AB There  are  two  basic  types  of  immunodeficiency  (also  termed  immune  deficiency):  (1)  primary  and  (2)  acquired  or  secondary.  Primary  immuno­deficiencies  are  a  class  of  disorders  in  which  there  is  an  intrinsic  defect  in  the  immune  system.  In  contrast,  acquired  or  secondary  immunodeficiency  states  occur  as  a  consequence  of  external  agents  such  as  infection  or  chemotherapy.  Over  300  distinct  primary  immunodeficiency  syndromes  have  been  recognized.
