Abstract
Food protein-induced enterocolitis syndrome (FPIES) represents a non-IgE-mediated food allergic disorder with delayed gastrointestinal symptoms that may evolve in a medical emergency. Clinically, FPIES can be distinguished into acute and chronic phenotypes. FPIES is mainly diagnosed in infancy however the onset at older ages is being progressively described. The pathogenetic mechanism underlying FPIES remains mainly unexplained, but an alteration of food-specific T-cell response has been proposed. The diagnosis of FPIES is primarily clinical, since there are not available specific biomarkers. Oral food challenge (OFC) is the gold standard for diagnosing FPIES or excluding the onset of tolerance to the triggering food. Management of FPIES includes an acute phase treatment and a maintenance therapy with the strict food avoidance until challenge, in order to prevent new attacks and avoid nutritional alterations. Acute management requires hydration that can be performed orally or intravenously according to clinical status. Long-term management of FPIES is based on the avoidance of the culprit food(s) and supervised introduction of other high-risk foods if never taken before among infants before 12 months of age. There is a compelling need of future achievements in FPIES research for the definition of underlying disease pathogenesis and potential therapeutic point of care.

Abstract
Non-immunoglobulin E-mediated gastrointestinal food allergic disorders (non-IgE-GI-FA) include food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE) and food protein-induced allergic proctocolitis (FPIAP), which present with symptoms of variable severity, affecting the gastrointestinal tract in response to specific dietary antigens. The diagnosis of non-IgE-GI-FA is made clinically, and relies on a constellation of typical symptoms that improve upon removal of the culprit food. When possible, food reintroduction should be attempted, with the documentation of symptoms relapse to establish a conclusive diagnosis. Management includes dietary avoidance, nutritional counselling, and supportive measures in the case of accidental exposure. The prognosis is generally favorable, with the majority of cases resolved before school age. Serial follow-up to establish whether the acquisition of tolerance has occurred is therefore essential in order to avoid unnecessary food restriction and potential consequent nutritional deficiencies. The purpose of this review is to delineate the distinctive clinical features of non-IgE-mediated food allergies presenting with gastrointestinal symptomatology, to summarize our current understanding of the pathogenesis driving these diseases, to discuss recent findings, and to address currents gaps in the knowledge, to guide future management opportunities.

Abstract
OBJECTIVE To provide a complete, exhaustive summary of current literature relevant to food protein-induced enterocolitis syndrome (FPIES). DATA SOURCES Data have been extracted from PubMed and Science Direct databases. STUDY SELECTIONS Following the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, a literature search for peer-reviewed journal articles in English through January 1975 with updates through October 2016 was conducted. Relevant publications were reviewed that included pediatric and adult populations. Information on the study design, sample, intervention, comparators, outcome, timeframe, and risk of bias were abstracted for each article. RESULTS Of 135 reviewed reports, 52 were included in this systematic review. In accordance with the age at onset, clinical features, and offending foods, it is possible to distiguish different types of FPIES. An immune systemic involvement can occur in patients with FPIES. In addition to the most common causative foods (cow's milk, soy, and rice), any food can potentially cause FPIES. Although specific diagnostic tests are not available, open food challenge remains the gold standard for FPIES diagnosis. Moreover, because of the lack of randomized clinical trials and of use of different adopted methods, confounding factors might mask critical findings, leading to poor knowledge of this pleiotropic clinical entity. CONCLUSION Multicenter studies are needed to better develop an evidence-based approach to pathophysiology, prevalence, diagnosis, and natural history of the disease.

Abstract
Gastrointestinal (GI) diseases comprise a large spectrum of clinical conditions ranging from indigestion to inflammatory bowel diseases (IBDs) and carcinomas. Endoscopy is the usual method employed to diagnose these condition. Another noninvasive way to assess and diagnose GI conditions are fecal biomarkers. Fecal biomarkers provide information regarding a specific disease process and are perhaps more acceptable to clinicians and patients alike because of their non-invasivity compared to endoscopy. Aim of this review was to evaluate the current status of the fecal biomarkers in clinical and research for in GI diseases. Multiple types of fecal biomarkers are discussed in this review including; markers to assess IBD, which are released as a results of an inflammatory insults to intestinal epithelia such as antimicrobial peptides (lactoferrin) or inflammation related proteins (calprotectin). While markers related to function of digestion are primarily related to partially digested food or mucosal proteins such as abnormal amount of fecal fat α1-antitrypsin, elastase and secretary IgA. The upcoming fecal biomarker like M2 pyruvate kinase and neutrophil gelatinase associated lipocalin are discussed as well. Apart from above mention, the fecal biomarkers under exploration for possible clinical use in future are also discussed. These include cathelicidins, osteoprotegerin, β-glucuronidase, Eosinophil proteins, etc.

Abstract
The technically easier one-anastomosis (mini) gastric bypass (MGB) is associated with similar metabolic improvements and weight loss as the Roux-en-Y gastric bypass (RYGB). However, MGB is controversial and suspected to result in greater malabsorption than RYGB. In this study, we compared macronutrient absorption and intestinal adaptation after MGB or RYGB in rats. Body weight and food intake were monitored and glucose tolerance tests were performed in rats subjected to MGB, RYGB, or sham surgery. Carbohydrate, protein, and lipid absorption was determined by fecal analyses. Intestinal remodeling was evaluated by histology and immunohistochemistry. Peptide and amino acid transporter mRNA levels were measured in the remodeled intestinal mucosa and those of anorexigenic and orexigenic peptides in the hypothalamus. The MGB and RYGB surgeries both resulted in a reduction of body weight and an improvement of glucose tolerance relative to sham rats. Hypothalamic orexigenic neuropeptide gene expression was higher in MGB rats than in RYGB or sham rats. Fecal losses of calories and proteins were greater after MGB than RYGB or sham surgery. Intestinal hyperplasia occurred after MGB and RYGB with increased jejunum diameter, higher villi, and deeper crypts than in sham rats. Peptidase and peptide or amino acid transporter genes were overexpressed in jejunal mucosa from MGB rats but not RYGB rats. In rats, MGB led to greater protein malabsorption and energy loss than RYGB. This malabsorption was not compensated by intestinal overgrowth and increased expression of peptide transporters in the jejunum.

Int Arch Allergy Immunol 2015; 168:61-8. [PMID: 26588792 DOI: 10.1159/000441471] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2014] [Accepted: 09/29/2015] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Food protein-induced allergic proctocolitis (FPIAP) is mostly a non-immunoglobulin E-mediated disease where a T-cell-mediated reaction to cow's milk protein has been suggested. We determined the expression of transforming growth factor (TGF)-β, TGF-β receptor-1, tumor necrosis factor (TNF)-α, CD86, and CD23 on the colon mucosa to investigate their roles in the pathogenesis of the two subtypes of FPIAP, i.e. infantile FPIAP and FPIAP in older children. METHODS Group 1 comprised children with infantile FPIAP (age <6 months, n = 21), group 2 referred to FPIAP in older children (age >1.5 years, n = 7), and group 3 included children with juvenile hyperplastic polyps (n = 22). Immunohistochemical staining of colonic biopsy specimens was performed. RESULTS The expression of TNF-α was significantly higher in groups 1 and 2 compared to group 3. Group 2 patients had a significantly lower TGF-β expression compared to the other groups. The expression of CD86 was higher in group 1 than in group 3 (p = 0.012). Eosinophil counts per high-power field in the lamina propria were significantly correlated with CD86 expression (p = 0.026, r = 0.388). CONCLUSION Our results suggest that TNF-α is implicated in the pathogenesis of both types of FPIAP. The decreased activity of TGF-β receptor-1 accompanied by the increased expression of CD86 in infants and the decreased activity of TGF-β in older children appear to play a role in the development of FPIAP.

Abstract
Colonization of the fetal and infant gut microbiome results in dynamic changes in diversity, which can impact disease susceptibility. To examine the relationship between human gut microbiome dynamics throughout infancy and type 1 diabetes (T1D), we examined a cohort of 33 infants genetically predisposed to T1D. Modeling trajectories of microbial abundances through infancy revealed a subset of microbial relationships shared across most subjects. Although strain composition of a given species was highly variable between individuals, it was stable within individuals throughout infancy. Metabolic composition and metabolic pathway abundance remained constant across time. A marked drop in alpha-diversity was observed in T1D progressors in the time window between seroconversion and T1D diagnosis, accompanied by spikes in inflammation-favoring organisms, gene functions, and serum and stool metabolites. This work identifies trends in the development of the human infant gut microbiome along with specific alterations that precede T1D onset and distinguish T1D progressors from nonprogressors.

Abstract
Food allergies are classified into three types, "IgE-mediated," "combined IgE- and cell-mediated" and "cell-mediated/non-IgE-mediated," depending on the involvement of IgE in their pathogenesis. Patients who develop predominantly cutaneous and/or respiratory symptoms belong to the IgE-mediated food allergy type. On the other hand, patients with gastrointestinal food allergy (GI allergy) usually develop gastrointestinal symptoms several hours after ingestion of offending foods; they belong to the cell-mediated/non-IgE-mediated or combined IgE- and cell-mediated food allergy types. GI allergies are also classified into a number of different clinical entities: food protein-induced enterocolitis syndrome (FPIES), food protein-induced proctocolitis (FPIP), food protein-induced enteropathy (Enteropathy) and eosinophilic gastrointestinal disorders (EGID). In the case of IgE-mediated food allergy, the diagnostic approaches and pathogenic mechanisms are well characterized. In contrast, the diagnostic approaches and pathogenic mechanisms of GI allergy remain mostly unclear. In this review, we summarized each type of GI allergy in regard to its historical background and updated clinical features, offending foods, etiology, diagnosis, examinations, treatment and pathogenesis. There are still many problems, especially in regard to the diagnostic approaches for GI allergy, that are closely associated with the definition of each disease. In addition, there are a number of unresolved issues regarding the pathogenic mechanisms of GI allergy that need further study and elucidation. Therefore, we discussed some of the diagnostic and research issues for GI allergy that need further investigation.

Abstract
BACKGROUND Small bowel transplantation has now become a recognized treatment of irreversible, permanent, and subtotal intestinal failure. OBJECTIVE The aim of this study was to assess intestinal absorption at the time of weaning from parenteral nutrition in a series of children after intestinal transplantation. DESIGN Twenty-four children (age range: 14-115 mo) received intestinal transplantation, together with the liver in 6 children and the colon in 16 children. Parenteral nutrition was slowly tapered while increasing enteral tube feeding. The absorption rate was measured from a 3-d stool balance analysis performed a few days after the child had weaned from parenteral nutrition to exclusive enteral tube feeding. Results were analyzed according to the resting energy expenditure (REE; Schofield formula). RESULTS All children were weaned from parenteral nutrition between 31 and 85 d posttransplantation. Median intakes were as follows: energy, 107 kcal · kg(-1) · d(-1) (range: 79-168 kcal · kg(-1) · d(-1)); lipids, 39 kcal · kg(-1) · d(-1) (range: 20-70 kcal · kg(-1) · d(-1)); and nitrogen, 17 kcal · kg(-1) · d(-1) (range: 11-27 kcal · kg(-1) · d(-1)). Median daily stool output was 998 mL/d (range: 220-2025 mL/d). Median absorption rates were 88% (range: 75-96%) for energy, 82% (range: 55-98%) for lipids, and 77% (range: 61-88%) for nitrogen. The ratios for ingested energy to REE and absorbed energy to REE were 2.2 (range: 1.6-3.6) and 1.8 (range: 1.3-3.3), respectively. CONCLUSION These data indicate a suboptimal intestinal graft absorption capacity with fat malabsorption, which necessitates energy intakes of at least twice the REE.

Abstract
Our objective was to understand the functional link between the composition of faecal microbiota and the clinical characteristics of adults with short bowel syndrome (SBS). Sixteen patients suffering from type II SBS were included in the study. They displayed a total oral intake of 2661±1005 Kcal/day with superior sugar absorption (83±12%) than protein (42±13%) or fat (39±26%). These patients displayed a marked dysbiosis in faecal microbiota, with a predominance of Lactobacillus/Leuconostoc group, while Clostridium and Bacteroides were under-represented. Each patient exhibited a diverse lactic acid bacteria composition (L. delbrueckii subsp. bulgaricus, L. crispatus, L. gasseri, L. johnsonii, L. reuteri, L. mucosae), displaying specific D and L-lactate production profiles in vitro. Of 16 patients, 9/16 (56%) accumulated lactates in their faecal samples, from 2 to 110 mM of D-lactate and from 2 to 80 mM of L-lactate. The presence of lactates in faeces (56% patients) was used to define the Lactate-accumulator group (LA), while absence of faecal lactates (44% patients) defines the Non lactate-accumulator group (NLA). The LA group had a lower plasma HCO3− concentration (17.1±2.8 mM) than the NLA group (22.8±4.6 mM), indicating that LA and NLA groups are clinically relevant sub–types. Two patients, belonging to the LA group and who particularly accumulated faecal D-lactate, were at risk of D-encephalopathic reactions. Furthermore, all patients of the NLA group and those accumulating preferentially L isoform in the LA group had never developed D-acidosis. The D/L faecal lactate ratio seems to be the most relevant index for a higher D- encephalopathy risk, rather than D- and L-lactate faecal concentrations per se. Testing criteria that take into account HCO3− value, total faecal lactate and the faecal D/L lactate ratio may become useful tools for identifying SBS patients at risk for D-encephalopathy.

Abstract
BACKGROUND Segmental reversal of the small bowel (SRSB) is proposed in patients with short-bowel syndrome (SBS) as a rehabilitative therapy, but its effects on absorption have not been studied. OBJECTIVE We aimed to determine intestinal macronutrient absorption and home parenteral nutrition (HPN) dependence in SBS patients with intestinal failure. DESIGN We included in a retrospective study all consecutive patients who had an SRSB between 1985 and 2010 and underwent a study of macronutrient absorption. Patients were matched to SBS controls with the same digestive characteristics. Energy and macronutrient absorption were measured. The dependence on HPN was expressed by the number of infusions per week and by the calories infused daily divided by the basal energy expenditure multiplied by 1.5. RESULTS Seventeen patients who had an SRSB were matched to 17 control patients. Intestinal absorption was higher in the SRSB group for total calories (69.5% compared with 58.0%), fat (48.4% compared with 33.2%), and protein (62.7% compared with 53.4%) (P < 0.05). Median oral autonomy was 100% ± 38.4% in the SRSB group, whereas it was 79% ± 39.6% in the control group (P < 0.05). The number of calories infused was lower in the SRSB group (500 ± 283 compared with 684 ± 541; P < 0.05), as was HPN dependence (33% ± 20% compared with 48% ± 38%; P < 0.05) at the time of the study. CONCLUSION SRSB allows a gain in macronutrient absorption, which is associated with a lower HPN dependence. To our view, SRSB should be integrated in intestinal rehabilitative adult programs.

Abstract
Food protein-induced enterocolitis syndrome (FPIES) is an under-recognized and frequently misdiagnosed non-IgE-mediated food hypersensitivity disorder, characterized by severe vomiting and/or diarrhea. Despite the potential severity of acute reactions, FPIES can be considered self-limiting as avoidance of the incriminating allergen(s) leads to resolution of symptoms. Symptoms typically begin in the first month of life in association with failure to thrive and may progress to acidemia and shock. Although FPIES is well established as a distinct clinical entity, its pathophysiology has not yet been clearly defined and requires further characterization. Several immunologic alterations have been reported in FPIES, suggesting the involvement of antigen-specific T cells and their production of proinflammatory cytokines that regulate the permeability of the intestinal barrier. Humoral immune responses may also be involved in the pathomechanism of FPIES. The aim of this article is to delineate the immunological characteristics of this disorder based on the existing reports and to review the possible pathophysiologic basis of this disease.

Abstract
Intestinal bacterial colonisation in pre-term infants is delayed compared with full-term infants, leading to an increased risk of gastrointestinal disease. Modulation of colonisation through dietary supplementation with probiotics or prebiotics could decrease such a risk. The present study evaluated clinical tolerance, the effects on gut microbiota, and inflammatory and immunological mucosal responses to an infant formula adapted for pre-term infants that included in its manufacturing process a fermentation step with two probiotic strains, Bifidobacterium breve C50 and Streptococcus thermophilus 065, inactivated by heat at the end of the process. A total of fifty-eight infants (gestational age: 30–35 weeks), fed either the fermented pre-term formula or a standard pre-term formula, were followed up during their hospital stay. Clinical tolerance, faecal microbiota using a culture and a culture-independent method (temporal temperature gel electrophoresis), faecal calprotectin and secretory IgA were analysed weekly. No difference was observed regarding anthropometric data and digestive tolerance, except for abdominal distension, the incidence of which was lower in infants fed the fermented formula for 2 weeks. Bacterial colonisation was not modified by the type of feeding, particularly for bifidobacteria. Faecal calprotectin was significantly lower in infants fed the fermented formula for 2 weeks, and secretory IgA increased with both mother's milk and the fermented formula. The fermented formula was well tolerated and did not significantly modulate the bacterial colonisation but had benefits on inflammatory and immune markers, which might be related to some features of gastrointestinal tolerance.

Abstract
This prospective study aimed to establish the effect of recombinant human growth hormone (rhGH) on intestinal function in children with short bowel syndrome (SBS). Eight children with neonatal SBS were included. All were dependent on parenteral nutrition (PN) for >3 years (range, 3.8-11.6 years), with PN providing >50% of recommended dietary allowance for age (range, 50%-65%). The subjects received rhGH (Humatrope) 0.13 mg/kg/d subcutaneously over a 12-week period. The follow-up was continued over a 12-month period after rhGH discontinuation. Clinical and biological assessments were performed at baseline, at the end of the treatment period, and 12 months after the end of treatment. No side effects related to rhGH were observed. PN requirements were decreased in all children during the course of rhGH treatment. Between baseline and the end of treatment, significant increases were observed in concentrations (mean ± standard deviation) of serum insulin-like growth factor 1 (103.1 ± 49.9 µg/L vs 153.5 ± 82.2 µg/L; P < .01), serum insulin-like growth factor-binding protein 3 (1.7 ± 0.6 mg/L vs 2.5 ± 0.9 mg/L; P < .001), and plasma citrulline (16.5 ± 14.8 µmol/L vs 25.2 ± 18.3 µmol/L; P < .05). A median 54% increase in enteral intake (range, 10%-244%) was observed (P < .001) and net energy balance improved significantly (P < .002). It was necessary for 6 children to be maintained on PN or restarted after discontinuation of rhGH treatment, and they remained on PN until the end of the follow-up period. A 12-week high-dose rhGH treatment allowed patients to decrease PN, but only 2 patients could be definitively weaned from PN. Indications and cost-effectiveness of rhGH treatment for SBS pediatric patients need further evaluation.

Abstract
Fat oxidation (FO) is optimized during low- to moderate-intensity exercise in lean and obese subjects, whereas high-intensity exercise induces preferential FO during the recovery period. After food intake during the postexercise period, it is unknown if FO differs according to the intensity exercise in overweight subjects. Fat oxidation was thus evaluated in overweight men after low- and high-intensity exercise during the recovery period before and after food intake as well as during a control session. Ten healthy, sedentary, overweight men (age, 27.9 +/- 5.6 years; body mass index, 27.8 +/- 1.3 kg m(-2); maximal oxygen consumption, 37 +/- 3.9 mL min(-1) kg(-1)) exercised on a cycloergometer (energy expenditure = 300 kcal) at 35% (E35) or 70% (E70) maximal oxygen consumption or rested (Cont). The subjects were fed 30 minutes after the exercise with 300 kcal (1256 kJ) more energy in the exercise sessions than in the Cont session. Respiratory quotient and FO were calculated by indirect calorimetry. Blood samples were analyzed to measure plasma glycerol, nonesterified fatty acid, glucose, and insulin. During exercise, mean respiratory quotient was lower (P < .05) and FO was higher (P < .01) in the E35 than in the E70 session (FO [in mg min(-1)]: E35 = 290 +/- 12, E70 = 256 +/- 38, and Cont = 131 +/- 7). Conversely, FO was higher in the E70 than in both the E35 session and the Cont session during the immediate recovery as well as during the postprandial recovery period (P = .005 for all; FO from the end of the exercise to the end of the session [in grams]: E70 = 45.7 +/- 8.9, E35 = 38.2 +/- 6.8, and Cont = 36.0 +/- 4.3). Blood parameters did not differ between the 3 sessions but changed according to the absorption of the nutrients. In overweight subjects, high-intensity exercise increased FO during the postexercise period even after food intake compared with the low-intensity exercise and the control session.

Abstract
BACKGROUND Eosinophil cationic protein (ECP) has been regarded as an excellent marker of eosinophil activation in various diseases where eosinophil-mediated inflammation plays a role. Recently, it has been suggested as a faecal marker of intestinal inflammation in several immune-mediated diseases with gastrointestinal expression. Owing to the scarcity of information at paediatric age, the establishment of reference values is necessary before further clinical studies. OBJECTIVE To determine faecal and serum ECP levels in healthy children and their association with other biological parameters, thereby providing background additional validation data for this age group. METHODS Faecal and serum ECP levels were available from healthy Caucasian children recruited at a regular outpatient clinic. Exclusion criteria were: chronic illnesses, acute illness, mucosal bleeding and recent pharmacological medication. Faecal and serum ECP levels and faecal a1AT were determined by commercial radioimmunoassay and serum IgE by fluoroenzyme immunoassay Uni-CAP. RESULTS Mean and median faecal ECP levels were 1.93 microg/g and 1.20 microg/g, respectively (range 0.41-22.20),while the corresponding serum ECP levels were 13.50 microg/L and 9.54 microg/L, respectively (range 0.20-74.8). The cut-offs found were 2.80 microg/g and 16.89 microg/L for faecal and serum ECP, respectively. A significant (p=0.001) increase in serum, but not in faecal, ECP levels was found among patients with high peripheral eosinophil blood count. Neither faecal nor serum ECP levels were influenced by serum IgE levels. CONCLUSIONS Faecal and serum ECP levels, as determined in the present study, add background information concerning reference levels at paediatric age for further studies indifferent clinical settings.

Abstract
In short bowel syndrome (SBS), although a remaining colon improves patient outcome, there is no direct evidence of a mucosal colonic adaptation in humans. This prospective study evaluates morphology, proliferation status, and transporter expression level in the epithelium of the remaining colon of adult patients compared with controls. The targeted transporters were Na+/H+ exchangers (NHE2 and 3) and oligopeptide transporter (PepT1). Twelve adult patients with a jejuno-colonic anastomosis were studied at least 2 yr after the last surgery and compared with 11 healthy controls. The depth of crypts and number of epithelial cells per crypt were quantified. The proliferating and apoptotic cell contents were evaluated by revealing Ki67, PCNA, and caspase-3. NHE2, NHE3, PepT1 mRNAs, and PepT1 protein were quantified by quantitative RT-PCR and Western blot, respectively. In patients with SBS compared with controls, 1) hyperphagia and severe malabsorption were documented, 2) crypt depth and number of cells per crypt were 35% and 22% higher, respectively (P < 0.005), whereas the proliferation and apoptotic levels per crypt were unchanged, and 3) NHE2 mRNA was unmodified; NHE3 mRNA was downregulated near the anastomosis and unmodified distally, and PepT1 mRNA and protein were unmodified. We concluded that, in hyperphagic patients with SBS with severe malabsorption, adaptive colonic changes include an increased absorptive surface with an unchanged proliferative/apoptotic ratio and well-preserved absorptive NHE2, NHE3, and PepT1 transporters. This is the first study showing a controlled nonpharmacological hyperplasia in the colon of patients with SBS.

Abstract
BACKGROUND & AIMS Tube feeding, recommended for patients with short bowel syndrome in only the postoperative period, has not been compared with oral feeding for absorption. We studied whether tube feeding increased absorption in patients with short bowel syndrome following the postoperative period. METHODS A randomized crossover study compared absorption between isocaloric tube feeding and oral feeding in 15 short bowel syndrome patients more than 3 months after short bowel constitution. An oral feeding period combined with enriched (1000 kcal * day(-1)) tube feeding was also tested. We measured the net intestinal absorption rates of proteins, lipids, and total calories using elemental nitrogen, Van de Kamer, and bomb calorimetry methods, respectively. RESULTS Tube feeding increased the mean (+/-SD) percent absorption (P < .001) of proteins (72% +/- 13% vs 57% +/- 18%), lipids (69% +/- 25% vs 41% +/- 27%), and energy (82% +/- 12% vs 65% +/- 16%) compared with oral feeding. In the group given the combined feedings (n = 9), the total enteral intake and net percent absorption increased (P < .001) for proteins (67% +/- 10%), lipids (59% +/- 19%), and total energy (75% +/- 8%) compared with oral feeding. Absorption (kcal * day(-1)) was greater (P < .001) with tube (2225 +/- 457) and combined feedings (2323 +/- 491) than with oral feeding (1638 +/- 458). CONCLUSIONS In patients with short bowel syndrome, continuous tube feeding (exclusively or in conjunction with oral feeding) following the postoperative period significantly increased net absorption of lipids, proteins, and energy compared with oral feeding.

Abstract
Defensins, endogenous antibiotic peptides, are part of the intestinal epithelial barrier. In this pilot study we analyzed the possibility of measuring fecal beta-defensin-2 (HBD2) in comparing inflammatory and noninflammatory conditions. In samples from healthy control individuals, low levels of HBD2 were detectable, which markedly rose under inflammatory conditions (P = 0.0002 vs normal control individuals), the highest levels being observed in patients with ulcerative colitis (median 356 ng/g, range 40-527). Despite frank inflammation, Crohn disease patients with colitis had significantly lower, albeit enhanced, HBD2 levels than did ulcerative colitis patients. These data confirm the possibility of quantifying HBD2 in feces and indicate that colitis in Crohn disease and colitis in ulcerative colitis differ from each other with respect to their ability to secrete HBD2.

Abstract
The intestinal epithelium is a selective barrier where incompletely-digested food antigens are transmitted to the immune system. Food antigens are often the starting point of intestinal diseases such as food allergy or coeliac disease. The intestinal epithelial cells (IEC) take up and process food antigens mainly by fluid-phase transcytosis involving two functional pathways, one minor direct pathway without degradation and another major lysosomal degradative pathway. Among the peptidic metabolites generated during transepithelial transport of luminal antigens, some have a molecular mass compatible with a binding to restriction (major histocompatibility complex; MHC) molecules; the latter can be up regulated on enterocytes, especially in inflammatory conditions. Indeed, interferon-γ not only increases the paracellular absorption of antigens, but also their transcytosis across epithelial cells. It has been reported that enterocytes may even directly present peptidic epitopes to underlying T-cells. As a new potential way of transmitting peptidic information to the local or systemic immune system, the secretion by IEC of antigen-presenting vesicles called exosomes and bearing MHC–peptide complexes has recently been proposed. Many other factors such as nutritional or environmental factors can also influence the properties of the epithelial barrier and the outcome of the immune response to lumen antigens.

Abstract
SCOPE The eosinophil cationic protein (ECP) is one of the mediators released during eosinophil activation. These cells are effector cells taking part into the Th2-lymphocyte dependent allergic inflammation. Assaying ECP concentrations in blood and sputum may be useful in evaluating allergic inflammation (asthma and rhinitis). This summary considers the value of measuring ECP levels for the diagnosis of various diseases where an eosinophil-mediated tissue inflammation plays a role. CURRENT SITUATION AND SALIENT POINTS Levels of eosinophil cationic protein have been determined in nasal secretions, sputum, gastric secretions, feces and serum. They are increased during seasonal allergic rhinitis and perennial rhinitis, allergic asthma and atopic dermatitis. They are also increased in various gastro-intestinal disorders, some of which are associated with IgE: eosinophil intestinal diseases (esophagitis, gastro-enteritis and colitis), gastro-intestinal food allergy and intestinal parasitoses. Finally, they are increased in non IgE-dependent disorders: non allergic asthma with aspirin intolerance, respiratory infections, sinonasal polyposis, Churg-Strauss disease and idiopathic hyper-eosinophilia (HES) syndrome. PERSPECTIVES Assaying serum ECP could help in the diagnosis of several diseases. With parasitic disease the pathogenic progression may be accurately assessed, when serological tests are less indicative. ECP assay may point to non allergic asthma, either Fernand-Widal syndrome or Churg-Strauss disease. As for gastro-intestinal disorders, it indicates an eosinophilic tissue reaction. In the event of isolated hypereosinophilia, ECP assay may clarify whether it is benign or tending towards idiopathic HES. The assay of peroxidase and eosinophil-derived neurotoxin (EDN) should be also considered.

Abstract
OBJECTIVE The etiology of early-onset diarrhea of neonates and small infants that persists despite bowel rest is heterogeneous. Two different categories of disorders presenting with diarrhea in the first weeks of life can be distinguished: constitutive intestinal epithelial disorders (microvillus atrophy [MVA] or epithelial dysplasia [ED]) and immune-inflammatory disorders, (autoimmune enteropathy [AIE] or inflammatory colitis [IC]). We aimed to evaluate in a prospective manner the use of fecal inflammatory markers in the differential diagnosis of severe persistent diarrhea. MATERIAL AND PATIENTS Twenty-five patients (17 males) were enrolled in this study (median age 8 months). Fourteen children had a constitutive enterocyte disorder (group 1: MVA = 8, ED = 6), and 11 patients had an immuno-inflammatory disease (group 2: AIE = 5, IC = 6). Stool samples were collected at the time of diagnosis and stored at -80 degrees until tumor necrosis factor (TNF)-alpha and calprotectin were measured by enzyme-linked immunoadsorbent assay. RESULTS No significant differences in age at onset of diarrhea or in stool volumes were observed between both groups. In group 1, fecal TNF-alpha was undetectable/normal in 14 of 14 children, whereas group 2 showed dramatically elevated TNF-alpha levels (mean 3,104, range 237-18,078 pg/g) in 8 of 11 patients. Similarly, calprotectin levels were undetectable/normal in 14 of 14 patients in group 1 and highly raised in 11 of 11 patients in group 2 (median 1,145, range 375-3,095 mug/g), P < 0.01. Under therapy, these inflammatory parameters normalized. CONCLUSIONS Determination of fecal inflammatory markers is a simple method helping to distinguish constitutive from immuno-inflammatory etiologies of severe persistent diarrhea. These data also suggest that constitutive enterocyte disorders are not accompanied by an inflammatory mucosal reaction.

Abstract
Adverse reactions to food that result in gastrointestinal symptoms are common in the general population; while only a minority of such individuals will have symptoms due to immunologic reactions to foods, gastrointestinal food allergies do exist in both children and adults. These immune reactions are mediated by immunoglobulin E-dependent and -independent mechanisms involving mast cells, eosinophils, and other immune cells, but the complexity of the underlying mechanisms of pathogenesis have yet to be fully defined. Knowledge of the spectrum of adverse reactions to foods that affect the digestive system, including gastrointestinal food allergy, is essential to correctly diagnose and manage the subset of patients with immunologically mediated adverse reactions to foods. Potentially fatal reactions to food necessitate careful instruction and monitoring on the part of health care workers involved in the care of individuals at risk of anaphylaxis. New methods of diagnosis and novel strategies for treatment, including immunologic modulation and the development of hypoallergenic foods, are exciting developments in the field of food allergy.

Abstract
Probiotic bacteria are proposed to alleviate intestinal inflammation in infants with atopic eczema/dermatitis syndrome (AEDS) and food allergy. In such infants we investigated effects of probiotic bacteria on faecal IgA, and on the intestinal inflammation markers tumour necrosis factor-alpha (TNF-alpha), alpha1-antitrypsin (AT), and eosinophil cationic protein (ECP). A total of 230 infants with AEDS and suspected cow's milk allergy (CMA) received in a randomized double-blinded manner, concomitant with elimination diet, Lactobacillus GG (LGG), a mixture of four probiotic strains (MIX), or placebo for 4 wk. Four weeks after treatment, CMA was diagnosed with a double-blind placebo-controlled milk challenge. Faecal samples of 102 infants, randomly chosen for analysis, were collected before treatment, after 4-wk treatment, and on the first day of milk challenge. After treatment, IgA levels tended to be higher in probiotic groups than in the placebo group (LGG vs. placebo, p=0.064; MIX vs. placebo, p=0.064), and AT decreased in the LGG group, but not in other treatment groups. After challenge in IgE-associated CMA infants, faecal IgA was higher for LGG than for placebo (p=0.014), and TNF-alpha was lower for LGG than for placebo, but non-significantly (p=0.111). In conclusion, 4-wk treatment with LGG may alleviate intestinal inflammation in infants with AEDS and CMA.

Abstract
BACKGROUND The role of TNF-alpha in Crohn disease is now well established and anti-TNF-alpha is frequently used as a second- or third-line treatment. Tumor necrosis factor-alpha (TNF-alpha) is traditionally associated with macrophages but has recently also been found in mast cells of the ileal wall in patients with Crohn disease. As it is well known that mast cells and TNF-alpha play important roles in atopic manifestations like asthma, allergic rhinitis; and eczema the aim of this study was to investigate whether these are seen more commonly in Crohn patients than in the general population. METHODS Patients with Crohn disease (n = 308), aged 18-50 years, living in the Linköping region in southeast Sweden, were asked to answer a questionnaire regarding the presence of any kind of atopic manifestations. The questionnaire was also sent to 930 controls collected from the Southeastern Region Population Registry. The controls were matched according to age, sex, and place of residence. RESULTS The response rate among the Crohn patients was 91% (280/308) and among controls 84% (779/930). Eczema was a significantly more frequent manifestation, being almost twice as common in Crohn patients (27%) as in the general population (16%). Adjustment by logistic regression for place of residence, gender, age and coexistence of any other atopic manifestation did not change the odds ratios significantly. CONCLUSION Atopic manifestations as a group, and eczema as a single manifestation, are significantly more frequent in Crohn patients than in the general population.

Abstract
PURPOSE OF REVIEW Adverse reactions to food resulting in gastrointestinal symptoms are common in the general population. Although only a minority of individuals complaining of such symptoms have immune-mediated reactions to food (food allergy), gastrointestinal food allergies do exist in both children and adults. This review provides an update on the pathogenesis and clinical management of food allergy manifesting in the gut, emphasizing recent developments in the field. RECENT FINDINGS Recent studies have broadened our understanding of the innate gastrointestinal defense systems and the role of the gut flora for protection against allergy. These findings support the hygiene theory in which microbial challenge in early life is thought to protect against the development of allergic disease. New insights into the regulation of mast cells and eosinophils, their homing to the intestine, and their interaction with the specific immune system and the enteric nervous system have been given. In parallel, the molecular structure of major food allergens is being unraveled, and new therapies that focus largely on modulating the immune response to food antigens have been developed. SUMMARY These new findings have important implications for the diagnosis and management of food allergies. The availability of recombinant allergens will improve methods to diagnose and treat food allergy, and genetic engineering will allow future therapies such as vaccination against food allergy. Emerging knowledge of the role of the gut flora in mucosal immunity will enhance strategies to prevent and treat food allergy using probiotics such as Lactobacillus GG. Such new approaches will extend existing options for managing food allergy and preventing anaphylaxis.

Abstract
Eosinophil infiltration into the gastrointestinal tract occurs in a wide range of diseases. However, the underlying cellular and molecular mechanisms involved in eosinophil migration and the role of eosinophils in disease pathogenesis are largely unknown. Recent studies using experimental models of eosinophil-associated gastrointestinal allergy have revealed differential roles for IL-5 and eotaxin in the modulation of eosinophil accumulation into various regions of the gastrointestinal tract. Furthermore, such studies have revealed a possible role for eosinophils in the pathogenesis of gastrointestinal disorders. The present review describes the clinical manifestations of various eosinophil-associated gastrointestinal disorders and the current understanding of the role of IL-5 and eotaxin in the allergic inflammatory response, and the participation of the eosinophilic granulocyte in the expression of disease.

Abstract
BACKGROUND In the pathogenesis of cow's milk allergy, abnormal immunologically mediated reactions play a basic role. Eosinophil activation also participates in the development of several allergies. The purpose of this study was to characterize the degree of this activation by measuring the serum level of eosinophil cationic protein (sECP) and establishing whether it is a useful parameter in monitoring oral cow's milk allergy. METHODS The sECP level of 35 patients with previously confirmed cow's milk allergy (mean age, 16 months) was evaluated using a fluoroimmunoassay before the cow's milk rechallenge test and at 2 hours and 24 hours after cow's milk challenge. RESULTS Of the 35 children with previously confirmed cow's milk allergy, 10 had positive clinical reactions after the milk rechallenge test, whereas 25 children had no reaction. The median sECP level of all the patients before the challenge test was significantly higher (12.4 microg/L) than that of the control group (4.3 microg/L) (P < 0.05). Two hours after the challenge, the median sECP of all patients (9.4 microg/L) was lower than the starting values. The median sECP levels were higher in children with positive challenge test results at all time points. However, this difference was not statistically significant. CONCLUSIONS The normalization of sECP level may indicate the cessation of the cow's milk allergy. Therefore, the measurement of sECP may be helpful in determining the optimal time in which to repeat the challenge test, when the result will more likely be negative. The significant decrease of the sECP level 2 hours after the beginning of milk challenge test may be explained by the fact that this protein is excreted into the intestinal lumen.

Abstract
The expression of food protein allergy in man is very heterogeneous, varies with the age of the subject and is to a certain extent genetically determined. Skin prick tests with standardized food extracts are a sensitive method for detection of immunoglobulin E bound to reactive cells such as mast cells. Various tests on cellular immunity have been developed, especially because T-cell mediated reactions are considered to play a role in mainly delayed gastrointestinal reactions to cow's milk proteins. Food allergy may involve the entire gut, from mouth to rectum, including the esophagus. Abnormalities in intestinal permeability are the hallmarks of the inflamed gut, and may contribute to diagnosis of food induced enteropathy. What determines the characteristics of the intestinal inflammatory response is largely the cytokine responses triggered by the pathologic mechanism, whatever its origin, in the stomach, the small intestine, and the colon. A so-called T-helper type 2 response is characteristic of the allergic subject. A secretion of tumor necrosis factor-alpha alpha by blood cells of children allergic to milk was shown. All means of investigation may help in analyzing food substitutes for allergic infants.
