Аннотация
HISTORY: A 27-year-old man was admitted because of intermittent fever, fatigue, lymphadenopathy and splenomegaly for 20 years. Chronic administration of 6 - 8 g aspirin per day (self-prescribed) resulted in limited control of symptoms and in the development of analgesic nephropathy.
INVESTIGATIONS: The patient had prominent splenomegaly and lymphadenopathy without histological signs of malignancy. Monocytosis and T-lymphopenia were also present. Infectious disease testing revealed IgG+/IgM- EBV serology and EA-EBV-mRNA nested PCR clearly demonstrated the presence of lytic EBV-proteins in PBMCs.
TREATMENT AND COURSE: As chronic active Epstein-Barr virus infection (CAEBV) was highly probable, treatment with aciclovir, gancilovir and steroids was started. Because treatment failed adoptive T-cell transfer with autologous EBV-specific T-cells was performed. After three consecutive infusions the patient responded with a complete remission of fever, fatigue, lymphadenopathy and splenomegaly without adverse effects. Retrospective real-time PCR analysis showed a decrease in viral load from 62847 copies/ microg DNA to 45 - 250 copies after treatment. The patient remains in stable remission without signs of CAEBV (> 4 years).
CONCLUSION: Adoptive transfer of autologous, EBV-specific T-lymphocytes is a promising treatment in CAEBV.
