'Boston Patients' Still HIV Free After Quitting Antiretroviral Meds
ananyo writes "Two men with HIV may have been cured after they received stem-cell transplants to treat the blood cancer lymphoma, their doctors announced today at the International AIDS Society Conference in Kuala Lumpur. One of the men received stem-cell transplants to replace his blood-cell-producing bone marrow about three years ago, and the other five years ago. Their regimens were similar to one used on Timothy Ray Brown, the 'Berlin patient' who has been living HIV-free for six years and is the only adult to have been declared cured of HIV. Last July, doctors announced that the two men — the 'Boston patients' — appeared to be living without detectable levels of HIV in their blood, but they were still taking antiretroviral medications at that time."
The story reports that they have only been off of medication for seven and fifteen weeks and they won't know for a year, but signs are looking positive.
The only real cure we have for this disease.
The Internet King? I wonder if he could provide faster nudity.

suck it
...to butt fuck each other with impunity!
surely, signs are looking negative?
I remember recently there was some talk about research into curing some cancers by removing the patient's bone marrow, using HIV (ironically) to modify it, then transplanting that bone marrow back to the patient. What are the chances that something similar could be done here? To me it seems like all the pieces are in place; we know which gene confers some immunity, we are capable of editing targeted genes, and we can perform the bone marrow transplant. A marrow transplant would still be dangerous, but allotropic transplants are much less so since you get rid of the risk of graft vs host occurring.
There's a good chance this 'cure' will kill the patent. It works, but it's dangerous. The choice is between a treatment that may kill you now, or a disease that will kill you eventually. And either way you'll get to take lots and lots of drugs with nasty side effects.
The funny thing about medicine... as long as there's money to be made in selling the treatment you can be sure there won't be a cure. The treatment will always follow the bigger money.
A patient of chemo for cancer will take many thousands of dollars each year to combat their disease, so this is where cancer treatment seems to have stalled out in the US.
The "AIDS cocktail" has become quite inexpensive and costs a few bucks a week (until you get insurance numbers involved) so it's no surprising to see a more expensive treatment appear. A Stem Cell Transplant is a cash cow, with related costs adding up to $150-300k USD.
"signs are looking positive."
I hope not. Wouldn't that rather spoil the point?
now that this gen-X'er is old and married we have 20-minute at-home HIV tests and a cure is in sight

Is this something to do with a "Boston Marrige"? I thought we'd moved on.
systemd is Roko's Basilisk.
I wonder when some church is going to claim their did it.
And another will claim these people are no longer human.

Are these the same stem cells that the Christian Right was trying to ban for research?
Competition Good, Monopoly Bad.
re: "blood cancer lymphoma"
Leukemia is a blood cancer.
Lymphoma is, like the name suggests, lymphic system.
The previous "cure" was following a bone marrow transplant from someone with a mutation that made them highly resistant to HIV. This article makes it sound as though it was the transplant itself that cured the HIV. Does anyone know if these transplants also involved a resistant donor?
HIV levels go to undetectable in many HIV-drug patients, then reappear once off the drugs even if they have taken them over a decade. It was postulated there was a mystery resevoir for the virus. And/or it integrated into the victims DNA.
"but signs are looking positive" I think they mean signs are looking negative, lol.
one of my best friends is a biochem PhD who told me about this approach a few years ago but with a twist: he said they've isolated the sequence that causes the HIV resistance & that in a few yrs it should be possible to extract some of patients own marrow, splice it in, culture & replace. in theory you don't need to kill off patients own marrow as long as you can culture & inject enough to produce enough resistant T cells...
problem is even if (probably when) they solve the remaining technical problems it isn't scalable as a treatment & would likely only ever be affordable to the Magic Johnson class patients...
Unless I'm mistaken, that's what they used to say about chemotherapy.
They still do. Chemotherapy is quite dangerous and even in the best cases is pretty brutal on the patient. I've had the misfortune to see several people close to me go through chemo and it is an awful treatment with no guarantee of success. In some cases the chemo itself can be lethal.
Isn't it interesting that "statist" national healthcare systems, pharmaceutical patent busting, publicly-funded medical research etc, has was, WAY better outcomes than the joke privatized hell that passes for a healthcare system in America?
In no small part those results are due to those state managed health care systems getting a free ride on the back of research conducted by US companies. 12 of the top 20 medical device companies are based in the US. The US spends about $140 billion on medical research each year (roughly half from industry, a third from government and the rest from various philanthropic organizations) and much of the rest of the world gets to avoid this cost. It's much easier and cheaper to wait for someone else to figure out the cure and then just copy it.
While I'm not going to defend the flaws in the US healthcare system (which you rightly point out are many), part of the reason is because the US is paying the much of the cost of all the research everyone else gets to enjoy.
I wonder if the specific drugs used in the SCT conditioning regimen matter? The Berlin patient, AFAIK, received BEAM (carmustine, etoposide, melphalan and, significantly, cytarabine/ARA-C). ARA-C is antiviral in addition to cytotoxic - I wonder if the massive doses of ARA-C reduced the viral load enough that the graft-vs-host effect and immune reconstitution obliterated the rest of the HIV infection?
I would like to live for 10,000 years. I wonder if Stemcell transplant options could mkae that a possibility.
We're HIV Positive
