Acquired sideroblastic anemia is a type of anemia, a condition where your body doesn’t have enough healthy red blood cells to carry oxygen throughout your body. This specific type of anemia happens because your bone marrow, where blood cells are made, has trouble producing red blood cells due to a problem with iron utilization. This means that even though your body may have enough iron, it’s not being used properly to make healthy red blood cells.
Acquired sideroblastic anemia is a condition where the bone marrow has difficulty producing healthy red blood cells due to problems with iron utilization, resulting in low levels of oxygen-carrying hemoglobin in the blood.
Types:
There are two main types of sideroblastic anemia: acquired and congenital. Acquired sideroblastic anemia occurs later in life due to factors such as exposure to toxins or certain medications, while congenital sideroblastic anemia is present from birth due to genetic mutations.
Causes:
- Alcohol Abuse: Excessive alcohol consumption can interfere with the body’s ability to absorb and utilize iron properly.
- Lead Poisoning: Exposure to lead, often through contaminated water or paint, can disrupt normal red blood cell production.
- Chemotherapy: Some chemotherapy drugs can damage the bone marrow, leading to sideroblastic anemia.
- Vitamin B6 Deficiency: Inadequate intake or absorption of vitamin B6 can impair the body’s ability to utilize iron effectively.
- Autoimmune Disorders: Conditions such as rheumatoid arthritis or lupus can cause the immune system to attack the bone marrow, leading to anemia.
- Hepatitis C: Chronic hepatitis C infection can lead to liver damage, which can affect iron metabolism and contribute to anemia.
- Exposure to Toxins: Certain chemicals or heavy metals can disrupt normal red blood cell production in the bone marrow.
- Myelodysplastic Syndrome: This group of disorders affects the bone marrow’s ability to produce healthy blood cells, leading to various types of anemia.
- Inflammatory Bowel Disease: Conditions such as Crohn’s disease or ulcerative colitis can interfere with nutrient absorption, including iron.
- HIV/AIDS: The virus can directly affect bone marrow function and also increase the risk of infections that contribute to anemia.
Symptoms:
- Fatigue: Feeling tired or weak, even after resting, is a common symptom of anemia.
- Pale Skin: Anemia can cause a lack of healthy red blood cells, leading to pale or sallow skin.
- Shortness of Breath: Low levels of oxygen in the blood can make it difficult to breathe, especially during physical activity.
- Dizziness or Lightheadedness: Anemia can cause a drop in blood pressure, leading to feelings of dizziness or faintness.
- Headaches: Reduced oxygen delivery to the brain can result in headaches or migraines.
- Cold Hands and Feet: Poor circulation due to anemia can cause extremities to feel cold to the touch.
- Chest Pain: In severe cases, anemia can strain the heart, leading to chest pain or angina.
- Weakness: Muscles may feel weak or shaky due to inadequate oxygen supply.
- Rapid Heartbeat: The heart may beat faster to try to compensate for low oxygen levels in the blood.
- Difficulty Concentrating: Anemia can affect cognitive function, making it hard to focus or concentrate.
- Brittle Nails: Changes in nail texture or color can occur due to poor circulation associated with anemia.
- Hair Loss: In some cases, anemia can lead to thinning or loss of hair.
- Cravings for Non-Nutritive Substances: Known as pica, this condition involves cravings for items such as ice, dirt, or clay and can be a sign of iron deficiency anemia.
- Restless Legs Syndrome: An uncomfortable urge to move the legs, especially at night, can be associated with iron deficiency anemia.
- Heart Murmurs: In severe cases of anemia, abnormal heart sounds may be detected during a physical examination.
- Enlarged Spleen: Anemia can cause the spleen to work harder to remove old or damaged red blood cells, leading to enlargement.
- Fainting Spells: In extreme cases, low oxygen levels in the blood can cause fainting or loss of consciousness.
- Delayed Growth in Children: Chronic anemia can impair growth and development in young children.
- Depression or Anxiety: Anemia can affect mood and overall sense of well-being, leading to symptoms of depression or anxiety.
- Impaired Immune Function: Low levels of red blood cells can weaken the immune system, making individuals more susceptible to infections.
Diagnostic Tests:
- Complete Blood Count (CBC): This test measures the levels of various blood components, including red blood cells, white blood cells, and platelets, to assess for anemia.
- Peripheral Blood Smear: A sample of blood is examined under a microscope to evaluate the size, shape, and number of red blood cells, which can provide clues about the type of anemia.

- Stool Test for Occult Blood: Detects hidden blood in the stool, which can indicate gastrointestinal bleeding as a cause of anemia.
- Hemoglobin Electrophoresis: Identifies abnormal hemoglobin variants that may contribute to certain types of anemia, such as sickle cell disease or thalassemia.
- Reticulocyte Count: Measures the number of immature red blood cells (reticulocytes) in the blood, which can indicate the bone marrow’s response to anemia.
- Echocardiogram: Ultrasound of the heart to assess its structure and function, particularly useful in severe cases of anemia to evaluate for cardiac complications.
- Oxygen Saturation: Measures the percentage of hemoglobin saturated with oxygen in the blood, providing information about oxygen delivery to tissues.
- Coagulation Studies: Assess blood clotting function, particularly important if anemia is associated with bleeding disorders or clotting abnormalities.
- Colonoscopy: Endoscopic examination of the colon to evaluate for sources of gastrointestinal bleeding that may cause anemia.
Treatments:
- Iron Supplementation: Oral or intravenous iron supplements may be prescribed to correct iron deficiency and improve red blood cell production.
- Vitamin B6 Supplementation: If vitamin B6 deficiency is identified as a cause of sideroblastic anemia, supplements may be recommended to address the deficiency.
