Abstract L-asparaginase is an effective antileukaemic drug and a potent inhibitor of hepatic protein synthesis. Its effect on lipid metabolism was studied in two cohorts of children with ALL, one of whom received L-asparaginase concomitantly with three other drugs (protocol BFM 79). In the second protocol (BFM 83) administration of L-asparaginase was arranged to follow the other three drugs in time sequence. The two major findings of this study were elevated serum levels of total cholesterol and a strong increase in serum triglycerides. The former change was due to an increase in α-cholesterol and could not be attributed to L-asparaginase because it was also found following protocol BFM 83 before the administration of the drug. Elevations of total triglycerides were due to high levels of exogenous chylomicron bound triglycerides and were limited in occurrence almost exclusively to the period of L-asparaginase monotherapy. Hypothyroidism was excluded as a possible pathogenetic mechanism. These changes in lipid metabolism induced by L-asparaginase during intensive remission induction chemotherapy are fully reversible.
