- An Old New Drug for AIDS

- <p>The notorious sedative thalidomide may give doctors another
- weapon to fight a modern plague
- </p>
- <p> Thalidomide has long been synonymous with tragedy. In the early
- 1960s, thousands of European women who took the sedative during
- pregnancy gave birth to children with no arms or legs, and only
- the vigilance of the Food and Drug Administration prevented
- a similar disaster in the U.S. But the old drug that once brought
- despair may one day generate hope for the victims of a modern
- plague. In an experiment that began in 1992, researchers at
- Rockefeller University are testing the possibility that thalidomide
- can fight the ravages of AIDS.
- </p>
- <p> Encouraged by laboratory results suggesting that the drug could
- suppress the AIDS virus (HIV) in cells grown outside the body,
- a team of scientists led by immunologist Gilla Kaplan gave thalidomide
- to a dozen patients in New York City and Thailand. After four
- to six weeks of therapy, some of them had gained between 10
- and 30 lbs. and their fevers had disappeared.
- </p>
- <p> No one believes a cure is at hand, but researchers hope thalidomide
- can slow the progress of the disease and buy precious time for
- patients. In the original test-tube trials, reported last week
- in the Proceedings of the National Academy of Sciences, the
- drug appeared to prevent some, but not all, HIV-infected cells
- from producing any new copies of the virus. Thalidomide apparently
- accomplished this feat by inhibiting a naturally occurring substance
- called tumor necrosis factor (TNF). Its purpose in the body
- is to fight cancer and infections, and a side effect of its
- activity is severe weight loss. In people who are infected with
- HIV, for some unknown reason, TNF also promotes production of
- the virus. "We thought that if we could inhibit TNF, then maybe
- we could decrease some of the clinical symptoms of AIDS," Kaplan
- says.
- </p>
- <p> Despite the early positive signs, Kap lan does not yet know
- whether thalidomide has decreased the amount of virus in her
- patients. Says Dr. Anthony Fauci, head of the National Institute
- of Allergy and Infectious Diseases: "Certainly this is encouraging
- enough to pursue other studies with larger numbers of people
- to see if the effect holds up." Already, the Rockefeller group
- has launched a second study of about 40 people. Unfortunately,
- the AIDS virus has a habit of evading most of the roadblocks
- scientists try to put in its way.
