1.Diagnostic and prognostic value of autoantibodies in primary biliary cholangitis
Journal of Clinical Hepatology 2020;36(5):1164-1166
Primary biliary cholangitis (PBC) is an autoimmune cholestatic liver disease with unknown etiology. Liver biopsy is an important diagnostic tool, but its clinical application is limited due to its invasiveness. Autoantibodies have special diagnostic and prognostic value for PBC, especially anti-mitochondrial antibodies and antinuclear antibodies, and each antibody has unique clinical significance. This article reviews the diagnostic and prognostic significance of autoantibodies associated with PBC and related research advances.

Objective To evaluate the clinical efficacy of plasma exchange(PE)and double plasma molecular absorption system(DPMAS)in the treatment of primary biliary cholangitis(PBC)and the effect of this therapy on prognosis.Methods The clinical data on 526 PBC patients in our hospital from December 2013 to January 2022 were retrospectively analyzed.The patients were divided into different groups according to different therapies and then matched with propensity.The changes in symptoms,laboratory indexes and MELD scores were compared between two groups before and after treatment,and the clinical efficacy of artificial liver treatment for PBC patients was assessed.The effect of this treatment on the survival outcomes in these patients via comparing the cumulative survival rates at 3,6 and 12 months between the two groups.Results The efficiency was better in the group with artificial liver treatment in addition medical therapy than the group with medical treatment alone,the difference was statistically significant(76.7%vs.55.8%,χ2 = 4.214,and P = 0.040).Cox proportional risk regression showed that TBIL was an independent risk factor affecting the 3-,6-,or 12-month survival in PBC patients.Conclusions Artificial liver support system can effectively relieve symptoms,reduce levels of ALT,AST and TBIL,improve blood coagula-tion function,and lower MELD scores in PBC patients.This therapy revealed a trend of improvement in 3-,6-,or 12-month survival outcomes.
