Nueva variante del VIH

Los investigadores han descubierto en los Países Bajos una nueva cepa de VIH muy virulenta y más perjudicial para la salud, según un estudio dirigido por investigadores del Instituto de Big Data de la Universidad de Oxford, en Reino Unido, y publicado en la revista ‘Science’.

Como ha demostrado la actual pandemia de coronavirus, las nuevas mutaciones en las secuencias genéticas virales pueden tener un impacto significativo en la transmisibilidad del virus y en los daños que causa. Durante muchos años se ha temido que esto pudiera ocurrir en el virus VIH-1, que ya afecta a 38 millones de personas en todo el mundo y ha causado 33 millones de muertes hasta la fecha, y ahora este nuevo estudio lo acaba de confirmar.

Los individuos infectados con la nueva "variante VB" (por subtipo virulento B) mostraron diferencias significativas antes del tratamiento antirretroviral en comparación con los individuos infectados con otras variantes del VIH.

Así, los individuos con la variante VB tenían una carga viral entre 3,5 y 5,5 veces mayor. Además, la tasa de disminución de las células CD4 (el sello distintivo del daño del sistema inmunitario causado por el VIH) se produjo dos veces más rápido en los individuos con la variante VB, lo que los puso en riesgo de desarrollar el SIDA mucho más rápidamente.

Al mismo tiempo, los individuos con la variante VB también mostraron un mayor riesgo de transmitir el virus a otras personas.

Responde al tratamiento
Los investigadores apuntan que resulta tranquilizador que, tras iniciar el tratamiento, los individuos con la variante VB tuvieran una recuperación del sistema inmunitario y una supervivencia similares a las de los individuos con otras variantes del VIH. Sin embargo, subrayan que, dado que la variante VB provoca un declive más rápido de la fuerza del sistema inmunitario, es fundamental que los individuos sean diagnosticados de forma temprana y comiencen el tratamiento lo antes posible.

Origen de la nueva cepa
La variante VB se identificó por primera vez en 17 personas seropositivas del proyecto BEEHIVE, un estudio en curso que recoge muestras de toda Europa y Uganda. Dado que 15 de estas personas procedían de los Países Bajos, los investigadores analizaron los datos de una cohorte de más de 6.700 seropositivos en ese país. Así se identificaron otros 92 individuos con la variante, procedentes de todas las regiones de los Países Bajos, lo que elevó el total a 109.

Al analizar los patrones de variación genética entre las muestras, los investigadores estiman que la variante VB surgió por primera vez a finales de la década de 1980 y en la de 1990 en los Países Bajos. Se propagó más rápidamente que otras variantes del VIH durante la década de 2000, pero su propagación ha disminuido desde aproximadamente 2010. El equipo de investigación cree que la variante VB surgió a pesar del tratamiento generalizado en los Países Bajos, no a causa de él, ya que un tratamiento eficaz puede suprimir la transmisión.

Sometimes we focus our attention on the news that sounds the most and we forget all the others. Hiv is again news no. It's always there just like other viruses that arrived and they're not going to go away so easy.

So its not just covid that we need to worry about. HIV a scary thought. Don't know how many more viruses we'll have to deal with in the future

excellent scientific publication on HIV viruses and their variants if they already know their mutuations as they have not been able to make a vaccine for such a degenerative disease we hope that soon it will find its cure

We must be careful then, today more than ever, because now there are variants of even diseases that had remained at one point, hopefully there are immediate solutions.

With these variants in the different diseases, the little progress that is automatically progressed is reversed, it is the story of never ending, when a definitive cure will be found.

I read it here in the paper. Also that this variant was discovered here in the Netherlands. Strong mutations of the HIV virus would be highly undesirable. I really hope they'll find a vaccine for that too.

Well, since new variants of Covid began to emerge, it should also have been thought that variants of other diseases could emerge.

Just as HIV treatment progresses, this comes from the fact that there is another variant, it is a terrible thing to know and hopefully it is not a total madness.

Interesting how diseases and viruses sprout more because of the human being who does not learn and pretends to play God as it has been with covid, I hope this does not become something serious over time.

Your post is very interesting and important. It is scary and it is good that it is so. In the 90s we were very afraid of HIV but now it is no longer talked about, as if it did not exist and young people almost do not know what it is nor do they protect themselves.

Well Doctor, call me a conspiracy theorist if you want. Did some of the vaccines not include the HIV at one stage? https://www.forbes.com/sites/roberthart/2020/10/20/researchers-warn-some-covid-19-vaccines-could-increase-risk-of-hiv-infection/?sh=304d86a63740  Just wondering?

@Arukah Tsur totally in the initial investigations at the beginning of 2020 in the molecular study of the corona virus a molecule that also had the HIV virus was detected, so the first thing that was thought of was genetic manipulation, it is not old that news, we just hope it is not true.

@Dewaputra at the research level if it is important, since if the origin is known, it is determined where the strain is strongest and where they will start the first line of defense.
