Primary immunodeficiencies (PIDs), also known as inborn errors of immunity (IEI) include more than 400 potentially serious disorders that can lead to frequent or severe infections, swellings (hereditary angioedema [HAE]) and autoimmune problems. PID/IEI discorders can be caused by defects in genes that control the immune system, and may be inherited.
Note: ASCIA Immunoglobulin Replacement Therapy (IRT) and Subcutaneous Immunoglobulin (SCIg) information is mostly not specific for PID, and can be used by other medical specialties.
