POR PRIMERA VEZ FUE CURADO UN HOMBRE QUE TENÍA VIH

5528_1.jpg

Al paciente, que era portador hace más de una década, le detectaron leucemia y tuvo que someterse a un trasplante de células madres. El destino quiso que el donante tenga resistencia genética al virus y se curó de ambas enfermedades. Un trasplante de células madres, a través de un donante de médula espinal, realizado el año 2007 hizo posible que el estadounidense Timothy Ray Brown (44) se convirtiera en el primer hombre en ser curado de VIH. Así lo han anunciado en la revista médica “Blood” los médicos alemanes de la clínica Charite de Berlín.

 

Brown, a quien se le conoce como el ‘Paciente de Berlín’, recibió el trasplante como parte de un tratamiento contra la leucemia que le sobrevino tres años atrás. Según “The Huffington Post”, sus médicos indicaron que los resultados sugieren “que la cura para la infección del VIH se ha logrado”.

El donante del ciudadano estadounidense tenía resistencia genética al virus y eso fue lo que determinó la cura de Brown, quien tuvo que someterse al trasplante luego de que los médicos decidieran que no podía continuar con sesiones de quimioterapia para combatir la leucemia que padecía.

El trasplante acabó tanto con la leucemia como con el VIH.

“IMPRACTICABLE”

Consultado al respecto por la cadena Fox, Anthony Fauci, director de los Institutos Nacionales de Alergias y Enfermedades Infecciosas de EE.UU. -que ha estudiado el VIH/sida durante casi 30 años-, dijo que aunque esta es una prueba interesante, es “absolutamente impracticable”.

“Ya es bastante difícil conseguir un donante compatible para un trasplante como este”, indicó Fauci citado dijo FoxNews.com, “Pero también hay que encontrar un donante compatible que tiene este defecto genético que se encuentra solamente en un 1% de la población caucásica y en el 0% de la población negra. Esto es muy raro”, ase

Añadió que aunque Timothy Ray está “funcionalmente curado”, esto no es algo que se pueda hacer con todas las personas infectadas con el VIH.

MÁS OPINIONES

Por su parte, el doctor Thomas Quinn, director del Centro Johns Hopkins para la Salud Global -quien está familiarizado con el “Paciente de Berlín”- dijo estar de acuerdo con los investigadores que calificaron el caso como el primer hombre curado del VIH.

“Brown ha estado sin tratamiento (contra el VIH) durante tres años y parece estar libre del virus. Con esto se da esperanza a las millones de personas infectadas de que existe una opción viable para su curación en el futuro”, afirmó.

Sin embargo, Quinn advirtió que se trataba de un caso raro y un trasplante de esta naturaleza no es la panacea para otros pacientes con VIH. “Es un procedimiento casi fatal que tuvo que hacerse a causa de la leucemia, pero este procedimiento es muy caro y hay que ser trasplantados con un donante que tenga comprobada resistencia al VIH”, acotó.

Según recuerda Fox, este caso fue documentado por primera vez el año 2009 en la revista New England Journal of Medicine. Timothy Ray Brown fue entrevistado esta semana por la revista alemana Stern.

CIENTÍFICOS PERUANOS OPINAN

El caso del primer paciente curado de Sida abre puertas interesantes para nuevos tratamientos de la enfermedad, asi lo afirmó Eduardo Gotuzzo, reconocido médico peruano, infectólogo y jefe del Departamento de Enfermedades Infecciosas, Tropicales y Dermatológicas del Hospital Nacional Cayetano Heredia.

En diálogo con RPP Noticias, el doctor explicó que en este caso se reemplazó la médula ósea del paciente con Leucemia como último recurso, ya que las fuertes quimioterapias a las que fue sometido habían destruido la suya por completo.

Según Gotuzzo en este caso, luego de producirse el transplante, los médicos se dan con la sorpresa de que además de no aparecer células cancerígenas, tampoco aparece el virus del VIH, enfermedad que también padecía el paciente.

Para el especialista, todavía no está claro el modelo para hacer tratamientos ya que no es una medida que se pueda aplicar a todos los pacientes.

En este punto Gotuzzo coincidió con el doctor Elmer Huerta en que un camino para llegar a curar el Sida es poder determinar el defecto genético que hace posible la “resistencia natural” al VIH, condición presente en el donante de médula.
