Immunodeficiency and Autoimmunity
Inborn errors of immunity (IEI) include primary immune deficiencies (PID) and are a group of more than 480 potentially serious chronic medical conditions. They are caused by defects in genes that control the immune system and can lead to frequent or severe infections, and other chronic immune system disorders, including autoimmune problems.
ASCIA Immunoglobulin Replacement Therapy (IRT) and Subcutaneous Immunoglobulin (SCIg) information is mostly not specific for IEI/PID, and can be used by other medical specialties.
The International Patient Organisation for PIDs (IPOPI) has released an educational video series on PIDs, to increase the understanding of early detection and treatments for these conditions.
Autoimmune diseases are a broad range of more than 80 related disorders that include rheumatoid arthritis, systemic lupus erythematosus (lupus) and vasculitis disorders (inflammation of blood vessels). They are thought to be inherited in many cases, but factors such as infections and some drugs (medications) may also play a role in triggering autoimmune diseases.
Autoimmune diseases are usually diagnosed using a combination of clinical history, blood tests and other investigations such as x-rays and a biopsy. In autoimmune diseases, the immune system attacks the body's own cells, tissues and organs, resulting in inflammation and damage, so treatments aim to relieve symptoms, minimise organ and tissue damage and preserve organ function.
