Summary:To obtain further insight into the role of selenium in the development of atherosclerosis, plasma selenium and lipid parameters were determined in 126 Portuguese subjects living in the region of Lisbon, 60 women and 66 men, 20-60 years old, divided up in to three groups according to their plasma lipid profile: Group I consisted of normolipidemic subjects having plasma triglycerides and total cholesterol < 200mg/dL; Group II was composed of hypercholesteremic subjects with total cholesterol > 200mg/dL and plasma triglycerides < 200mg/dL; Group III was composed of hypercholesteremic and hypertriglyceremic subjects having total cholesterol and plasma triglycerides > 200mg/dL. Respective values for mean plasma selenium (+/- SD) in the groups were: 93 +/- 18 micrograms/L, 90 +/- 17 micrograms/L and 96 +/- 18 micrograms/L. A weak significant difference in plasma selenium between women and men was, however, observed in Group I (87 +/- 20 micrograms/L vs. 100 +/- 11 micrograms/L, p < 0.05). Regression analysis showed no significant relationship between plasma selenium and lipid parameters, except in the most hyperlipidemic women of Group III, where a weak correlation between plasma selenium and the HDL-cholesterol/total cholesterol ratio (r = 0.80, p < 0.05) was observed. The present study suggests that the relationship between selenium and HDL-cholesterol has to be further examined, taking into account nutritional, metabolic and genetic factors.
