Dyslipidaemia is often associated with adult growth hormone (GH) deficiency. Reduced removal of very-low-density lipoprotein (VLDL) apolipoprotein B-100 (apo B-100) can, in part, explain the "unfavourable" lipid profile of these patients. By modifying VLDL composition and through its action on low-density lipoprotein (LDL) receptors, GH may improve the lipid profile by increasing direct hepatic uptake of VLDL apo B-100, thereby decreasing conversion to LDL. Although GH stimulates VLDL apo B-100 secretion, this is exceeded by its effects in upregulating LDL receptors and modifying VLDL composition. We hypothesize that the improved lipid profile, in particular the decrease in cholesterol-rich VLDL particles, may contribute to a possible antiatherogenic action of GH. GH appears to have an important role in hepatic apo B-100 metabolism. However, we are just at the beginning of understanding the underlying mechanism. Further studies are required to investigate the effect of GH on other lipoprotein classes, in particular VLDL subfractions, intermediate-density lipoprotein, LDL and high-density lipoprotein. The key question, however, remains as to whether GH replacement therapy can reduce cardiovascular mortality. Long-term studies with sufficient numbers of patients are required to answer this question.
