About-Aplastic anemia, also known as bone marrow aplasia, is a rare and serious condition that occurs when the bone marrow does not produce enough new blood cells. Bone marrow is the soft tissue inside the bones that produces red blood cells, white blood cells and platelets. Aplastic anemia can develop suddenly or gradually and may occur at any age. A shortage of red blood cells can cause tiredness and weakness, while low white blood cell levels can increase the risk of infections. A low platelet count can cause easy bruising and abnormal bleeding. In some cases, the exact cause of aplastic anemia is not known. It may develop when the body’s immune system mistakenly attacks the stem cells in the bone marrow. Other possible causes include certain medications, toxic chemicals, radiation, chemotherapy, viral infections and, rarely, pregnancy or inherited conditions.
Exposure to chemicals such as benzene and certain pesticides
Previous chemotherapy or radiation therapy
Certain viral infections
Autoimmune diseases
Certain medications that can affect bone marrow
Family history of inherited bone marrow failure disorders
Diagnosis-
Aplastic anemia is usually diagnosed with a medical history, physical examination and blood tests. The doctor may recommend the following tests:
Complete blood count (CBC) to measure red blood cells, white blood cells and platelets
Reticulocyte count to determine how well the bone marrow is producing new red blood cells
Peripheral blood smear to examine blood cells under a microscope
Bone marrow biopsy to examine the bone marrow and confirm reduced blood-cell production
Tests for viral infections and autoimmune conditions
Additional tests to identify inherited or other possible causes
Treatment-
Treatment for aplastic anemia depends on the severity of the condition, the patient’s age, overall health and the underlying cause.
Blood transfusions may be given to replace red blood cells or platelets and help control symptoms or bleeding.
Medicines may be used to suppress the immune system when the immune system is attacking bone marrow stem cells.
Stem cell or bone marrow transplant may be recommended for some patients, particularly younger patients who have a suitable donor.
Growth factors and other medicines may be used in selected patients to stimulate blood-cell production.
Treatment of the underlying cause may be necessary if aplastic anemia is related to a medication, infection, chemical exposure or another medical condition.
Complications-
Severe aplastic anemia can cause serious complications because the body does not have enough healthy blood cells.
Severe or recurrent infections
Excessive or life-threatening bleeding
Severe anemia and extreme weakness
Heart problems caused by severe or prolonged anemia
Iron overload resulting from repeated blood transfusions
Increased risk of other blood or bone marrow disorders in some patients
Prevention-
Many cases of aplastic anemia cannot be prevented because the exact cause is often unknown. However, some precautions may help reduce the risk.
Avoid unnecessary exposure to toxic chemicals such as benzene.
Follow appropriate safety precautions when working with chemicals or other potentially harmful substances.
Take medications only as directed by a healthcare professional.
Seek medical attention for persistent infections, unexplained bleeding or unusual tiredness.
When to See a Doctor-
Consult a doctor if you develop persistent fatigue, unusual bruising, frequent infections, unexplained bleeding or shortness of breath. Seek immediate medical attention for severe bleeding, high fever, difficulty breathing, chest pain, fainting or other symptoms that may indicate a serious infection or very low blood-cell counts.
Frequently Asked Questions (FAQs)-
1. What is aplastic anemia?
Aplastic anemia is a rare blood disorder in which the bone marrow does not produce enough new blood cells, including red blood cells, white blood cells and platelets.
2. Is aplastic anemia a type of cancer?
No. Aplastic anemia is not a cancer. It is a condition in which the bone marrow fails to produce sufficient blood cells. However, some symptoms may be similar to those of other blood disorders.
3. What causes aplastic anemia?
Aplastic anemia may occur because of an autoimmune reaction, certain medications, toxic chemical exposure, radiation or chemotherapy, viral infections and, rarely, pregnancy or inherited bone marrow disorders. In many cases, the exact cause is unknown.
4. What are the main symptoms of aplastic anemia?
Common symptoms include fatigue, weakness, pale skin, dizziness, headaches, shortness of breath, frequent infections, fever, easy bruising, nosebleeds, bleeding gums and prolonged bleeding from cuts.
5. How is aplastic anemia diagnosed?
Doctors generally use blood tests such as a complete blood count and reticulocyte count. A bone marrow aspiration or biopsy may also be performed to examine bone marrow and confirm the diagnosis.
6. Can aplastic anemia be treated?
Yes. Treatment depends on the severity and cause of the condition. Treatment may include blood transfusions, medicines that suppress the immune system, medicines that stimulate blood-cell production and stem cell or bone marrow transplantation.
7. Can aplastic anemia be cured?
In some patients, aplastic anemia can be cured with a stem cell transplant. Other patients may achieve long-term remission or improvement with immunosuppressive treatment and other therapies.
8. Is aplastic anemia hereditary?
Most cases of aplastic anemia are acquired rather than inherited. However, certain rare inherited conditions can cause bone marrow failure and may lead to aplastic anemia.
9. Is aplastic anemia life-threatening?
Severe aplastic anemia can be life-threatening because very low white blood cell and platelet counts can lead to serious infections and severe bleeding. Prompt diagnosis and treatment are important.
10 When should a person with symptoms see a doctor?
A person should consult a healthcare professional for unexplained or persistent fatigue, frequent infections, unusual bruising or bleeding, nosebleeds, shortness of breath or other concerning symptoms. Severe bleeding, high fever, difficulty breathing, chest pain or fainting requires urgent medical attention.
