continuous, mild to moderate in intensity, aggravated by food or alcohol, without relief with milk, antacids or H2 receptor antagonists and night pains were absent in them.
