Introduction

Appreciation of the spectrum of clinical features of primary
biliary cirrhosis (PBC) has evolved considerably over the past
few decades. Although the substantial female predominance documented
in early series remains true today, it has become clear that
other so called classical clinical features, such
as symptoms of jaundice, pruritis and fatigue, and even biochemical
markers of cholestasis, need not necessarily be present. Only
a small minority of patients nowadays present with liver failure
and most are even identified while asymptomatic, with up to
80% of patients in recently reported series having no PBC-related
symptoms at the time of diagnosis, compared to only 4% some
30 years ago (Table 1).
17 The diagnosis of PBC in asymptomatic
patients is usually established after the chance finding of
an abnormal physical sign, such as hepatomegaly, or, more often,
an elevated serum alkaline phosphatase level during the course
of an unrelated illness. Alternatively,
