PLEASANTON, California, May 19, 2011 /PRNewswire/ -- Roche (SIX: RO, ROG; OTCQX: RHHBY) ha anunciado hoy que ha recibido la marca CE para el uso expandido de su nueva prueba de VIH(1). Esto permite utilizar la prueba en entornos de laboratorio más pequeños. Antes la diversidad genética en rápido crecimiento del VIH-1(2,3) y su implicación para la eficacia de la terapia antirretroviral, el nuevo enfoque objetivo doble de Roche asegura una mejorada fiabilidad de los resultados de prueba y más confianza en la evaluación de las cargas virales. Desde que Roche introdujo esta innovadora estrategia en 2008, se han realizado más de 3,2 millones de pruebas utilizando el enfoque de objetivo doble para supervisar a pacientes con VIH en terapia antirretroviral.

"Este enfoque de objetivo doble mejora la capacidad de los médicos y laboratorios de obtener información fiable sobre los pacientes infectados por VIH", dijo Paul Brown, PhD, responsable de Roche Molecular Systems. "Roche se compromete a desarrollar y ofrecer nuevas herramientas de diagnóstico como este enfoque objetivo doble que servirá mejor a todos los laboratorios que realizan pruebas de carga viral para pacientes con VIH, incluyendo laboratorios que realizan ensayos clínicos y estudios de investigación que tienen necesidades específicas".

La estrategia objetiva doble

La estrategia objetiva doble mejora la precisión para cuantificar los subtipos de VIH-1 evitando que los efectos de correspondencias raras en los sitios de vinculación de imprimador/sonda de una región objetiva detectando simultáneamente y amplificando dos regiones separadas del genoma del VIH-1. La prueba utiliza el High Pure System Viral Nucleic Acid Kit para la preparación de espécimen manual y el COBAS TaqMan 48 Analyzer para la amplificación y detección automatizadas.

Acerca del VIH

En ese mismo año, 2,6 millones de personas se infectaron con VIH, casi un 20 por ciento menos que a finales de los noventa.(4) El tratamiento antirretroviral altamente activo (HAART) y las pruebas de carga viral, una prueba para determinar la cantidad de VIH circulante, han contribuido a un aumento estable en esperanza de vida con personas infectadas con VIH en 13 años.(5)
