Albumin dialysis is a costly procedure: for a seven-hour treatment with MARS, approximately €300 for 600 mL human serum albumin solution (20%), €1740 for a MARS treatment kit, and €125 for disposables used by the dialysis machine have to be spent. The cost of this therapy adds up to approximately €2165.
Serum albumin, often referred to simply as blood albumin, is an albumin (a type of globular protein) found in vertebrate blood. Human serum albumin is encoded by the ALB gene . [ 2 ] [ 3 ] [ 4 ] Other mammalian forms, such as bovine serum albumin , are chemically similar.
The 3D structure of human serum albumin has been determined by X-ray crystallography to a resolution of 2.5 ångströms (250 pm). [1] Albumin is a 65–70 kDa protein. Albumin comprises three homologous domains that assemble to form a heart-shaped protein. [2] Each domain is a product of two subdomains that possess common structural motifs. [2]
However, albumin is lost at each process stage, with roughly 20% of the albumin lost through precipitation stages before fraction V. In order to purify the albumin, there is an extraction with water, and adjustment to 10% ethanol, pH of 4.5 at −3 °C. Any precipitate formed here is done so by filtration and is an impurity.
Serum albumin accounts for 55% of blood proteins, [1] is a major contributor to maintaining the oncotic pressure of plasma and assists, as a carrier, in the transport of lipids and steroid hormones. Globulins make up 38% of blood proteins and transport ions, hormones, and lipids assisting in immune function.
Human serum albumin solution is usually given to prevent complications from the rapid volume reduction. In addition to being more rapid than diuretics, 4–5 liters of paracentesis is more successful in comparison to diuretic therapy. [132]
Hemolink (Hemosol Inc., Mississauga, Canada) was a haemoglobin solution that contained cross-linked an o-rafinose polymerised human haemoglobin. [10] Hemosol struggled after Phase II trials were halted in 2003 on safety concerns [28] and declared bankruptcy in 2005. [29]
