Liver Transplant in Acute Liver Failure - Looking Back Over 10 Years.

BACKGROUND

Acute liver failure (ALF) is the leading cause for emergency liver transplantation (LT) all over the world. We looked at the profile of cases who required LT for ALF from a single centre to identify the possible predictors of poor outcomes.

METHODOLOGY: During the 10-year period starting from 2007, 320 cases of ALF were treated at our institution, of which 70 (median age 24 years, Male:Female 1:2) underwent LT. Retrospective analyses of these 70 patients were performed.

RESULTS

Etiology was identifiable in 73% (n = 51) of cases (yellow phosphorous [YP] poisoning [n = 16], Hepatitis A virus [HAV] [n = 15], Hepatitis B virus [HBV] [n = 5], Hepatitis E virus [HEV] [n = 1], anti-tubercular therapy [ATT] induced [n = 6], acute Wilson's [n = 3], and autoimmune [n = 5]]. Upon meeting King's College Hospital criteria, 69 had live donor LT (61 right lobe grafts, three left lobe grafts, five left lateral segment grafts) and one had deceased donor LT. Among these, there were five auxiliary partial orthotopic grafts and four ABO-incompatible transplants. Overall, 90-day mortality was 35.7% (n = 25), predominantly due to sepsis. Significant risk factors for mortality on multivariate analysis included indeterminate etiology, pre-op renal dysfunction, and Grade IV hepatic encephalopathy (HE). Cumulative 10-year survival of the remaining survivors was 95.6% (n = 45).

CONCLUSION

LT for ALF carries high perioperative mortality (35.7%) in those presenting with indeterminate etiology, pre-op renal dysfunction, and Grade IV HE. Nevertheless, if they survive the perioperative period, long-term survival is excellent.
