摘要: A patient with Chronic Lymphocytic Leukemia (CLL) characterized by an expansion of helper phenotype mature T lymphocytes is here described. The these cells was OKT3+, OKT4+, Leu 9+, 5/9+, OKT8−, Tac− and functional studies showed a strong activity on B cell differentiation; “in vivo” presence IgG-lambda paraproteinaemia has been demonstrated. Cytogenetic multiple clonal, numerical structural rearrangements which included tandem t (14; 14) (q11; 32) translocation. Hybridization HTLV I related specific bands indicating the exogenous sequences to prototype virus but derived from different Retrovirus (HTLV 1c). clinical course aggressive unsuccessful treatments various polichemotherapeutic protocols, associated leukaphereses, were performed. authors underline that despite morphological, immunological, biological virological heterogeneity, common feature T-helper CLL inexorable needs new therapeutic approach.
