Allergy Desperation: I'll Take a Parasite, Please


Everybody has a dream, even if it's as odd as wishing more people in the modern world had parasitic worms.

Jasper Lawrence so desperately wanted to be infected with a hookworm that he traveled to Africa and walked barefoot alongside open latrines in Cameroon to get one.

He got the idea from a documentary about a British researcher, David Pritchard, who has infected himself and spent decades researching why populations of people in the world where hookworm is common have virtually no hay fever, no allergies or asthma.


After years of suffering from adult onset asthma and allergies, years of driving himself "with stars in my eyes because [I] couldn't get enough air" to the hospital for treatment, and after years of taking the powerful drug prednisone, Lawrence thought he was ready to try a worm.

"It was only when I realized that there was no way I was going to obtain hookworm through buying it that I [decided I] would go to Africa," said Lawrence.

"I took my shoes off and I walked barefoot in open-air latrines. It was pretty much walking around barefoot in the areas. You didn't have to actually walk in the excrement," he said. "I got laughed at a lot, but some people were really hostile about it. ... While I was there my feet were very itchy, so I felt very confident that I was infected."

Within a few months, Lawrence said his asthma and allergy symptoms dissipated. He stopped prednisone. He started to exercise without worrying about an attack and, as a result, he said he lost 40 pounds.

Seeing an untapped treatment, Lawrence decided to go into business selling parasitic worms to people hoping to temper autoimmune conditions such as asthma, allergies, Crohn's disease, colitis and inflammatory bowel disease. He even has competition. At least one other online business offers patients worm therapy -- all without monitoring by the Food and Drug Administration.

Doctors and researchers say the worm therapy idea not only holds water, it is a promising wide-reaching treatment with FDA-monitored clinical trials for patients in several major U.S. cities.

But some doctors are not pleased by the new parasite treatment companies.

"It is a legitimate field, but it's been bootlegged," said Dr. Joel Weinstock, a professor of medicine at Tufts University, who has used his background in parasitology and specialist training in inflammatory bowel disease to study parasitic treatment for years.

"It could be within two or three years we have some really good things to treat disease," he said. But Weinstock pointed out that "99 times out of 100, most good ideas don't work out."

Weinstock said he and other scientists in Germany and the U.S. are currently working to test the parasitic therapy. He said it takes millions of dollars to clear a therapy under FDA oversight, and it costs money for a reason: The results are funneled into scientific research, and patients will be guaranteed a pure product from laboratories with oversight.

"The question is, what are you actually buying [from such companies]?" asked Weinstock, who added selling parasites over the Internet "hurts the science, and when people do this it makes people skeptical."

For $2,900, clients of Lawrence's company, Autoimmune Therapies, can swallow a dose of whipworm, or apply a Band-Aid of hookworms to penetrate the skin. The clients must submit a patient questionnaire, blood test and undergo a phone interview with a doctor before purchasing.
