[Lipid, lipoproteins and atherogenesis profiles in sickle cell disease among Central African patients]. / Évaluation du profil lipoprotéique et du risque athérogène chez les drépanocytaires homozygotes et hétérozygotes de Brazzaville.

ABSTRACT

Lipid and lipopproteins disorders are well established in sera from sickle cell disease (SCD) patients out of Central Africa. The present case-control study was conducted to compare serum levels of total cholesterol (TC), HDL-C, triglycerides (TG), LDL-C and TC/HDL-C ratio (atherogenic index) from SCD homozygotes (SS) in steady state, SCD heterozygotes (AS) and controls (AA) in Brazzaville, Congo. Significant reductions of TC and LDL-C vs. increase in TG were reported in SS. However, significant decrease in HDL-C and increase in atherogenic index were observed in AS. We recommend prevention of oxidative stress, dyslipidemia and atherosclerosis in SCD using hygiene-diet measures. Only longitudinal studies in large populations will provide pathophysiological basis of lipid and lipoproteins disorders in SCD.
