Abstract
The effect of L‐asparaginase (L‐asp) therapy on circulating antithrombin‐III (AT‐III) was monitored in three patients with acute lymphoblastic leukemia. Serial determination for AT‐III by both a functional assay and an immunologic assay demonstrated a rapid decrease in serum AT‐III levels, followed by a protracted recovery beyond the period of L‐asp exposure. One of the three patients developed a reversible venous thrombosis of the arm. The mechanism of the L‐asparaginase effect may be related to peripheral degradation of AT‐III or to inhibition of production.

Eleven patients with leukemia and lymphoma were treated with 14 courses of E. coli L-asparaginase. Abnormalities of the coagulation screening tests and decreased fibrinogen levels were observed in all patients during treatment. Significant depressions of functional (mean 32%) and antigenic (mean 48%
Previous reports have observed a fall in antithrombin III (AT III) concentration in patients receiving L-asparaginase as part of acute lymphatic leukaemia (ALL) induction therapy. The aim of this study was to define any qualitative changes in AT III that might arise during the course of L-asparagina
