Patients' and caregivers' perspective on challenges and outcomes with tube feeding: Analysis of home enteral nutrition survey data. Clin Nutr ESPEN 2024; 61:94-100. [PMID: 38777479 DOI: 10.1016/j.clnesp.2024.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 02/06/2024] [Accepted: 03/02/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND Given the growing use of home enteral nutrition (HEN), assessing the experience of consumers and caregivers is crucial to understanding the real-world subjective and objective challenges of administering HEN. METHODS After obtaining institutional review board approval, a survey was distributed to HEN consumers and caregivers between January 16, 2020, and July 16, 2021. Data collected included information regarding demographics, primary diagnosis, tube and connectors, HEN regimen, and overall HEN experience. RESULTS A total of 884 individuals responded to the survey: 673 (76.1%) responses by caregivers and 211 (23.9%) responses by patients. The study cohort included 566 (64%) children and 318 (36%) adults. The leading primary diagnosis of participants was developmental delay and motility disorder for children and adults, respectively. Low-profile gastric tubes were the most used (75.7% of children and 30.3% of adults). Notably, legacy connectors were utilized for more patients (46.7% children, 52.6% adults) compared to ISO-80369-3 connectors (38.9% children, 29.7% adults). HEN complications were prevalent, including enteral tube site infections and other tube-related complications, including clogging and kinking. CONCLUSION This real-world data reveals that HEN complications remain prevalent. Additionally, despite introducing ISO-80369-3 connectors many years ago, most patients continue to use legacy tubes with a significant lack of knowledge about ISO-80369-3 connectors. The survey results guide HEN providers to focus on several areas to reduce complications.

Experience and opinions relating to pregnancy in patients with chronic intestinal failure: an international survey. Frontline Gastroenterol 2023; 14:377-383. [PMID: 37581192 PMCID: PMC10423604 DOI: 10.1136/flgastro-2023-102384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 03/09/2023] [Indexed: 08/16/2023] Open
Abstract
Introduction Pregnancy in patients with chronic intestinal failure (CIF) is a relatively rare occurrence but is an important contemporary topic given both the increasing use of home parenteral nutrition (HPN) and the demographics of patients with CIF. Method An opinion-based survey was produced in a multidisciplinary manner, which was then distributed internationally, via the European Society for Clinical Nutrition and Metabolism network, using a web-based survey tool for healthcare professionals with a specialist interest in the management of CIF. Results Seventy specialists from 11 countries completed the survey. Fifty-four per cent of the respondents reported some experience of managing pregnancy in patients with CIF. However, 60% stated that they did not feel that it was their role to discuss the topic of pregnancy with their patients, with fewer than 10% stating that they routinely did so. Respondents felt that an individualised approach was required when considering alterations to parenteral support prior to conception, during pregnancy and in the postnatal period. Most respondents also felt there was no increased risk of catheter-related blood stream infections, while catheter-related thrombosis was deemed to be the most significant HPN-related complication for pregnant women. Conclusion This study reports a variable experience, knowledge and confidence of healthcare professionals when considering pregnancy in patients with CIF. The risk of HPN-related complication was felt to be greater during pregnancy, with an individualised approach being the preferred route for most aspects of care. The findings support the need for an international registry and subsequent consensus guidelines for the management of pregnancy in CIF.

Abstract
This guideline will inform physicians, nurses, dieticians, pharmacists, caregivers and other home parenteral nutrition (HPN) providers, as well as healthcare administrators and policy makers, about appropriate and safe HPN provision. This guideline will also inform patients requiring HPN. The guideline is based on previous published guidelines and provides an update of current evidence and expert opinion; it consists of 71 recommendations that address the indications for HPN, central venous access device (CVAD) and infusion pump, infusion catheter and CVAD site care, nutritional admixtures, program monitoring and management. Meta-analyses, systematic reviews and single clinical trials based on clinical questions were searched according to the PICO format. The evidence was evaluated and used to develop clinical recommendations implementing Scottish Intercollegiate Guidelines Network methodology. The guideline was commissioned and financially supported by ESPEN and members of the guideline group were selected by ESPEN.

Considerations for the management of home parenteral nutrition during the SARS-CoV-2 pandemic: A position paper from the Home Artificial Nutrition and Chronic Intestinal Failure Special Interest Group of ESPEN. Clin Nutr 2020; 39:1988-1991. [PMID: 32487434 PMCID: PMC7253968 DOI: 10.1016/j.clnu.2020.05.023] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 05/15/2020] [Accepted: 05/18/2020] [Indexed: 12/29/2022]
Abstract
The management of patients with chronic intestinal failure requiring home parenteral nutrition has been and will continue to be impaired during the SARS-CoV-2 pandemic. Multidisciplinary intestinal failure teams may have to adapt their clinical approaches to home care, outpatient care as well as hospital admission and discharge in order to keep this vulnerable group of patients as safe and well as possible during the unprecedented challenges that countries are facing during the pandemic. Equally, it is important that expert advice from intestinal failure teams is available when home parenteral nutrition (HPN)-dependent patients require admission with SARS-CoV-2 infection. The Home Artificial Nutrition & Chronic Intestinal Failure Special Interest Group of the European Society for Clinical Nutrition and Metabolism (ESPEN) has developed a position paper to outline areas for intestinal failure teams to consider when managing patients with chronic intestinal failure during the SARS-CoV-2 pandemic.

Abstract
BACKGROUND & AIMS Intestinal failure (IF) is defined as "the reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that intravenous supplementation is required to maintain health and/or growth". Functionally, it may be classified as type I acute intestinal failure (AIF), type II prolonged AIF and type III chronic intestinal failure (CIF) The ESPEN Workshop on IF was held in Bologna, Italy, on 15-16 October 2017 and the aims of this document were to highlight the current state of the art and future directions for research in IF. METHODS This paper represents the opinion of experts in the field, based on current evidence. It is not a formal review, but encompasses the current evidence, with emphasis on epidemiology, classification, diagnosis and management. RESULTS IF is the rarest form of organ failure and can result from a variety of conditions that affect gastrointestinal anatomy and function adversely. Assessment, diagnosis, and short and long-term management involves a multidisciplinary team with diverse expertise in the field that aims to reduce complications, increase life expectancy and improve quality of life in patients. CONCLUSIONS Both AIF and CIF are relatively rare conditions and most of the published work presents evidence from small, single-centre studies. Much remains to be investigated to improve the diagnosis and management of IF and future studies should rely on multidisciplinary, multicentre and multinational collaborations that gather data from large cohorts of patients. Emphasis should also be placed on partnership with patients, carers and government agencies in order to improve the quality of research that focuses on patient-centred outcomes that will help to improve both outcomes and quality of life in patients with this devastating condition.

Abstract
RATIONALE This initiative is focused on building a global consensus around core diagnostic criteria for malnutrition in adults in clinical settings. METHODS In January 2016, the Global Leadership Initiative on Malnutrition (GLIM) was convened by several of the major global clinical nutrition societies. GLIM appointed a core leadership committee and a supporting working group with representatives bringing additional global diversity and expertise. Empirical consensus was reached through a series of face-to-face meetings, telephone conferences, and e-mail communications. RESULTS A two-step approach for the malnutrition diagnosis was selected, i.e., first screening to identify "at risk" status by the use of any validated screening tool, and second, assessment for diagnosis and grading the severity of malnutrition. The malnutrition criteria for consideration were retrieved from existing approaches for screening and assessment. Potential criteria were subjected to a ballot among the GLIM core and supporting working group members. The top five ranked criteria included three phenotypic criteria (non-volitional weight loss, low body mass index, and reduced muscle mass) and two etiologic criteria (reduced food intake or assimilation, and inflammation or disease burden). To diagnose malnutrition at least one phenotypic criterion and one etiologic criterion should be present. Phenotypic metrics for grading severity as Stage 1 (moderate) and Stage 2 (severe) malnutrition are proposed. It is recommended that the etiologic criteria be used to guide intervention and anticipated outcomes. The recommended approach supports classification of malnutrition into four etiology-related diagnosis categories. CONCLUSION A consensus scheme for diagnosing malnutrition in adults in clinical settings on a global scale is proposed. Next steps are to secure further collaboration and endorsements from leading nutrition professional societies, to identify overlaps with syndromes like cachexia and sarcopenia, and to promote dissemination, validation studies, and feedback. The diagnostic construct should be re-considered every 3-5 years.

Clinical approach to the management of Intestinal Failure Associated Liver Disease (IFALD) in adults: A position paper from the Home Artificial Nutrition and Chronic Intestinal Failure Special Interest Group of ESPEN. Clin Nutr 2018; 37:1794-1797. [PMID: 30017241 DOI: 10.1016/j.clnu.2018.07.006] [Citation(s) in RCA: 70] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Accepted: 07/03/2018] [Indexed: 12/30/2022]
Abstract
We recommend that intestinal failure associated liver disease (IFALD) should be diagnosed by the presence of abnormal liver function tests and/or evidence of radiological and/or histological liver abnormalities occurring in an individual with IF, in the absence of another primary parenchymal liver pathology (e.g. viral or autoimmune hepatitis), other hepatotoxic factors (e.g. alcohol/medication) or biliary obstruction. The presence or absence of sepsis should be noted, along with the duration of PN administration. Abnormal liver histology is not mandatory for a diagnosis of IFALD and the decision to perform a liver biopsy should be made on a case-by-case basis, but should be particularly considered in those with a persistent abnormal conjugated bilirubin in the absence of intra or extra-hepatic cholestasis on radiological imaging and/or persistent or worsening hyperbilirubinaemia despite resolution of any underlying sepsis and/or any clinical or radiological features of chronic liver disease. Nutritional approaches aimed at minimising PN overfeeding and optimising oral/enteral nutrition should be instituted to prevent and/or manage IFALD. We further recommend that the lipid administered is limited to less than 1 g/kg/day, and the prescribed omega-6/omega-3 PUFA ratio is reduced wherever possible. For patients with any evidence of progressive hepatic fibrosis or overt liver failure, combined intestinal and liver transplantation should be considered.

Analysis of Genes Associated With Monogenic Primary Immunodeficiency Identifies Rare Variants in XIAP in Patients With Crohn's Disease. Gastroenterology 2018; 154:2165-2177.

Abstract
BACKGROUND & AIMS A few rare monogenic primary immunodeficiencies (PIDs) are characterized by chronic intestinal inflammation that resembles Crohn's disease (CD). We investigated whether 23 genes associated with 10 of these monogenic disorders contain common, low-frequency, or rare variants that increase risk for CD. METHODS Common and low frequency variants in 1 Mb loci centered on the candidate genes were analyzed using meta-data corresponding to genotypes of approximately 17,000 patients with CD or without CD (controls) in Europe. The contribution of rare variants was assessed by high-throughput sequencing of 4750 individuals, including 660 early-onset and/or familial cases among the 2390 patients with CD. Variants were expressed from vectors in SW480 or HeLa cells and functions of their products were analyzed in immunofluorescence, luciferase, immunoprecipitation, and immunoblot assays. RESULTS We reproduced the association of the interleukin 10 locus with CD (P = .007), although none of the significantly associated variants modified the coding sequence of interleukin 10. We found XIAP to be significantly enriched for rare coding mutations in patients with CD vs controls (P = .02). We identified 4 previously unreported missense variants associated with CD. Variants in XIAP cause the PID X-linked lymphoproliferative disease type 2, yet none of the carriers of these variants had all the clinical features of X-linked lymphoproliferative disease type 2. Identified XIAP variants S123N, R233Q, and P257A were associated with an impaired activation of NOD2 signaling after muramyl dipeptide stimulation. CONCLUSIONS In a systematic analysis of variants in 23 PID-associated genes, we confirmed the association of variants in XIAP with CD. Further screenings for CD-associated variants and analyses of their functions could increase our understanding of the relationship between PID-associated genes and CD pathogenesis.

Abstract
The prevalence of overweight and obesity has reached epidemic proportions worldwide due to increasingly pervasive obesogenic lifestyle changes. Obesity poses unprecedented individual, social and multi-disciplinary medical challenges by increasing the risk for metabolic diseases, chronic organ failures and cancer, as well as complication rates in the presence of acute disease conditions. Whereas reducing excess adiposity remains the fundamental pathogenetic treatment for obese individuals, complex metabolic and lifestyle abnormalities as well as weight-reduction therapies per se may also compromise the ability to preserve muscle function and mass, especially when chronic disease co-exists with obesity. Emerging evidence indicates that low muscle mass and quality have a strong negative prognostic impact in obese individuals and may lead to frailty, disability and increased morbidity and mortality. Awareness of the importance of skeletal muscle maintenance in obesity is however low among clinicians and scientists. The term "sarcopenic obesity" has been proposed to identify obesity with low skeletal muscle function and mass, but its utilization is largely limited to the aging patient population, and consensus on its definition and diagnostic criteria remains insufficient. Knowledge on prevalence of sarcopenic obesity in various clinical conditions and patient subgroups, on its clinical impacts in patient risk stratification and on effective prevention and treatment strategies remain therefore dramatically inadequate. In particular, optimal dietary options and medical nutritional support strategies to preserve muscle mass in obese individuals remain largely undefined. The European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO) recognize and indicate obesity with altered body composition due to low skeletal muscle function and mass (sarcopenic obesity) as a scientific and clinical priority for researchers and clinicians. ESPEN and EASO therefore call for coordinated action aimed at reaching consensus on its definition, diagnostic criteria and optimal treatment with particular regard to nutritional therapy. We are convinced that achievement of these goals has strong potential to reduce the burden of morbidity and mortality in the rapidly increasing obese patient population.

Abstract
BACKGROUND AND AIMS Progressive multifocal leukoencephalopathy [PML], a brain infection associated with anti-integrin drugs that inhibit lymphocyte translocation from bloodstream to tissue, can be fatal. Decreased central nervous system [CNS] immune surveillance leading to this infection has been reported in patients with multiple sclerosis or Crohn's disease treated with anti-integrin antibody natalizumab. PF-00547659 is an investigational human monoclonal antibody for inflammatory bowel disease, targeted against α4β7-mucosal addressin cell-adhesion molecule-1 [the integrin ligand selectively expressed in the gut]. We hypothesised that this selective agent would not affect central nervous system immune surveillance. METHODS Cerebrospinal fluid from five healthy volunteers, and from 10 patients with Crohn's disease previously treated with immunosuppressants, was evaluated to assess the feasibility of the study. Subsequently, 39 patients with active Crohn's disease and previous immunosuppression were evaluated over 12 weeks of PF-00547659-induction therapy. We measured total lymphocytes, T cell subsets in cerebrospinal fluid, and circulating β7+ memory cells. Disease activity was assessed using the Harvey-Bradshaw Index. RESULTS Patients treated with PF-00547659 had no reduction of cerebrospinal fluid lymphocytes, T-lymphocyte subsets, or CD4:CD8 ratio, whereas circulating β7+ memory cells increased significantly. A total of 28/35 [80%] patients had a clinical response and 27/34 [79%] had disease remission. Treatment-related adverse events, none serious, were reported in 23/49 [47%] patients. CONCLUSIONS In patients with active Crohn's disease, natalizumab therapy increases the risk for PML, and the increased risk is thought to be associated with iatrogenic leukopenia within the CNS. PML under PF-00547659 may be a lesser concern, as this agent did not reduce lymphocytes or T cell subsets in the cerebrospinal fluid.

Abstract
Abstract
Background
Blocking integrins can be associated with an increased risk of progressive multifocal encephalopathy (PML). MAdCAM-1 is an adhesion molecule that is not constitutively expressed in healthy CNS and considered mostly gut-selective. However, MAdCAM-1 is upregulated in choroid plexus epithelium during experimental autoimmune encephalomyelitis (EAE. PF-00547659 is a fully human mAb that is highly selective for MAdCAM-1. The purpose of this study was to investigate its effect on cellular elements of immune surveillance in the CNS and blood of patients with Crohn’s disease (CD).
Methods
All methods were tested in a control cohort of volunteers with CD (Cohort 1). Study patients (Cohort 2) had CD and prior treatment with anti-TNF and immunosuppressant therapies. Patients underwent a lumbar puncture (LP1) followed by 3 monthly injections of 225 mg PF-00547659. After the last dose, a LP2 was performed. CSF was analyzed within 24h by multi-parameter flow cytometry.
Results
In Cohort 1, the lymphocyte subset percentages were the same at both time points. Cohort 2 consisted of 30 patients in whom 2 LPs were performed. Their pre-treatment lymphocyte numbers were lower than those of subjects who had stopped immunosuppressants, but otherwise results were the same. CSF lymphocytes (cells per mL) shown as geometric means (CV%). LP1: 37 patients, total lymphocytes 391 (140%), CD3+/CD4+ cells 246 (152%), CD3+/CD8+ cells 100 (126%), CD4:CD8 ratio 2.46 (57%). LP2: 30 patients, total lymphocytes 513 (137%), CD3+/CD4+ cells 332 (143%), CD3+/CD8+ cells 123 (125%), CD4:CD8 ratio 2.69 (56%).
Conclusion
This is the first evidence that a therapeutic dose of anti-MAdCAM-1 mAb does not affect the number and composition of leukocytes in the CNS.

Abstract
Video capsule endoscopy (VCE) was launched in 2000 and has revolutionized direct endoscopic imaging of the gut. VCE is now a first-line procedure for exploring the small bowel in cases of obscure digestive bleeding and is also indicated in some patients with Crohn’s disease, celiac disease, and polyposis syndrome. A video capsule has also been designed for visualizing the esophagus in order to detect Barrett’s esophagus or esophageal varices. Different capsules are now available and differ with regard to dimensions, image acquisition rate, battery life, field of view, and possible optical enhancements. More recently, the use of VCE has been extended to exploring the colon. Within the last 5 years, tremendous developments have been made toward increasing the capabilities of the colon capsule. Although colon capsule cannot be proposed as a first-line colorectal cancer screening procedure, colon capsule may be used in patients with incomplete colonoscopy or in patients who are unwilling to undergo colonoscopy. In the near future, new technological developments will improve the diagnostic yield of VCE and broaden its therapeutic capabilities.

Abstract
AIM To describe a poorly known endoscopic entity associated with portal hypertension, characterized by polypoid lesions either in the stomach or small intestine of patients with cirrhosis. METHODS Between 2003 and 2012, patients with cirrhosis and portal hypertension underwent endoscopic workup of portal hypertension in our endoscopy unit. The clinical expression, endoscopic features of these lesions, and their pathological characteristics are described. RESULTS A total of 1538 patients were included, among which 14 (0.9%) presented polypoid lesions; these patients had evidence of portal hypertension and had dilated capillaries in the lamina propria. Four patients presented with severe anaemia or melaena and required treatment. Propranolol was administered to three patients, and one patient needed a transjugular intrahepatic portosystemic shunt in order to control bleeding. For asymptomatic patients in whom polypoid lesions were resected, no recurrence of lesions was observed during follow-up gastroscopy (median 36 months, range 7-85 months). CONCLUSION Portal hypertension-associated gastric or small intestine polypoid lesions may be associated with a significant risk of bleeding and are responsive to adequate treatment of portal hypertension.

Abstract
BACKGROUND Seventy percent of Crohn's disease (CD) patients exhibit anastomotic recurrence within 1 year after ileo-caecal surgery. Recent clinical trials suggest the beneficial use of probiotics in the control of intestinal inflammation in pouchitis and ulcerative colitis. This study is a multicenter clinical trial evaluating the efficacy of an oral administration of the probiotic LAl on early post-operative endoscopic recurrence of CD. METHODS Seventy patients with CD were enrolled prior to elective ileo-caecal resection and randomly assigned after surgery to daily treatment with either Lactobacillus johnsonii, LA1, Nestle (1010 colony-forming units, CFU) (group A, n = 34) or placebo (group B, n = 36) for 12 weeks. The primary objective was to assess the effect of LAl on the endoscopic recurrence rate at 12 weeks. Stratification was performed according to smoking status at randomization. RESULTS Seven and 14 patients were excluded in the LA1 and placebo groups, respectively. In intention-to-treat analysis, the mean endoscopic score was not significantly different between the two treatment groups at 3 months (LA1 versus placebo: 1.50 +/- 1.32 versus 1.22+/-1.37, treatment effect: P = 0.48, smoke effect: P = 0.72). The percentage of patients with severe recurrence (i3 + i4) was 21% and 15% in the LAl and placebo groups, respectively (P = 0.33). Using a per-protocol (PP) analysis, the mean endoscopic score was not significantly different between the two treatment groups (LAl versus placebo groups: 1.44 +/-1.31 versus 1.05 +/- 1.21, P = 0.32). The percentage of patients with severe recurrence (i3 + i4) was 19% and 9% in the LAl and placebo groups, respectively (P = 0.054). Clinical relapse rate (CDAI [CD activity index] > 150, with an increase of CDAI > 70 points or greater from baseline) in the LAl and placebo groups was 15% (4/27) and 13.5% (3/22), respectively (PP analysis: chi-square test, P = 0.91 and log-rank test: P = 0.79). CONCLUSION Oral administration of the probiotic LA1 in patients with CD failed to prevent early endoscopic recurrence at 12 weeks after ileo-caecal resection.

Monitoring of patients on home parenteral nutrition (HPN) in Europe: A questionnaire based study on monitoring practice in 42 centres. Clin Nutr 2006; 25:693-700. [PMID: 16698149 DOI: 10.1016/j.clnu.2006.01.026] [Citation(s) in RCA: 28] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2005] [Revised: 12/14/2005] [Accepted: 01/17/2006] [Indexed: 11/25/2022]
Abstract
INTRODUCTION & AIM To gather information about how adult patients on home parenteral nutrition (HPN) are monitored after discharge from the hospital. METHOD A questionnaire about HPN monitoring practice was circulated to HPN centres in eight European countries through the representative of the ESPEN HAN-working group. Centres were asked about guidelines, home visits and how monitoring and handling of complications were managed. RESULTS Fourty-two centres in eight European countries completed the questionnaire: UK n=14, France n=9, Belgium n=4, Italy n=4, Poland n=4, Denmark n=4, Spain n=2, Germany n=1. The HPN experience of the centres was in the range 2-30 years. Centres ranged in size from 0 to 125 HPN patients representing a total number of 934 of whom 54% had received HPN for more than 2 years. The primary disease was non-malignant in 90% whilst 10% had been diagnosed with active cancer. Of the centres 92% had a HPN team and 66% had written guidelines for monitoring HPN. Home visits after discharge for monitoring purposes were carried out by 31 of the centres involving the HPN team, general practitioner, community nurse or home care agency. Stable patients on HPN for more than 12 months were monitored at the discharging hospital (73%), at a local hospital (12%), by the General Practitioner (11%) or by a home care agency (4%). Of the centres, 90% reported that the main responsibility for monitoring was assigned to a specific person. The intervals between monitoring visits for the stable HPN patient was in the range 1-6 months, 52% of the centres reported intervals of 2-3 months. In case of complications 76% of centres reported that patients got in touch with the HPN team, 2% the local hospital, 5% the home care agency, and 17% other. Re-admission to hospital was usually to the HPN centre and only occasionally to a local hospital. CONCLUSION In Europe a specialised team at the discharging hospital monitors HPN patients and 66% of the centres had some kind of written guidelines.

Abstract
OBJECTIVES Epidemiology of candidacy for intestinal transplantation (ITx) and timing for referral for ITx are unknown. Patient candidacy and physician attitudes toward ITx were investigated among centers that participated in previous European surveys on home parenteral nutrition (HPN). METHODS Patients on HPN for benign intestinal failure (IF) were evaluated by a structured questionnaire. Candidacy was assessed by USA Medicare and American Transplantation Society criteria, categorized as: (1) life-threatening HPN complications; (2) high risk of death because of the gastrointestinal disease; (3) IF with high morbidity or patient HPN refusal. Physicians judged candidacy as immediate or potential. RESULTS Forty-one centers from nine countries enrolled 688 adults (> 18 yr) and 166 pediatric patients; 70% of patients were from five countries which collected 60-100% of their HPN patients. Candidacy was 15.7% in adults and 34.3% in pediatrics (HPN failure, 62.1% and 28.1%; gastrointestinal disease, 25.9% and 59.6%; high morbidity IF or HPN refusal, 12.0% and 12.3%, respectively). Immediate candidacy was required for 14.8% of adult and 15.8% of pediatric candidates (< 50% of candidates because of HPN-related liver failure). Among centers, the candidacy rate ranged 0-100% and was negatively associated with the number of patients enrolled in the survey (R = -0.463, p = 0.002). Among the major contributing countries, candidacy ranged 0.3-0.8/million inhabitants for adults and 0.9-2/million inhabitants < or = 18 yr for pediatric candidates. CONCLUSIONS The rate of candidacy and the indications for ITx candidacy differed greatly among age groups and HPN centers; within countries candidacy was more homogeneous; physicians had a generally reserved attitude toward ITx.

Abstract
OBJECTIVES In mice, body weight is regulated by adipocyte-derived leptin. TNFalpha is a critical mediator of inflammation-induced cachexia in Crohn's disease (CD). The regulation of leptin by TNFalpha is poorly understood in CD. Pharmacological neutralization of TNFalpha with infliximab offers a unique opportunity to study TNFalpha-mediated regulation of leptin in CD patients. METHODS We prospectively followed up CD patients treated with infliximab (n = 20). Body composition was assessed before and after treatment at 1 and 4 wk. Serum leptin, IL-6, soluble TNF receptor type II, and soluble intercellular antiadhesion molecule-1 levels were measured as well as cholesterol levels and free urinary cortisol. Because methylprednisolone (MP) increases leptin production in vivo, CD patients treated with MP (n = 9) were studied separately as a positive control group. RESULTS Infliximab induced clinical remission and a significant decrease in C-reactive protein (P < 0.01) and IL-6 (P < 0.05) levels in all CD patients and increased body weight (P = 0.013) at 4 wk. Leptinemia was significantly increased after infliximab administration at 1 wk (P = 0.014) and 4 wk (P < 0.001). This increase in serum leptin occurred early at 1 wk, when no significant weight and fat mass changes could be observed and was associated with the down-regulation of TNFalpha-regulated mediators, soluble TNF receptor type II (P = 0.015), and soluble intercellular antiadhesion molecule-1 (P = 0.007). Moreover, infliximab increased cholesterol levels at 1 wk (P = 0.001). Twenty-four-hour cortisol secretion was not altered by infliximab. Leptinemia increased at 1 wk after MP administration (P = 0.028). CONCLUSION Infliximab increases leptinemia in CD. This study suggests that TNFalpha exerts major inhibitory actions on leptin production in CD patients.

Abstract
Aminosalicylates (5-ASA, sulfasalazine and mesalazine) play a central role in the treatment of ulcerative colitis (UC). For acute treatment of mild to moderate flares and in maintenance treatment, their efficacy has been established. Since ulcerative colitis is limited to the distal colon in two thirds of the patients, topical therapy also plays an important role. In mild/moderate active disease 5-ASA 4 g/d is as effective as oral corticosteroids. Ulcerative proctitis is treated with 2 x 500 mg or 1 x 1 g suppositories and proctosigmoiditis with 1 to 4 g enemas. Oral 5-ASA is also safe in maintenance treatment and is generally well tolerated. The risk of colorectal tumours is increased in patients with longstanding ulcerative colitis and epidemiological evidence indicates that chronic 5-ASA treatment reduces this risk. However, at present there is insufficient evidence to maintain patients on life-long 5-ASA maintenance treatment for this indication.

Abstract
OBJECTIVE Infliximab is an effective treatment for refractory or fistulizing Crohn's disease (CD). However, about 30% of patients do not respond to infliximab for unknown reasons. Identifying predictive factors of response is important for optimizing clinical management and for better understanding infliximab's mechanisms of action. The aim of this study was to assess whether demographic or clinical parameters influence short-term response to infliximab. METHODS The first 240 CD patients of the Belgian Infliximab Expanded Access Program were studied for response to infliximab treatment and assessed at 4 (refractory luminal CD) or 10 wk (fistulizing CD) after the first infusion. Detailed demographic and clinical information on age, sex, type of disease (fistulizing or refractory), Crohn's Disease Activity Index score, C-reactive protein (CRP), smoking habits, disease duration, localization of disease, concomitant medication, and previous surgery were obtained from all patients. Logistic regression and decision tree analysis were performed. RESULTS There were 73.5% responders and 26.5% nonresponders to treatment. Stepwise logistic regression identified age (OR = 0.971, 95% CI = 0.947-0.995, p = 0.018), isolated ileitis (OR = 0.359, 95% CI = 0.177-0.728, p = 0.004), and previous surgery (OR = 0.429, 95% CI = 0.233-0.787, p = 0.006) as inversely correlated with response, whereas isolated colitis (OR = 1.905, 95% CI = 1.010-3.597, p = 0.046) and concomitant immunosuppressive treatment (OR = 2.670, 95% CI = 1.430-5.016, p = 0.0022) were positively correlated with response to infliximab. Surprisingly, smoking habits were not retained as predictors for response. Decision tree analysis provided a working algorithm based on age and immunosuppressive treatment that warrants further exploration. CONCLUSIONS In this large cohort of infliximab-treated CD patients, young age, Crohn's colitis, and concomitant immunosuppressive treatment were identified as independent variables favoring short-term response to infliximab.

Abstract
BACKGROUND & AIMS NOD2/CARD15 was recently identified as the first gene underlying Crohn's disease (CD) susceptibility. Monoclonal antibodies to tumor necrosis factor (TNF)-alpha (infliximab) are a potent treatment for CD, with about 70% of patients responding. It is not clear which factors influence treatment outcome. We assessed whether variants in NOD2/CARD15 are predictive for differences in clinical response. METHODS Two hundred forty-five CD patients (86 fistulizing, 159 luminal) receiving infliximab in an expanded access program were genotyped for the 3 main associated variants of NOD2/CARD15, without knowledge of the treatment response. Short-term clinical response was assessed at 4 weeks (refractory) or 10 weeks (fistulizing) after first infliximab infusion, and the mean duration of response was calculated. In a subgroup of patients, production of TNF in response to lipopolysaccharide (LPS) in mucosal biopsy tissue was also determined by means of immunoassay, and results were related to the different NOD2/CARD15 genotypes. RESULTS In total, 32.6% of patients carried mutations in NOD2/CARD15 (18.8% R702W, 8.6% G908R, and 10.2% 1007fs) compared with 15% in controls (P < 0.001). Despite observed differences in TNF production in mucosal biopsy tissue, there was no relationship between the overall presence of a mutation in NOD2/CARD15 or of any of the mutations separately and short-term infliximab response or response duration. Furthermore, multivariate analysis could not identify clinical characteristics that, in combination with NOD2/CARD15 mutations, were associated with response to infliximab. CONCLUSIONS In this cohort of CD patients, the frequency of NOD2/CARD15 mutations was significantly greater than that of healthy controls. However, NOD2/CARD15 was not predictive of treatment outcome with infliximab in CD.
