Summary
Low-density lipoprotein (LDL) apheresis is a safe and effective treatment for severe hyperlipidemia unresponsive to other therapies. Immunoadsorption specifically excels at reducing elevated lipoprotein (a) levels.
Area of Science:
- Cardiology
- Biochemistry
- Medical Technology
Background:
- Severe hyperlipidemia and elevated lipoprotein (a) levels often correlate with poor prognosis in coronary heart disease.
- Conventional therapies including diet and lipid-lowering drugs may be insufficient for refractory cases.
Purpose of the Study:
- To review and compare five different LDL apheresis systems for treating severe hyperlipidemia.
- To evaluate the efficacy and safety of LDL apheresis in patients unresponsive to maximum conservative therapy.
Main Methods:
- Overview of five LDL apheresis techniques: cascade filtration, immunoadsorption, heparin-induced LDL precipitation, dextran sulfate LDL adsorption, and LDL hemoperfusion.
- Analysis of technical and clinical aspects of each method.
Main Results:
- No significant differences were observed among methods regarding cholesterol and triglyceride reduction.
- Immunoadsorption demonstrated superior effectiveness in reducing elevated lipoprotein (a) levels.
- LDL apheresis proved effective and safe for long-term application in refractory hyperlipidemia.
Conclusions:
- LDL apheresis is a crucial therapeutic option for severe hyperlipidemia refractory to conventional treatments.
- The choice of apheresis method may depend on specific patient parameters, particularly elevated lipoprotein (a).

Atherosclerosis I: Introduction
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
Atherosclerosis III: Management
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
