- Brief Summary
The investigators propose to plan for a multi-center randomized controlled trial (M-RCT) to test the effectiveness of novel gluten detection technologies as an adjunct to telemedicine to manage celiac disease in newly diagnosed adults. If successful, the proposed intervention will improve mucosal recovery, promote a shift in current practice of celiac disease management toward long-term monitoring, and represent a significant step toward reducing the severe physical and psychological consequences of celiac disease.
- Detailed Description
The proposed project addresses the need for a rigorous trial to test the effectiveness of novel gluten detection technologies as an adjunct to telemedicine to manage celiac disease in adults. Celiac disease affects about 1% of the United States (U.S.) population and seroprevalence has increased up to 5-fold in the U.S. since the 1950's, with diagnosis rates continuing to rise. Morbidity can be severe and includes anemia, infertility, osteoporosis, and malignancies, which can increase all-cause mortality. The only proven therapy is a strict gluten-free diet, the management of which can be extremely challenging and has been linked to diminished quality of life, including anxiety, depression, and fatigue. Despite the recommendation to see a dietitian regularly, many with celiac disease do not see one at all or have only a single session immediately post-diagnosis. The COVID-19 pandemic has catalyzed the rapid adoption of telemedicine in gastroenterology and can facilitate communication between patient and dietitian by eliminating the need to arrange face-to-face meetings at celiac disease centers, which may be at great distance. Self-monitoring with new technologies for gluten detection in urine (e.g., gluten immunogenic peptide kits) can facilitate greater individual awareness of gluten exposures, are commercially available to the public, and have been shown to be valid and reliable. Physicians and dietitians are being asked if this technology should be used, and our preliminary studies have demonstrated acceptability and feasibility, but their impact on clinical outcomes such as mucosal recovery and symptoms has not been established. This U01 proposal is for a multi-center (New York, Massachusetts, Illinois, Tennessee) randomized controlled trial (M-RCT) to assess the effectiveness and document costs of gluten detection technologies as an adjunct to telemedicine on behavioral and clinical outcomes among newly diagnosed patients with celiac disease. Participants will be randomized to receive either 1) standard of care (i.e. a one-time in-person dietitian session plus telemedicine dietitian follow-up; or 2) standard of care + gluten detection technology. This would be the first large-scale clinical trial to test the effect of self-monitoring using gluten detection technology in the management of celiac disease. The primary outcome will be mucosal recovery 12-months post-randomization. Secondary outcomes include change in gastrointestinal symptoms, diet adherence, quality of life (including anxiety and depression), eating behaviors, intraepithelial lymphocyte counts on histology, and celiac disease serology, all assessed at baseline and again at 12-months post-randomization. If the primary endpoint of this proposed U01 is met, the intervention will improve mucosal recovery, promote a shift in current practice of celiac disease management toward long-term monitoring, and represent a significant step toward reducing the severe physical and psychological consequences of celiac disease.

- Primary Outcome Measures
Name Time Method Small Intestinal Healing 12 months This will be measured with a measure in villus height to crypt depth ratio on small intestinal biopsy.
- Secondary Outcome Measures
Name Time Method Score on the Celiac Dietary Adherence Test (CDAT) 12 months Gastrointestinal symptoms will be measured using a validated instrument, the CDAT, which is used to assess adherence to a gluten-free diet (GFD). The questionnaire consists of 7 items on a 5-point Likert scale, and the sum of the numeric values assigned to the answers provides a score ranging from 7 to 35 points, with a lower score indicating excellent GFD adherence (better outcome).
Score on the Celiac Disease Symptom Diary (CDSD) 12 months Celiac disease symptoms will be measured with a validated 5-item score measuring intestinal and extra-intestinal symptoms. Each question is scored to calculate a composite score, which can range from 0 (min) to 20 (max), with 0 indicating least severe (better outcome) and 20 indicating most severe.
Score on the Celiac-Disease specific Quality of Life (CDQOL) 12 months CD-QOL is a self-administered questionnaire, which has 20 items across four clinically relevant subscales that are to be answered using a Likert scale. The overall score is expressed on a scale of 0-100, with a higher score suggesting a better quality of life and better outcome (a poor score is less than or equal to a score of 40, and a good overall score is greater than or equal to a score of 60).
Score on PROMIS 29+2 12 months The The Patient-Reported Outcomes Measurement Information System (PROMIS)-29+2 Profile v2.1 (PROPr) is used to calculate a preference score. Preference-based scores provide an overall summary of health-related quality of life on a common metric. Preference-based scores summarize multiple domains on a metric ranging from 0 (as bad as dead) to 1 (perfect or ideal health). The profile includes all items in the PROMIS-29 plus two Cognitive Function Abilities items. Scores are calculated using a table to translate the total raw score into a T-score for each participant. The T-score rescales the raw score into a standardized T-score with a mean of 50 and a standard deviation (SD) of 10. Scores can range from 31 (min) to 155 (max), and a higher score indicates a better outcome.
Score on the State-Trait Anxiety Inventory (STAI) 12 months Anxiety will be measured using the STAI, which is a psychological inventory consisting of 40 self-report items on a 4-point Likert scale. The STAI measures two types of anxiety - state anxiety and trait anxiety. Scores range from 20 to 80, with higher scores correlating with greater anxiety (worse outcome).
Score on the Center for Epidemiologic Studies Depression Scale for adults (CESD-R) 12 months Depression will be measured using a 20-item validated survey instrument, the Center for Epidemiologic Studies Depression Scale (CESD-R). This scale is a self-report measure of depression. The questions measure 8 different subscales, including: sadness (dysphoria), loss of interest (anhedonia), appetite, sleep, thinking/concentration, guilt (worthlessness), tired (fatigue), movement (agitation), suicidal ideation. The response values for each question range from 0 (Not at all or less than one day) to 4 (Nearly every day for 2 weeks) The total score is calculated by finding the sum of 20 items. Scores range from 0-60 with a higher score indicating a worse outcome. A score equal to or above 16 indicates a person at risk for clinical depression.
Score on the CD-FAB 12 months Eating patterns and behaviors will be measured with the Celiac Disease Food Attitudes and Behaviors (CD-FAB). The CD-FAB is an 11-item self-reported, validated tool that investigates the eating attitudes and behaviors resulting from beliefs concerning cross-contamination, trust, risk-taking, and food safety. Items are based on a 7-point Likert scale and total scores range from 11 to 77, with a higher score suggesting more maladaptive eating attitudes and behaviors (worse outcome).
Intraepithelial Lymphocyte Count (ILC) 12 months Intraepithelial lymphocyte count will be assessed using standardized procedures (duodenal biopsy). Using a length of surface epithelium of an entire villus and/or the villous tip in formalin fixed, paraffin embedded, Hematoxylin and Eosin-stained biopsies under the light microscope. The results are expressed as lymphocytes per 100 epithelial cells.
Tissue Transglutaminase IgA (TTG-IgA) Level 12 months Serum Tissue Transglutaminase immunoglobulin A (IgA) will be measured using standardized immunoassays.
DGP IgA/IgG Level 12 months Serum Deamidated gliadin peptide (DGP) IgA/IgG will be measured using standardized immunoassays.
