摘要
High plasma levels of the omega-3 fatty acids eicosapentaenoic acid (EPA), docosahexaenoic acid, and docosapentaenoic acid associates with positive outcomes in adult renal transplant recipients. However, data from pediatric populations are scarce. The aim of the study was to assess the fatty acid profile in a pediatric renal transplantation cohort and to examine the associations between plasma omega-3 fatty acids and cardiovascular disease (CVD) risk factors.In this cross-sectional study comprising 53 children (median age, 12.2 years; 32 boys) with a renal transplant, we assessed the prevalence of CVD risk factors as well as markers of end organ damage: carotid intima-media thickness (cIMT) and left ventricular mass index. The associations between plasma omega-3 fatty acids and CVD risk factors were assessed.Twenty-five (47%) patients were preemptively transplanted. Seventy-six percent had dyslipidemia and 51% had hypertension. The mean left ventricular mass index was 40.4 ± 14.3 g/m2.7, and 14% had left ventricular hypertrophy. The mean cIMT was 0.41 ± 0.04 mm. In a multivariate linear regression, EPA levels were inversely associated to blood pressure (β coeff. = -0.37, P = .007), triglycerides (β coeff. = -0.44, P = .01), and high-density lipoprotein cholesterol (β coeff. = -0.41, P = .01).EPA levels are inversely associated with components of the metabolic syndrome, which may provide support for specific dietary advice or supplementation in this patient population. cIMT is less pronounced in our cohort than in comparable cohorts with lower rate of preemptive transplantations. Our results need replication in prospective cohorts.
