PURPOSE: This study aimed at correlating Epstein-Barr virus (EBV) infection of systemic AIDS-related non-Hodgkin lymphomas (AIDS-NHL) with the development of a CNS localization of the tumor. PATIENTS AND METHODS: Demographic, epidemiologic, clinical, histologic, and virologic features were collected for all systemic AIDS-NHL patients included in the study (n = 50). Pathologic specimens were classified according to the working formulation for NHL and the Revised European-American Lymphoma classification. EBV infection in tumor tissue samples was studied by EBV small encoded RNA in situ hybridization; EBV-DNA detection in CSF was carried out by nested polymerase chain reaction using Epstein-Barr nuclear antigen-1–specific primers. In addition, selected EBV-positive lymphomas were subjected to a detailed characterization of EBV molecular heterogeneity. RESULTS: Eleven patients had a CNS involvement at some point during their clinical history (four at diagnosis and seven at relapse). Thirty patients (11 with CNS involvement and 19 without) harbored EBV infection of the tumor. Sensitivity, specificity, and positive and negative predictive values of EBV-DNA detection in CSF for CNS involvement by lymphoma were 90%, 100%, 100%, and 97.6%, respectively. Factors significantly predictive of CNS involvement were EBV infection of the tumor (P = .003), an extranodal disease at diagnosis other than CNS (P = .006), and a non-CNS relapse (P = .01). In four cases of CNS involvement, EBV-DNA in CSF preceded any other sign of disease by a mean of 35 days. CONCLUSION: These results show that EBV infection of the tumor clone significantly increases the risk of CNS involvement by systemic AIDS-NHL, without regard of specific molecular features. The detection of EBV-DNA in the CSF of AIDS-NHL patients may select cases with higher risk of CNS involvement and, therefore, may prove useful in the therapeutic stratification of these tumors.

Abstract Objectives This study aimed to compare the clinical features and laboratory tests of infectious mononucleosis (IM) and hemophagocytic syndrome (HLH) caused by Epstein-Barr virus (EBV) in 1-3-year-old children and to explore the risk factor of HLH caused by EBV (EBV-HLH). Methods The clinical data of 92 children with EBV infection admitted in our hospital from 2011 to 2019 were collected; 61 cases were diagnosed as EBV-IM, and 31 cases were diagnosed as EBV-HLH. The subjects’ clinical manifestations and laboratory tests were analyzed retrospectively. Results Compared with EBV-IM patients, EBV-HLH patients had longer durations of fever, both before hospitalization and overall, and a higher probability of hepatomegaly. The levels of ALT, AST, LDH, TG, SF, D-Dimer and the plasma EBV DNA load of EBV-HLH patients were significantly higher than those of EBV-IM patients. The absolute values of CD3+, CD4+, CD8+, NK, and CD3-CD19+ cells and IgA and IgM levels of EBV-HLH patients were significantly lower than those of EBV-IM patients. The plasma EBV DNA load was positively correlated with the PT, TT, α-HBDH, AST, LDH, CK, Scr, BUN, UA, TG, and CRP levels in EBV-HLH patients, and the plasma EBV DNA load was positively correlated with the D-Dimer level in the EBV-IM patients. Among the 10 different potential markers, at the cut-off point of 1721.500 µg/L, the sensitivity and specificity of D-Dimer was 88.90% and 90.20%, respectively. Conclusion The D-Dimer level may be a good prognostic indicator of EBV-HLH caused by EBV.

Basic Level

Nasopharyngeal Carcinoma (NPC) is a cancer that occurs in nasopharynx which is associated with Epstein-Barr Virus (EBV). Mutation agents in nasopharyngeal neoplasms occur because of EBV infection. Transformation of B-cells due to EBV causes hormone imbalance in lymphoid cells or nasopharyngeal epithelial tissue. Rates of EBV infection have been shown to be prognostic to NPC. The basic level of EBV DNA can be used for stratification prognosis, with higher titers showing greater disease severity and worse outcomes. With mathematical models, there is a correlation between the increase in Epstein-Barr Virus and the increase in Invasive Carcinoma Cells or increase in Nasopharyngeal Carcinoma Cells.

The Epstein-Barr virus (EBV) is a common virus in humans and the most common causative agent of Infectious Mononucleosis. EBV primary infection has recently risen in some countries and children below 2 years of age are highly susceptible. The clinical manifestations in children with EB virus infection involve multiple systems, causing severe illness, meaning attention should be paid during diagnosis and treatment. Objective:  This single institution based retrospective study was carried out with the aim of estimating the overall prevalence of EBV infection and identifying high-risk age group among children.  Methods: This study include total 253 patients under 15 years of age found to be  positive for EBV DNA by PCR who were admitted to the Pediatrics Department of Renmin Hospital,(Shiyan, China) during a 4-year period from 2014 to 2017. Patients were divided into three groups; 0-<4years, 4-<6years and 6-<15years. We then calculated the percentage and prevalence of EBV DNA-positive cases. Results: The yearly EBV prevalence rate was 4.99 per 1000 admissions in 2014, 6.97 per 1000 admissions in 2015, 10.42 per 1000 admissions in 2016, and 12.16 per 1000 admissions in 2017. Out of 253 EBV-positive cases, those under 4 years had the highest rate of EBV infection (74.7%). The rate drops to 11.06% in the 4-6 years group, and was 14.22% in the 6-15 years group. Those between 6 months and 1 year are those at the highest risk.  Conclusion: The rate of hospital admission of children due to EBV infection is increasing day by day. Children under 4 years of age are highly susceptible to infection and children of age between 6 months and 1 year are the high-risk group for EBV infection.

Abstract The aim of the present study was to evaluate the relationship of Epstein–Barr virus (EBV) infection and multiple myeloma (MM) and its impact on clinical characteristics and prognosis. Fresh peripheral blood mononuclear cells (PBMCs) from 139 MM patients who had been diagnosed and treated from January 2010 to May 2018 and 50 PBMC samples from healthy donors were obtained. PCR was carried out for detection of EBV-DNA. The results indicated a significantly higher EBV-DNA concentration among 139 MM patients compared with healthy controls (P&lt;0.05). Correlation analysis showed that the expression of EBV-DNA was positively correlated with the serum free light chain ratio (sFLCR) and progressive disease (PD)/relapse (P&lt;0.05). Especially, in EBV-DNA high-expression MM patients, EBV-DNA concentration for patients with sFLCR ≥100 was higher than that of patients with sFLCR &lt;100. EBV-DNA concentration was higher in patients with disease PD/relapse than those without disease PD/relapse. In univariate analysis, the progress free survival (PFS) was inferior in MM patients with high expression of EBV-DNA, high lactate dehydrogenase (LDH), and high-risk according to mSMART and International Myeloma Working Group (IMWG), stage III according to R-ISS staging, extramedullary lesions, and genetic changes (P&lt;0.05). However, in multivariate analysis, LDH, poor karyotype, R-ISS staging, and mSMART were independent prognostic factors for PFS. Taken together, our studies suggest that an association exists between EBV infection and clinical characteristics of MM patients, and EBV infection appears to have a slight impact on the prognosis of MM. However, the results require further validation in other independent prospective MM cohorts.

Abstract Background Immune control of Epstein-Barr virus (EBV) infection is impaired in individuals with HIV. We explored maternal factors associated with EBV acquisition in HIV-exposed uninfected (HEU) infants and the relationship between EBV infection and serious adverse events (SAEs) during the first year of life. Methods 201 HEU infants from Uganda enrolled in the ANRS 12174 trial were tested for antiviral capsid antigen (anti-VCA) antibodies at week 50. Date of infection was estimated by testing EBV DNA at weeks 1, 6, 14, 26, 38, and 50 postpartum on dried blood spots. Results Eighty-seven (43%) infants tested positive for anti-VCA IgG at week 50. Among the 59 infants positive for EBV DNA, 25% were infected within the first 26 weeks. Almost half (12%) were infected before week 14. Shedding of EBV in breast milk was associated with EBV DNA in maternal plasma (P = .009), HIV RNA detection (P = .039), and lower CD4 count (P = .001) and correlated with plasma EBV DNA levels (P = .002). EBV infant infection at week 50 was associated with shedding of EBV in breast milk (P = .009) and young maternal age (P = .029). Occurrence of a clinical SAE, including malaria and pneumonia, was associated with higher levels of EBV DNA in infants (P = .010). Conclusions By assessing EBV infection in HEU infants we observed that infection during the first year is determined by HIV and EBV maternal factors and that EBV DNA levels were higher among infants with clinical SAEs.

Background Epstein-Barr virus (EBV) infection is a common complication in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT), leading to fatal post-transplant lymphoproliferative disorders (PTLD) and other EBV-associated diseases. A few studies suggested that cytomegalovirus (CMV) might play a role in PTLD. In this study, the effect of CMV on EBV DNA-emia and EBV-associated diseases was evaluated in the recipients of allo-HSCT. Methods Three hundred and fifty-two patients undergoing allo-HSCT were enrolled in this prospective study between July 2008 and June 2013. The EBV-DNA and CMV-DNA levels in blood and secretion were monitored by quantitative real-time polymerase chain reaction (RQ-PCR) before and in different time points after transplantation. EBV and CMV DNA-emia were diagnosed when EBV-DNA or CMV-DNA in the blood was positive twice consecutively. Results During the follow-up period, 99 patients (28.1%) developed EBV DNA-emia and 41 (11.6%) developed EBV-associated diseases including 27 EBV-associated PTLD and 14 other EBV-associated diseases. One hundred and fifty-nine patients (45.2%) developed CMV DNA-emia and 10 (2.8%) developed CMV-associated diseases. Of the 99 patients who developed EBV DNA-emia, 56 had CMV DNA-emia before EBV DNA-emia, and the median time from occurrence of CMV DNA-emia to EBV DNA-emia and EBV-associated diseases were 15 (range, 0-269) days and 26 (range, 0-255) days, respectively. Six patients developed co-existing CMV DNA-emia at the time of EBV-associated diseases diagnosed. DNA-emia before EBV infection had positive correlation with EBV DNA-emia (r=0.14, p=0.007) and EBV-associated diseases (r=0.15, p=0.005), but both correlation coefficients were weak. There was a strong positive correlation between EBV DNA-emia and EBV-associated diseases (r=0.56, p<0.001). The patients with CMV DNA-emia had a higher risk for developing EBV infection than those without (OR 2.279, 95% confidence interval [CI] 1.420-3.657, p=0.001). After EBV infection occurred, 15 patients developed CMV DNA-emia, including 4 developed CMV-associated diseases, at a median time of 33 days (range, 12-50 days). EBV infection was not related to CMV DNA-emia (p=0.87) or CMV associated diseases (p=0.27) occurring after EBV infection. Conclusion The results suggest that CMV may play a contributory role in the development of EBV DNA-emia and EBV-associated diseases.

Intestinal Ulcers

Clinical characteristics of intestinal ulcers complicated with Epstein-Barr virus (EBV) infection remain poorly studied. This study is aimed at providing further insight into clinical features of this patient cohort. The presence of serum EBV DNA was assessed in 399 patients with colonic ulcers, of which 30 cases were positive. In EBV-positive patients, the EBV-encoded RNA (EBER) was detected in intestinal tissues of 13 patients (EBER-positive group). The test was negative in 17 patients (EBER-negative group). Acute EBV infection rate in patients with colonic ulcer was 7.52%. Age and sex differences between two groups were not statistically significant. Fever, abdominal lymph node enlargement, and crater-like gouged ulcer morphology were more common in the EBER-positive group ( P < 0.05 ). The albumin level in the EBER-positive group was significantly lower compared to that in the EBER-negative group ( P < 0.05 ). The copy count of EBV DNA in the blood of patients from the EBER-positive group was higher, and the prognosis was worse ( P < 0.05 ). Clinical manifestations were more severe in the EBER-positive group. Endoscopic, histopathological, and biochemical findings were also more serious in this group of patients. The findings point to the importance of assessing the EBER expression in patients with intestinal ulcers of various etiology. EBER positivity should be viewed as a diagnostic marker of more severe condition requiring more aggressive treatment.

The levels of ALT, AST, LDH, TG, SF, D-Dimer and the plasma EBV DNA load of EBV-HLH patients were significantly higher than those of EBV-IM patients. The absolute values of CD3+, CD4+, CD8+, NK, and CD3-CD19+ cells and IgA and IgM levels of EBV-HLH patients were significantly lower than those of EBV-IM patients. The plasma EBV DNA load was positively correlated with the PT, TT, α-HBDH, AST, LDH, CK, Scr, BUN, UA, TG, and CRP levels in EBV-HLH patients, and the plasma EBV DNA load was positively correlated with the D-Dimer level in the EBV-IM patients. Among the 10 different potential markers, at the cut-off point of 1721.500 µg/L, the sensitivity and specificity of D-Dimer was 88.90% and 90.20%, respectively.Conclusion: The D-Dimer level may be a good prognostic indicator of EBV-HLH caused by EBV.

We examined whether Epstein–Barr virus (EBV) infection plays a role in cervical carcinogenesis in Korean women. EBV infection was examined using polymerase chain reaction (PCR) with two different primer pairs flanking the BamHI “W” fragment of EBV and by EBV-encoded small RNAs (EBER) in situ hybridization in various histologic types of cervical cancer, including 17 cases of squamous cell carcinoma, 36 cases of adenocarcinoma, and 3 cases of small-cell carcinoma. We also evaluated 20 cases of cervical intraepithelial neoplasia and 20 cases of normal uterine cervix. One case of squamous cell carcinoma and three cases of cervical intraepithelial neoplasia were positive for EBV DNA using PCR, but EBER in situ hybridization analysis showed that none of the PCR-positive cases expressed EBER. EBV DNA was not found using PCR in any of the 20 normal uterine cervices. From our results, EBV infection does not seem to play a role in cervical carcinogenesis in Korean women.
