Chronic active Epstein-Barr virus (CAEBV) infection is a systemic Epstein-Barr virus (EBV) positive lymphoprolifetative disease characterized by fever, lymphadenopathy, splenomegaly, unusual pattern of anti- EBV antibodies, and/or increased EBV genomes in affected tissues. Most cases are from Asia. So far, there is hardly any adult case reported from mainland of China. We herein presented a 33-year-old man with fever, facial erythema and rash, lymphadenopathy, lower limbs weakness, splenomegaly and liver lesion. EBV VCA, EA and EBNA were all positive. EBV DNA could be found in serum and PBMC. In situ hybridization of EBV encoded RNA in skin and liver biopsy was positive. Viral load in serum decreased under interferon alpha therapy. To our knowledge, it’s the first adult case reported from mainland of China.

Objective To observe the expression of inflammatory molecules in bone marrow immune cells of patients with immune-related hematocytopenia (IRH), and to investigate the immune mechanism and clinical significance of the disease.

Methods Total of 36 IRH patients were selected as observation group and 30 healthy people were taken as control group. Serum cytokines levels, activity of immunocytes and expression of HLA-DR were detected. Immune fluorescence was applied to observe the expression state of immunologic molecules and cytokines in IRH patients.

Results Serum cytokines were elevated in various degrees in observation group. Compared with the control group, the cytokines levels were significantly higher (P < 0.05). After treatement with immunosuppressive drugs, the serum levels of cytokines in observation group reduced to a level close to the control group. HLADR were upregulated in activated tissue basophils, eosinophils, dendritic cells (DC) and macrophages of bone marrow in IRH patients, and POX activity in these immunocytes of IRH was higher than that of the control group. Immune molecules were highly expressed in eosinophils, DC and macrophages.

Conclusions It is demonstrated that antibodies or self-reactive lymphocytes were produced in IRH marrow, which would cause lesions of hemocytes, and lead to pathological process finally. Structure of hematopoietic cells mutated and these cells might be acted as target cells of immunocytes in the pathological process. Immunocytes could secrete inflammatory factors and lead to immunologic injury of hemocyte.
