Afectant al voltant del 2% de la poblaci\u00f3, les malalties reum\u00e0tiques autoimmunes poden tenir s\u00edmptomes greus, com articulacions doloroses i inflamades, febre, erupcions cut\u00e0nies, fatiga i sensibilitat al sol, i els pacients necessiten revisions regulars. El diagn\u00f2stic pot demorar-se diversos anys des de l’aparici\u00f3 dels s\u00edmptomes, massa temps per evitar resultats negatius. A m\u00e9s, hi ha grans variacions entre els pacients en termes de gravetat, pron\u00f2stic i resposta al tractament, el que fa que la ter\u00e0pia sigui un proc\u00e9s de prova i error.<\/p>\n
\u00a0<\/p>\n
La majoria dels pacients reben esteroides, per\u00f2 aquests s’associen amb nombrosos efectes secundaris, com una major susceptibilitat a les infeccions, osteoporosi, augment r\u00e0pid de pes i malaltia cardiovascular. Tot i que s’estan desenvolupant tractaments prometedors, la classificaci\u00f3 per separat de la malaltia significa que els tractaments per a una malaltia no poden emprar-se per tractar-ne d’altres que puguin tenir una base molecular similar.<\/p>\n
\u00a0<\/p>\n
Els investigadors de la UE i el projecte PRECISESADS, finan\u00e7at per la ind\u00fastria i en qu\u00e8 participa el Dr. Esteban Ballestar com a investigador principal,\u00a0estan recopilant dades sobre les causes moleculars de diverses malalties reum\u00e0tiques autoimmunes i els s\u00edmptomes cl\u00ednics de diferents pacients per facilitar el subministrament de medicaments de precisi\u00f3 basats en un diagn\u00f2stic m\u00e9s primerenc i m\u00e9s prec\u00eds.<\/p>\n

Prescriure un tractament efica\u00e7 poc despr\u00e9s del diagn\u00f2stic i evitar m\u00e8todes costosos, inefica\u00e7os i fins i tot contraproduents t\u00e9 enormes beneficis, sobretot per als pacients. Les malalties reum\u00e0tiques autoimmunes, si se’ls permet progressar, solen causar danys irreversibles en les articulacions o \u00f2rgans principals.<\/p>\n

“Les mostres de sang de m\u00e9s de 3 000 pacients de tot Europa amb diferents malalties autoimmunes s’han sotm\u00e8s a\u00a0 an\u00e0lisis\u00a0sense precedents en el camp de la recerca en reumatologia”, explica el coordinador del projecte John Ioannou, d’UCB Biopharma a B\u00e8lgica. “Les dades sobre genoma, transcriptoma, proteoma, metiloma i altres par\u00e0metres biol\u00f2gics s’han analitzat amb la identificaci\u00f3 de nous grups de signatures moleculars, que podrien formar la base per a una nova classificaci\u00f3 d’aquestes malalties i aplanar el cam\u00ed cap a una ter\u00e0pia m\u00e9s personalitzada” .<\/p>\n
\u00a0<\/p>\n
Tractament personalitzat<\/strong><\/p>\n En analitzar les dades dels pacients utilitzant tecnologies d’avantguarda, els investigadors de PRECISESADS estan definint grups de persones en qu\u00e8 es produeixen interaccions moleculars similars. El projecte, despr\u00e9s d’identificar les caracter\u00edstiques de grups espec\u00edfics de malalties, recolzar\u00e1\u00a0els assaigs cl\u00ednics a l’hora de\u00a0determinar\u00a0quins pacients respondran a quins medicaments.<\/p>\n \u00a0<\/p>\n Els conjunts de dades generades per PRECISESADS permetran que la ind\u00fastria farmac\u00e8utica d’Europa comparteixi les troballes relacionades amb les malalties reum\u00e0tiques autoimmunes en una escala sense precedents. D’aquesta manera, proporcionaran una base perqu\u00e8 les institucions comercials i acad\u00e8miques examinin i validin nombroses hip\u00f2tesis sobre la classificaci\u00f3 de malalties i els biomarcadors.<\/p>\n \u00a0<\/p>\n Aix\u00f2 permetr\u00e0 superar el problema de la classificaci\u00f3 inadequada i identificar objectius com mol\u00e8cules o interaccions moleculars amb major probabilitat de ser susceptibles de tractament.<\/p>\n \u00a0<\/p>\n “Aquestes malalties tendeixen a superposar cl\u00ednicament i aix\u00f2 fa que sigui dif\u00edcil per a la ind\u00fastria farmac\u00e8utica trobar medicaments que realment benefici\u00efn els pacients”, diu Marta Alarc\u00f3n-Riquelme, cap de gen\u00f2mica m\u00e8dica del Centre de Gen\u00f2mica i Recerca Oncol\u00f2gica de la Universitat de Granada, entitat coordinadora del projecte. “Reclassificarem\u00a0als pacients en nous grups que podrien respondre molt millor a certs medicaments disponibles al mercat”.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n Un gran pas<\/strong><\/p>\n “PRECISESADS destaca l’enorme potencial que es pot desbloquejar a trav\u00e9s d’una col\u00b7laboraci\u00f3 funcional entre les grans companyies farmac\u00e8utiques, les PIME i el m\u00f3n acad\u00e8mic”, diu John Ioannou. “\u00c9s molt important arribar a temps amb el millor tractament per a tots els pacients. Ens queda una mica lluny, per\u00f2 aquest estudi proporciona un gran pas cap a l’assoliment d’aquest ambici\u00f3s objectiu”.<\/p>\n \u00a0<\/p>\n Dues confer\u00e8ncies amb experts internacionals en investigaci\u00f3 gen\u00f2mica translacional tamb\u00e9 han contribu\u00eft brindant oportunitats de capacitaci\u00f3 per a membres del consorci i passants, per aix\u00ed nodrir la propera generaci\u00f3 d’investigadors.<\/p>\n \u00a0<\/p>\n El projecte va ser finan\u00e7at per la Iniciativa Comuna per Medicaments Innovadors, una associaci\u00f3 p\u00fablic-privada entre la UE i la ind\u00fastria farmac\u00e8utica europea.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n Detalls del projecte<\/strong><\/p>\n \u00a0<\/p>\n Les malalties reum\u00e0tiques autoimmunes com l’artritis reumatoide, el lupus i l’esclerod\u00e8rmia s\u00f3n debilitants i, de vegades, amenacen la vida. Un projecte finan\u00e7at per la ind\u00fastria i la UE apunta a millorar el tractament en fer que les ter\u00e0pies adequades arribin als pacients correctes r\u00e0pidament.<\/p>\n","protected":false},"author":6,"featured_media":10532,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[332,376],"tags":[],"class_list":["post-7555","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cancer","category-epigenetica-del-cancer"],"publishpress_future_action":{"enabled":false,"date":"2024-11-29 03:25:15","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category"},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/posts\/7555","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/comments?post=7555"}],"version-history":[{"count":0,"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/posts\/7555\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/media\/10532"}],"wp:attachment":[{"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/media?parent=7555"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/categories?post=7555"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/idibell.cat\/wp-json\/wp\/v2\/tags?post=7555"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
