Helminthic therapy, a type of Immunotherapy, is the treatment of autoimmune diseases and immune disorders by means of deliberate infestation with a helminth or with the ova of a helminth. Helminths are parasitic worms such as hookworms. Helminthic therapy is currently being studied as a treatment for several (non-viral) auto-immune diseases including Celiac disease,Crohn's disease, multiple sclerosis,asthma,and ulcerative colitis.Autoimmune liver disease has also been demonstrated to be modulated by active helminth infections.In addition to these autoimmune disorders, interest is increasing regarding diseases that involve inflammation but that are not currently considered to include autoimmunity as a component. For example, heart disease and arteriosclerosis both have similar epidemiological profiles as autoimmune diseases and both involve inflammation, and their recent increase in incidence cannot be solely attributed to environmental factors according to a recent paper proposing the eradication of helminths as an explanation of this discrepancy.
