[Modern treatment of primary biliary cholangitis].

For nearly 30 years ursodeoxycholic acid (UDCA) represented the only pharmacological treatment option available for primary biliary cholangitis (PBC). This changed at the end of 2016 when obeticholic acid was licensed in Europe for PBC patients not responding to UDCA. Novel treatment concepts involving the modulation of nuclear receptor signaling in cholestatic and other liver diseases have led to a host of new potential options, studies and drug candidates for the treatment of PBC. The analysis of large multinational cohorts has additionally confirmed the effectiveness of UDCA in slowing PBC progression, and has led to the development of new definitions for the risk assessment of PBC patients under therapy, which will be an asset for clinical decision making. One issue that remains unresolved is the therapeutic management of extrahepatic symptoms associated with PBC, namely fatigue and pruritus, which are the main factors influencing the quality of life of affected individuals. Their pathophysiological basis is poorly understood and treatment remains unsatisfactory.
