Dietary intake and nutritional status in patients with newly diagnosed inflammatory bowel disease: insights from the IBSEN III study. Scand J Gastroenterol 2024; 59:652-660. [PMID: 38356408 DOI: 10.1080/00365521.2024.2313056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 01/25/2024] [Indexed: 02/16/2024]
Abstract
BACKGROUND Dietary recommendations in inflammatory bowel disease (IBD) are inconclusive, and patients may follow restrictive diets with increased risk of malnutrition. The aim of this study was to compare dietary intakes and nutritional status in men and women with newly diagnosed IBD with a general population sample, and to investigate whether intakes were in line with the Nordic Nutrition Recommendations. METHODS This was a cross-sectional study including adults≥ 40 years with IBD from the Inflammatory Bowel Disease in South-Eastern Norway (IBSEN) III cohort study. A validated food frequency questionnaire (FFQ) was used in dietary data collection, and a sample from the seventh survey of the Tromsø Study was included as a comparison group. RESULTS A total of 227 men and women with IBD were included. IBD patients had higher intake of grain products, sweetened beverages, energy, fat and polyunsaturated fat (PUFA), but lower intake of dairy products, alcohol and iodine compared to adults from the comparison sample (p < 0.01). Intakes of saturated fat and carbohydrates in both genders, and vitamin D in women were not within recommended levels. Anemia and hypoalbuminemia were more prevalent in IBD patients than in the comparison sample. CONCLUSIONS Dietary intakes in newly diagnosed IBD patients were mostly in line with Nordic Nutrition Recommendations. Higher proportion of IBD patients exceeded recommended allowances of fat and added sugar than the comparison sample. Insufficient micronutrient intake, anemia and hypoalbuminemia are present challenges in IBD patients that require monitoring.

Identifying metabolic shifts in Crohn's disease using' omics-driven contextualized computational metabolic network models. Sci Rep 2023; 13:203. [PMID: 36604447 PMCID: PMC9814625 DOI: 10.1038/s41598-022-26816-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 12/20/2022] [Indexed: 01/06/2023] Open
Abstract
Crohn's disease (CD) is a chronic inflammatory disease of the gastrointestinal tract. A clear gap in our existing CD diagnostics and current disease management approaches is the lack of highly specific biomarkers that can be used to streamline or personalize disease management. Comprehensive profiling of metabolites holds promise; however, these high-dimensional profiles need to be reduced to have relevance in the context of CD. Machine learning approaches are optimally suited to bridge this gap in knowledge by contextualizing the metabolic alterations in CD using genome-scale metabolic network reconstructions. Our work presents a framework for studying altered metabolic reactions between patients with CD and controls using publicly available transcriptomic data and existing gene-driven metabolic network reconstructions. Additionally, we apply the same methods to patient-derived ileal enteroids to explore the utility of using this experimental in vitro platform for studying CD. Furthermore, we have piloted an untargeted metabolomics approach as a proof-of-concept validation strategy in human ileal mucosal tissue. These findings suggest that in silico metabolic modeling can potentially identify pathways of clinical relevance in CD, paving the way for the future discovery of novel diagnostic biomarkers and therapeutic targets.

Aliment Pharmacol Ther 2021; 54:368-387. [PMID: 34228817 DOI: 10.1111/apt.16465] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 09/30/2020] [Accepted: 05/20/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Fatigue is the inability to achieve or maintain an expected work output resulting from central or peripheral mechanisms. The prevalence of inflammatory bowel disease (IBD) fatigue can reach 86% in active disease, persisting in 50%-52% of patients with mild to inactive disease. Fatigue is the commonest reason for work absence in IBD, and patients often report fatigue burden to be greater than that of primary disease symptoms. Relatively few evidence-based treatment options exist, and the aetiology is poorly understood. AIM To review the available data and suggest a possible aetiology of IBD fatigue and to consider the efficacy of existing management strategies and highlight potential future interventions. METHODS We reviewed fatigue-related literature in IBD using PubMed database. RESULTS Disease related factors such as inflammation and pharmacological treatments negatively impact skeletal muscle and brain physiology, likely contributing to fatigue symptoms. Secondary factors such as malnutrition, anaemia, sleep disturbance and psychological comorbidity are potential determinants. Immune profile, faecal microbiota composition and physical fitness differ significantly between fatigued and non-fatigued patients, suggesting these may be aetiological factors. Solution-focused therapy, high-dosage thiamine supplementation and biological therapy may reduce fatigue perception in IBD. The effect of physical activity interventions is inconclusive. CONCLUSIONS A multimodal approach is likely required to treat IBD fatigue. Established reversible factors like anaemia, micronutrient deficiencies and active disease should initially be resolved. Psychosocial intervention shows potential efficacy in reducing fatigue perception in quiescent disease. Restoring physical deconditioning by exercise training intervention may further improve fatigue burden.

Abstract
The purpose of this article is to provide an updated review of the definition, prevalence, causes, and clinical management of malnutrition in inflammatory bowel disease (IBD). Prevalence of malnutrition in IBD is estimated to be between 6.1% and 69.7% depending on the definition used, the type of IBD, the clinical setting, and whether the IBD is active or in remission. Whereas older definitions of malnutrition have been found to be correlated with mortality and length of hospital stay, the more recent European Society for Clinical Nutrition and Metabolism (ESPEN) 2015 and the Global Leadership Initiative on Malnutrition (GLIM) definitions provide significantly different prevalence estimates of malnutrition when applied to the same patient population, and further work is needed to validate these two definitions against clinical outcomes. In patients with IBD with identified malnutrition, oral nutrition supplementation, enteral nutrition, or parenteral nutrition should be started. In malnourished patients with Crohn's disease undergoing surgery, preoperative enteral nutrition has been demonstrated to reduce the rate of postoperative complications. Overall, patients with IBD are at significant risk for malnutrition and should be screened for malnutrition by using a validated screening tool. The management of malnutrition in IBD is complex, and studies are often limited in their size or their ability to demonstrate an improvement in clinical outcomes based on specific nutrition-related interventions. Future studies particularly regarding the validation of new screening tools and perioperative management of malnutrition may provide insight into the standardization of diagnosis and management of malnutrition in IBD.

New Predictive Equations for Estimating Resting Energy Expenditure in Adults With Crohn's Disease. JPEN J Parenter Enteral Nutr 2020; 44:1021-1028. [PMID: 32010994 PMCID: PMC7496798 DOI: 10.1002/jpen.1790] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 12/09/2019] [Accepted: 01/06/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Increased resting energy expenditure (REE) has been hypothesized to be a potential cause of weight loss in individuals with Crohn's disease (CD). This study aimed to develop and validate new predictive equations for estimating REE in adults with CD. METHODS Adults, ages 18-65 years, with CD were recruited. Anthropometry, indirect calorimetry, and bioimpedance analysis were performed in all patients. Disease activity was assessed by Crohn's Disease Activity Index. The new predictive equations were generated using different regression models. Prediction accuracy of the new equations was assessed and compared with the most commonly used equations. RESULTS A total of 270 CD patients (159 males, 111 females) were included and randomly assigned to the calibration (n = 180) and validation groups (n = 90). REE was directly correlated with weight and bioimpedance index, whereas the relation with both age and disease activity was inverse. The new equations were suitable for estimating REE at population level (bias: -0.2 and -0.3, respectively). Individual accuracy was good in both models (≥80%, respectively), especially in females; and similar results were shown by some of the selected equations. But, when accuracy was set within ±5%, the new equations gave the highest prediction. CONCLUSION The new, disease-specific, equations for predicting REE in individuals with CD give a good prediction accuracy as far as those proposed in the literature for the general population. However, the new ones performed better at the individual level. Further studies are needed to verify the reliability and usefulness of these new equations.

Abstract
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.

Abstract
INTRODUCTION These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries. METHODOLOGY The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. RESULTS Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation. CONCLUSIONS Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.

Abstract
BACKGROUND AND AIMS A growing body of evidence supports the need for detailed attention to nutrition and diet in children with inflammatory bowel disease (IBD). We aimed to define the steps in instituting dietary or nutritional management in light of the current evidence and to offer a useful and practical guide to physicians and dieticians involved in the care of pediatric IBD patients. METHODS A group of 20 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to Nutrition Committee of the European Society of Pediatric Gastroenterology, Hepatology and Nutrition Porto, IBD Interest, and Nutrition Committee. A list of 41 predefined questions was addressed by working subgroups based on a systematic review of the literature. RESULTS A total of 53 formal recommendations and 47 practice points were endorsed with a consensus rate of at least 80% on the following topics: nutritional assessment; macronutrients needs; trace elements, minerals, and vitamins; nutrition as a primary therapy of pediatric IBD; probiotics and prebiotics; specific dietary restrictions; and dietary compounds and the risk of IBD. CONCLUSIONS This position paper represents a useful guide to help the clinicians in the management of nutrition issues in children with IBD.

Abstract
Twenty-five percent of inflammatory bowel disease (IBD) diagnoses present in childhood, with Crohn's disease (CD) being the most common type. Many children have poor nutrition status at presentation of the disease, which may worsen during the clinical course, with a significant number of children having impaired linear growth. The cause of this poor nutrition status is complex, and contributing factors include inadequate intake, malabsorption, altered energy demands, and losses through stool, particularly in colitis. The principal aim of medical management is to induce disease remission, with minimal side effects, thereby enabling normal growth and development. This must include active consideration of the nutrition needs of such children and how they may be best met. However, our understanding of the manner in which the disease process affects the energy demands of children with CD or how poor nutrition, in turn, may affect the disease course is limited. This may constrain the efficacy and effectiveness of standard therapeutic approaches to care. This review explores the many factors of relevance in the delivery of nutrition support to children with inflammatory bowel disease, and explores the role of exclusive enteral nutrition as a corticosteroid-sparing strategy to induce remission in children with active Crohn's disease.

Abstract
BACKGROUND Malnutrition is a common sequela of Crohn's disease (CD) and may result in reduced skeletal muscle function and growth retardation. Energy requirements of parenterally fed hospitalized pediatric patients with active CD were measured using indirect calorimetry, to assess whether Food Agriculture Organization (FAO)/World Health Organization (WHO)/United Nations University (UNU) equations provide appropriate estimations of energy requirements in this patient population. METHODS Twenty hospitalized patients with active CD fed exclusively via parenteral nutrition (PN) were investigated. A chart review and patient interviews were conducted to assess disease duration, location, laboratory parameters, and symptomology associated with CD. Disease severity was quantified using the Pediatric Crohn's Disease Activity Index. Each subject underwent indirect calorimetry, bioelectrical impedance analysis, and anthropometric assessment once the ordered PN met estimated macronutrient requirements of each patient (predicted resting energy expenditure x1.3). Predicted resting energy expenditure (REE) was determined using the FAO/WHO/UNU equations. RESULTS REE showed a strong correlation with predicted REE (r(2) = .73, p < .01). CONCLUSIONS Measured REE did not significantly differ from predicted resting energy requirements. This indicates that REE for the parenterally fed pediatric patients with CD can be accurately predicted using the FAO/WHO/UNU equations.

Abstract
BACKGROUND Body composition is poorly studied in inflammatory bowel disease (IBD). Sarcopenia describes a loss of muscle mass and strength. AIM To assess the prevalence of low lean mass (LM), sarcopenia and associated morbidity in an adult IBD cohort. METHODS Cross-sectional data were gathered on pre-menopausal 18- to 50-year-old patients with IBD. Whole-body dual-energy X-ray absorptiometry, anthropometric assessment and grip strength were performed. Low LM was defined as ≥1 s.d. below the population mean for appendicular skeletal muscle index [ASMI (kg)/height (m)²], and sarcopenia as both ASMI and grip strength ≥1 s.d. below population mean. Multivariate regression analyses were performed. RESULTS Of 137 participants (median age 31 years, BMI 24.8 kg/m(2) ), 56% were male and 69% had Crohn's disease (CD). Low LM and sarcopenia were observed in 21% and 12% of patients, respectively, and osteopenia/osteoporosis in 38% of patients (mean lumbar spine t-score -0.3 ± s.d. 1.1). Grip strength predicted low LM and sarcopenia better than did body mass index (BMI) (OR 4.8 vs. OR 0.7 for low-LM, P < 0.05 both). Normal BMI was falsely reassuring in 72% and 76% of patients with low ASMI and sarcopenia, respectively. Low LM and sarcopenia (OR = 3.6, P = 0.03; OR = 6.3, P = 0.02; respectively), but not BMI nor fat mass, predicted osteopenia/osteoporosis. CONCLUSIONS Low lean mass and sarcopenia are common in patients with IBD, and important to recognise as they predict osteopenia/osteoporosis. Grip strength testing should be incorporated into routine clinical practice to detect low lean mass deficits, which may go unrecognised using BMI alone.

Abstract
This study aimed to compare the nutritional status and energy expenditure of hospitalized patients with Crohn’s disease (CD) and those with ulcerative colitis (UC). Twenty-two hospitalized patients with CD and 18 patients with UC were enrolled in this study. We analyzed nutritional status upon admission by using nutritional screening tools including subjective global assessment, malnutrition universal screening tool, and laboratory tests. We measured resting energy expenditure (mREE) of the patients with indirect calorimetry and predicted resting energy expenditure (pREE) was calculated by using the Harris-Benedict equation. Results presented here indicate no significant difference in nutritional parameters and energy metabolism between CD and UC patients. In UC patients, a significant correlation was observed between mREE/body weight and disease activity detected by the Lichtiger and Seo indices. However, there was no correlation between mREE/body weight and Crohn’s disease activity index in CD patients. Inflammatory cytokine interleukin-6 levels correlated with mREE/pREE in CD and UC patients while tumor necrosis factor-α was not. In conclusion, energy expenditure significantly correlated with disease activity in UC patients but not in CD patients. These results indicate that establishing daily energy requirements based on disease activity of UC is imperative for improving the nutritional status of patients.

Abstract
We investigated the changes in energy expenditure during induction therapy in patients with severe or moderate ulcerative colitis. Thirteen patients (10 men, 3 women; mean age, 36.5 years) with ulcerative colitis admitted to the Shiga University Hospital were enrolled in this study. We measured the resting energy expenditure and respiratory quotients of these patients before and after induction therapy with indirect calorimetry. We analyzed the changes of nutritional status and serum inflammatory cytokine levels and also evaluated the relationship between energy metabolism and disease activity by using the Seo index and Lichtiger index. The resting energy expenditure was 26.3 ± 3.8 kcal/kg/day in the active stage and significantly decreased to 23.5 ± 2.4 kcal/kg/day after induction therapy (p<0.01). The resting energy expenditure changed in parallel with the disease activity index and C-reactive protein and inflammatory cytokine levels. The respiratory quotient significantly increased after induction therapy. Thus, moderate to severe ulcerative colitis patients had a hyper-metabolic status, and the energy metabolism of these patients significantly changed after induction therapy. Therefore, we recommend that nutritional management with 30–34 kcal/kg/day (calculated as measured resting energy expenditure × activity factor, 1.3) may be optimal for hospitalized ulcerative colitis patients.

Abstract
We investigated the effects of treatment with antibodies against tumor necrosis factor (TNF)-α on energy metabolism, nutritional status, serum cytokine levels in patients with Crohn’s disease (CD). Twelve patients were enrolled. Resting energy expenditure (REE) levels were measured by indirect calorimetry. Crohn’s disease activity index (CDAI) significantly decreased after treatment with anti-TNF-α therapy. Anti-TNF-α therapy did not affect REE, but respiratory quotient (RQ) significantly increased after treatment. Serum interleukin-6 levels were significantly decreased and RQ were significantly increased in high REE (≥25 kcal/kg/day) group as compared to low REE (<25 kcal/kg/day) group. In conclusion, high REE value on admission is a predictive factor for good response to treatment with anti-TNF-α antibodies in active CD patients.

Abstract
BACKGROUND There is a paucity of data on body composition in patients with inflammatory bowel disease (IBD). Alterations of fat and muscle may affect bone health, muscle performance, quality of life (QoL) and overall morbidity. AIMS To systematically review the literature on body composition in adults with IBD, and to discuss potential contributory factors and associations. METHODS A systematic search was performed in July 2012 of OVID SP MEDLINE, OVID EMBASE and National Library of Medicine's PubMed Central Medline (Limitations: English, humans, from 1992). A total of 19 articles comparing body composition in patients with IBD with healthy age- and sex-matched control populations were included in the primary analysis. RESULTS A total of 631 patients with Crohn's disease (CD) and 295 with ulcerative colitis (UC), mean age 37.1 (s.d. ± 9.2) years; 485 (52%) female, were reported upon. Data were heterogeneous and methodology varied. Compared with controls, a statistically significant reduction in body mass index (BMI) was reported in 37% of CD and 20% of UC patients; reduced fat-free mass in 28% CD and 13% UC patients, and reduced fat mass in 31% CD and 13% UC patients. There was no consistent association between body composition and disease activity, duration, extent or therapies. BMI did not accurately predict body composition. CONCLUSIONS Current data, although heterogeneous, suggest that many patients with IBD are affected by aberrations in fat and lean mass, which may not be detected during routine clinical assessment. The prevalence and impact of altered body composition amongst this population warrant further investigation.

Abstract
BACKGROUND AND AIMS Increased resting energy expenditure (REE) unmatched by dietary intake is implicated as a cause of poor nutrition in childhood inflammatory conditions. Adequate description of disease activity and correction of REE data for body composition are important to reach reliable conclusions about changes in REE associated with disease. The present study aimed to determine the effect of disease activity measured by clinical status, systemic and stool inflammatory markers on REE in children with Crohn disease using appropriate correction for confounding factors. METHODS Sixty children with Crohn disease were recruited from the regional paediatric gastroenterology unit and studied on 1 occasion. REE was measured by indirect calorimetry. Fat-free mass (FFM) was estimated by skinfold thickness. Disease activity was measured using systemic (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR]) and faecal markers of inflammation (lactoferrin, calprotectin) and clinical scores (Paediatric Crohn Disease Activity Index). RESULTS Using a multiple regression model, there was no significant change in REE from active or inactive disease (β = 0.03, P = 0.7) nor from CRP (β = -0.05, P = 0.52), ESR (β = -0.07, P = 0.43), faecal calprotectin (β = -0.07, P = 0.38), and faecal lactoferrin (β = 0.01, P = 0.88). REE/kg FFM was not associated with the Paediatric Crohn Disease Activity Index (r = 0.1, P = 0.44), CRP (r = -0.3, P = 0.84) or ESR (r = 0.12, P = 0.4), faecal calprotectin (r = 0.04, P = 0.97), or faecal lactoferrin (r = 0.02, P = 0.87). CONCLUSIONS REE corrected for physiologically relevant confounders is not associated with degree of disease activity using clinical tools or systemic and local inflammatory markers, and therefore is an unlikely mechanism for poor nutritional state.

Abstract
RACIONAL: Pacientes com doença inflamatória intestinal podem apresentar deficiências nutricionais. OBJETIVO: Verificar a adequação da ingestão alimentar de pacientes com doença de Crohn e retocolite ulcerativa inespecífica. MÉTODOS: Para avaliação da ingestão alimentar de 55 pacientes, 28 com doença de Crohn e 27 com retocolite ulcerativa atendidos em ambulatório de gastroenterologia, utilizou-se o Recordatório Alimentar de 24 Horas e o Questionário de Frequência Alimentar. A atividade inflamatória da doença foi avaliada pelos níveis séricos de proteína C reativa e o Índice de Harvey e Bradshaw. Para comparação de médias foi usado o teste t não pareado e, para as médias não paramétricas, o teste de Mann-Whitney, considerando nível de significância valor de p<0,05. RESULTADOS: Os pacientes tinham idade entre 19 e 63 anos e tempo de diagnóstico de 7,9 anos (1 a 22). De acordo com a ingestão alimentar identificou-se deficiência na ingestão de energia, fibras, ferro, potássio, sódio, magnésio, cálcio, menadiona, riboflavina, niacina, folato, ácido pantotênico, tocoferol e colecalciferol na doença de Crohn e na retocolite ulcerativa em atividade ou em remissão. A ingestão de legumes, frutas, laticínios e feijão foi baixa, e a de doces e gorduras foi maior que as recomendações. CONCLUSÃO: Houve deficiência na ingestão alimentar tanto na doença de Crohn como na retocolite ulcerativa, em atividade e em remissão. Essas deficiências podem afetar negativamente o curso da doença e justificam a necessidade de intervenção nutricional com esses pacientes.

Abstract
Patients with inflammatory bowel disease (IBD) often question their doctors about diet. The objectives of this article are to provide clinicians with existing dietary advice by presenting the dietary information proposed by medical societies in the form of clinical practice guidelines as it relates to IBD; listing dietary guidelines from patient-centered IBD-related organizations; and creating a new 'global practice guideline' that attempts to consolidate the existing information regarding diet and IBD. The dietary suggestions derived from sources found in this article include nutritional deficiency screening, avoiding foods that worsen symptoms, eating smaller meals at more frequent intervals, drinking adequate fluids, avoiding caffeine and alcohol, taking vitamin/mineral supplementation, eliminating dairy if lactose intolerant, limiting excess fat, reducing carbohydrates and reducing high-fiber foods during flares. Mixed advice exists regarding probiotics. Enteral nutrition is recommended for Crohn's disease patients in Japan, which differs from practices in the USA.

Abstract
BACKGROUND & AIMS Pediatric Crohn's disease (CD) is associated with growth, lean mass (LM), and fat mass (FM) deficits. This study assessed and identified determinants of changes in height and body composition in children with CD following. METHODS Whole-body LM and FM were assessed using dual-energy x-ray absorptiometry in 78 CD subjects at diagnosis, 6, 12, and a median of 43 months (range, 24-63) later. Race- and sex-specific Z scores for lean mass (LM-ht-Z) and fat mass (FM-ht-Z) relative to height were derived using reference data in >900 controls. Serum cytokines and growth factors were measured, and quasi-least squares regression was used to identify determinants of changes in height and body composition. RESULTS LM-ht-Z and FM-ht-Z (both P<.005) improved significantly after diagnosis; however, female patients had persistent LM deficits vs controls (-0.50+/-1.02, P<.05). Serum interleukin-6, tumor necrosis factor-alpha, and lipopolysaccharide binding protein decreased significantly (all P<.001). Greater increases in LM-ht-Z were associated with infliximab therapy (P<.05), increases in albumin (P<.001) and decreases in erythrocyte sedimentation rate (P<.05), interleukin-6 (P<.005), and lipopolysaccharide binding protein (P<.05). Greater increases in FM-ht-Z were associated with glucocorticoid, methotrexate, and infliximab therapy, and increases in albumin (P<.05) and growth hormone binding protein (P<.05). Overall, height-Z did not improve; however, greater increases in insulin-like growth factor-1 (P<.05) and decreases in tumor necrosis factor-alpha (P<.05), interleukin-6 (P<.05), and lipopolysaccharide binding protein (P<.05) levels were associated with increases in height-Z. CONCLUSIONS Immune-mediated mechanisms contribute to growth and body composition deficits in CD. Therapies should target these deficits.

Abstract
BACKGROUND Fatigue is common, disabling yet underappreciated, in patients with chronic diseases, including inflammatory bowel disease (IBD). AIMS To examine the literature and determine the prevalence and patterns of fatigue in IBD patients, to identify opportunities and directions for future research in this area. METHODS A systematic review using PubMed and Ovid Medline databases was conducted using search terms 'fatigue', 'Crohn', 'colitis' and 'inflammatory bowel disease'. A review of fatigue in other similar chronic diseases was also performed. RESULTS Ten studies were found to include data on fatigue in IBD patients; all were conducted between 1999 and 2009. However, only one study (in children) measured fatigue in IBD patients as a primary outcome. In patients in remission, the prevalence of fatigue in IBD patients ranges from 41 to 48%. Data are sparse and conflicting on whether fatigue severity is proportional to disease severity/activity. CONCLUSIONS Despite the clinical reality of fatigue, there are few published studies examining fatigue in IBD as a primary outcome. More data are needed on the prevalence, correlation between disease activity and fatigue severity, and putative pathogenic pathways involved in fatigue pathogenesis, before ultimately elucidating targeted therapies for fatigue in IBD patients.

Abstract
We investigated the energy expenditure in hospitalized patients with severe or moderate ulcerative colitis (UC), and compared them to healthy controls. Thirteen patients (5 women and 8 men; mean age 31.8 years; mean BMI 19.0 kg/m2) and 10 healthy volunteers were enrolled in this study. The resting energy expenditure (mREE) levels were determined by indirect calorimetry. The mREEs of the UC patients were significantly higher than those of healthy controls (26.4 ± 3.6 vs 21.8 ± 1.7 kcal/kg/day), although the mREEs of the UC patients were almost the same as the predicted REEs (pREEs) calculated by the Harris-Benedict equation (26.4 ± 2.4 kcal/kg/day vs 26.5 ± 2.6 kcal/kg/day). The mREE/pREE ratio, which reflects stress, was 1.0 ± 0.15. In the UC patients, a significant correlation was observed between the mREEs and the clinical activity index. In conclusion, UC patients showed a hyper-metabolic status as evaluated by their mREE/body weight. Energy expenditure was significantly correlated with disease activity. From our observations, we recommend that nutritional management with more than 30–35 kcal/ideal body weight/day (calculated by the mREE × activity factor) may be optimal for active severe or moderate ulcerative colitis.

Abstract
Prescription drugs and surgery are two common medical therapies for Crohn's disease (CD), an inflammatory bowel disease that affects the GI tract. Unfortunately, certain drugs can cause serious side effects, and surgeries must often be repeated. No diet has been established to alleviate the pain and suffering of CD patients. This is curious given the fact that a higher prevalence of food sensitivities exist in this population of patients, and enteral nutrition is not only the first-line of therapy in Japan, but a known research method used to place the majority of CD patients into remission. Although not all patients respond equally to diet, many simply remove symptom-provoking foods, such as dairy, wheat, corn and certain fruits and vegetables. We suggest assisting these patients in their self-assessment of irritating and symptom-provoking foods by educating them in the use of a food-symptom diary followed by a customized elimination diet trialed for 2-4 weeks to determine if there is any benefit to the individual patient.

Abstract
We investigated energy expenditure in hospitalized patients with Crohn’s disease (CD), and determined optimal energy requirements for nutritional therapy. Sixteen patients (5 women and 11 men, mean age 36 year old, mean BMI 18.7 kg/m2) and 8 healthy volunteers were enrolled in this study. Measured resting energy expenditure (mREE) levels were determined by indirect calorimetry. The mREEs in CD patients were significantly higher than those of healthy controls (24.4 ± 2.4 kcal/kg/day vs 21.3 ± 1.7 kcal/kg/day). However, mREEs in CD patients were significantly lower than predicted REEs (pREEs) calculated by the Harris-Benedict equation (26.4 ± 2.5 kcal/kg/day). Furthermore, mREE/pREE values were lower in undernourished patients than in well-nourished patients. CD patients had hyper-metabolic statuses evaluated by mREE/body weight, but increased energy expenditure did not contribute to weight loss in these patients. In conclusion, nutritional therapy with 25–30 kcal/ideal body weight/day (calculated by mREE × active factor) may be optimal for active CD patients, while higher energy intake values pose the risk of overfeeding.

Abstract
BACKGROUND AND AIMS Exclusive enteral nutrition is used as primary therapy in Crohn's disease. Nutrition support is frequently required in children with both Crohn's disease and Ulcerative Colitis when acutely unwell and during periods of recovery. There is considerable controversy about nutritional needs during phases of active and inactive disease. It is, for example, often assumed that in acute illness a child requires increased nutritional support however the precise relationship between illness severity and energy expenditure is uncertain. This study explores the relationship between disease activity and resting energy expenditure (REE) in children with inflammatory bowel disease. METHODS Patients were recruited from the regional paediatric gastroenterology unit at Southampton University Hospitals NHS Trust. Disease activity was assessed using standard scoring systems (Paediatric Crohn's Disease Activity Index; Simple Colitis Activity Index) and biochemical markers of inflammation (C-Reactive Protein, CRP). Fat free mass was estimated from skinfold thickness and Bioelectrical Impedance Analysis. Resting energy expenditure was measured by indirect calorimetry. A logarithmic correction and a linear regression model were used for analysis of REE corrected for body size. RESULTS 55 children were studied; 37 (67%) with Crohn's disease and 18 (33%) with Ulcerative Colitis. Median PCDAI was 10 (range 0-60), 22 (59%) had PCDAI > or =10 (active disease). Median SCAI was 1.5 (range 0-12). Within disease groups there were strong correlations between REE/KgFFM(0.52) and disease activity; PCDAI (r -0.386, p 0.018) in Crohn's disease and SCAI (r -0.456, p 0.057) in Ulcerative Colitis. In the cohort as a whole there was no increase in REE/KgFFM(0.52) with increasing CRP (r 0.129, p 0.361). Using the regression model each mg/l increase in CRP was associated with a reduction in REE of nearly 1.5 kCal/day. CONCLUSIONS We were unable to demonstrate a significant relationship between REE and disease activity in children with inflammatory bowel disease.

Abstract
OBJECTIVE Undernutrition has been reported in 65-75% of patients with Crohn's disease. The present study aimed at identifying the relative contribution of malnutrition-causing factors in patients with Crohn's disease in remission. METHODS Sixteen patients with Crohn's disease (age 19-57 y) in remission (Crohn's Activity Disease Index < 150) were included in the study. Their weight was stable for >3 mo and they were off steroids. They all completed 3-d food records and concomitantly collected stools. Self-reported food records were analyzed and energy content in stools was determined by a direct bomb calorimeter. Resting energy expenditure (REE) was studied by indirect calorimetry and body composition by dual-energy X-ray absorptiometry. The study cohort was divided into two groups, with a body mass index (BMI) equal to 18.5 kg/m(2) serving as a cutoff point. RESULTS Subjects with lower BMIs tended to have less lean body mass (P = 0.006), less bone mineral density (P = 0.006), and lower REE (P = 0.003). No correlation was found between BMI and energy intake but the percentage of malabsorption was negatively correlated with BMI (P = 0.07). When dividing the study based on a BMI of 18.5 kg/m(2), no difference was found in caloric intake or REE between groups but subjects with lower BMIs had significant prominent malabsorption compared with the others (21.1 +/- 9.8% versus 11.7 +/- 3.5%, P = 0.015). CONCLUSION In the presence of similar energy intake, REE does not seem to contribute to lower BMI, although nutrient malabsorption is higher in malnourished patients with Crohn's disease in remission. We suggest that malabsorption be evaluated in patients with Crohn's disease who fail to gain weight during disease remission to establish their extra caloric requirements.

Abstract
AIM There is limited information on the nutrition impact of antitumor necrosis factor-alpha treatment in adult Crohn's disease (CD). This study was performed to examine the effect of a 6-month course of infliximab on enterocyte function, nutrient status, metabolism, and body composition in these patients. METHODS Seven CD patients were assessed for disease activity, enterocyte function, and body composition prior to, after 6 weeks, and after 6 months of infliximab treatment. Measurements included (1) disease activity: Inflammatory Bowel Disease Questionnaire, Harvey Bradshaw Index, and C-reactive protein; (2) enterocyte function: folate, homocysteine, vitamin B(12), citrulline, vitamin D, beta-carotene, d-xylose absorption; (3) Prognostic Inflammatory and Nutritional Index (PINI); and (4) body composition and metabolism: body mass index (BMI), fat and lean body mass, resting energy expenditure (RRE), and respiratory quotient. RESULTS Most patients had improvement in disease activity with infliximab. PINI decreased in all patients (-3.35, P = .04). Plasma folate concentration significantly increased. There was an increase in BMI, fat mass, and lean body mass. The respiratory quotient increased in most patients. Changes in citrulline level and REE were inconsistent. CONCLUSIONS Crohn's disease patients have improvements in an index that measures both inflammation and nutrition (PINI) with infliximab therapy. Increases in plasma folate suggest improvement in enterocyte function and/or increased oral intake. The increase in respiratory quotient suggests decreased lipolysis and the lack of a starvation state. It was unclear whether weight gain was predominantly fat or lean muscle mass. These finding also support the use of PINI in Crohn's patients as an overall marker of inflammation and nutrition, and as a measure of response to infliximab therapy.

Abstract
BACKGROUND Childhood Crohn's disease (CD) is associated with poor growth and decreased body mass index (BMI); however, lean mass (LM) and fat mass (FM) deficits prior to therapy have not been characterized. OBJECTIVES To quantify LM and FM in incident pediatric CD subjects and controls, and to identify determinants of LM and FM deficits. METHODS Whole body LM and FM were assessed using DXA in 78 CD subjects and 669 healthy controls, ages 5-21 yr. Gender specific z-scores for LM (LM-Ht) and FM (FM-Ht) relative to height were derived using log linear regression models in the controls. Multivariate linear regression models adjusted for potential confounders. RESULTS CD was associated with significantly lower height and BMI for age. Within CD subjects, FM-Ht and LM-Ht were significantly lower in females compared with males (FM-Ht z: -0.66+/-0.83 vs. -0.08+/-0.95, p<0.01; LM-Ht z: -1.12+/-1.12 vs. -0.57+/-0.99, p<0.05). In females, CD was associated with significantly lower LM-Ht (p<0.001) and FM-Ht (p=0.001), adjusted for age, race and Tanner stage, compared with controls. LM and FM deficits were significantly greater in older females with CD; 47% of adolescent females had LM-Ht<or=5th percentile. In non-black males, CD was also associated with lower LM-Ht (p<0.02); FM-Ht deficits were not significant. CONCLUSIONS Incident CD was associated with significant LM deficits in males and females, and FM deficits in females. Future studies are needed to identify etiologies for the age and gender differences and to evaluate therapies for these deficits.

Abstract
Undernutrition as well as specific nutrient deficiencies have been described in patients with Crohn's disease (CD), ulcerative colitis (UC) and short bowel syndrome (SBS). The present guideline gives evidence-based recommendations for the indication, application and type of formula of enteral nutrition (EN) (oral nutritional supplements (ONS) or tube feeding (TF)) in these patients. It was developed in an interdisciplinary consensus-based process in accordance with officially accepted standards and is based on all relevant publications since 1985. ONS and/or TF in addition to normal food is indicated in undernourished patients with CD or CU to improve nutritional status. In active CD EN is the first line therapy in children and should be used as sole therapy in adults mainly when treatment with corticosteroids is not feasible. No significant differences have been shown in the effects of free amino acid, peptide-based and whole protein formulae for TF. In remission ONS is recommended only in steroid dependent patients in CD. In patients with SBS TF should be introduced in the adaptation phase and should be changed with progressing adaptation to ONS in addition to normal food.

Abstract
AIM To determine the concentrations of leptin and ghrelin, which have opposite effects on appetite, energy expenditure, and weight control, in the plasma of patients with Crohn's disease (CD), which is often associated with weight loss and malnutrition. METHODS Plasma leptin and ghrelin 'concentrations were determined in 28 outpatients with CD by radioimmunoassay. Age- and sex-matched controls with and without Helicobacter pylori (H pylori) infection (28 for each) were enrolled in the study. Circulating levels of these hormones were assessed with respect to CD activity, disease localization and medical treatment. RESULTS There were no significant differences in ghrelin levels between CD patients and H pylori-negative controls. However, circulating ghrelin levels were significantly lower in H pylori-infected subjects than in CD patients and uninfected controls. Plasma leptin levels were comparable among the groups. Localization and medication profile had no significant impact on circulating ghrelin and leptin levels. CONCLUSION Apart from H pylori infection, CD itself has no significant influence on circulating ghrelin and leptin levels in the outpatients who were mostly in inactive state.

Abstract
Protein-energy malnutrition and specific nutrient deficiencies are common in inflammatory bowel diseases (IBD), more particularly in Crohn's disease. In adults, the use of artificial nutrition is indicated in the event of malnutrition, short bowel syndrome, or IBD refractory to all other treatments. In children, enteral nutrition has a place as first-line treatment to avoid side effects of corticosteroids on growth. The use, as a therapeutic tool, of specific nutrients (n-3 fatty acids, glutamine, antioxydant vitamins and minerals, TGF-beta, probiotics...) seems interesting at the pathophysiological level. Nevertheless, these nutrients are still under evaluation and there are not enough available studies to recommend them in clinical routine. A very promising solution is the use of probiotics for the treatment of refractory pouchitis.

Abstract
BACKGROUND Crohn disease (CD) in children is associated with low body mass index (BMI), poor growth, and delayed maturation; alterations in lean and fat mass, however, are poorly characterized. OBJECTIVE The objective was to quantify lean and fat mass in children and young adults with CD and in healthy control subjects, relative to height and pubertal maturation. DESIGN This cross-sectional study assessed whole-body lean and fat mass by using dual-energy X-ray absorptiometry in 104 subjects with CD and in 233 healthy control subjects aged 4-25 y. Linear regression was used to determine the effect of CD on body composition and to generate sex-specific SD scores (z scores) for lean and fat mass relative to height. RESULTS Subjects with CD had lower height-for-age and BMI-for-age z scores (P < 0.001 for both) than did control subjects. CD was associated with significant deficits in lean mass after adjustment for height, age, race, and Tanner stage (P = 0.003); deficits in fat mass were not observed. The mean (+/-SD) lean mass-for-height and fat mass-for-height z scores in the subjects with CD were -0.61 +/- 0.92 and -0.04 +/- 0.86, respectively. Within the control group, fat mass-for-height was positively correlated with lean mass-for height (r = 0.41, P < 0.0001); this association was absent in the subjects with CD. CONCLUSIONS Children and young adults with CD had significant deficits in lean mass but preserved fat mass, which is consistent with cachexia. Further research is needed to identify physical activity, nutritional, and antiinflammatory interventions to improve body composition in persons with CD.

Abstract
BACKGROUND Recent attention focused on the effect of inflammatory cytokines on intermediary metabolism contributing to the nutritional disturbances observed in acute or chronic inflammatory diseases. AIMS To examine the interactions between immune activation and nutritional parameters in adult Crohn's disease patients. PATIENTS AND METHODS We analysed anthropometric and biochemical nutritional parameters in 40 Crohn's disease patients and 26 healthy controls, and related them to inflammatory and immune markers. RESULTS Weight, body mass index, mid-arm circumference, triceps skinfold thickness, as well as albumin, transthyretin, retinol binding protein, insulin growth factor-I and Vitamin A were significantly decreased in Crohn's disease patients and negatively correlated to disease activity. By contrast, erythrocyte sedimentation rate, fibrinogen, C-reactive protein, alpha1-acylglycoprotein, soluble receptor of interleukin-2, blood neopterin, tumour necrosis factor-alpha and interleukin-1beta concentrations were significantly higher in patients and positively correlated to disease activity. Nutritional parameters and acute phase reactants were linked to tumour necrosis factor-alpha and interleukin-1beta concentrations, and markers of nutritional status were negatively correlated to positive acute phase reactants. CONCLUSIONS In Crohn's disease, inflammatory cytokines appear partly responsible for decreased nutritional status. Thus, nutritional intervention to correct nutritional (in particular protein) depletion, and/or therapeutic intervention reducing inflammation and therefore restoring adequate nutritional proteins synthesis, appears a major therapeutic goal in active Crohn's disease.

Abstract
BACKGROUND Because patients with Crohn's disease (CD) often show increased energy expenditure, nutritional deficiencies, and general fatigue, all which may persist after a flare, we hypothesized that CD could alter muscle mass and function. This study aimed to assess muscle strength and endurance in CD patients in clinical remission and the influencing factors. METHODS Forty-one outpatients (17 men and 24 women; age, 37 +/- 10 yr), in remission (CD Activity Index < 150) for > 3 months, and 25 age-matched healthy controls (10 men and 15 women; age, 37 +/- 13 yr) were evaluated. Evaluation included a sit-up test, hand-grip strength test, hand-grip endurance test, lower limb strength test, and lower limb endurance test (LE), as well as a measure of physical activity. RESULTS No significant difference was found between CD and control groups regarding weight, height, body mass index, fat mass, and fat-free mass. Strength performance was lower in CD subjects compared with controls, particularly for lower limb indexes: lower limb strength test (-24.6%, P < 0.001), LE (-25.8%, P < 0.001), and sit-up test (-25.1%, P < 0.001). Previous disease severity, disease duration, the cumulative dose of glucocorticosteroids, current inflammation, and global habitual physical activity did not affect muscle performance. A recent use of steroids improved LE. CONCLUSIONS CD patients in clinical remission have decreased muscle function that may affect their quality of life. This pattern is reflected by reduced strength and endurance indexes, particularly for lower limbs. The reasons for these changes need further study. Strength training should be assessed in these patients.

Abstract
Impairment of growth and malnutrition are significant complications of inflammatory bowel disease (IBD) in pediatric patients. Since this topic was last reviewed in these pages (), a number of studies have further explored the epidemiology and pathogenesis of these nutritional complications of IBD in an effort to provide more effective interventions to prevent the long-term consequences of chronic nutrient deficiencies in childhood. In addition, during the past 15 years, the use of selected nutrients and microorganisms (probiotics) as primary or adjunctive therapy for the treatment of IBD has become an emerging area of great interest. The following is a Clinical Report from the Nutrition and Inflammatory Bowel Disease Committees of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

Abstract
Nutrition plays an important role in the pathogenesis, treatment, and morbidity of Crohn disease. Approximately two thirds to three fourths of hospitalized patients with active disease and one fourth of outpatients with Crohn disease are malnourished. Malnutrition, which can be present even when Crohn disease is in remission, can affect growth, cellular and humoral immunity, bone density, and wound healing. Decreased nutrient intake, malabsorption, drug-nutrient interactions, anorexia, and protein-losing enteropathy can all contribute to the protein-calorie malnutrition and other specific nutrient deficiencies seen in Crohn disease. Therefore, by preventing and correcting nutrient deficiencies, nutritional therapy is an important component in the overall management of patients with Crohn disease.

Abstract
Inflammatory Bowel Diseases - ulcerative colitis and Crohn's disease- are chronic gastrointestinal inflammatory diseases of unknown etiology. Decreased oral intake, malabsorption, accelerated nutrient losses, increased requirements, and drug-nutrient interactions cause nutritional and functional deficiencies that require proper correction by nutritional therapy. The goals of the different forms of nutritional therapy are to correct nutritional disturbances and to modulate inflammatory response, thus influencing disease activity. Total parenteral nutrition has been used to correct and to prevent nutritional disturbances and to promote bowel rest during active disease, mainly in cases of digestive fistulae with high output. Its use should be reserved for patients who cannot tolerate enteral nutrition. Enteral nutrition is effective in inducing clinical remission in adults and promoting growth in children. Due to its low complication rate and lower costs, enteral nutrition should be preferred over total parenteral nutrition whenever possible. Both present equal effectiveness in primary therapy for remission of active Crohn's disease. Nutritional intervention may improve outcome in certain individuals; however, because of the costs and complications of such therapy, careful selection is warranted, especially in patients presumed to need total parenteral nutrition. Recent research has focused on the use of nutrients as primary treatment agents. Immunonutrition is an important therapeutic alternative in the management of inflammatory bowel diseases, modulating the inflammation and changing the eicosanoid synthesis profile. However, beneficial reported effects have yet to be translated into the clinical practice. The real efficacy of these and other nutrients (glutamine, short-chain fatty acids, antioxidants) still need further evaluation through prospective and randomized trials.

Abstract
OBJECTIVE Patients with Crohn's disease (CD) have increased energy expenditure and fat oxidation. Steroids, commonly used to treat flare-up of CD, induce weight gain. This study was designed to evaluate the effects of prednisone and budesonide on energy expenditure and substrate oxidation in patients with CD. METHODS Twenty-nine women with CD and 10 healthy controls were studied. Ten patients received prednisone (0.75-1.0 mg/kg/day), nine received budesonide (9 mg/ day), and 10 did not receive steroids. Resting energy expenditure and substrate oxidation were measured by indirect calorimetry in a fasting state and after a standard diet. RESULTS In the fasting state, resting energy expenditure was higher in patients without steroids than in the controls. Lipid oxidation was lower (p < 0.01) in patients with prednisone (0.46 +/- 0.39 mg/kg/min) than in patients with budesonide (0.97 +/- 0.28 mg/kg/min) and without steroids (1.06 +/- 0.32 mg/kg/min), but was similar with control subjects (0.47 +/- 0.20 mg/kg/min). Postprandially, lipid oxidation was lower (p < 0.01) in patients with prednisone (0.32 +/- 0.23 mg/kg/min) than in patients with budesonide (0.75 +/- 0.20 mg/kg/min), without steroids (0.82 +/- 0.23 mg/kg/min), and controls (0.58 +/- 0.15 mg/kg/min). Protein oxidation was significantly higher in patients with prednisone than in the other subjects. CONCLUSIONS In women with CD, prednisone decreases lipid oxidation and increases protein oxidation. These effects are not observed with budesonide and may contribute to the weight gain and side effects commonly observed with prednisone. A low-fat/high-protein diet could be proposed during a course of prednisone.

Abstract
Dietary antigens may act as important stimuli of the mucosal immune system and have led to the study of nutritional therapy for IBD. Patients with active CD respond to bowel rest, along with total enteral nutrition or TPN. Bowel rest and TPN are as effective as corticosteroids at inducing remission for patients with active CD, although benefits are short-lived. Enteral nutrition is consistently less effective than conventional corticosteroids for treatment of active CD. Use of palatable, liquid polymeric diets in active CD is controversial, but these diets are of equal efficacy when compared with elemental diets. UC has not been treated effectively with either elemental diets or TPN. Fish oil contains n-3-PUFA, which inhibits production of proinflammatory cytokines and has some benefit in the treatment of CD. Topical applications of short-chain fatty acids have benefited diversion colitis and distal UC, whereas probiotics hold promise in the treatment of pouchitis.

Abstract
BACKGROUND AND AIMS Obesity is unusual in Crohn's disease and the particularities of the disease in obese patients have not been studied. METHODS 2065 patients were studied retrospectively. Obesity was defined by a BMI value >25.0 at disease onset and >30.0 at any time during the course of the disease. Disease characteristics, therapeutic needs, and year-by-year disease activity were determined in patients with and without obesity. RESULTS 62 patients (3%) were obese. When compared with non-obese patients, obese patients did not show differences regarding sex, intestinal disease location, and disease behavior, but at diagnosis they were older (32 vs 28 years, P = 0.01) and a larger proportion had anoperineal disease (35 vs 24%, P = 0.03). When the 62 obese patients were paired for sex, location of disease at onset, date of birth, and date of diagnosis with 124 non-obese patients, the disease severity assessed by the importance of medical therapy and excisional surgery did not differ in the two groups but time to development of anoperineal abscess or fistula was shorter in obese patients, and obese patients were more prone to develop an active disease (OR 1.50, 95% CI 1.07-2.11) and to require hospitalization (OR 2.35, 95% CI 1.56-3.52) CONCLUSION Obesity in Crohn's disease is associated with more frequent anoperineal complications and a more marked year-by-year disease activity, but does not alter significantly the long-term course of the disease.

Abstract
Nutritional derangements are frequent in inflammatory bowel disease. In the past year significant work has been published examining the mechanisms of impaired food intake in animal models of inflammatory bowel disease, which allow a better understanding of these processes. Data from the same laboratory have shed further light on the relative role of underfeeding and inflammation on the growth retardation associated with intestinal inflammation. Other studies have provided further data on the risk factors and predictive biomarkers of bone loss in patients with inflammatory bowel disease. The potential role of enteral nutrition as primary therapy for Crohn's disease is particularly addressed in this review. Recent contributions to the field emphasized the special importance of this modality of therapy in paediatric patients. The possible mechanisms for such a therapeutic action are not well understood. Other nutrients may have a therapeutic potential in inflammatory bowel disease. In particular, recent data on the in-vivo anti-inflammatory actions of butyrate merit special mention. Finally, novel nutritional therapeutic strategies for inflammatory bowel disease, such as transforming growth factor-beta2-enriched enteral feeding, or hydrothermally processed cereals have recently been explored.

Abstract
Weight loss and malnutrition are common features in patients with Crohn's disease. This study was designed to evaluate diet-induced thermogenesis and substrate oxidation in patients with Crohn's disease. Twenty-three patients (17 women, 6 men; age 34 +/- 2 y) and 17 healthy control subjects (13 women, 4 men; age 36 +/- 3 y) were studied. Resting energy expenditure and fasting substrate oxidation were measured by indirect calorimetry in the morning after an overnight fast. After a standard homogenized test meal (10 kcal/kg), indirect calorimetry was performed every 30 min for 3 h to measure the diet-induced thermogenesis and the postprandial substrate oxidation. In the fasting state, resting energy expenditure was significantly higher in patients than in control subjects (1433 +/- 43 versus 1279 +/- 53 kcal/24 h). Lipid oxidation was higher in patients with Crohn's disease than in control subjects (1.17 +/- 0. 07 versus 0.61 +/- 0.11 mg. kg(-1). min(-1), P < 0.01). Postprandially, diet-induced thermogenesis was significantly lower in patients with Crohn's disease than in control subjects (4.6% +/- 0.5 versus 6.3% +/- 0.5 of energy intake, P < 0.01). Lipid oxidation was significantly higher in patients with Crohn's disease than in control subjects (0.78 +/- 0.05 versus 0.56 +/- 0.08 mg. kg(-1). min(-1), P < 0.05), and glucose oxidation was lower in patients with Crohn's disease than in control subjects. In patients with Crohn's disease, lipid oxidation positively correlates with the disease activity evaluated by the Crohn's Disease Activity Index (r = 0.48, P150), fasting and postprandial lipid oxidation was significantly higher than in patients with inactive Crohn's disease (P < 0.05). In conclusion, patients with Crohn's disease have increased fat oxidation, which correlates with disease activity and this may explain the reduced fat stores in patients with Crohn's disease.
