Extreme Therapy With Worms
This is a case study based on one man’s efforts to cure himself from ulcerative colitis. It describes the debilitating impact of the disease which are not commonly known. It also outlines the thoughts leading up to the decision to deliberately use worms.
The take home is that it is possible to apply this therapy safely and it is easy to actually end. However disease recurrence suggests that the therapy will be maintained for a lifetime.
We still do not know enough about the causes of these horrible diseases to cure them and as described herein, the present procedures are not terribly useful. In the end the patient is left to his own devices with a further compromised body.
This report made it on to CNN and comes right after the recently posted items and medical reports derived from this man’s work. It is noteworthy that he has had the disease under control now for six years.
Man finds extreme healing eating parasitic worms

Worms are damaging the patient's gut, researchers say, triggering a healing effect in areas affected by ulcerative colitis.

Experimental treatment for ulcerative colitis condemned by some as irresponsible
Researcher: Conclusion is that worms "were able to restore mucus production in his gut"
"Sometimes you really do have to take matters into your own hands," patient says
(CNN) -- One day in 2004, a 29-year-old man with a terrible stomach problem stepped off a plane from the
United States in . He wasn't there for the
sights, or the food, or the beaches. He had traveled thousands of miles for
worms -- parasitic worms whose eggs he intended to swallow by the thousands. Thailand
His doctor back home had told him his idea was crazy, that infesting himself with parasitic worms wouldn't do anything to help his ulcerative colitis, and in fact could make him very sick. The gastroenterologist had told the man if he pursued this course of treatment, he would refuse to be his doctor anymore.
"You'll be on your own," the man remembers the doctor telling him.
Indeed, he was on his own, standing in the office of a Thai doctor, asking her to pick the worm eggs out of an 11-year-old girl's stool.
Ten to 15 bloody bowel movements a day
This month, the man's experience treating himself with parasitic worms was published in a medical journal. Depending on who's telling the story, his journey is one of a brilliant, empowered patient who found an amazingly effective treatment for himself and possibly others who suffer the same debilitating disease -- or the dangerous tale of an irresponsible medical rebel who could have killed himself and, by telling his story, might be inspiring others to do the same thing. As with any experimental treatment, you should not try this at home.
The man -- who wants to protect his privacy, and be referred to only as "the patient" -- was 28 when he started having bloody bowel movements. Soon, he was having 10 to 15 bloody bowel movements a day.
"I was constantly running to the bathroom," he remembers.
Diagnosed with ulcerative colitis, nothing helped except high doses of steroids, which because of severe side effects, he could take only for limited periods of time. Soon, the patient became so sick he had to quit his job.

His gastroenterologist wanted to admit him to the hospital for an intravenous round of cyclosporine, a potentially helpful yet dangerous medicine that depresses the body's immune system and can increase the risk for getting cancer later in life.
If the cyclosporine didn't work -- and there was a 50 percent chance it wouldn't -- the doctor said his last hope was to remove his colon entirely, an extreme measure that would cause him to have to have a colostomy bag attached to him for the rest of his life to collect his stool.
"I was really at the end of the road," he says.
Meanwhile, the patient had gone on the internet and found an article in a medical journal by Dr. Joel Weinstock, chief of gastroenterology at Tufts University Medical School, which showed some ulcerative colitis patients found relief after ingesting the trichuris suis worm, a parasite that lives in the intestines of pigs.
The patient contacted Weinstock to ask him to treat him with worms, but Weinstock said no, since it wasn't approved for general use by the Food and Drug Administration and could only be done experimentally.
Other doctors also told him no.
"One very famous parasitologist in
told me he had
patients who were immigrants, and he could get the eggs from their stool,"
he says. "But he told me for legal reasons he couldn't do it. I understood
completely. What if something went wrong and I died? He'd be blamed." New York
The patient became more and more convinced worms could help him. Behind Weinstock's study was this observation: Inflammatory bowel diseases such as ulcerative colitis affect nearly one in 250 people in the
but are extremely rare in underdeveloped parts of the world, such as
Some experts believe parasitic worms might be part of the reason. When underdeveloped areas become developed, parasitic worms, also called helminths, become less common, and diseases such as ulcerative colitis become more common.
"We're not exposed now to helminths in places like the
, and that probably has an
impact," Weinstock says. "We've tried to separate ourselves from our
natural environment with our sterile water and our sterile food, and that's
saved lives, but there are negative consequences." United
A 'terrible choice'
"I was facing a terrible choice," the patient remembers, between going with the doctor's treatment idea, which he really didn't want to do, and looking outside the
for worm eggs to ingest. United States
He contacted researchers in various developing countries to ask if they could help him get his hands on some eggs. The researcher in
was particularly helpful, and he got on a plane to visit with her. Thailand
After he arrived, the doctor in
extracted roundworm eggs from the stool of an 11-year-old infected girl. She
gave the trichuris trichiura eggs to the patient, but he now faced another
hurdle. The eggs needed to be cleaned in case the girl had hepatitis or some
other infectious disease, and the eggs needed to mature for them to be helpful.
It was up to him to clean the eggs and grow them in a process called
"There wasn't much guidance on how to do it, since most people are trying to destroy these worms, not grow them," he says.
But he managed to do it and ingested first a dose of 500 eggs and then another of 1,000. The worms could live in his intestinal track for many years.
Three months later he had fewer bloody bowel movements, and soon, none at all. His bowel movements were normal. He felt fine.
From time to time, when his ulcerative colitis would flare up again, he'd extract eggs from his own stool, and clean, embryonate and ingest them. Again, his symptoms would go away.
A reluctant researcher
By 2007, having made so much progress, the patient wanted to document his journey scientifically, and he contacted various researchers to help him, including P'ng Loke, who was then a postdoctoral fellow in immunology at the University of California-San Francisco.
"He e-mailed me, and I ignored it," Loke remembers. "I was very skeptical at first, but he convinced me to have lunch with him."
At their meeting, the patient laid out his story in more detail, and Loke became fascinated.
"It's an amazing story, and he's quite possibly one of the smartest people I know," he says.
By the end of their meeting, they'd started to hatch a plan: Loke and his team would do colonoscopies to track the patient's ulcerative colitis and look for the presence of worms in his colon.
The researcher, now an assistant professor of medical parasitology at
and his team did a colonoscopy on the patient, which revealed an abundance of
worms and no signs of ulcerative colitis. New York
When the patient suffered a flare-up of his disease in 2008, a colonoscopy showed fewer worms and typical signs of ulcerative colitis.
When he ingested more eggs, a third colonoscopy showed the colitis was once again in remission.
The study was published in this month's Science Translational Medicine.
Why worms might work
To figure out why the worms seemed to be having this beneficial effect, Loke and his colleagues took a close look at the patient's immune system after he ingested the worm eggs. After ingestion, he had an abundance of cells that produce a protein called interleukin-22, which is important in healing the mucosal lining of the intestines.
"Our main conclusion is that the worms were able to restore mucus production in his gut," Loke says, adding that the mucus lining protects the intestines from harmful bacteria.
But others are not so convinced.
"The impact of mucus alone is not a scientific explanation for the possible improvement attributed to the worms," says Dr. Stephen Hanauer, a member of the board of trustees of the
of Gastroenterology. American College

was "irresponsible" for putting out a press release about the study,
and criticized media outlets such as CNN for reporting on it. New York University
"It's ridiculous and incredibly inappropriate," he says. "You're driving people to go on the internet and buy these worms, and these are potentially pathogenic organisms. These eggs can invade the systems of people who are immune suppressed and cause infections."
Loke says he and his team pointed out in the press release that the worms might hurt some people rather than help them.
"I agree no one should be trying to change their treatment" based on the paper's findings, Loke says.
The patient says he is also concerned others might try to copy him with potentially disastrous results, and so declined to explain exactly how he cleaned and embryonated the eggs.
He says he knows he took a risk by ingesting the eggs from a young girl in
but for him it was a better option than treatment with drugs that have
potentially dangerous side effects, or the removal of his colon. Thailand
