Abstract

The migration inhibiting factor (MIF) test was performed on 27 patients with chronic neutropenia using acute myeloblastic leukemia (AML) blasts and normal lymphocytes as antigens. Eight patients reacted positively to AML blasts, and the natural history of their disease differed from that of the remaining neutropenic patients: two of the eight patients developed AML and one showed evidence of preleukemic changes. Recurrent severe infections were common and one patient in this group developed systemic lupus erythematosus. The MIF test toward AML blasts may be regarded as a warning sign of a preleukemic state among neutropenic patients.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
