چکیده

Dialysis and adsorption processes are commonly implemented in liver support devices for the removal of albumin-bound toxins such as tryptophan. In this work, dialysis and adsorption of tryptophan from albumin-containing solutions were investigated; in particular, the effect of albumin concentration on both processes was analysed. Theoretical models accounting for albumin-tryptophan binding were proposed and fitted to the experimental data in order to obtain equilibrium and kinetic parameters. The results allowed to perform a simulation of an albumin-dialysis liver support device session and compare the performance of different dialysate recirculation/regeneration policies.

The elusive goal of liver support--quest for the Holy Grail.

The history of liver support devices is traced from early attempts with dialysis based on the known dialysability of ammonia--the major identified toxin in liver failure--and exchange transfusion with removal of protein-bound toxins, to the later techniques based on whole organ perfusion in extracorporeal circuits. Perfusion through charcoal as an adsorbent represented a major advance and remai...

Extracorporeal liver support-albumin dialysis with the Molecular Adsorbent Recirculating System (MARS).

Extracorporeal liver support has been a much studied topic throughout the last 50 years. Albumin dialysis as a therapeutic option for patients with acute liver failure or acute decompensation of chronic liver disease was introduced in the mid-nineties. The Molecular Adsorbent Recirculating System (MARS) is based on the concept of albumin dialysis and allows for the removal of protein-bound as w...

Extracorporeal detoxification using the molecular adsorbent recirculating system for critically ill patients with liver failure.

Liver failure resulting from different causes and its concomitant complications represent difficult-to-treat conditions with high mortality rates, despite improved therapeutic modalities in intensive care medicine. The accumulation of albumin-bound metabolites that are normally cleared by the liver, such as bilirubin and bile acids, contributes substantially to the development of multiorgan dys...

The molecular adsorbents recycling system as a liver support system based on albumin dialysis: a summary of preclinical investigations, prospective, randomized, controlled clinical trial, and clinical experience from 19 centers.

Artificial liver support aims to prolong survival time of patients with liver failure by detoxification. Albumin as a molecular adsorbent in dialysis solution is capable of attracting even tightly albumin-bound toxins from blood into the dialysate if a specific dialysis membrane is used and if the albumin's binding sites are on-line-purified by a sorbent/dialysis-based recycling system (i.e., m...
