RATIONALE: Chronic active Epstein-Barr virus infection (CAEBV) associated with hemophagocytic syndrome (HPS) and extra-nodal natural killer (NK)/T-cell lymphoma (ENKL) is a rare life-threatening disorder. This disease is easily misdiagnosed because of its varied presentations. PATIENT CONCERNS: An 18-year-old girl was admitted to our hospital with a history of edema in the lower limbs and intermittent fever lasting for more than 1 month. At admission, she had severe liver injury of unknown etiology...

In order to clarify the mechanisms underlying the development of inflammation in chronic active Epstein-Barr virus infection (CABEV), we examined cytokine production using patient samples. Eleven patients were analyzed. The serum concentrations of IFN-γ, TNF-α, and IL-6 were significantly higher in patients than in healthy donors. The mRNAs of these cytokines in peripheral blood mononuclear cells were elevated in patients as compared with healthy donors. The mRNA of IFN-γ was significantly higher in patients than in healthy donors...

The human herpes virus, Epstein-Barr virus (EBV), is a known oncogenic virus and plays important roles in life-threatening T/NK-cell lymphoproliferative disorders (T/NK-cell LPD) such as hypersensitivity to mosquito bite (HMB), chronic active EBV infection (CAEBV), and NK/T-cell lymphoma/leukemia. During the clinical courses of HMB and CAEBV, patients frequently develop malignant lymphomas and the diseases passively progress sequentially. In the present study, gene expression of CD16((-))CD56((+))-, EBV((+)) HMB, CAEBV, NK-lymphoma, and NK-leukemia cell lines, which were established from patients, was analyzed using oligonucleotide microarrays and compared to that of CD56(bright)CD16(dim/-) NK cells from healthy donors...

Epstein-Barr virus (EBV) has been detected in several T- and NK-cell neoplasms such as extranodal NK/T-cell lymphoma nasal type, aggressive NK-cell leukemia, EBV-positive peripheral T-cell lymphoma, systemic EBV-positive T-cell lymphoma of childhood, and chronic active EBV infection (CAEBV). However, how this virus contributes to lymphomagenesis in T or NK cells remains largely unknown. Here, we examined NF-κB activation in EBV-positive T or NK cell lines, SNT8, SNT15, SNT16, SNK6, and primary EBV-positive and clonally proliferating T/NK cells obtained from the peripheral blood of patients with CAEBV...

Chronic active Epstein-Barr virus infection (CAEBV) is a prototype of the EBV-associated T- or NK-cell lymphoproliferative diseases, which also include hypersensitivity to mosquito bites and severe-type hydroavacciniforme. The manifestations of CAEBV are often self-limiting with minimum supportive care or only prednisolone and cyclosporine A with or without etoposide. However, allogeneic hematopoietic stem cell transplantation (HSCT) is the only cure, without which patients with CAEBV die within several years...

Epstein-Barr virus (EBV) primary infection is usually asymptomatic, but it sometimes progresses to infectious mononucleosis (IM). Occasionally, some people develop chronic active EBV infection (CAEBV) with underlying immunodeficiency, which belongs to a continuous spectrum of EBV-associated lymphoproliferative disorders (EBV(+) LPD) with heterogeneous clinical presentations and high mortality. It has been well established that T cell-mediated immune response plays a critical role in the disease evolution of EBV infection...

In recent years, there are increasing articles concerning Epstein-Barr virus associated lymphoproliferative disorder (EBV+ LPD), and the name of EBV+ LPD is used widely. However, the meaning of EBV+ LPD used is not the same, which triggered confusion of the understanding and obstacles of the communication. In order to solve this problem. Literature was reviewed with combination of our cases to clarify the concept of EBV+ LPD and to expound our understanding about it. In general, it is currently accepted that EBV+ LPD refers to a spectrum of lymphoid tissue diseases with EBV infection, including hyperplasia, borderline lesions, and neoplastic diseases...

This article will focus on the cutaneous lymphoproliferative disorders associated with EBV, with an emphasis on the upcoming changes in the revised 4th Edition of the WHO classification of tumors of the hematopoietic system, many of which deal with cutaneous disorders derived from NK-cells or T-cells. Extranodal NK/T-cell lymphoma usually presents in the upper aerodigestive tract, but can involve the skin secondarily. EBV-associated T- and NK-cell lymphoproliferative disorders (LPD) in the pediatric age group include the systemic diseases, chronic active EBV infection (CAEBV) and systemic EBV+ T-cell lymphoma of childhood...

A 41-year-old man was referred to our hospital for treatment of anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Chronic active Epstein-Barr virus (CAEBV) was diagnosed based on the findings of elevated EBV antibody titers and positive EBV-DNA in the peripheral blood, and cord blood stem cell transplantation (CBT) was performed. The EBV-DNA levels in the blood fell below the limit of detection. His lymphoma relapsed on Day 165 with the appearance of eruptions, which disappeared after the withdrawal of tacrolimus...

Once the Epstein-Barr virus (EBV) has infected a person, it then latently infects B cells. This latent infection lasts a lifetime. However, EBV can infect T or NK cells (T/NK cells) in rare cases. Therefore, EBV causes various hematological diseases. Among these diseases, CAEBV is regarded as the most problematic because, although it is not particularly uncommon, the diagnostic tests for this disease are not covered by health insurance, a serious illness in the "non-active" periods is lacking, and the appropriate motivation for early initiation of treatment can easily be lost...

A 23-year-old woman presented with a persistent fever and shortness of breath. Computed tomography showed marked pericardial effusion, hepatosplenomegaly, and cervical and mediastinal lymph node swelling. Epstein-Barr virus (EBV) antibody titers were abnormally elevated, and the copy number of EBV-DNA was increased in peripheral blood. Based on these observations, she was diagnosed with chronic active EBV infection (CAEBV). The EBV-infected cells in her peripheral blood were CD4(+)T lymphocytes. Fever and pericardial effusion improved following treatment with a combination of prednisolone, etoposide, and cyclosporine; however, peripheral blood EBV-DNA levels remained high...

Epstein-Barr virus-positive T/NK-cell lymphoproliferative diseases (EBV-T/NK-LPDs) include several overlapping EBV-related conditions with variably aggressive courses. For prognostic categorization, we retrospectively analyzed 42 EBV-T/NK-LPD cases. Male (79% [33/42]), young (≤40 years; 83% [35/42]) patients and T-cell lineage (81% [34/42]; CD8/CD4 = 1.8) were predominant. Clinicopathologically, three systemic and one cutaneous category were developed: hemophagocytic lymphohistiocytosis (HLH; 26% [11/42]), chronic active EBV infection (CAEBV; 31% [13/42]), systemic unclassifiable disease (24% [10/42]), and hydroa vacciniforme/hydroa vacciniforme-like lymphoma (HV/HVL; 19% [8/42])...

Herein, we report the case of a 13-year-old boy with multiple recurrent ulcers on his legs. He developed severe sinusitis at 10 years of age and had significant weight loss (6 kg) in the 2 months prior to admission. Histology of tissue biopsied from the ulcer indicated small vessel vasculitis and granulomatous inflammation. Given that these findings met the diagnostic criteria for granulomatosis with polyangiitis (GPA), he was treated with immunosuppressive agents. Further pathology, however, indicated Epstein-Barr virus (EBV)-encoded RNA (EBER) in most lymphocytes in the same sample...

Epstein-Barr virus (EBV) causes various acute and chronic diseases. Chronic active EBV infection (CAEBV) is characterized by infectious mononucleosis-like symptoms that persist for more than 6 months with high viral loads in peripheral blood and/or an unusual pattern of anti-EBV antibodies. Severe CAEBV is associated with poor prognosis with severe symptoms, an extremely high EBV-related antibody titer, and hematologic complications that often include hemophagocytic lymphohistiocytosis. However, CAEBV which led to the development of aplastic anemia (AA) has not been reported yet...

Chronic active Epstein-Barr virus disease (CAEBV) is a distinct EBV-associated lymphoproliferative disease with a poor prognosis. Although the viral load in blood samples has been widely used for diagnosing CAEBV, well-defined viral load thresholds to guide clinicians are currently lacking. The aim of the present study was to determine standardized diagnostic values for EBV load in blood samples of CAEBV patients using the World Health Organization international standard for reporting. Levels of EBV DNA in 103 peripheral blood mononuclear cells (PBMCs) and 95 plasma/serum samples from 107 cases with CAEBV were quantified and expressed in international units...
