Primary immunodeficiencies (PIs), also known as inborn errors of immunity (IEI), are not a single disease but rather a group of over 450 rare, chronic conditions. These conditions are characterized by a malfunctioning or missing part of the body's immune system.
Understanding Primary Immunodeficiencies (PIs)
PIs are a diverse group of disorders that disrupt the body's natural defense mechanisms. While each PI is unique, they all share a common thread: an impaired immune system.
Key Aspects of PIs
- Rarity: PIs are considered rare diseases.
- Variety: There are over 450 different types of PIs.
- Chronic Nature: PIs are typically long-term conditions.
- Immune System Dysfunction: PIs arise from defects within the immune system, where one or more components are missing or don't work correctly.
Examples of Problems Caused by PIs
- Increased susceptibility to infections.
- Autoimmune disorders.
- Inflammation.
