Dyslipidemia in nonalcoholic fatty liver disease

Purpose of review To summarize recent findings regarding the characterization of lipoprotein disturbances in nonalcoholic fatty liver disease (NAFLD) and their relationship with cardiovascular disease (CVD) and make recommendations for the management of this situation. Recent findings Advanced lipoprotein profile (using NMR spectroscopy) has shown profound lipoprotein derangements which are overlooked with conventional analyses: increased number and size of very low-density lipoproteins particles, increased number of low-density lipoprotein particles (especially small sized), smaller high-density lipoprotein particles, and an increase in the triglyceride content of all these lipoproteins. Other changes such as impaired functionality of high-density lipoprotein particles have also been observed. Beyond low-density lipoprotein-related parameters, the importance of triglyceride-rich lipoproteins in the pathogenesis of atherosclerosis has recently gained interest. Several studies suggest that these lipoproteins may have an independent role in CVD in NAFLD populations. Although outcome studies with lipid-lowering drugs in NAFLD are lacking, treatment with both statins, and especially, triglyceride-lowering drugs could be promising for these populations at high residual cardiovascular risk. Summary In addition to being the main determinant of dyslipidemia, disturbances in triglyceride-rich lipoproteins are thought to be the key factor of increased CVD risk in NAFLD. Treatme...
