FCHL (familial combined hyperlipidaemia) is the most frequent inherited disorder of lipid metabolism leading to premature atherosclerosis. The usual phenotype in FCHL is elevated fasting plasma triacylglycerols, low HDL (high-density lipoprotein)-cholesterol concentrations and elevated plasma apolipoprotein B concentrations. The metabolic basis for this phenotype is hepatic overproduction of VLDL (very-low-density lipoprotein), which is only partly linked to the insulin resistance associated with FCHL. At this stage the molecular basis for this VLDL overproduction is not known, but emerging evidence points to a disturbed trapping of peripheral fatty acids, resulting in enhanced hepatic flux of NEFA [non-esterified ('free') fatty acids]. Postprandial hyperlipidaemia with accumulation of lipoprotein remnants and NEFA have been implicated in the development of atherosclerosis in this disorder. It has been proposed that, by VLDL overproduction, fasting hypertriglyceridaemia may lead to 'overflow' of the catabolic cascade for triacylglycerol-rich particles, thereby explaining the delayed catabolism of remnants in FCHL. Delayed clearance of remnants of VLDL and chylomicrons leads to enhanced interaction of these highly atherogenic particles with the endothelium, and enhanced trans-endothelial migration of the particles, resulting in a chronic inflammatory response that is the initiation of the atherosclerotic lesion. In this process, activated leucocytes (either directly by the remnants or indirectly by released NEFA) play an important role by adherence to the endothelium and migration into the subendothelial space, where the uptake of atherogenic remnants results in a vicious cycle of activation of endothelium, leucocytes and production of cytokines.
