Insights

Low-density lipoprotein (LDL) apheresis helps patients with coronary heart disease when cholesterol goals aren't met. Immunoadsorption, an affinity chromatography method, has unique pros and cons for patient selection.

Area of Science:

  • Cardiovascular Medicine
  • Biochemistry

Background:

  • Coronary heart disease (CHD) management often requires lowering low-density lipoprotein (LDL) cholesterol.
  • Some patients with CHD do not reach target LDL cholesterol levels with standard therapies.
  • LDL apheresis is an established extracorporeal treatment for severe hypercholesterolemia.

Purpose of the Study:

  • To review the therapeutic utility of LDL apheresis in patients with CHD.
  • To discuss immunoadsorption as a specific apheresis technique.
  • To highlight the advantages and disadvantages of immunoadsorption for patient selection.

Main Methods:

  • Review of existing literature on LDL apheresis and immunoadsorption.
  • Discussion of the principles of affinity chromatography used in immunoadsorption.
  • Analysis of clinical data and guidelines related to apheresis therapy.

Main Results:

  • LDL apheresis is effective for patients with CHD unresponsive to conventional lipid-lowering treatments.
  • Immunoadsorption, the first commercial apheresis technique, utilizes affinity chromatography.
  • The selection of an apheresis method requires careful consideration of individual patient factors, including the specific benefits and drawbacks of immunoadsorption.

Conclusions:

  • LDL apheresis offers a valuable therapeutic option for select CHD patients.
  • Immunoadsorption is a key technique with distinct characteristics.
  • Personalized patient management is crucial when choosing among available apheresis strategies.

Drug Elimination: Non-Renal Routes

The liver plays a pivotal role in eliminating drugs and their metabolites, primarily through a process known as biliary excretion. This process involves the hepatocytes, the primary cells in the liver that generate bile. A range of transporters actively expels polar drugs or hydrophilic drug metabolites into the bile, which transports the drugs and metabolites into the small intestine. From here, they are eventually expelled from the body through feces. In some instances, the original drug or a...
Lipid Absorption01:24

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...
