RESUMEN

INTRODUCTION: Extensive research has provided an important understanding of the impact of inflammatory bowel disease (IBD) on nutrient intake, requirements and metabolism. By contrast, there has been limited research examining the psychosocial aspects of food, eating and drinking in IBD. The present study aimed to address this unmet need. METHODS: Qualitative semi-structured interviews regarding the perceptions and psychosocial impact of food, eating and drinking were undertaken with 28 purposively selected people with IBD. Interviews were audio-recorded and transcribed verbatim. Colaizzi's framework was used to structure the data analysis. RESULTS: Five major themes were identified. IBD symptoms and both surgical and medical treatments were described as having a direct impact on eating and drinking, with participants also using different food-related strategies to control IBD symptoms. These included a process of experimentation to identify trigger foods, following a severely restricted and limited diet, eating small portions, and eating more frequently. However, their limited knowledge about if, and how, food affected their symptoms, often resulted in negative coping strategies that impacted on psychosocial functioning, including a lack of enjoyment of eating, being afraid to eat and finding social occasions stressful. Managing food and drinking also made food shopping and preparation more burdensome, creating problems with families, at work and for social life, as well as the need for careful preparation and advanced planning of activities. CONCLUSIONS: Inflammatory bowel disease has a profound impact on psychosocial aspects of food and nutrition, which impacts on 'food-related quality of life' (FRQoL). Further research is required to identify interventions that will improve FRQoL in patients with IBD.

RESUMEN

Dietary restriction of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) is effective in the management of functional gastrointestinal symptoms that occur in irritable bowel syndrome (IBS). Numerous reviews have been published regarding the evidence for their restriction in the low FODMAP diet; however, few reviews discuss the implementation of the low FODMAP diet in practice. The aim of this review is to provide practical guidance on patient assessment and the implementation and monitoring of the low FODMAP diet. Broadly speaking, the low FODMAP diet consists of three stages: FODMAP restriction; FODMAP reintroduction; and FODMAP personalisation. These stages can be covered in at least two dietetic appointments. The first appointment focuses on confirmation of diagnosis, comprehensive symptom and dietary assessment, detailed description of FODMAPs and their association with symptom induction, followed by counselling regarding FODMAP restriction. Dietary counselling should be tailored to individual needs and appropriate resources provided. At the second appointment, symptoms and diet are re-assessed and, if restriction has successfully reduced IBS symptoms, education is provided on FODMAP reintroduction to identify foods triggering symptoms. Following this, the patient can follow FODMAP personalisation for which a less restrictive diet is consumed that excludes their personal FODMAP triggers and enables a more diverse dietary intake. This review provides evidence and practice guidance to assist in delivering high-quality clinical service in relation to the low FODMAP diet.

RESUMEN

BACKGROUND: Probiotics are often taken by individuals with irritable bowel syndrome (IBS). Which products are effective is unclear, despite an increasing research base. This project will systematically review which strain- and dose- specific probiotics can be recommended to adults with IBS to improve symptoms and quality of life (QoL). It is part of a broader systematic review to update British Dietetic Association guidelines for the dietary management of IBS in adults. METHODS: CINAHL, Cochrane, Embase, Medline, Scopus and Web of Science were searched for systematic reviews (SRs) of randomised controlled trial (RCT)s recruiting adults with IBS comparing probiotic intervention with placebo. AMSTAR, risk of bias and diet bias tools were used to appraise methodological quality. Symptom and QoL data were appraised to develop probiotic-specific evidence statements on clinically meaningful and marginal outcomes in various settings, graded clinical practice recommendations and practical considerations. RESULTS: Nine systematic reviews and 35 RCTs were included (3406 participants) using 29 dose-specific probiotic formulations. None of the RCTs were at low risk of bias. Twelve out of 29 probiotics (41%) showed no symptom or QoL benefits. Evidence indicated that no strain or dose specific probiotic was consistently effective to improve any IBS symptoms or QoL. Two general clinical practice recommendations were made. CONCLUSIONS: Symptom outcomes for dose-specific probiotics were heterogeneous. Specific probiotic recommendations for IBS management in adults were not possible at this time. More data from high-quality RCTs treating specific symptom profiles are needed to support probiotic therapy in the management of IBS.

RESUMEN

BACKGROUND: The first British Dietetic Association (BDA) guidelines for the dietary management of irritable bowel syndrome (IBS) in adults were published in 2012. Subsequently, there has been a wealth of new research. The aim of this work was to systematically review the evidence for the role of diet in the management of IBS and to update the guidelines. METHODS: Twelve questions relating to diet and IBS were defined based on review of the previous guideline questions, current evidence and clinical practice. Chosen topics were on healthy eating and lifestyle (alcohol, caffeine, spicy food, elimination diets, fat and fluid intakes and dietary habits), milk and dairy, dietary fibre, fermentable carbohydrates, gluten, probiotics and elimination diets/food hypersensitivity. Data sources were CINAHL, Cochrane Register of Controlled Trials, Embase, Medline, Scopus and Web of Science up to October 2015. Studies were assessed independently in duplicate using risk of bias tools specific to each included study based on inclusion and exclusion criteria for each question. National Health and Medical Research Council grading evidence levels were used to develop evidence statements and recommendations, in accordance with Practice-based Evidence in Nutrition Global protocol used by the BDA. RESULTS: Eighty-six studies were critically appraised to generate 46 evidence statements, 15 clinical recommendations and four research recommendations. The IBS dietary algorithm was simplified to first-line (healthy eating, provided by any healthcare professional) and second-line [low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) to be provided by dietitian] dietary advice. CONCLUSIONS: These guidelines provide updated comprehensive evidence-based details to achieve the successful dietary management of IBS in adults.

RESUMEN

BACKGROUND: Restriction of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) is an effective dietary treatment for irritable bowel syndrome (IBS). Patient dietary education is essential but labour intensive. Group FODMAP education may alleviate this somewhat but has not previously been investigated. The present study aimed to investigate the clinical effectiveness of low FODMAP group education in patients with IBS and to explore the cost of a group pathway. METHODS: Patients with IBS (n = 364) were assessed for their suitability to attend dietitian-led group education or traditional one-to-one education in a novel group pathway. Clinical effectiveness (global symptom question, symptom prevalence, stool output) were compared at baseline and follow-up using the chi-squared test. The costs of the novel group pathway were assessed using a decision model. RESULTS: The global symptom question indicated more patients were satisfied with their symptoms following dietary advice, in both group education [baseline 48/263 (18%) versus follow-up 142/263 (54%), P < 0.001] and one-to-one education [baseline 5/101 (5%) versus follow-up 61/101 (60%), P < 0.001], with no difference between group and one-to-one education at follow-up (P = 0.271). Overall, there was a significant decrease in symptom severity from baseline to follow-up (P < 0.001 for both groups) but no difference in symptom response between group and one-to-one education. The cost for the group education pathway for all 364 patients was £31 713.36. CONCLUSIONS: The present study shows that dietitian-led FODMAP group education is clinically effective and the costs associated with a FODMAP group pathway are worthy of further consideration for routine clinical care.

RESUMEN

BACKGROUND: Food intolerance is non-immunological and is often associated with gastrointestinal symptoms. AIM: To focus on food intolerance associated with gastrointestinal symptoms and critically appraise the literature in relation to aetiology, diagnosis, mechanisms and clinical evidence. METHODS: A search using the terms and variants of food intolerance, lactose, FODMAP, gluten, food chemicals within Pubmed, Embase and Scopus was carried out and restricted to human studies published in English. Additionally, references from relevant papers were hand searched for other appropriate studies. RESULTS: Food intolerance affects 15-20% of the population and may be due to pharmacological effects of food components, noncoeliac gluten sensitivity or enzyme and transport defects. There have been significant advances in understanding the scientific basis of gastrointestinal food intolerance due to short-chain fermentable carbohydrates (FODMAPs). The most helpful diagnostic test for food intolerance is food exclusion to achieve symptom improvement followed by gradual food reintroduction. A low FODMAP diet is effective, however, it affects the gastrointestinal microbiota and FODMAP reintroduction to tolerance is part of the management strategy. CONCLUSIONS: There is increasing evidence for using a low FODMAP diet in the management of functional gastrointestinal symptoms where food intolerance is suspected. Exclusion diets should be used for as short a time as possible to induce symptom improvement, and should be followed by gradual food reintroduction to establish individual tolerance. This will increase dietary variety, ensure nutritional adequacy and minimise impact on the gastrointestinal microbiota.

RESUMEN

BACKGROUND: Nutritional assessment and dietary intervention, particularly enteral nutrition, are important in the management of Crohn's disease (CD). National audits have reported that dietetic resourcing in gastroenterology is inadequate. The present study aimed to identify current practice in the nutritional assessment and dietary management of enteral nutrition in CD, as well as investigate the factors that influenced it. METHODS: A nationwide questionnaire survey adopting complete population sampling of all 296 U.K. acute hospitals was undertaken aiming to determine dietetic resourcing for gastroenterology. In addition, the case-note review method was used to investigate approaches to nutritional assessment and dietary management of enteral nutrition as treatment for active CD. RESULTS: Data were returned from 149 (56%) hospitals, providing assessment and management information on 190 patients. The median number of dietetic sessions dedicated to gastroenterology was 2 per week (interquartile range 4). Hospitals with five or more sessions per week dedicated to gastroenterology used a greater number of components in their nutritional assessment [mean (SD) 21.5 ( 5.0)] than those with fewer sessions [mean (SD) 19.6 (SD) 6.1, P = 0.05]. Enteral nutrition was perceived to be effective in 100 (55%) of 182 patients. The major reasons for limited success were poor compliance and inadequate volumes consumed, as well as insufficient treatment duration. CONCLUSIONS: The components included in a nutritional assessment of CD patients are significantly lower in hospitals with fewer dietetic gastroenterology sessions. Focus on improving compliance and duration of enteral nutrition is urgently required to maximise the success of enteral nutrition in the treatment of CD.

RESUMEN

BACKGROUND: Crohn's disease is a debilitating chronic inflammatory bowel disease. Appropriate use of diet and nutritional therapy is integral to the overall management strategy of Crohn's disease. The aim was to develop evidence-based guidelines on the dietary management of Crohn's disease in adults. METHODS: Questions relating to the dietary management of Crohn's disease were developed. These included the roles of enteral nutrition to induce remission, food re-introduction diets to structure food re-introduction and maintain remission, and dietary management of stricturing disease, as well as whether probiotics or prebiotics induce or maintain remission. A comprehensive literature search was conducted and relevant studies from January 1985 to November 2009 were identified using the electronic database search engines CINAHL, Cochrane Library, EMBASE, MEDLINE, Scopus and Web of Science. Evidence statements, recommendations, practical considerations and research recommendations were developed. RESULTS: Fifteen research papers were critically appraised and the evidence formed the basis of these guidelines. Although corticosteroids appear to be more effective, enteral nutrition (elemental or non-elemental) can be offered as an alternative option to induce disease remission. After a course of enteral nutrition, food re-introduction diets may be useful to structure food re-introduction and help maintain disease remission. Dietary fibre is contraindicated in the presence of strictures as a result of the risk of mechanical obstruction. The use of probiotics and prebiotics is not currently supported. CONCLUSIONS: As an alternative to corticosteroids, evidence supports enteral nutrition to induce disease remission. Food re-introduction diets provide structure to food re-introduction and help maintain disease remission. These guidelines aim to reduce variation in clinical practice.

RESUMEN

BACKGROUND: Orofacial granulomatosis (OFG) is a rare disease of unknown cause. A cinnamon- and benzoate-free diet is successful in up to 72% of patients. Phenolic acids are among the chemical constituents restricted in this diet, which avoids some but not all of these structurally similar compounds. The present study aimed to: (i) develop a novel diet low in phenolic acids; (ii) implement this in a small clinical trial; and (iii) assess its nutritional adequacy. METHODS: A literature review identified 10 papers quantifying phenolic acids from which 91 10-mg phenolic acid exchanges were devised. A phenolic acid exclusion diet with precautionary micronutrient supplementation was designed and implemented in 10 patients. Phenolic acids were excluded for 6 weeks and were reintroduced at a rate of one exchange every second day for 6 weeks. Wilcoxon matched pairs tests analysed disease outcomes measured by an oral disease severity scoring tool at weeks 0, 6 and 12. Nutritional adequacy was assessed, excluding micronutrient supplementation, at weeks 0 and 6, and compared intakes with dietary reference values. RESULTS: The diet was nutritionally inadequate for a range of micronutrients. Seven of 10 patients responded. Mean [standard deviation (SD)] severity scores improved from week 0-6 [20.8 (9.39) and 10.1 (5.72); P = 0.009] and were maintained in five patients who completed the reintroduction [6.6 (3.13) and 7.2 (5.54); P = 0.713]. CONCLUSIONS: A low phenolic acid diet with micronutrient supplementation holds promise of a novel dietary treatment for OFG. Further work is required in larger studies to determine long-term outcomes.

RESUMEN

BACKGROUND: Orofacial granulomatosis (OFG) is a chronic granulomatous condition of the mouth, face and lips. Recent work demonstrates a high rate of atopy and silver birch sensitisation from skin prick testing (SPT). Oral allergy syndrome (OAS) is an acute oro-pharyngeal IgE mediated reaction, triggered by foods that cross react with pollens, most commonly silver birch. The aim of this study was to determine if patients with OFG and positive SPT to common OAS associated pollens responded to avoidance of cross reactive foods. METHODS: Patients with OFG and positive SPT to silver birch, grass, mugwort, ragweed and latex were required to avoid cross reacting foods, for 6 weeks and, in those who responded, for a total of 12 weeks. All had standardized oral examinations and were given severity scores (SS) at each appointment. RESULTS: Twenty two of 47 (47%) patients had one or more positive SPT and 13/22 completed 6 weeks on the diet. No difference was seen in SS between weeks 0 (14.62 ± 11.16) and 6 (13.31 ± 10.33; P = 0.656). Six of 14 (43%) had significantly improved SS (week 0; 19.17 ± 12.95, week 6; 10.83 ± 4.99, P = 0.027). Five completed 12 weeks and no further improvement was seen (week 6; 11 ± 5.57, week 12; 10.4 ± 9.94; P = 0.068). Two patients required no further treatments. CONCLUSIONS: On an intention to treat basis, only 2/14 patients improved and required no further intervention. Whilst this diet cannot be recommended routinely, the improvement seen in some patients raises questions about the role of OAS in patients with OFG.

RESUMEN

BACKGROUND: Manipulation of dietary fibre intake represents a longstanding treatment for patients with irritable bowel syndrome (IBS), particularly for those with constipation. Linseeds are often recommended by both clinicians and dietitians as a source of dietary fibre to alleviate symptoms. Recent guidance on the management of irritable bowel syndrome (IBS) advises that linseeds may reduce wind and bloating, although there is limited clinical evidence to support this recommendation. The present pilot study aimed to compare the clinical effectiveness of: (i) whole linseeds versus ground linseeds; (ii) whole linseeds versus no linseeds; and (iii) ground linseeds versus no linseeds in the management of IBS symptoms. METHODS: In an open randomised controlled trial, subjects with IBS (n = 40) were allocated to one of three intervention groups: two tablespoons of whole linseeds per day (n = 14), two tablespoons of ground linseeds per day (n = 13) and no linseeds as controls (n = 13). Symptom severity (primary outcome) and bowel habit were assessed before and after a 4-week intervention and statistical differences between the groups were compared. RESULTS: Thirty-one subjects completed the present study. Between-group analysis comparing the improvement in symptom severity did not reach statistical significance for whole linseeds (n = 11) versus ground linseeds (n = 11; P = 0.62), whole linseeds versus controls (n = 9; P = 0.12) and ground linseeds versus controls (P = 0.10). There were no significant changes in stool frequency or stool consistency for any of the groups. CONCLUSIONS: Linseeds may be useful in relief of IBS symptoms. Further research is needed to detect clear differences between the effects of whole and ground linseeds.

RESUMEN

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic debilitating functional gastrointestinal disorder. Diet and lifestyle changes are important management strategies. The aim of these guidelines is to systematically review key aspects of the dietary management of IBS, with the aim of providing evidence-based guidelines for use by registered dietitians. METHODS: Questions relating to diet and IBS symptom management were developed by a guideline development group. These included the role of milk and lactose, nonstarch polysaccharides (NSP), fermentable carbohydrates in abdominal bloating, probiotics and empirical or elimination diets. A comprehensive literature search was conducted and relevant studies from January 1985 to November 2009 were identified using the electronic database search engines: Cinahl, Cochrane Library, Embase, Medline, Scopus and Web of Science. Evidence statements, recommendations, good practice points and research recommendations were developed. RESULTS: Thirty studies were critically appraised. A dietetic care pathway was produced following a logical sequence of treatment and formed the basis of these guidelines. Three lines of dietary management were identified. first line: Clinical and dietary assessment, healthy eating and lifestyle management with some general advice on lactose and NSP. Second line: Advanced dietary interventions to improve symptoms based on NSP, fermentable carbohydrates and probiotics. Third line: Elimination and empirical diets. Research recommendations were also identified relating to the need for adequately powered and well designed randomised controlled trials. CONCLUSIONS: These guidelines provide evidence-based details of how to achieve the successful dietary management of IBS.

RESUMEN

BACKGROUND: Patients with systemic lupus erythematosus (SLE) may require prolonged periods of corticosteroid therapy which lead to excessive weight gain and increased cardiovascular risk. OBJECTIVE: To assess the utility of a low glycaemic index diet in patients with corticosteroid dependent SLE in achieving weight loss and improving glycaemic control. DESIGN: A total of 23 women were enrolled in a 6 week study. All had mild, stable SLE, were receiving corticosteroids and had a body mass index > 25 kg/m(2). Subjects were randomly assigned to a low glycaemic index (Low GI) diet or a calorie restricted (Low Cal) diet. The primary end point was weight loss. Secondary end points included tolerability of diet, bio-markers of cardiovascular risk, disease activity, fatigue and sleep quality. RESULTS: Weight loss in both treatment groups was significant (mean ± SD: Low GI diet 3.9 ± 0.9 kg; Low Cal diet 2.4 ± 2.2 kg, p < 0.01 from baseline in each group). There were also significant improvements in waist and hip measurements. However, the difference in weight loss and waist and hip measurements between the two diet groups was not statistically significant. There was a statistically significant reduction in Fatigue Severity Scale in both diet groups, (p < 0.03). Both Low GI and Low Cal diets were well tolerated, resulting in no serious adverse effects or increase in disease activity. CONCLUSION: Significant weight loss is achievable over 6 weeks in a diet-specific trial in subjects with stable SLE, who are on low dose prednisolone. Both diets were equally tolerable, and did not cause flares in disease activity. Our results suggest that dietary manipulation may significantly improve fatigue in subjects with SLE.

RESUMEN

BACKGROUND: Orofacial granulomatosis is a rare chronic granulomatous inflammatory disease of the lips, face and mouth. The aetiology remains unclear but may involve an allergic component. Improvements have been reported with cinnamon- and benzoate-free diets. AIMS: To explore the prevalence of compound and food sensitivity and examine the dietary treatments used in orofacial granulomatosis. METHODS: A comprehensive literature search was carried out and relevant studies from January 1933 to January 2010 were identified using the electronic database search engines; AGRIS 1991-2008, AMED 1985-2008, British Nursing and Index archive 1985-2008, EMBASE 1980-2008, evidence based medicine review databases (e.g. Cochrane DSR), International Pharmaceutical and Medline 1950-2008. RESULTS: Common sensitivities identified, predominantly through patch testing, were to benzoic acid (36%) food additives (33%), perfumes and flavourings (28%), cinnamaldehyde (27%), cinnamon (17%), benzoates (17%) and chocolate (11%). The cinnamon- and benzoate-free diet has been shown to provide benefit in 54-78% of patients with 23% requiring no adjunctive therapies. A negative or positive patch test result to cinnamaldehyde, and benzoates did not predict dietary outcome. The most concentrated source of benzoate exposure is from food preservatives. Use of liquid enteral formulas can offer a further dietary therapy, particularly in children with orofacial granulomatosis. CONCLUSION: Management of orofacial granulomatosis is challenging but cinnamon- and benzoate-free diets appear to have a definite role to play.

RESUMEN

BACKGROUND: Emerging evidence indicates that the consumption of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) may result in symptoms in some patients with irritable bowel syndrome (IBS). The present study aimed to determine whether a low FODMAP diet is effective for symptom control in patients with IBS and to compare its effects with those of standard dietary advice based on the UK National Institute for Health and Clinical Excellence (NICE) guidelines. METHODS: Consecutive patients with IBS who attended a follow-up dietetic outpatient visit for dietary management of their symptoms were included. Questionnaires were completed for patients who received standard (n = 39) or low FODMAP dietary advice (n = 43). Data were recorded on symptom change and comparisons were made between groups. RESULTS: In total, more patients in the low FODMAP group reported satisfaction with their symptom response (76%) compared to the standard group (54%, P = 0.038). Composite symptom score data showed better overall symptom response in the low FODMAP group (86%) compared to the standard group (49%, P < 0.001). Significantly more patients in the low FODMAP group compared to the standard group reported improvements in bloating (low FODMAP 82% versus standard 49%, P = 0.002), abdominal pain (low FODMAP 85% versus standard 61%, P = 0.023) and flatulence (low FODMAP 87% versus standard 50%, P = 0.001). CONCLUSIONS: A low FODMAP diet appears to be more effective than standard dietary advice for symptom control in IBS.

RESUMEN

BACKGROUND: Approximately 70% of the world population has hypolactasia, which often remains undiagnosed and has the potential to cause some morbidity. However, not everyone has lactose intolerance, as several nutritional and genetic factors influence tolerance. AIMS: To review current clinical practice and identify published literature on the management of lactose intolerance. METHODS: PubMed was searched using the terms lactose, lactase and diet to find original research and reviews. Relevant articles and clinical experience provided the basis for this review. RESULTS: Lactose is found only in mammalian milk and is hydrolysed by lactase in the small intestine. The lactase gene has recently been identified. 'Wild-type' is characterized by lactase nonpersistence, often leading to lactose intolerance. Two genetic polymorphisms responsible for persistence have been identified, with their distribution concentrated in north Europeans. Symptoms of lactose intolerance include abdominal pain, bloating, flatulence and diarrhoea. Diagnosis is most commonly by the lactose hydrogen breath test. However, most people with hypolactasia, if given appropriate advice, can tolerate some lactose-containing foods without symptoms. CONCLUSION: In clinical practice, some people with lactose intolerance can consume milk and dairy foods without developing symptoms, whereas others will need lactose restriction.

RESUMEN

Iron deficiency anaemia is one of the most common disorders in the world. Also, one third of inflammatory bowel disease (IBD) patients suffer from recurrent anaemia. Anaemia has significant impact on the quality of life of affected patients. Chronic fatigue, a frequent IBD symptom itself, is commonly caused by anaemia and may debilitate patients as much as abdominal pain or diarrhoea. Common therapeutic targets are the mechanisms behind anaemia of chronic disease and iron deficiency. It is our experience that virtually all patients with IBD associated anaemia can be successfully treated with a combination of iron sucrose and erythropoietin, which then may positively affect the misled immune response in IBD.
