Hi
@Frannon18 Not as medical advice or opinion:
The immune system is thought to have two main 'arms' or types of action which work in concert.
An imbalance in the action of these arms is thought to lead to auto-immune conditions such as T1D, coeliac disease and so on.
Some years back researchers of coeliac disease thought that by stimulating the underacting or 'lazy' arm of the human immune system that the overactive arm might be reduced in its troublesome effect.
Since a dose of tapeworm could trigger the 'lazy' arm beginning in the intestine, it was thought that this might dampen down the deleterious effects of antibodies produced by the over active arm in coeliac disease, which is mainly focussed in the intestine.
www.ncbi.nlm.nih.gov/pubmed/25248819. in 2014
The number of studies have been on low numbers of people and have shown that a percentage of persons with coeliac disease subjected to hookworm infection have not reacted to challenges with gluten, a protein found in wheat and other grains which usually would have triggered a response.
Important to know is at the end of the timed hookworm infection the patient are given anti-worm treatment and tested to ensure the infection has been eradicated.
How one might get from this to diabetes I am not sure. But the above is the only reference to hookworm infection for treating auto-immune disease that I know of.
