NCT01407640

  Purpose

Insulin allergy (IA) is still observed even with recombinant human insulin and insulin analogs.

Obviously, the usual attitude facing an allergy, i. e. exclusion of the allergen, poses problems in face of IA because insulin is often vital for the patient. IA is thus a complex situation in which a rigorous diagnostic procedure to identify the exact allergen is necessary to propose a therapeutic answer; the purpose of the study is 1/ to validate a diagnostic algorithm for patients presenting with possible allergy. 2/ to investigate immunogenetic profiles of patient with insulin allergy 3/ cellular mechanisms of IA.

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • Validation of cutaneous insulin tests [ Time Frame: after 36 months ] [ Designated as safety issue: Yes ]
    Response of cutaneous insulin tests in patients with IA (Insulin Allergy) at study completion.


Secondary Outcome Measures:
  • Immunogenetic of patients with IA (Insulin Allergy) [ Time Frame: after 36 months ] [ Designated as safety issue: Yes ]
    Immunogenetic of patients with IA (Insulin Allergy) at study completion Determination of insulin epitopes that are involved in IA at study completion Determination of isotypes of anti insulin antibodies and whether specific isotypes are associated with susceptibility / protection at study completion
