Gastrointestinal symptoms are common in acute falciparum malaria. Dyspepsia often occurs in such patients and sometimes it is exceptionally severe. However, the pathogenesis of the dyspeptic symptoms in malaria has not been clearly defined. Upper gastrointestinal endoscopy was performed in 40 patients with acute falciparum malaria in order to correlate the dyspeptic symptoms with the macroscopic (endoscopic) and microscopic (histologic) pathology of stomach and duodenum. The patients were divided into a dyspeptic group (n = 20, male/female ratio = 17/3, age range 18-50 years, mean age = 28.85 + 9.14 years), and a non-dyspeptic group (n = 20, male/female ratio = 16/4, age range 15-47, mean age 26.05 + 9.98 years). The findings revealed that dyspepsia correlated with topographic endoscopic pangastritis (p = 0.0014), the category of endoscopic antral gastritis (p = 0.013), and the histologic severity of antral gastritis (p = 0.0434). The results suggested that gastritis should be considered in acute falciparum malaria patients presenting with dyspepsia.

One hundred and sixty ex-servicemen who had been prisoners of war in south-east Asia during 1942-5 were investigated for infection with Strongyloides stercoralis. Larvae were found in 44 (27.5%) of the men, who had therefore been infected for 34-37 years. Direct microscopy of the faeces was the most successful diagnostic method, giving a positive result in 37 cases (84%); multiple examinations were often necessary. Faecal culture was positive in 30 cases (68%), but examination of duodenal fluid obtained with the string test gave a positive result in only 17 (39%). The mean blood eosinophil count and mean serum IgE concentration were higher in the infected men, though normal values were often found in individual cases. Clinical manifestations of isolated strongyloides infection were analysed by comparing the infected men with control groups of ex-prisoners in south-east Asia without proved strongyloidiasis and ex-prisoners in Europe. Twenty-nine infected men (66%) complained of non-specific urticaria, and 13 (30%) had pathognomonic larva currens. Gastrointestinal symptoms significantly more common in the infected group were diarrhoea, indigestion, lower abdominal pain, pruritus ani, and weight loss (p <0.05-p <0.0005).The study group was thought to be reasonably representative of Allied ex-servicemen imprisoned in south-east Asia during the second world war. Probably there are many thousands of infected persons in several countries. The worm has an unusual ability to multiply, and larvae may spread throughout the body in immunosuppressed subjects.

Unripe Banana (Plantain) is used in South India as a bland diet for peptic ulcer patients. Flour made of plantain is quite often prescribed in dyspepsia in this part of the country. This has led to the belief that ripe banana may also be a bland fruit. However, it was observed by the Senior Author that ripe banana does produce symptoms of hyperacidity. Hence a study was undertaken to assess whether ripe banana is a bland food or not. A total of 115 patients entered the study. 89 individuals had no GIT symptoms, 15 patients had proved peptic ulcer while 11 patients had non-ulcer acid dyspepsia. The gastric residue was emptied by a nasogastric tube after a night fast. Patients were then given 80 gms. of banana or porridge on two different days. Then consecutive 15 minute samples of gastric juice were collected and submitted for estimation of acid output in mEq/l. It was observed that gastric acid values were higher following banana as compared to porridge and the difference was statistically significant (p < 0.001). It was was thus concluded that ripe banana is not a bland food. It should not be recommended as a part of bland diet for patients of acid peptic disease.

A study of the abdominal/gastrointestinal symptom panorama in relation to socio-economic factors and health care consumption in the general population was performed in Osthammar, Sweden. A postal questionnaire was sent to a representative sample of the adult population (n = 1260). The response rate was 87%. The responders with symptoms (52.1%) subjectively rated their illness on visual analogue scales. All responders were classified as asymptomatic or having 'minor' or 'major' abdominal symptoms. Those having dyspepsia, reflux or irritable bowel syndrome were also ranked as 'minors' or 'majors'. The proportion of subjects with abdominal/gastrointestinal complaints decreased with age, mainly due to a decrease of 'major' symptoms. Also, the proportion of complainers increased among the more educated. Those on sick leave and students had more and worse symptoms than the others, despite the former seldom stating abdominal discomfort as the main reason for sick listing. Fifty-five per cent of all persons reporting abdominal/gastrointestinal symptoms had at some time consulted a doctor because of such complaints, the proportion increasing with severity, as did drug consumption and the rate of previous abdominal operations, with appendectomy as an exception. The results show that it is possible to rank the illness along a severity dimension among persons with abdominal/gastrointestinal complaints in epidemiological research.

Most trials of non-ulcer dyspepsia (NUD) and Helicobacter pylori associated gastritis (HPAG) have not used validated methods of measuring symptoms. Three attributes are necessary for use of symptom severity scoring systems as outcome measures in clinical trials: reproducibility, responsiveness to change and validity compared to corroborating measures. The objective of this study was to establish that selected gastrointestinal symptoms recorded as a series of 5-point Likert Scales meet the 3 criteria for use as outcome measures in clinical trials. Patients with NUD (Helicobacter pylori-negative) and HPAG were studied. A preliminary assessment of 24 patients was used to select the 8 most frequently occurring and most severe symptoms. These symptoms were then scored in a further 55 patients to assess their utility as outcome measures. Observations were made at 3 time points, enrollment (T1), after 1 week with no intervention (T2) and after 4 weeks of therapy for either disease (T3). The study took place in a university hospital outpatient gastroenterology service. Symptom scores were reproducible before treatment (symptom scores at T1 and T2 were correlated), responsive (symptom scores changed after treatment between T2 and T3) and valid (symptom score changes corresponded to changes in general health status). Scoring of gastrointestinal symptom severity using 5-point Likert Scales satisfies the 3 criteria for use as outcome measures in clinical trials of NUD and HPAG.

This study aimed to determine the prevalence of dyspeptic symptoms and premalignant gastric lesions in coal miners and sex matched population control subjects. Retired coal miners and men from the general population in north Nottinghamshire were sent a dyspepsia questionnaire to fill in, and those with upper gastrointestinal symptoms were invited for gastroscopy and biopsy. A total of 1272 men from the general population and 2099 retired coal miners aged 50-75 years took part in the study. Some 977 of 1272 (76.8%) control subjects and 1715 of 2099 (81.7%) miners replied to the questionnaire. A total of 308 of 977 (31.5%) controls and 620 of 1715 (36.2%) miners were positive for at least one symptom. There was a highly significant difference between the numbers of surface mine and underground workers who reported dyspeptic symptoms (66 of 300 (22%) v 425 of 1083 (32.2%) of p < 0.0001). Histology showed that significantly more miners than controls had acute on chronic gastritis (22 v 11%; p = 0.01) and intestinal metaplasia (23 v 8%; p = < 0.0001). Coal miners may be a suitable group for gastric premalignancy screening using an upper gastrointestinal symptom questionnaire and upper gastrointestinal endoscopy.

In recent years, there has been increasing interest in how gastrointestinal symptoms relate to and impact on patients' health-related quality of life. This is particularly the case for functional gastrointestinal disorders that are characterized by a lack of biological markers for disease activity. There is only a slight variation in the type of gastrointestinal symptoms reported with different gastrointestinal disorders, and patients with dyspepsia or irritable bowel syndrome, for example, often describe a variety of gastrointestinal symptoms with considerable overlap between them. The same pattern has been observed in patients with gastroesophageal reflux disease, even though heartburn and acid regurgitation are easier to distinguish from other gastrointestinal symptoms, particularly in patients in whom objective reflux is verified. Most aspects of health-related quality of life in patients with gastrointestinal disorders are compromised, irrespective of diagnosis. Patients with functional disorders seem, if anything, to display more emotional distress than those with organic disorders. Given the considerable overlap between different gastrointestinal symptom clusters, it is not surprising that these conditions have a similar impact in terms of perceived health status and quality of life. The key factors associated with the degree of perceived distress and dysfunction relate to disease severity and the presence of abdominal pain symptoms.

Gastrointestinal bleeding and increased intestinal permeability have been observed in marathon runners. We sought to determine if L-arginine would be useful for prevention of these complications. Twenty-three runners were randomized to receive L-arginine (A) or glycine (placebo) (G), 10 grams 3 times daily for 14 days prior to the 1997 Houston-Methodist Marathon. Serum, stool hemoccults and lactulose:mannitol permeabilities were obtained at baseline, immediately after completion of the marathon and approximately 48 hours later. Runners rated their symptoms of nausea and vomiting, belching and indigestion, abdominal pain and bloating, diarrhea, and extremity pain on a 1-5 scale of increasing severity. The L:M was unchanged in either group during the three collections. Occult bleeding occurred in 8%/20% in A and G groups, respectively, p = NS) immediately post-marathon. No runners had occult bleeding 48 hours post-race. Gastrointestinal symptom scores were minimal to nonexistent. Extremity pain scores were similar for groups A and G (2.1+/-1.4 and 2.8+/-1.6, respectively, (p = NS). Fluid intake was similar between both groups (1875+/-1547 vs. 1506+/-970 ml, p = NS). Serum amylase was normal at baseline and remained virtually unchanged. Serum lipase was normal at baseline and immediately post-race in both groups, but increased at 48 hours post-race (82.2+/-34.3 to 121.5+/-53.3 mg/dl [A], p = 0.02 and 114.3+/-55.7 to 181.9+/-162.2 mg/dl [G], p = 0.09). CPK increased significantly and similarly in both groups immediately post-race, and even more dramatically 48 hours post-race (130.3+/-130.8 to 738.8+/-902.9, p = 0.007 to 1966.5+/-3.166.0 mg/dl [A] and 140.9+/-77.9 to 863.0+/-772.3, p = 0.003 to 5619+/-10636.8mg/dl [G]). Modest post-race decreases were seen in most serum amino acids in both groups. Finish times were longer than predicted (23+/-21 and 9+/-7 min for A and G groups, respectively, p = 0.049). Our study failed to show a clear benefit of arginine supplementation for the prevention of intestinal ischemia/reperfusion injury associated with endurance running, but either a detrimental affect on performance with arginine, or enhanced performance with glycine. Skeletal muscle injury was unaffected by arginine or glycine supplementation. The delayed increase in serum lipase suggests mild pancreatic injury, affected by either arginine or glycine supplementation.

Previous studies have shown that patients with chronic alcohol ingestion may show a variety of morphological and functional alterations in the small intestine. In this study, we have focused on the neuroendocrine system in the duodenal mucosa in chronic alcoholics; an area little studied. Twenty-three defined chronic alcoholics admitted to the hospital for detoxification underwent clinical examination, followed by upper gastrointestinal endoscopy and blood tests on average 4 days after the most recent alcohol intake. Biopsy specimens were taken from the distal part of the descending duodenum for both immunohistochemical and routine histological examination. The control group consisted of 25 patients referred for upper endoscopy mainly because of dyspepsia (ulcer, reflux type), but who were otherwise healthy. A normal carbohydrate-deficient transferrin and a history of low alcohol consumption (<40 g/week) were required for inclusion in the control group. The tissue specimens were studied using antisera for the following neuropeptides: cholecystokinin, galanin, gastric inhibitory peptide (GIP), glucagon, motilin, neuropeptide Y, pituitary adenylyl cyclase activating peptide, secretin, serotonin, somatostatin, substance P, vasoactive intestinal polypeptide and protein gene product, as a general marker for neurones and cells of the diffuse neuroendocrine system. The density of nerve fibres was evaluated semi-quantitatively and the number of endocrine cells per unit length of mucosa was counted in sections cut perpendicularly to the mucosal surface. All the different peptidergic nerve fibres in the alcohol group showed higher densities than the corresponding controls. However, this was not a statistically significant difference. A slightly significant increase (P = 0.02) in the numbers of glucagon and GIP cells was seen in the alcohol group. Gastrointestinal symptoms were frequently present (87%) in chronic alcoholics. We suggest that chronic alcohol consumption in man may have a general effect on the peptidergic nerve system and some endocrine cell types in the duodenal mucosa.

Psychologic factors in functional dyspepsia have been discussed in many previous articles. However, the relationship between depression and functional dyspepsia is still obscure. We investigated the impact of depression on clinical symptoms and gastric dysrhythmia in functional dyspepsia. Thirty-nine patients with functional dyspepsia and 18 healthy subjects were included. Patients were investigated with clinical symptoms assessment, Zung's self-rating depression scale, and electrogastrography. Patients with functional dyspepsia were divided into two groups: 21 patients with depression and 18 patients without depression. The depressed patients had similar total gastrointestinal symptom severity scores compared with the nondepressed patients, but with higher total symptom frequency scores (p < 0.05). With regards to symptoms, the depressed patients had higher abdominal fullness severity and frequency scores and nausea frequency scores. The patients with functional dyspepsia had a lower percentage of normal slow wave in both the fasting and fed states and a higher percentage of bradygastria in the fasting state and tachygastria in the postprandial state (p < 0.05). There was no significant difference in the percentage of bradygastria or tachygastria between the depressed and nondepressed patients. There was no correlation between the specific type of electrogastrographic abnormality and the presence or absence of depression in functional dyspepsia patients.
