Tóm tắt

Two patients with hemophagocytic lymphohistiocytosis who presented with acute liver failure are reported. Both presented with fever, hepatosplenomegaly, markedly elevated liver function tests, abnormal coagulation profiles, and an increase in serum ferritin. Both infants were diagnosed with neonatal hemochromatosis based on a clinical picture of hepatic insufficiency with hyperferritinemia and were referred for liver transplantation. The first patient died of liver failure and septicemia before transplantation. Review of autopsy material revealed a hepatitis-like pattern and extensive infiltration of liver and other organs including bone marrow by histiocytes, some of which were hemophagocytic. The second patient underwent liver transplantation but died 44 days thereafter from progressive hemophagocytic lymphohistiocytosis. Examination of the resected liver demonstrated a hepatitis-like pattern, proliferation of histiocytes, and hemophagocytosis, and the bone marrow revealed hemophagocytic histiocytosis. Hemophagocytosis recurred in the allograft. Hepatic manifestations are common in hemophagocytic lymphohistiocytosis and overt hepatic failure may occur, but initial presentation as fulminant hepatic failure is not well recognized. Elevated serum ferritin can make the distinction from neonatal hemochromatosis and other forms of neonatal liver failure difficult. Hemophagocytic lymphohistiocytosis should be considered in the differential diagnosis of neonatal liver disease, especially when it is accompanied by cytopenias.
