The Expanding Spectrum of Primary Immune Defects

This article presents the general pediatrician with a broad overview of the rapidly expanding spectrum of primary immune deficiencies, which are diseases that go beyond the classic description of increased susceptibility to infections and also those with predisposition to autoimmunity, malignancy, and immune dysregulation. Readers are guided through the three proposed categories under the umbrella term of primary immune deficiencies. These categories are lack of function, inappropriate surveillance and clearance, and inadequate control immune dysregulation. This article presents an illustrative distribution of the interrelated groups of immune disorders. [Pediatr Ann. 2019;48(12):e489-e494.].
