Worms - a medical miracle for arthritis sufferers?

Pig parasites can dampen inflammation in people.

Pig parasites can dampen inflammation in people.

Sufferers of painful autoimmune diseases could soon be prescribed a ‘new’ treatment that would effectively remodulate immune systems without involving potent biological drugs and the side effects that come with them. The patient just has to take a shot of pig worm eggs.

Biopharmaceutical company Coronado Biosciences is conducting clinical trials using the eggs of the pig whipworm to regulate immune activity. The treatment is centered on the “hygiene hypothesis,” which asserts that today’s sterile, germ-free homes can actually make us sick. Lack of exposure to pathogens could prevent immune systems from properly regulating, explained Dr. Bobby Sandage, CEO of Coronado.

Worms co-evolved with all animals, dating as far back as dinosaurs. Foreign bodies usually trigger an acute immune response when they infect animals, but the worms figured out a way to the dampen it, creating a potentially symbiotic relationship with the host organism. Anti-inflammatory cytokines - the messenger cells of the immune system - are created and produce a therapeutic response that could treat chronic diseases.

Pig parasites were chosen because they cannot thrive in the human body. The eggs remain solely in the GI tract and will eventually die out or be digested, Sandage said. There is no permanent infection, and there is little risk of transmitting the worms to another person. There’s also little risk of the worms evolving, he noted.

“They can’t be human parasites pathogen because those actually cause problems,” Sandage said. As for drug delivery - you wouldn’t need to swallow a handful of worms. Patients just drink a colorless, odorless, and tasteless solution. Today’s most common biological drugs must be injected subcutaneously.

My autoimmune disease, which is similar to Rheumatoid Arthritis, began while I was a senior in high school. The treatments can be toxic and over the long term. Chugging down a whipworm shooter might sound odd, but is preferable to taking my medicines indefinitely because the drugs can carry risks of health problems.

I’m certain that many other autoimmune suffers would agree to at least try it, and hundreds already are.

Coronado is initially focusing on Crohn’s disease, MS, type 1 diabetes, and ulcerative colitis. Clinical trials for autism and rheumatological diseases could follow. Phase II trials are underway for Crohn’s, MS, and ulcerative colitis patients to determine the effectiveness of those treatments. Phase III trials could begin as soon as 2014, and the product could come to market as early as 2016-2017, Sandage said.

No **** Sherlock
'Hygiene Hypothesis'....


... It's another No **** Sherlock moment. Fundamentally what is your Immune System for and, how does it keep in condition and evolve - By being exposed to nasty stuff.

Non-specific immune response
There are many ways to illicit the same immune response - without ingesting potential parasites. There are a wide variety of organic compounds that produce immune responses including the cytokine cascade referenced above. Probably the safest is the simple polysaccharide Beta D-Glucan isolated from the cell walls of bakers yeast - and is so early evolved and retained to have receptor sites on hemocytes from hydra's to humans.

i think you misread
I think you misunderstand the treatment here. The worms do not trigger an immune response, they *suppress* the body's immune response. For folks with auto-immune diseases, this what is needed. You are correct that triggering an immune response is relatively easy, doing the opposite is definitely not or we'd have decent treatments today.

revulsion
even as i cringe i welcome this new path "nosy" humans are treading.
yes, even before we formulized science, it was plain curiosity or nosiness, if you will.
i cringe even though i'm not autoimmune but if i were, i'm sure i would take the worm.

Just go read the Agriculture Department's regulation of insects in food...
...the rules are 'esthetic' not safety and the maximum percentage of insect 'parts' is up to the inspector...

You are an omnivore and can pretty much eat anything not directly toxic or parasitic/infectious...and even a certain amount of things which are directly toxic or parasitic/infectious.

I might wait....
.. I might wait until the word 'little' is changed to 'zero' in the comment in the article "Theres also little risk of the worms evolving" :o)

...and wait...and wait...and wait.
No biologist will ever likely say 'zero' chance of anything. The question is not of absolute safety--doesn't exist. The question is relative safety to other possible treatments correlated with success and probable side-effects.

Given that the vast majority of the human body is made of bacteria, and we are far from a single organism, adding an additional symbiote is nature's most usual way of adding features...more so than genetic changes.

Ignorance is bliss...
I think that if you (or anyone) were suffering from an autoimmune disease, you wouldn't be able to drink that shot of pig worm eggs fast enough... Pain, foggyness in the brain, general malaise all the time, fatigue, headaches, etc... Drugs that have side effects so bad that a person usually flips a coin to decide which is worse, death or misery. While this is not a cure, it is very welcome among those who suffer and can barely tollerate the meds.

These are just eggs?
If it meant I would no longer live with constant pain, I'd happily let a couple of living worms take up residence in my gut.

What's in your Navel
Saw this today. Quite interesting on the subject of Immune Systems.
