Ok had ik nog niet gezien. Komt relatief vaak voor.
“ CVID is a
relatively frequent form of primary immunodeficiency, found in about 1 in 25,000 persons; this is the reason it is called common. The degree and type of deficiency of serum immunoglobulins, and the clinical course, varies from person to person, hence, the word variable. An additional characteristic is a decreased IgA and/ or IgM level, or a low level of all three major types of immunoglobulins (IgG, IgA, and IgM). In some individuals, there are defects of the T cells, and this may also contribute to increased susceptibility to infections as well as autoimmunity, granulomatous disease, and cancer.”
In de USA alleen zouden dat 13000 patiënten zijn.
