Study Notes
- Extrinsic hemolytic anemias include autoimmune, drug-induced, microangiopathic, and macroangiopathic types.
- Warm AIHA is a chronic anemia caused by IgG, while cold AIHA is an acute anemia caused by IgM and complement.
- Spherocytes and agglutinated RBCs are seen in warm AIHA, while schistocytes are seen in microangiopathic and macroangiopathic hemolytic anemias.
- Hemolytic anemia can also be caused by infection, such as malaria and Babesia.
- Neutropenia is characterized by an absolute neutrophil count < 1500 cells/mm3 and can be caused by sepsis, drugs, and autoimmune disorders.
- Lymphopenia is characterized by an absolute lymphocyte count < 1500 cells/mm3 and can be caused by HIV, radiation, and sepsis.
- Eosinopenia is characterized by an absolute eosinophil count < 30 cells/mm3 and can be caused by Cushing syndrome and glucocorticoids.
- Glucocorticoids can cause neutrophilia despite causing lymphopenia and eosinopenia.
- Warm AIHA can be treated with steroids, rituximab, and splenectomy, while cold AIHA can be treated with cold avoidance and rituximab.
- Microangiopathic hemolytic anemia can be seen in DIC, TTP/HUS, SLE, HELLP syndrome, and hypertensive emergency.
