RT Journal Article T1 Autoimmune hepatitis as a complication of common variable immunodeficiency. A1 Queirós, Patrícia de Oliveira A1 Sousa Martín, José Manuel AB In common variable immunodeficiency (CVID) there is a deregulation of the immune system, which frequently leads to an increased risk of infections, but also to autoimmunity phenomena. Autoimmune hepatitis may develop at any time of CVID's evolution, but it is difficult to diagnose due to the frequent absence of autoantibodies and low levels of IgG. Early diagnosis is important because targeted treatment may allow disease improvement. We present a case of autoimmune hepatitis in a patient with CVID.
