Introduction: Autoimmune hepatitis (AIH) may initially present as acute liver failure (ALF). The outcome of liver transplantation (LT) in patients with AIH and ALF is not very well defined. We determined the outcome of LT in UNOS (United Network for Organ Sharing) status 1 adult patients with and without AIH using post-MELD (Model for End-Stage Liver Disease) UNOS data.
Material and methods: For each AIH patient, 3 patients with non-AIH, matched for age ±5 years and donor risk index (DRI) ±5 years, were identified; 200 patients (50 AIH, 150 non-AIH) were found eligible for the study.
Results: Patients with AIH were more likely to be female (p = 0.003), non-Caucasian (p = 0.009), have higher bilirubin (p = 0.003), longer waiting time (p = 0.01), and lower creatinine (p = 0.019). African American patients with AIH were younger (p = 0.003), had lower bilirubin (p = 0.037), and were more likely to have had a prior LT compared to Caucasians (p = 0.02). Kaplan-Meier analysis showed that 5-year post-LT survival was similar in those with and without AIH (p = 0.3). African American with AIH showed a trend for lower 5-year survival compared to Caucasians (55% vs. 80%, p = NS). Women had a better outcome, especially in those with non-AIH (p = 0.002).
Conclusions: Patients with AIH transplanted as status 1 have similar outcomes to those without AIH. Women with non-AIH-related ALF have better survival than their male counterparts.
