摘要: T cells from allogeneic bone marrow grafts are responsible for a graft versus leukemia effect. Use of recombinant Interleukin-2 (rIL-2) after autologous transplantation (BMT) may enhance immune function and hopefully reproduce the reaction. We report here hematologic immunologic changes observed in first 10 patients phase 1 trial studying infusion IL-2 BMT. All had high-risk malignancies received 6 days constant (Eurocetus, Amsterdam, The Netherlands) at dose 3 x 10(6) Cetus Units/m2/d, 79 +/- 12 Clinical toxicities involving cutaneous, cholestatic, gastrointestinal, hemodynamic effects occurred during treatment but reversed all cases. Completion was 91% scheduled IL-2. Hematologic toxicity moderate transient with no failure. Increases eosinophil lymphocyte counts were significant (P less than .05). Stimulation system intense prolonged, manifested by increase numbers CD3+, CD3+DR+, CD3+ CD25+ lymphocytes, natural killer (NK) (all P .01), Lymphokine-activated killers (LAK) NK activities .01 This study establishes feasibility 6-day administration rIL-2 BMT leading to major activation 2.5 months
