Is Primary Sclerosing Cholangitis contagious?

Primary Sclerosing Cholangitis is not contagious, meaning it cannot be spread through physical contact, bodily fluids, or sharing personal items. It is a chronic, immune-mediated disease of the bile ducts and there is no risk of transmission to family, friends, or caregivers.

What causes Primary Sclerosing Cholangitis?

Primary Sclerosing Cholangitis is primarily considered an autoimmune-related condition where the body’s immune system mistakenly attacks the bile ducts in the liver. While the exact trigger remains unknown, it is not an infectious disease caused by bacteria or viruses. Research suggests a complex interplay between genetic predisposition and environmental factors, but it is not something that can be "caught" from another person.

Why is there confusion regarding the contagiousness of this condition?

Patients often face stigma because Primary Sclerosing Cholangitis involves the liver, an organ frequently associated with viral hepatitis, which *is* contagious. Because of symptoms like jaundice and fatigue, people sometimes mistakenly assume Primary Sclerosing Cholangitis is a communicable infection. It is important to clarify that this condition is purely internal and poses no public health risk.

Are there environmental triggers for Primary Sclerosing Cholangitis?

While the disease is not contagious, researchers are investigating why Primary Sclerosing Cholangitis develops in some individuals but not others. Factors that may influence the progression or onset include:

• Genetic factors: Certain HLA gene variants are more common in patients with the disease.


• Gut Microbiome: Changes in the gut bacteria are frequently studied, as roughly 70-80% of patients with Primary Sclerosing Cholangitis also have Inflammatory Bowel Disease (IBD).


• Immune dysregulation: An abnormal immune response leading to chronic inflammation and scarring of the bile ducts.

Is it safe to live with someone who has this condition?

Yes, it is perfectly safe to live with, share meals, and provide physical care to someone with Primary Sclerosing Cholangitis. There are no precautions needed to prevent the spread of the disease because it is not an infectious process. Close social contact and emotional support are vital for the 36 members of the DiseaseMaps community currently managing this condition.
