The Aim of This Project is to Verify Whether a Depletion of B Cell Memory Subpopulation ("Marginal-zone-like") CD19 + IgD + CD27 + and CD19 + IgM + CD27 + is a Useful Indicator of Hyposplenism in Patients With Celiac Disease

Study Purpose

This project is expected to confirm the hypothesis that hyposplenism in patients with celiac disease is not conditioned by a selective memory deficiency of B lymphocytes. Other objectives of project are: - determination of gliadin 33-mer in faecal and urine as indicators patient´s adherence to gluten-free diet - determination of citrulline in plasma as an indicator of the overall functional capacity enterocytes

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.

Eligible Ages 18 Years and Over

Trial Details

Trial ID:

This trial id was obtained from, 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.

Additional Details

Ultrasound examination is focused to spleen size (spleen volumetry). Methodology of laboratory examinations is based on venous blood sampling for the determination of memory B-like marginal zone by flow cytometry; gliadin 33-mer (ELISA) determination in faecal and urine sample; blood plasma extraction for citrulline (high performance liquid chromatography, HPLC).

No Intervention: healthy blood donors

No intervention in this group.


Diagnostic Test: - venous blood sampling

Venous blood samples to determine memory B lymphocytes.

Procedure: - spleen volumetry

Ultrasound examination of spleen to scaled the size.
