Flow cytometric determination of RBC survival in autoimmune hemolytic anemia

Transfusion

Abstract

In cases of warm autoimmune hemolytic anemia (WAIHA), crossmatch incompatible RBCs are most often used for transfusion. The determination of the in vivo survival of transfused and autologous RBCs in WAIHA is helpful in the assessment of the efficacy of transfusion and other therapeutic interventions. A 38-year-old man presented with acute WAIHA, thrombocytopenia, and neutropenia. Steroids and IVIG therapy were ineffective, and the patient received RBCS: Because of increasing hemolysis and persisting thrombocytopenia, splenectomy was performed, resulting in partial remission. Further improvement was achieved by immunosuppressive therapy. Survival of transfused and autologous RBCs was determined, using a flow cytometric method based on the determination of different blood group antigens of patient and donor RBCS: The survival of autologous and transfused RBCs before splenectomy was determined on two consecutive days. The life span of autologous RBCs remained rather stable at 69 and 64 hours on Days 10 and 11, respectively, whereas the life span of transfused RBCs decreased from 186 hours to 25 hours. After splenectomy, the life span of transfused RBCs almost normalized: 43 days at postsplenectomy Day 3 and 87 days at postsplenect...Continue Reading

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.
