Summary
Alcoholic liver disease (ALD) is rising, with patients often critically ill. A new liver transplant program aims to help patients with end-stage ALD and less than six months sobriety, challenging traditional criteria.
Area of Science:
- Hepatology
- Transplantation Medicine
- Public Health
Background:
- Alcoholic liver disease (ALD) and alcohol-related deaths have significantly increased in the past two decades.
- Patients with end-stage ALD are frequently referred for liver transplantation with a prognosis of less than six months.
- Traditional transplant criteria often contraindicate listing for patients with less than six months of sobriety due to the stigmatization of ALD.
Purpose of the Study:
- To outline the development of a liver transplant program for patients with end-stage alcoholic liver disease (ALD) and less than six months of sobriety.
- To address the need for revised protocols and institutional changes to accommodate this patient population.
- To challenge the historical 6-month sobriety requirement for liver transplant listing in ALD patients.
Main Methods:
- Development of new clinical protocols for evaluating and managing patients with end-stage ALD.
- Resource allocation and system reworking within a large, urban, academic liver transplant program.
- Transformation of team and institutional culture to support expanded transplant criteria.
Main Results:
- The abstract outlines the steps taken by a major academic liver transplant program.
- Focus on developing a program for patients with end-stage ALD and less than six months sobriety.
- Implies a shift from historical contraindications to a more inclusive approach.
Conclusions:
- The historical 6-month sobriety requirement for liver transplantation in alcoholic liver disease (ALD) patients may not be the sole determining factor for access.
- Implementing new protocols, resources, and cultural shifts is crucial for adapting clinical practice.
- This initiative represents a significant step towards improving transplant access for critically ill ALD patients.

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
