Abstract
Objective: Familial hypercholesterolemia (FH) is characterized by elevated levels of low-density lipoprotein cholesterol (LDL-C) and cardiovascular disease (CVD). Although the role of LDL-C in FH has been studied, the contribution of high-density lipoproteins (HDL) to CVD in FH remains unknown. This study aimed at highlighting the role of HDL in FH.
Methods: HDL-specific phospholipid efflux (HDL-SPE) assay was developed to predict CVD risk. HDL-SPE was examined in FH patients (n=30) and compared with age- and sex-matched non-FH controls (n=60).
Results: FH patients had significantly lower HDL-SPE levels (0.90±0.12) than controls (1.12±0.10; p<0.05), despite similar HDL-cholesterol levels in both groups (FH: 57.9±18.7 mg/dl; controls: 57.1±13.8 mg/dl). These differences remained significant after adjusting for confounders.
Conclusions: These findings suggest there may be dysfunctionality of HDL in FH.
