Summary

Lipoprotein(a) [Lp(a)] is one of the most atherogenic lipoproteins and consists of a glycoprotein called apo(a) which is covalently linked to an LDL particle. Lp(a) is mostly synthesized in the liver and metabolized both via the kidney and liver. A size polymorphism of apo(a) (high and low molecular weight isoforms) exists that negatively correlates with plasma Lp(a) levels. We could previously show that fragments of apo(a) are secreted into the urine and the daily secretion rate correlates with plasma Lp(a) concentrations. Nicotinic acid (NA) and extended release nicotinic acid (ERN) are currently the only lipid lowering drugs that consistently reduce plasma Lp(a) by up to 30%. Since the mechanism by which ERN lowers Lp(a) is not entirely clear we aim to investigate this mechanism in vivo and in vitro.

Plain Language Summary

Simplified for easier understanding

This study tests whether extended-release nicotinic acid (a form of vitamin B3) can lower elevated levels of lipoprotein(a), a type of cholesterol linked to heart disease risk. It is open to men and women aged 18 to 75 who already have high lipoprotein(a) and are taking cholesterol-lowering medication. Pregnant women and children are not eligible.
