PURPOSE OF REVIEW The mortality of acute liver failure remains unacceptably high and liver transplantation is the only effective treatment available to date. This review focuses on new research developments in the field and aims to provide a pragmatic organ-based treatment approach for liver failure patients requiring intensive care support. RECENT FINDINGS The pathophysiological basis for ce...

Acute liver failure in ICU patients is an often fatal condition in which many patients may die of multiple organ failure in the absence of liver transplantation. In this setting, cardiac injury may be associated with or precipitate a fatal outcome. Troponin-I is a well-established, specific, and sensitive surrogate of acute coronaropathy, with both diagnostic and prognostic value. Troponin-I el...

CONTEXT Artificial and bioartificial support systems may provide a "bridge" for patients with severe liver disease to recovery or transplantation. OBJECTIVE To evaluate the effect of artificial and bioartificial support systems for acute and acute-on-chronic liver failure. DATA SOURCES Randomized trials on any support system vs standard medical therapy were included irrespective of publicat...

Massive hepatic necrosis is a key event underlying acute liver failure, a serious clinical syndrome with high mortality. Massive hepatic necrosis in acute liver failure has unique pathophysiological characteristics including extremely rapid parenchymal cell death and removal. On the other hand, massive necrosis rapidly induces the activation of liver progenitor cells, the so-called "second path...

In summary, the following principles are worth reiterating: 1. In the treatment of acute liver failure, protection of the native liver in anticipation that it will recover, but positioning of the allograft in a manner that optimizes its function for both the short and long term (in the event that the native liver does not recover) are important goals. Therefore, orthotopic positioning offers ad...
