[Clinical manifestations and late diagnosis of common variable immunodeficiency].

Background: Common Variable Immunodeficiency (CVID) is the most frequent type of severe primary immunodeficiency (PID). Clinical manifestations of CVID occur at any age; nevertheless, they are more frequent between the age of 6 and 10 years, and between the age of 20 and 40 years. In medical literature, there are hardly any diagnostic reports on CVID after 50 years of age.
