En ce qui concerne l’influence des traitements m\u00e9dicamenteux (anti-d\u00e9mangeaisons), il convient de distinguer les tests d’allergie intradermiques (IDAT) et les tests s\u00e9rologiques d’allergie (SAT).<\/p>\n

On peut logiquement s’attendre \u00e0 ce qu’une r\u00e9action allergique cutan\u00e9e, c’est-\u00e0-dire un \u00e9ryth\u00e8me et des d\u00e9mangeaisons, soit supprim\u00e9e par les m\u00e9dicaments actuellement disponibles, en particulier lorsque le m\u00e9canisme \u00e0 l’origine de cette r\u00e9action est directement bloqu\u00e9. Th\u00e9oriquement, en revanche, il y a peu de raisons de penser que les anticorps IgE disparaissent du sang \u00e0 relativement court terme ou que leur production cesse sous l’influence de ces produits, car aucun d’entre eux n’agit directement sur les IgE.<\/p>\n

C’est \u00e9galement ce qu’ont montr\u00e9 toutes les \u00e9tudes men\u00e9es jusqu’\u00e0 pr\u00e9sent sur ce sujet, \u00e9tant entendu qu’il ne s’agit que d’un petit nombre d’\u00e9tudes, que leur port\u00e9e est limit\u00e9e et que certaines interactions n’ont pas encore \u00e9t\u00e9 \u00e9tudi\u00e9es du tout. D’autre part, le consensus au sein de la m\u00e9decine humaine, qui dispose d’un corpus de connaissances plus \u00e9tendu, est le m\u00eame: l’IDAT est souvent affect\u00e9e, le SAT pas ou beaucoup moins.<\/strong><\/p>\n<\/div>

L’ac\u00e9promazine et les d\u00e9riv\u00e9s de la morphine ne sont pas recommand\u00e9s en raison de leur effet de lib\u00e9ration d’histamine. Les progestatifs, les agonistes \u00df2-adr\u00e9nergiques, les bronchodilatateurs et les antid\u00e9presseurs tricycliques sont \u00e9galement mentionn\u00e9s dans la liste des m\u00e9dicaments \u00e0 \u00e9viter pendant l’IDT, mais ils reposent sur une extrapolation de la m\u00e9decine humaine ou sur des bases th\u00e9oriques et non-\u00e9tudi\u00e9s chez les chiens.<\/p>\n

Conclusion SAT<\/h2>
Les quelques \u00e9tudes men\u00e9es jusqu'\u00e0 pr\u00e9sent n'ont pas permis de d\u00e9montrer l'interf\u00e9rence des m\u00e9dicaments sur les tests d'allergie au s\u00e9rum (SAT). Le tableau ci-dessus indique les temps d'attente recommand\u00e9s pour certaines familles de produits cl\u00e9s. Cependant, toutes les variantes possibles du produit, du r\u00e9gime posologique et de la dur\u00e9e du traitement n'ont pas \u00e9t\u00e9 \u00e9tudi\u00e9es. En particulier avec les glucocortico\u00efdes, il appartient au clinicien de juger, en fonction de la puissance, de la dur\u00e9e et de la dose, s'il est pr\u00e9f\u00e9rable d'attendre avec le SAT ou non.<\/div>
