[Chronic active Epstein-Barr virus infection treated with reduced intensity stem cell transplantation].
A 31-year-old woman had been suffering from fever and a sore throat since January 1999, and had a left neck lymphadenopathy in December 1999. Pathological findings of the biopsied lymphnode suggested malignant lymphoma. She was finally diagnosed as having a chronic active Epstein-Barr virus(EBV) infection because of abnormal antibody titers against EBV antigens and an increased EBV load in her peripheral blood. After receiving chemotherapy consisting of CHOP and high dose cytarabine, the amount of the EBV genome decreased below the detection limit before BMT. Therefore, instead of a conventional myeloablative transplant, we performed BMT using reduced-intensity conditioning regimens consisting of fludarabine and melphalan from an HLA-identical sibling donor. After 14 months, the patient remained in complete remission. Menstruation occurred on day 83 following BMT, and the serum level of LH and FSH on day 316 were within normal range. Under these circumstances, RIST seems to be one of the curative treatments for the patients with CAEBV with minimal late side effects.
