Common Variable Immunodeficiency Support Group
Common variable immunodeficiency (CVID) is a group of 20-30 primary immunodeficiencies (PIDs) which have a common set of symptoms but with different underlying causes. CVID's underlying causes are different, but the result of these are that the body doesn't produce sufficient antibodies in response to exposure to pathogens.
I am so sorry, I did not mean to scare you with too much info about C-Diff.
Its important to remember that Even though CDiff is out there, IVIG works and that gives us a pretty good Immune system to fight off illnesses like C-Diff
I do not know about fungal infections in the upper respiratory system. All my issues are mostly GI related, but I had tons of fungal infections all over my body constantly. Once I started IVIG the rashes went away.
Again, I am sorry to have worried you and I hope that your thrush goes away. It is awesome that you have the chance to go to the Mayo Clinic. I would really like to hear what some of the best doctors in the world have to say about CVID and the struggles you are having.
Sending good thoughts your way, LuLu
