4 Eclectic Science and Regulatory Compliance: Stories for the Curious
A Few Surprises
In modern times, it would appear unlikely to find other instances where pathogenic
organisms currently are used to treat a disease. Surprisingly, however, parasitic worms are
being studied as Investigational New Drugs to ameliorate autoimmune diseases.
Eight studies now are listed on the US National Institutes of Health (NIH) website.
Seven employ Trichuris Suis ova (pig whipworm) as treatment for multiple sclerosis,
ulcerative colitis, autism, food allergy or Crohn’s disease.22 Fortunately, the porcine vari-
ety cannot survive inside the human body for very long.
Studies suggest helminths (parasitic worms) may ease the symptoms of autoim-
mune diseases by increasing mucus production.23,24 The mucus production boost may
help calm an excessively aggressive immune system. Production seems to correlate to a
carbohydrate metabolism increase in the tissues where the helminths reside.
The other study on the NIH website, and even more strange, is one designed to
inoculate celiac disease patients with human hookworm Nector Americanus to evaluate
immunity and gluten sensitivity.
The second surprise relates to bloodletting. The procedure still is used to treat
hemochromatosis and is the best method for removing excess iron from the body. One
half-liter of blood is removed each week until the body’s iron level is normal.25 This may
require many months or even years to accomplish.
