Prior to 1980 the drug therapy of hereditary hypercholesterolaemia was, as compared to nowadays standards, rather limited. There was virtually no effective therapy for homozygous patients, though plasma exchange introduced in France and Britain, demonstrated the use-fullness of the introduction of apheresis techniques. Parallel to the improvement of cholesterol lowering drug therapy for heterozygous patients, apheresis was developed as therapeutic affinity chromatography since 1980 at the university of Cologne for both homozygous and therapy refractory heterozygous patients. This development was named LDL-Apheresis based on the specificity for the removal of Apoprotein B bound cholesterol, the capacity due to the development of a repetitive cycling technique and the economy determined from the reuse of affinity chromatography columns for each single patient. The capacity of the system allowed for the introduction of new standards of post-treatment values such as 100 mg/dl total cholesterol or alternatively 50 mg/dl LDL-cholesterol and if cholesterol lowering drugs can also applied for a limited extent the rebound can be also slowed down. After 33 years of experience with seven homozygotes and 32 heterozygotes without treatment alternative, we found that in addition to the improvement of the quality of live the extension of live expectancy are the real proof of a therapeutic success as compared to other diagnostic procedures. The average live expectancy of our seven homozygous patients is 45.6 years; our oldest heterozygous patient is 81 years. There are no comparable long term data at present available neither from studies using drugs nor from subsequently developed apheresis techniques which also removed LDL-cholesterol together with plasma constituents not participating in the development of atherosclerosis. Also two homozygous patients giving birth to four children without complication support our concept of aggressive cholesterol lowering therapy being without major side effects (3–4% minor undesired reactions).
