| Abstract | HDL cholesterol is a prognostic factor for the incidence of cardiovascular events. However, its predictive power is lost in conditions in which the HDL composition is altered without changing the cholesterol content of the particle (e.g. chronic inflammatory conditions, apoA-I Milano or the cholesterol ester transfer protein deficiency ). Based on that, there is a need for clinical tests that measure the HDL function or composition. It has been published methods that measure the capacity of HDL particles to prevent LDL oxidation or to diminish monocyte migration or that assess the lipid and protein composition (sing mass espectrometry). For example, the HDL inflammatory index (an in vitro assay) is a better predictor of the carotid grosor than HDL cholesterol in women with lupus. By using mass espectrometry it has been identified that low HDL cholesterol cases has a lower sphingomyelin content and higher amounts of ethanolamine plasmalogen in their HDL3 particles. These changes have functional implications, since phospolipid composition determines the protein content at the HDL surface. Cases with coronary heart disease have HDL3 enriched with apoCIV, paraoxonase 1, C3 complement, apoAIV, apoE and several proteinases inhibitors. Although the evidence is still preliminary, there are some markers of HDL function that may be useful in the future to provide complementary information to that derived from HDL cholesterol levels. |
