[Primary biliary cholangitis-established and novel therapies]

Patients with primary biliary cholangitis (PBC, formerly primary biliary cirrhosis) and insufficient treatment response or risk factors exhibit a remarkably increased risk for disease progression and associated complications. Furthermore, extrahepatic manifestations may considerably reduce quality of life in affected patients.

This article presents an overview on standard therapy with ursodeoxycholic acid (UDCA) and further therapeutic options in patients with insufficient treatment response. In addition, symptom-orientated therapies will be presented in a practical and compact way.

The current European and German guidelines from 2017 in addition to several research papers and expert opinions are the basis for this review.

Every PBC patient should be treated with UDCA life-long. In case of insufficient response to UDCA, obeticholic acid (OCA) has been approved as second line therapy since 2016. Fibrates and budesonide present off-label options for certain patient subpopulations. Pruritus should initially be treated with colestyramine. In case of insufficient efficacy or intolerance, rifampicin represents the most effective off-label option. If fatigue is present, differential diagnoses shall be excluded and coping strategies combined with regular physical activity can have a positive effect.

UDCA and OCA are effective and approved drugs for treating PBC. Patients with insufficient treatment response or risk factors have to be treated consequently. Due to the improved anti-cholestatic treatment options, therapies to reduce fatigue and pruritus are increasingly important.
