En concreto, se comparará la efectividad del tratamiento iniciado justo después de comprobar la presencia de infección frente al tratamiento iniciado sólo cuando el recuento de linfocitos CD4 ha disminuido por debajo de 250 células por microlitro de sangre.
La investigación, financiada por el Instituto Nacional de Alergia y Enfermedades Infecciosas (NIAID) de Estados Unidos, distribuirá aleatoriamente a los pacientes en esos dos grupos de tratamiento.
En el caso de la estrategia de inicio tardío, se prevé interrumpir el tratamiento antirretroviral cuando el recuento de linfocitos CD4 haya aumentado por encima de 350 por microlitro.
Algunos estudios han mostrado que, en general, el riesgo de complicaciones asociadas al VIH aumenta sólo cuando el recuento de linfocitos cae por debajo de 150. Ello sugiere que las personas infectadas pueden vivir sin necesidad de tratamiento durante largo tiempo.
La investigación se llevará a cabo en 21 centros estadounidenses y en varios de Australia.
