Un equipo de investigadores canadienses y chinos ha logrado un gran avance en el trasplante de ri\u00f1ones al crear un ri\u00f1\u00f3n ‘universal’ compatible con todos los pacientes, independientemente del tipo de sangre que tengan. Este logro tiene un enorme potencial de reducir significativamente la espera para obtener \u00f3rganos de donantes y salvar m\u00e1s vidas,\u00a0indica<\/a>\u00a0un comunicado de la Universidad de Columbia Brit\u00e1nica, en Canad\u00e1, que ha participado en el ensayo cl\u00ednico.<\/p>\n

Actualmente, los \u00f3rganos de donantes solo pueden trasplantarse a personas con un tipo de sangre compatible. Esto se debe a que el sistema inmunitario de los receptores con diferentes tipos de sangre puede producir anticuerpos que atacan y destruyen el \u00f3rgano trasplantado. Hay diferentes tipos de ant\u00edgenos, como el A y el B. Las personas con el tipo de sangre O son donantes universales porque sus gl\u00f3bulos rojos carecen de los ant\u00edgenos A o B.<\/p>\n

El\u00a0equipo de cient\u00edficos pudo eliminar los ant\u00edgenos de tipo A de un ri\u00f1\u00f3n donado y hacer que el \u00f3rgano fuera universal para trasplantes. Para ello, utilizaron enzimas especializadas que eliminaron ant\u00edgenos de tipo A del \u00f3rgano para convertirlo en el tipo O. Luego,\u00a0lo trasplantaron a un paciente de 68 a\u00f1os con muerte cerebral en Chongqing, China (con el consentimiento de la familia),\u00a0informa<\/a>\u00a0Nature.<\/p>\n

Este pa\u00eds rompe r\u00e9cords en la eutanasia voluntaria: \u00bfqu\u00e9 hay detr\u00e1s y por qu\u00e9 genera pol\u00e9mica?<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<\/div>\n<\/div>\n

\u00abEs la primera vez que observamos este fen\u00f3meno en un modelo humano\u00bb<\/h3>\n

Durante dos d\u00edas, el ri\u00f1\u00f3n funcion\u00f3 sin signos de rechazo. Al tercer d\u00eda, reaparecieron algunos marcadores del tipo sangu\u00edneo, lo que provoc\u00f3 una reacci\u00f3n leve, pero el da\u00f1o fue mucho menos pronunciado que el de una incompatibilidad t\u00edpica. Despu\u00e9s de esto, los investigadores observaron signos de injerto del \u00f3rgano y, de esta manera, finalizaron con \u00e9xito el experimento.<\/p>\n

\u00abEsta es la primera vez que observamos este fen\u00f3meno en un modelo humano\u00bb,\u00a0se\u00f1al\u00f3 el bioqu\u00edmico Stephen Withers, uno de los responsables del estudio.\u00a0\u00abNos proporciona informaci\u00f3n invaluable sobre c\u00f3mo mejorar los resultados a largo plazo\u00bb, afirm\u00f3.<\/p>\n

Ahora los cient\u00edficos est\u00e1n a la espera de la aprobaci\u00f3n regulatoria para realizar ensayos cl\u00ednicos piloto en pacientes vivos. Unos resultados exitosos podr\u00edan abordar significativamente la escasez actual de \u00f3rganos de donantes, que sigue siendo un problema grave: los pacientes pueden esperar a\u00f1os para recibir su turno para recibir un \u00f3rgano compatible.<\/p>\n","protected":false},"excerpt":{"rendered":"
