Outcomes of liver transplantation for acute fatty liver disease of pregnancy

摘要

Acute fatty liver of pregnancy ( AFLP ) often resolves after pregnancy delivery but can progress to acute liver failure necessitating liver transplantation. We performed a retrospective review of the national Scientific Registry of Transplant Recipients ( SRTR ) data to identify all women in the United States undergoing liver transplantation ( LT ) for acute liver failure ( ALF ) from AFLP from 1991 to 2015, and compared to outcomes in women of childbearing age undergoing transplant for ALF from acetaminophen and ALF from other etiologies. Women with AFLP were likely to be on life support at time of LT and had high rates of renal dysfunction (median Cr 2.1, IQR 1.2‐2.3), and hyperbilirubinemia (median bilirubin 17.1, IQR 11.0, 19.9). Although their early and late LT survival outcomes were comparable to the other indications for LT , cumulative 5‐year graft survival was numerically lower among AFLP patients (54%, 95% CI , 27‐76) compared to APAP (70%, 95% CI , 63‐77) and “Other ALF ” (76%, 95% CI , 72‐80) groups. In conclusion, although AFLP is a rare indication for LT , AFLP patients were as sick or sicker than other women of childbearing age undergoing LT for ALF . Worsened graft survival may be related to higher rates of rejection in the AFLP group.
