Therapeutic leukapheresis

For the majority of leukemic patients, leukapheresis represents emergency treatment aimed at reducing the number of white blood cells and producing an immediate improvement in the clinical picture. We have shown that leukapheresis procedures performed for the therapy of leukocytosis in 4 patients with acute leukemia (2 myelocytic; 1 lymphocytic; 1 monoblastic) resulted in marked reduction in the white blood cell count and a considerable reduction in symptomatology. Repeat removal of white blood cells applied in 20 instances for patients with chronic myelocytic leukemia also produced a significant decrease in the cell count and relief of symptoms such as sweating, malaise, and pain due to splenomegaly. In chronic lymphocytic leukemia (31 patients), intensive and frequent leukapheresis procedures were followed by a marked fall in white blood cell count, regression of splenomegaly/lymphadenopathy and resolution of many symptoms and signs induced by the large number of cells.
