A New Series of Sorbent Devices for Multiple Clinical Purposes: Current Evidence and Future Directions

Abstract

Adsorption is an extracorporeal technique utilized for blood purification. It complements convection and diffusion (the main modalities of solute removal). It involves the passage of blood (or plasma) through an adsorption cartridge, where solutes are removed by direct binding to the sorbent material. Over the years, new adsorption cartridges, with improved characteristics have been developed. Furthermore, the therapeutic applications of adsorption have expanded. These now involve the treatment of inflammatory conditions, chronic uremic symptoms, and autoimmune disease, in addition to intoxication, which was once considered the classical indication for adsorption therapy. HA130, HA230, and HA330 (Jafron, Zhuhai City, China) are among the widely used adsorption cartridges in China. There has been sufficient body of evidence to support their effectiveness and safety. In this review, we aim to highlight their main clinical applications.
