Overlap syndrome in hepatology

Autoimmune liver disease is a heterogeneous group of diseases in which the body’s immune cells and antibodies are directed against its own components of the liver tissue. The main diseases from this group are: autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), primary sclerosing cholangitis. Most often there are classical monovariants of the disease, but in some cases, manifestations of two forms from the autoimmune liver disease are observed at once. The term “overlap syndrome” is used to describe such conditions. The article presents a clinical case of a combination of PBC and AIH, one of the most common overlapping syndromes in practice. Most often there are classical monovariants of the disease, but in some cases there are manifestations of two forms of autoimmune liver diseases. Overlap syndrome is a term used to describe these conditions. This article presents a clinical case of a combination of PBC and AIH, one of the most common cross-linked syndromes in practice.
