[Serum lipids and lipoproteins in a population from Oran. Comparison with a population from Lille]

Lipids, lipoproteins and apolipoproteins were analyzed in plasma of a city living Algerian population (Oran) free of obvious pathology. 129 individuals of this population were compared to a sample of subjects living in the surroundings of Lille (France). Several parameters were significantly different between the two populations. Cholesterol and phospholipids were lower in the population of Oran when compared with the population of Lille (4.90 mmol/l versus 5.47 mmol/l; 2.73 mmol/l versus 3.22 mmol/l respectively). Lipoproteins LpAI and LpAI:All were also lower in the population of Oran in comparison with the population of Lille (0.38 g/l versus 0.52 g/l; 0.68 g/l versus 1.00 g/l respectively), while LpCIII:B, LpE:B and Lp(a) were higher in the population of Oran when compared with the population of Lille (0.09 g/l versus 0.06 g/l; 0.28 g/l versus 0.16 g/l; 0.1 g/l versus 0.048 g/l) respectively. Several results argue in favor of the use of these lipoprotein parameters to better define the atherosclerotic risk. This was the main reason for characterizing the lipoprotein profile of such a population with a still unknown cardiovascular disease incidence.
