News on Helminthic Therapy: Colitis Case Study, Adult Autism Clinical Trial
The hygiene hypothesis of allergies and autoimmune conditions offers one explanation for why these disorders have been on the increase for the last few decades. Infectious diseases have declined greatly over the same time period. We no longer have the epidemics of cholera, yellow fever, typhoid, small pox, and many other microbial illnesses that plagued our ancestors. Perhaps our immune systems need some amount of infection in childhood for proper development. “Uneducated” immune cells may be more likely to attack our own tissues. This hypothesis was first published in 1989.
Along this line of thinking, some researchers have suggested that a chronic, mild infection could reduce the damage produced by autoimmune conditions. Helminthic worms have been chosen as the ultimate natural anti-inflammatories. These parasites live in the intestines and generally produce no symptoms. Reference 1 explains that helminths are regarded as “master manipulators of the host immune response”.
I reported in July, 2010 about a clinical trial using helminths to treat multiple sclerosis. There are two new developments in helminth research:
1. A case study from the University of California reported that a patient with ulcerative colitis used Trichuris trichiura (a type of helminth known as whipworm) to treat his symptoms. His disease went into remission, and colonoscopy examination showed improved mucus production in the intestinal lining.
2. A clinical trial using helminths to treat adult autism is recruiting participants. The Mount Sinai School of Medicine in New York is conducting this study with the assumption that the worms can reduce neuroinflammation.
Helminthic therapy is not yet approved by the U.S. Food and Drug Administration for any condition, but it is advertised on the Internet. Researchers in the UK suggested data from animal studies and human clinical trials may be useful in developing new anti-inflammatory drugs to mimic what the helminthic worms do naturally. It is assumed that helminths secrete molecules to inhibit the human immune system and ensure their own survival as parasites.
We value and respect the experiences of all of our HERWriters, but everyone is different. Many of our writers are speaking from personal experience, and what's worked for them may not work for you. Their articles are not a substitute for medical advice although we hope you can gain knowledge from their insight.

How about just giving people the worms to treat the diseases so they don't have to keep taking pills? The worms used in the studies are so small you can't see them.

Me and my colleagues authored one of India's most extensive reports on clinical trials. Drop me a mail if you are interested in a copy. My email is ntaluk@gmail.com.
Some of the topics we included are:
- Market Trends
- Growth Drivers
- Regulatory Bodies and Framework
- Major Players.
-Etc.
We interviewed over 200 individuals and firms to collect the data in what we believe is one of the most detailed study on the subject in India.
