Domino Hepatocyte Transplantation: A Therapeutic Alternative for the Treatment of Acute Liver Failure

الملخص EN

Background and Aims.

Acute liver failure (ALF) is a severe syndrome with an elevated mortality rate, ranging from 40 to 80 %.

Currently, liver transplantation is the only definitive treatment for these patients and new therapies aiming to treat ALF include artificial organs implant and stem cells therapy, for example.

However, a major limitation of liver donors exists.

Living donor liver transplantation (LDLT), split liver transplantation (SLT), and domino liver transplantation (DLT) are some of the available alternatives to treat ALF patients, but these do not reduce the number of patients on waiting lists.

Herein, we discuss domino hepatocyte transplantation (DHT) using livers that would not meet transplantation criteria.

Methods.

We conducted a literature search on PubMed/Medline using acute liver failure, liver transplantation, hepatocyte transplantation, and domino liver transplantation as key words.

Results.

New sources of biochemically functional hepatocytes and therapeutic treatments, in parallel to organ transplantation, may improve liver injury recovery and decrease mortality rates.

Moreover, the literature reports hepatocyte transplantation as a therapeutic alternative for organ shortage.

However, a major challenge remains for a wide clinical application of hepatocytes therapy, i.e., the availability of sufficient amounts of cells for transplantation.

Ideally, hepatocytes isolated from livers rejected for transplantation may be a promising alternative for this problem.

Conclusion.

Our review suggests that DHT may be an excellent strategy to increase cell supplies for hepatocyte transplantation.
