Twenty patients (20/101, 19.8%) presented with LF, and they were more likely to be black (70% versus 7.4%, P = 0.001), require referral for liver transplantation (LT) (70% versus 24.6%, P < 0.0001), and have a higher mortality (45% versus 4.9%, P < 0.0001), compared to those without LF. Of the 14 (70%) patients with LF who were treated medically with steroids, seven (50%) responded (Table 1). Responders had a Model for End-Stage Liver Disease (MELD) score at admission = 28 and were more likely to have cirrhosis (71.1% versus 28.5%); they showed a stable trend in serum bilirubin (mg/dL) (15.2 ± 13.2 versus 14.1 ± 14.1) and INR (1.8 ± 0.4 versus 1.8 ± 0.5) after a mean of 3.7 ± 0.6 days of steroid therapy. In contrast, nonresponders showed a worsening of serum bilirubin (22.5 ± 4.2 versus 23.1 ± 5.6) and INR (3.0 ± 1.5 versus 3.6 ± 2.1). All responders survived without need for a LT, whereas all nonresponders had a fatal outcome (of whom one died after LT). Six patients (30%) with LF were not treated medically, of whom five had submassive necrosis on liver biopsy. Five of these six patients underwent transplantation and all but one survived. One could not undergo transplantation due to development of fatal cholangitis.In conclusion, about 20% of patients with AIH have LF at initial presentation. A lower MELD score at admission (= 28), more severe hepatic fibrosis, and an early (within 4 days of steroid therapy) improvement or stabilization in serum bilirubin and INR identify those who are likely to respond to steroid therapy, and thus survive without LT. Our observations need further corroboration, but if confirmed, such a stratification strategy could optimize care of patients with AIH who present with LF.
