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.
Additionally, we cannot be diagnosed with lupus by our blood because we have an antibody deficiency AND we are on IGG therapy. What this means is 1. We can't give a positive result to a test like lupus (ana or antibody tests) and 2. If we do it COULD be from our donor antibodies we are getting. Docs need to understand this and look at physical presentation. Hope this helps.
How high is your IGG? Believe it or not now that mine run in the 1300's, my arthritis is nearly gone. I did not settle with just good levels, I pushed for increases so that I could help manage my extreme pain and fatigue. We cannot simply rely on "good" IGG numbers. Good luck
