We aimed to evaluate the levels of high-sensitivity C-reactive protein (hs-CRP) and proinflammatory cytokines, which are known to be associated with atherogenesis, in patients with this condition. Method and results — A total of 10 patients with homozygous FH (5 women and 5 men, mean age 17.0 ± 6.9 years, body mass index (BMI) (18.8 ± 1.9 kg/m2) and 16 healthy controls were included. hs-CRP levels, proinflammatory cytokine levels and lipid parameters were measured and compared between patients and control subjects. Homozygous FH patients had significantly higher total cholesterol, LDL-cholesterol and Lp(a) levels and significantly lower triglyceride and HDL cholesterol levels, compared to controls (P = 0.0001, for all). Serum hs-CRP (3.7 ± 1.3 mg/L vs. 0.6 ± 0.6 mg/L) and IL-1β, IL-2R, IL-6, IL-8, IL-10, TNF-α levels were all significantly higher in the homozygous FH group, compared to controls (P = 0.0001, for all). Conclusions — Homozygous FH patients have significantly higher levels of hs-CRP and circulating proinflammatory cytokines, which may explain their increased risk of atherosclerotic disease. hs-CRP is an important biomarker that may be helpful in the identification of asymptomatic CHD in FH patients. |
