Did a Bone-Marrow Transplant Cure AIDS?

Human Immunodeficiency Virus (HIV) is a pathogen so wily and protean that researchers rarely talk about "curing" infected patients, focusing instead on treatment or prevention. But in an announcement that caused a flutter of excitement and a wave of prudent skepticism, Berlin-based hemotologist Gero Huetter claimed Thursday that he has cured a 42-year-old man of AIDS through a bone marrow transplant.

The patient, an American citizen living in Germany, was suffering from advanced leukemia and AIDS two years ago when Huetter decided to treat the cancer with a bone marrow transplant at Berlin's Charité hospital. As a side experiment, he inserted the bone marrow of a donor naturally resistant to HIV, the virus that causes AIDS. (Researchers have long known that about 1% of Europeans carry a genetic mutation that makes their cells resistant to HIV infection.) Bone marrow produces the cells that HIV attacks. So, the thinking went, inserting marrow that produces HIV resistant cells might endow the patient with a means to repel the infection. Twenty months after the transplant, Huetter says, the man shows no signs of carrying the virus. (See stories of people surviving with HIV.)

So is this a viable cure for HIV? Not by a long shot. Even Huetter says that bone marrow transplants, which kill around a third of patients, are so dangerous "that they can't be justified ethically" in anything other than desperate situations like late-stage leukemia. Nor is it clear that Huetter's claim to have cured his patient is yet justified. HIV has a frustrating ability to hide in hard-to-detect "reservoir" cells in various parts of the body. Current anti-viral drugs, for example, can lower a patient's "viral load" to the point that HIV is undetectable in his or her bloodstream. But as soon as such patients are taken off anti-virals, the virus comes storming back.

Huetter's patient has not received anti-virals for two years, and remains virus-free even in the known HIV-hiding spots of brain and rectal tissue, according to Huetter's tests. But many researchers remain skeptical as to whether these tests have been thorough enough. Dr. Andrew Badley, director of the HIV and immunology research lab at the Mayo Clinic, told the Associated Press, "a lot more scrutiny from a lot of different biological samples would be required to say it's not present."

But there might be a glimmer of hope in the case. If the transplant does prove to have been a success and can be replicated, researchers say gene therapists might one day be able to re-engineer a patient's cells in such a way so as to change their bone morrow in the same way as a transplant, except without the dangers. Such a breakthrough, if it proves possible at all, would be "decades rather than years away," according to Ade Fakoya, a London-based clinician and senior advisor to the nonprofit Aids Alliance. The treatment would also likely prove too expensive to implement in developing countries where HIV rates are highest, although some proponents of gene therapy say it could eventually be done cheaply through an injection, like a vaccine. (Read a TIME cover story on AIDS.)

Ron Noble of the British AIDS charity Avert says that recent setbacks for research into an AIDS vaccine, along with multiple false hopes in the search for a cure, have caused many in the HIV activism community to view Dr Huetter's experiment warily. For many AIDS activists, bone marrow transplantation is also a loaded procedure that evokes a traumatic past: before anti-virals were widely introduced in the 1990s, it was the one of the aggressive and often fatal procedures doctors tried in their desperate effort to halt the epidemic; some of these transplants even used marrow harvested from baboons.

In light of that pessimism about "curing" patients with HIV, Huetter's announcement was barely discussed at a major international HIV conference in Glasgow today, according to Fakoya, who was attending the event. He said that more attention was paid to more prosaic methods of defense, such as early identification and testing programs. "I'm in the conservative camp — I don't think there will be a cure," he says. "But if you look at anti-viral treatment, data was provided at this conference confirming that you can live 30 years on [anti-viral drug] therapy, especially if it's initiated soon after infection. We are getting to a stage where HIV can be managed as a chronic illness. Now that's not great, but I have a feeling it's the best we can do for the foreseeable future."
In the 60's, people took acid to make the world weird. Now the world is weird and people take Prozac to make it normal.

As a reputed atheist, the reverential nature of his film was surprising, but Pasolini himself said &If you know that I am an unbeliever, then you know me better than I do myself. I may be an unbeliever, but I am an unbeliever who has a nostalgia for a belief.&

Wow, what the fuck! 1% of the Europeans, more like 1% of the elitists! Thats proof that AIDS is a man-made virus aimed at non-whites. Time better take that line off...

manipulated maybe, but it seems to have a longer history than was previously thought depending on what you believe..

This is one complicated virus. Too bad they still didnt figure out how it jumped from monkeys to humans. I think researchers should shift their focus to that.
