The thrombocyte count, the factor XIII (F XIII) activity, the concentration of fibrinogen (F I), prothrombin (F II), fibronectin (CIG), albumin and the proteinase inhibitors antithrombin III (AT III), alpha 2-macroglobulin (A2M), alpha 1-antitrypsin (A1A) and Cl-esterase inactivator (Cl-INA) were determined in ten children with acute lymphoblastic leukaemia (ALL). Changes due to the disease and to therapy were observed. Before the start of treatment the patients had thrombocytopenia secondary to the disease, and the proteinase inhibitors--especially Cl-INA and A1A--were raised. During the induction phase the thrombocyte count rose but there was also a marked increase in the concentration of…
