Hematopoietic cell damages due to infection drugs, radiation, etc can cause which anemia?

• A. Diminished erythropoiesis anemia
• B. Aplastic anemia
• C. Hemolytic anemia
• D. Megaloblastic anemia

Answer: (A)

Insults to hematopoietic cells from infection, drugs, or radiation suppress the bone marrow’s ability to produce blood cells, leading to aplastic anemia. This condition features pancytopenia with a hypocellular marrow (often fatty replacement) due to loss of hematopoietic stem cells, so erythropoiesis diminishes along with leukopoiesis and thrombopoiesis. Hemolytic anemia results from increased red cell destruction, while megaloblastic anemia stems from defective DNA synthesis in erythroid precursors (folate/B12 deficiency). The situation described best fits aplastic anemia, where production is suppressed rather than destruction or maturation defects.
