30 years after first AIDS cases, hope for a cure
Question of the Day
Sunday marks 30 years since the first AIDS cases were reported in the United States. And this anniversary brings fresh hope for something many had come to think was impossible: finding a cure.
The example is Timothy Ray Brown of San Francisco, the first person in the world apparently cured of AIDS. His treatment isn’t practical for wide use, but there are encouraging signs that other approaches might someday lead to a cure, or at least allow some people to control HIV without needing medication every day.
“I want to pull out all the stops to go for it,” though cure is still a very difficult goal, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.
For now, the focus remains on preventing new infections. With recent progress on novel ways to do that and a partially effective vaccine, “we’re starting to get the feel that we can really get our arms around this pandemic,” Fauci said.
Nearly 30 million people have died of AIDS since the first five cases were recognized in Los Angeles in 1981.
About 34 million people have HIV now, including more than 1 million in the United States.
About 2 million people die of the disease each year, mostly in poor countries that lack treatment. In the U.S. though, newly diagnosed patients have a life expectancy only a few months shorter than people without HIV. Modern drugs are much easier to take, and many patients get by on a single pill a day.
But it wasn’t that way in 1995, when Brown, an American working as a translator in Berlin, learned he had HIV. He went on and off medicines because of side effects but was holding his own until 2006, when he was diagnosed with leukemia, a problem unrelated to HIV. Chemotherapy left him so sick he had to be put into a coma to allow his body to recover.
“They didn’t know if I’d survive that,” Brown said.
Dr. Gero Huetter, a blood cancer expert at the University of Berlin, knew that a transplant of blood stem cells (doctors used to use bone marrow) was the best hope for curing Brown’s cancer. But he aimed even higher.
“I remembered something I had read in a 1996 report from a study of people who were exposed to HIV but didn’t get infected,” Huetter said.
But transplants are grueling. Huetter would have to destroy Brown’s diseased immune system with chemo and radiation, then transplant the donor’s cells and hope they would take hold and grow. Many cancer patients die from such attempts and Brown wasn’t willing to risk it.
His mother, Sharon Brown of Seattle, agreed.
“Before I knew he had HIV I used to have nightmares about it,” and gambling on a transplant to try to cure it didn’t seem smart when the cancer seemed to be in remission, she said.
