BACKGROUND & AIMS: The amelioration of refractory cholestatic pruritus after plasmapheresis has been reported in single patients. Here, we analyse the efficacy of plasmapheresis in a cohort of patients with primary biliary cholangitis (PBC).
METHODS: Seventeen consecutive patients with PBC (age range 39-85 years, 16 females, 9 with cirrhosis) and refractory pruritus underwent 129 plasmapheresis procedures during 40 admissions. Pruritus was quantified by the 10-point numeric rating scale (NRS) before and after plasmapheresis, as well as ~30 and ~90 days later.
RESULTS: The mean pruritus before plasmapheresis did not differ between patients with and without cirrhosis (P>.05). Cirrhotics presented, however, with significantly higher serum alanine aminotransferase (ALT), aspartate transaminase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP) and bilirubin before plasmapheresis. Plasmapheresis decreased itching to NRS≤5 in all but five admissions: Mean pruritus decreased from 8.3±1.4 to 3.1±2.2 (P<.0001) in the entire cohort. It also led to a significant decrease in serum ALT, ALP, AST, GGT (all P<.001) and bilirubin (P=.002). Antipruritic effect persisted throughout the 90-days follow-up (P<.0001). The amelioration of pruritus was not affected by the presence of cirrhosis.
CONCLUSIONS: Plasmapheresis is a promising method for reducing intractable itch in a significant proportion of PBC patients regardless of liver fibrosis. Long-lasting improvement of symptoms requires repeated procedures.
