Summary: | Hyperhomocysteinaemia is considered as an important independent risk factor for atherosclerosis and thrombotic disease. This study determined the distribution of homocysteine (Hcy) levels in healthy Tunisian subjects and evaluated the relationship between Hcy levels and some cardiovascular risk factors. Randomly selected subjects (592 men and 114 women) were recruited from different regions of Tunisia. The overall mean Hcy level was 12.6 (SD 5.4) [micro]mol/L. Hcy levels in subjects with hyperhomocysteinaemia varied according to geographical region. Subjects with hyperhomocysteinaemia had significantly elevated total cholesterol, LDL cholesterol, apolipoprotein A and apolipoprotein B and lower vitamin [B.sub.12] levels compared with subjects with normohomocysteinaemia. Hcy levels correlated with total cholesterol (r = 0.09), apolipoprotein A (r = 0.012), and B (r = 0.013) levels and total/HDL cholesterol ratio (r = -0.085). Further epidemiological studies are needed to determine the precise role of Hcy in cardiovascular disease. L'hyperhomocysteinemie est consideree comme un important facteur de risque independant pour l'atherosclerose et la maladie thrombotique. La presente etude a determine la repartition des taux d'homocysteine chez des sujets tunisiens en bonne sante et a evalue la relation entre ce taux et certains facteurs de risque cardio-vasculaires. Des sujets ont ete selectionnes aleatoirement (592 hommes et 114 femmes) a partir de plusieurs regions de Tunisie. Le taux moyen d'homocysteine etait de 12,6 [imol/l (E.T. 5,4). Le taux d'homocysteine chez les sujets atteints d'hyperhomocysteinemie variait en fonction de leur region geographique. Les sujets atteints d'hyperhomocysteinemie presentaient des taux de cholesterol total, de cholesterol des lipoproteines de basse densite, d'apolipoproteine A et d'apolipoproteine B tres eleves ainsi que des taux moindres de vitamine [B.sub.12] par rapport aux sujets ayant un taux normal. Les taux d'homocysteine etaient correles aux taux de cholesterol total (r = 0,09), d'apolipoproteine A (r = 0,012) et d'apolipoproteine B (r = 0,013) ainsi qu'au rapport entre le cholesterol total et le cholesterol des lipoproteines de basse densite (r = -0,085). Des etudes epidemiologiques supplementaires sont necessaires pour determiner le role precis de l'homocysteine dans les maladies cardio-vasculaires. |
