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.
Sorry you're having problems, perhaps IVIG will help. I'd been on IVIG for about 5 months when I was diagnosed with H. Pylori.
If you have diahrea issues I suggest you take 2 immodium every morning. That has been working well for me.
I noticed you are being treated at Mayo, I am as well, I was dx in April and have been doing sub q treatments since May. Wondering who your doc is there, and did they check you for Ciliac disease? I had a couple stomach biopsies, didn't find Ciliac or bacteria, but discovered a large ulcer that I didn't even know I had.
