CVID - Common Variable Immune Deficiency

[Who Me?]

It seems many with mecfs have this. I just got dx'd but doc is doing more testing to look for other autoimmune or primary immune issues.

I think he was surprised to find this since I have not had chronic infections. I do have low total immunoglobulin, low subset IgG 1 and 3, low IgA and high IgM.

Common Variable Immune Deficiency

Common Variable Immune Deficiency (CVID) is one of the most frequently diagnosed primary immunodeficiencies, especially in adults, characterized by low levels of serum immunoglobulins and antibodies, which causes an increased susceptibility to infection. While CVID is thought to be due to genetic defects, the exact cause of the disorder is unknown in the large majority of cases.
