What is the prevalence of Primary Sclerosing Cholangitis?

Primary Sclerosing Cholangitis (PSC) is considered a rare disease, with estimated prevalence rates ranging from 0 to 16 per 100,000 individuals globally, though these figures vary significantly by region. Because many patients remain asymptomatic for years, the true prevalence of Primary Sclerosing Cholangitis is likely higher than reported due to frequent underdiagnosis.

How common is Primary Sclerosing Cholangitis?

Primary Sclerosing Cholangitis is classified as a rare disease. Epidemiological data from Orphanet suggests a point prevalence of approximately 1 to 16 per 100,000 in Western populations. Incidence rates are estimated at roughly 0.5 to 1.3 per 100,000 people per year. At DiseaseMaps.org, 36 community members have connected to share their experiences with Primary Sclerosing Cholangitis, highlighting the real-world impact of this condition on individuals across the globe.

Who is most affected by Primary Sclerosing Cholangitis?

Primary Sclerosing Cholangitis affects both males and females, though it exhibits a distinct gender bias. Clinical data indicates the following demographic patterns:

• Gender Distribution: Men are affected more frequently than women, typically at a ratio of approximately 2:1.


• Age of Onset: The condition is most commonly diagnosed in adults between the ages of 30 and 50, although it can be diagnosed in children and adolescents.


• Geographic Variation: Higher prevalence rates are observed in Northern European and North American populations compared to parts of Asia.

Why is prevalence data for Primary Sclerosing Cholangitis challenging to track?

Accurately measuring the prevalence of Primary Sclerosing Cholangitis is difficult because the disease often has a long, asymptomatic phase. Many individuals are only diagnosed after they develop complications, such as jaundice or liver cirrhosis. Furthermore, because Primary Sclerosing Cholangitis is often associated with Inflammatory Bowel Disease (IBD), some cases may be missed or misidentified in clinical settings that do not perform routine liver function screenings for IBD patients.
