haha I just randomly signed up for this forum. The guy in that news report was me, from an interview I gave earlier last year. I can say from experience that helminthic therapy does work VERY well for me at least. But it is no miracle cure. It does take about 6 months with most people to take effect, and not every one responds (response rates for Crohn's look to be around 90-95% based on small-scale surveys). While your immune system is adjusting to the worms, you will have side effects, such as fatigue, inflammation, fever, and digestive issues. These normally come on for a day or two, then go away, then come back during that 6 month period.
I've done quite well on it, but recently lost my worms and am getting redosed soon.
I take no medication when I am on the worms, I can eat anything I want pretty much (except for wheat, which I am allergic to). BMs are 100% normal (1 or 2 a day). Energy is fantastic (you do need to watch for anemia however).
lynx: Good questions. You are right that having too many worms can be dangerous. However, the dose I am on is tiny (25-35) and does not pose a health risk. Moreover, hookworm cannot reproduce inside the body (it is impossible).
With pig whipworm (what most of the medical studies use), you get a pharmaceutical product with strong quality controls. I am on human hookworm. With that, you are absolutely correct that there is a trust aspect with the provider of your worms. Mine provided me with negative tests for a variety of things (AIDS, hepatitis, strongyloides). I read all the medical research, talked with my GI doctor and an infectious disease researcher, and took the plunge. I also have a microscope and can check the guys out, as once the worms reach maturity they will start laying eggs.
Certainly beats the drugs, in my opinion.
