Objective
To determine the natural history of cirrhosis from parenteral nutrition-associated liver disease (PNALD) after resolution of cholestasis with fish oil (FO) therapy
Background
Historically, cirrhosis from PNALD resulted in end-stage liver disease (ESLD), often requiring transplantation for survival. With FO therapy, most children now experience resolution of cholestasis and rarely progress to ESLD. However, outcomes for cirrhosis after resolution of cholestasis are unknown and patients continue to be considered for liver/multivisceral transplantation.
Methods
Prospectively collected data was reviewed for children with cirrhosis due to PNALD who had resolution of cholestasis after treatment with FO from 2004 to 2012. Outcomes evaluated included need for liver/multivisceral transplantation, mortality, and the clinical progression of liver disease.
Results
Fifty-one patients with cirrhosis from PNALD were identified, with 76% demonstrating resolution of cholestasis after FO therapy. The mean direct bilirubin decreased from 6.4 ± 4 mg/dL to 0.2 ± 0.1 mg/dL (p <0.001) 12 months after resolution of cholestasis, with a mean time to resolution of 74 days. None of the patients required transplantation or died from ESLD. Pediatric End-Stage Liver Disease (PELD) scores decreased from 16 ± 4.6 to −1.2 ± 4.6, 12 months after resolution of cholestasis (p <0.001). In children who remained PN-dependent, the PELD score remained normal throughout the follow-up period.
Conclusions
Cirrhosis from PNALD may be stable rather than progressive once cholestasis resolves with FO therapy. Furthermore, these patients may not require transplantation and show no clinical evidence of liver disease progression, even when persistently PN-dependent.
