Long-term follow-up in patients with coeliac disease in the pandemic-era: a view from Sheffield the NHS England national centre for adult coeliac disease.

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.

Does a Gluten-Free Diet Improve Quality of Life and Sleep in Patients with Non-Coeliac Gluten/Wheat Sensitivity?

INTRODUCTION: The role of a gluten-free diet (GFD) in Non-Coeliac Gluten/Wheat Sensitivity (NCGWS) is unclear. We present the largest study comparing adherence to a GFD in patients with Coeliac Disease (CD) and NCGWS and assess its impact on quality of life (QoL) and sleep in patients with NCGWS. METHODS: Patients with NCGWS at a tertiary centre completed the Coeliac Disease Adherence Test (CDAT), Coeliac Symptom Index (CSI) and Sleep Condition Indicator (SCI). Higher CDAT scores indicate worse adherence, higher CSI scores indicate poorer QoL, and higher SCI scores indicate better sleep. CDAT scores were correlated with CSI and SCI scores. A second group of patients with CD completed the CDAT questionnaire only. Results were compared with the CDAT responses from the NCGWS group. RESULTS: For the NCGWS cohort (n = 125), the median CDAT score was 17/35, indicating poor adherence. The median CSI score was 44/80, with 40% of scores associated with a poor QoL. The median SCI score was 14/32, and DSM-V criteria for insomnia was met by 42% of patients. There was a positive correlation between CSI and CDAT scores (r = 0.59, p < 0.0001) and a negative correlation between SCI and CDAT scores (r = -0.37, p = 0.0002). In the CD cohort (n = 170), the median CDAT score was 13/35. Patients with NCGWS had poorer adherence compared to CD (CDAT: 17.0 vs. 13.0, respectively, p = 0.0001). CONCLUSION: Patients with NCGWS adhere to a GFD less than those with CD. Poorer adherence to a GFD in patients with NCGWS correlates with a worse QoL and sleep performance.

Current evidence for dietary therapies in irritable bowel syndrome.

PURPOSE OF REVIEW: Diet appears to trigger symptoms in the majority of individuals with irritable bowel syndrome (IBS) and is associated with a reduced quality of life. There has been a recent focus on the role of dietary therapies to manage individuals with IBS. The aim of this review is to discuss the utility of traditional dietary advice (TDA), low-FODMAP diet (LFD) and gluten-free diet (GFD) in IBS. RECENT FINDINGS: Several recent randomized controlled trials (RCTs) have been published demonstrating the efficacy of the LFD and GFD in IBS, with the evidence base for TDA being predominantly based on clinical experience, with emerging RCTs evaluating TDA. Only one RCT has been published to date comparing TDA, LFD and GFD head to head, with no difference noted between diets in terms of efficacy. However, TDA has been noted to be more patient-friendly and is commonly implemented as a first-line dietary therapy. SUMMARY: Dietary therapies have been demonstrated to improve symptoms in patients with IBS. In view of insufficient evidence to recommend one diet over another currently, specialist dietetic input in conjunction with patient preference is required to determine implementation of dietary therapies. Novel methods of dietetic delivery are required in view of the lack of dietetic provision to deliver these therapies.

DQA1*0102 DQB1*0602 haplotype distinguishes coeliac disease and its complications from gluten unrelated enteropathies.

BACKGROUND: Duodenal villous atrophy is due not only to coeliac disease and its complications but also to other rare enteropathies unrelated to gluten consumption, defined as noncoeliac enteropathies. The diagnosis of noncoeliac enteropathies remains challenging, and HLA typing has been widely used to exclude coeliac disease if DQ2 and DQ8 alleles are absent. However, the frequency of the various HLA alleles in noncoeliac enteropathies is still unknown. AIMS: To describe the HLA genetic profile of patients affected by noncoeliac enteropathies who have been evaluated at our centres between 2000 and 2021, and to investigate the diagnostic role of HLA typing. METHODS: Genomic DNA was collected from 44 Italian and 19 British adult patients with noncoeliac enteropathies. Patient genotypes were compared with those of healthy Italian and British populations obtained from HLA bone marrow donors' banks. In addition, genotypes were also compared with those of patients with coeliac disease and complicated coeliac disease. RESULTS: Both in the Italian and in the British group, the DQA1*0102 DQB1*0602 haplotype and related alleles occurred significantly more frequently in patients with noncoeliac enteropathies compared to coeliac disease and complicated coeliac disease. CONCLUSIONS: Together with negative HLA-DQ2 and DQ8 haplotypes, the DQA1*0102 DQB1*0602 haplotype can be used to guide the differential diagnosis between coeliac disease and noncoeliac enteropathies.

What are the clinical consequences of 'potential' coeliac disease?

BACKGROUND: There is limited data on the clinical consequences of potential coeliac disease (PCD). AIM: To compare the presentation of PCD with coeliac disease (CD). METHODS: A retrospective study of adult PCD patients (>18 years) was performed. Presenting manifestations, serology and HLA-DQ genotyping were compared to an age-at-diagnosis and sex-matched CD cohort. RESULTS: The PCD cohort comprised 84 patients (median age 37 years, 63% female). The majority of PCD patients were symptomatic at presentation (PCD 91.7% versus CD cohort 94.0%, p = 0.55). In total, 79.8% and 76.2% of the PCD and CD cohorts respectively reported ≥1 gastrointestinal symptoms at presentation (p = 0.58). Extraintestinal presentation was less common in PCD than CD (65.5% versus 79.8% respectively, p = 0.038). PCD patients had fewer haematinic deficiencies than those with CD (iron 21.4% versus 41.7%, p = 0.005, vitamin D 14.3% versus 27.4%, p = 0.037 and folate deficiency 7.1% versus 28.6%, p= <0.001.) Post-diagnosis, 67.5% of the PCD patients chose a GFD. One-third of the patients who continued to eat gluten developed villous atrophy. CONCLUSION: The presentation of PCD and CD differ; however, mild enteropathy does not necessarily equate to mild symptoms. The GFD appears to be advantageous in symptomatic PCD.

Does reverse mentoring work in the NHS: a feasibility study of clinicians in practice.

OBJECTIVE: To assess the risks and benefits of reverse mentoring of consultants by junior doctors. DESIGN: A feasibility study divided into two phases: first a semistructured interview where performance of participating consultants was assessed by junior doctors and then a second phase allowing for feedback to be given on a one-to-one basis. Data collected through questionnaires with free text questions and Likert scores. SETTING: Tertiary teaching hospital in the UK. PARTICIPANTS: Six junior doctors (66.6% male, age range 31-40 years) and five consultants (80% male, age range 35-65 years and consultants for 5-20 years). INTERVENTION: Reverse mentoring session. MAIN OUTCOME MEASURE: The concerns and/or benefits of the process of reverse mentoring. Confidence was assessed in 7 domains: clinical practice, approach to juniors, approachability, use of technology, time management, strengths and areas for improvement using Likert scales giving a total out of 35. RESULTS: The most common concerns cited were overcoming the hierarchical difference and a selection bias in both mentors and mentees. However, no participant experienced this hierarchical difference through the reverse mentoring process and no relationships were negatively affected. Mentors became more confident in feeding back to seniors (23 vs 29 out of 35, p=0.04) most evident in clinical practice and areas to improve (3 vs 4 out of 5, p=0.041 and 3 vs 5 out of 5, p=0.041, respectively). CONCLUSION: We present the first study of reverse mentoring in an NHS clinical setting. Initial concerns with regard to damaged relationships and hierarchical gradients were not experienced and all participants perceived that they benefited from the process. Reverse mentoring can play a role in engaging and training future leaders at junior stages and provide a means for consultants to receive valuable feedback from junior colleagues.

Non-Responsive and Refractory Coeliac Disease: Experience from the NHS England National Centre.

We characterised the aetiology of non-responsive coeliac disease (NRCD) and provided contemporary mortality data in refractory coeliac disease (RCD) from our centre. We also measured urine gluten immunogenic peptides (GIPs) in patients with established RCD1 to evaluate gluten exposure in these individuals. METHODS: This was a longitudinal cohort study conducted in Sheffield, UK. Between 1998 and 2019, we evaluated 285 adult (≥16 years) patients with NRCD or RCD. Patients with established RCD1 and persisting mucosal inflammation and/or ongoing symptoms provided three urine samples for GIP analysis. RESULTS: The most common cause of NRCD across the cohort was gluten exposure (72/285; 25.3%). RCD accounted for 65/285 patients (22.8%), 54/65 patients (83.1%) had RCD1 and 11/65 patients (16.9%) had RCD2. The estimated 5-year survival was 90% for RCD1 and 58% for RCD2 (p = 0.016). A total of 36/54 (66.7%) patients with RCD1 underwent urinary GIP testing and 17/36 (47.2%) had at least one positive urinary GIP test. CONCLUSION: The contemporary mortality data in RCD2 remains poor; patients with suspected RCD2 should be referred to a recognised national centre for consideration of novel therapies. The high frequency of urinary GIP positivity suggests that gluten exposure may be common in RCD1; further studies with matched controls are warranted to assess this further.

Evidence-Based and Emerging Diet Recommendations for Small Bowel Disorders.

Diet plays a key role in the manifestation and severity of gastrointestinal symptoms, with increasing research interest on the role of diet in small bowel disorders. There are predominantly 3 small bowel conditions that have potential dietary interventions. Self-reported nonceliac gluten/wheat sensitivity is prevalent. Although gluten is believed to be a potential trigger for symptoms, other components of wheat may also be triggers, including fructans, alpha-amylase trypsin inhibitors, and wheat germ agglutinins. The diagnosis can be challenging, given the lack of validated biomarkers. A gluten-free diet that excludes the abovementioned triggers is the cornerstone of treatment; however, unlike celiac disease, there is uncertainty about the level of adherence or whether the gluten-free diet is a lifelong intervention. Several primary gastrointestinal disorders are associated with an increase in inflammatory cells including eosinophils. Diet seems to be an important driver of disease pathogenesis in eosinophilic gastroenteritis, with elimination and elemental diets showing promise in management, with further robust trials required. Small intestinal bacterial overgrowth is an example of microbial dysbiosis, with renewed interest in diet being postulated to cause an adaptive change of the microbes colonizing the small intestine. However, the diagnosis of small intestinal bacterial overgrowth is limited by a lack of sensitive and specific tests, with significant knowledge gaps in relation to therapeutic measures to manage and cure small intestinal bacterial overgrowth. Currently, antimicrobials are the established management option. There have been significant clinical advances in dietary interventions related to the small bowel, but this area is currently a novel and advancing field for both patients and clinicians.

Efficacy and Acceptability of Dietary Therapies in Non-Constipated Irritable Bowel Syndrome: A Randomized Trial of Traditional Dietary Advice, the Low FODMAP Diet, and the Gluten-Free Diet.

BACKGROUND & AIMS: Various diets are proposed as first-line therapies for non-constipated irritable bowel syndrome (IBS) despite insufficient or low-quality evidence. We performed a randomized trial comparing traditional dietary advice (TDA) against the low FODMAP diet (LFD) and gluten-free diet (GFD). METHODS: Patients with Rome IV-defined non-constipated IBS were randomized to TDA, LFD, or GFD (the latter allowing for minute gluten cross-contamination). The primary end point was clinical response after 4 weeks of dietary intervention, as defined by ≥50-point reduction in IBS symptom severity score (IBS-SSS). Secondary end points included (1) changes in individual IBS-SSS items within clinical responders, (2) acceptability and food-related quality of life with dietary therapy, (3) changes in nutritional intake, (4) alterations in stool dysbiosis index, and (5) baseline factors associated with clinical response. RESULTS: The primary end point of ≥50-point reduction in IBS-SSS was met by 42% (n = 14/33) undertaking TDA, 55% (n = 18/33) for LFD, and 58% (n = 19/33) for GFD (P = .43). Responders had similar improvements in IBS-SSS items regardless of their allocated diet. Individuals found TDA cheaper (P < .01), less time-consuming to shop (P < .01), and easier to follow when eating out (P = .03) than the GFD and LFD. TDA was also easier to incorporate into daily life than the LFD (P = .02). Overall reductions in micronutrient and macronutrient intake did not significantly differ across the diets. However, the LFD group had the greatest reduction in total FODMAP content (27.7 g/day before intervention to 7.6 g/day at week 4) compared with the GFD (27.4 g/day to 22.4 g/day) and TDA (24.9 g/day to 15.2 g/day) (P < .01). Alterations in stool dysbiosis index were similar across the diets, with 22%-29% showing reduced dysbiosis, 35%-39% no change, and 35%-40% increased dysbiosis (P = .99). Baseline clinical characteristics and stool dysbiosis index did not predict response to dietary therapy. CONCLUSIONS: TDA, LFD, and GFD are effective approaches in non-constipated IBS, but TDA is the most patient-friendly in terms of cost and convenience. We recommend TDA as the first-choice dietary therapy in non-constipated IBS, with LFD and GFD reserved according to specific patient preferences and specialist dietetic input. CLINICALTRIALS: gov: NCT04072991.

Diagnostic Yield of Colonoscopy in Patients With Symptoms Compatible With Rome IV Functional Bowel Disorders.

BACKGROUND & AIMS: There is little data on the diagnostic yield of colonoscopy in patients with symptoms compatible with functional bowel disorders (FBDs). Previous studies have only focused on diagnostic outcomes of colonoscopy in those with suspected irritable bowel syndrome using historic Rome I-III criteria, whilst having partially assessed for alarm features and shown markedly conflicting results. There is also no colonoscopy outcome data for other FBDs, such as functional constipation or functional diarrhea. Using the contemporaneous Rome IV criteria we determined the diagnostic yield of colonoscopy in patients with symptoms compatible with a FBD, stratified diligently according to the presence or absence of alarm features. METHODS: Basic demographics, alarm features, and bowel symptoms using the Rome IV diagnostic questionnaire were collected prospectively from adults attending out-patient colonoscopy in 2019. Endoscopists were blinded to the questionnaire data. Organic disease was defined as the presence of inflammatory bowel disease, colorectal cancer, or microscopic colitis. RESULTS: 646 patients fulfilled symptom-based criteria for the following Rome IV FBDs: IBS (56%), functional diarrhea (27%) and functional constipation (17%). Almost all had alarm features (98%). The combined prevalence of organic disease was 12%, being lowest for functional constipation and IBS-constipation (∼6% each), followed by IBS-mixed (∼9%), and highest amongst functional diarrhea and IBS-diarrhea (∼17% each); p = .005. The increased prevalence of organic disease in diarrheal versus constipation disorders was accounted for by microscopic colitis (5.7% vs. 0%, p < .001) but not inflammatory bowel disease (7.2% vs. 4.0%, p = .2) or colorectal cancer (4.2% vs. 2.3%, p = .2). However, 1-in-4 chronic diarrhea patients - conceivably at risk for microscopic colitis - did not have colonic biopsies taken. Finally, only 11 of 646 (2%) patients were without alarm features, in whom colonoscopy was normal. CONCLUSIONS: Most patients with symptoms of FBDs who are referred for colonoscopy have alarm features. The presence of organic disease is significantly higher in diarrheal versus constipation disorders, with microscopic colitis largely accounting for the difference whilst also being a missed diagnostic opportunity. In those patients without alarm features, the diagnostic yield of colonoscopy was nil.

Adult celiac disease with persistent IBS-type symptoms: a pilot study of an adjuvant FODMAP diet.

AIM: This pilot study assessed the benefits of an adjuvant low FODMAP diet (LFD) in adult CD patients established on GFD who had a normal remission biopsy. BACKGROUND: Patients with biopsy-proven adult celiac disease (CD) may have on-going gastrointestinal symptoms despite adherence to a gluten-free diet (GFD). Functional gut symptoms, including irritable bowel syndrome (IBS), is one cause of persistent symptoms in CD patients. METHODS: Twenty-five adult CD patients who were adherent to the GFD were recruited. These patients had histologically normal villi on their remission biopsy. A specialist dietitian then offered an adjuvant LFD. Symptom response was assessed using the Gastrointestinal Symptom Rating Scale (GSRS) from baseline to follow up. RESULTS: Of the 25 CD patients in remission with concurrent IBS, 9 did not wish to pursue the LFD, and 1 had incomplete data. Fifteen patients completed a minimum of four weeks on the LFD (mean age 44 ± 17.3; range 43.2 years; median duration of CD follow-up 7.2 years). Global relief of gut symptoms was reported by 8/15 patients (53% p = 0.007). Significant reductions in abdominal pain (p <0.01), distension (p < 0.02), and flatulence (p <0.01) were demonstrated. CONCLUSION: This is the first study to demonstrate that an adjunct LFD is an effective dietary treatment for concurrent IBS in adult CD patients with biopsy-confirmed remission. Such patients should be seen by a specialist dietitian to ensure nutritional adequacy and appropriate reintroduction of FODMAP-containing foods.

Clinical classification and long-term outcomes of seronegative coeliac disease: a 20-year multicentre follow-up study.

BACKGROUND: Seronegative coeliac disease is poorly defined. AIMS: To study clinical phenotypes and long-term outcomes of seronegative coeliac disease in a multicentre cohort over 20 years. METHODS: Seronegative coeliac disease was diagnosed in HLA-DQ2/DQ8-positive patients with villous atrophy (VA), negative IgA endomysial (EmA), tissue transglutaminase (tTG) and deamidated-gliadin antibodies (DGP), clinical and histological response to a gluten-free diet (GFD), and no alternative causes for VA. In patients with IgA deficiency, coeliac disease was diagnosed through VA, positive IgG EmA/tTG/DGP and clinical/histological response to a GFD (coeliac disease+IgAd). Patients with seropositive coeliac disease served as controls. RESULTS: Of 227 patients previously diagnosed with seronegative coeliac disease, true seronegative coeliac disease was confirmed in 84, coeliac disease+IgAd in 48, and excluded in 55. Lack of follow-up duodenal biopsy precluded diagnosing seronegative coeliac disease in 40 patients. 2084 patients with seropositive coeliac disease served as controls. True seronegative coeliac disease had more severe symptoms at diagnosis and a higher risk of complications (HR 10.87, 95% CI 6.11-19.33, P < 0.001) and mortality (HR 2.18, 95% CI 1.12-4.26, P < 0.01) than seropositive coeliac disease. There were no differences between true seronegative coeliac disease and coeliac disease+IgAd. On multivariate analysis, age at diagnosis, lack of clinical response to a GFD, true seronegative coeliac disease, coeliac disease+IgAd, and classical presentation predicted complications. Age at diagnosis, complications and absence of clinical response to a GFD predicted mortality. CONCLUSIONS: Seronegative coeliac disease has a more aggressive disease phenotype than seropositive coeliac disease. These data argue against over-reliance on serology for the diagnosis of coeliac disease and support a strict clinical and histologic follow-up in seronegative coeliac disease.

The low FODMAP diet for IBS; A multicentre UK study assessing long term follow up.

BACKGROUND: The low FODMAP diet (LFD) is effective in managing irritable bowel syndrome (IBS) in the short term. This study assessed the long-term effect of the LFD on symptoms, nutritional composition and socialising. METHODS: Patients with IBS who received dietetic-led LFD advice were approached at long term follow up (>6 months post LFD advice) from six centres across the United Kingdom. Participants completed questionnaires assessing gastrointestinal symptoms, adherence, nutritional intake, dietary acceptability and food related quality of life (QOL). RESULTS: 205 participants completed the study, with a mean follow up of 44 months (3.7 years). Adequate symptom relief was noted in 60% of individuals at long term follow up, with 76% being on the personalisation phase of the LFD (pLFD). Mean nutritional intake did not differ between individuals on the pLFD versus habitual diet, with no difference in fructan intake (2.9 g/d vs 2.9 g/d, p = 0.96). The majority (80%) of individuals on the pLFD consumed specific 'free-from' products at the long term, with the purchase of gluten or wheat free products being the commonest (68%). CONCLUSION: The majority of patients follow the pLFD in the long term, with a large proportion purchasing gluten or wheat free products to manage their symptoms.

What is the Optimal Method Assessing for Persistent Villous Atrophy in Adult Coeliac Disease?

BACKGROUND AND AIMS: Methods of assessing gluten-free diet (GFD) adherence in adults with coeliac disease (CD) include serological testing, dietitian evaluation, questionnaires and repeat duodenal biopsies. Persisting villous atrophy (VA) is associated with CD complications, however gastroscopy with biopsies is expensive and invasive. This study aimed to assess the abilities of a duodenal bulb (D1) biopsy and the Celiac Dietary Adherence Test (CDAT) to detect persisting VA in adults with CD. METHODS: A prospective observational study of adult CD patients referred for follow-up duodenal biopsies was performed. Quadrantic biopsies were taken from the second part of the duodenum (D2), in addition to a D1 biopsy. Patients underwent follow-up serological testing, and completed the CDAT and Biagi Score. These non-invasive adherence markers were compared against duodenal histology. RESULTS: 368 patients (mean age 51.0 years, 70.1% female) had D1 and D2 biopsies taken at follow-up gastroscopy. Compared to D2 biopsies alone, additional D1 biopsies increased detection of VA by 10.4% (p<0.0001). 201 patients (mean age 50.3 years, 67.7% female) completed adherence questionnaires and serology. When detecting VA, sensitivities and specificities of these markers were 39.7% and 94.2% for IgA- tTG, 38.1% and 96.4% for IgA-EMA, 55.6% and 52.2% for CDAT and 20.6% and 96.4% for the Biagi score. CONCLUSIONS: Bulbar biopsies increase detection of persisting VA by 10.4%. Serology, CDAT and Biagi performed poorly when predicting VA. The gold standard for predicting persisting VA remains repeat biopsy.

An update on coeliac disease from the NHS England National Centre for Refractory Coeliac Disease.

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.

Increased psychological distress and somatization in patients with irritable bowel syndrome compared with functional diarrhea or functional constipation, based on Rome IV criteria.

BACKGROUND: The Rome IV criteria for disorders of gut-brain interaction define irritable bowel syndrome (IBS) as a functional bowel disorder associated with frequent abdominal pain of at least 1 day per week. In contrast, functional diarrhea (FD) and functional constipation (FC) are relatively painless. We compared differences in mood and somatization between Rome IV IBS and FC/FD. METHODS: A total of 567 patients with Rome IV defined IBS or FD/FC completed a baseline questionnaire on demographics, abdominal pain frequency, mood (hospital anxiety and depression scale, HADS), and somatization (patient health questionnaire, PHQ-12). The primary analysis compared differences in mood and somatization between IBS and FC/FD, and the relative influence of abdominal pain frequency on these extra-intestinal symptoms. The secondary analysis evaluated differences across individual IBS subtypes, and also between FC and FD. KEY RESULTS: Patients with IBS-in comparison to those with FC/FD-had significantly higher mean PHQ-12 somatization scores (9.1 vs. 5.4), more somatic symptoms (6.0 vs. 4.3), abnormally high somatization levels (16% vs. 3%), higher HADS score (15.0 vs. 11.7), and clinically abnormal levels of anxiety (38% vs. 20%) and depression (17% vs. 10%). Increasing abdominal pain frequency correlated positively with PHQ-12, number of somatic symptoms, and HADS; p < 0.001. No differences in mood and somatization scores were seen between individual IBS subtypes, and nor between FC and FD. CONCLUSION & INFERENCES: Based on the Rome IV criteria, IBS is associated with increased levels of psychological distress and somatization compared with FD or FC. Patients reporting frequent abdominal pain should be comprehensively screened for psychosomatic disorders, with psychological therapies considered early in the disease course.

Persisting Villous Atrophy and Adherence in Celiac Disease: What Does the Patient Want? What Should a Clinician Advise?

ABSTRACT: Adherence to a gluten-free diet in celiac disease remains challenging. Clinicians may view mucosal healing as crucial. From the patient's perspective, avoidance of an invasive upper endoscopy may be desirable. A fundamental misconception is that noninvasive tools including symptoms, serology, dietary adherence questionnaires, and novel gluten immunogenic peptides may detect ongoing villous atrophy rather than assess adherence. Duodenal biopsies are the only reliable method for assessment of mucosal healing-however, we as clinicians should provide patients with the uncertainties of this approach allowing them to make an informed decision on an individual basis.

National survey evaluating the provision of gastroenterology dietetic services in England.

Aims: The aim of the study was to assess the provision of dietetic services for coeliac disease (CD), irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Methods: Hospitals within all National Health Service trusts in England were approached (n=209). A custom-designed web-based questionnaire was circulated via contact methods of email, post or telephone. Individuals/teams with knowledge of gastrointestinal (GI) dietetic services within their trust were invited to complete. Results: 76% of trusts (n=158) provided GI dietetic services, with responses received from 78% of these trusts (n=123). The median number of dietitians per 100 000 population was 3.64 (range 0.15-16.60), which differed significantly between regions (p=0.03). The most common individual consultation time for patients with CD, IBS and IBD was 15-30 min (43%, 44% and 54%, respectively). GI dietetic services were delivered both via individual and group counselling, with individual counselling being the more frequent delivery method available (93% individual vs 34% group). A significant proportion of trusts did not deliver any specialist dietetic clinics for CD, IBS and IBD (49% (n=60), 50% (n=61) and 72% (n=88), respectively). Conclusion: There is an inequity of GI dietetic services across England, with regional differences in the level of provision and extent of specialist care. Allocated time for clinics appears to be insufficient compared with time advocated in the literature. Group clinics are becoming a more common method of dietetic service delivery for CD and IBS. National guidance on GI dietetic service delivery is required to ensure equity of dietetic services across England.
