Primary immunodeficiencies

چکیده
Primary immunodeficiencies (PID) are inherited disorders of immune system function [1,2] characterised by absent or low response to infectious agents and a high prevalence of autoimmune manifestations and lymphoproliferative diseases. More than 120 PID in which a molecular defect causes the disease have been identified. The IUIS/WHO Experts Committee published a classification of all PID known to date [3]. A large group are diagnosed in childhood. The incidence of PID is not very high, except for IgA deficiency (IgA-D), which is mostly asymptomatic [4], and occurs in approximately 1/600 of the Caucasian population. However, many PID may be underdiagnosed and therefore, the real incidence of PID might be underestimated [5]. A simplified version of the IUIS classification [3] could be:
