There is also an article about this research at Web MD which says that 72% of people who used the treatment went into remission. These are amazing findings, however the research appears to be several years old. (Here's another medical article about Dr. Weinstock's research.)
Since I'm curious to learn whether this research is ongoing and if anything has come from it, I wrote to Dr. Weinstock asking about the status of his research. I haven't heard back yet, but I will post it here if I do.
I find this to be an amazing sounding treatment and I'm flabbergasted as to why I haven't heard about it before. Why are we only being given the option of expensive and dangerous drug therapies or invasive surgeries? I urge all my readers to look into this research and ask your doctor about it.
Here is an article on Wikipedia about it, it is called Helminthic Therapy.
UPDATE - April 7, 2010
I received a tidbit of information about this research from the CCFC:
The helminth exposure work connects with a wide range of "toll-like receptor" and "cell signaling" research that is ongoing among a number of different scientists across Canada. -Dr. George Tolomiczenko
