Study Notes
- Iron deficiency anemia: characterized by decreased iron levels in the body, leading to a need for supplementation with ferrous sulfate or ferrous fumate. Side effects may include gastrointestinal symptoms and dark stools. Copper and vitamin C are essential for iron absorption. Oral iron dose is typically 325 mg three times a day, providing 65 mg of elemental iron per dose. Deferoxamine is an antidote for iron overdose, acting through a non-receptor mechanism of binding to free iron. Parenteral iron is restricted due to black box warning of anaphylactic shock. The body stores iron as hemosiderin and ferritin.
- Normocytic anemia: caused by decreased erythropoietin (EPO) production, leading to a need for erythropoiesis-stimulating agents such as epoetin alfa, epoetin beta, and darbepoetin.
- Aplastic anemia: characterized by bone marrow failure to produce red blood cells. Treatment options include immunosuppressants, blood transfusions, and bone marrow transplantation.
- Hemolytic anemia: characterized by destroyed and removed red blood cells before their lifespan. No specific mention of causes or treatments in the text.
- Erythropoiesis: the process of producing red blood cells in the body. Erythropoiesis-stimulating agents (ESAs) are used to stimulate this process in anemia.
