Experience of MARS therapy with and without transplantation in 101 patients with liver insufficiency

Liver support devices are used to treat life-threatening organ dysfunction until a hepatic graft is available or recovery of the native liver. We used a blood purification system-molecular adsorbent recycling system (MARS)-that is based on removal of both protein-bound and water-soluble substances and toxins. Within 2.5 years we treated 101 patients, who were stratified to three subgroups: acute liver failure (ALF; n = 56), acute decompensation in chronic liver failure (AcOCh; n = 35) and liver graft failure (n = 10). MARS seems to be a promising therapy for ALF, allowing the patient's own liver to recover or to gain enough time to find a liver graft. The most promising results, namely the highest number of livers to recovery were observed among acute patients with liver failure due to a toxic etiology. However, we did not discover much benefit of MARS for patients with AcOCh without liver transplantation.
