An analysis of the OPTN/UNOS Liver Transplant Registry.
Based on data reported to the OPTN/UNOS Liver Transplant Registry between 1988-2004: 1. There was a very small difference in 5-year graft survival rates comparing living and deceased donors in adult (4.3%) and pediatric patients (2.4%). 2. Although graft survival rates of split liver transplants were lower than whole liver grafts before 1998, 5-year graft survival results of more recent split grafts (65.8%) have become comparable to those of whole liver grafts (66.5%). Among recipients in good condition, split (67.7%) and whole grafts (70.0%) yielded equivalent survival rates. 3. Lower graft survival rates were noted in ABO incompatible grafts, non-heartbeating donors, regrafted patients, and recipients who were in the ICU before transplantation. 4. There was no recipient gender effect on liver transplant outcome. 5. Primary disease distributions were different for different races. Among adult patients, the largest fraction of white patients had alcoholic cirrhosis. Among Asians, Type B cirrhosis was most frequent. Among pediatric patients, biliary atresia constituted the majority of patients. Most of the patients with alpha-1 antitrypsin deficiency were white. Autoimmune hepatitis was most frequently found among black patients. 6. Although 5-year graft survival of black patients (60.2%) was lower than whites (68.1%), Hispanics (67.6%), and Asians (68.0%), black recipients with PBC (73.3%) and PSC (69.9%) had graft survival rates similar to those of whites (78.1%) (73.6%) and Hispanics (75.3%) (77.1%). 7. Zero HLA-A,-B,-DR mismatched livers had very rapid early failures. HLA matching correlated with graft survival in autoimmune hepatitis patients, but not in cirrhosis patients. 8. Short-term graft survival for liver transplants has improved steadily since 1990. However, long-term graft survival after the first year actually declined over time. 9. In adult transplants, 5-year graft survival of autoimmune-related diseases, PBC (77.3%), PSC (73.3%), AIH (74.2%) yielded higher graft survival rates than those of hepatitis B (71.5%) and C (63.2%). 10. In pediatric patients, 5-year survival of biliary atresia (75.4%), autoimmune cirrhosis (70.8%), and alpha-1-antitrypsin deficiency (85.0%) had high graft survival rates, except for acute liver failure (61.6%). 11. Hepatitis C recurrence is now one of the major causes of graft failure in adults. Thrombosis is a major factor in graft failure for pediatric transplants.
