Abstract

A 60-year-old man was admitted to our hospital with severe anemia and blood findings showed hemolytic anemia. Further serological examination revealed both warm-reactive autoantibody and cold agglutinin against erythrocytes. The cold agglutinin showed a low titer, 1 : 32 at 4 degrees C, and had a high thermal amplitude of 30 degrees C or higher, resulting in sufficient activity for hemolysis. Since no underlying disorders could be detected, the diagnosis was idiopathic mixed-type autoimmune hemolytic anemia. Although thrombocytopenia (Evans syndrome) subsequently appeared, corticosteroid was extremely effective for both anemia and thrombocytopenia. In this report we describe a rare case of Evans syndrome associated with mixed-type autoimmune hemolytic anemia, which had a dramatic response to corticosteroid therapy.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in the circulation. Discover the latest research on AIHA here.
