, “the London patient.” Both, however, had been diagnosed with cancer and benefited from having a stem cell transplant to treat it, which replaced their immune cells with ones from donors that included cells that could block HIV infection. They also likely continued to harbor latent reservoirs of HIV, which have been eliminated in the patient Yu is describing.the first person, known as “the San Francisco patient,” in 2020.
Yu’s team has analyzed 1.5 billion blood and tissue cells from the Esperanza patient since 2017, searching for any hints of whole genetic virus material that would indicate a virus that could potentially still be active and replicate again. But they failed to find such evidence. They did, however, find fragments of viral genes that indicated this patient wasHIV patients
. Both of her patients belong to a group known as elite controllers, or people who are able to suppress HIV at very low, often undetectable levels with their immune systems, without the help of anti-HIV drugs. Researchers around the world are studying these people intensively; it’s not clear what percentage of those infected with the virus are able to naturally contain it with their immune systems, but Yu believes that the two patients she described suggest that there may be more.
“Many immune factors could be playing a role,” she says. “Now that we have a second case, there are probably many cases out there that may not know they have a sterilizing cure. Some may not even be aware they are infected. We are hoping to attract more patients; if we have a cohort of these extremely rare cases, then that will allow us to really analyze their immune responses in more depth and breadth and hopefully give us a hint about what immune factors contribute most to this status.
Since the first elite controllers were identified among sex workers in Africa in the 1990s, scientists have been studying their immune systems, looking at everything from the antibodies they make to the immune system’s highway made up of lymphocytes.
That is awesome!
Possible misdiagnosis? Doctors are not Gods and can make mistakes.
A good thing between all this shit
