Other Iatrogenic Immunodeficiency-associated Lymphoproliferative Disorder, Hodgkin Type, following Epstein-Barr Viral Hepatitis in a Patient with Rheumatoid Arthritis.

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.

Successful Cord Blood Stem Cell Transplantation for an Adult Case of Chronic Active Epstein-Barr Virus Infection.

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.

[Hypofibrinogenemia associated with steroid therapy for the patients who developed GVHD after allogeneic stem cell transplantation].

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.
