Abstract: Primary biliary cholangitis (PBC) can frequently coexist with other autoimmune diseases (AID). The aim of our study was to determine the prevalence and type of associated autoimmune diseases in a series of PBC. Methods: The medical data of 42 PBC patients were evaluated for associated autoimmune diseases. Results: In the study population, 26 (65%) patients had autoimmune diseases associated, including Autoimmune hepatitis 35.7%, dysthyroidism 12%, Gougerot-Sjogren syndrome 9.5%, rheumatoid arthritis 9.5%, scleroderma 2.3%, Raynaud's phenomenon 2.3%. Conclusion: A large number of autoimmune diseases were associated with PBC patients. Screening for these diseases must be systematic during PBC in order to deal with them early.
