Les proves acumulades indiquen que els embarassos despr\u00e9s de la transfer\u00e8ncia d’embrions congelats en cicles artificials s’associen a un major risc de preecl\u00e0mpsia. El Doppler de l’art\u00e8ria uterina, juntament amb els factors materns i els biomarcadores s\u00e8rics, \u00e9s un biomarcador crucial per al cribratge de la preecl\u00e0mpsia en el primer trimestre, que ajuda a identificar a les pacients \u00abd\u2019alt risc\u00bb. Les directrius recomanen encaridament administrar aspirina (150 mg\/dia) a aquestes dones, a causa de les s\u00f2lides proves que demostren una reducci\u00f3 del 62% en la incid\u00e8ncia de preecl\u00e0mpsia.<\/p>

No obstant aix\u00f2, i malgrat que estudis previs suggereixen un menor \u00edndex de pulsatilitat de l’art\u00e8ria uterina despr\u00e9s de la transfer\u00e8ncia d’embrions congelats, cap estudi previ ha explorat l’impacte del tipus de preparaci\u00f3 endometrial en el Doppler de l’art\u00e8ria uterina ni la seva influ\u00e8ncia en l’estimaci\u00f3 del risc de preecl\u00e0mpsia en el primer trimestre. Per aquest motiu, un grup d’investigadors del Servei de Medicina de la Reproducci\u00f3 de Dexeus Dona va decidir realitzar un estudi retrospectiu per avaluar-lo. <\/p>

L\u2019estudi, liderat per la primera autora del qual \u00e9s Valeria Donno<\/a>, ginec\u00f2loga especialitzada en reproducci\u00f3 assistida de Dexeus Dona<\/strong>, va incloure un total de 27.289 embarassos \u00fanics (concebuts de manera natural o despr\u00e9s de tractament de reproducci\u00f3 assistida) que es van sotmetre al cribratge ecogr\u00e0fic del primer trimestre a l\u2019Hospital Universitari entre gener de 2010 i maig de 2023. L\u2019objectiu de l\u2019estudi era valorar si existeix una associaci\u00f3 entre l\u2019\u00edndex de pulsatilitat de l\u2019art\u00e8ria uterina i el mode de concepci\u00f3, tenint en compte en l\u2019an\u00e0lisi multivariada factors de confusi\u00f3 (edat, pes, tabaquisme i donaci\u00f3 d\u2019ov\u00f2cits). <\/p>

Els resultats van demostrar que els embarassos despr\u00e9s de la transfer\u00e8ncia artificial d’embrions congelats presenten un \u00edndex de pulsatilitat de l’art\u00e8ria uterina significativament menor en el primer trimestre en comparaci\u00f3 amb els altres modes de concepci\u00f3. A m\u00e9s, el percentatge de pacients amb alt risc de preecl\u00e0mpsia en el cribratge del primer trimestre va ser significativament m\u00e9s baix en el grup de cicle artificial en comparaci\u00f3 amb els altres grups. Aix\u00f2 es va traduir en un menor nombre de pacients que van rebre aspirina profil\u00e0ctica. Els autors conclouen que l’algorisme de risc de preecl\u00e0mpsia en el primer trimestre podria veure’s influ\u00eft per aquesta variaci\u00f3 en l’art\u00e8ria uterina. A la llum d’aquestes troballes, \u00e9s fonamental avaluar la possibilitat d’ajustar aquest algorisme, incorporant factors de correcci\u00f3 per obtenir un c\u00e0lcul de risc m\u00e9s prec\u00eds i evitar que no s’apliqui tractament a pacients que podrien haver-se beneficiat de l’aspirina profil\u00e0ctica. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
