Effect of alcohol on serum lipids & lipoproteins in male drinkers

The evaluation of the effect of moderate and high doses of ethanol on the serum levels of triglyceride (TG), total cholesterol (TC), cholesterol content of very low density lipoprotein (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL), HDL2, HDL3 subfractions and apoproteins: apo-AI and apo-B was undertaken in 45 (25 controls, 10 moderate and 10 high dose drinkers) healthy males. The results of this preliminary study showed a significant rise in total HDL-cholesterol and apo-AI levels of alcoholics of both the groups. Out of the two subfractions, HDL2 appeared to be induced more. Increased levels of atherogenic lipids (TG, VLDL-chol., LDL-chol. and apo-B) were found in high as well as moderate drinkers. Our results suggest that the benefit of alcohol intake need to be weighed carefully against its considerable risks.
