Researchers report they are using helminths -- intestinal worms
-- to combat Crohn's disease, the miserable, incurable disorder of the
intestine characterized by abdominal pain, diarrhea, rectal bleeding, weight
loss, and fever.
In the study, about three-fourths of people with Crohn's
disease given pig whipworm in a popular drink went into remission, reports Joel
V. Weinstock, MD, professor of gastroenterology-hepatology and director of the
Center for Digestive Diseases at the University of Iowa College of Medicine in
The study was presented at a major medical meeting of digestive

Weinstock explains that there is solid logic behind the
Giving Worms Back to the People
Crohn's disease, like many other disorders, is a disease of the
20th century, he says. And one of the major differences between "now"
and then is that kids no longer get worms, Weinstock says.
"Children [in developed nations] are no longer exposed to
helminths," he tells WebMD. "Worms used to be around in their
gastrointestinal tract, in their bloodstream."
Helminths don't just sit around, he says; they help regulate
the immune system. And Crohn's disease is caused by inflammation of the small
intestine -- inflammation that appears to result from an inappropriate immune
response to normal gut bacteria.
Those observations, Weinstock says, led to the thinking that
the "deworming" of our children may be partly or fully responsible for
the emergence of diseases like Crohn's. It follows, therefore, that giving the
worms back to the people could re-educate the immune system, help regulate the
response to inflammation, and wipe out the disease.
"We're the only people in history who have lived without
worms," Weinstock says. "So we wanted to see if giving worms could be
