[Bacteriological, parasitological and virological study of the digestive flora in alpha-chain disease].

Intestinal flora was explored in twelve patients affected with alpha-chain disease at different stages (stage A: 2 cases; stage B: 6 cases; stage C: 4 cases). Bacterial overgrowth in the jejunum was observed in 11 cases, but intestinal flora was diverse and no one species was always present; although a 3-month oral antibiotic treatment induced complete remission in one patient (stage A) it was not possible to demonstrate any pathogenic bacterial species. Intestinal lambliasis was present in 40 p. 100 of cases. Virologic studies were negative. At stages A and B of the disease, antibiotic treatment was able to improve malabsorption and/or plasma protein digestive losses in 62 p. 100 of cases; this effect seemed related to the reduction of the bacterial flora and to giardiasis eradication.

A case of pediatric Behçet's disease with intestinal involvement.

We report a 6-year-old girl with recurrent oral aphthae, genital and perianal ulcers, and folliculitis-like erythema followed by intestinal symptoms. No ocular lesions were found. Her ailment was diagnosed as incomplete Behçet's disease with intestinal involvement. According to the literature, pediatric Behçet's disease is characterized by a low incidence of ocular lesions and a high incidence of intestinal involvement, as exhibited in this case. As intestinal lesions in pediatric Behçet's disease are often life-threatening, a barium enema must be given to exclude the possibility of intestinal involvement when pediatric patients with Behçet's disease complain of abdominal pain.

Therapeutic options in the management of strictures in Crohn's disease.

Intestinal strictures are a commonly encountered problem in patients with Crohn's disease. Endoscopic management with hydrostatic balloon dilation is an effective alternative to surgery in patients with endoscopically accessible lesions that are shorter than 7-8 cm. Endoscopic balloon dilation is the preferred initial modality in anastomotic strictures. The presence of inflammation near the stricture should not be considered a contraindication to dilation, and intralesional steroid injection should be considered in these patients with inflammation present in the area of the stricture. Further technological developments in endoscopes and balloon dilators may allow for broader application of these techniques.

Reactivity of infiltrating T lymphocytes with microbial antigens in Crohn's disease.

Intestinal T lymphocytes are normally unresponsive to microbial and recall antigens in vitro, whereas the same antigens induce strong immune responses in peripheral-blood-derived T cells. We obtained T lymphocytes from peripheral blood and from the non-inflamed and inflamed intestinal mucosa of 6 patients (3 male, 3 female; mean age 33 years) with Crohn's disease. The T cells were stimulated in vitro with a range of microbial antigens. Whereas T cells from normal mucosa were unresponsive, those from inflamed mucosa had a proliferative response comparable to that of the peripheral-blood-derived T cells. These findings suggest that physiologic unresponsiveness to luminal antigens is abrogated in the inflammatory lesions of Crohn's disease patients. Infiltrating T lymphocytes may therefore mediate chronic inflammation on encountering the many antigens present in the intestine.

Incidence of intestinal parasitic disease in an acquired immunodeficiency syndrome day-care center.

In June, 1986, the Bronx Municipal Hospital Center opened an acquired immunodeficiency syndrome day-care center to provide a quality educational experience for children infected with the human immunodeficiency virus. A major concern was the possibility of increasing secondary infections among these immunocompromised children by placing them in a group environment. One particular worry was intestinal parasitic disease, a serious public health problem in day-care centers throughout the United States. To minimize the risk of parasitic infections, scrupulous hygienic and monitoring procedures were instituted at the acquired immunodeficiency syndrome day-care center. This study reports the incidence of intestinal parasitic disease at the acquired immunodeficiency syndrome day-care center during its first 40 months of operation, encompassing 669 child-months of enrollment, with 131 stool specimens examined for ova and parasites. There were 2 cases of parasitic infection: Entamoeba histolytica in an asymptomatic 6-year-old and Giardia intestinalis in a 7-year-old with diarrhea. In neither case was there any secondary spread. None of the 15 children in diapers had a positive specimen, and we found no Cryptosporidium. Our experience suggests that with appropriate precautions human immunodeficiency virus-infected children can participate in a group day-care program without excessive risk for parasitic disease. Strict adherence to hygienic procedures may also decrease the risk of intestinal parasitic disease among healthy children attending day-care centers.

Juvenile myelomonocytic leukemia in a child with Crohn disease.

Intestinal adenocarcinoma is a well-known complication of inflammatory bowel disease. Hematologic malignancies, most commonly lymphoma or acute myeloid leukemia, represent a much less well-recognized complication of these disorders; these typically occur in adults with ulcerative colitis. We report a fatal case of juvenile myelomonocytic leukemia associated with monosomy 7 in a young child with a clinical history of Crohn disease. Neither the leukemia nor the cytogenetic aberration has been previously reported in a patient with inflammatory bowel disease. The aggressive disease course emphasizes the need for proper recognition and further study of this unusual complication.

Detection of Fcgamma binding protein antigen in human sera and its relation with autoimmune diseases.

Intestinal goblet cells of patients with ulcerative colitis and Crohn's disease highly express a binding protein of the Fc portion of IgG (FcgammaBP), which is entirely different from the Fcgamma receptors I,II, and III on neutrophils and macrophages. In this study, we proved the qualitative existence of FcgammaBP antigen in the sera of patients with rheumatoid arthritis and systemic lupus erythematosus, and, further, established a highly sensitive and quantitatively reproducible assay for FcgammaBP antigen in order to prevent the cross-reactivity of FcgammaBP with von Willebrand factor which has about 30% homology. This assay revealed a higher level of FcgammaBP antigen in the blood stream of patients with autoimmune diseases, especially progressive systemic sclerosis. This would suggest that abnormal production of autoantibodies reflects increased generation of FcgammaBP in goblet cells and its secretion into the circulation by an unknown mechanism.

Diagnostic accuracy of fecal elastase 1 assay in patients with pancreatic maldigestion or intestinal malabsorption: a collaborative study of the Italian Society of Pediatric Gastroenterology and Hepatology.

Several reports have indicated that fecal elastase-1 (EL-1) determination is a new, sensitive, and specific noninvasive pancreatic function test; however, very few patients with malabsorption due to small intestine diseases have been included in the previous studies. The aim of the study was to compare the diagnostic accuracy of fecal EL-1 and fecal chymotrypsin (FCT) in distinguishing between pancreatic maldigestion and intestinal malabsorption. Three groups of subjects were studied: group A included 49 patients with known cystic fibrosis (25 males, median age 5 years); group B included 43 subjects with various small intestine diseases (17 males, median age 6 years); and group C included 45 children without any history of gastrointestinal disease (22 males, median age 5 years). In all patients, stools were collected for 72 h on a standard diet and fecal EL-1, FCT, and steatocrit tests were performed. Both EL-1 and FCT were below normal limits in all CF patients with pancreatic maldigestion not treated with pancreatic enzyme (100% sensitivity for both assays); El-1, but not FCT, was also below normal in all the CF patients with pancreatic maldigestion treated with pancreatic extracts. Both EL-1 and FCT values in the CF group were significantly lower than in subjects with various small intestinal diseases and in children without any history of gastrointestinal disease (P < 0.0001). FCT, but not EL-1, values showed an inverse statistically significant correlation with steatocrit values in the whole CF group (P < 0.001); FCT was below normal in three of four CF patients with steatorrhea on pancreatic enzyme therapy. Both EL-1 and FCT had 100% specificity when calculated in children without any history of gastrointestinal disease; in contrast, specificity was 86% for EL-1 and 76% for FCT if we considered the control group with small intestinal diseases: low EL-1 was observed in two cases of intestinal giardiasis, two cases of short bowel syndrome, one case of celiac disease, and one case of intestinal pseudobstruction; FCT was abnormal in four cases of intestinal giardiasis, three cases of celiac disease, one case of short bowel syndrome, one case of Crohn's disease, and one case of intestinal pseudobstruction. Diagnostic accuracy was 92% for fecal EL-1 and 82% for FCT. Steatocrit values were over the normal limit in 11 patients with small intestine diseases; in 7/11 of these patients at least one of the pancreatic test results was below the normal limit. In conclusions, in patients with CF, fecal EL-1 determination is not more sensitive than FCT in identifying pancreatic maldigestion; however, fecal EL-1 assay is more specific than FCT determination in distinguishing pancreatic maldigestion from intestinal malabsorption.

Use of pulmonary hydrogen gas excretion to detect carbohydrate malabsorption in dogs.

Pulmonary H2 excretion was measured in 10 healthy dogs, in 6 dogs with pancreatic exocrine insufficiency, and in 6 dogs with chronic small intestinal disease. Concentration of expired H2 in fasted healthy dogs was 0.9 +/- 0.1 ppm (mean +/- SEM) and peak H2 concentration of 1.4 +/- 0.2 ppm was detected up to 8 hours after feeding. Dogs with pancreatic exocrine insufficiency had fasting expired H2 concentrations of 3.3 +/- 0.9 ppm, which increased to a mean peak H2 concentration of 28.8 +/- 2.0 ppm 6.5 hours after feeding. Following xylose administration, expired H2 concentrations increased from fasting concentrations of 3.6 +/- 0.9 ppm to peak at 19.0 +/- 2.0 ppm in 1.5 hours. Blood xylose concentrations were diagnostic for carbohydrate malabsorption in 4 of 6 dogs with pancreatic exocrine insufficiency. Plasma p-aminobenzoic acid concentration identified bentiromide maldigestion in all dogs with pancreatic exocrine insufficiency. In 3 pancreatic exocrine insufficient dogs tested, pancreatic enzyme replacement therapy partially corrected carbohydrate malabsorption. Fasting expired H2 concentration was 5.3 +/- 1.3 ppm in dogs with chronic small intestinal disease and increased to a peak H2 of 72.2 +/- 18.0 ppm 7 hours after feeding. Following administration of xylose to dogs with chronic small intestinal disease, fasting expired H2 concentration increased from 3.0 +/- 1.0 ppm to a peak of 35.5 +/- 7.2 ppm at 2 hours. Blood xylose concentration was abnormal in only 2 of 6 dogs with chronic small intestinal disease. Results of these studies indicate that expired H2 analysis can identify carbohydrate malabsorption in dogs with pancreatic exocrine insufficiency or chronic small intestinal disease, and that pulmonary H2 testing is more sensitive than xylose absorption testing for the identification of carbohydrate malabsorption.

[Topical beclomethasone dipropionate (BDP) in intestinal inflammatory diseases: the results of a multicentre trial].

The authors assessed the efficacy and tolerability of BDP in an open protocol using rectal enemas and suppositories and in a double-blind protocol vs mesalazine using rectal enemas. A total of 47 patients suffering from ulcerous rectocolitis were enrolled in the study and treated for 42 days while undergoing endoscopic, histologic and clinical controls. In conclusion, the authors affirm that BDP may represent a useful new therapeutic instrument in the treatment of slight to moderately severe forms of inflammatory intestinal disease.

Anaesthetic management of a patient with microvillus inclusion disease for intestinal transplantation.

We report the anaesthetic management of a 3-year-old-child with microvillus inclusion disease undergoing isolated small bowel transplantation. He required long-term total parenteral nutrition which was complicated with numerous episodes of catheter related sepsis. This resulted in thrombosis of the major blood vessels which critically restricted vascular access available for intravenous nutrition, becoming a life-threatening condition for the patient. Haemodynamic, respiratory parameters and urinary output were well preserved throughout the procedure. Besides a transitory increase in potassium following graft revascularization, biochemical changes were small. Anaesthetic management included comprehensive preoperative assessment, central venous angiography to depict accessibility of central and peripheral veins, assurance of additional vascular access through the intraoperative catheterization of the left renal vein, perioperative epidural analgesia and preservation of splanchnic perfusion to ensure implant viability.

[Effect of a liquid acidophilic mixture on the intestinal microbiocenosis of infant patients in the 1st months of life].

The effect of a liquid acidophilic mixture on intestinal biocenosis was studied in 10 premature infants aged 19 days to 1 1/2 months (Group I) with focal inflammation and neurological disorders after hypoxia in the perinatal period, and in 11 children aged 19 days to 3 1/2 months (Group II) with sepsis and intestinal diseases of staphylococcal, proteus and obscure etiology. Before application of the mixture, all the children demonstrated microbiocenosis disorders which were more remarkable in Group II. The liquid acidophilic mixture was shown to have a correcting action as regards lactobacilli, and the quantitative and qualitative composition of intestinal bacteria. The correcting effect exhibited by the mixture was found inadequate to neutralize an adverse effect of the infectious process and intense antibiotic therapy and chemotherapy on intestinal microbiocenosis in children of the first months of life suffering from sepsis and intestinal diseases, provided the mixture was used for 11-20 days.

Intestinal permeability in patients with coeliac disease and relatives of patients with coeliac disease.

The functional integrity of the small bowel is impaired in coeliac disease. Intestinal permeability, as measured by the sugar absorption test probably reflects this phenomenon. In the sugar absorption test a solution of lactulose and mannitol was given to the fasting patient and the lactulose/mannitol ratio measured in urine collected over a period of five hours. The sugar absorption test was performed in nine patients with coeliac disease with an abnormal jejunum on histological examination, 10 relatives of patients with coeliac disease with aspecific symptoms but no villous atrophy, six patients with aspecific gastrointestinal symptoms but no villous atrophy, and 22 healthy controls to determine whether functional integrity is different in these groups. The lactulose/mannitol ratio (mean (SEM) is significantly higher in both coeliac disease (0.243 (0.034), p < 0.0001)) and relatives of patients with coeliac disease (0.158 (0.040), p < 0.005)) v both healthy controls (0.043 (0.006)) and patients with aspecific gastrointestinal symptoms (0.040 (0.011)). The lactulose/mannitol ratio in relatives of coeliac disease patients was significantly lower than in the coeliac disease patient group (p = 0.04). The lactulose/mannitol ratio was the same in healthy controls and patients with aspecific gastrointestinal symptoms. It is concluded that the sugar absorption test is a sensitive test that distinguishes between patients with coeliac disease and healthy controls. The explanation for the increased permeability in relatives of patients with coeliac disease is uncertain. Increased intestinal permeability may be related to constitutional factors in people susceptible to coeliac disease and may detect latent coeliac disease. The sugar absorption test may therefore be helpful in family studies of coeliac disease.

Intestinal absorption of cholecalciferol and 25-hydroxycholecalciferol in patients with both Crohn's disease and intestinal resection.

We compared the intestinal absorption of cholecalciferol and 25-hydroxycholecalciferol in patients with Crohn's disease and resections of the small bowel. Patients were subgrouped into those with small (less than 100 cm), intermediate (100-300 cm), and large (greater than 300 cm) resections. [3H]cholecalciferol or [3H]25-hydroxycholecalciferol were given orally and serial blood samples were taken for measurement of plasma radiolabeled vitamin. Absorption of both forms of the vitamin decreased with extent of resection but 25-hydroxycholecalciferol absorption was always greater than that of cholecalciferol. When compared with normal control subjects, 25-hydroxycholecalciferol absorption in these patients was better maintained than that of cholecalciferol. These data indicate that vitamin D malabsorption reflects the extent of distal small-bowel resection in Crohn's disease. Treatment with oral cholecalciferol is sufficient in those with small or moderate resections but oral 25-hydroxycholecalciferol supplementation may be preferred in those with a severe short-bowel syndrome.

Monocyte/macrophage activation by normal bacteria and bacterial products: implications for altered epithelial function in Crohn's disease.

Intestinal immune cells are less reactive than those in the peripheral blood; however, such cells from patients with Crohn's disease may be more responsive to bacterial products. Our study examined if nonpathogenic bacteria or lipopolysaccharide (LPS), can affect epithelial function in the presence of monocytes/macrophages. Lamina propria mononuclear cells (LPMCs) and peripheral blood monocytes (PBMs) were obtained from patients with Crohn's disease and control patients. Filter-grown T84 epithelial monolayers were co-cultured with nonactivated or LPS-activated LPMCs or PBMs for 48 hours. Epithelial secretory [baseline short-circuit current (Isc) and DeltaIsc to forskolin] and barrier (transepithelial electrical resistance) parameters were measured in Ussing chambers. LPS-activated PBMs from both controls and patients with Crohn's disease significantly increased Isc ( approximately 300%) and reduced transepithelial electrical resistance ( approximately 40%). Epithelial function was not altered after co-culture with control LPMCs +/- LPS. However, LPMCs from patients with Crohn's disease spontaneously secreted tumor necrosis factor-alpha, and induced epithelial changes similar to those produced by LPS-activated PBMs. Co-culture with control Escherichia coli and PBMs induced comparable changes in epithelial physiology, which were abrogated by anti-tumor necrosis factor-alpha antibody. We conclude that LPMCs of patients with Crohn's disease are spontaneously activated, possibly by gram-negative luminal bacteria, and can directly cause significant alterations in epithelial ion transport and barrier functions.

Intestinal tuberculosis with abdominal complications: radiologic and pathologic features.

BACKGROUND: To investigate radiologic and pathological features of intestinal tuberculosis with abdominal complications. METHODS: Twenty-two patients with 23 surgically proven complications (nine intestinal obstructions, eight perforations, three fistulae, and three intestinal bleeds) were analyzed. Medical records, radiologic studies, and pathologic examinations were reviewed with special emphasis on searching for the common features in each group of complication. RESULTS: The most important single feature in seven of the nine patients with intestinal obstruction was the presence of stricture. In the remaining two patients, bowel adhesion was a primary cause of obstruction. In eight patients with intestinal perforation, both obstruction and ulcerations in the dilated proximal loop were the important features in six, and multiple deep ulcerations without obstruction was a primary cause in the remaining two. The common features in three patients with fistulae were focal or multiple strictures, severe adhesions, and fibrotic bowel wall. Intestinal bleeding originated from diffuse mucosal ulcerations. The abdominal complications occurred during antituberculous therapy in 10 of the 22 patients. CONCLUSION: Understanding the radiologic and pathologic features of intestinal tuberculosis with complications help in making an appropriate clinical decision for the treatment strategy. Close observation is necessary, especially in those patients who are acutely ill during antituberculous medical therapy.
