Cholestatic liver diseases: modern therapeutics.

INTRODUCTION

Cholestatic liver disease encompasses a broad group of disorders related to impaired normal bile formation, secretion, or excretion. These diseases present with symptoms of fatigue, jaundice, pruritus, and biochemical changes.

AREAS COVERED: We focus on updates in the management of autoimmune cholestatic liver disease. The mainstay therapy in PBC is UDCA (ursodeoxycholic acid), but OCA (obeticholic acid) can be considered if suboptimal response or intolerance. Fibrates have shown some promising effects in PBC patients who have not responded to or are intolerant of UDCA and/or OCA; however, they are not FDA approved. Peroxisome Proliferator-Activated Receptor Agonists (PPARs) have emerged as a promising new class of oral agents in PBC. Also, Ileal Bile Acid Transporter (IBAT) inhibitors are being investigated for the treatment of pruritus related to PBC. There are no available treatments for PSC; however, there have been previous investigations into many agents. There are ongoing clinical trials investigating the role of various antibiotics, PPARs, and immunomodulators for the treatment of PSC.

EXPERT OPINION: Ongoing investigations into the treatment of both PBC and PSC are essential. We anticipate that alternative management strategies for PBC and PSC will continue to arise in the next 5-10 years.
