Gluten-free Diet Adherence Research Articles

Exploring the link between celiac disease and obesity: a potential role of gut microbiome.

In today's age, celiac disease (CD) is no longer solely characterized by chronic diarrhea in a malnourished child. Obesity is gradually being acknowledged as part of CD's clinical course. Both conditions have been linked to alterations of gut microbiome. Given the difficulty of strict gluten-free diet adherence, there is a need for less restrictive adjunctive therapies. We aimed to investigate the prevalence of obesity in patients diagnosed with CD with the goal of developing new therapeutic approaches. Baseline data from the National Institute of Health's All of Us Research Program, was used to evaluate the relationship between CD and obesity. A retrospective cohort study was conducted where groups of individuals with CD and without CD were matched by age range and health surveys. Statistical analysis with odds ratios (OR) with 95% confidence intervals (CI) were reported. The prevalence of obesity was 32.6% in the CD group compared to 18.4% in the control group (OR, 2.111; 95% CI, 1.914-2.328; P< 0.0001). Women accounted for a greater population of patients with CD and obesity. The largest percentage of patients with CD and obesity were older than 65 years. The highest percentage of individuals in both the experimental and control groups were white, followed by African Americans. Our data shows a significant association between CD and increased prevalence of obesity. These results warrant further investigation into microbial changes and dietary exposures that affect the pathogenesis of both diseases.

Food insecurity impacts diet quality and adherence to the gluten-free diet in youth with celiac disease.

Celiac disease (CD) is an autoimmune gastrointestinal disorder that requires a strict lifelong gluten-free diet (GFD). Gluten-free (GF) foods are more expensive and less readily accessible than gluten-containing foods, contributing to an increased risk for food insecurity (FI). The study aimed to determine associations between GF-FI, sociodemographic risk factors and child dietary adherence and diet quality (DQ). A 26-item, cross-country online survey was administered through social media to parents of children with CD on the GFD. The survey elicited household and CD child sociodemographic and clinical characteristics (e.g., duration of CD), measures of household FI, child DQ and GFD adherence, and parents' concerns related to GF food. Household GF-FI was evaluated using the validated Hunger Vital Sign™ and the US Department of Agriculture Six-Item Short Form Household Food Security Survey Module. GF-FI occurred in 47% of households with children with CD with >30% reporting low to very low food security. Sociodemographic risk factors identified included lower income, renters, rural residency, single-parental households, and having children with additional dietary restrictions (p < 0.001). Regardless of FI status, a majority of households reported experiencing significantly higher GF food expenditure. GF-FI was associated with reduced adherence to the GFD, increased consumption of processed GF food, and lower intakes of fresh fruits and vegetables and GF grains among children with CD (p < 0.05). GF-FI is prevalent in this multiethnic cohort of households with CD children and is associated with worsening DQ and GFD adherence. Policy interventions are urgently needed to address GF-FI.

Social Adversities Associate with Worse Disease Control in Pediatric Celiac Disease

To characterize how social adversities influence disease control in children with celiac disease (CeD). We conducted a cross-sectional analysis of data from 325 eligible children ≤18years old with CeD enrolled between 2015 through 2023 into iCureCeliac, a patient-centered US registry for CeD. We evaluated the associations between financial insecurity, social stigmatization, decreased health knowledge, and mental health comorbidity with 2 validated patient-reported outcomes on disease activity and gluten-free diet adherence: celiac symptom index and CeD adherence test, respectively. We used multivariable logistic and linear regression analysis to adjust for race, primary spoken language, and socioeconomic status. Among 325 children with available financial insecurity data, the median age was 11years (IQR 8, 15), 67% were female, and 88% were White. In multivariable logistic regression, the odds of elevated disease activity among children with financial insecurity, social stigmatization, decreased health knowledge, and mental health comorbidity were 2.6 (95% CI 0.9, 8.0; P=.09), 2.8 (95% CI 1.6, 5.1; P<.001), 4.8 (95% CI 2.4, 9.8; P<.001), and 1.9 (95% CI 1.1, 3.3; P=.03), respectively. For insufficient dietary adherence, the respective odds were 1.6 (95% CI 0.5, 4.7; P=.43), 3.3 (95% CI 1.7, 6.5; P<.001), 2.9 (95% CI 1.5, 5.7; P=.002), and 2.3 (95% CI 1.2, 4.2; P=.01). Statistically significant associations in logistic regression aligned with results of linear models. Social stigmatization, decreased health knowledge, and mental health comorbidity were associated with worse disease control in pediatric CeD. Targeted interventions aimed at addressing these social adversities may improve disease activity and dietary adherence.

Assessing the Impact of a Gluten-Free Diet on Celiac Disease Symptoms in Children: A Comprehensive Review.

Celiac disease, a serious autoimmune disease, is triggered by the ingestion of gluten. It is associated with many gastrointestinal and extraintestinal symptoms. The cornerstone of treatment is a strict gluten-free diet (GFD). This paper collected studies that were screened between the 15th and 25th of June 2024 and were searched for from many databases and registers, including PubMed, Medline, ClinicalTrials.gov, Cochrane Library, Europe PMC, and EBSCO Open Dissertations. We have included the 12 most relevant studies that examined the effects of GFD adherence among pediatric patients with celiac disease. Evidence suggests that a GFD caused notable improvements in liver function, growth metrics, and quality of life indices. Extraintestinal symptoms such as cardiac dysfunctions and obstructive sleep apnea also showed compelling improvement. We conclude that there are substantial advantages of a GFD in children with celiac disease and call for the need for personal nutritional support to address nutritional deficiencies and long-term studies and comprehensive strategies to optimize treatment outcomes and improve the quality of life for affected children.

Clinical presentation and factors associated with gluten exposure in children with celiac disease.

The prevalence of celiac disease (CeD) is increasing, yet it is still underdiagnosed, in part because of its heterogeneous presentation. Diagnostic criteria are evolving and management with strict adherence to a gluten-free diet is challenging for many. We aimed to characterize the clinical presentation of CeD among a large multicenter cohort of pediatric patients and to identify factors associated with gluten-free diet adherence. Patients with CeD aged 0-18 years were recruited from 11 United States health centers. Parents completed surveys about gluten-free diet adherence and patient electronic health records were reviewed. Logistic regression analyses were performed to identify risk factors associated with gluten exposure. Charts were reviewed for 460 children with a median age of 6.4 years. Abdominal pain was reported in 57% of the cohort, but diverse symptoms were identified. Parent surveys were completed for 455 participants. Sixty-five (14%) participants were at high risk for gluten exposure based on parental reports of weekly or daily gluten exposure or eating gluten by choice in the past year. Participants under the age of 5 years had a lower risk of gluten exposure, while participants without repeat serology testing 18 months after initial diagnosis were at higher risk of gluten exposure. In a large, multicenter cohort of pediatric CeD patients, clinical presentation is highly variable, necessitating a high index of suspicion to make a diagnosis. Parent surveys indicate that 14% of patients are at high risk of gluten exposure, with patient age and lack of close follow-up associated with gluten-free diet adherence.

Gluten-Free Diet Adherence Tools for Individuals with Celiac Disease: A Systematic Review and Meta-Analysis of Tools Compared to Laboratory Tests.

This systematic review aimed to find the tool that best predicts celiac individuals' adherence to a gluten-free diet (GFD). The Transparent Reporting of Multivariable Prediction Models for Individual Prognosis or Diagnosis (TRIPOD-SRMA) guideline was used for the construction and collection of data from eight scientific databases (PubMed, EMBASE, LILACS, Web of Science, LIVIVO, SCOPUS, Google Scholar, and Proquest) on 16 November 2023. The inclusion criteria were studies involving individuals with celiac disease (CD) who were over 18 years old and on a GFD for at least six months, using a questionnaire to predict adherence to a GFD, and comparing it with laboratory tests (serological tests, gluten immunogenic peptide-GIP, or biopsy). Review articles, book chapters, and studies without sufficient data were excluded. The Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies (CHARMS) was used for data collection from the selected primary studies, and their risk of bias and quality was assessed using the Prediction Risk of Bias Assessment Tool (PROBAST). The association between the GFD adherence determined by the tool and laboratory test was assessed using the phi contingency coefficient. The studies included in this review used four different tools to evaluate GFD adherence: BIAGI score, Coeliac Dietary Adherence Test (CDAT), self-report questions, and interviews. The comparison method most often used was biopsy (n = 19; 59.3%), followed by serology (n = 14; 43.7%) and gluten immunogenic peptides (GIPs) (n = 4; 12.5%). There were no significant differences between the interview, self-report, and BIAGI tools used to evaluate GFD adherence. These tools were better associated with GFD adherence than the CDAT. Considering their cost, application time, and prediction capacity, the self-report and BIAGI were the preferred tools for evaluating GFD adherence.

Eating disorders, body image dissatisfaction and their association with gluten-free diet adherence among patients with celiac disease

BackgroundConsidering the higher prevalence of psychological problems in patients with Celiac disease (CD), the current study aims to assess the prevalence of eating disorders (EDs) and body image disturbance in patients with CD and examine the possible correlation between EDs, body image dissatisfaction and distortion, and gluten-free diet (GFD) adherence in these patients.MethodsIn this cross-sectional study, 217 patients with CD (18–55 years old) were recruited randomly from the CD registry database. EDs and body image issues were assessed using the 26-item Eating Attitude Test (EAT-26) and Stunkard Figure Rating Scale (FRS), respectively. Adherence to GFD was evaluated by the Celiac Dietary Adherence Test (CDAT) questionnaire.ResultsThe prevalence of EDs was 43.5%. Furthermore, the prevalence of body dissatisfaction and distortion was 65.9% and 41.1%, respectively. The logistic regression demonstrated a significant negative association between adherence to the GFD and EDs (OR = 2.09, 95% CI: 1.11–3.91, P = 0.022). However, there was no significant association between following GFD and body image dissatisfaction (OR = 1.70, CI: 0.92–3.17, P = 0.090), and distortion (OR = 0.65, CI: 0.36–1.18, P = 0.163).ConclusionConsidering the high prevalence of EDs in patients with CD and owing to the inverse association between EDs and GFD adherence, nutritionists should consider the psychological barriers in adhering to a GFD when consulting patients with CD.

The primary nutritional approach in pediatric celiac disease: a mini-review

Background: Celiac disease (CD) is chronic small bowel inflammation with villous atrophy, consequently, an immune-mediated disorder triggered by ingesting Gluten in wheat, barley, and rye in genetically susceptible individuals. Aims: Summarize the fundamental principles for managing the diet of patients with CD. This Mini-Review using relevant articles in PubMed's online databases followed the medical keywords Celiac Disease, Gluten, gluten-free diet, nutritional approach, and diet adherence. The institution's Ethics Committee has waived the need to review the ethical aspects of this text. The cornerstone of the treatment is the lifelong adherence to a Gluten-Free Diet (GFD). This dietary regimen, which forms the basis of the patient's treatment, requires eliminating all food components containing Gluten and its derivatives from the diet. However, the treatment approach has changed from focusing on food avoidance to a wide-ranging evaluation of the various factors influencing the dietary choices in the patient's life. The Global Approach to the Follow-up of Celiac Disease is based on 1) control of symptomatology and dietary adherence; 2) improving emotional and social wellness in treating CD patients, with the active involvement of a psychologist; and 3) ensuring successful education of both the child and the family about its management. Indeed, the impact of CD extends beyond the patient and affects the well-being of caregivers and 4) evaluate socioeconomic burden, considering that Gluten-free food products remain significantly more expensive than gluten-containing equivalents with variable availability. So, the GFD is the primary treatment for CD, and difficulties in managing the Disease can lead to impaired Quality of Life. In conclusion, strict adherence to the GFD is imperative, requiring a multidisciplinary team involving physicians, dietitians, and psychologists on a regular visit schedule to assess dietary adherence and avoid long-term complications.

Adherence to the Gluten-Free Diet Role as a Mediating and Moderating of the Relationship between Food Insecurity and Health-Related Quality of Life in Adults with Celiac Disease: Cross-Sectional Study.

This cross-sectional study aimed to estimate the relationship between food insecurity (FI) and health-related quality of life (HRQoL) in patients with celiac disease (CD) and assess whether this relationship is mediated or moderated by adherence to the gluten-free diet (GFD). The results of 1162 samples of patients diagnosed with CD showed that 8.3% of individuals who have a combined score of less than 13 exhibited excellent or very good adherence to the GFD. Furthermore, moderate and fair to poor adherence to the GFD was demonstrated, respectively and 71.9% of the patients had poor HRQoL levels. A significant and moderate positive correlation between FI and GFD adherence (r = 0.489) was found, indicating that 24% of the variance in FI is shared with GFD adherence. The patients' gender, marital status, and monthly income made statistically significant contributions to the prediction (p < 0.05). Females had significantly lower HRQoL scores than males (B = -4.619, 95% CL: -6.08, -3.16) after holding all other variables constant. In conclusion, FI is mediated by GFD adherence to HRQoL. Moreover, a significant total effect relation was found between HRQoL and both FI and GFD adherence, suggesting that lowering symptoms and complications associated with CD may reduce the impact of FI on HRQoL.

One-Year Outcomes Among Children Identified With Celiac Disease Through a Mass Screening Program

Celiac disease (CD) mass screening remains controversial in part because of a paucity of data to support its benefit. The Autoimmunity Screening for Kids study is a mass screening study for pediatric CD and type 1 diabetes in Colorado. This study prospectively follows up children ages 1 to 17 years who screened positive for tissue transglutaminase IgA autoantibodies in the Autoimmunity Screening for Kids study subsequently referred for diagnostic evaluation. Children diagnosed with CD by biopsy or serologic criteria were included in this study. Evaluation at baseline and 12 month follow-up evaluation included demographics, laboratory studies, symptoms, health-related quality of life, anxiety/depression, and gluten-free diet adherence. Paired Student t test, chi-square, and Wilcoxon sign rank tests compared baseline and follow-up data. For symptom scores, odds of improvement were assessed. Of the 52 children with CD enrolled, 42 children completed 12-month follow-up evaluation. On the symptom questionnaire completed at diagnostic evaluation, 38 of 42 children reported 1 or more symptoms. CD mean symptom severity and frequency scores improved from baseline to follow-up evaluation (P < .001). Reported health-related quality of life scores improved among caregivers (P= .002). There was no significant change in reported anxiety or depression. Iron deficiency without anemia was common at baseline (21 of 24 children; 87.5%) and normalized at follow-up evaluation (11 of 21 children; 52.3%). Twenty-six of 28 families reported good or excellent gluten-free diet adherence. This novel study of children with CD identified through a mass screening program demonstrated improvement in symptoms, quality of life, and iron deficiency after 1 year follow-up evaluation. This demonstrates that there may be benefit to CD mass screening.

Gluten-free diet adherence in pediatric celiac patients: Evaluating CDAT questionnaire and test for gluten detection in urine.

This study aimed to evaluate the contributions of the Adapted Celiac Dietary Adherence Test (CDAT) and the Rapid Urinary Gluten Detection Test (u-GIP) in assessing gluten-free diet adherence in children and adolescents with celiac disease. Fifty-four celiac patients from two pediatric gastroenterology outpatient clinics affiliated with university hospitals were evaluated. The original CDAT was adapted for children through a transcultural process, and the original cutoff point was adopted to define adherence. A single examiner carried out the u-GIP test in fresh urine samples. Sociodemographic and clinical factors and family food security status were also evaluated. A total of 88.9% of participants (confidence interval [CI]: 77.4-95.8; p<0.001) adhered to the gluten-free diet, as determined by the adapted CDAT score, while 87.0% (CI: 75.1-94.6; p<0.001) had negative u-GIP results. Among the 48 children adhering to the CDAT, six exhibited positive u-GIP results in a urine sample. Of the six nonadherent participants, only one had a positive u-GIP result. Notably, none of the children and adolescents with celiac disease who tested positive for u-GIP reported symptoms on the day of testing, and their growth rates remained stable. Even celiac children and adolescents adhering to the CDAT questionnaire may show a positive u-GIP in a single measurement without accompanying symptoms or growth impairment. The u-GIP could be helpful in complementary tests in specific situations, such as for patients who exhibit compliant behavior but still experience symptoms or maintain persistent positive serology.

Health-related quality of life among celiacs in Portugal: a comparison between general and specific questionnaires.

This study aimed to compare the 36-Item Short Form Survey Instrument version 2 (SF-36-v2) (generic) and Celiac Disease Questionnaire (CDQ) (specific) questionnaires used to evaluate the quality of life (QoL) in celiac Portuguese adult individuals. This cross-sectional study used non-probabilistic sampling based on Portuguese celiac patients who accessed the online survey in 2022. The online data collection used a self-reported instrument composed of three parts: (i) socioeconomic, health, and gluten-free diet (GFD) adherence questions; (ii) SF-36 v2 - Portuguese version (generic questionnaire) and (iii) Celiac Disease Questionnaire (CDQ) (specific questionnaire). A total of 234 individuals who accessed the survey completed the questionnaire. Seven of the eight SF-36 domains positively correlated to the specific questionnaire CDQ. The "General Health" domain (domain 4) showed a negative correlation with the CDQ. Differences in content between the two instruments might be able to explain this finding since the CDQ explores issues regarding the specificities of celiac disease (CD) and the lifelong GFD burden. About half of the sample from this study displayed poor diet adherence, it is possible that the SF-36 could not reflect the impact of CD treatment - the complete elimination of gluten from the diet - on patients' health. Therefore, this issue should be carefully evaluated in future research. Specific validated questionnaires for CD individuals, such as the CDQ, contemplate social, economic, and clinical variables that permeate the patient's life context. Therefore, these instruments may be more suitable for evaluating QoL in this public. However, using a general questionnaire such as the SF-36 would be indicated for comparing QOL between celiac patients and the general population or even between CD and other disease individuals. In this case, we recommend assessing GFD compliance for control parallelly.

A significant increase in anthropometric indices during long-term follow-up of pediatric patients with celiac disease, with no endocrine disorders.

Celiac disease (CeD) is likely to be associated with growth impairment and poor weight gain. However, long-term growth patterns following diagnosis are poorly characterized. We evaluated long-term anthropometric changes in a large cohort of pediatric patients with CeD. A retrospective chart review of patients diagnosed with CeD between 1999 and 2018 was conducted. Demographic and clinical data were collected, and anthropometrics were analyzed from diagnosis and throughout follow-up. The study included 500 patients (59.8% females, median (IQR) age at diagnosis 5.7 (3.7-8.9) years), with a mean follow-up of 5.5 (range 1.5-16.2) years. Weight, height, and BMI Z-score-for-age (WAZ, HAZ, and BMIZ) increased significantly from a mean (± SD) of - 0.82 (± 1.21), - 0.73 (± 1.16), and - 0.32 (± 1.11) at diagnosis to - 0.41 (± 1.23), - 0.45(± 1.16), and - 0.17 (± 1.14) at last follow-up, respectively (p < 0.001 for WAZ and HAZ and p = 0.002 for BMIZ). The largest improvements were observed in patients diagnosed before 3years of age (p < 0.01). Patients for whom the final adult height was available (n = 86) improved from HAZ mean (± SD) - 0.89 ± 1.37 at diagnosis to - 0.51 ± 1.28 at adulthood measurement, p < 0.05. Wasting was present in 19.7% and stunting in 16.4% of the cohort at diagnosis and normalized in 77.3% and 64.8%, respectively, within a median (IQR) time of 0.79 (0.42-4.24) and 2.3 (0.72-6.02) years, respectively. Gluten-free diet adherence and frequency of visits were not associated with normalization of wasting or stunting in all age groups. Conclusion: Over a long-term follow-up, pediatric patients with CeD demonstrate significant increases in weight, height, and BMI-for-age. Younger age at diagnosis is associated with greater improvement in weight and linear growth, emphasizing the importance of early diagnosis of CeD. What is Known: • Celiac disease (СeD) is likely to be associated with growth impairment and poor weight gain. • Long-term changes in anthropometric indices after diagnosis of CeD are not well characterized. What is New: • Over a long-term follow-up, pediatric patients with CeD demonstrate significant increases in weight, height, and BMI-for-age. • Young age at diagnosis is associated with larger improvement in weight and linear growth.

A167 ASSESSMENT OF QUALITY OF LIFE AMONG CHILDREN WITH CELIAC DISEASE IN JORDAN

Abstract Background Celiac disease has a profound impact on the daily lives of patients who are diagnosed with this chronic disease and affected by its myriad of clinical implications. Thus, health-related quality of life (HrQol) surveys proved invaluable in assessing children with this condition. Aims We aimed to assess HrQol of children with celiac disease in Jordan. In addition to the effect of gender, diet-restriction compliance compliance and the concomitant occurance of other chronic illnesses on the HrQol in our cohort. Methods A cross-sectional study of all children registered with the Celiac Disease Care Providers Society (CDPS) were asked to fill an online quality of life questionnaire. The Arabic version of the Kidscreen-52 questionnaire, with 10 domains was adopted. Data was analyzed using descriptive statistics and average T-scores across 10 health domains. Data was compared to previously published international norms.The sample was divided into four cohorts based on concomitant disorders, disease duration, adherence to gluten free diet (GFD), and growth issues. Independent sample t-tests, p-values, and Cohen's ds were determined for each cohort. Subcohorts were compared to each other. Results Out of 400 children registered with the society. 126(31.5%) patients responded. Male celiac patients performed worse in six health domains compared to the general population: moods and emotions, self-perception, bullying, psychological well-being, social support, and financial resources. The last three of which showed poorer performance in female celiacs too. Moods and emotions and self-perception were significantly worse in males with chronic disease and without GFD adherence. Females with growth issues performed worse in school environment and financial resources. Conclusions The study reveals a significant reduction in Hrqol in celiac patients compared to healthy individuals, a first in Jordan. This highlights the need for education initiatives for patients and physicians, as well as campaigns for national support for GFD. Further research is needed to identify other contributing factors and what interventions at community level should be taken. Funding Agencies None

A19 THE IMPACT OF FOOD INSECURITY ON ADHERENCE TO A GLUTEN-FREE DIET IN THE ADULT CELIAC DISEASE POPULATION ATTENDING A DEDICATED CELIAC CLINIC

Abstract Background A strict gluten-free diet (GFD) is currently the only treatment for celiac disease (CeD), but a GFD can be inconvenient and expensive. CeD patients who are food insecure (FI) face threats to GFD adherence, overall health, and quality of life. Aims To evaluate the prevalence of FI in patients with CeD attending a dedicated Adult Celiac Disease Clinic (ACDC) at an academic hospital and to examine the relationship between FI and GFD adherence, quality of life and various gastrointestinal symptoms. Methods Patients were invited to participate in the CeD registry when they attended the ACDC; those who agreed to participate then provided verbal and signed consent. Patients had the option to complete the CeD registry forms in the clinic on an iPad or at home using a card with a QR code and a unique ID to access the online CeD registry. The CeD registry uses REDCap (v. 11.1, 2021, US) and includes six validated questionnaires (Celiac Diet Adherence Test (CDAT), Celiac Disease Quality of Life Questionnaire (CD QoL), Celiac Symptom Index (CSI), Gastrointestinal Symptom Rating Scale (GSRS), Hospital Anxiety and Depression Scale (HADS), and Household Food Security Survey Module (HFSSM)). Continuous data are expressed as mean (SD), and categorical data as proportions of patients. The chi-squared test with Fisher correction and t-test were used to assess differences between groups. Results A total of 653 patients attended the ACDC from November 2, 2022, to September 20, 2023, and 411 patients were invited to participate in this study. Of them, 204 completed the CeD registry. Food insecurity was identified in 16% of CeD patients, of whom 11 (5%) were marginally FI, 16 (8%) were moderately FI, and 7 (3%) were severely FI. Compared to CeD patients who are food secure, a greater proportion of FI CeD patients reported nonadherence to GFD (26/34 vs 70/170; p&amp;lt;0.001), reduced QoL (32/34 vs 98/170; p&amp;lt;0.001), greater anxiety (27/34 vs 84/170; p=0.001) and greater depression (13/34 vs 26/170; p=0.004) compared with normal values. CeD patients with FI also reported lower QoL [61.0(14.9) vs 49.6(16.7); p=0.001] and increased gastrointestinal symptoms [GSRS 37.7(14.7) vs 29.0(12.8); p=0.001] compared with food secure CeD patients. Conclusions Food insecurity is common in patients with CeD and is associated with significantly worse adherence to treatment, symptom control, and quality of life. There is an important need for programs and societal measures to abolish food insecurity and ensure adequate access to treatment for patients with CeD. Funding Agencies TRIANGLE Summer Studentship

A69 EXPANDED ROLE OF THE DIETITIAN IN THE CLINICAL MANAGEMENT OF PATIENTS WITH CELIAC DISEASE

Abstract Background The only available treatment for Celiac Disease (CeD) is adhering to a strict gluten-free diet (GFD). However, a GFD has been associated with multiple nutrient imbalance and deficiencies, which are often under-recognized and remain untreated. Aims To identify the reasons for referral to a registered dietitian (RD) and RD-recommended dietary interventions for patients with CeD attending a specialised Adult Celiac Disease Clinic. Methods We conducted a retrospective chart review using nutrition assessment forms completed by the RD between November 2021 and May 2022. CeD diagnosis was performed through specific serology (anti-tissue transglutaminase IgA and anti-deamidated gliadin peptide IgG) and confirmed by duodenal biopsies demonstrating villous atrophy. We collected data on demographics, diagnosis date, nutritional status (BMI), micronutrients measured in serum, gastrointestinal (GI) symptoms, reason for consult, and the recommendations made by the RD. Data was collected in RedCap (v. 11.1, 2021, US) and expressed as both a proportion and Median (IQR). Results A total of 136 visits from 102 patients were included in the analysis. Of them, 77 were female (75.5%) with a mean age of 40.3 yrs (+/- 16.0). The median year of CeD diagnosis was 4 (IQR= 6) from 2002-2022. Patients reported various symptoms including bloating (50.9%), abdominal pain (34.3%), and constipation (23.5%). 56% of patients were overweight or obese (BMI ampersand:003E25), and 4.9% were undernourished (BMIampersand:003C18). The most common nutrient deficiencies were ferritin below 30 ng/mL (58.8%), zinc below 9.4 µmol/L (23.5%), and suboptimal levels of vitamin D (38.2%). The most common reasons for referral to the RD were to assess GFD adherence (44.1%), dietary management of GI symptoms (30.4%) and nutritional optimization (24.5%). We identified 18 different interventions recommended by the RD, the most common being how to prevent gluten cross-contamination (58.8%), tips for dining out (43.1%), GF diet education (32.4%), and increasing fibre intake (30.4%). The most common reasons for follow up visits (n=34) included dietary management of GI symptoms (60.9%) and GFD adherence (43.5%). Conclusions Patients with CeD face multiple nutritional challenges associated with following a GFD, and a number of GI symptoms. Although the GFD is the only available treatment, this review identifies the need for multiple individualized dietary interventions, which require and encourage the inclusion of a specialized RD to ensure personalized, effective care and support in the management of CeD.

Celiac disease symptom profiles and their relationship to gluten-free diet adherence, mental health, and quality of life

BackgroundA subgroup of adults with celiac disease experience persistent gastrointestinal and extraintestinal symptoms, which vary between individuals and the cause(s) for which are often unclear.MethodsThe present observational study sought to elucidate patterns of persistent symptoms and the relationship between those patterns and gluten-free diet adherence, psychiatric symptoms, and various aspects of quality of life (QOL) in an online sample of adults with celiac disease. U.S. adults with self-reported, biopsy-confirmed celiac disease (N = 523; Mage = 40.3 years; 88% women; 93.5% White) voluntarily completed questionnaires as part of the iCureCeliac® research network: (a) Celiac Symptoms Index (CSI) for physical symptoms and subjective health; (b) Celiac Dietary Adherence Test for gluten-free diet adherence; (c) PROMIS-29, SF-36, and Celiac Disease Quality of Life Survey for psychiatric symptoms and QOL. Symptom profiles were derived using latent profile analysis and profile differences were examined using auxiliary analyses.ResultsLatent profile analysis of CSI items determined a four-profile solution fit best. Profiles were characterized by: (1) little to no symptoms and excellent subjective health (37% of sample); (2) infrequent symptoms and good subjective health (33%); (3) occasional symptoms and fair to poor subjective health (24%); (4) frequent to constant symptoms and fair to poor subjective health (6%). Profiles 2 and 3 reported moderate overall symptomology though Profile 2 reported relatively greater extraintestinal symptoms and Profile 3 reported relatively greater gastrointestinal symptoms, physical pain, and worse subjective health. Profiles differed on anxiety and depression symptoms, limitations due to physical and emotional health, social functioning, and sleep, but not clinical characteristics, gluten-free diet adherence, or QOL. Despite Profile 3’s moderate symptom burden and low subjective health as reported on the CSI, Profile 3 reported the lowest psychiatric symptoms and highest quality of life on standardized measures.ConclusionsAdults with celiac disease reported variable patterns of persistent symptoms, symptom severity, and subjective health. Lack of profile differences in gluten-free diet adherence suggests that adjunctive dietary or medical assessment and intervention may be warranted. Lower persistent symptom burden did not necessarily translate to better mental health and QOL, suggesting that behavioral intervention may be helpful even for those with lower celiac symptom burden.

Clinical Data Do Not Reliably Predict Duodenal Histology at Follow-up in Celiac Disease: A 13 Center Correlative Study.

Validated nonbiopsy methods to assure duodenal mucosal healing in celiac disease are lacking, yet ongoing mucosal injury is associated with anemia, osteoporosis, and lymphoma. Most providers utilize clinical data as surrogates of mucosal status to avoid additional esophagogastroduodenoscopy. The reliability of such surrogates to predict mucosal recovery has been incompletely evaluated. The aim of this study was to rigorously assess patterns of histologic mucosal recovery at follow-up in celiac disease and to correlate findings with clinical data. Gastrointestinal pathologists from 13 centers evaluated initial and follow-up duodenal biopsies from 181 celiac disease patients. Marsh scores and intraepithelial lymphocytes (IELs)/100 enterocytes were assessed blindly. Histology at follow-up was correlated with symptoms, immunoglobulin A anti-tissue transglutaminase titers and gluten-free diet adherence. Fifty-six/181 (31%) patients had persistent villous blunting and 46/181 (25%) patients had just persistently elevated IELs at follow-up, with only 79/181 (44%) patients having complete histologic remission. IEL normalization (82/181; 45%) lagged villous recovery (125/181;69%). In a minority of patients, villous blunting was limited to proximal duodenal biopsies. No correlation was found between Marsh scores and symptoms, normalization of immunoglobulin A anti-tissue transglutaminase serology, or diet adherence. Children showed greater recovery of Marsh score (P<0.001) and IELs (P<0.01) than adults. Persistent mucosal injury is common in celiac disease, with discordant villous/IEL normalization. Pathologist awareness of expected findings in celiac disease follow-up biopsies, including their frequent lack of correlation with clinical data, is important for patient management, and has implications for eligibility criteria for therapeutics currently in development.

Not Quite Meeting the Mark: College Experiences for Patients With Celiac Disease.

Strict adherence to a gluten-free diet (GFD), the current treatment for celiac disease (CD), is socially challenging for adolescents, especially in the college setting. We conducted a survey of factors contributing to GFD adherence during college among patients meeting the ESPGHAN criteria for CD. One-hundred-one young adults (18 years and older) were contacted; 59 completed the survey, of which 47 were enrolled or had attended college. The survey was developed by the study team. Most patients were able to maintain strict adherence to the GFD, whereas at college and reported that GF food was available and consistent with expectations. Nearly all participants reported a lack of resources for students with CD. Strong family support helped, and school stress and lack of peer support impeded diet adherence. Although colleges may meet the basic needs of celiac students, the availability and quality of gluten-free options, and improved campus resources are needed.

Comparison of weekly gluten immunogenic peptide measurement and conventional tools to assess adherence to the gluten-free diet in celiac disease: An observational prospective study

BackgroundAdherence to the gluten-free diet (GFD) is critical to achieving symptom control and mucosal healing in celiac disease (CeD), but its assessment is difficult. ObjectivesWe sought to compare stool gluten immunogenic peptides (GIPs) measurements over a 4-wk period with conventional tools commonly used to monitor compliance with a GFD. MethodsConsecutive adult patients with CeD attending the Small Bowel Section of the Buenos Aires Gastroenterology Hospital were invited to this observational study and were instructed to collect stool samples on Fridays for 4 consecutive weeks. Weekly mean stool GIP concentration was measured was estimated. GIP results were compared with a self-assessment scale of adherence, specific CeD serology, the celiac symptom index, and the assessment by an expert dietitian. ResultsFifty-three CeD patients were enrolled and those with stool GIP ≥0.65 μg/g/wk (n = 13; 24.5%) had higher serum concentrations of IgA deamidated gliadin peptides (DGPs) antibodies [69 (29–109) compared with 14 (13–29); P = 0.0005] and IgA tissue transglutaminase [42 (14–200) compared with 10 (7–16); P = 0.02], higher proportion of cases with IgA DGP antibodies >20 AU/mL (84.6% compared with 33.3%; P = 0.002), and a higher self-estimated adherence score [5 (4–9) compared with 9 (7–10); P = 0.003]. GIP did not correlate with celiac symptom index scores (55.6% compared with 30.8%; P = 0.9). Expert dietitian assessment identified 69% [odds ratio (OR): 5.25; 95% CI: 1.1–27.2; P = 0.01] of nonadherent cases when high stool GIP. Logistic regression analysis determined that IgA DGP (adjusted OR: 1.1; 95% CI: 1.01–1.11; P = 0.02) and males (adjusted OR: 28.3; 95% CI: 1.1–722.6; P = 0.04) were independently associated with excessive gluten exposure. ConclusionsWeekly stool GIP identifies gluten exposure that is not always detected by commonly used GFD adherence assessment methods. The higher the concentration of stool GIP, the better the predictive value of serology and dietitian interviews. Stool GIP is a useful and practical test for GFD monitoring, particularly for risky gluten exposure in real-life scenarios.
