Se trata de un metaanálisis que ha examinado los resultados de 13 estudios con más de 10.300 pacientes en total. Según los autores, la mayoría de estos trabajos ponen de manifiesto la influencia del género sobre la progresión de la infección por el VIH. Esto puede significar que las mujeres pueden desarrollar sida con menor carga viral que los varones, lo cual debería determinar cambios en las actuales pautas terapéuticas.
Más de tres cuartas partes de los estudios analizados indican que a similar estadio de la infección, las mujeres presentan una carga viral entre 2 y 6 veces inferior a la de los hombres. No obstante, la causa de esta diferencia entre sexos no está clara, según los autores, y que varios factores, entre ellos la edad, la raza, la vía de transmisión y los niveles hormonales, pueden estar implicados.
