[Correlation between immunoglobulin-secreting cells and secretory immunoglobulins in the small intestine in chronic intestinal diseases].

A total of 45 patients were studied: seven with gluten enteropathy and 38 with chronic unspecific enteritis. Histological and immunefluorescent studies were performed and to a part of the cases--enzymatic and electron-microscopic investigations of the jejunal mucosa. An increased number of immuneglobulin -secreting cells was established in the non-treated patients with gluten enteropathy, growing with age. In the cases with chronic unspecific enteritis with a manifested clinic, a tendency to decrease of the number of IgSC was observed, with growing percentage of IgG-SC and the values of the secretory IgG. There was no correlation between the intraepithelially located lymphocytes and those in the chorion, as well as between the duration of the disease, number and percentage distribution of Ig-SC.

[Differentiated diet therapy in chronic intestinal diseases with predominance of the dyskinetic constipations syndrome].

On the ground of clinical observations, studies on the motor-evacuatory functions of the gastro-intestinal tract and its regulation values in dynamics a differentiated dietotherapy and a special complex of exercise therapy have been devised for patients with chronic colites and enterites marked by predominance of constipation. Among basic principles of this dietotherapy were: the content of all nutrients corresponding to physiological standards with the amount of protein increased up to 135 g, creating conditions conducive to sparing of the stomach, pancreas, liver and biligenic organs through exclusion of strong stimulators of the digestive and bile secretion glands, of substrates irritating the liver, regulation of the motor-evacuatory function of the gastro-intestinal tract by a graded increase in the amount of cellular membranes, progressively rising parallel with weakening of the symptoms pointing to irritation of the gastro-intestinal tract organs. The complex set of physical exercises included: those of general tonic and improving the prelum abdominale muscles tonicity, mechanically stimulating the motor function of the stomach and the intestines, periodically changing the intra-abdominal pressure, both upwards and downward.

[Lysozyme in children with acute and chronic inflammatory intestinal diseases].

Fecal lysozyme excretion was determined in two hundred children and adolescent. In sixty three infants with enteritis due to Rotavirus the fecal lysozyme level was found to be significant higher than in the feces of a group of healthy infants (p less than 0.01). Elevated fecal lysozyme excretion could be detected in patients with untreated Crohn's disease. After treatment with Salazosulfapyridine, Prednisone and elemental diet during six week a significant drop in fecal lysozyme level was observed (p less than 0.01). In eighteen adolescent with Colitis ulcerosa and Crohn's disease the lysozyme level of colonic mucosa was found to be significant higher than a control group (p less than 0.01). The fecal lysozyme excretion can be used as an indicator for the clinical activity of the disease, as a control for therapeutic efficiency and a marker for a relapse.

Redox imbalance in Crohn's disease intestinal smooth muscle cells causes NF-kappaB-mediated spontaneous interleukin-8 secretion.

Interleukin-8 (IL-8), a chemokine secreted by cells at injury sites, has recently been recognized as involved in the pathogenesis of Crohn's disease. However, the pathogenesis of enhanced spontaneous transcription of IL-8 by the bowel in patients with Crohn's disease is undefined. Although IL-8 is secreted primarily by neutrophils, macrophages, and endothelial and epithelial cells, we observed the involvement of mesenchymal cells in the inflammatory process. A smooth muscle cell line isolated from the ileum of a patient with Crohn's disease (CDISM) and maintained in culture exhibited spontaneous transcription and secretion of IL-8 when compared with intestinal smooth muscle cells obtained from a normal subject (NHISM). Furthermore, IL-8 transcription from CDISM cells was associated with remarkable spontaneous activation of the oxidant-sensitive transcription factor NF-kappaB, as assessed by transient transfection assays with an IL-8 promoter reporter construct, Western blot analysis, and electrophoretic mobility shift assays (EMSA). Finally, we report here that CDISM cells exhibit significantly altered redox balance. The antioxidant pyrrolidine dithiocarbamate (PDTC) restored the redox equilibrium by mechanisms that inhibit binding of NF-kappaB to its cognate site on the IL-8 promoter. These findings suggest that restoration of the redox balance could hold promise for therapeutic intervention in Crohn's disease.

[99mTc-HMPAO leukocyte scintigraphy in inflammatory intestinal disease].

Eighteen patients, suspected of active inflammatory bowel disease, were investigated. The 99mTc-HMPAO-leucocyte scintigraphy was evaluated using the results of the simultaneous clinical examinations, which included clinical and biochemical parameters, small intestinal series, colonoscopy and, in two patients, operation, as reference. In agreement with the clinical examinations, the leucocyte scintigraphy indicated active inflammatory bowel disease in 14 of the 18 patients. The leucocyte scintigraphy disclosed inflammation in all of the 19 bowel segments, in which the clinical examinations indicated active inflammation. In three patients with Crohn's disease the scintigraphy indicated more extensive inflammation. A correlation between the scintigraphic activity and the Crohn's Disease Activity Index was found. However, the leucocyte scintigraphy did not seem useful as a disease activity index. The 99mTc-HMPAO-leucocyte scintigraphy seemed especially useful in severely ill patients and in patients suspected of relapse.

Upper gastro-intestinal disease in Scotland: a survey of practice amongst Scottish gastroenterologists.

Given the range of causes of upper gastrointestinal disease (UGD), the evolving role of Helicobacter pylori in its pathogenesis and the variety of treatments available, one might expect complex management strategies in the management of these diseases. The aim of this study was to determine the current management strategies used in peptic ulcer disease and gastritis in Scotland and to identify areas where large and clinically important variations in practice exist between gastro-intestinal specialists. Between June and September 1994, 130 gastro-intestinal physicians and surgeons were sent a postal questionnaire based on their response to four hypothetical clinical scenarios. Eighty-one (63%) correspondents returned completed questionnaires. The case histories related to: bleeding duodenal ulcer; peptic ulceration whilst taking non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids; management of dyspepsia in the young; and management of gastritis. Thirty-eight per cent of clinicians surveyed advocated the use of intravenous acid reducing agents in peptic ulcer bleeding. A total of 88% advocated endoscopic therapy in the presence of stigmata of recent haemorrhage and 5% suggested a follow up of endoscopy to confirm healing after ulcer bleeding. In treating the patient with ulcer while on NSAIDs, 45% of clinicians would use H2 receptor antagonists, 37% would use omeprazole, 14% misoprostol and 4% helicobacter eradication. Of the clinicians surveyed, 63% said they would investigate a 25-year-old patient with dyspepsia by endoscopy and 84% of these will biopsy for H. pylori. Empirical treatment was favoured by 37% and 4% considered a barium meal. There was no consensus in the treatment of gastritis. There exists considerable divergence of opinion between clinicians in investigation and treatment of upper gastrointestinal disease. The role of endoscopy, the type and duration of medical treatment of bleeding and non bleeding ulcer and gastritis require further, more detailed investigation. A consensus document would be warmly welcomed.
