Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
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.
|Eligible Ages||18 Years - 75 Years|
- - patients suffering from NCGS/NCWS on Gluten-Free Diet (GFD).
- - celiac patients or those suffering from IgE-mediated gluten/wheat allergy.
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.
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.

|Non-celiac Gluten/Wheat Sensitivity|
Non-celiac gluten/wheat sensitivity (NCGS/NCWS) is a syndrome characterized by both intestinal (irritable bowel syndrome [IBS]-like presentation) and extraintestinal symptoms (headache, migraine, "foggy mind", depression, anxiety, fibromyalgia, joint and muscle pain, leg or arm numbness, eczema or skin rash), which occur after the ingestion of gluten/wheat in subjects in which celiac disease (CD) and wheat allergy diagnosis has been previously excluded. Recent data suggest that NCGS affect up to 3-6% of the general population, a higher prevalence than that reported for CD. NCGS/NCWS symptoms generally occur after the ingestion of gluten/wheat, disappear within a few days of a gluten-free diet (GFD) and quickly reappear when gluten/wheat is reintroduced. GDF is very difficult and onerous from a social (presence of gluten in many industrial food products and "contamination", both domestic and extra-domestic), psychological (e.g. for adolescents, exclusion from the "peer group", with difficulty in accepting the diagnosis) and economic point of view. A new assay, recently available on the Italian market, allows to ascertain the presence of immunogenic peptides of gluten (gluten immunogenic peptides, GIP) in the urine and stool. The test might allow to ascertain if the NCGS/NCWS patients, on GFD, eat even accidentally gluten. Of the 2 available assays, the urinary one allows the patient himself to test the presence of GIP in relation to symptoms/signs appearing and/or social activities (e.g. meal in a restaurant). The other one involves collecting a stool sample and allows to identify the gluten taken in the previous week, but it requires a laboratory, specifically equipped. To date, there are no observational studies that indicate the performance of the test in patients with NCGS/NCWS. The aims of the present study are: 1) to test, in patients with NCGS/NCWS on GFD, the adherence to the elimination diet; 2) to evaluate the correlation between the symptoms' reappearance and the presence of GIP in the urine.
Other: Patients affected with Non-celiac Gluten/Wheat Sensitivity
The researchers will deliver to each patient 10 kits for the analysis of the GIP and they will ask them to use them two times per week, for 5 weeks. Furthermore, the patients will test urine GIP in the event of symptoms/signs that they attribute to the accidental intake of gluten, within the same 5 weeks. Both gastrointestinal and extra-intestinal symptoms which the patients will attribute to the accidental intake of gluten, will be considered.
Other: - Urinary test
Detection of the presence of gluten immunogenic peptides (GIP) in the urine of NCGS/NCWS patients, evaluated two times per week, for 5 weeks, and in the event of symptoms/signs that the patients attribute to the accidental intake of gluten, within the same 5 weeks.
