What is the treatment of primary sclerosing cholangitis when the patient has pruritus and no dominant biliary stricture?

Pruritus — persistent, often severe skin itching — affects a substantial proportion of patients with primary sclerosing cholangitis (PSC). When no dominant or relevant biliary stricture or biliary obstruction is present, the management of this symptom follows a structured, stepwise approach.

Clinical Scenario

PSC with pruritus (skin itching) in the absence of a dominant or relevant biliary stricture or biliary obstruction. Many patients with PSC — estimated at 30%–60% — experience pruritus that can be severe and significantly disabling.

Approach Overview

Once a relevant biliary stricture has been ruled out, initial management centres on behavioural and topical measures — including avoidance of heat and hot baths and the use of topical emollients — alongside pharmacological options.

Many patients with PSC (30%–60%) suffer from pruritus, or itch, which can be severe and disabling.

In the absence of a relevant stricture, a stepwise therapeutic approach should be followed starting with heat avoidance, emollients, and/or antihistamines, followed if necessary by first-line (cholestyramine), second-line (sertraline, rifampin, and/or naltrexone), and third-line (phenobarbital, plasmapheresis, and/or phototherapy) therapy, with LT considered for continued refractory symptoms.

Once this is ruled out by MRI/MRCP, patients should be advised to avoid the heat and hot baths and use topical emollients and antihistamines.
