RESUMO
A 59-year-old man with an 18-year history of rheumatoid arthritis who had been treated with steroids, methotrexate, and infliximab presented with a high-grade fever, cervical lymphadenopathy, and hepatosplenomegaly. Epstein-Barr virus (EBV) hepatitis was diagnosed based on the liver histology and EBV antibody titer. The symptoms improved temporarily, but five months later, the fever, skin rash, jaundice, and thrombocytopenia relapsed. Bone marrow and liver biopsies demonstrated infiltration with Reed-Sternberg cells. Based on these findings, the patient was diagnosed with other iatrogenic immunodeficiency-associated lymphoproliferative disorder (OIIA-LPD), Hodgkin lymphoma type. This case followed a rare clinical course, in that acute hepatitis preceded the diagnosis of OIIA-LPD.

A 41-year-old man was referred to our hospital for treatment of anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Chronic active Epstein-Barr virus (CAEBV) was diagnosed based on the findings of elevated EBV antibody titers and positive EBV-DNA in the peripheral blood, and cord blood stem cell transplantation (CBT) was performed. The EBV-DNA levels in the blood fell below the limit of detection. His lymphoma relapsed on Day 165 with the appearance of eruptions, which disappeared after the withdrawal of tacrolimus. One year after transplantation, there were no signs of recurrence. This encouraging result suggests that CBT should be considered for adult cases of CAEBV with aggressive clinical manifestations.

Hypofibrinogenemia (plasma fibrinogen level <150 mg/dl) is occasionally observed after allogeneic hematopoietic stem cell transplantation, and its etiology is often difficult to determine. We herein report that steroids administered for the treatment of graft-versus-host disease (GVHD) are associated with the development of hypofibrinogenemia. We retrospectively analyzed the plasma fibrinogen (Fg) levels in 15 consecutive patients who had been administered 1 mg/kg/day (1 mg/kg group) or 2 mg/kg/day (2 mg/kg group) methylprednisolone for the treatment of Grade II to IV acute GVHD. Hypofibrinogenemia had developed in 8 of the 15 patients (53%) by day 50 after the start of steroid treatment, and was observed in 2 of 6 patients in the 1 mg/kg group and 6 of 9 in the 2 mg/kg group. A significant decrease in the Fg level was observed in the 2 mg/kg group (the median value before starting steroid treatment and that on the 20th day after starting steroid treatment were 506 mg/dl and 180 mg/dl, respectively, P=0.0013). Other possible causes of hypofibrinogenemia, including liver dysfunction or disseminated intravascular coagulation, were confirmed in only 3 patients during the observation period. In conclusion, hypofibrinogenemia commonly occurs in patients treated with steroids, especially those administered 2 mg/kg/day methylprednisolone for the treatment of GVHD.
