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.

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.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

|Lymphocytic Enteritis (Disorder), Healthy Volunteers|
Hypothesis: The evaluation of the lymphocyte subpopulations of the subjects without digestive symptoms and normal upper digestive tract mucosa will allow to have a healthy control group with which to compare the cellular patterns of different chronic inflammatory diseases.
Other: Healthy group
A group of healthy, strictly asymptomatic individuals of both sexes and different age groups.
Other: - Endoscopy
A dyspepsia test will be performed to avoid selection bias. In subjects strictly asymptomatic, a blood analysis will be proposed. Subjects who present strictly normal laboratory tests (including celiac serology and negative H Pylori tests) and no genetic risk of celiac disease will be invited to perform an upper gastrointestinal endoscopy. During gastroscopy, samples of normal mucosa will be taken for histological and lymphocyte subpopulations analysis. The percentage of lymphocyte subpopulations will be assessed by flow cytometry. To compare whether there are differences between the lymphocyte subpopulations related to the age and sex of the healthy individuals, a student's t test, ANOVA or the corresponding non-parametric test will be used. The values will be expressed according to: mean +/- 2DS or median and interquartile range.
