Fulminant Epstein-Barr virus (EBV)-driven clonal T-cell lymphoproliferative disorder (T-LPD) is rare and most patients are of Asian origin. The disease usually develops shortly after primary acute EBV infection and the mechanism remains poorly understood. Here we report such a rare case in a 28-year-old Caucasian female with systemic lupus erythematosus (SLE). Immunophenotypic and molecular studies revealed that the proliferating lymphoid cells displayed a CD8(+) T-cell phenotype with clonal rearrangement of the T-cell receptor gamma gene. Epstein-Barr virus-encoded RNA was also observed in the clonal lymphoid cells by in situ hybridization. The patient subsequently developed fatal virus-associated hemophagocytic syndrome one month after the primary acute EBV infection. The case represents the first report of fulminant EBV-driven CD8(+) T-LPD occurring in an immunocompromised Caucasian SLE patient. This study, along with studies of similar Asian cases reported in the literature, suggests that dysregulated immunity due to either acquired or genetically determined susceptibility may result in an abnormal response to primary EBV infection and contribute to the pathogenesis of EBV-mediated fatal T-LPD.

    • "In all previously reported cases, the clinical behaviour was aggressive and showed poor response to intensive chemotherapy and supportive care. Death usually occurs between days and 13 months (mean, 33 days) of initial diagnosis [8]. In this case, death occurred six months after presentation. "

    ABSTRACT: Introduction Systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease is an extremely rare disorder and classically arises following primary acute or chronic active Epstein-Barr virus infection. It is characterized by clonal proliferation of Epstein-Barr virus-infected T-cells with an activated cytotoxic phenotype. This disease has a rapid clinical course and is more frequent in Asia and South America, with relatively few cases being reported in Western countries. The clinical and pathological features of the disease overlap with other conditions including infectious mononucleosis, chronic active Epstein-Barr virus infection, hemophagocytic lymphohistiocytosis and natural killer cell malignancies. We describe the rare case of systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease in a 16-year-old Malay boy. Case presentation He presented with a six-month history of fever and cough, with pulmonary and mediastinal lymphadenopathy and severe pancytopenia. Medium- to large-sized, CD8+ and Epstein-Barr virus-encoded RNA-positive atypical lymphoid cells were present in the bone marrow aspirate. He subsequently developed fatal virus-associated hemophagocytic syndrome and died due to sepsis and multiorgan failure. Conclusions Although systemic Epstein-Barr virus-positive T-cell lymphoproliferative childhood disease is a disorder which is rarely encountered in clinical practice, our case report underlines the importance of a comprehensive diagnostic approach in the management of this disease. A high level of awareness of the disease throughout the diagnosis process for young patients who present with systemic illness and hemophagocytic syndrome may be of great help for the clinical diagnosis of this disease.

    ABSTRACT: The Epstein-Barr virus is responsible for infectious mononucleosis syndrome and is also closely associated to several types of cancer. The main complication involving Epstein-Barr virus infection, both in recipients of hematopoietic stem cells and solid organs, is post-transplant lymphoproliferative disease. The importance of this disease has increased interest in the development of laboratory tools to improve post-transplant monitoring and to detect the disease before clinical evolution. Viral load analysis for Epstein-Barr virus through real-time polymerase chain reaction is, at present, the best tool to measure viral load. However, there is not a consensus on which sample type is the best for the test and what is its predictive value for therapeutic interventions.
