Abstract

Plasmapheresis (PA) and low-density lipoprotein apheresis (LDL-A) were assessed in five children with homozygous familial hypercholesterolemia (HFH) previously receiving statins. LDL-A required smaller extracorporeal blood volumes. Mean HDL-cholesterol reduction post-procedure was 32% and 60% with LDL-A and PA, respectively. Non-HDL-C reduction was 64% and 69%, respectively. Pre-procedural LDL-C decreased significantly with weekly versus biweekly LDL-A. Carotid intimal media thickness (IMT) studies demonstrated disappearance of atheromatous lesions and normal ITM in 4/5 patients. Echocardiography revealed normal aortic valves, coronary orifices and supra-valvular area in all patients. Apheresis is effective in pediatric HFH. It may be started in patients weighing 14 kg.
