Cancer chemotherapy is probably the most common cause of neutropenia. People with chemotherapy-related neutropenia are prone to infections while they wait for their cell counts to recover.
Neutrophils are manufactured in bone marrow — the spongy tissue inside some of your larger bones. Anything that disrupts neutrophil production can result in neutropenia.
Specific causes include:
- Kostmann's syndrome — a congenital disorder involving low production of neutrophils
- Myelokathexis — a congenital disorder involving failure of neutrophils to enter the bloodstream
- Leukemia and other diseases that damage bone marrow
- Myelodysplastic syndromes
- Radiation therapy
- Chronic idiopathic neutropenia in adults
- Vitamin deficiencies
Certain infections also can result in neutropenia, including:
- Hepatitis A
- Hepatitis B
- Hepatitis C
- Lyme disease
- Salmonella infection
- Sepsis — an overwhelming bloodstream infection that uses up neutrophils faster than they can be produced
- Other viral infections that disrupt the work of bone marrow
Conditions that destroy neutrophils in the bloodstream and that can result in neutropenia include:
- Rheumatoid arthritis and other autoimmune disorders
- Medications, such as antibiotics
- Hypersplenism — an abnormality of the spleen causing blood cell destruction
