Immune disorder

Immune disorder
Other namesAutoimmune disease
SpecialtyImmunology

An immune disorder is a dysfunction of the immune system.[1] These disorders can be characterized in several different ways:

  • By the component(s) of the immune system affected
  • By whether the immune system is overactive or underactive
  • By whether the condition is congenital or acquired

According to the International Union of Immunological Societies, more than 150 primary immunodeficiency diseases (PIDs) have been characterized.[2] However, the number of acquired immunodeficiencies exceeds the number of PIDs.[3]

It has been suggested that most people have at least one primary immunodeficiency.[4] Due to redundancies in the immune system, though, many of these are never detected.
