title: LDL-apheresis in two patients with extremely elevated lipoprotein (a) levels.
abstract: Hyperlipidemia and elevated lipoprotein (a) [Lp(a)] levels have been linked to the development and progression of premature atherosclerosis. Two male caucasian patients (36 and 42 years old) with heterozygous familial hypercholesterolemia and extremely elevated Lp(a) concentrations, resistant to diet regimen and lipid lowering drugs, were treated with LDL-apheresis for 55 months (liposorber system, Kaneka, Japan) and 15 months (immunoadsorption system, special Lp(a) columns, Lipopak, Pocard, Russia). Lp(a) dropped on average by 50%, total cholesterol by 27%, LDL-cholesterol by 42%, triglycerides by 43% and the fibrinogen concentration by 16%. Prior to treatment, both patients had suffered three myocardial infarctions. Four and six coronary angiographies with two and four percutaneous transluminal angioplasties (PTCA) were necessary. Since the treatment with LDL-apheresis neither myocardial infarctions nor cardiac complaints have been observed, and both patients have reported better performance. Available data suggest that LDL-apheresis may be effective in the treatment of patients with extremely high Lp(a) concentration.
