Autoimmune hepatitis-primary biliary cirrhosis overlap syndrome concomitant with immune hemolytic anemia and immune thrombocytopenic purpura (Evans syndrome)

SummaryAutoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) associated with Evans syndrome; combination of autoimmune hemolytic anemia (AIHA) and immune thrombocytopenic purpura (ITP) has rarely been reported. We report the case of a 53-year-old patient who presented with weakness, myalgia, arthralgia, shortness of breath and purpura. Initial laboratory investigations revealed liver dysfunction, anemia and thrombocytopenia. Anti-nuclear (ANA) and antimitochondrial M2 (AMA M2) antibodies were positive. Diagnose of PBC-AIH overlap was made by clinical, serological and histological investigations. AIHA and ITP was identified with clinical-laboratory findings and bone marrow puncture. She was treated with IVIG followed by prednisolone and ursodeoxycholic acid. Hemoglobin-thrombocytes increased rapidly and transaminases improved at day 8. We have reported the first case in the literature with AIH-PBC overlap syndrome concurrent by ITP and AIHA which suggest the presence of shared genetic susceptibility factors in multiple autoimmune conditions including AIH, PBC, ITP and AIHA.
