Enteral Nutrition in Adult Crohn’s Disease: Toward a Paradigm Shift
Nutrients, 2019
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 adul...

Exclusive enteral nutrition (EEN) is recommended as a first-line therapy to induce remission of Crohn’s disease (CD) and is considered as effective as corticosteroid treatment. However, the dietary restriction causes lack of adherence and poor tolerance to the therapy. Partial enteral nutrition (PEN), which allows for the ingestion of some food, could be a better tolerated alternative, but it is unknown whether it is as effective at inducing CD remission as EEN. The aim of this systematic review is to analyze the available evidence on PEN as a remission induction therapy in CD. A literature search was conducted using the MEDLINE (via PUBMED) and Cochrane Library databases following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Clinical trials in pediatric and adult patients were included. The risk of bias was assessed following the Cochrane Collaboration methodology. The selected studies showed variable but high response rates to PEN and...

Inflammatory bowel disease (IBD) is a chronic disease mediated by the immune system and is characterized by inflammation of the gastrointestinal tract. One of the possible treatments for this pathology is a change in the type of diet, of which enteral nutrition (EN) is one. This study is to understand how the use of EN can affect the adult population diagnosed with IBD. We conducted a systematic review, meta-analysis, and a meta-regression. On the different databases (MEDLINE, Scopus, Cochrane, LILACS, CINAHL, WOS), we found 363 registers with an accuracy of 12% (44 registers). After a full-text review, only 30 research studies were selected for qualitative synthesis and 11 for meta-analysis and meta-regression. The variables used were Crohn's disease activity index (CDAI), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR). EN has been shown to have efficacy for the treatment of Crohn's disease and is compatible with other medicines. As for the CDAI or rates of remission, there were no differences between enteral and parenteral nutrition. Polymeric formulas have shown better results with respect to the CRP. The long-term treatment could dilute the good CDAI results that are obtained at the start of the EN treatment.

Background/Aims: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India.Methods: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response.Results: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P= 0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P= 0.001), respectively...

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. 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. 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 fou...

Recently, the role of nutrition in the management of Crohn's disease (CD) is of increasing interest and the exploration of novel nutritional interventions to improve longterm management of the disease is challenging. So far, the majority of the studies on the role of exclusive enteral nutrition (EEN) in CD are conducted in the pediatric population and have highlighted the efficacy of EEN for achieving mucosal healing. This implicates that a similar approach would be beneficial in adult patients. However, the evidence for EEN in adults is heterogeneous, with meta-analyses reporting it as inferior to steroids while growing data demonstrate improvement in complicated CD. Currently, EEN is less used in adult patients with IBD. Indeed, the lack of palatability of enteral formula leads to difficulties in acceptance and compliance. The search for more tolerable and still effective diets has become an intense area of research aiming to explore the potential role of diet to control inflammation in patients with CD. Thus, this narrative review provides the state-of-the-art on the use of EEN treatment in CD and highlights the perceived barriers to its implementation in adult CD patients.

Thirty two patients with active Crohn's disease were included in a controlled randomised trial to determine the efficacy and safety of polymeric enteral nutrition compared with steroids, to achieve and maintain clinical remission. The polymeric diet was administered through a fine bore nasogastric tube by continuous, pump assisted infusion (2800 (SEM 120) kcal/day). The steroid group received 1 mg/kg/day ofprednisone. Both treatments were effective in inducing clinical remission: 15 of the 17 patients given steroids and 12 ofthe 15 patients assigned to the polymeric diet went into clinical remission (defined by a Van Hees index <120) within four weeks of treatment. The percentage reduction of the Van Hees index was 34*8 (4.9)% for steroids and 32 3 (5)% for enteral nutrition (mean difference 2-5%; 95% CI -11-8% to +16-8%). Mean time elapsed to achieve remission was similar in both groups (2.0 (1) v 2-4 (1.2) weeks). Tolerance of the enteral diet was excellent. Four patients in the steroid group had mild complications attributable to this treatment. Ten patients (66.6%) in the steroid group and five (41.6%) in the enteral nutrition group relapsed within a year of discharge, but no differences were found in the cumulative probability of relapse during the follow up period. These results suggest that polymeric enteral nutrition is as safe and effective as steroids in inducing short term remission in active Crohn's disease.
