Brief Summary:
Persons with coeliac disease treated with a gluten free diet will be asked to give blood for a new diagnostic blood test. In this test investigators will use multimerized HLA bound to different gliadin-peptides (tetramer) and with the help of a flow-cytometer identify (along with other relevant T-cell-markers) gluten specific T-cells. Investigators believe that these cells will be present in persons with coeliac disease regardless of gluten-intake. Investigators will compare their findings with two control groups; Persons on a gluten free diet where celiac disease is excluded (gluten sensitive group) and persons on a gluten containing diet (healthy control group). In the initial and main study investigators will look at HLA DQ2.5 individuals, which comprise >90% of all persons with coeliac disease.

Group/Cohort
Coeliac
Persons with coeliac disease on a gluten free diet where diagnosis is confirmed by duodenal biopsy.
Non coeliac gluten sensitive
Persons on a gluten free diet where coeliac disease is excluded by duodenal biopsy.
Healthy control group
Persons on a gluten containing diet without known coeliac disease.


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Ability of the tetramer test in differentiating persons with coeliac disease from controls by the use of tetramer staining for gluten specific T-cells and flowcytometry [ Time Frame: Upto 20 months ]

Biospecimen Retention:   Samples With DNA
A tetramerbased bloodtest which will bind and identify gluten specific T-cells by the use of a flow cytometer. 50 ml blood will be needed for this test, along with characterization of other blood values (eg. Hb, leukocytes, transferrin binding, B12, biobanking etc).
