- Sideroblastic anemia
lead poisoning, see coarse basophilic stippling of red blood cells on peripheral blood smear
* Specific test: Prussian Blue stain of RBC in marrow. Shows ringed sideroblasts.
Occasionally, the anemia is so severe that support with transfusion is required. These patients usually do not respond to
erythropoietintherapy. [cite book |author=Papadakis, Maxine A.; Tierney, Lawrence M.; McPhee, Stephen J. |title=Current Medical Diagnosis & Treatment, 2006 |publisher=McGraw-Hill Medical |location= |year=2005 |pages= |chapter=Sideroblastic Anemia |isbn=0-07-145410-1 |oclc= |doi= |accessdate=] Some cases have been reported that the anemia is reversed or heme level is improved through use of moderate to high doses of pyrodoxine (Vitamin B6.) In severe cases of SBA, bone marrow transplant is also an option with limited information about the success rate. Some cases are listed on MedLine and various other medical sites. In the case of isoniazid-induced sideroblastic anemia, the addition of B6 is sufficient to correct the anemia.
