title: A rapid increase in lipoprotein (a) levels after ethanol withdrawal in alcoholic men.
abstract: Plasma concentrations of lipoprotein (a) (Lp(a)) were studied in 11 male alcoholics at the end of a drinking period and monitored during subsequent abstinence. Lp(a) levels showed a daily increase for four consecutive days after the beginning of abstinence, the values for the third and the fourth day being significantly higher than those of the first day (p less than 0.05 and p less than 0.01, respectively). The changes in Lp(a) showed no association with the changes in low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol levels. In one alcoholic subject with a heterozygous form of familial hypercholesterolemia who was monitored for 11 days, the Lp(a) levels rose up to the fourth day and remained at a high level thereafter. These results suggest that ethanol ingestion may be associated with a lowering of Lp(a) levels, which may contribute to the delayed progression of atherosclerosis observed in alcohol drinkers. Ethanol intake may be added to the short list of factors that affect the quite stable, genetically determined Lp(a) concentrations in the plasma.
