Extracorporal albumin dialysis (MARS) improves cholestasis and normalizes low apo A-I levels in a patient with benign recurrent intrahepatic cholestasis (BRIC).

[benign recurrent intrahepatic cholestasis]

The familial cholestatic diseases Benign Recurrent Intrahepatic Cholestasis (BRIC) and Progessive Familial Intrahepatic Cholestasis type 1 (PFIC1) are characterized by intermittent or permanently elevated plasma bile salt levels, therapy-resistant extreme pruritus and peculiar biochemical abnormalities including low apolipoprotein apo A-I. Previously, symptomatic improvement has been demonstrated in BRIC patients after extracorporal albumin dialysis (MARS). We hypothesized that MARS improves cholestasis, induces changes in the bile salt profile and normalizes apo A-I serum levels in BRIC. A 17-year-old-female patient with BRIC experienced an episode of cholestasis lasting for more than 6 months with extreme pruritus and diarrhoea not responding to standard therapy. During a period of five days the patient was treated 3 x 8 h with MARS. The procedures were well tolerated and resulted in reduction of plasma bile salts by 58%. The plasma bile salt profile changed into a more hydrophilic composition after MARS. Diarrhoea discontinued and the pruritus improved significantly from 9 to 4 on a subjective scale. These effects lasted 4 months until a relapse occurred. Low plasma apo A-I levels (0.52 g/l) normalized after MARS (0.98 g/l). The procedures were well tolerated. Fatigue was noted as the only transient side-effect. In conclusion, MARS may induce a long-term symptomatic improvement and decrease of cholestatic markers in BRIC. Further studies evaluating efficacy and mechanism of MARS in patients with BRIC are needed.
