The sixth person to be cured of HIV may be a European man. |
Markneswin.blogspot.com came across this article at
www.msn.com and with regards to Health Day News, that on 20th of July 2023 ‘’ A
European man may be the sixth person to experience remission and be deemed
"cured" of his HIV infection, despite it being extremely uncommon.
The man had been treated with antiretroviral
medications since 2005 and underwent a stem cell transplant two years ago to
treat a rare form of blood cancer. He had been initially diagnosed with HIV in
1990.
One of only six people, a Swiss man in his 50s known
as the "Geneva patient," is thought to have either been completely or
possibly cured of HIV. According to NBC News, the others had stem cell
transplants as well for blood cancers.
The first five received the transplant from a donor
who had a rare genetic disorder that makes them HIV-resistant, but this man did
not, according to NBC News.
President of the International AIDS Society (IAS),
Dr. Sharon Lewin, told NBC News that the case is "great news" and may
"help in many ways in the work toward a cure." At
the IAS Conference on HIV Science, which takes place in Brisbane, Australia,
from July 23 to 26, scientists will learn more about the case.
The man who was taken off antiretroviral in
November 2021 has undergone sensitive tests for HIV signs. Sáez-Cirión and
others have found trace amounts of defective virus, but the possibility of
viral rebound remains a concern. The virus may persist in rare infected blood
cells or anatomical sites that have not been analyzed. This case may suggest
that what was once assumed impossible might be possible. Dr. Steven Deeks, a
leading HIV researcher at the University of California, San Francisco, believes
that eliminating most, if not all, of the reservoir with chemotherapy was the
key intervention.

The man with HIV has been experiencing
graft-versus-host disease, an immune reaction that can occur after a stem cell
transplant. The newly rebuilt immune system may have cleared the old immune
system, including any residual T-cells harboring HIV. The patient continues to
receive immunosuppressive drugs to prevent graft-versus-host disease and may
prevent the replication of any residual HIV. Scientists believe it will take
decades to develop an HIV cure, as it is considered unethical to perform a stem
cell transplant on someone without cancer due to the toxic treatment. HIV can
also hide in non-replicating immune cells, and current treatment only works on
cells actively producing new viral copies. Scientists will discuss
post-treatment control of HIV in infant boys, the impact of circumcision on HIV
risk in gay men, and the relationship between HIV and mpox at the IAS
conference.
