We present an 8 years old girl who was diagnosed at 6 months of age of Progressive Familial Intrahepatic Cholestasis type 2. Although liver transplantation (LT) was classically considered curative for these patients, cholestasis recurrence with normal gamma-glutamyl transpeptidase (GGT), mediated by anti-bile salt export pump (BSEP) antibodies after LT (auto-antibody Induced BSEP Deficiency, AIBD) has been recently reported. Our patient underwent LT at 14 months. During her evolution, patient presented three episodes of acute rejection. Seven years after the LT, the patient presented pruritus with cholestasis and elevation of liver enzymes with persistent normal GGT. Liver biopsy showed intrahepatic cholestasis and giant-cell transformation with very low BSEP activity. Auto-antibodies against BSEP were detected therefore an AIBD was diagnosed. She was treated with Rituximab and immunoadsorption with resolution of the AIBD. As a complication of the treatment she developed a pneumocystis infection successfully treated with corticoids, cotrimoxazol and anidulafungin.

Purpose: Classical criteria for diagnosis of autoimmune hepatitis (AIH) are intended as research tool and are difficult to apply at patient's bedside. We aimed to study the accuracy of simplified criteria and the concordance with the expert diagnosis based on the original criteria. Methods: A cohort of children under study for liver disorder was selected through consecutive sampling to obtain the prevalence of AIH within the group of differential diagnoses. AIH was defined, based on classical criteria, through committee review of medical reports. Validity indicators of the simplified criteria were obtained in an intention to diagnose approach. Optimal cut-off and the area under the receiver operating characteristic (ROC) curve were calculated. Results: Out of 212 cases reviewed, 47.2% were AIH. For the optimal cut-off (6 points), the simplified criteria showed a sensitivity of 72.0% and a specificity of 96.4%, with a 94.7% positive and a 79.4% negative predictive value. The area under the ROC curve was 94.3%. There was a good agreement in the pre-treatment concordance between the classical and the simplified criteria (kappa index, 0.775). Conclusion: Simplified criteria provide a moderate sensitivity for the diagnosis of AIH, but may help in indicating treatment in cases under suspicion with 6 or more points.
