Smoking and intestinal absorption of oral polyethylene glycols in Crohn's disease.

Intestinal absorption of orally administered polyethylene glycols with molecular weights of 634-1250 was investigated in 55 patients with Crohn's disease and in 20 healthy controls and was related to smoking habits at the time of testing. In the Crohn patients the polyethylene glycol absorption was also related to smoking habits at the time of diagnosis. Absorption of polyethylene glycols was impaired in Crohn patients compared with controls, but within both groups no difference was found among smokers, ex-smokers, and never-smokers (p > 0.05). Among the Crohn patients, those who smoked at the time of diagnosis had less impaired absorption (p < 0.02) of the smaller polyethylene glycols (634-942 Da) than those who did not. These data do not support the concept of altered intestinal permeability as the mechanism by which smoking influences Crohn's disease.

Nitrosonapthol test for screening of small intestinal diarrheal disease in the dog.

The nitrosonapthol test, which qualitatively measures urinary excretion of 4-hydroxyphenylacetic acid and related compounds, was evaluated as a screening test for small intestinal disease in 60 dogs with chronic diarrhea. Test results were positive in 8 of 13 dogs with pancreatic exocrine insufficiency, in 8 of 12 dogs with small intestinal malabsorption, in 2 of 17 dogs with colitis, and in all of 14 dogs with normal gut function and in which the specific cause of diarrhea was not determined. Test results were negative in 4 dogs with functional (stress-induced) diarrhea and in 25 clinically normal dogs. Thus, the test results were positive in 30 of 39 (77%) dogs with confirmed small intestinal or pancreatic disease or in which small intestinal disease was the most likely diagnosis, and in only 2 of 21 (9.5%) dogs with large intestinal disease (P less than 0.001). In human medicine, positive test results have been associated with bacterial overgrowth in the small intestine. Accordingly, antibiotics were administered orally to 8 of the dogs with diarrhea of undetermined cause. In all treated dogs, antibiotic therapy resulted in improvement in fecal consistency, decreased frequency of defecation, and a change from a positive to a less strongly positive or negative reaction to the nitrosonapthol test. These findings suggested that the nitrosonapthol test is useful in the discrimination of small intestinal from large intestinal diarrhea and as a guide to the use of oral antibiotic therapy in dogs with chronic diarrhea of undetermined cause.

[Deficiency polyneuropathy secondary to immunoproliferative disease of the small intestine].

We report a new case of immunoproliferative small intestinal disease with neurological involvement expressed as deficiency polyneuropathy. In spite of non identifiable plasmatic paraprotein, the use of immunohistochemical techniques showed the characteristic proliferation in the intestinal mucosa of plasma cells with a prevalence of IgA cells, which define this disease.

[The potentials of intestinoscopy and guided biopsy in the diagnosis of diseases of the small intestine].

AIM: To ascertain the role of intestinoscopy in diagnosis of small intestinal diseases. MATERIALS AND METHODS: Intestinoscopy with multiple topographic biopsies was made with SIF-10 device (Olympus) in 92 patients. RESULTS: Of 60 patients with absorption disorders, the diagnosis of gluten enteropathy (GEP), Whipple's disease (WD), general variable hypogammaglobulinemia (GVHG) and small intestinal diverticulum was established in 38, 3, 5 and 1 patients, respectively. 13 patients with mild malabsorption were free of the pathology. GEP, amyloidosis, intestinal lymphangiectasia were found in 5, 3 and 4 of 15 patients with exudative enteropathy. The rest had lymphoma, lymphangiomatosis, Crohn's disease. 11 patients with focal affections had Crohn's disease, polyps, GVHG or had only motor defects. Repeated intestinal hemorrhages in a few patients were due to adenocarcinoma, aberrant pancreas, intestinal or gastric erosions. CONCLUSION: Patients with malabsorption and exudative enteropathy had similar abnormalities in the small intestine and duodenum. Endoscopic biopsy from the distal duodenum is enough for diagnosis of GEP, Whipple's disease and GVHG. Intestinoscopy as well as x-ray imaging are effective in detection of focal lesions of the small intestine and sources of intestinal bleeding.

Ileal perforation in diffuse intestinal Behçet disease: report of a case.

Intestinal ulcers in Behçet disease tend to cause perforation, and postoperative recurrence is common with a high mortality rate. The optimal therapeutic strategy has yet to be elucidated, particularly in cases of diffuse intestinal involvement. We herein present a case of diffuse intestinal Behçet disease with ileal perforation. A 57-year-old Japanese woman was referred to our institution with complaints of intractable oral ulcers and abdominal pain. The patient underwent an emergency laparotomy for perforated peritonitis in spite of the intravenous administration of prednisolone (1.5 mg/kg) under total parenteral nutrition. Macroscopically, an inflamed ileum measuring 1.6 m in length was resected, including a 1-cm perforated ulceration. Innumerable small and deep ulcers were also observed, consisting of nonspecific inflammation. The patient has been free from any recurrence of intestinal ulcers while being treated with prednisolone, colchicine, and a low-residue diet for 1.5 years.

Alpha 1-antitrypsin, a reliable endogenous marker for intestinal protein loss and its application in patients with Crohn's disease.

Intestinal protein loss is generally determined by radio-labelled macromolecules. Alpha 1-antitrypsin has been proposed as an endogenous marker for protein losing enteropathy, but different opinions exist about its reliability. In 25 patients with Crohn's disease faecal protein loss was studied with intestinal alpha 1-antitrypsin (alpha 1AT) clearance. Simultaneously, in 10 patients alpha 1AT clearance was compared with faecal 51Cr clearance after intravenous 51Cr-albumin injection. There was a linear relation (p less than 0.05) between alpha 1AT clearance and 51Cr clearance in these cases. In all patients alpha 1AT clearance was raised above control values. alpha 1AT clearance, however, did not correlate with the activity index of Crohn's disease. This index does not contain direct criteria of intestinal inflammation, does not take into account localisation or extent of inflammation, and includes complications such as extraintestinal manifestations, fistuli, stenoses not necessarily related to actual mucosal involvement. It is concluded that alpha 1AT is a reliable marker for intestinal protein loss and that the intestinal changes of Crohn's disease generally lead to an increased protein exudation into the gut.

Studies of intestinal permeability in inflammatory diseases using polyethylene glycol 400.

It has been proposed that increased bowel permeability might play a role in the pathogenesis of inflammatory disease. Intestinal permeation was investigated by measuring the 6-hour urinary excretion of polyethylene glycol (PEG) 400 in 40 adult volunteer controls and in patients with inflammatory disease. Of the patients, 15 had Crohn's disease; 7, ulcerative colitis; 2, celiac disease; and 7, rheumatoid arthritis. No significant difference in total urinary excretion over a 6-hour period was found between controls and patients with ulcerative colitis. Patients with Crohn's disease, celiac disease, or with rheumatoid arthritis were found to have significantly decreased urinary excretion of PEG 400. The results of this study indicate that there is no identifiable increase in intestinal permeation as measured by PEG 400 excretion during periods of active inflammatory disease.

[The role of pathomorphologic diagnosis in differentiating intestinal inflammatory diseases].

The principles of collaboration between a gastrologist and a pathomorphologist in diagnosis of the intestinal diseases were presented. The optimal criteria of drawing and fixing cytological and tissue samples were presented. The importance of extensive clinical information for pathomorphological diagnosis was proved. It was indicated that an early collaboration between a gastrologist and a pathomorphologist in the process of clinical diagnostic planning is necessary.

[Immunoproliferative disease of the small intestine. Report of a case].

We report one case of immunoproliferative small intestinal disease with two rare characteristics. Firstly, the detection of monoclonal IgA-Kappa in serum and in the intestinal infiltrate and secondly, the advanced age of the patient at diagnosis. We checked up on Spanish literature and found an important number of patients that were diagnosed at such an age. We suggest that this disease may appear in elderly people in developed countries.

Increased orocecal transit time in patients with nonalcoholic fatty liver disease.

Intestinal bacterial overgrowth (IBO) has been suggested to play a pathogenic role in patients with nonalcoholic fatty liver disease (NAFLD). Delayed intestinal transit may contribute to IBO development. Ten nondiabetic patients with NAFLD and abnormal liver enzymes were recruited. Ten healthy individuals, matched by sex, age, and body mass index, were used as controls. Orocecal transit time (OCTT) was measured by the lactulose breath test. Anti-endotoxin core antibodies (EndoCAb) were determined. The effect of oral norfloxacin (400 mg BID during 2 weeks) on liver enzymes, lactulose breath test, and EndoCAb was also studied. NAFLD patients had higher basal breathed H2 and prolonged OCTT compared to controls (127 +/- 61 vs. 57 +/- 23 min, respectively; P = 0.0037). EndoCAb titers were similar in NAFLD patients and controls. Norfloxacin administration had no effect on ALT levels, lactulose breath test, or EndoCAb titers in patients with NAFLD. The present data show evidence of deranged intestinal motility in nondiabetic patients with NAFLD and support the hypothesis that NAFLD could be linked to endotoxin-induced liver damage of intestinal origin.

Review article: Pathophysiology of the intestinal mucosa in inflammatory bowel disease and arthritis: similarities and dissimilarities in clinical findings.

Although apparently dissimilar in both structure and function, the gut and locomotor system are linked by a number of clinical syndromes in which both are involved. In inflammatory bowel disease, intestinal mucosal inflammation is the primary problem, but may be associated with both axial and peripheral arthropathies. In the seronegative spondyloarthropathies the primary problem is in the locomotor system, but intestinal abnormalities may also be present. In addition, non-steroidal anti-inflammatory drugs used in their treatment, may cause a distinct enteropathy which may be confused with the disease-related intestinal abnormalities. The clinical, histological and genetic features of these conditions are examined in order to assess their relationship and the central role of the intestinal mucosa in their pathogenesis.

Similarities in intestinal humoral immunity in dermatitis herpetiformis without enteropathy and in coeliac disease.

Intestinal humoral immunity was examined in eight patients with dermatitis herpetiformis and normal jejunal histology (as determined by quantitative morphometry) on a gluten-containing diet. Jejunal aspirate was taken at the time of jejunal biopsy, and levels of total immunoglobulins (IgA, IgM, IgG) and specific antibody to gliadin and two other dietary proteins, betalactoglobulin and ovalbumin, were measured. The pattern of secretory immune responses in the dermatitis herpetiformis patients was similar to that in twenty-six patients with untreated coeliac disease--ie, higher than normal concentrations of IgA, IgM, and IgG and high levels of specific antibodies (IgA and IgM) to the three dietary proteins. Serum levels of IgA antigliadin were similar in the dermatitis herpetiformis and control (twenty-eight patients who underwent jejunal biopsy to exclude coeliac disease) groups, and serum levels of IgG antigliadin were intermediate between those of the control and coeliac disease groups. These findings suggest that investigation of gut humoral immunity may provide a diagnostic index of latent coeliac disease. The definition of coeliac disease as a permanent gluten-sensitive enteropathy may have to be revised if the proposed two-stage model is confirmed.
