Moreover, since suspicion of autoimmune hemolytic anemia (AIHA) was raised, she was empirically started on emergency methylprednisone treatment, in accordance with evidence that glucocorticoids not only abrogate immune‐mediated hemolysis but also have direct actions to enhance erythroid progenitor proliferation and erythropoietin production, thereby increasing erythropoiesis [10]. This evidence concerns the gene EPO and autoimmune hemolytic anemia.
