Major challenges limiting liver transplantation in the United States.

ABSTRACT: Liver transplantation is the gold standard of care in patients with end-stage liver disease and those with tumors of hepatic origin in the setting of liver dysfunction. From 1988 to 2009, liver transplantation in the United States grew 3.7-fold from 1713 to 6320 transplants annually. The expansion of liver transplantation is chiefly driven by scientific breakthroughs that have extended patient and graft survival well beyond those expected 50 years ago. The success of liver transplantation is now its primary obstacle, as the pool of donor livers fails to keep pace with the growing number of patients added to the national liver transplant waiting list. This review focuses on three major challenges facing liver transplantation in the United States and discusses new areas of investigation that address each issue: (1) the need for an expanded number of useable donor organs, (2) the need for improved therapies to treat recurrent hepatitis C after transplantation and (3) the need for improved detection, risk stratification based upon tumor biology and molecular inhibitors to combat hepatocellular carcinoma.

Project description:Background and aimsEleven million unauthorized immigrants reside in the United States and may account for 3% of deceased organ donors. Recently introduced federal and state legislation propose to address access to organ transplantation among unauthorized immigrants. The national landscape of liver transplantation (LT) for unauthorized immigrants is unknown.Approach and resultsWe included all US LT recipients between March 2012 and December 2018 who were linked to Pew Center of Research data to estimate the population of unauthorized immigrants in each US state and by country of origin, based on US Census data. We categorized patients as unauthorized immigrants versus US citizens/residents. The main outcome measures were (1) the proportion of LTs performed for unauthorized immigrants compared with the proportion of unauthorized immigrants among total population in each US state and (2) graft failure and death post-LT. Of 43,192 LT recipients, 43,026 (99.6%) were US citizens/residents and 166 (0.4%) were unauthorized immigrants. Among unauthorized immigrants, most LTs were performed in California (47%) and New York (18%). The absolute difference in proportion of LTs performed for unauthorized immigrants compared with the proportion of unauthorized immigrants among the total population differed among states, ranging from +20% in California to -12% in Texas. The most common countries of birth among LT recipients who were unauthorized immigrants were Mexico (52%), Guatemala (7%), China (6%), El Salvador (5%), and India (5%). In competing risk analysis, unauthorized immigration status (vs. US citizens/residents) was associated with a similar risk of graft failure (subdistribution hazard ratio [sHR] 0.74; 95% confidence interval [CI], 0.40-1.34; P = 0.38) and death (sHR 0.68; 95% CI, 0.36-1.29; P = 0.23).ConclusionsLT for unauthorized immigrants is rare, and disparities in access to LT by state are present. Patient and graft survival among unauthorized immigrants is comparable with citizens/residents.
