A recent case-report study (D Krebs-Schmitt et al. JPGN 2019; 68: 169-74) describes how progressive familial intrahepatic cholestasis (PFIC) due to bile salt export pump (BSEP) deficiency can recur after liver transplantation.
BSEP deficiency due to mutations in ABCB11 gene causes the development of PFIC type 2. In this case report, the authors describe recurrence of BSEP-deficiency following liver transplantaion in 3 patients.
- Following liver transplantation, patients with PFIC 2 can develop antibodies to BSEP as this antigen was not present in the pretransplant period. Since initial reports, more than 20 patients have been described. “In most of these cases, intensifying the immunosuppression led to normalization of graft function.”
- In this case report, the 3 patients ultimately required retransplantation due to recurrent disease and one patient died (following retransplantation). One patient also received stem cell transplantation after a complicated course.
