Gastric emptying rates in idiopathic dyspepsia with and without hunger pain

It has been previously observed that in dyspeptic patients with hunger pain, that is, with pain suggestive of the presence of peptic ulcer, only 12% had an endoscopically demonstrated ulcer, the remaining 88% showing absence of important macroscopically detectable lesions (idiopathic dyspepsia). In order to investigate the possibility of a relationship between hunger pain and some alteration in gastroduodenal motility, the gastric emptying rates of patients presenting idiopathic dyspepsia with and without hunger pain were compared with those of normal control subjects. The study was conducted in 40 patients presenting idiopathic dyspepsia, 20 with and 20 without hunger pain, and 30 voluntary apparently normal control subjects. The patients and the controls ingested, with a standard breakfast, a gelatine capsule containing 10 radioopaque polyurethane markers, and the gastric emptying of the markers was evaluated taking 3 x-ray films of the abdomen at 1.5, 3.0 and 4.5 hours after the breakfast. The gastric emptying rates of the markers were significantly higher in the patients with hunger pain, and significantly lower in the patients without hunger pain, than in the normal control subjects. In idiopathic dyspepsia with and without hunger pain there are, respectively, abnormally increased and abnormally decreased gastric emptying rates of undigestible solid markers. Our findings could help to better understand the pathogenesis of those different types of dyspepsia and, consequently, to improve their treatment.

Gastric emptying rates in idiopathic dyspepsia with and without "hunger pain".

It has been previously observed that in dyspeptic patients with "hunger pain", that is, with pain suggestive of the presence of peptic ulcer, only 12% had an endoscopically demonstrated ulcer, the remaining 88% showing absence of important macroscopically detectable lesions (idiopathic dyspepsia). In order to investigate the possibility of a relationship between "hunger pain" and some alteration in gastroduodenal motility, the gastric emptying rates of patients presenting idiopathic dyspepsia with and without "hunger pain" were compared with those of normal control subjects. The study was conducted in 40 patients presenting idiopathic dyspepsia, 20 with and 20 without "hunger pain", and 30 voluntary apparently normal control subjects. The patients and the controls ingested, with a standard breakfast, a gelatine capsule containing 10 radioopaque polyurethane markers, and the gastric emptying of the markers was evaluated taking 3 x-ray films of the abdomen at 1.5, 3.0 and 4.5 hours after the breakfast.

A new questionnaire for the diagnosis of dyspepsia.

A questionnaire to diagnose dyspepsia was created. The questionnaire consists in 9 items written in very clear and understandable language and related to the cardinal symptoms of dyspepsia (easy sensation of fullness, postprandial epigastric fullness, heartburn, regurgitation, nausea, vomiting, postprandial epigastric pain, excessive belching and hunger pain). The questionnaire also includes a system of quantification levels for each symptom, taking into account its frequency and intensity of presentation in the previous two weeks: 1 point, if the symptom did not bother at all or only infrequently; 2 points, if it bothered only a little; 3 points, if it bothered moderately; and 4 points, if it bothered a lot. The questionnaire was applied to 40 patients with dyspepsia and 20 healthy control subjects, and their answers were compared with data obtained by anamnesis. For the comparison, three criteria were considered to define, with the questionnaire, the existence of dyspepsia: A) Presence of a minimum of 2 symptoms, and at least one of them with a quantification level of 2 points or more; B) Presence of a minimum of 2 symptoms, and at least one of them with a quantification level of 3 points or more; and C) Presence of a minimum of 2 symptoms with a quantification level of 3 points or more. Of these three criteria, criterion B was found to be the best, and following it, the sensitivity and specificity of the questionnaire were, respectively, 95% and 100%. The new questionnaire will be, for sure, a useful instrument to accurately investigate dyspepsia, specially in large population groups.

[Microscopic colitis in patients with chronic diarrhea]. / Colitis microscópica en pacientes con diarrea crónica

It has recently been suggested that there is an association between infectious gastroenteritis and irritable bowel syndrome with chronic diarrhea; and a striking similarity between the microscopic lesion observed in this condition and the lesion described in microscopic colitis (MC). As in developed countries MC is found in only 12.6 to 15% of patients with chronic diarrhea, we thought it worthwhile to investigate in Perú, a developing country with high prevalence of infectious gastroenteritis, the prevalence of MC also in patients with chronic diarrhea. One hundred and ten patients with chronic diarrhea underwent biopsies from the right and left colon, and the biopsies were examined histologically to detect MC of lymphocytic or collagenous type.MC was present in 44 (40%) of the 110 patients with chronic diarrhea, being of lymphocytic type in 42, and of collagenous type in. The prevalence of MC observed in Peruvian patients with chronic diarrhea is high when compared to reports from developed countries. This finding supports the idea that infectious gastroenteritis may, under certain conditions, precipitate the appearance of MC, probably by an autoimmune reaction.

[Association between irritable intestinal syndrome and depressive symptoms in a population of high socioeconomical level of Lima]. / Asociación entre síndrome de intestino irritable y síntomas depresivos en una población de nivel socioeconómico alto de Lima.

Irritable Small Bowel (ISB) is the most common disorder in the gastroenterological practice. On the other hand, depression, is also common, and can produce somatic symptoms that could mislead the physician with respect to bowel diseases, particularly of the digestive system. The main objective of this work was to determine the relationship between lower digestive tract symptoms and symptoms of depression in a population of high socio-economic status in five districts of Lima. A cross-sectional study on the prevalence of lower digestive tract symptoms and symptoms of depression was carried out, together with a case-control study to evaluate the relationship between lower digestive tract symptoms and symptoms of depression. It included 300 individuals. The Beck Inventory for Depression and the Manning Criteria for ISB were used. Significant association (p<0.05) between lower digestive tract symptoms and symptoms of mild depression was found, with a OR=10.9 and significant statistical association between symptoms of moderate depression and lower digestive tract symptoms (p=0.01 and OR=3.48). It is concluded that there is a connection between lower digestive tract symptoms and symptoms of depression, in a population of high socio-economic status in five districts of Lima.

Geographic factors probably modulating alternative pathways in Helicobacter pylori-associated gastroduodenal pathology: a hypothesis.

It is hypothesized that probable geographic factors of nutritional type, nonrelated to development or socioeconomic level, may modulate the conversion of Helicobacter pylori-associated active chronic gastritis from its early stages to chronic atrophic gastritis (CAG). The factors could be diets low in antioxidant vitamins and other micronutrients such as selenium. In regions of the world where these modulating factors are not present, active chronic gastritis tends to stay in its early stages and to predispose individuals to duodenal ulcer. On the contrary, in regions where the modulating factors are present, the frequency of CAG increases markedly. When CAG becomes severe and extensive, hypochlorhydria ensues. Hypochlorhydria decreases the predisposition to duodenal ulcer, while CAG, a precancerous lesion, predisposes individuals to gastric cancer of the intestinal type. The hypothesis could be tested in a multicenter, multiregional study to (1) determine endoscopically and histologically the prevalence rates of duodenal ulcer, gastric ulcer, gastric cancer, and H. pylori-associated CAG in large series of dyspeptic patients and (2) correlate these prevalence rates with blood levels of micronutrients in these patients.
