Saw the immunologist yesterday. He's convinced I don't have any allergies to the environment or foods. He ran tests and ruled that out. He said I have antibodies to my mast cells, hypersensitivity reaction.
It doesn't matter what I come in contact with - everything has the potential to cause an over active reaction, even emotions, stress, etc. That explains why I had a flare when my mom was sick and I was worried, explains why I had a flare before going to China. Bad stress and good stress, resulted in a over sensitivity reaction.
Drugs are a huge problem for me, one day it will be ok, the next I'll take the same thing and have a problem. Foods will do the same thing, but not always, it will depend on what else is going on that might trigger an over sensitivity reaction.
He thinks this is probably been going on the last several years of my lupus, prior to transplant. Might have contributed to why I did ok with rituxan, but than had a reaction to it, but did fine when I had it post transplant. Why one platelet infusions caused a problem, but another one didn't. Why it seems plaquenil causes itching and when I stopped it, I thought the itching stopped, but then it came back. Why I have been going absolutely crazy with itching and trying to figure out what a trigger might be and never could.
I'm on 2 antihistamines (Zrytech, Allergra) Zantac, which reduces H1 antihisomine, along with an nasal and an eye antihistamines, steroid nasal and eye drops. He also wants me to stay on the 5mg of prednisone and if I start to flare with itching, despite all the antihistamines and have any lung wheezing, to increase to 10mg and call him. He has me seeing him monthly, because he wants to make sure I'm not degranulating too many mast cells and causing increased lung symptoms.
He said there isn't much he can do about it, except treat the symptoms and it's autoimmune disease, so if the symptoms get severe again, despite the antihistamines, he'll try immune suppressants. Well golly......
I found this information and thought anyone else who has itching or allergy symptoms with their lupus might find it interesting too.
