We report on a 30-month-old previously healthy Turkish boy who presented with fever, hepatosplenomegaly and generalized lymphadenopathy. He died 4 months after admission in spite of treatment with steroids, acycloguanosine and cyclophosphamide. Epstein-Barr virus (EBV) DNA was detected in the patient's bone marrow and in a lymph node biopsy. Cells from the lymph node biopsy showed monoclonal rearrangements of immunoglobulin heavy chain genes but no rearrangements of T-cell receptor beta-chain genes or immunoglobulin kappa chain genes. Serological data indicated chronic active EBV infection. There was a slight increase of CD8 positive cells in peripheral blood and a normal response to T-cell mitogens. However, T-cell lines established with interleukin 2 from lymph node biopsy completely failed to kill autologous EBV-transformed B-cells and K 562 target cells. Moreover, in regression tests the patient's peripheral blood mononuclear cells completely failed to limit outgrowth of autologous EBV infected B-cells. We conclude that the patient's selective immuno-deficiency had led to the rapid development of EBV-associated monoclonal lymphoproliferation.
