Wormy Cocktail Fights Crohn's Disease

Unconventional Approach Re-educates the Immune System, Relieving Symptoms
WebMD Health News

May 19, 2004 (New Orleans) -- Call it the medical edition of Fear Factor.

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 Iowa City.

The study was presented at a major medical meeting of digestive disorders experts.

Weinstock explains that there is solid logic behind the unconventional approach.

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 therapeutic."
