Autoimmunity and its association with regulatory T cells and B cell subsets in patients with common variable immunodeficiency

Lack of SAR in CVID is associated with the lack of specific autoantibodies in patients with autoimmunity. It is suggested that physicians use alternative diagnostic procedures.
