Study Notes
Definition of Leukopenia
- Condition characterized by a reduced number of leukocytes (white blood cells) in the blood.
Normal Range of Leukocytes
- Typical leukocyte count in adults ranges from 4,000 to 11,000 cells per microliter of blood.
Medical Causes of Leukopenia
- Certain medications, such as chemotherapy agents, can lead to decreased white blood cell production.
- Bone marrow disorders, including aplastic anemia and leukemia, affect the body's ability to produce leukocytes.
- Viral infections, such as HIV, can diminish leukocyte levels.
- Sepsis and severe infections can also cause leukopenia as the body utilizes white blood cells rapidly.
Autoimmune Disease Association
- Lupus is an autoimmune disease commonly linked with leukopenia, where the immune system mistakenly attacks leukocytes.
Symptoms of Leukopenia
- General symptoms include increased susceptibility to infections.
- Fatigue, emotional disturbances, and headaches are notable symptoms linked to leukopenia.
Indications of Infection
- A rising body temperature, or fever, in conjunction with leukopenia may indicate an ongoing infection.
