|a OBJECTIVE: To study the difference in the EBV-DNA level in peripheral blood mononuclear cells (PBMC) and the type of Epstein-Barr virus (EBV)-infected cells in pediatric patients with chronic active EBV (CAEBV) infection, acute EBV infection (AEBV) and healthy children, and to analyze the relationship between the above difference and the clinical manifestation of CAEBV

|
|a METHOD: Real-time fluorescent quantitative polymerase chain reaction (PCR) was used to detect the EBV-DNA levels in peripheral blood mononuclear cells (PBMC) in 12 normal children, 10 pediatric patients with CAEBV infection and 13 pediatric patients with AEBV infection in our hospital between March 2004 and April 2008. Immunomagnetic bead cell fractionation and fluorescent in situ hybridization (FISH) by EBV encoding RNA-1 ( EBER-1) probe were used in the healthy children, EBV-DNA positive CAEBV patients and AEBV patients to detect the type of EBV-infected cells

|
|a RESULT: The average EBV-DNA level in CAEBV patients' PBMC was (6.8 x 10(7) +/- 1.1 x 10(8)) copies/ml, while the average EBV-DNA level of AEBV patients' PBMC was (1.3 x 10(6) +/- 1.6 x 10(6)) copies/ml. The average EBV-DNA level of CAEBV infected patients' PBMC was significantly higher than that of AEBV infected patients' PBMC (P<0.01). The cell fractionation and FISH in seven CAEBV patients showed that EBV in CAEBV patients infected not only B cells, but NK cells and CD4+ and CD8+ T cells to different degree, and these patients presented recurrent and persistent infectious mononucleosis (IM)-like symptoms. In 6 CAEBV patients infection mainly occurred to T cells, in one case, infection occurred mainly in CD8+ T cells, and the patient died from fulminant and deadly T lymphocytes proliferative syndrome except presenting firstly high fever, enlargment of the liver, spleen, lymphnode and the severe decrease of one or three kinds of blood cells. In 1 CAEBV patient the infection was mainly found in NK cells, who presented with hypersensitivity to mosquito biting and high IgE level (2500 U/ml). But EBV in seven AEBV patients infection was found only in B cells who presented with only IM for one time and no EBV-infected PBMC were found in the remaining 6 healthy children

|
|a CONCLUSION: There are much more EBV replications and different EBV-infected cell types in CAEBV patients. Detection of EBV-DNA level by real-time fluorescent quantitative PCR and the detection of the type of EBV-infected cells may help in diagnosis, treatment and development evaluation of children with CAEBV infection
