| Stem Cell Transplant Cures HIV In 'Berlin Patient'
http://www.huffingtonpost.com/2010/1..._n_796521.html  Quote:
On the heels of World AIDS Day comes a stunning medical breakthrough: Doctors believe an HIV-positive man who underwent a stem cell transplant has been cured as a result of the procedure.
Timothy Ray Brown, also known as the "Berlin Patient," received the transplant in 2007 as part of a lengthy treatment course for leukemia. His doctors recently published a report in the journal Blood affirming that the results of extensive testing "strongly suggest that cure of HIV infection has been achieved."
Brown's case paves a path for constructing a permanent cure for HIV through genetically-engineered stem cells.
Last week, Time named another AIDS-related discovery to its list of the Top 10 Medical Breakthroughs of 2010. Recent studies show that healthy individuals who take antiretrovirals, medicine commonly prescribed for treating HIV, can reduce their risk of contracting the disease by up to 73 percent.
While these developments by no means prove a cure for the virus has been found, they can certainly provide hope for the more than 33 million people living with HIV worldwide. Alongside such findings, global efforts to combat the epidemic have accelerated as of late, with new initiatives emerging in the Philippines and South Africa this week.

Oddly enough, first thing that came to my mind was some American intellectual getting pissed because of the bush admin's ban on stem cell research and now the US is behind.

I hope its true!
But I don't see how stem cells can cure a viral disease....maybe it just aids to prevent the symptoms..in any event

How was his AIDS cured? Is the term "cured" defined by having a sufficient CD4 count rather than the body being free of the HIV virus itself?
Big step forward for science, things like this experiment (eg. using hematopoetic progenitor cells to make more T-cells) have been going on forever glad to see one of them worked out, now on to the rest of 33 million people in the world who live with HIV =)

He wasn't at the AIDS stage -- AIDS (Acquired Immune Deficiency Syndrome) is a patient state where the natural defense T-cells are below a certain number in the body, leaving the host weakened to everyday threats like the flu virus, cancer, bacteria etc etc.
HIV is the virus that causes this condition -- imagine that you are a collection of zillions and zillions of self-replicating bubbles called cells. On the surface of the cells are things called receptors, resembling key holes -- millions of different keyholes for different keys. Viruses are like keys, and when they enter the body and happen to "plug" into a keyhole that fits, trigger shitloads of things to happen. The HIV virus for example, plugs into the the body's defense T-cells, and tells it stop replicating itself, and instead make more HIV viruses ("keys") which in turn infect other T-cells etc.
Under normal circumstances, your body has units that move around and look for foreign dangers such as bacteria or viruses. Once found, these units attack the bacteria or viruses, and present fragments of them to T-cells, which then make other units to look for, and attack the specific bacteria or virus. Such T-cells are termed "activated" as they now have a target in the body.
The HIV virus however, preferentially attacks such "activated" T-cells, rendering the natural defense system weaker.
What this study found, is that by introducing cells that give rise to new T-cells (unactivated), by way of stem cells, these T-cells have effectively managed to rid the body of existing HIV viruses.

1.) They had to find a "mutant" strain of stem cell that would give rise to T-cells that would be resistant to the HIV virus - this mutation happens in 1% of all caucasians, and 0% of asians/blacks.
2.) They had to use chemotherapy to kill ALL of the patient's original T-cells, meaning that their natural immune system was killed off to zero, or it would attack the new mutant "foreign" stem cell T-cell. Such procedures have 25-30% fatality rates.
3.) The stem cell replacement therapy is extremely expensive and time consuming, and thus would never be feasible for large populations....
Just the first 2 reasons alone make the statistical success rate (0.01 x 0.25) = 0.0025

an actual cure for "AIDS" seems unlikely, or in the least, inneffective treating the vast majority of the people with it
prevention like this is really the only way there will be until there is somthing that stops AIDS completely and rebuilds the immune system in one shot
50 million Africans arent going to be lining up for 3 time a week treatments, even when it's free
