Abstract
Chronic active Epstein-Barr virus (CAEBV) infection of the T-cell or Natural killer (NK)-cell type, systemic form (systemic CAEBV or sCAEBV) was defined by the WHO in 2017 as an EBV-related lymphoproliferative disorder and is listed as an EBV-positive T-cell and NK-cell proliferation. The clinical manifestations and prognoses are heterogeneous. This makes systemic CAEBV indistinguishable from other EBV-positive T-cell and NK-cell proliferations. Early diagnosis of systemic CAEBV and early hematopoietic stem cell transplantation can improve patient prognosis. At present, the diagnosis of systemic CAEBV relies mainly on age, clinical manifestations, and cell lineage, incurring missed diagnosis, misdiagnosis, long diagnosis time, and inability to identify high-risk systemic CAEBV early. The diagnostic methods for systemic CAEBV are complicated and lack systematic description. The recent development of diagnostic procedures, including molecular biological and immunological techniques such as flow cytometry, has provided us with the ability to better understand the proliferation of other EBV-positive T cells and NK cells, but there is no definitive review of their value in diagnosing systemic CAEBV. This article summarizes the recent progress in systemic CAEBV differential diagnosis and the prospects of flow cytometry.

Abstract
Two atypical cases of infectious mononucleosis in two teenagers with initially negative serology and non-evocative blood examinations are reported. The first patient had recently traveled to Africa, and Epstein-Barr virus negative serology led us to make many extensive investigations. The second patient complained of asthenia for a month, and PET/CT was performed to suspicion of lymphoma. PET scan revealed hypermetabolic lymph nodes in the supradiaphragmatic and subdiaphragmatic stations, along with18F-FDG uptake in the spleen and pharynx, raising more suspicion of lymphoma. Fortunately, Epstein-Barr virus DNA testing was performed and turned positive in both cases, and Epstein-Barr virus serology subsequently became positive. Diagnosing EBV infection can be challenging in rare cases, as EBV-specific serology may be negative in the early stages and confounding factors may be present. Therefore, Epstein-Barr virus DNA testing should be considered early in the diagnostic algorithm to prevent unnecessary investigations in similar cases.

Abstract
The metabolism of cancer cells and Epstein-Barr virus (EBV) infected cells have remarkable similarities. Cancer cells frequently reprogram metabolic pathways to augment their ability to support abnormal rates of proliferation and promote intra-organismal spread through metastatic invasion. On the other hand, EBV is also capable of manipulating host cell metabolism to enable sustained growth and division during latency as well as intra- and inter-individual transmission during lytic replication. It comes as no surprise that EBV, the first oncogenic virus to be described in humans, is a key driver for a significant fraction of human malignancies in the world (~1% of all cancers), both in terms of new diagnoses and attributable deaths each year. Understanding the contributions of metabolic pathways that underpin transformation and virus replication will be important for delineating new therapeutic targets and designing nutritional interventions to reduce disease burden. In this review, we summarise research hitherto conducted on the means and impact of various metabolic changes induced by EBV and discuss existing and potential treatment options targeting metabolic vulnerabilities in EBV-associated diseases.

Abstract
Chronic active Epstein–Barr virus (CAEBV) infection is a rare and progressive systemic lymphoproliferative disorder often beginning as an infectious mononucleosis (IM)-like illness. It manifests with fever, splenomegaly, hepatitis, lymphadenopathy, and occasionally cytopenias, pneumonitis, and vasculitis. We report a 23-year-old woman with fever and subcutaneous nodules first appearing on the limbs and then spreading to the body. Peripheral blood EBV antibodies were elevated and EBV-DNA loads significantly increased. A skin and lymph node biopsy identified T cell-based lymphocyte infiltration and EBV-encoded RNA positivity (EBER+). CAEBV was finally diagnosed. During the illness, her disease progressed to hemophagocytic syndrome (HPS). The patient then successfully received an allogeneic hematopoietic stem cell transplantation (HSCT) at 6 months. Current follow-up at 2 years indicated a stable condition and six negative EBV-DNA tests, and we reviewed the clinical manifestations, mechanism, diagnosis and differential diagnosis, treatment, and prognosis of CAEBV. Finally, subcutaneous nodules may occur when CAEBV invades the skin; therefore, clinicians must identify the cause of these nodules early. HSCT is effective but its timing must be appropriate.

[PMID: 35127776 PMCID: PMC8813965 DOI: 10.3389/fmed.2021.836438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Accepted: 12/30/2021] [Indexed: 11/13/2022] Open
Abstract
Objective To evaluate the role of pre-therapeutic 18F-FDG PET/CT in pediatric hemophagocytic lymphohistiocytosis (HLH) with Epstein-Barr virus (EBV) infection. Methods This retrospective study included 29 HLH children (1–16 years) with EBV infection, who underwent pre-therapeutic 18F-FDG PET/CT from July 2018 to November 2020. Pathology results were considered as the reference standard. These patients were divided into two groups: EBV-induced malignancy-associated HLH (M-HLH, N = 9) and EBV-induced non-malignancy-associated HLH (NM-HLH, N = 20). The regions of interest (ROIs) of the liver, spleen (Sp), bone marrow (BM), lymph nodes (LN), hypermetabolic lesions, liver background (LiBG), and mediastinum (M) were drawn with software 3D-Slicer. The volumetric and metabolic parameters, including maximum standard uptake value (SUVmax), metabolic tumor volume, and total lesion glycolysis of these ROIs, clinical parameters, and laboratory parameters were compared between the two groups. The efficiency of the above parameters in predicting the treatment response and overall survival (OS) was analyzed. Results Receiver operating characteristic curve analysis indicated that SUVmax-lesions and SUVmax-LN/M (AUC = 0.822, 0.819, cut-off = 6.04, 5.74, respectively) performed better in differentiating M-HLH from NM-HLH. It had the best diagnostic performance when age was added with the SUVmax-LN/M (AUC = 0.933, sensitivity = 100%, specificity = 85.0%). The presence of extranodal hypermetabolic lesions in multiple organs indicated the M-HLH (P = 0.022). Older age, higher SUVmax-LN and SUVmax-lesions, and the presence of serous effusion were associated with poorer treatment response at the 2nd and 4th week (not reaching partial remission). Multivariate analysis showed that SUVmax-lesions > 7.66 and SUVmax-Sp/LiBG > 2.01 were independent prognostic factors for overall survival (P = 0.025, 0.036, respectively). Conclusions 18F-FDG PET/CT could be a valuable technique for identifying the underlying malignancy and predicting prognosis in pediatric HLH with EBV infection. M-HLH could be considered when SUVmax-lesions > 6.04, SUVmax-LN/M > 5.74, and the presence of extranodal hypermetabolic lesions in multiple organs on 18F-FDG PET/CT. SUVmax-lesions and SUVmax-Sp/LiBG might be independent prognostic factors for OS.

Abstract
Chronic active Epstein-Barr virus infection (CAEBV) is a disease where Epstein-Barr virus (EBV)-infected T- or NK-cells are activated and proliferate clonally. The symptoms of this dual-faced disease include systemic inflammation and multiple organ failures caused by the invasion of infected cells: inflammation and neoplasm. At present, the only effective treatment strategy to eradicate EBV-infected cells is allogeneic stem cell transplantation. Lately, the investigation into the disease's pathogenic mechanism and pathophysiology has been advancing. In this review, I will evaluate the new definition in the 2017 WHO classification, present the advancements in the study of CAEBV, and unfold the future direction.

Abstract
BACKGROUND General practitioners encounter the vast majority of patients with Epstein-Barr virus-related disease, i.e. infectious mononucleosis in children and adolescents. With the expanding knowledge regarding the multifaceted role of Epstein-Barr virus in both benign and malignant disease we chose to focus this review on Epstein-Barr virus-related conditions with relevance to the general practitioners. A PubMed and Google Scholar literature search was performed using PubMed's MeSH terms of relevance to Epstein-Barr virus/infectious mononucleosis in regard to complications and associated conditions. MAIN TEXT In the present review, these included three early complications; hepatitis, splenic rupture and airway compromise, as well as possible late conditions; lymphoproliferative cancers, multiple sclerosis, rheumatoid arthritis, and chronic active Epstein-Barr virus infection. This review thus highlights recent advances in the understanding of Epstein-Barr virus pathogenesis, focusing on management, acute complications, referral indications and potentially associated conditions. CONCLUSIONS Hepatitis is a common and self-limiting early complication to infectious mononucleosis and should be monitored with liver tests in more symptomatic cases. Splenic rupture is rare. Most cases are seen within 3 weeks after diagnosis of infectious mononucleosis and may occur spontaneously. There is no consensus on the safe return to physical activities, and ultrasonic assessment of spleen size may provide the best estimate of risk. Airway compromise due to tonsil enlargement is encountered in a minority of patients and should be treated with systemic corticosteroids during hospitalization. Association between lymphoproliferative cancers, especially Hodgkin lymphoma and Burkitt lymphoma, and infectious mononucleosis are well-established. Epstein-Barr virus infection/infectious mononucleosis as a risk factor for multiple sclerosis has been documented and may be linked to genetic susceptibility. Chronic active Epstein-Barr virus infection is rare. However, a general practitioner should be aware of this as a differential diagnosis in patients with persisting symptoms of infectious mononucleosis for more than 3 months.

Chronic active Epstein-Barr virus infection of T-cell type, systemic form in an African migrant: case report and review of the literature on diagnostics standards and therapeutic options. BMC Cancer 2018; 18:941. [PMID: 30285657 PMCID: PMC6169008 DOI: 10.1186/s12885-018-4861-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2018] [Accepted: 09/26/2018] [Indexed: 11/10/2022] Open
Abstract
Background Chronic active Epstein-Barr virus (EBV) infection (CAEBV) of the T-/NK-cell type, systemic form is a rare and potentially life-threatening illness caused by persistent EBV infection. The highest incidence is found in children and adolescents with increased frequency among Asians and Native Americans, while the disease is uncommon in Western countries. Typically patients present with unspecific symptoms, like fever, lymphadenopathy, hepatosplenomegaly and liver dysfunction. Due to fatal complications including hemophagocytic syndrome, coagulopathy, multiple organ failure and development of EBV-positive lymphoproliferative disease (LPD) or lymphoma early diagnosis is critical for successful treatment. However, in consequence of the lack of experience due to the low incidence in Europe, a broad spectrum of clinical manifestations and a particularly unexpected group of patients, diagnosis can be challenging. Inhere we describe the clinicopathological findings of an African adult with CAEBV associated LPD with a brief review of the literature. Case presentation A 42-year-old African man with fever, enlargement of the spleen and a suspected epileptic seizure was referred to our hospital. Diagnostic testing repeatedly revealed a massive EBV-DNA load in peripheral blood. Whole-body PET-CT-scan presented a strong uptake at multiple bone marrow sites, the thyroid and the adrenal glands. Histopathological analysis of bone marrow and thyroid gland revealed a highly proliferating, atypical and predominantly intravascular cytotoxic T-cell population with intracellular EBV-encoded RNA. Clonality analysis revealed the presence of polyclonal T-cell-receptor. Based on these findings a CAEBV of the T-/NK-cell type, systemic form was diagnosed. Subsequent therapy including three cycles of chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisolone resulted in decreased EBV load, clinical improvement and ongoing complete remission. Conclusion Adult-onset CAEBV of T/NK-cell type usually comprises a poor prognosis and is extremely rare in Western countries. Therefore, our case highlights the need for a clinical awareness of this disease in patients with systemic illness and for a comprehensive multidisciplinary diagnostic approach to facilitate diagnosis. Treatment options include antiviral drugs, immunosuppressive agents and systemic chemotherapy with or without allogeneic stem cell transplantation. Given the limited data these options need to be decided upon in each patient individually considering severity of the disease, comorbidities and response.
