Direct Measurement of Leukemic Cell Turnover (Synthesis and Removal) in Patients With Chronic Lymphocytic Leukemia (CLL) Using Deuterated Water

Summary

Chronic lymphocytic leukemia. B-cell chronic lymphocytic leukemia (B-CLL) is the most prevalent leukemia in the Western Hemisphere, accounting for ~25% of all leukemia's. It represents a monoclonal expansion of small, long-lived, apparently slowly dividing CD5+ B cells. Because of the low proliferative index and a presumed uniform proliferative rate of B-CLL cells in vivo (a fact not yet tested or documented), B-CLL appears to be primarily a disease of accumulation rather than proliferation.

Description

Chronic lymphocytic leukemia. B-cell chronic lymphocytic leukemia (B-CLL) is the most prevalent leukemia in the Western Hemisphere, accounting for ~25% of all leukemia's. It represents a monoclonal expansion of small, long-lived, apparently slowly dividing CD5+ B cells. Because of the low proliferative index and a presumed uniform proliferative rate of B-CLL cells in vivo (a fact not yet tested or documented), B-CLL appears to be primarily a disease of accumulation rather than proliferation.

B-CLL remains an incurable illness and there is no survival benefit to early intervention.

Therefore, patients with early stage disease are usually followed closely without initiating treatment. Patients with more extensive disease or progressive cytopenias are eventually treated with cytotoxic agents, with or without prednisone, or with nucleoside analogues that promote apoptosis in the leukemic cells. The clinical outcome of the disease is determined both by the profound dysregulation of the immune system that results in infection and autoimmunity and by leukemic infiltration and destruction of organs. Autoimmune phenomena are common and frequently directed against hematopoietic cells, resulting in autoimmune hemolytic anemia (10-25%) or immune thrombocytopenia.

Medical and Biotech [MESH] Definitions

A chronic leukemia characterized by abnormal B-lymphocytes and often generalized lymphadenopathy. In patients presenting predominately with blood and bone marrow involvement it is called chronic lymphocytic leukemia (CLL); in those predominately with enlarged lymph nodes it is called small lymphocytic lymphoma. These terms represent spectrums of the same disease.

A chronic leukemia characterized by a large number of circulating prolymphocytes. It can arise spontaneously or as a consequence of transformation of CHRONIC LYMPHOCYTIC LEUKEMIA.

A lymphoid leukemia characterized by a profound LYMPHOCYTOSIS with or without LYMPHADENOPATHY, hepatosplenomegaly, frequently rapid progression, and short survival. It was formerly called T-cell chronic lymphocytic leukemia.

A pathologic change in leukemia in which leukemic cells permeate various organs at any stage of the disease. All types of leukemia show various degrees of infiltration, depending upon the type of leukemia. The degree of infiltration may vary from site to site. The liver and spleen are common sites of infiltration, the greatest appearing in myelocytic leukemia, but infiltration is seen also in the granulocytic and lymphocytic types. The kidney is also a common site and of the gastrointestinal system, the stomach and ileum are commonly involved. In lymphocytic leukemia the skin is often infiltrated. The central nervous system too is a common site.

A basic helix-loop-helix transcription factor that plays a critical role in HEMATOPOIESIS and as a positive regulator in the differentiation of ERYTHROID CELLS. Chromosome translocations involving the TAL-1 gene are associated with T-CELL ACUTE LYMPHOCYTIC LEUKEMIA.
