Treatment of PSC
EASL Clinical Practice Guidelines
• The available data base shows that UDCA (15-20 mg/kg/d)
improves serum liver tests and surrogate markers of prognosis
(I/B1), but does not reveal a proven benefit on survival (III/C2). The
limited data base does not yet allow a specific recommendation for
the general use of UDCA in PSC.
• I : Randomized, placebo-controlled trials, meta-analyses
• III : Opinion of respected authorities
• B1 : Moderate evidence – strong recommendation (GRADE)
• C2 : Weak evidence - weak recommendation (GRADE)
EASL Clinical Practice Guidelines, J Hepatol 2009;51:237
Treatment of PSC
AASLD Clinical Practice Guidelines
• In adult patients with PSC, we recommend against the use of
UDCA as medical therapy (IA).
• In adult patients with PSC and overlap syndrome,we recommend
the use of corticosteroids and other immunosuppressive agents for
medical therapy (IC)
• I A : Strong recommendation – strong evidence
• I C : Strong recommendation – weak evidence

Endoscopic dilatation
Treatment of PSC
EASL Clinical Practice Guidelines
• Dominant bile duct strictures with significant cholestasis should be
treated with biliary dilatation (II-2/B1).
• Biliary stent insertion should be reserved for cases where stricture
dilatation and biliary drainage are unsatisfactory (III/C2).
• Prophylactic antibiotic coverage is recommended in this setting
(III/C1).
• II-2 : Cohort- and case-control studies
• III : Opinion of respected authorities
• B1 : Moderate evidence – strong recommendation (GRADE)
• C1/2 : Weak evidence - strong/weak recommendation (GRADE)
EASL Clinical Practice Guidelines, J Hepatol 2009;51:237
Treatment of PSC
AASLD Practice Guidelines
• In patients with increases in serum bilirubin and/or worsening
pruritus progressive bile duct dilatation on imaging studies, and/or
cholangitis, we recommend performing an ERC promptly to exclude
a dominant stricture (IB).
• In patients with dominant strictures from PSC, we recommend
initial management with endoscopic dilatation with or without
stenting (IB).
• We recommend antimicrobial therapy with correction of bile duct
obstruction in dominant strictures to effectively resolve cholangitis
(IA).
• IA : Strong recommendation – strong evidence (GRADE)
• IB : Strong recommendation – moderate evidence (GRADE)
