Abstrakt: We found that the distribution of the lipophilic chemotherapeutic agent o,p'-DDD (mitotane) among serum (lipo)proteins was altered in hypertriglyceridemia, with relatively more o,p'-DDD accumulating in the chylomicron and very-low-density lipoprotein (VLDL) fraction. Intralipid, an artificial chylomicron emulsion, or isolated VLDL could extract o,p'-DDD from the other serum (lipo)proteins. There was an inverse relationship between the relative amount of o,p'-DDD found in the fraction exhibiting a density of less than 1.006 g/ml (chylomicrons plus VLDL) and the relative amount observed in the LDL or HDL fractions of serum. Our results indicate that hypertriglyceridemia may impede the entry of o,p'-DDD into the brain or the adrenals. For therapeutic monitoring of o,p'-DDD levels in severe hypertriglyceridemia, we recommend that the chylomicron and VLDL fraction first be removed from the serum by ultracentrifugation.
