Cytopenia
Cytopenia is a reduction in the number of mature blood cells. It can have many causes, and commonly occurs in people with cancer being treated with radiation therapy or chemotherapy.
Types
- Anemia – a reduction of the red blood cells in the body.
- Leukopenia – a deficiency of white blood cells, or leukocytes
- Neutropenia – a type of leukopenia, with a specific deficiency in neutrophils
- Thrombocytopenia – a deficiency of platelets
- Pancytopenia – when all three types of blood cells; red blood cells, white blood cells, and platelets, are all deficient. This is a life-threatening disorder that is a characteristic of aplastic anemia.
Symptoms and signs
The symptoms of cytopenia vary depending on the type.The symptoms of anemia include:
- Fatigue
- Weakness
- Shortness of breath
- Poor concentration
- Dizziness or feeling lightheaded
- Cold hands or feet
- Frequent infections
- Fever
- Easily bleeding or bruising
- Difficulty to stop bleeding
- Internal bleeding
Causes
- Chemotherapy
- Malignant tumors
- Antacids
- Antibiotics
- Anticonvulsants
- Antimalarials
- Antivirals
- Cardiac drugs
- Diabetes drugs
- Hyperthyroid drugs
- NSAIDs
- Rheumatoid arthritis drugs
Treatment
- Epoetin alfa, a synthetic erythropoietin that stimulates stem cells to produce red blood cells.
- Darbepoetin alfa stimulates red blood cells but requires less daily doses and less disruption in activities.
- Growth factors, synthetic versions of substances involved in stimulating red and white blood cell production, such as G-CSF and GM-CSF.
Bone marrow and stem cell transplantation are effective for many types of cytopenias. However, when a compatible donor cannot be found, immunosuppressive therapy is also common.
