Impact of Gluten Contamination in Celiac Patients Clinically Responsive and Unresponsive to the Gluten-free Diet

Study Purpose

The primary aim of the study is to detect the presence of gluten immunogenic peptides (GIP) in urine samples from celiac patients on a gluten-free diet clinically responsive and non-responsive to dietary treatment and from suspected celiac patients already on a gluten-free diet.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05066191
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Once a year, celiac patients perform a clinical (gastroenterological visit) and blood chemistry (blood tests) check. At the Center for the Prevention and Diagnosis of Celiac Disease, about 1400 check-ups of celiac patients are carried out per year. During this annual control visit, consecutive patients afferent to the center and suffering from celiac disease who have been treated for more than 6 months, clinically "responsive" and "non-responsive" to the gluten free diet (GFD), will be invited to participate in the proposed study. Those who participate will be given the symptom questionnaires (VAS), the food questionnaire in order to evaluate the relevance of the symptoms reported and the type of diet followed by the patient and the adherence test to the gluten-free diet (CDAT). Urine samples will be collected to test the presence of GIP (gluten immunogenic peptides) and for patients whose samples test positive, will be asked for a stool sample to detect GIP. Subjects with suspected celiac disease but already on a gluten-free diet will undergo a challenge, or the reintroduction of gluten in incremental steps of three weeks (routinely performed as per the instructions of the Italian Health Care System).
