Common variable immunodeficiency is a group
of disorders in which the immune system cannot make antibodies in
response to foreign substances that may cause infection. The main
features that separate CVID from other immunodeficiencies are low levels
of two specific antibodies, immunoglobulin A (IgA) and immunoglobulin G
(IgG).
Individuals with this condition develop more frequent infections,
particularly in the sinuses, lungs, and digestive tract. CVID symptoms
most commonly begin in early adulthood, but have been found in children as
young as two years. Though some cases of CVID are caused by known genetic
factors, the cause of most cases is unknown. CVID can sometimes be
treated by "replacing" antibodies into the body; this treatment
is called "immunoglobulin therapy".
