AB Allergic  disorders  are  among  the  most  common  problems  seen  by  pediatricians  and  primary  care  physicians,  affecting  over  25%  of  the  population  in  developed  countries.  In  the  most  recent  National  Health  and  Nutrition  Examination  Survey,  54%  of  the  population  had  positive  test  responses  to  one  or  more  allergens.  According  to  a  recent  National  Center  for  Health  Statistics  survey,  the  prevalence  of  food  and  skin  allergies  has  increased  over  the  past  decade;  with  prevalence  in  2015  of  5.7%  and  12%,  respectively.  While  the  prevalence  of  respiratory  allergies  has  been  stable,  it  is  still  the  highest  among  children  (10.1%).  In  children,  asthma,  allergic  rhinitis,  and  atopic  dermatitis  have  been  accompanied  by  significant  morbidity  and  school  absenteeism,  with  adverse  consequences  for  school  performance  and  quality  of  life,  as  well  as  economic  burden  measured  in  billions  of  dollars.  In  this  chapter,  atopy  refers  to  a  genetically  determined  predisposition  to  develop  IgE  antibodies  found  in  patients  with  asthma,  allergic  rhinitis,  and  atopic  dermatitis.
