520 |a Objective: To discuss the clinical characteristics and management approaches to hepatitis associated aplastic anemia (HAAA) presenting as hemophagocytic lymphohistiocytosis (HLH) at onset. Methods: The clinical data and laboratory results of hospitalized 5 HAAA patients presenting as HLH at onset in Beijing Children's Hospital from January 2017 to May 2019 were analyzed retrospectively. Results: Among 5 cases, there were 4 males and 1 female. The age of onset was 6.0 (2.7-12.7) years. All patients presented with high fever, hepatomegaly, hepatic dysfunction (aspartate aminotransferase 1 716 (1 409-2 570) U/L, alanine aminotransferase 1 699 (937-2 540) U/L) at onset. After admission, the laboratory results showed pancytopenia (white blood cell 1.2 (0.6-6.7) ×10(9)/L, haemoglobin 94 (65-111) g/L, blood platelet 29 (10-41) ×10(9)/L), decreased fibrinogen (1.3 (1.1-2.5) g/L), significantly elevated triglyceride (4.0 (2.8-5.1) mmol/L), ferritin (1 766 (399-5 253) μg/L) and soluble CD25 (27 457 (9 625-44 000) ng/L). Hemophagocytosis was found in the bone marrow smears of all 5 patients. The diagnosis of acute hepatitis and HLH was confirmed. During the treatment of HLH, the blood cells remain below normal level and the further biopsy of bone marrow (iliac bone) indicated low myeloproliferation. After exclusion of congenital bone marrow failure syndromes and other pancytopenic diseases, HAAA was confirmed. After the diagnosis of HAAA, 1 patient received antithymocyte globulin (ATG) and cyclosporin treatment in our hospital, 1 patient received allogeneic stem cell transplantation (HSCT) in other hospital, 2 patients received ATG in other hospitals. Only 1 patient died of severe infection. Conclusions: HAAA can present as HLH at onset. It is mainly manifested by high fever, acute severe hepatitis, pancytopenia, elevated ferritin and hemophagocytosis in the bone marrow. The diagnosis of HAAA should be considered whenever cytopenia could not completely corrected while apparent improvement of HLH and hepatitis related complications were improved after immunosuppressive therapy. ATG or HSCT treatment should be performed as soon as the diagnosis of severe or transfusion dependent aplastic anemia is confirmed
