5 years after stem cell transplant, ‘Berlin Man’ has no doubt unique treatment cured HIV

By Associated Press, Published: September 12

ST. LOUIS — The first person reportedly cured of HIV said Wednesday he is hopeful that medical advances will allow others suffering from the virus that causes AIDS to be cured, too.

Timothy Ray Brown of San Francisco is known as “The Berlin Patient” because of where he was treated. He and the doctor who treated him, Gero Hutter, made their first joint appearance in the U.S. on Wednesday when Hutter spoke at a symposium on gene therapy at Washington University in St. Louis.

Scientists are studying whether gene therapy can be used to rid the body of HIV. Some doctors remain skeptical that Brown, 46, is cured. His case was first reported in the media in 2008 and described in the New England Journal of Medicine in 2009.

Brown and Hutter, in an interview with The Associated Press during the symposium, said the passage of time is further proof that Brown is cured. Hutter cited the same five-year standard after which some cancer patients are said to be cured.

Brown was diagnosed with HIV in 1995. In 2006, he also developed leukemia while living in Germany. Hutter performed a blood stem cell transplant using a donor with a rare gene mutation that provides natural resistance to HIV. Hutter said that resistance transferred to Brown.

Brown said he feels great, has not needed HIV medication since the 2007 surgery, and is now active in a foundation named for him that seeks a cure for HIV.

Brown grew up in Seattle and moved to Germany in 1993. After the HIV diagnosis, he started on medication to prevent him from developing full-blown AIDS.

He was attending a wedding in New York in 2006 when he became unusually tired. An avid cyclist, within weeks he could barely ride the bike and eventually was diagnosed with leukemia.

Brown underwent chemotherapy but needed a blood stem cell transplant and turned to Hutter, a blood specialist at Heidelberg University.

Hutter suggested they seek a donor with a certain cell feature that gives them natural resistance to HIV infection. Only about 1 percent of the northern European population has this feature. Hutter theorized that a transplant from such a donor could make the recipient resistant to HIV.

Hutter said no one apparently had tried this, and his idea received mixed reaction from other doctors. “Some were very excited, but many were skeptical,” he said.

But within weeks, Hutter said, tests showed promise that Brown was cured.

“I don’t know if I really believed it was cured” until the case was described in the New England Journal of Medicine, Brown said.

Earlier this year, doctors in California found traces of HIV in Brown’s tissue, leading to speculation that the disease had returned. But Hutter said the traces are remnants of the disease that can’t replicate or cause a recurrence.

The symposium in St. Louis was hosted by the university’s Biologic Therapeutics Center, which seeks to advance the use of gene therapy. Speakers said gene therapy has helped treat cancer, hemophilia and other diseases.

So far, Brown is the only person believed to have been cured of HIV. Hutter began procedures in 2008 with 12 other people who had both HIV and cancer, but some were too sick to undergo treatment, and others couldn’t find matching donors or ran into other roadblocks.

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
 
There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.
 
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
