Abstract
BACKGROUND
The interest in cystic fibrosis (CF) dyslipidaemia as a potential risk factor for cardiovascular disease is increasing with patients' survival. This study aimed to investigate CF dyslipidaemia, its clinical correlates and links to oxidized low-density lipoprotein (oxLDL), adiponectin, and apolipoprotein E (APOE).
METHODS
This cross-sectional study assessed clinical characteristics of CF, as well as the serum lipid profile, oxLDL, adiponectin, and APOE.
RESULTS
In total, 108 CF subjects were enrolled in this study, with a median age of 22 years, BMI of 20.5 kg/m2, FEV1% of 61%, of which 81% were pancreatic insufficient (PI). Healthy subjects (HS; n = 51) were in similar age. Hypocholesterolaemia occurred in 31% of CF subjects and in no HS. Hypertriglyceridaemia concerned 21% of patients (HS: 8%, p = .04), and low HDL-C 45% (HS: 6%, p < .0001). At least one of these three CF dyslipidaemia disturbances was present in 62% of CF subjects, but there were no significant differences in oxLDL, oxLDL/LDL-C ratio, adiponectin, and APOE between CF and HS groups. PI was independently associated with low total cholesterol, LDL-C, and non-high density lipoprotein cholesterol, with age and sex also modifying lipid levels. In CF (n = 42), triglycerides did not correlate with serum tumour necrosis factor α (TNF-α).
CONCLUSIONS
CF dyslipidaemia is highly prevalent and heterogenous. The lipid profile weakly associates with the clinical characteristics of CF as well as oxLDL, adiponectin, and APOE. Further research is needed, especially regarding HDL function in CF, the causes of hypertriglyceridaemia, and the value of essential fatty acid supplementation for CF dyslipidaemia.
