A patient with long standing seropositive rheumatoid arthritis developed lymphocytosis which phenotypically involved the cytotoxic/suppressor T-lymphocyte population. There are 10 reported instances of this new disease entity described as "chronic T-cell lymphocytosis with neutropenia" or "chronic suppressor T-cell lymphocytic leukemia." The disease is characterized by hepatosplenomegaly, neutropenia, and the frequent presence of rheumatoid factor without clinical evidence of rheumatoid arthritis. Splenectomy in our patient, as well as in other instances where undertaken, has been ineffective in alleviating the neutropenia. The peripheral blood lymphocytes in our patient were OKT-3+, OKT-5+, OKT-8+, OKT-11+, cALL-, OKT-6-, TdT-. They possessed ADCC but no NK activity and did not suppress PWM-induced B-cell differentiation in spite of the presence of Fc receptor for IgG. Since the lymphocytosis of OKT-8+ cells appears to be clonal, it is suggested that the disease be designated chronic suppressor T-cell lymphocytic leukemia.

UI MeSH Term Description Entries
D007945 Leukemia, Lymphoid Leukemia associated with HYPERPLASIA of the lymphoid tissues and increased numbers of circulating malignant LYMPHOCYTES and lymphoblasts. Leukemia, Lymphocytic,Lymphocytic Leukemia,Lymphoid Leukemia,Leukemias, Lymphocytic,Leukemias, Lymphoid,Lymphocytic Leukemias,Lymphoid Leukemias
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION. Blast Transformation,Blastogenesis,Lymphoblast Transformation,Lymphocyte Stimulation,Lymphocyte Transformation,Transformation, Blast,Transformation, Lymphoblast,Transformation, Lymphocyte,Activation, Lymphocyte,Stimulation, Lymphocyte
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009503 Neutropenia A decrease in the number of NEUTROPHILS found in the blood. Neutropenias
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000911 Antibodies, Monoclonal Antibodies produced by a single clone of cells. Monoclonal Antibodies,Monoclonal Antibody,Antibody, Monoclonal
D000920 Antibody-Dependent Cell Cytotoxicity The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent. ADCC,Cytotoxicity, Antibody-Dependent Cell,Cell Cytoxicity, Antibody-Dependent,Antibody Dependent Cell Cytotoxicity,Antibody-Dependent Cell Cytotoxicities,Antibody-Dependent Cell Cytoxicities,Antibody-Dependent Cell Cytoxicity,Cell Cytotoxicities, Antibody-Dependent,Cell Cytotoxicity, Antibody-Dependent,Cell Cytoxicities, Antibody-Dependent,Cell Cytoxicity, Antibody Dependent,Cytotoxicities, Antibody-Dependent Cell,Cytotoxicity, Antibody Dependent Cell,Cytoxicities, Antibody-Dependent Cell,Cytoxicity, Antibody-Dependent Cell
