Worsening of long-lasting diarrhea, abdominal discomfort and weight loss were main symptoms in a 27-year-old Moroccan woman who had lived in Germany for 18 years. Pseudomonas, salmonella and lamblia cysts were found in stools. Histological examination of the gastrointestinal tract showed immunoproliferative small intestinal disease (IPSID), characterized by atrophy of the villi and lymphoplasmocytic infiltrates. alpha 1-heavy chains were found immunohistologically in the biopsy specimen, but not in serum, urine or jejunal juice. HLA-typing gave evidence of A9. Antibiotic treatment was successful for almost one year. Clinical, histological and immunological diagnosis of IPSID in an African woman living for nearly 20 years in Europe shows that, besides environmental factors, genetic disposition is an essential factor in the development of IPSID.  相似文献

Immunoproliferative small intestinal disease (IPSID), a proliferative disorder affecting the intestinal immune system, has only been reported sporadically in India. Fifteen patients with malabsorption syndrome who were diagnosed to have IPSID were included in this study. Mucosal biopsies from all patients, full thickness surgical biopsies from 10 and autopsy material from four patients were examined by light microscopy and immunohistochemistry. The patients were predominantly young (aged 16-36 years) and male (13 of 15). Diarrhoea, weight loss, vomiting and abdominal pain were the major symptoms. The upper small bowel was involved in all cases. Involvement of large bowel was detected antemortem in three patients, but was found in all autopsied patients. Involvement of the stomach was noted in one patient at autopsy. Mesenteric lymph nodes were involved in all patients who underwent laparotomy. The plasmacytic infiltrate was uniformly positive for alpha-heavy chain, and either negative for light chain production or showed monotypic light chain production. Some of the blasts were also positive for alpha-heavy chain. Three patients died before therapy could be commenced. One patient with stage A disease is alive and clinically free of disease at 7 years. Of the remainder, there have been four long-term survivors with chemotherapy. Immunoproliferative small intestinal disease occurs in southern India and has characteristics similar to that in other parts of the world. Early diagnosis may improve outcome in this disease.  相似文献

PURPOSE: The clinicopathologic findings in 45 adult Chinese patients with primary small-intestinal lymphoma (PSIL) are described and compared with those in Western countries and in underdeveloped nations. The efficacy of combination chemotherapy is also assessed. PATIENTS AND METHOD: Six patients had immunoproliferative small-intestinal disease (IPSID) indicated by the presence of alpha-heavy chain protein (alpha-CP) in body fluids or tumor tissues. Thirty-nine patients had non-IPSID, including one with postrenal transplant lymphoma. Thirty-three non-IPSID patients received a minimum of four cycles of combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP). RESULTS: All IPSID patients presented with the clinical and laboratory features of severe intestinal malabsorption, and all had diffuse lymphoplasmacytic infiltration in the mucosa of the small bowel. Lymphomas were localized mainly in the jejunum and mesenteric nodes. The histologic subtypes were diffuse large cell in two, immunoblastic in three, and diffuse mixed in one. All patients responded poorly to chemotherapy, with a median survival duration of 10.5 months. The common presenting symptoms of the 39 non-IPSID patients included abdominal pain (90%), weight loss (31%), abdominal mass (26%), obstruction (26%), and perforation (23%). Diffuse large-cell and immunoblastic lymphomas constituted 82% of cases. Four patients had stage IE, 19 stage II 1E, and 16 stage 112E disease according to the Musshoff's criteria; 22 had bulky tumors and 19 had multiple tumors. The tumors were completely resected in 14 patients. Of 33 patients treated with combination chemotherapy, 73% achieved a complete remission. With a median follow-up duration of 90 months, there have been four relapses, with only one at the primary tumor site. The overall 5-year survival and disease-free survival rates for non-IPSID patients who were treated with chemotherapy were 59% and 54%, respectively. CONCLUSION: Intensive chemotherapy produces long-term disease-free survival in locally advanced non-IPSID PSIL.  相似文献

The screening value of the one-hour blood xylose test, corrected for body surface area, was prospectively studied in Saudi Arabian adults and children under investigation for suspected intestinal malabsorption. Sensitivity of discrimination between patients with and without upper small bowel disease was 91%, compared to 85% for the five-hour urine xylose test. Primary small bowel disorder was rare. In a three-year review, no cases of adult coeliac disease or tropical sprue were found. The most common causes of malabsorption were intestinal tuberculosis, abdominal lymphoma and immunoproliferative small intestinal disease. Despite its acceptability as an index of proximal small bowel function, the blood xylose test alone is an inadequate screening test for any of these conditions.  相似文献

AIMS: Five cases of primary gastrointestinal (GI) lymphoma (three in the stomach, one in the ileum (IPSID) and one in the colon) associated with localized AL amyloidosis were studied to identify morphological or immunohistochemical features which could explain the amyloid deposition. METHODS AND RESULTS: All the cases were low-grade marginal zone B-cell lymphomas; one case of gastric lymphoma and the IPSID also had a high-grade component. The lymphomas had a monoclonal plasma cell population, with different light and heavy-chain type expression in the five cases. Plasma cell differentiation was closely associated with the amyloid deposits. The latter were an incidental microscopic finding in one case, but produced tumoral masses in the other. CONCLUSIONS: The presence of amyloid in primary GI lymphoma is rare, but can have diagnostic value. In the present study, neither particular features of the lymphomatous proliferation nor specific agents are identified. Therefore, the factors predisposing to amyloid deposition require elucidation.  相似文献

Celiac disease is characterized by small intestinal damage with loss of absorptive villi and hyperplasia of the crypts, typically leading to malabsorption. In addition to nutrient deficiencies, prolonged celiac disease is associated with an increased risk for malignancy, especially intestinal T-cell lymphoma. Celiac disease is precipitated by ingestion of the protein gliadin, a component of wheat gluten, and usually resolves on its withdrawal. Gliadin initiates mucosal damage which involves an immunological process in individuals with a genetic predisposition. However, the mechanism responsible for the small intestinal damage characteristic of celiac disease is still under debate. Small intestinal biopsy with the demonstration of a flat mucosa which is reversed on a gluten-free diet is considered the main approach for diagnosis of classical celiac disease. In addition, IgA antibodies against gliadin and endomysium, a structure of the smooth muscle connective tissue, are valuable tools for the detection of patients with celiac disease and for therapy control. Incidence rates of childhood celiac disease range from 1:300 in Western Ireland to 1:4700 in other European countries, and subclinical cases detected by serological screening revealed prevalences of 3.3 and 4 per 1000 in Italy and the USA, respectively. IgA antibodies to endomysium are particularly specific indicators of celiac disease, suggesting that this structure contains one or more target autoantigens that play a role in the pathogenesis of the disease. However, the identification of the endomysial autoantigen(s) has remained elusive. We identified tissue transglutaminase as the unknown endomysial autoantigen. Interestingly, gliadin is a preferred substrate for this enzyme, giving rise to novel antigenic epitopes.  相似文献

The traditional definition of coeliac disease is inadequate because it includes only patients with abnormal small intestinal morphology. Gluten sensitivity is a systemic disorder whose common factor is an immune response to gluten in the context of the susceptible 'coeliac' HLA haplotype and possibly environmental triggers. Gluten sensitivity embraces traditional coeliac disease as well as subjects with normal small bowel morphology including latent coeliac disease, dermatitis herpetiformis, and symptomatic gluten intolerance. The diagnosis of gluten sensitivity and coeliac disease are not mutually inclusive. Small intestinal biopsy and clinical criteria are essential in diagnosing classical coeliac disease. IgA endomysial antibody is valuable in identifying gluten sensitivity and has particular value as a screening test. Serology should include total IgA levels to exclude selective IgA deficiency, a potential cause of false negative IgA endomysial antibody. A combination of histology, serology and clinical criteria will identify most cases of coeliac disease and gluten sensitivity.  相似文献

Idiopathic intestinal invagination is a relatively frequent process in children in comparison with cases of intestinal obstruction/subocclusion by invagination secondary to a tumor in adults which is unusual and more often observed in patients over the age of 60 years. Two clinical cases of intestinal obstruction in young adult males due to intestinal invagination by a tumor of the small intestine are presented. One case was due to a submucosal lipoma which lead to ileo-ileal intussusception and an ileo-cecal invagination by a terminal ileum lymphoma. The clinical and diagnostic aspects of this infrequent disease are discussed.  相似文献

The Authors discuss etiology, clinical picture, diagnostic and therapeutic possibilities of intestinal volvulus, an uncommon disease in Europe, thinking of a case of primitive small intestine volvulus, recently observed, and considering the literature. The Authors have come to the conclusion that in all the cases of intestinal occlusion, in emergency hospitalization, it is important to suspect the intestinal volvulus and to operate on the patient urgently to avoid the raise of postoperative mortality in all the cases complicated with intestinal gangrene.  相似文献

OBJECTIVE: To assess both the prevalence and the characteristics of motor disorders of the small bowel in patients with systemic sclerosis (SSc) and to investigate for an association between clinical manifestations in the upper intestinal tract, capillaroscopic features, esophageal motor impairment, and manometric evidence of motor disturbances. METHODS: Fasting and postprandial motor activity of the upper intestinal tract was studied in 17 consecutive patients with SSc (6 with and 11 without clinical manifestations of small bowel involvement) and 17 age- and sex-matched healthy control subjects. RESULTS: The prevalence of manometric evidence of intestinal involvement was as high as 88% in the SSc patients; normal motor activity was present in only 2 patients. The median values for duodenal and jejunal interdigestive phase III migrating motor complex duration, amplitude, and velocity and the postprandial motility index were therefore lower in SSc patients compared with controls. Our manometric findings indicated that there are both neuropathic and myopathic stages of upper intestinal tract dysfunction in SSc. Furthermore, no association could be found between the severity of the intestinal manometric abnormalities and clinical presentation, SSc subsets, disease score, capillaroscopic findings, or esophageal manometric impairment. CONCLUSION: We suggest that manometry of the upper intestinal tract may be useful in SSc patients with clinical manifestations in the small bowel (i.e., malabsorption syndrome or pseudoobstruction) in that it can be used to accurately evaluate both the nature and the severity of motor disturbances. Furthermore, this procedure can be used to assist in the selection of patients who may require octreotide therapy.  相似文献

BACKGROUND: Sufficient intraluminal concentrations of 5-aminosalicylic acid (ASA) within inflamed regions of the intestine are required for therapeutic efficacy in inflammatory bowel disease. Various oral delayed release preparations have been developed to ensure that 5-ASA is set free in those parts of the gut, which are most frequently affected. However, resulting intraluminal concentrations within the small bowel are unknown. Therefore, we determined and compared 5-ASA release within different segments of the small bowel from an Eudragit L coated 5-ASA preparation (Salofalk) and from an ethylcellulose coated microsphere preparation (Pentasa). METHODS: Twelve healthy subjects were intubated with an oro-ileal multilumen-tube for marker perfusion, duodenal, jejunal and ileal aspiration of chyme and intestinal manometry. Each subject received 500 mg 5-ASA (Salofalk, n = 6, or Pentasa, n = 6) together with a semiliquid test meal. Intestinal aspirates, blood and urine samples were obtained in regular intervals for 7 to 10 hours and were analysed for 5-ASA and its main metabolite acetyl-5-ASA by HPLC. RESULTS: With Salofalk, gastric emptying of 5-ASA did not take place in the digestive, but in the subsequent interdigestive period. Luminal delivery of 5-ASA and acetyl-5-ASA increased from the duodenum (3% of dose) to the ileum (30% of dose). 10% of the dose administered were excreted in urine and about 90% reached the colon unreleased or solubilised. By contrast, with Pentasa, 5-ASA was delivered to the duodenum together with the test meal and released continuously throughout the small intestine (about 20% of dose solubilised at each intestinal site). Only 3.5% of the dose administered were excreted in urine. Deliver of 5-ASA to the colon was equal to Salofalk. CONCLUSIONS: From both preparations, considerable amounts of 5-ASA are released during small intestinal transit thus explaining therapeutic efficacy in small intestinal Crohn's disease. Because of specific release patterns, Salofalk may be of use especially in terminal ileal disease, where as patients with extensive small intestinal disease including the proximal small intestine might benefit from Pentasa.  相似文献

BACKGROUND: The somatostatin analogue octreotide has been proposed as a possible therapeutic agent in patients with abnormal gastrointestinal motility. This study was conducted to study the effects of 0.5 microg/kg and 1.0 microg/kg subcutaneous octreotide on antroduodenal motility in children with chronic gastrointestinal disorders. METHODS: Twenty-three children were studied, eight with intestinal pseudo-obstruction, six with nonulcer dyspepsia, six with gastroesophageal reflux disease, and three with intractable constipation. After recording fasting motility for more than 4 hours, the children were randomized to receive 0.5 microg/kg or 1 microg/kg of subcutaneous octreotide. Motility was recorded for another hour after feeding in 12 children. RESULTS: Phase III of the motor migrating complex was present in 13 of 23 children before and in 21 after octreotide (p < 0.02). All phase III episodes after administration of octreotide except one originated in the small intestine. Phase IIIs after octreotide were longer and were propagated faster than the spontaneous phase IIIs. There were no antral contractions during fasting after octreotide. There was a significant decrease in phase II intestinal motor activity in the hour after administration of octreotide (p < 0.001). There was no difference in effect between the two doses. After feeding, antral contractions were present in all children, and intestinal phase IIIs were not abolished. CONCLUSIONS: In children with chronic bowel disorders, subcutaneous octreotide induced phase IIIs that differed from spontaneous phase IIIs and were not inhibited by meals. Octreotide decreased antral motility during fasting and inhibited intestinal phase II. Feeding abolished the inhibitory effect of octreotide on antral motility.  相似文献

There is a recognised association between the "microscopic" forms of colitis and coeliac disease. There are a variety of subtle small intestinal changes in patients with "latent" gluten sensitivity, namely high intraepithelial lymphocyte (IEL) counts, abnormal mucosal permeability, and high levels of secretory IgA and IgM antibody to gliadin. These changes have hitherto not been investigated in microscopic colitis. Nine patients (four collagenous, five lymphocytic colitis) with normal villous architecture were studied. Small intestinal biopsies were obtained by Crosby capsule; small intestinal fluid was aspirated via the capsule. IEL counts were expressed per 100 epithelial cells, and intestinal IgA and IgM antigliadin antibody levels were measured by ELISA. Small intestinal permeability was measured by the lactulose:mannitol differential sugar permeability test. IEL counts were normal in all cases, median 17, range 7-30. Intestinal antigliadin antibodies were measured in six cases and were significantly elevated in two patients (both IgA and IgM). Intestinal permeability was measured in eight cases and was abnormal in two and borderline in one. These abnormalities did not overlap: four of nine patients had evidence of abnormal small intestinal function. Subclinical small intestinal disease is common in the two main forms of microscopic colitis.  相似文献

Although intraoral involvement in Crohn's disease (CD) is observed in only approximately 9% of cases, oral inflammation precedes intestinal symptoms of CD in about 60% of these patients. We describe a 20-year-old male with recurrent, painful, intraoral lesions who presented no other signs of systemic disease apart from severe loss of body weight. From the routinely screened serological parameters only the erythrocyte sedimentation rate and the acute phase reactants were elevated. A biopsy from the vestibular mucosa revealed a dense mononuclear infiltrate and, focally, small noncaseating granulomas suggestive of CD. Gastrointestinal endoscopy was performed showing mucosal involvement reaching from the esophagus to the descending colon. The diagnosis of active CD was confirmed by histopathology of intestinal biopsy specimens. As oral lesions are sometimes treated without a definite diagnosis, we emphasize the need to search for underlying systemic illness in the differential diagnosis of recurrent inflammatory lesions of the oral cavity.  相似文献

Coeliac disease can by defined as a chronic disease characterized by a typical mucosal lesion of the small intestine and an impaired nutrient absorption which improves on withdrawal of gluten from the diet. The prevalence rate has increased over the last decades and just 1/3 of cases are diagnosed in childhood. There is a striking association with class II histocompatibility antigens, HLA-DR3 and HLA-DQ2. Cellular immune response mediated by intraepithelial and lamina propria lymphocytes is the primary event in the small intestine damage. Up to 50% of adult coeliac patients don't present intestinal symptoms being more frequent subclinic forms. The immunological markers of coeliac disease are antigliadin, antireticulin and antiendomysial antibodies, being the last one the most specific. Mortality of coeliac patient is increased mainly for malignancies, being the most frequent the intestinal T lymphoma.  相似文献

Of 503 patients with Crohn disease seen at the New York Hospital-Cornell Medical Center, 138 (28%) developed an anorectal abscess, anal fissure, or anal fistula during the course of their disease. In 9.3% of patients the anal lesion preceded the onset of intestinal symptoms by two weeks to 12 years. Patients in our series with large bowel disease were twice as likely to develop an anal lesion as were patients with small bowel disease. Likewise, patients with large bowel disease were twice as likely to have had an anal lesion as a presenting symptom. A patient with an anal lesion, however, was more apt to develop small bowel disease simply because the small bowel was a far commoner site of Crohn disease in this series. The cause of the anal lesions is still not clear. Specific evidence of Crohn disease was not found in histological examination of material from any of the patients.  相似文献

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.  相似文献

The effect of the putative enteric neurotransmitters neurokinin A and substance P were investigated on human small intestinal motility. Either neurokinin A, at doses of 6-25 pmol/kg/min, or substance P at doses of 1-6 pmol/kg/min were administered intravenously to healthy volunteers over 4 hr. Neurokinin A dose-dependently increased the fraction of phase II of the migrating motor complex, contraction frequency, motility index, and amplitude of contractions. At the highest dose, neurokinin A induced a phase II-like pattern, disrupting the migrating myoelectric complex. Substance P dose-dependently increased phase II of the migrating motor complex. The contraction frequency increased slightly at the highest dose, but neither motility index nor contraction amplitude changed. It is concluded that neurokinin A and substance P stimulate small intestinal motility in man, and it can be speculated that they play a role in the control of human small intestinal motility.  相似文献

BACKGROUND & AIMS: The etiology of refractory sprue is unclear. To gain insight into its pathogenesis, the phenotype and T-cell receptor (TCR) gene rearrangement status of intestinal lymphocytes were analyzed in a group of patients with clinical or biological features of celiac disease but either initially or subsequently refractory to a gluten-free diet. METHODS: Intestinal biopsy specimens were obtained from 26 adults: 6 patients with refractory sprue, 7 patients with active celiac disease, and 13 normal controls. The phenotype of intestinal lymphocytes was studied by immunohistochemistry and, in 3 patients with refractory sprue, by cytometry of lymphocytes purified from intestinal biopsy specimens. TCR rearrangements were assessed by studying TCRgammaV-J junctional regions from DNA extracted from intestinal biopsy specimens and purified intestinal lymphocytes. RESULTS: In the 6 patients with refractory sprue, but not in normal controls or patients with active celiac disease, the intestinal epithelium was massively infiltrated by small lymphocytes that lacked CD8, CD4, and TCR, contained intracytoplasmic but not surface CD3epsilon chains, and exhibited restricted TCRgamma gene rearrangements. CONCLUSIONS: Refractory sprue is associated with an abnormal subset of intraepithelial lymphocytes containing CD3epsilon and restricted rearrangements of the TCRgamma chain but lacking surface expression of T-cell receptors.  相似文献

A 7-week-old boy presented with a 6-week history of failure to thrive, acute intestinal obstruction, and an apparently irreducible intussusception (noted on contrast enema). He underwent abdominal exploration, during which a cecal mass was identified and resected. The mass proved to be a leiomyosarcoma. Histologically, it was an intermediate-grade malignancy with a predicted 5-year survival rate of 16% to 23% based on data from the adult experience. Three years after resection and without having received adjuvant therapy, he is healthy and free of disease. A review of the literature showed that in infants these tumors are predominantly colonic, compared with the predilection for small intestinal lesions found in the older pediatric and adult populations. Infantile intestinal leiomyosarcomata are rare malignancies that do well if complete surgical excision of the disease can be accomplished. The histological prognostic indicators proposed for intestinal leiomyosarcomas in the adult population cannot be extrapolated to infants because when they occur in infants, they appear to be less aggressive, and these patients do well without adjuvant therapy.  相似文献
