Microcytic anemia
Mnemonic TAILS:[1]
- Thalassemia.
- Anemia of chronic diesease.
- Iron deficiency anemia.
- Lead toxicity.
- Sideroblastic anemia.
Macrocytic anemia
Mnemonic Few Big RBCs May Lead To Palor:
- Folate deficiency.
- Vitamin B12 deficiency.
- Rx.
- Myelodysplastic syndromes.
- Liver disease (cirrhosis).
- Thyroid disease (hypothyroidism).
- Post-splenectomy.
Specific types of anemia
Pernicious anemia
General
- Macrocytic anemia.
Etiology:
- Autoimmune - leads to loss of parietal cells.
- Parietal cells produce intrinsic factor (important for vitamin B12 absorption) and hydrogen chloride.
Diagnosis - serology for antibodies to:[2]
- Parietal cell.
- Iintrinsic factor.
Microscopic
Features:
- Loss of parietal cells.
