What is Immune Neutropenia and Why Should You Care?
Published: Oct 07, 2023
Immune neutropenia is a condition where the body mistakenly attacks its own white blood cells, leading to a lower count of neutrophils. Understanding this condition can help you recognize symptoms and know when to seek medical advice.
Understanding Neutropenia
Neutropenia is when your neutrophil count drops below the normal threshold, making you more exposed to infections. Neutrophils are a type of white blood cell important for fighting off infections. The level at which infection risk increases is when the count falls below 500 cells per microliter.
The Immune Connection
In immune neutropenia, the body mistakenly identifies neutrophils as threats and destroys them. This can be due to antibodies or T-cells attacking the neutrophils. Most people with this condition have enough bone marrow reserve to avoid serious infections.
Who is Affected?
Immune neutropenia can affect anyone but is more common in certain ethnic groups and in children under 10. It’s often detected during routine blood tests or when investigating recurrent infections.
Symptoms and Risk Assessment
Many individuals with immune neutropenia show no symptoms, but some may experience frequent infections. The risk depends largely on the body's ability to produce new neutrophils. A normal bone marrow reserve often means less risk of infections.
