Study Summary

This study aims to build up a clinico-biological bank of samples from patients suspected of or suffering from allergic diseases (including asthma) or mast cell diseases in order to support future research in the field of allergic diseases. The biobank will help to identify new prognostic, diagnostic and/or predictive biomarkers.

Eligibility Criteria

Inclusion

Inclusion Criteria:

patients with a positive prick test or specific IgE regardless of the allergen

patients with systemic or cutaneous mastocytosis according to the internationalclassification8
patients with mast cell activation syndrome according to the internationalclassification8
patients with familial hyper-alpha tryptasemia on the presence of variation in thenumber of copies of the alpha allele of the TPSAB1 gene

Study Description

This is a prospective monocentric collection of biological samples combined with clinical and paraclinical data from patients suffering from allergic diseases, asthma or mast cell disorders. The aim of this collection is to collect biological samples and clinical data to be used for various exploratory, diagnostic and/or prospective and/or predictive studies.

The samples and data will be pseudonymised, i.e. identified by the first letter of the patient's surname and first name and by a number allocated in chronological order of patient inclusion, and will be stored in a bank. The samples and data making up this clinico-biological bank will be used for subsequent exploratory work used as a priority to answer questions from the Toulouse University Hospital teams in the field of allergic diseases, asthma and/or mast cell disorders, in accordance with the information given to the patient. They may also be transferred to specialised research teams as part of national or international collaborations, or sold to academic or industrial partners. These transfers as part of collaborations or assignments will be legally governed by contracts guaranteeing compliance with the RGPD, where applicable, and the use of these samples in accordance with current legislation and the information provided to patients.
