Ainsi, chez certains, les oreilles se mettent \u00e0 d\u00e9manger et le palais \u00e0 gratter. A tel point que seuls l\u2019introduction de l\u2019auriculaire dans le premier cas et le passage de la langue dans le second permettent de se soulager.<\/p>\n<p><b>Mais alors, \u00e0 quoi sont dues ces r\u00e9actions ?<\/b><\/p>\n<p>Il faut se rappeler que chez un sujet allergique, lors de la premi\u00e8re exposition \u00e0 un allerg\u00e8ne, les globules blancs fabriquent des anticorps, en particulier l\u2019immunoglobuline E (IgE), qui pr\u00e9parent le syst\u00e8me immunitaire pour la prochaine rencontre. Durant cette premi\u00e8re exposition, les IgE se fixent aux mastocytes, des cellules immunitaires.<\/p>\n<p><b>\u00ab Mais lors de la deuxi\u00e8me rencontre avec un allerg\u00e8ne, la fixation des IgE sur les mastocytes provoque la d\u00e9granulation de ces derniers et ainsi la lib\u00e9ration de diff\u00e9rentes substances, comme l\u2019histamine, qui ont des propri\u00e9t\u00e9s inflammatoires \u00bb,<\/b><\/p>\n<p>note le Pr Fr\u00e9d\u00e9ric B\u00e9rard, chef de service d\u2019allergologie et d\u2019immunologie clinique \u00e0 l\u2019H\u00f4pital Lyon Sud. \u00ab Ce qui provoque les r\u00e9actions allergiques \u00bb, souligne-t-il.<\/p>\n<p>Or, les mastocytes sont particuli\u00e8rement pr\u00e9sents au niveau de la peau, de la bouche et du nez. Au contact des muqueuses, la lib\u00e9ration d\u2019histamine va provoquer une sensation de d\u00e9mangeaison, par exemple au niveau du palais mais aussi au fond de la gorge. Ce qui r\u00e9sonne vers les oreilles qui vont, \u00e0 leur tour, se mettre \u00e0 gratter.<\/p>\n<p>Le Pr B\u00e9rard admet que se chatouiller fr\u00e9n\u00e9tiquement l\u2019oreille avec le doigt ou le palais avec la langue peut soulager. Mais cela n\u2019a rien d\u2019esth\u00e9tique et encore moins de durable. \u00ab Les antihistaminiques seront vos meilleurs alli\u00e9s \u00bb, explique-t-il. \u00ab Ils sont tr\u00e8s bien tol\u00e9r\u00e9s. Les cortico\u00efdes locaux peuvent aussi vous aider. Enfin, n\u2019h\u00e9sitez pas \u00e0 consulter un allergologue. Ensemble, vous pourrez cibler les allerg\u00e8nes incrimin\u00e9s et envisager une d\u00e9sensibilisation \u00bb, ajoute-t-il.<\/p>\n<p><strong>Pour plus d&rsquo;informations et d&rsquo;analyses sur la <a href=\"https:\/\/www.africa-press.net\/cameroun\">Cameroun<\/a>, suivez <a href=\"https:\/\/www.africa-press.net\/\">Africa-Press<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Cameroun.
