Medical Can parasitic worms be used as a treatment for diseases like ulcerative colitis?

Click For Summary
The discussion centers around the effects of the parasite Toxoplasma gondii, commonly associated with cats, on human behavior and personality traits. Research indicates that infected individuals, particularly women, may exhibit changes such as increased warmth, sociability, and impulsiveness, while also being more prone to guilt. Long-term infections appear to exacerbate these personality changes, challenging the idea that personality traits influence exposure risk. Notably, infected individuals are at a higher risk of car accidents due to reduced focus.Participants express curiosity about the prevalence of T. gondii and its potential links to mental health issues, including schizophrenia. There are inquiries about diagnostic tests for the infection and treatments available. The conversation also touches on the broader implications of parasitic influence on human behavior, raising questions about free will and the need for more research on the topic. The discussion highlights the complex relationship between parasites and host behavior, suggesting that T. gondii may subtly manipulate human actions in ways that warrant further investigation.

Many neurobiologists believe that "free will" is limited. Although man itself is least genetically determined creature we know, genetic / epigenetic causes may alter (steer) behaviors towards certain directions. And at the bottom of this it's not parasites, it's our biology who limits the "free will". Expression of certain genes (or lack thereof) and expression regulation can alter the way we behave in certain areas. Perhaps the most interesting ones being sex / aggressive / cooperation behaviors.

Besides, certain phenotypes will also change the social perception of others. Something as simple as your height and looks can mean some difference in the way other ppl rapport to you.

Sapolsky himself has a very interesting take on "free will", and IIRC he touches on this on his short Toxo talk.

I agree with them, between genetics and acquired responses to environment free will is very limited--I suppose it was more tongue and cheek :-p

bobze, Proton,

You (bobze) hit the NAIL on the head, I am still creeped out about it. However, the pragmatic realistic side of me says we must investigate, to either prove it true, of false with mitigating circumstances. I reported awhile ago that the NIH spends about 1/3 of it's budget on the study of the brain, why not start there with adjunct research and then see where it leads ?

Rhody...

I totally agree Rhody, my morbid curiosity would rather know if my behavior is being affect by a parasite. I suppose though, there are a great many people that don't think like you and I. Maybe they are all the infected ones :), smells like a zombie apocalypse to me! Lol

Maybe all the decision makers at NIH are toxo-positive...

Almost like some kind of sci-fi alien take over thriller conspiracy movie :biggrin: We might have to take matters to the extreme and invent the toxo inquisition.

Lisab,

One can only hope... :smile:

Okay, I was browsing news and, gulp... I read this... really, I am not making this up read for http://www.cnn.com/2010/HEALTH/12/09/worms.health/?hpt=T2"...
This month, the man's experience treating himself with parasitic worms was published in a medical journal. Depending on who's telling the story, his journey is one of a brilliant, empowered patient who found an amazingly effective treatment for himself and possibly others who suffer the same debilitating disease -- or the dangerous tale of an irresponsible medical rebel who could have killed himself and, by telling his story, might be inspiring others to do the same thing. As with any experimental treatment, you should not try this at home.

After he arrived, the doctor in Thailand extracted roundworm eggs from the stool of an 11-year-old infected girl. She gave the trichuris trichiura eggs to the patient, but he now faced another hurdle. The eggs needed to be cleaned in case the girl had hepatitis or some other infectious disease, and the eggs needed to mature for them to be helpful. It was up to him to clean the eggs and grow them in a process called "embryonation." "There wasn't much guidance on how to do it, since most people are trying to destroy these worms, not grow them," he says. But he managed to do it and ingested first a dose of 500 eggs and then another of 1,000. The worms could live in his intestinal track for many years.
and
By 2007, having made so much progress, the patient wanted to document his journey scientifically, and he contacted various researchers to help him, including P'ng Loke, who was then a postdoctoral fellow in immunology at the University of California-San Francisco. "He e-mailed me, and I ignored it," Loke remembers. "I was very skeptical at first, but he convinced me to have lunch with him." At their meeting, the patient laid out his story in more detail, and Loke became fascinated. "It's an amazing story, and he's quite possibly one of the smartest people I know," he says.

The lingering question I have is, once his symptoms are under control for good, hopefully, how does he rid himself of the worms. The article did not mention this. I assume by natural elimination ?

Rhody...

P.S. Evo... See what you started, first we have unwitting asymptomatic hosts (humans) with enlarged lymph glands, then we have behavior changes linked to other parasites, now this. People treating serious ulcerative colitis with these things, and living to tell the story. And the medical establishment balking at his approach. A fine mess, I must say.
