The liver is an essential multifunctional organ. It synthesises essential proteins; is involved in fat, carbohydrate and protein metabolisms; regulates the storage of vitamins and glucose among others; and plays a key role in blood detoxification.
Severe liver failure can cause the patient’s blood to become overloaded with toxins. This can prevent the regeneration of liver cells as well as damage other organs. For many years, conventional extracorporeal blood purification methods have been used to help detoxify the blood in the event of liver failure. However, dialysis alone is usually insufficient, as it only removes water-soluble toxins and metabolic products up to a certain molecular size. Furthermore, liver failure also gives rise to numerous toxins that are bound to albumin (e.g., bilirubin, bile acids, long-chain fatty acids, phenols) and do not yield to hemodialysis. Adsorption can effectively remove such toxins from the blood.
