Clinical Trial Summary

Sublingual immunotherapy is developing in the treatment of aeroallergens allergy. The hypothesis is that such process may be applied to food allergy, more precisely to milk. A previous series of 8 patients indicates the likely effectiveness of this technique (Allergy, 2006).


Clinical Trial Description

National study of current practice, multicentric, randomized, open All oral provocation tests will be randomized, double blind Study treatment. For oral provocation test, placebo with NeocatePasteurized half skimmed milk (available in standard outlets) from 0.1 to 0.8 mL/day Tests At M0 :1) Clinical examination 2) Biological test (blood sample 16.5 mL) : WBC, ferritin, total IgE, specific IgE, cow milk, ALPHALACTALBUMIN , casein, BETALACTOGLOBULIN and goat milk using RASTSpecific secretory IgA by ESPCI (frozen saliva)Biologic collection- Specific immunoglobulins against cow' milk, ALPHALACTALBUMIN, casein, BETALACTOGLOBULIN, quantification of IgM, sub classes of IgG and IgA by ESPCI (frozen serum).

Analysis of minor allergens by immunoblot 2 D, ESPCI (frozen serum)3) prick tests 4) 1 or 2 oral provocation test (TPO) double blind, during 2 days At M3 : clinical examination, side effects during the 3 preceding months At M6 :1) Clinical examination 2) Biological test (blood sample 16.5 mL) : WBC, ferritin, total IgE, specific IgE, cow milk, ALPHALACTALBUMIN, casein, BETALACTOGLOBULIN and goat milk using RAST Specific secretory IgA by ESPCI (frozen saliva)Biologic collection Specific immunoglobulins against cow' milk, ALPHALACTALBUMIN, casein, BETALACTOGLOBULIN, quantification of IgM, sub classes of IgG and IgA by ESPCI (frozen serum).
