[PMID: 39001958 DOI: 10.1007/s10620-024-08543-1] [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: 04/29/2024] [Accepted: 06/21/2024] [Indexed: 07/15/2024]
Abstract
Elemental diets have been employed for the management of various diseases for over 50 years, with several mechanisms mediating their beneficial effects. Yet, they are underutilized due to poor palatability, access, cost, and lack of awareness regarding their clinical efficacy. Therefore, in this review, we aimed to systematically search and review the literature to summarize the formulation variability, mechanisms of action, clinical applications, and tolerability of the elemental diets in gastrointestinal diseases. While large prospective trials are lacking, elemental diets appear to exhibit objective and subjective clinical benefit in several diseases, including eosinophilic esophagitis, eosinophilic gastroenteritis, inflammatory bowel diseases, small intestinal bacterial overgrowth, intestinal methanogen overgrowth, chemoradiotherapy-associated mucositis, and celiac disease. Although some data support the long-term use of elemental diets as an add-on supplement for chronic pancreatitis and Crohn's disease, most of the literature on exclusive elemental diets focuses on inducing remission. Therefore, subsequent treatment strategies for maintaining remission need to be adopted in chronic/relapsing diseases. Several mechanistic pathways were identified to mediate the effects of elemental diets, including food additive and allergen-free content, high passive absorption rate, and anti-inflammatory properties. High rates of intolerance up to 40% are seen in the trials where exclusive elemental diets were administered orally due to poor organoleptic acceptability; however, when tolerated, adverse events were rare. Other limitations of elemental diets are cost, access, and lifestyle/social restrictions. Moreover, judicious use is advised in presence of a concomitant restrictive food intake disorders. Elemental diets offer a potentially highly efficacious dietary intervention with minor side effects. Palatability, cost, access, and social restrictions are common barriers of use. Prospective clinical trials are needed to elucidate the role of elemental formulas in the management of individual diseases.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1068. [PMID: 39064497 PMCID: PMC11278540 DOI: 10.3390/medicina60071068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 06/21/2024] [Accepted: 06/25/2024] [Indexed: 07/28/2024]
Abstract
Inflammatory bowel disease (IBD) poses significant challenges in its management, encompassing a spectrum of conditions from Crohn's disease to ulcerative colitis. Dietary interventions have emerged as integral components of the multidisciplinary approach to IBD management, with implications ranging from disease prevention to treatment of active manifestations and addressing complications such as malnutrition. While dietary interventions show promise in improving outcomes for some patients with IBD, there is no consensus in the existing literature regarding remission maintenance in those patients. Furthermore, many patients explore dietary modifications often guided by anecdotal evidence or personal experiences and this could lead to malnutrition and decreased quality of life. This comprehensive review synthesizes existing literature to elucidate the complex interplay between diet and IBD, offering insights into the efficacy and safety of various dietary modalities in maintaining disease remission. It also highlights the importance of patient education in navigating dietary choices and potential risks associated with food avoidance, including the heightened risk of micronutrient deficiencies. Furthermore, it emphasizes the pivotal role of a multidisciplinary care team comprising clinicians and dietitians in providing personalized dietary guidance tailored to individual patient needs and goals. By synthesizing the latest evidence and providing insights into both the potential benefits and risks of dietary interventions, this review could be used as a resource for healthcare professionals and patients alike in navigating the complex landscape of dietary management in IBD.

Abstract
Diet is a modifiable risk factor for disease course and data over the past decade have emerged to indicate its role in Crohn's disease (CD) and ulcerative colitis (UC). However, literature is riddled with misinterpretation of data, often leading to unexpected or conflicting results. The key understanding is that causative factors in disease development do not always proceed to an opportunity to change disease course, once established. Here, we discuss the data on dietary influences in three distinct disease states for CD and UC-predisease, active disease and quiescent disease. We appraise the literature for how our dietary recommendations should be shaped to prevent disease development and if or how that differs for CD and UC induction therapy and maintenance therapy. In UC, principles of healthy eating are likely to play a role in all states of disease. Conversely, data linking dietary factors to CD prevention and treatment are paradoxical with the highest quality evidence for CD treatment being exclusive enteral nutrition, a lactose, gluten and fibre-free diet comprising solely of ultraprocessed food-all dietary factors that are not associated or inversely associated with CD prevention. High-quality evidence from dietary trials is much awaited to expand our understanding and ultimately lead our dietary recommendations for targeted patient populations.

[PMID: 38168701 PMCID: PMC10824800 DOI: 10.1007/s00011-023-01828-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 08/14/2023] [Accepted: 11/27/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Adalimumab monotherapy can suppress gut inflammation and induce remission in active Crohn's disease but has some limitations. Exclusive enteral nutrition (EEN) is recommended for patients with mild to moderate Crohn's disease (CD), but implementation is challenging. AIM To evaluate the effectiveness of adalimumab combined with partial enteral nutrition (PEN) in the induction therapy for Crohn's disease. METHODS A prospective cohort study was designed and a total of 56 patients with active CD who met the criteria for enteral nutrition (EN) treatment in our hospital were selected. The baseline data of all patients were collected including age, sex and other general information. The changes in fecal calprotectin, C-reactive protein (CRP), albumin(Alb), hemoglobin (Hb), platelets (Plt), erythrocyte sedimentation rate (ESR), Crohn's disease activity index score (CDAI), simple endoscopic score (SES-CD) and body mass index (BMI) were compared between the adalimumab combined with enteral nutrition (ADA+EN) group (N = 37) the adalimumab group (ADA) (N = 19) at week 0 (W0) and treatment outcomes at week 12(W12). Additionally, the differences between the two groups before and after treatment were evaluated. Then the ADA+EN group was divided into an adalimumab combined with exclusive enteral nutrition subgroup (ADA+EEN) and an adalimumab combined with partial nutrition subgroup (ADA+PEN) according to enteral nutrition intake. The changes in fecal calprotectin, CRP, Alb, Hb, Plt, ESR and CDAI, SES-CD and BMI were compared between the ADA+EEN group and the ADA+PEN group at week 0 (W0) and treatment outcomes at week 12(W12). The differences between the two groups before and after treatment were evaluated. To evaluate the effectiveness of the two treatments on patients' quality of life, nutritional recovery and body composition, patients in the ADA+EN group were needed to complete the Inflammatory Bowel Disease Questionnaire (IBDQ), EQ-5D-5L, the EuroQol visual analogue scale (EQ-VAS) and body composition analysis.A total of 28 patients completed all questionnaires and body composition analyses at week 0 and week 12, including 10 patients in the ADA+EEN group and 18 patients in the ADA+PEN group, respectively. The differences of in IBDQ, EQ-5D-5L and body composition analysis were compared between the two groups at week 0 (W0) and treatment outcomes at week 12(W12). Additionally, the differences between the two groups before and after treatment were evaluated. RESULTS These investigated indexes such as calprotectin, Hb, Plt, ESR, Alb, BMI, CRP, CDAI and SES-CD scores were significantly different before and after treatment in the ADA+EN group (p < 0.01). However, fecal calprotectin, Hb, SES-CD scores and Alb in the ADA group were not statistically significantly different from W0 to W12 (p > 0.05). The fecal calprotectin and CDAI scores in the ADA+EN group were significantly lower than those in the ADA group after treatment. The differences in all factors before and after treatment between the ADA+PEN group and the ADA+EEN group were statistically significant (p < 0.05). However, there was no significant difference between the two groups at week 12 (p > 0.05). CONCLUSION Adalimumab combined with EN are more effective than ADA monotherapy in terms of endoscopy and clinical remission. By comparing the investigated indicators such as calprotectin, Hb, Plt, ESR ,CRP and SES-CD scores, it was proven that adalimumab combined with partial enteral nutrition or exclusive enteral nutrition has the same remission effect in induced Crohn's disease. The combination of biological agents and partial nutrition can improve medical order compliance, psychological burden and quality of life. Therefore, adalimumab combined with partial nutrition can be used as the first-line treatment for CD induced remission.

Abstract
There remains a paucity of data on the efficacy of nutritional interventions in luminal gastrointestinal disorders. This review appraises the evidence supporting dietary modification in gastroesophageal reflux disease (GERD), irritable bowel syndrome, Celiac disease, and inflammatory bowel disease. Alhough the use of elimination diets; high fat/low carb; low fermentable oligosaccharides, disaccharides, monosaccharides and polyols; and lactose-free diets in GERD have been studied, the evidence supporting their efficacy remains weak and mixed. Patients with GERD should avoid eating within 3 hours of lying recumbent. Studied dietary interventions for disorders of gut-brain interaction include low fermentable oligosaccharides, disaccharides, monosaccharides and polyols and gluten-restricted and lactose-free diets. While all can be effective in carefully, individually selected patients, the evidence for each intervention remains low. In patients with inflammatory bowel disease, enteral nutrition is established in pediatric populations as useful in reducing inflammation and partial enteral nutrition has a growing evidence base for use in adults and children. Specific carbohydrate diets and the Crohn's disease exclusion diet show promising evidence but require further study to validate their efficacy prior to recommendation. Overall, the evidence supporting nutritional therapy across luminal gastrointestinal disorders is mixed and often weak, with few well-designed randomized controlled trials (RCTs) demonstrating consistent efficacy of interventions. RCTs, particularly cross-over RCTs, show potential to compare dietary interventions.

Abstract
BACKGROUND Despite increased awareness of diet and nutrition being integral to the management of patients with inflammatory bowel disease (IBD), there are gaps in the knowledge of IBD healthcare providers regarding nutrition. Furthermore, high quality evidence on nutritional assessment and dietary management of IBD is limited. A Delphi consensus from a panel of experts allows for best-practice guidelines to be developed, especially where high quality evidence is limited. The aim was to develop guidelines for the nutritional assessment and dietary management of IBD using an eDelphi online consensus agreement platform. METHODS Seventeen research topics related to IBD and nutrition were systematically reviewed. Searches in Cochrane, Embase®, Medline® and Scopus® electronic databases were performed. GRADE was used to develop recommendations. Experts from the IBD community (healthcare professionals and patients with IBD) were invited to vote anonymously on the recommendations in a custom-built online platform. Three rounds of voting were carried out with updated iterations of the recommendations and evaluative text based on feedback from the previous round. RESULTS From 23,824 non-duplicated papers, 167 were critically appraised. Fifty-five participants completed three rounds of voting and 14 GRADE statements and 42 practice statements achieved 80% consensus. Comprehensive guidance related to nutrition assessment, nutrition screening and dietary management is provided. CONCLUSIONS Guidelines on the nutritional assessment and dietary management of IBD have been developed using evidence-based consensus to improve equality of care. The statements and practice statements developed demonstrate the level of agreement and the quality and strength of the guidelines.

Abstract
Enteral nutrition (EN) is a vital component of nutrition around the world. EN allows for delivery of nutrients to those who cannot maintain adequate nutrition by oral intake alone. Common questions regarding EN are when to initiate and in what scenarios it is safe. The answers to these questions are often complex and require an evidence-based approach. The Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) established an Enteral Nutrition Committtee to address the important questions surrounding the indications for EN. Consensus recommendations were established based on eight extremely clinically relevant questions regarding EN indications as deemed by the Enteral Nutrition Committee. These consensus recommendations may act as a guide for clinicians and stakeholders on difficult questions pertaining to indications for EN. This paper was approved by the ASPEN Board of Directors.

Abstract
OBJECTIVES Studies describing longer-term outcomes after EEN induction are limited. We describe clinical outcomes during 90:10 EN induction, and 6- and 12- month outcomes among patients that successfully completed EN induction and then continued either EN or immunomodulator (IM) maintenance therapy. METHODS All children with CD treated with 90:10 EN induction protocol (90% formula:10% regular diet) at our IBD Center from 2013 to 2018 were retrospectively reviewed. Demographic, clinical, and laboratory data were recorded at baseline, 6, and 12 months (± 3 months at each timepoint). Therapy changes after initiation of EN induction through 12 months were recorded. Among patients that successfully completed 90:10 induction, outcomes between EN and IM maintenance groups were compared. RESULTS In total, 44/105 (42%) patients completed 8-12 weeks of 90:10 EN induction. Sixty-one patients had incomplete EN induction, with 52% requiring corticosteroids and 25% anti-TNF therapy as alternate induction approaches. Forty-four patients completed EN induction (18 continued EN maintenance and 26 IM maintenance therapy). Twenty-seven of these 44 (61%) remained on initial maintenance therapy at 6 months (10/18 (56%) EN and 17/26 (65%) IM). In total, 16/44 (36%) remained on their initial maintenance therapy at 12 months. By 12 months, 10 patients required anti-TNF and 11 corticosteroids after successful completion of induction. CONCLUSIONS In this retrospective study of short and longer-term outcomes after 90:10 EN induction, the need for an alternate induction therapy was common, most frequently to anti-TNF or corticosteroid therapy. Future studies are needed to evaluate for predictors of long-term success after EN induction.

Perceived acceptability of partial enteral nutrition (PEN) using oral nutritional supplement drinks in adolescent and adult Crohn's disease outpatients: A feasibility study.

Abstract
BACKGROUND AND AIMS Studies, mainly in Japanese cohorts, have shown that partial enteral nutrition (PEN) including oral nutritional supplement (ONS) drinks can prolong disease remission and increase drug effectiveness in Crohn's disease (CD). Acceptability is a key feasibility parameter to determine whether PEN is a viable treatment option in UK CD patients. We report the results of a single centre cross-sectional feasibility study carried out to investigate perceived acceptability of PEN using ONS drinks and whether ONS preference varies with sex, nutritional status or phenylthiocarbamide (PTC) sensitivity. METHODS Patients with a confirmed CD diagnosis were recruited using convenience sampling from an adult and adolescent gastroenterology outpatient clinic over 3 years. Blind taste testing of 5 polymeric ONS drinks were conducted using a validated 9-point hedonic rating scale followed by completion of an acceptability questionnaire based on the preferred ONS drink. A subset of patients took home the preferred ONS drink for a 7-day ONS study. RESULTS 105 CD patients (55 males), aged 34.9 (±15.4) years were recruited and 28 patients completed the 7-day ONS study. Overall impression scores did not significantly vary with nutritional status, sex, BMI, handgrip strength (HGS), mid-upper arm circumference (MUAC) or PTC sensitivity. Ensure plus milkshake™ rated highest for overall impression (6.5, p=<0.0001) and all other organoleptic properties (p < 0.0001). The main perceived benefits of using ONS drinks as PEN related to assurance of nutrient intake (89%), convenience (86%), and improvement of gut symptoms (85%). The main perceived barriers related to reduction in pleasure from eating and drinking (56%), struggling with drink storage (54%) having less energy and feeling more tired than if eating 3 solid meals daily (52%). 65% of patients would consider using ONS drinks as PEN as a maintenance treatment option. 81% of patients felt confident-very confident about consuming ONS drinks daily as PEN for three months but this dropped to 64% and 37% at 6 and 12 months, respectively. There was a significant drop in perceived ease of use of ONS drinks as PEN after the 7-day ONS study (P = 0.01). CONCLUSION Use of ONS drinks as PEN have high perceived benefits and appear to be a feasible option for short-term use of 3-6 months in CD patients. However, confidence in long-term use of ONS drinks as PEN is low mainly due to the perceived social impact. Future studies should assess longer trial periods and volume of ONS drinks to increase the validity of these findings.

Abstract
Objectives: To evaluate the feasibility of our new preoperative enteral nutrition protocol using ElentalⓇ without mechanical bowel preparation (MBP) before laparoscopic anterior resection (LAR) in patients with advanced stenotic rectal cancer. Methods: Among 74 patients with advanced rectal cancer (clinical stages T3 and T4) scheduled to undergo LAR, 42 patients with stenotic rectal cancer were administered ElentalⓇ (900 kcal/day) without MBP before LAR (group S). Thirty-two patients without stenosis (group NS) did not receive preoperative nutritional support but underwent MBP. Results: Group S patients were maintained in a fasting state and received an elemental diet approximately 10 days preoperatively without severe adverse effects. The incidence of postoperative complications (Clavien-Dindo classification ≥ grade 2) was significantly lower in group S than that in group NS (adjusted odds ratio [OR]: 6.046, P = 0.008). Logistic regression analysis revealed that group NS exhibited higher risks of developing postoperative complications than those exhibited by group S (OR: 4.32, 95% confidence interval [CI]: 1.28-17.28, P = 0.018). Among preoperative characteristics, the clinical tumor stage indicated a significant intergroup difference. Thus, the clinical stage was selected as a covariate and adjusted in the logistic regression model to calculate a covariate-adjusted OR. Group NS exhibited a higher incidence of postoperative complications than group S (adjusted OR: 6.05, 95% CI: 1.58-28.35, P = 0.008). Conclusions: Administration of an elemental diet using ElentalⓇ without MBP before LAR is a feasible strategy in patients with advanced stenotic rectal cancer. Application of this research may encourage use of ElentalⓇ in the clinical setting.

Abstract
It has been widely endorsed that a multifactorial etiology, including interaction between genetic and environmental factors, can contribute to Crohn's Disease (CD) pathogenesis. More specifically, diet has proven to be able to shape gut microbiota composition and thus is suspected to play a significant role in inflammatory bowel disease (IBD) pathogenesis. Moreover, poor nutritional status and growth retardation, arising from several factors such as reduced dietary intake or nutrient leakage from the gastrointestinal tract, represent the hallmarks of pediatric CD. For these reasons, multiple research lines have recently focused on the utilization of dietary therapies for the management of CD, aiming to target concurrently mucosal inflammation, intestinal dysbiosis and optimization of nutritional status. The forerunner of such interventions is represented by exclusive enteral nutrition (EEN), a robustly supported nutritional therapy; however, it is burdened by monotony and low tolerance in the long term. Novel dietary interventions, such as Crohn's Disease Exclusion Diet or Crohn's Disease treatment with eating, have shown their efficacy in the induction of remission in pediatric patients with CD. The aim of the present narrative review is to provide a synopsis of the available nutritional strategies in the management of pediatric CD and to discuss their application in the dietary management of these patients.

Abstract
The food we eat is thought to play a role in both the increasing incidence as well as the course of Crohn's disease. What to eat and what to avoid is an increasingly important question for both patients and physicians. Restrictive diets are widely adopted by patients and carry the risk of inducing or worsening malnutrition, without any guarantees on anti-inflammatory potential. Nevertheless, exploration of novel therapies to improve long-term management of the disease is desperately needed and the widespread use of exclusive enteral nutrition in the induction of paediatric Crohn's disease makes us wonder if a similar approach would be beneficial in adult patients. This narrative review discusses the current clinical evidence on whole food diets in achieving symptomatic and inflammatory control in Crohn's disease and identifies knowledge gaps with areas for future research.

Abstract
OBJECTIVE We aimed to provide an evidence-supported update of the ECCO-ESPGHAN guideline on the medical management of paediatric Crohn's disease [CD]. METHODS We formed 10 working groups and formulated 17 PICO-structured clinical questions [Patients, Intervention, Comparator, and Outcome]. A systematic literature search from January 1, 1991 to March 19, 2019 was conducted by a medical librarian using MEDLINE, EMBASE, and Cochrane Central databases. A shortlist of 30 provisional statements were further refined during a consensus meeting in Barcelona in October 2019 and subjected to a vote. In total 22 statements reached ≥ 80% agreement and were retained. RESULTS We established that it was key to identify patients at high risk of a complicated disease course at the earliest opportunity, to reduce bowel damage. Patients with perianal disease, stricturing or penetrating behaviour, or severe growth retardation should be considered for up-front anti-tumour necrosis factor [TNF] agents in combination with an immunomodulator. Therapeutic drug monitoring to guide treatment changes is recommended over empirically escalating anti-TNF dose or switching therapies. Patients with low-risk luminal CD should be induced with exclusive enteral nutrition [EEN], or with corticosteroids when EEN is not an option, and require immunomodulator-based maintenance therapy. Favourable outcomes rely on close monitoring of treatment response, with timely adjustments in therapy when treatment targets are not met. Serial faecal calprotectin measurements or small bowel imaging [ultrasound or magnetic resonance enterography] are more reliable markers of treatment response than clinical scores alone. CONCLUSIONS We present state-of-the-art guidance on the medical treatment and long-term management of children and adolescents with CD.

Abstract
Although enteral nutrition (EN) is effective for induction therapy in Crohn's disease (CD), it remains unclear whether partial enteral nutrition (PEN), i.e., EN, along with a daily diet, is effective for maintenance therapy in CD. It was hypothesized that PEN would be effective as a maintenance therapy in CD. This meta-analysis aimed to evaluate the efficacy and safety of PEN for maintenance therapy in CD. PubMed, EMBASE, Web of Science, and Cochrane Library were searched up to January 2019 for eligible prospective controlled trials, and then a meta-analysis was conducted. The primary outcome was clinical relapse, as defined in the primary studies. Eight studies with 429 patients were included in the meta-analysis. The rate of clinical relapse at 0.5 to 2 years was significantly lower in patients receiving PEN (420-1800 kcal/d) than in those not receiving nutrition therapy (RR: 0.67, 95% CI: 0.54-0.82, P < .01; number needed to treat = 5, P < .01). Patients receiving PEN exhibited a higher frequency of clinical remission maintenance at 0.5 to 1 year (67%) than did those not receiving nutrition therapy (48%; RR: 1.32, 95% CI: 1.07-1.64, P = .01). The total adverse event rate was comparable in the two groups (RR: 3.60, 95% CI: 0.70-18.66, P = .13). PEN may be more effective than the absence of EN therapy for the maintenance of remission in CD with a good safety profile.

Abstract
Elental® is an L-glutamine-rich elemental diet (ED) that has been widely used in Japan as a nutritional supplement for malnourished patients. In addition, Elental® has been successfully used in the management of chemotherapy-induced mucositis in cancer patients. Recently, it was also reported that Elental® can effectively reduce chemotherapy-induced oral mucositis in patients with oral squamous cell carcinoma, and can also reduce mucositis and dermatitis in animal models. However, it is unclear whether oral intake or topical application of Elental® can act directly on chemotherapy-induced oral mucositis or dermatitis. The aim of the present study was to investigate the possible direct healing effect of Elental® on chemotherapy-induced dermatitis and raw wound areas in a mouse model. Dermatitis and raw wounds were induced in nude mice by administration of 5-fluorouracil (5-FU) (via gastric tube) and mechanical injury (using a metal brush or a surgical knife). We then compared the outcome following oral or topical application of Elental® in these mice. The effect of Elental® on the growth and migration ability of the human oral keratinocyte cell line, HOK, was also examined using MTT and migration assays, respectively. In the mouse model, both oral administration and topical application of Elental® reduced 5-FU-induced dermatitis and healed raw wound areas more effectively compared with the topical application of saline. The MTT assay revealed that Elental® exerted a growth-promoting effect on HOKs. In addition, Elental® enhanced the ability of HOKs to migrate, as demonstrated by the migration assay. These findings demonstrated that the topical application as well as the oral intake of Elental® exerted a direct healing effect on chemotherapy-induced dermatitis or raw wound areas. The data also indicated that oral intake of an ED may exert a direct healing effect on chemotherapy-induced oral mucositis.

Abstract
The etiopathogenesis of Inflammatory bowel disease (IBD) is a result of a complex interaction between host immune response, the gut microbiome and environmental factors, such as diet. Although scientific advances, with the use of biological medications, have revolutionized IBD treatment, the challenge for maintaining clinical remission and delaying clinical relapse is still present. As exclusive enteral nutrition has become a well-established treatment for the induction of remission in pediatric Crohn's disease, the scientific interest regarding diet in IBD is now focused on the development of follow-on dietary strategies, which aim to suppress colonic inflammation and delay a disease flare. The objective of this review is to present an extensive overview of the dietary strategies, which have been used in the literature to maintain clinical remission in both Crohn's disease and Ulcerative colitis, and the evidence surrounding the association of dietary components with clinical relapse. We also aim to provide study-related recommendations to be encompassed in future research studies aiming to investigate the role of diet during remission periods in IBD.

Abstract
Medical and surgical treatments for Crohn's disease are associated with toxic effects. Medical therapy aims for mucosal healing and is achievable with biologics, immunosuppressive therapy, and specialised enteral nutrition, but not with corticosteroids. Sustained remission remains a therapeutic challenge. Enteral nutrition, containing macro- and micro-nutrients, is nutritionally complete, and is provided in powder or liquid form. Enteral nutrition is a low-risk and minimally invasive therapy. It is well-established and recommended as first line induction therapy in paediatric Crohn's disease with remission rates of up to 80%. Other than in Japan, enteral nutrition is not routinely used in the adult population among Western countries, mainly due to unpalatable formulations which lead to poor compliance. This study aims to offer a comprehensive review of available enteral nutrition formulations and the literature supporting the use and mechanisms of action of enteral nutrition in adult Crohn's disease patients, in order to support clinicians in real world decision-making when offering/accepting treatment. The mechanisms of actions of enteral feed, including their impact on the gut microbiome, were explored. Barriers to the use of enteral nutrition, such as compliance and the route of administration, were considered. All available enteral preparations have been comprehensively described as a practical guide for clinical use. Likewise, guidelines are reported and discussed.

Abstract
BACKGROUND Faecal calprotectin decreases during exclusive enteral nutrition in children with active Crohn's disease. It is unknown how faecal calprotectin changes during food re-introduction and the influence of maintenance enteral nutrition. AIMS To study changes to faecal calprotectin during exclusive enteral nutrition and at food reintroduction, and explore associations with maintenance enteral nutrition. METHODS Children with Crohn's disease were followed during exclusive enteral nutrition and during food-reintroduction. Faecal calprotectin was measured before, at 33 and 54 days of exclusive enteral nutrition, and at 17, 52 and 72 days after food-reintroduction. Maintenance enteral nutrition use was recorded with estimated weight food diaries. Data are presented with medians and Q1:Q3. RESULTS Sixty-six patients started exclusive enteral nutrition and 41 (62%) achieved clinical remission (weighted paediatric Crohn's disease activity index <12.5). Baseline faecal calprotectin (mg/kg) decreased after 4 and 8 weeks of exclusive enteral nutrition (Start: 1433 [Q1: 946, Q3: 1820] vs 33 days: 844 [314, 1438] vs 54 days: 453 [165, 1100]; P < .001). Within 17 days of food reintroduction, faecal calprotectin increased to 953 [Q1: 519, Q3: 1611] and by 52 days to 1094 [660, 1625] (both P < .02). Fifteen of 41 (37%) children in remission used maintenance enteral nutrition (333 kcal or 18% of energy intake). At 17 days of food reintroduction, faecal calprotectin was lower in maintenance enteral nutrition users than non-users (651 [Q1: 271, Q3: 1781] vs 1238 [749, 2102], P = .049) and correlated inversely with maintenance enteral nutrition volume (rho: -0.573, P = .041), kcals (rho: -0.584, P = .036) and % energy intake (rho: -0.649, P = .016). Maintenance enteral nutrition use was not associated with longer periods of remission (P = .7). Faecal calprotectin at the end of exclusive enteral nutrition did not predict length of remission. CONCLUSIONS The effect of exclusive enteral nutrition on faecal calprotectin is diminished early during food reintroduction. Maintenance enteral nutrition at ~18% of energy intake is associated with a lower faecal calprotectin at the early phase of food reintroduction but is ineffective in maintaining longer term remission.

Abstract
Patients frequently wonder whether their dietary pattern influences the course of inflammatory bowel disease (IBD). Many patients even avoid certain foods that aggravate their symptoms. Although interest in nutritional interventions is rising among physicians, the current application of nutritional interventions in the IBD population is limited due to the lack of scientific evidence from clinical trials. Several studies, however, have identified associations between diet, gut microbiota, intestinal epithelial integrity, and mucosal immune responses. In patients consuming predominantly a Western diet high in n-6 poly-unsaturated fatty acids (PUFAs), sugars, and meat, and low in fruits and vegetables, an impaired gut epithelial barrier and disturbances in the intestinal microbiota have been observed, resulting in a chronic mucosal inflammation. An anti-inflammatory diet may restore this disbalance. In this review, we discuss the effects of diet on the composition of the microbiota, the gut epithelial barrier function, and the mucosal immune system.

Abstract
Background and Aim Enteral nutrition (EN) is applicable to adult Crohn's disease (CD) in treating malnutrition and in inducing remission - here as a less effective alternative than corticosteroids. The purpose of this review is to determine whether preoperative EN impacts postoperative complications of adult CD, either by means of nutritional or therapeutic effects. Summary A systematic review of English written full-text research articles published between January 1990 and November 2017, including adult patients undergoing abdominal surgery for complicated CD after EN, was performed. Four studies out of 22 were selected, all of which institutional, retrospective, case-control cohorts, one classified as "good quality" and three as "poor quality," as rated by the Newcastle-Ottawa Scale. The application of inclusion and exclusion criteria resulted in a non-intentional absence of studies referring to supplemental EN among those reviewed. The reduced number of heterogeneous eligible studies impeded meta-analysis. In all studies, exclusive EN (EEN) was used and well tolerated, allowing to defer or even avoid surgery altogether, improving patients' global state. The two studies with the greatest number of patients found preoperative EEN to be an independent factor against infectious and non-infectious complications in 219 patients and against anastomotic leaks or abscesses in 38 patients. Also, in univariate analysis, EEN was found to increase preop-erative immunosuppressant-free intervals and to protect against anastomotic dehiscences, intra-abdominal abscesses, surgical wound infections, ileus, stomas, and reoperations in the largest study; in another study it was related to fewer intra-abdominal septic complications. Key Messages All reviewed studies are retrospective and, consequently, of limited relevance. Nonetheless, all of them call the attention of the scientific community to the potential benefits of preoperative EEN on postoperative outcomes in adult CD, calling for prospective multi-institutional studies and randomized controlled trials.

Abstract
Recent advances in basic and clinical science over the last 3 years have dramatically altered our appreciation of the role of diet in inflammatory bowel diseases (IBD). The marked increase in incidence of these diseases along with the important role of non-genetic susceptibility among patients with IBD has highlighted that these diseases have a strong environmental component. Progress in the field of microbiome and IBD has demonstrated that microbiome appears to play an important role in pathogenesis, and that diet may in turn impact the composition and functionality of the microbiome. Uncontrolled clinical studies have demonstrated that various dietary therapies such as exclusive enteral nutrition and newly developed exclusion diets might be potent tools for induction of remission at disease onset, for patients failing biologic therapy, as a treatment for disease complications and in reducing the need for surgery. We review these advances from bench to bedside, along with the need for better clinical trials to support these interventions.

Abstract
BACKGROUND Prevention of relapse is a major issue in the management of quiescent Crohn's disease (CD). Current therapies (e.g. methotrexate, biologics, 6-mercaptopurine and azathioprine) may be effective for maintaining remission in CD, but these drugs may cause significant adverse events. Interventions that are effective and safe for maintenance of remission in CD are desirable. OBJECTIVES The primary objectives were to evaluate the efficacy and safety of enteral nutrition for the maintenance of remission in CD and to assess the impact of formula composition on effectiveness. SEARCH METHODS We searched MEDLINE, Embase, CENTRAL, the Cochrane IBD Group Specialized Register and clinicaltrials.gov from inception to 27 July 2018. We also searched references of retrieved studies and reviews. SELECTION CRITERIA Randomised controlled trials (RCTs) including participants of any age with quiescent CD were considered for inclusion. Studies that compared enteral nutrition with no intervention, placebo or any other intervention were selected for review. DATA COLLECTION AND ANALYSIS Two authors independently screened studies for inclusion, extracted data and assessed methodological quality using the Cochrane risk of bias tool. The primary outcome was clinical or endoscopic relapse as defined by the primary studies. Secondary outcomes included anthropometric measures (i.e. height and weight), quality of life (QoL), adverse events, serious adverse events and withdrawal due to adverse events. We calculated the risk ratio and 95% confidence interval (CI) for dichotomous outcomes. For continuous outcomes, we calculated the mean difference and 95% CI. A random-effects model was used for the statistical analysis. We used the GRADE criteria to assess the overall certainty of the evidence supporting the primary outcome and selected secondary outcomes. MAIN RESULTS Four RCTs (262 adult participants) met the inclusion criteria. One study (N = 33) compared an elemental diet to a non-elemental (polymeric) diet. One study (N = 51) compared a half elemental diet to a regular free diet. Another study (N = 95) compared an elemental diet to 6-mercaptopurine (6-MP) or a no treatment control group. One study (N= 83) compared a polymeric diet to mesalamine. Two studies were rated as high risk of bias due to lack of blinding or incomplete outcome data. The other two studies were judged to have an unclear risk of bias. The studies were not pooled due to differences in control interventions and the way outcomes were assessed.The effect of an elemental diet compared to a polymeric diet on remission rates or withdrawal due to adverse events is uncertain. Fifty-eight per cent (11/19) of participants in the elemental diet group relapsed at 12 months compared to 57% (8/14) of participants in the polymeric diet group (RR 1.01, 95% CI 0.56 to 1.84; very low certainty evidence). Thirty-two per cent (6/19) of participants in the elemental diet group were intolerant to the enteral nutritional formula because of taste or smell and were withdrawn from the study in the first 2 weeks compared to zero participants (0/14) in the polymeric diet group (RR 9.75, 95% CI 0.59 to 159.93; low certainty evidence). Anthropometric measures, QoL, adverse events and serious adverse events were not reported as outcomes.The effect of an elemental diet (half of total daily calorie requirements) compared to a normal free diet on relapse rates is uncertain. Thirty-five per cent (9/26) of participants in the elemental diet group relapsed at 12 months compared to 64% (16/25) of participants in the free diet group (RR 0.54, 95% CI 0.30 to 0.99; very low certainty evidence). No adverse events were reported. This study reported no differences in weight change between the two diet groups. Height and QoL were not reported as outcomes.The effect of an elemental diet compared to 6-MP on relapse rates or adverse events is uncertain. Thirty-eight per cent (12/32) of participants in the elemental diet group relapsed at 12 months compared to 23% (7/30) of participants in the 6-MP group (RR 1.61; 95% CI 0.73 to 3.53; very low certainty evidence). Three per cent (1/32) of participants in the elemental diet group had an adverse event compared to 13% (4/30) of participants in the 6-MP group (RR 0.23, 95% CI 0.03 to 1.98; low certainty evidence). Adverse events in the elemental diet group included surgery due to worsening CD. Adverse events in the 6-MP group included liver injury (n = 2), hair loss (n = 1) and surgery due to an abscess (n = 1). No serious adverse events or withdrawals due to adverse events were reported. Weight, height and QoL were not reported as outcomesThe effect of a polymeric diet compared to mesalamine on relapse rates and weight is uncertain. Forty-two per cent (18/43) of participants in the polymeric diet group relapsed at 6 months compared to 55% (22/40) of participants in the mesalamine group (RR 0.76; 95% CI 0.49 to 1.19; low certainty evidence). The mean difference in weight gain over the study period was 1.9 kg higher in the polymeric diet group compared to mesalamine (95% CI -4.62 to 8.42; low certainty evidence). Two participants in the polymeric diet group experienced nausea and four had diarrhoea. It is unclear if any participants in the mesalamine group had an adverse event. Height, QoL, serious adverse events and withdrawal due to adverse events were not reported as outcomes. AUTHORS' CONCLUSIONS The results for the outcomes assessed in this review are uncertain and no firm conclusions regarding the efficacy and safety of enteral nutrition in quiescent CD can be drawn. More research is needed to determine the efficacy and safety of using enteral nutrition as maintenance therapy in CD. Currently, there are four ongoing studies (estimated enrolment of 280 participants). This review will be updated when the results of these studies are available.

Abstract
AIM This paper describes the outcomes of gastrostomy feeding in patients with Crohn's disease (CD). METHODS Patients with CD who attended the Royal Hospital for Children, Glasgow and received gastrostomy feeding for at least two years between 2003 and 2010 were identified from the clinical database. The data recorded included the anthropometric data, CD phenotype, the surgical technique that was used, complications, medication, feed type, median feed, calories, volume and clinical outcomes. RESULTS The study identified 16 patients (14 male) who had a gastrostomy inserted using a pull technique at a median age of 12.6 years. Of these two required laparoscopic placement. Short-term complications lasting less than one month were experienced by nine (56%) patients and one (6%) experienced long-term complications. Anthropometry significantly improved at follow-up compared to baseline: at 12 months, the body mass index z-score was 1.11 (p = 0.005) and the weight z-score was 0.19 (p < 0.05). At 24 months, the height z-score was -1.03 (p = 0.04). The daily median volume and calories from feeds increased significantly from baseline to post-PEG insertion, from 400 to 738 mL and 705 to 860 kcal/day (p ≤ 0.01). CONCLUSION Gastrostomy feeding for paediatric patients with CD was associated with improved nutrition, weight gain and growth outcomes.

Abstract
Nutritional strategies have been explored as primary or adjunct therapies for inflammatory bowel disease (IBD). Exclusive enteral nutrition is effective for the induction of remission in Crohn disease and is recommended as a first-line therapy for children. Dietary strategies focus on adjusting the ratio of consumed nutrients that are proinflammatory or antiinflammatory. Treatments with dietary supplements focus on the antiinflammatory effects of the individual supplements (eg, curcumin, omega-3 fatty acids, vitamin D) or their positive effects on the intestinal microbiome (eg, prebiotics, probiotics). This article discusses the role of diets and dietary supplements in the treatment of IBD.

Abstract
AIM Paediatric Crohn's disease (CD) is associated with growth delay and poor nutritional status. Maintenance enteral nutrition (MEN) supplementation is a potential adjunct to improve growth/prolong remission. METHODS Newly diagnosed CD patients were identified. Anthropometry, treatments and outcomes were collected for 12 months following diagnosis. Data are presented as medians. RESULTS A total of 102 patients were identified (age = 13 years, 76% male), 58 (57%) completed exclusive enteral nutrition (EEN) as induction therapy, and 77 (75%) entered clinical remission. Following induction, 58 (57%) of all patients continued MEN and 44 (43%) consumed normal diet (ND). BMI Z-score increased (diagnosis-12 months) for EEN (-1.41 to -0.21 (p = <0.0001)) and steroid groups (-0.97 to -0.11 (p = 0.001)). BMI Z-score increased (post induction - 12 months) for MEN (-0.62 to -0.44 (p = 0.04)) but not ND (-0.33 to -0.4 (p = 0.79)). Height Z-score did not increase for any treatment group over 12 months. MEN and ND group relapse rates were similar at six months, MEN = 21/58 (36%); ND = 21/44 (48%) (p = 0.24) and 12 months, MEN = 24/58 (41%); ND = 13/44 (30%) (p = 0.22). Fewer patients treated with EEN then MEN relapsed less than six months, 14 of 43 (33%), compared to patients treated with steroids then ND 16/29 (55%) (p = 0.09). CONCLUSION BMI Z-score increased but height Z-score remained unchanged over 12 months for the MEN group. Use of MEN was not associated with prolonged time to relapse. Prospective studies are required to examine the utility of MEN.

Abstract
Although the current doctrine of IBD pathogenesis proposes an interaction between environmental factors and gut microbiota in genetically susceptible individuals, dietary exposures have attracted recent interest and are, at least in part, likely to explain the rapid rise in disease incidence and prevalence. The D-ECCO working group along with other ECCO experts with expertise in nutrition, microbiology, physiology, and medicine reviewed the evidence investigating the role of diet and nutritional therapy in the onset, perpetuation, and management of IBD. A narrative topical review is presented where evidence pertinent to the topic is summarised collectively under three main thematic domains: i] the role of diet as an environmental factor in IBD aetiology; ii] the role of diet as induction and maintenance therapy in IBD; and iii] assessment of nutritional status and supportive nutritional therapy in IBD. A summary of research gaps for each of these thematic domains is proposed, which is anticipated to be agenda-setting for future research in the area of diet and nutrition in IBD.

Abstract
Mucositis and dermatitis induced by anticancer agents are common complications of anticancer therapies. In this study, we evaluated the efficacy of Elental (Ajinomoto Pharmaceutical Ltd, Tokyo, Japan), an elemental diet with glutamine in the treatment of 5-fluorouracil (5-FU)-induced oral mucositis and dermatitis in vivo and tried to clarify the underlying mechanisms of its action. Oral mucositis and dermatitis was induced through a combination of 5-FU treatment and mild abrasion of the cheek pouch in hamsters and the dorsal skin in nude mice respectively. These animals received saline, dextrin or Elental suspension (18 kcal/100 g) by a gastric tube daily until sacrifice. Elental reduced oral mucositis and dermatitis more effectively than dextrin in the animal model. Moreover, growth facilitating effects of Elental on HaCaT cells were examined in vitro. MTT assay, wound healing assay, and migration assay revealed that Elental could enhance the growth, invasion, and migration ability of HaCaT. ELISA and Western blotting showed upregulated FGF2 in Elental-treated HaCaT. These findings suggest that Elental is effective for the treatment of mucositis and dermatitis, and may accelerate mucosal and skin recovery through FGF2 induction and reepithelization.

Elental® amino acid component has protective effects on primary cultured hepatocytes and a rat model of acute liver injury. Nutr Res 2017.

Abstract
Amino acids can exert protective effects on the liver either when administered as a medication or following an operation. In this study, we examined the protective effects of amino acids on the liver using in vitro and in vivo models by studying their influence on the induction of inducible nitric oxide synthase (iNOS) and nitric oxide production as a liver injury marker in cultured hepatocytes and liver-protective effects in d-galactosamine and lipopolysaccharide (GalN/LPS)-treated rats, respectively. Primary cultured rat hepatocytes were treated with interleukin (IL)-1β in the presence or absence of Elental® amino acid component (EleAA; 17 amino acids). Rats were pretreated with either EleAA or a diet containing selected amino acids followed by GalN/LPS injection. Survival rate and mRNA expression were analyzed. EleAA inhibited iNOS induction through reduction of mRNA synthesis and stability in cultured hepatocytes, indicating prevention of liver injury, but did not show a liver-protective effect in GalN/LPS rats. Among EleAA, Lys, Trp, His, and Arg (4AA) markedly decreased nitric oxide production and inhibited nuclear factor-κB (NF-κB) activation. In GalN/LPS rats, 4AA (3% of each amino acid in diet) increased survival rate by 50% and decreased mRNA expression of iNOS, tumor necrosis factor-α, and cytokine-induced neutrophil chemoattractant-1 in the liver. 4AA reduced NF-κB activation induced by GalN/LPS. 4AA inhibited the expression of inflammatory mediators, in part through inhibition of NF-κB activation in cultured hepatocytes and GalN/LPS-treated rats. The results suggest that EleAA has therapeutic potential for organ injuries including liver.

Abstract
INTRODUCTION The ESPEN guideline presents a multidisciplinary focus on clinical nutrition in inflammatory bowel disease (IBD). METHODOLOGY The guideline is based on extensive systematic review of the literature, but relies on expert opinion when objective data were lacking or inconclusive. The conclusions and 64 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. RESULTS IBD is increasingly common and potential dietary factors in its aetiology are briefly reviewed. Malnutrition is highly prevalent in IBD - especially in Crohn's disease. Increased energy and protein requirements are observed in some patients. The management of malnutrition in IBD is considered within the general context of support for malnourished patients. Treatment of iron deficiency (parenterally if necessary) is strongly recommended. Routine provision of a special diet in IBD is not however supported. Parenteral nutrition is indicated only when enteral nutrition has failed or is impossible. The recommended perioperative management of patients with IBD undergoing surgery accords with general ESPEN guidance for patients having abdominal surgery. Probiotics may be helpful in UC but not Crohn's disease. Primary therapy using nutrition to treat IBD is not supported in ulcerative colitis, but is moderately well supported in Crohn's disease, especially in children where the adverse consequences of steroid therapy are proportionally greater. However, exclusion diets are generally not recommended and there is little evidence to support any particular formula feed when nutritional regimens are constructed. CONCLUSIONS Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 64 recommendations, of which 9 are very strong recommendations (grade A), 22 are strong recommendations (grade B) and 12 are based only on sparse evidence (grade 0); 21 recommendations are good practice points (GPP).

Abstract
It is now widely acknowledged that the intestinal bacterial flora together with genetic predisposing factors significantly contribute to the immunopathogenesis of inflammatory bowel disease (IBD) as reflected by mucosal immune dysregulation. Recently, there has been an increased interest in nutraceutical therapies, including probiotics, prebiotics and synbiotics. Other dietary interventions with low carbohydrate diet, omega-3 polyunsaturated fatty acids and glutamine have been attempted to downregulate the gut inflammatory response and thereby alleviate gastrointestinal symptoms. Enteral nutrition has been widely used as induction and maintenance therapies in the management of Crohn's disease (CD). In this review, a critical assessment of the results of clinical trial outcomes and meta-analyses was conducted to evaluate the efficacy of dietary and enteral interventions for CD.

Abstract
Atrophic glossitis is a condition characterised by absence of filiform or fungiform papillae on the dorsal surface of the tongue. Consequently, the ordinary texture and appearance of the dorsal tongue, determined by papillary protrusion, turns into a soft and smooth aspect. Throughout the years, many factors, both local and systemic, have been associated with atrophic glossitis as the tongue is currently considered to be a mirror of general health. Moreover, various tongue conditions were wrongly diagnosed as atrophic glossitis. Oral involvement can conceal underlying systemic conditions and, in this perspective, the role of clinicians is fundamental. Early recognition of oral signs and symptoms, through a careful examination of oral anatomical structures, plays a crucial role in providing patients with a better prognosis.

Abstract
Aim. This study was performed to evaluate the additional enteral nutrition (EN) in the efficacy of infliximab (IFX) compared with the conventional therapy in managing Crohn's disease (CD) complicated with intestinal fistulas. Methods. A total of 42 CD with intestinal fistulas were randomly divided into infliximab treatment group (n = 20) and conventional therapy group (n = 22). We evaluated the laboratory indexes, Crohn's disease activity index (CDAI), Crohn's disease simplified endoscopic score (SES-CD), and healing of fistula in the two groups before treatment, at 14 weeks, and at 30 weeks, respectively. Results. In the IFX treatment group, the CDAI score, the SES-CD, erythrocyte sedimentation rate, and C-reactive protein levels were significantly decreased during treatment compared with those before treatment. The body mass index and albumin levels were increased in both groups. Moreover, in the IFX treatment group, fistula healing was found in 8 at the 14th week and 18 at the 30th week, respectively, which was greater than that in the conventional therapy group. Conclusion. Our study suggested that infliximab combined with EN is an effective treatment for CD patients complicated with intestinal fistulas.

Abstract
Although patients with inflammatory bowel diseases (IBD) have a strong interest in dietary modifications as part of their therapeutic management, dietary advice plays only a minor part in published guidelines. The scientific literature shows that dietary factors might influence the risk of developing IBD, that dysbiosis induced by nutrition contributes to the pathogenesis of IBD, and that diet may serve as a symptomatic treatment for irritable bowel syndrome-like symptoms in IBD. The role of nutrition in IBD is underscored by the effect of various dietary therapies. In paediatric patients with Crohn’s disease (CD) enteral nutrition (EN) reaches remission rates similar to steroids. In adult patients, however, EN is inferior to corticosteroids. EN is not effective in ulcerative colitis (UC). Total parenteral nutrition in IBD is not superior to steroids or EN. The use of specific probiotics in patients with IBD can be recommended only in special clinical situations. There is no evidence for efficacy of probiotics in CD. By contrast, studies in UC have shown a beneficial effect in selected patients. For patients with pouchitis, antibiotic treatment followed by probiotics, like VSL#3 or Lactobacillus GG, is effective. When probiotics are used, the risk of bacterial translocation and subsequent bacteremia has to be considered. More understanding of the normal intestinal microflora, and better characterization of probiotic strains at the phenotypic and genomic levels is needed as well as clarification of the mechanisms of action in different clinical settings. A FODMAP reduced diet may improve symptoms in IBD.

Abstract
Inflammatory bowel diseases (IBD), including ulcerative colitis and Crohn's disease are chronic, life-long, and relapsing diseases of the gastrointestinal tract. Currently, there are no complete cure possibilities, but combined pharmacological and nutritional therapy may induce remission of the disease. Malnutrition and specific nutritional deficiencies are frequent among IBD patients, so the majority of them need nutritional treatment, which not only improves the state of nutrition of the patients but has strong anti-inflammatory activity as well. Moreover, some nutrients, from early stages of life are suspected as triggering factors in the etiopathogenesis of IBD. Both parenteral and enteral nutrition is used in IBD therapy, but their practical utility in different populations and in different countries is not clearly established, and there are sometimes conflicting theories concerning the role of nutrition in IBD. This review presents the actual data from research studies on the influence of nutrition on the etiopathogenesis of IBD and the latest findings regarding its mechanisms of action. The use of both parenteral and enteral nutrition as therapeutic methods in induction and maintenance therapy in IBD treatment is also extensively discussed. Comparison of the latest research data, scientific theories concerning the role of nutrition in IBD, and different opinions about them are also presented and discussed. Additionally, some potential future perspectives for nutritional therapy are highlighted.

Abstract
PURPOSE The value of enteral nutrition (EN) as maintenance therapy in patients with quiescent Crohn's disease (CD) has not been fully evaluated. The purpose of this study was to review the efficacy of EN for the maintenance of remission in patients with quiescent CD. METHODS Seven prospective cohort studies evaluating the efficacy of EN for the maintenance of remission in quiescent CD were included. Three of the seven studies were randomized-controlled trials (RCTs). In all studies, patients used EN as a supplement or as a nocturnal tube feeding in addition to their normal food. RESULTS One study compared the efficacy of elemental diet and polymeric diet. Elemental and polymeric diets were equally effective for the maintenance of clinical remission and for allowing tapering and cessation of steroid therapy. The other six studies compared the outcomes between patients treated with and without EN. The maintained clinical remission rate at 1 year was significantly higher in patients treated with EN in four of the six studies. Quantitative pooling of the studies was not feasible due to a small number of RCTs and a narrative account of the study characteristics. CONCLUSIONS Our review suggests that EN is useful for the maintenance of remission in patients with quiescent CD. However, there are several limitations in the reviewed studies. There are few RCTs. Further, the sample size is small, and the duration of intervention and follow-up is short. Large and well-designed RCTs should be conducted to rigorously evaluate the efficacy of EN for maintaining remission.

Abstract
BACKGROUND Although enteral nutrition has been shown to be a viable treatment option for the management of active Crohn's disease (CD), the evidence regarding its clinical benefits compared with standard treatments (e.g. steroids) for maintaining remission in patients with CD has been inconsistent. If enteral nutrition was to be effective, the use of drugs such as steroids and immunosuppressive drugs could be reduced, thereby reducing the likelihood of adverse events associated with these medications. OBJECTIVES This systematic review aimed to assess the clinical effectiveness and cost-effectiveness of elemental nutrition (a type of enteral nutrition) for maintenance of remission in patients with CD. DATA SOURCES Major bibliographic databases (e.g. MEDLINE, EMBASE, Cochrane Database of Systematic Reviews) were searched from inception to August/September 2013. Searches were not limited by study design, language or publication date. Websites for relevant organisations and references of included studies were checked. METHODS Experimental randomised and non-randomised controlled trials (RCTs and nRCTs) reporting clinical effectiveness and cost-effectiveness of elemental nutrition in the maintenance of remission in patients with CD were eligible. Study selection, data extraction and risk of bias (RoB) assessment were performed independently. Risk ratios (RRs) and mean differences (MDs) were pooled using a random-effects model. Heterogeneity was assessed via forest plots, Cochran's Q and the I2 statistics. Overall, quality of evidence for each outcome was rated using the Grading of Recommendations, Assessment, Development, and Evaluation approach. RESULTS Eight studies (three RCTs and five nRCTs) were included in the review. RCTs indicated a significant benefit of elemental nutrition vs. no intervention (an unrestricted diet) in maintaining remission at 24 months [one RCT; RR 2.06, 95% confidence interval (CI) 1.00 to 4.43; very low-grade evidence] and preventing relapse at 12-24 months post baseline (two RCTs; pooled RR 0.57, 95% CI 0.38 to 0.84; I2 = 0%; high-grade evidence). Similarly, three nRCTs showed significant benefits of elemental nutrition over no intervention in maintaining remission at 12-48 months and preventing relapse at 12 months post baseline (MD 1.20 months, 95% CI 0.35 to 2.04 months). The incidence of mucosal healing was not significantly different in the intervention and control groups (RR 2.70, 95% CI 0.62 to 11.72). Adherence to an elemental nutrition regime was significantly worse than adherence to polymeric nutrition (RR 0.68, 95% CI 0.50 to 0.92) and, when compared with other active treatments (medications, polymeric nutrition or a combination), elemental nutrition yielded non-significant results with wide 95% CIs, rendering these results inconclusive. Complications and adverse events were too sparse to allow meaningful comparisons. None of the studies reported cost-effectiveness of elemental nutrition. Owing to scarcity of data, subgroup and sensitivity analyses could not be performed to explore methodological and clinical sources of heterogeneity. LIMITATIONS The findings warrant cautious interpretation given the limitations of the evidence in methodological quality (small samples, short follow-up) and the RoB in individual studies (lack of blinding, confounding). CONCLUSIONS Limited evidence indicates potential benefits of elemental nutrition against no intervention in the maintenance of remission and prevention of relapse in adult patients with CD. There was a lack or insufficient evidence on adverse events and complications. Future large and long-term randomised trials are warranted to draw more definitive conclusions regarding the effects of elemental nutrition in maintaining remission in CD.

Abstract
Inflammatory bowel disease (IBD), which primarily includes Crohn's disease and ulcerative colitis, involves chronic inflammation of the gastrointestinal tract. The mechanisms of IBD pathogenesis are not well understood at this time, but likely involve an interaction between genetic, gut microbial, immune, and environmental factors. Emerging epidemiologic studies have suggested a relationship between specific dietary nutrients as an environmental factor and IBD risk. Clinical trials have also shown oral diets to have variable efficacy in affecting clinical outcomes for IBD. This review discusses the key studies that evaluated the use of various oral diets as well as nutrition support in the management of IBD.

Abstract
The evolving understanding of the role of the microbiome and environmental factors in the pathogenesis of inflammatory bowel disease makes diet an interesting and potentially powerful tool in the treatment of disease. However, at this time, evidence is limited but anecdotal reports of success abound. There is a bewildering array of new diets being tried by patients in an attempt to control diseases. This review attempts to summarize the most common diets for the treating physician.

Abstract
BACKGROUND A limited body of research suggests that ongoing maintenance enteral nutrition (MEN) can be beneficial in maintaining disease remission in Crohn's Disease (CD). We aimed to assess how achievable MEN is and whether it helps to prolong remission. METHODS Patients newly diagnosed with CD in 2010 and 2011 who commenced exclusive enteral nutrition (EEN) for 8 weeks were followed up for a year post diagnosis. All patients who took EEN were encouraged to continue MEN post EEN. Data on azathioprine use was also collected. Categorical variables were compared using chi-square/Fischer's exact test. Medians were expressed along with complete data ranges. RESULTS 59 patients (34 male, median age 11.07 years, range 2.5-16.33 years) were identified. 11/59 (18%) had a poor response to EEN and were switched to steroids. 48/59 patients completed 8 weeks EEN and achieved clinical remission/response. 46/48 patients received Modulen IBD®, 29/48 (60%) consumed EEN orally and 19/48 (40%) via NGT. 15/48 (31%) patients were able to continue MEN post EEN completion. MEN was consumed for a mean of 10.8 months (range 4-14 months). 14/15 patients drank MEN and 1/15 had MEN via NGT. Remission rates at 1 year in patients continuing MEN were 60% (9/15) compared to 15% (2/13) in patients taking no treatment (p = 0.001) and 65% (13/20) in patients taking azathioprine (p = 0.14). CONCLUSION A sub group of patients can continue MEN as a maintenance treatment and this seems a useful strategy, especially in those who are not commencing azathioprine.

Abstract
Oxidative stress is thought to play a key role in the development of intestinal damage in inflammatory bowel disease (IBD), because of its primary involvement in intestinal cells' aberrant immune and inflammatory responses to dietary antigens and to the commensal bacteria. During the active disease phase, activated leukocytes generate not only a wide spectrum of pro-inflammatory cytokines, but also excess oxidative reactions, which markedly alter the redox equilibrium within the gut mucosa, and maintain inflammation by inducing redox-sensitive signaling pathways and transcription factors. Moreover, several inflammatory molecules generate further oxidation products, leading to a self-sustaining and auto-amplifying vicious circle, which eventually impairs the gut barrier. The current treatment of IBD consists of long-term conventional anti-inflammatory therapy and often leads to drug refractoriness or intolerance, limiting patients' quality of life. Immune modulators or anti-tumor necrosis factor α antibodies have recently been used, but all carry the risk of significant side effects and a poor treatment response. Recent developments in molecular medicine point to the possibility of treating the oxidative stress associated with IBD, by designing a proper supplementation of specific lipids to induce local production of anti-inflammatory derivatives, as well as by developing biological therapies that target selective molecules (i.e., nuclear factor-κB, NADPH oxidase, prohibitins, or inflammasomes) involved in redox signaling. The clinical significance of oxidative stress in IBD is now becoming clear, and may soon lead to important new therapeutic options to lessen intestinal damage in this disease.

Abstract
BACKGROUND & AIMS Malnutrition is common in inflammatory bowel diseases (IBD), mainly in Crohn's disease (CD) because the small bowel is primarily affected. We reviewed the literature to highlight the importance of proper nutrition management. METHODS A PubMed search was performed for English-language publications from 1999 through 2012. Manuscripts comparing nutritional approaches for IBD patients were selected. RESULTS We identified 2025 manuscripts: six meta-analyses, 170 clinical-trials, 692 reviews. The study findings are discordant. In adult CD, enteral nutrition plays a supportive role, steroid therapy remaining the first choice treatment. In CD children enteral nutrition may represent the primary therapy. As regards parenteral nutrition, there are no large randomized studies, although mild improvements in morbidity have been described as a result of parenteral nutrition in malnourished surgical IBD patients. Specific micronutrient deficiencies are common in IBD. A number of factors may contribute to micronutrient deficiencies, and these include: dietary restriction, disease activity and surgery. The possible therapeutic roles of omega-3 fatty-acids, probiotics and prebiotics have been studied, but the results are still preliminary. CONCLUSION Protein-energy malnutrition and micronutrient depletion are clinical concerns in IBD patients. Enteral nutrition, parenteral nutrition and micronutrient supplementation are cornerstone of the multidisciplinary management of IBD patients.

Abstract
PURPOSE OF REVIEW Diet is known to have a major role in the expression of inflammatory bowel disease (IBD). The role of dietary interventions and enteral nutrition in the management of IBD remains unelucidated. This study was to review the current evidence for dietary risk factors for the development of IBD and the efficacies of dietary and enteral interventions. RECENT FINDINGS High dietary intakes of total fats, polyunsaturated fatty acids, omega-6 fatty acids, and meat are associated with an increased risk of Crohn's disease and ulcerative colitis. Further prospective studies are required to confirm these observations. Among various dietary interventions, none has shown striking efficacy. Meta-analyses have shown enteral nutrition to be inferior to corticosteroids in adults with active Crohn's disease. However, in children, a meta-analysis has shown no significant difference in the remission rates between enteral nutrition and corticosteroid therapy. Although the evidence level is not striking, enteral nutrition may be useful for maintaining remission in patients with quiescent Crohn's disease. SUMMARY Dietary risk factors for IBD and the therapeutic benefit of dietary and enteral interventions need to be confirmed by further well designed studies in large cohorts of patients.

Abstract
Diarrhoea is a common manifestation of Crohn's disease (CD). We advocate an evidence-based approach to treat the underlying disease and reduce symptoms. This article reviews disease grading systems, current concepts in medical therapy, and other treatments that may become available in the future. While some drug classes (e.g. salicylates, immunomodulators) have been studied for many decades, newer approaches including anti-TNF monoclonal antibodies (biologics), and gut selective agents are changing the paradigm we use to treat this debilitating condition.
