Chronic lymphocytic leukemia and hairy-cell leukemia

Abstract:
The chronic lymphoid leukemias are a heterogeneous group of disorders with different immunologic, biologic, and clinical features. The most common of these are the B-cell diseases, chronic lymphocytic leukemia and its variants, including prolymphocytic leukemia and hairy cell leukemia. The increased use of immunophenotyping has identified a number of other less common but related disorders. Despite being clonal disorders, the chronic B-cell leukemias exhibit immunologic abnormalities in multiple other lineages, the mechanism for which is not clear. Fludarabine, 2'-deoxycoformycin, and 2-chlorodeoxyadenosine are purine analogues that have advanced the treatment of chronic B-cell leukemias. Fludarabine appears to be the single most effective agent for chronic lymphocytic leukemia, while 2'-deoxycoformycin and 2-chlorodeoxyadenosine are both extremely effective in hairy cell leukemia. A recently completed comparison of alpha-interferon with 2'-deoxycoformycin in hairy cell leukemia may redefine the standard therapy for this disorder. Continued interaction between laboratory and clinical scientists is essential for continued progress in these diseases.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
