no nom\u00e9s confirma la prevalen\u00e7a dels autoanticossos en un nombre important de pacients amb pitjor pron\u00f2stic, sin\u00f3 que a m\u00e9s els correlacionen amb biomarcadors bioqu\u00edmics ja en \u00fas cl\u00ednic, com la disminuci\u00f3 de limf\u00f2cits o l’augment de la prote\u00efna C-reactiva, i subratllen el valor predictiu d’aquests anticossos contra interfer\u00f3<\/em>“. Aquests resultats suggereixen que la detecci\u00f3 d’autoanticossos contra l’interfer\u00f3 a l’arribada a l’hospital podria ser de gran utilitat per seleccionar aquells pacients amb m\u00e9s probabilitat de patir hiperimmunitat (tempesta de citocines) i acabar a l’UCI, i aix\u00ed, poder adaptar el tractament administrat a aquests pacients, per exemple, intensificant l’administraci\u00f3 d’interfer\u00f3 exogen.<\/p>\nPer la seva banda, el Dr. Troya<\/strong> indica que “en les dades recollides hem observat una correlaci\u00f3 entre la pres\u00e8ncia d’autoanticossos i un major risc de mort, per\u00f2, aquests s\u00f3n resultats en una cohort limitada de 47 pacients i l’ideal seria ampliar-los amb m\u00e9s pacients<\/em>“. “D’altra banda, no hem vist que el tractament exogen amb interfer\u00f3 hagi millorat el pron\u00f2stic dels pacients, aix\u00f2 pot ser degut que el grup estudiat constava de pacients amb la malaltia molt avan\u00e7ada. Proposem estudiar l’administraci\u00f3 primerenca d’aquesta citocina en pacients amb autoanticossos contra interfer\u00f3 en els primers estadis de la malaltia per determinar la seva efectivitat<\/em>“, comenta el Dr. Troya. L’estudi s’ha realitzat en col\u00b7laboraci\u00f3 amb el laboratori de Paul Bastard<\/strong> i Jean Laurent<\/strong> Casanova<\/strong> a Rockefeller University NYC\/Imagine Institute a Par\u00eds.<\/p>\nEls interferons s\u00f3n prote\u00efnes de senyalitzaci\u00f3 similars a les hormones que s\u00f3n essencials en la defensa contra les infeccions v\u00edriques. Aquest tipus resposta immune \u00e9s encara m\u00e9s important en la lluita contra el virus SARS-CoV-2, ja que el mateix virus t\u00e9 mecanismes per reduir la producci\u00f3 d’interfer\u00f3 per part de les c\u00e8l\u00b7lules del sistema immunitari. Per tant, en les persones amb anticossos contra aquesta citocina els efectes se sumarien i el virus passaria inadvertit per a les defenses de l’organisme.<\/p>\n
