    Primary sclerosing cholangitis (PSC) is a fatal liver disease with no cure. Early detection via alkaline phosphatase levels in young men, especially those with ulcerative colitis, is crucial for timely diagnosis and management.

    Area of Science:

    • Hepatology
    • Gastroenterology
    • Autoimmune Diseases

    Background:

    • Primary sclerosing cholangitis (PSC) is a progressive, fatal chronic hepatobiliary disorder.
    • Currently, no effective medical or surgical therapies exist for PSC.
    • The syndrome predominantly affects young men and is associated with chronic ulcerative colitis.

    Purpose of the Study:

    • To describe the characteristics and natural history of primary sclerosing cholangitis.
    • To highlight the importance of early diagnosis in asymptomatic or preicteric stages.
    • To emphasize the role of screening and diagnostic tools in identifying PSC.

    Main Methods:

    • Review of clinical characteristics, associations, and natural history of PSC.
    • Discussion of diagnostic markers, including serum alkaline phosphatase and association with ulcerative colitis.

  • Consideration of diagnostic procedures such as endoscopic retrograde cholangiography and liver biopsy.

    • Main Results:

    • PSC is characterized by chronic cholestasis, hepatic copper overload, and few serologic markers.
    • The disease progresses slowly over years, potentially leading to cirrhosis, portal hypertension, and bile duct cancer.
    • Elevated serum alkaline phosphatase in young men, particularly those with ulcerative colitis, suggests PSC.

    Conclusions:

    • Increased screening may lead to earlier PSC diagnosis.
    • Prompt diagnostic evaluation is recommended for individuals with suggestive clinical and biochemical findings.
    • Endoscopic retrograde cholangiography and liver biopsy are key diagnostic studies for suspected PSC.
