Aim: To explore patients' follow-up preferences. Background: Optimal follow-up strategies for patients with coeliac disease remain a subject of debate. Research suggests patients' prefer review by dietitians with a doctor available as required. Methods: Patients with coeliac disease under review at our centre, completed a questionnaire assessing their views on what makes follow-up useful based on specific criteria. Bloods tests, symptoms review, dietary assessment, opportunity to ask questions and reassurance. Patients' preferences between follow-up with a hospital doctor, a hospital dietitian, a hospital dietitian with a doctor available, a general practitioner, no follow-up or access when needed were also evaluated. Results: 138 adult patients completed the questionnaire, 80% of patients reported following a strict gluten free diet (mean diagnosis was 7.2 years). Overall, 60% found their follow-up to be 'very useful' valuing their review of blood tests and symptoms (71%) reassurance (60%) and opportunity to ask questions (58%). Follow-up by a dietitian with a doctor available was the most preferred option of review (p<0.001) except when compared to hospital doctor (p=0.75). Novel modalities of follow-up such as telephone and video reviews were regarded as of equal value to face-to-face appointments (65% and 62% respectively). Digital applications were significantly less preferable (38%, p<0.001). Conclusion: Follow-up by a dietitian with a doctor available as needed was the most preferred follow-up method. However, in this study follow-up by a dietitian with doctor available and hospital doctor alone was statistically equivalent. Many patients consider telephone and video follow-up of equal value to face-to-face reviews. [ABSTRACT FROM AUTHOR]

Objective: Coeliac disease (CD) is a lifelong condition requiring strict adherence to a gluten-free (GF) diet and good availability of GF foods is critical to this. Patients with CD from lower socioeconomic groups are recognised to have higher treatment burden and higher food costs may impact this. Therefore, we aimed to assess the availability and cost of GF food in supermarkets and via the internet.Design: Supermarkets and internet shops delivering to homes in a single city (UK) were analysed between February and March 2014. Stores were identified with comprehensive internet searches. Ten commonly purchased items were analysed for cost and compared with standard non-GF alternatives. Direct measurement of the number of GF foods available was compared between stores which were categorised according to previously published work.Setting: Supermarkets covering the whole of Sheffield, UK.Results: None of the budget supermarkets surveyed stocked any GF foods. Quality and regular supermarkets stocked the greatest range, each stocking a median of 22 (IQR 39) items (p<0.0001). All GF foods were at least four times more expensive than non-GF alternatives (p<0.0001). GF products are prevalent online, but 5/10 of the surveyed products were significantly more expensive than equivalents in supermarkets.Conclusions: There is good availability of GF food in regular and quality supermarkets as well as online, but it remains significantly more expensive. Budget supermarkets which tend to be frequented by patients from lower socioeconomic classes stocked no GF foods. This poor availability and added cost is likely to impact on adherence in deprived groups. [ABSTRACT FROM AUTHOR]

Coeliac disease (CD) is a common autoimmune-mediated gluten sensitive enteropathy, with a prevalence of around 1%. While the incidence of CD has increased over the last 2 decades, many cases still remain undiagnosed. The presentation of CD is variable and can be subtle, with it being important to explore both gastrointestinal and extra-intestinal features. The cornerstone of management is adherence to a strict gluten free diet, which requires support and education from an expert gastrointestinal dietitian. Persisting symptoms in individuals requires re-evaluation, with repeat duodenal biopsies sometimes required. Refractory CD affects a small subset of individuals with CD, requiring specialist input., (© Royal College of Physicians 2021. All rights reserved.)

Coeliac disease is a common small intestinal enteropathy which manifests following ingestion of gluten in genetically susceptible individuals. Since gluten was identified as the driving factor in coeliac disease, the gluten-free diet (GFD) has remained the mainstay of treatment. While most individuals will display improvement in symptoms and signs of coeliac disease following institution of the GFD, up to 30% will continue to experience symptoms and/or have persisting intestinal inflammation. These individuals can be classified as having non-responsive coeliac disease (NRCD), which may be associated with dietary indiscretion, slow healing, refractory coeliac disease, and/or an alternative condition. The purpose of this review is to provide an overview of the causes of NRCD in adults, highlight a systematic approach to investigate these patients, and appraise the latest management aspects of this subset of coeliac disease.

Background & Aims: The clinical effects of gluten-sensitive enteropathy with villous atrophy limited to the duodenal bulb (D1) have not been delineated in adults with celiac disease. We investigated the sensitivity of D1 biopsy analysis in the detection of celiac disease, the number and sites of biopsies required to detect ultra-short celiac disease (USCD, villous atrophy limited to D1), and the clinical phenotype of USCD., Methods: We performed a prospective study of 1378 patients (mean age, 50.3 y; 62% female) who underwent endoscopy at a tertiary medical center in the United Kingdom from 2008 through 2014; routine duodenal biopsy specimens were collected from D1 and the second part of the duodenum (D2). Quadrantic D1 biopsy specimens were collected from 171 consecutive patients with a high suspicion of celiac disease (mean age, 46.5 y; 64% female). Clinical data from patients diagnosed with USCD, based on biopsy analysis, were compared with those from patients with conventional celiac disease (CCD) (villous atrophy beyond D1) and individuals without celiac disease (controls). The number of intraepithelial lymphocytes (IELs) and immune phenotypes were compared between D1 vs D2 in patients with celiac disease., Results: Of the 1378 patients assessed, 268 (19.4%) were diagnosed with celiac disease; 9.7% of these patients had villous atrophy confined to D1 (USCD; P < .0001). Collection of a single additional biopsy specimen from any D1 site increased the sensitivity of celiac disease detection by 9.3%-10.8% (P < .0001). Patients with USCD were younger (P = .03), had lower titers of tissue transglutaminase antibody (P = .001), and less frequently presented with diarrhea (P = .001) than patients with CCD. Higher proportions of patients with CCD had ferritin deficiency (P = .007) or folate deficiency (P = .003) than patients with USCD or controls. Patients with celiac disease had a median of 50 IELs/100 enterocytes in D1 and a median of 48 IELs/100 enterocytes (P = .7) in D2. The phenotype of IELs from patients with D1 celiac disease was indistinguishable from those of patients with D2 celiac disease., Conclusions: Collection of a single additional biopsy specimen from any site in the D1 intestine increases the sensitivity of detection for celiac disease. Patients with USCD may have early stage or limited celiac disease, with a mild clinical phenotype and infrequent nutritional deficiencies., (Copyright © 2016 AGA Institute. Published by Elsevier Inc.

Objective: Bile-acid diarrhoea (BAD) is a recognized cause of chronic diarrhoea; however, its detection remains suboptimal. Currently, there is a paucity of follow-up studies evaluating BAD. This work evaluates the natural history of BAD by examining individuals diagnosed with BAD [7 days of Se-homocholic acid taurine (SeHCAT) retention<10%] and determining the use of and response to bile-acid sequestrants (BAS)., Materials and Methods: Of the 515 patients, 40% (207/515) who underwent an SeHCAT test at Sheffield Teaching Hospitals (2001-2012) for chronic diarrhoea had BAD. Of the 207 (51%) patients, 107 were diagnosed between 2001 and 2009. In accordance with the guidelines, all of these patients were commenced on BAS. In March 2013, these individuals were reassessed either in the clinic or over the telephone as part of a local service evaluation project. Comparisons were made of both pretreatment and post-treatment variables using a Wilcoxon rank test., Results: Of the 107 patients, 54% (58/107) were followed up, with a median time since diagnosis of 6 years. Among them, 38% were still using BAS at follow-up, with 28% using alternative antidiarrhoeals. The median stool frequency decreased from seven stools per day to three (P=0.0008) in those using BAS. The 34% of patients not receiving treatment had no change in their daily bowel frequency. The main reason for discontinuing treatment was poor tolerability of the BAS (colestyramine/colestipol)., Conclusion: Our findings indicate that BAD is a chronic condition that best improves with BAS. Consideration should be given to therapeutic options that have a better tolerability profile.

Background and Objectives: In view of the increasing popularity of a gluten-free diet, we sought to determine whether there has been a change in awareness of gluten-related disorders (GRD) among the general public and chefs., Materials and Methods: A face-to-face questionnaire on coeliac disease (CD) and gluten sensitivity (GS) was performed on the general public and chefs based in Sheffield, UK. The assessment was first carried out in 2003 and repeated in 2013., Results: In total, 513 public members in 2003 (mean age 49.2 years, 62% women) were compared with 575 public members in 2013 (mean age 37.8 years, 57% women). There was a significant increase in the public's awareness of GRD from the years 2003 to 2013, CD [44.2% to 74.4%, adjusted odds ratio (AOR) 3.9; 95% confidence interval (CI) 3.0-5.19] and GS (58.3% to 89%, AOR 7.1; 95% CI 5.0-9.98; P<0.001). Also, 322 chefs in 2003 (mean age 37.6 years, 15% women) were compared with 265 chefs in 2013 (mean age 27.1 years, 38% women). There was a significant increase in chefs' awareness of GRD from the years 2003 to 2013, CD (17.1% to 78.1%, AOR 12.5; 95% CI 7.9-19.6) and GS (9.3% to 87.5%, AOR 65.7; 95% CI 35.4-122; P<0.001). Whereas in 2003 the public were significantly more aware of GRD than chefs, by 2013, this had reached a similar prevalence in both groups. In addition, the correct recognition of the gluten-free symbol was 44% for the public and 40% for chefs (P=0.28). Gluten-free products were sold by 41% of restaurants and 27% of takeaways (P=0.07)., Conclusion: There has been a marked increase in both the public's and chefs' awareness of GRD. Such findings may ease the social phobia that individuals with GRD have traditionally been accustomed to.

Background: There has been increasing interest in subclassifying irritable bowel syndrome (IBS) to make a positive diagnosis., Aim: The aim of this study was to assess the population prevalence of differing subtypes, investigational pathways and diagnostic outcomes., Materials and Methods: Data were prospectively collected from three groups between 2005 and 2012. Group 1 [n=1002, 55% female, mean age 39 years (range 16-93 years)] comprised healthy volunteers who were interviewed using the Rome III diagnostic questionnaire. In secondary care, group 2 [n=64, 80% female, mean age 44 years (range 23-79 years)] comprised patients with constipation-predominant IBS (IBS-C) and group 3 [n=333, 66% female, mean age 51 years (range 23-92 years)] comprised patients with diarrhoea-predominant IBS (IBS-D). In groups 2 and 3, demographic data and diagnostic yield of investigations were evaluated as per normal clinical practice., Results: IBS prevalence in group 1 was 6% (60/1002). IBS-C patients were significantly older than those with IBS-D (mean age 45 vs. 30 years, P=0.027). In groups 2 and 3, patients with IBS-C underwent a total of 56 additional investigations (mean 0.88 per patient), which was significantly lower than the number of investigations undertaken in the IBS-D group of 734 (mean 2.2 per patient, P<0.001). Further investigations in group 3 (IBS-D) identified an alternative diagnosis in 22%, whereas in group 2 (IBS-C) this was 0% (P<0.0001)., Conclusion: This is the first study to evaluate the population prevalence of different IBS subtypes within a UK population. Although further investigations in IBS-D patients have led to alternative diagnoses, none were identified in the IBS-C population. The merits of investigating IBS-C patients should be questioned.

Background & Aim: There is a paucity of data reflecting the symptomatic responses to dietary gluten (SRDG) in patients with Coeliac Disease (CD). We aimed to determine the type, timing and severity of SRDG with reference to a range of disease-related factors., Methods: Postal survey of 224 biopsy-proven patients including gluten-free diet (GFD) adherence, symptom checklist, ROME II criteria and The Hospital Anxiety & Depression Scale. Case-note review was also conducted., Results: 26% of respondents were male. Full GFD adherence: n=159 (70%). Irritable bowel syndrome (IBS): n=50 (22%). Anxiety: n=30 (13%); Depression: n=33 (14%); Anxiety & Depression: n=72 (32%). Pruritus, fatigue and bloating were a more common SRDG in the partial/none GFD adherent group (p=ns). Co-existing IBS was associated with a greater prevalence of nausea and fatigue in response to gluten (p=<0.05). Fully GFD adherent patients are more likely to have SRDG <1hr than partial/none adherent (OR 4.8; p=0.004), as are a third of patients with co-existing IBS (OR 1.5; p=0.027) and those patients at risk of both anxiety and depression (OR 1.9; p=0.04). Inadvertent exposure to dietary gluten in the fully GFD adherent group is more likely to result in a severe SRDG in comparison to symptoms arising prior to consistent GFD adherence (OR 2.3; p=0.01). IBS sufferers are also more likely to rate their SRDG as severe in nature (OR 1.4; p=0.038)., Conclusion: Patients with consistent GFD adherence experience a SRDG faster and more severe in comparison to prior gluten exposure possibly demonstrating an adept immunological response. Anxiety and depression also enhance the speed of symptom onset and co-existing visceral hypersensitivity is a risk factor for severe reactions to dietary gluten.

Background & Aims: Capsule endoscopy has been shown to be useful in diagnosing small bowel Crohn's disease. Faecal lactoferrin has been shown to have a high sensitivity and specificity in discriminating between inflammatory bowel disease and irritable bowel syndrome. There have been no studies on the use of faecal lactoferrin in the setting of suspected Crohn's disease using capsule endoscopy. Our aim was to investigate the clinical utility of lactoferrin in patients with suspected Crohn's disease using capsule endoscopy., Methods: Data was collected prospectively on patient symptoms, family history and blood parameters. Patients were requested to return a stool sample and quantitative analysis using sandwich ELISA was performed for faecal lactoferrin., Results: Seventeen patients were recruited with all patients having had more than one criterion for referral. The diagnostic yield for capsule endoscopy was 41%, of which 71% of patients had an elevated faecal lactoferrin (correlation coefficient 0.56, p=0.01). The sensitivity, specificity, positive predictive value and negative predictive value of faecal lactoferrin were 71%, 100%, 100% and 83%, respectively., Conclusion: Faecal lactoferrin has a high positive and negative predictive value for the diagnosis of small bowel Crohn's disease, detected by capsule endoscopy. Faecal lactoferrin is a useful marker (in conjunction with clinical parameters) to determine which patients should be referred for capsule endoscopy.

Objective: The relationship between coeliac disease and inflammatory bowel disease (IBD) is controversial. The aim of this study was to determine the prevalence of coeliac disease in IBD and the prevalence of IBD in coeliac disease., Material and Methods: Patients were enrolled from specialist IBD and coeliac clinics. Antigliadins, endomysial, tissue transglutaminase antibody and total IgA levels were measured in IBD patients. Patients with positive antibodies were offered a duodenal biopsy. The notes on coeliac patients were reviewed for colonoscopic and biopsy findings. Controls were recruited from the local population., Results: The study included 305 patients with coeliac disease, 354 with IBD and 601 healthy controls. The IBD group comprised 154 ulcerative colitis (UC) cases, 173 Crohn's disease, 18 indeterminate colitis and 9 cases of microscopic colitis. Forty-seven patients had positive antibodies and 3 had villous atrophy on biopsy. All three patients had positive anti-tissue transglutaminase antibodies but only two were endomysial antibody (EMA) positive. Ten coeliac patients had IBD (5 UC and 5 lymphocytic colitis). Five controls had coeliac disease and 2 had IBD (1 Crohn's disease and 1 UC). Stepwise multiple logistic regression showed only antibody positivity as being significant (p<0.0001)., Conclusions: The prevalence of IBD in coeliac disease was increased 10-fold compared with that in controls (odds ratio 9.98, 95% CI 2.8-45.9, p=0.0006), while the prevalence of coeliac disease in IBD was comparable with that in controls (odds ratio 1.02, 95% CI, 0.24-4.29, p=1.0).

Objectives: To establish the prevalence of coeliac disease in the general population and in specific conditions, such as irritable bowel syndrome, iron deficiency anaemia, fatigue and other coeliac-related conditions., Methods: Primary-care-based cross-sectional study using immunoglobulins, IgA/IgG antigliadin antibodies and endomysial antibodies to initially recognize coeliac disease. A total of 1200 volunteers were recruited from January 1999 to June 2001 from five general practices in South Yorkshire, UK. Any participant with a positive IgA antigliadin antibody, positive endomysial antibody, or only IgG antigliadin antibody in the presence of IgA deficiency was offered a small-bowel biopsy to confirm the diagnosis of coeliac disease., Results: Twelve new cases of coeliac disease were diagnosed from 1200 samples. The prevalence of coeliac disease in this primary care population sample is 1% (95% CI 0.4-1.3%). The prevalence of coeliac disease was 3.3% (4/123) in participants with irritable bowel syndrome, 4.7% (3/64) in participants with iron deficiency anaemia, and 3.3% (3/92) in participants with fatigue., Conclusions: This study describes the prevalence of undiagnosed adult coeliac disease in primary care patients with irritable bowel syndrome, iron deficiency anaemia and fatigue. Underdiagnosis of coeliac disease is common in primary care. A case-finding approach would avoid delays in diagnosis and the associated morbidity or potential complications of coeliac disease. A low threshold for serological screening of patients with coeliac-associated symptoms or conditions would be an optimal strategy.
