Yesterday was a good day.It was a good day because it was one of the days that shows that, sometimes, science and ethics do win out after all:
CHICAGO (AP) — A government agency has dropped plans for a study of a controversial treatment for autism that critics had called an unethical experiment on children.
The National Institute of Mental Health said in a statement Wednesday that the study of the treatment — called chelation — has been abandoned. The agency decided the money would be better used testing other potential therapies for autism and related disorders, the statement said.
The study had been on hold because of safety concerns after another study published last year linked a drug used in the treatment to lasting brain problems in rats.Chelation (kee-LAY’-shun) removes heavy metals from the body and is used to treat lead poisoning. Its use as an autism treatment is based on the fringe theory that mercury in vaccines triggers autism — a theory never proved and rejected by mainstream science. Mercury hasn’t been in childhood vaccines since 2001, except for certain flu shots.
But many parents of autistic children are believers in the treatment, and NIMH agreed to test it.The researchers had proposed recruiting 120 autistic children ages 4 to 10 and giving half a chelation drug and the other half a dummy pill. The 12-week test would measure before-and-after blood mercury levels and autism symptoms.The study outline said that failing to find a difference between the two groups would counteract “anecdotal reports and widespread belief” that chelation works.
Except that it wouldn’t have.
