Mastocytosis - from NHS Choices:
Mastocytosis is a rare condition caused by excessive amounts of mast cells gathering in body tissues. These cells release large amounts of histamine and other chemicals into the blood, causing symptoms such as a skin rash, itchy skin and hot flushes.

Helminthic Therapy and mastocytosis
Very few people with mast cell disorders/mastocytosis have tried HT, and the results so far are not very favourable. Also, in one isolated case study involving a young boy, cutaneous mastocytosis was exacerbated by a pinworm infection.
Mast cell mutations in general may not respond well to HT, and it's possible that HT may even make them worse, at least initially. So those with mast spectrum disorders may require a modified approach to the use of HT, including a very gradual introduction of helminths.
Mastocyte and eosinophil activation are the body's methods of trying to eradicate helminths, so mastocytosis and eosinophilia normally increase after inoculation. However, just as eosinophils decrease over time, mastocyte activation may also be dampened. And we know that helminths secrete IgG4 blocking antibodies and stimulate Tregs, both of which limit mast cell hyperactivity.
