First steps toward the establishment of a German low-density lipoprotein-apheresis registry: recommendations for the indication and for quality management.

New recommendations for the indication of treatment with selective extracorporeal plasma therapy low-density lipoprotein apheresis (LDL-apheresis) in the prevention of coronary heart disease are urgently needed. The following points are the first results of the ongoing discussion process for indications for LDL-apheresis in Germany: all patients with homozygous familial hypercholesterolemia with functional or genetically determined lack or dysfunction of LDL receptors and plasma LDL cholesterol levels >13.0 mmol/L (>500 mg/dL); patients with coronary heart disease (CHD) documented by clinical symptoms and imaging procedures in which over a period of at least 3 months the plasma LDL cholesterol levels cannot be lowered below 3.3 mmol/L (130 mg/dL) by a generally accepted, maximal drug-induced and documented therapy in combination with a cholesterol-lowering diet; and patients with progression of their CHD documented by clinical symptoms and imaging procedures and repeated plasma Lp(a) levels >60 mg/dL, even if the plasma LDL cholesterol levels are lower than 3.3 mmol/L (130 mg/dL). Respective goals for LDL cholesterol concentrations for high-risk patients have been recently defined by various international societies. To safely put into practice the recommendations for LDL-apheresis previously mentioned, standardized treatment guidelines for LDL-apheresis need to be established in Germany that should be supervised by an appropriate registry.
