A Rare Case Presentation: Diagnosing Primary Biliary Cholangitis in a Male Patient With Concomitant Type 1 Diabetes.

Primary biliary cholangitis (PBC) is characterized as an autoimmune disease that involves the destruction of intrahepatic bile ducts, characteristically leading to a cholestatic liver. The presence of disease-specific antimitochondrial antibodies (AMA) is the gold standard to diagnose PBC. Typically, PBC is known to affect female populations exceedingly over their male counterparts. Associated autoimmune diseases include Sjogren's and Raynaud's syndrome, which are also more prevalent in women. The low incidence rates of men affected with PBC, especially with a concomitant type 1 diabetes diagnosis, have resulted in little being known about the clinical course of the disease in this particular population group. Current research suggests no significant histological, serological, or biochemical differences between PBC in males and females. However, some symptoms and clinical associations may be different. This case report presents the rare case of a male patient with type 1 diabetes recently diagnosed with PBC.
