Abstract
Sequence analyses highlight a massive peptide sharing between immunoreactive Epstein-Barr virus (EBV) epitopes and human proteins that—when mutated, deficient or improperly functioning—associate with tumorigenesis, diabetes, lupus, multiple sclerosis, rheumatoid arthritis, and immunodeficiencies, among others. Peptide commonality appears to be the molecular platform capable of linking EBV infection to the vast EBV-associated diseasome via cross-reactivity and questions the hypothesis of the “negative selection” of self-reactive lymphocytes. Of utmost importance, this study warns that using entire antigens in anti-EBV immunotherapies can associate with autoimmune manifestations and further supports the concept of peptide uniqueness for designing safe and effective anti-EBV immunotherapies.

Abstract
Angiopoietin/tyrosine protein kinase receptor Tie-2 signaling in endothelial cells plays an essential role in angiogenesis and wound healing. Angiopoietin-1 (Ang-1) is crucial for blood vessel maturation while angiopoietin-2 (Ang-2), in collaboration with vascular endothelial growth factor (VEGF), initiates angiogenesis by destabilizing existing blood vessels. In healthy people, the Ang-1 level is sustained while Ang-2 expression is restricted. In cancer patients, Ang-2 level is elevated, which correlates with poor prognosis. Ang-2 not only drives tumor angiogenesis but also attracts infiltration of myeloid cells. The latter rapidly differentiate into tumor stromal cells that foster tumor angiogenesis and progression, and weaken the host’s anti-tumor immunity. Moreover, through integrin signaling, Ang-2 induces expression of matrix metallopeptidases (MMPs) to promote tumor cell invasion and metastasis. Many oncogenic viruses induce expression of Ang-2 to promote development of neoplasia associated with viral infection. Multiple Ang-2 inhibitors exhibit remarkable anti-tumor activities, further highlighting the importance of Ang-2 in cancer development.

Noncoding RNA 2018; 4:ncrna4040024. [PMID: 30261651 PMCID: PMC6315926 DOI: 10.3390/ncrna4040024] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2018] [Revised: 09/17/2018] [Accepted: 09/18/2018] [Indexed: 12/17/2022] Open
Abstract
Advances in next-generation sequencing have facilitated the discovery of a multitude of long non-coding RNAs (lncRNAs) with pleiotropic functions in cellular processes, disease, and viral pathogenesis. It came as no surprise when viruses were also revealed to transcribe their own lncRNAs. Among them, gammaherpesviruses, one of the three subfamilies of the Herpesviridae, code their largest number. These structurally and functionally intricate non-coding (nc) transcripts modulate cellular and viral gene expression to maintain viral latency or prompt lytic reactivation. These lncRNAs allow for the virus to escape cytosolic surveillance, sequester, and re-localize essential cellular factors and modulate the cell cycle and proliferation. Some viral lncRNAs act as “messenger molecules”, transferring information about viral infection to neighboring cells. This broad range of lncRNA functions is achieved through lncRNA structure-mediated interactions with effector molecules of viral and host origin, including other RNAs, proteins and DNAs. In this review, we discuss examples of gammaherpesvirus-encoded lncRNAs, emphasize their unique structural attributes, and link them to viral life cycle, pathogenesis, and disease progression. We will address their potential as novel targets for drug discovery and propose future directions to explore lncRNA structure and function relationship.

Abstract
We report a biosensing platform for viral load measurement through electrical sensing of viruses on a flexible plastic microchip with printed electrodes. Point-of-care (POC) viral load measurement is of paramount importance with significant impact on a broad range of applications, including infectious disease diagnostics and treatment monitoring specifically in resource-constrained settings. Here, we present a broadly applicable and inexpensive biosensing technology for accurate quantification of bioagents, including viruses in biological samples, such as plasma and artificial saliva, at clinically relevant concentrations. Our microchip fabrication is simple and mass-producible as we print microelectrodes on flexible plastic substrates using conductive inks. We evaluated the microchip technology by detecting and quantifying multiple Human Immunodeficiency Virus (HIV) subtypes (A, B, C, D, E, G, and panel), Epstein-Barr Virus (EBV), and Kaposi's Sarcoma-associated Herpes Virus (KSHV) in a fingerprick volume (50 µL) of PBS, plasma, and artificial saliva samples for a broad range of virus concentrations between 10(2) copies/mL and 10(7) copies/mL. We have also evaluated the microchip platform with discarded, de-identified HIV-infected patient samples by comparing our microchip viral load measurement results with reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) as the gold standard method using Bland-Altman Analysis.

Abstract
UNLABELLED Gammaherpesviruses display tropism for B cells and, like all known herpesviruses, exhibit distinct lytic and latent life cycles. One well-established observation among members of the gammaherpesvirus family is the link between viral reactivation from latently infected B cells and plasma cell differentiation. Importantly, a number of studies have identified a potential role for a CREB/ATF family member, X-box binding protein 1 (XBP-1), in trans-activating the immediate early BZLF-1 or BRLF1/gene 50 promoters of Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), respectively. XBP-1 is required for the unfolded protein response and has been identified as a critical transcription factor in plasma cells. Here, we demonstrate that XBP-1 is capable of trans-activating the murine gammaherpesvirus 68 (MHV68) RTA promoter in vitro, consistent with previous observations for EBV and KSHV. However, we show that in vivo there does not appear to be a requirement for XBP-1 expression in B cells for virus reactivation. The MHV68 M2 gene product under some experimental conditions plays an important role in virus reactivation from B cells. M2 has been shown to drive B cell differentiation to plasma cells, as well as interleukin-10 (IL-10) production, both of which are dependent on M2 induction of interferon regulatory factor 4 (IRF4) expression. IRF4 is required for plasma cell differentiation, and consistent with a role for plasma cells in MHV68 reactivation from B cells, we show that IRF4 expression in B cells is required for efficient reactivation of MHV68 from splenocytes. Thus, the latter analyses are consistent with previous studies linking plasma cell differentiation to MHV68 reactivation from B cells. The apparent independence of MHV68 reactivation from XBP-1 expression in plasma cells may reflect redundancy among CREB/ATF family members or the involvement of other plasma cell-specific transcription factors. Regardless, these findings underscore the importance of in vivo studies in assessing the relevance of observations made in tissue culture models. IMPORTANCE All known herpesviruses establish a chronic infection of their respective host, persisting for the life of the individual. A critical feature of these viruses is their ability to reactivate from a quiescent form of infection (latency) and generate progeny virus. In the case of gammaherpesviruses, which are associated with the development of lymphoproliferative disorders, including lymphomas, reactivation from latently infected B lymphocytes occurs upon terminal differentiation of these cells to plasma cells-the cell type that produces antibodies. A number of studies have linked a plasma cell transcription factor, XBP-1, to the induction of gammaherpesvirus reactivation, and we show here that indeed in tissue culture models this cellular transcription factor can trigger expression of the murine gammaherpesvirus gene involved in driving virus reactivation. However, surprisingly, when we examined the role of XBP-1 in the setting of infection of mice-using mice that lack a functional XBP-1 gene in B cells-we failed to observe a role for XBP-1 in virus reactivation. However, we show that another cellular factor essential for plasma cell differentiation, IRF4, is critical for virus reactivation. Thus, these studies point out the importance of studies in animal models to validate findings from studies carried out in cell lines passaged in vitro.

Abstract
Infection with the Epstein-Barr virus (EBV) can lead to a number of human diseases including Hodgkin's and Burkitt's lymphomas. The development of these EBV-linked diseases is associated with the presence of nine viral latent proteins, including the nuclear antigen 2 (EBNA2). The EBNA2 protein plays a crucial role in EBV infection through its ability to activate transcription of both host and viral genes. As part of this function, EBNA2 associates with several host transcriptional regulatory proteins, including the Tfb1/p62 (yeast/human) subunit of the general transcription factor IIH (TFIIH) and the histone acetyltransferase CBP(CREB-binding protein)/p300, through interactions with its C-terminal transactivation domain (TAD). In this manuscript, we examine the interaction of the acidic TAD of EBNA2 (residues 431-487) with the Tfb1/p62 subunit of TFIIH and CBP/p300 using nuclear magnetic resonance (NMR) spectroscopy, isothermal titration calorimeter (ITC) and transactivation studies in yeast. NMR studies show that the TAD of EBNA2 binds to the pleckstrin homology (PH) domain of Tfb1 (Tfb1PH) and that residues 448-471 (EBNA2₄₄₈₋₄₇₁) are necessary and sufficient for this interaction. NMR structural characterization of a Tfb1PH-EBNA2₄₄₈₋₄₇₁ complex demonstrates that the intrinsically disordered TAD of EBNA2 forms a 9-residue α-helix in complex with Tfb1PH. Within this helix, three hydrophobic amino acids (Trp458, Ile461 and Phe462) make a series of important interactions with Tfb1PH and their importance is validated in ITC and transactivation studies using mutants of EBNA2. In addition, NMR studies indicate that the same region of EBNA2 is also required for binding to the KIX domain of CBP/p300. This study provides an atomic level description of interactions involving the TAD of EBNA2 with target host proteins. In addition, comparison of the Tfb1PH-EBNA2₄₄₈₋₄₇₁ complex with structures of the TAD of p53 and VP16 bound to Tfb1PH highlights the versatility of intrinsically disordered acidic TADs in recognizing common target host proteins.

Abstract
The Epstein-Barr nuclear antigen 3C (EBNA3C), one of the essential latent antigens for Epstein-Barr virus (EBV)-induced immortalization of primary human B lymphocytes in vitro, has been implicated in regulating cell proliferation and anti-apoptosis via interaction with several cellular and viral factors. Gemin3 (also named DDX20 or DP103) is a member of DEAD RNA helicase family which exhibits diverse cellular functions including DNA transcription, recombination and repair, and RNA metabolism. Gemin3 was initially identified as a binding partner to EBNA2 and EBNA3C. However, the mechanism by which EBNA3C regulates Gemin3 function remains unclear. Here, we report that EBNA3C directly interacts with Gemin3 through its C-terminal domains. This interaction results in increased stability of Gemin3 and its accumulation in both B lymphoma cells and EBV transformed lymphoblastoid cell lines (LCLs). Moreover, EBNA3C promotes formation of a complex with p53 and Gemin3 which blocks the DNA-binding affinity of p53. Small hairpin RNA based knockdown of Gemin3 in B lymphoma or LCL cells remarkably attenuates the ability of EBNA3C to inhibit the transcription activity of p53 on its downstream genes p21 and Bax, as well as apoptosis. These findings provide the first evidence that Gemin3 may be a common target of oncogenic viruses for driving cell proliferation and anti-apoptotic activities. Gemin3 (DDX20 or DP103) is a member of the DEAD-box family of RNA helicases involved in various cellular processes including DNA transcription and RNA processing. The Epstein-Barr virus (EBV) encoded nuclear antigen 3C (EBNA3C) is essential for EBV-induced immortalization of primary human B-lymphocytes in vitro. In this study, we discovered that Gemin3 directly binds to the tumor suppressor p53, and acts as a negative regulator blocking p53 functions. Importantly, EBNA3C induces Gemin3 accumulation and enhances the formation of the complex of Gemin3 and p53 in EBV- transformed primary human B lymphocytes. Remarkably, inhibition of Gemin3 production leads to cell death of B lymphoma cells, particularly EBNA3C positive cells. This is the first evidence which shows that Gemin3 directly impairs p53 function in EBV positive cells, and that Gemin3 could be a potential target for EBV-associated cancer therapy.

Abstract
Epstein-Barr virus nuclear antigen 2 (EBNA2) regulation of transcription through the cell transcription factor RBPJ is essential for resting B-lymphocyte (RBL) conversion to immortal lymphoblast cell lines (LCLs). ChIP-seq of EBNA2 and RBPJ sites in LCL DNA found EBNA2 at 5,151 and RBPJ at 10,529 sites. EBNA2 sites were enriched for RBPJ (78%), early B-cell factor (EBF, 39%), RUNX (43%), ETS (39%), NFκB (22%), and PU.1 (22%) motifs. These motif associations were confirmed by LCL RBPJ ChIP-seq finding 72% RBPJ occupancy and Encyclopedia Of DNA Elements LCL ChIP-seq finding EBF, NFκB RELA, and PU.1 at 54%, 31%, and 17% of EBNA2 sites. EBNA2 and RBPJ were predominantly at intergene and intron sites and only 14% at promoter sites. K-means clustering of EBNA2 site transcription factors identified RELA-ETS, EBF-RUNX, EBF, ETS, RBPJ, and repressive RUNX clusters, which ranked from highest to lowest in H3K4me1 signals and nucleosome depletion, indicative of active chromatin. Surprisingly, although quantitatively less, the same genome sites in RBLs exhibited similar high-level H3K4me1 signals and nucleosome depletion. The EBV genome also had an LMP1 promoter EBF site, which proved critical for EBNA2 activation. LCL HiC data mapped intergenic EBNA2 sites to EBNA2 up-regulated genes. FISH and chromatin conformation capture linked EBNA2/RBPJ enhancers 428 kb 5' of MYC to MYC. These data indicate that EBNA2 evolved to target RBL H3K4me1 modified, nucleosome-depleted, nonpromoter sites to drive B-lymphocyte proliferation in primary human infection. The primed RBL program likely supports antigen-induced proliferation.

Abstract
Nm23-H1 was discovered as the first metastasis suppressor gene about 20 years ago. Since then, extensive work has contributed to understanding its role in various cellular signaling pathways. Its association with a range of human cancers as well as its ability to regulate cell cycle and suppress metastasis has been explored. We have determined that the EBV-encoded nuclear antigens, EBNA3C and EBNA1, required for EBV-mediated lymphoproliferation and for maintenance EBV genome extrachromosomally in dividing mammalian cells, respectively, target and disrupt the physiological role of Nm23-H1 in the context of cell proliferation and cell migration. This review will focus on the interaction of Nm23-H1 with the Epstein-Barr virus nuclear antigens, EBNA3C and EBNA1 and the functional significance of this interaction as it relates to EBV pathogenesis.

Abstract
BRCA1-associated protein 2 (BRAP2) is known to interact with the kinase suppressor of Ras 1 (KSR1), inhibiting the ERK signal transduction cascade. This study found that an Epstein-Barr virus (EBV) immediate-early protein, Rta, is a binding partner of BRAP2 in yeast and confirmed the binding in vitro by a glutathione S-transferase pull-down assay and in vivo by co-immunoprecipitation in 293(maxi-EBV) cells. Binding studies also showed that Rta and KSR1 interacted with the C-terminal 202 aa region in BRAP2. Additionally, Rta appeared to prevent the binding of KSR1 to BRAP2, activating the ERK signal transduction pathway and the transcription of an EBV immediate-early gene, BZLF1. Activation of the ERK signal transduction pathway by Rta may be critical for the maintenance of the lytic state of EBV.

Abstract
Infectious mononucleosis (IM) has been associated with an increased risk of Hodgkin lymphoma (HL), implicating a role for Epstein-Barr virus (EBV) in HL development. Although essential to the understanding of the association, it has remained uncertain if the relationship is restricted to the EBV-positive subset of HL. We collected information on mononucleosis history and childhood socioenvironmental characteristics in a population-based study of 586 patients with classic HL and 3,187 controls in Denmark and Sweden. Tumor EBV status was established for 499 cases by immunohistochemistry and in situ hybridization techniques. Odds ratios (OR) for the relationship between HL risk and mononucleosis and other risk factors were estimated by logistic regression for HL in younger (18-44 years) and older (45-74 years) adults, overall and by tumor EBV status. All analyses were adjusted for country-specific measures of maternal education and mononucleosis history. IM was associated with an increased risk of EBV-positive [OR, 3.23; 95% confidence interval (95% CI) 1.89-5.55] but not EBV-negative HL (OR, 1.35; 95% CI, 0.86-2.14). Risk of EBV-positive HL varied with time since IM and was particularly pronounced in younger adults (OR, 3.96; 95% CI, 2.19-7.18). IM-associated lymphomas occurred with a median of 2.9 years (1.8-4.9 years) after infection. The EBV specificity of the IM association was corroborated by a case-case comparison of IM history between younger adult EBV-positive and EBV-negative HL patients (OR(IM EBV+ HL versus EBV- HL), 2.68; 95% CI, 1.40-5.12). We found further evidence that IM is associated only with EBV-positive HL. This finding is compatible with the notion that EBV-positive and EBV-negative HL may have different etiologies.

Abstract
Malignancies associated with latent Epstein-Barr virus (EBV) are resistant to nucleoside-type antiviral agents because the viral enzyme target of these antiviral drugs, thymidine kinase (TK), is not expressed. Short-chain fatty acids, such as butyrate, induce EBV-TK expression in latently infected B cells. As butyrate has been shown to sensitize EBV(+) lymphoma cells in vitro to apoptosis induced by ganciclovir, arginine butyrate in combination with ganciclovir was administered in 15 patients with refractory EBV(+) lymphoid malignancies to evaluate the drug combination for toxicity, pharmacokinetics, and clinical responses. Ganciclovir was administered twice daily at standard doses, and arginine butyrate was administered by continuous infusion in an intrapatient dose escalation, from 500 mg/(kg/day) escalating to 2000 mg/(kg/day), as tolerated, for a 21-day cycle. The MTD for arginine butyrate in combination with ganciclovir was established as 1000 mg/(kg/day). Ten of 15 patients showed significant antitumor responses, with 4 CRs and 6 PRs within one treatment cycle. Complications from rapid tumor lysis occurred in 3 patients. Reversible somnolence or stupor occurred in 3 patients at arginine butyrate doses of greater than 1000 mg/(kg/day). The combination of arginine butyrate and ganciclovir was reasonably well-tolerated and appears to have significant biologic activity in vivo in EBV(+) lymphoid malignancies which are refractory to other regimens.

Abstract
EBER 1, a small noncoding viral RNA abundantly expressed in all cells transformed by Epstein-Barr virus (EBV), has been shown to associate with the human ribosomal protein L22. Here we present in vitro binding studies using purified RNAs and recombinant proteins. Electrophoretic mobility-shift assays (EMSAs) show that recombinant L22 (rL22) and maltose-binding protein (MBP)-tagged L22 protein bind EBER 1 in vitro, both forming three specific protein-dependent mobility shifts. Use of a mixture of rL22 and MBP-L22 indicates that these three shifts contain one, two, or three L22 proteins per EBER 1 molecule. EMSAs performed with EBER 1 deletion constructs and EBER 1 stem-loops inserted into a nonbinding RNA, HSUR 3, identify stem-loops I, III, and IV as L22 binding sites. The existence of multiple L22 binding sites on EBER 1 inside cells is demonstrated by in vivo UV cross-linking. Our results are discussed with respect to the function of EBER 1 in EBV-infected human B cells.

Abstract
The close relationship between Epstein-Barr virus (EBV) and nasal T-cell lymphoma (NTL) has frequently been reported. However, the status of the infection, either lytic or latent, is obscure. This study involved 16 patients with NTL. Phenotypes of lymphoma cells were examined by immunohistochemical staining using CD3, CD4, CD8, CD20 and CD45RO monoclonal antibodies. EBV-encoded small nuclear RNA (EBER)-1 and EBV NotI tandem repeat region were detected by reverse transcription, using a rapid (< or = 60 min) in situ hybridization technique. Tumor cells expressed at least one T-cell marker, such as CD3, CD4, CD8 and CD45RO. CD20 was not detected in any of the cases. EBER-1 was identified in all cases; no Notl tandem DNA repeat was demonstrated. All cases demonstrated a T-cell phenotype. These data suggest that NTL is associated with EBV infection in the latent phase.

Abstract
Epidemiologic and clinico-pathologic features of Hodgkin's disease suggest that an infectious agent may be involved in the pathogenesis of this puzzling disorder. Recently accumulated data provide direct evidence supporting a causal role of Epstein-Barr virus in a significant proportion of cases. In addition to allowing a better understanding of the complex pathogenesis of Hodgkin's disease, these virological advances, briefly reviewed herein, also constitute an important basis for the development of new therapeutic strategies.

Abstract
Epstein-Barr virus (EBV) is detected in Hodgkin and Reed-Sternberg (HRS) cells in up to 50% of patients with Hodgkin's disease (HD). HD patients have been reported to express high serum titers against EBV antigens, even prior to the diagnosis of HD. Patients with high serum titers have a poorer prognosis. The aim of this study was to examine the relationship between the presence of EBV in HRS cells and the antibody titers reactive with different EBV antigens. Frozen serum and histopathological tissues were available from 107 untreated HD patients diagnosed between 1979 and 1991. The presence of EBV in the HRS cells was evaluated with immunohistochemistry directed against the LMP-1 antigen and/or with in situ hybridization of EBER-1. Analyses were performed of serum titers against early antigen (EA), diffuse (IgA and IgG) and restricted (IgG), virus-capsid antigen (VCA) (IgA and IgG), and EBV-encoded nuclear antigens (EBNA, EBNA 1, EBNA 2A, EBNA 2B, EBNA 6). EBV was detected in 27/107 (25%) tumor specimens, with a higher proportion in the MC group 8/13 (62%) (p < 0.01). IgG VCA and EBNA were detected in 99/107 (93%), evidence of a previous EBV infection. There were no significant relationships between antibody titers reactive with different EBV antigens and detectable EBV in HRS cells. Furthermore, there did not appear to be any relationship between EBV serology or the presence of EBV in HRS cells and clinical outcome. The role of EBV in the development of HD, especially its relationship to the immunological response, remains unclear.

Abstract
Since Hodgkin's disease (HD) is an heterogeneous condition with diverse histological and epidemiological subgroups, it seemed worthwhile to investigate the Argentine pediatric pattern. Moreover, the presence of Epstein Barr virus (EBV) infection occurs at different ages depending on the development status of the country. Thus, it was interesting to assess the relation between EBV and HD in the Argentine pediatric population. The age distribution profile of our pediatric HD patients showed a peak in early childhood which declined towards adolescence, closely resembling EBV infection pattern. Male:female ratio of the studied population was 3.2:1 and the histological subtype distribution disclosed that mixed cellularity HD (MCHD) was the most common, an epidemiological profile shared with other developing countries. Fifty percent of assessed HD cases were associated with EBV, showing a significantly higher prevalence in the 3-6 years-old group, indicating a non-random distribution. EBV was also present in most of MCHD cases and in some nodular lymphocyte predominance HD (nLPHD) but entirely absent in nodular sclerosis HD (NSHD). Both EBV subtypes, namely EBV-1 and EBV-2, were detected in studied HD cases. EBV-HD association in the Argentine pediatric population reveals typical epidemiological features indicating EBV as the aetiologic agent or, alternatively as a cofactor in a considerable percentage of such HD cases.

Abstract
PURPOSE We described for the first time a patient with long-lasting, extremely high serum antibody titer against Epstein-Barr virus (EBV) viral capsid antigen and early antigen without clinical symptoms suggestive of active EBV infection; the patient finally developed Hodgkin disease (HD) after 7 years of follow-up. PATIENT AND METHODS High serum EBV antibody titers were noted at 2 years of age. Immunological evaluation was performed at the age of 7 years. EBV-specific cytotoxic T-lymphocyte activity was normal. None of the other results showed any significant abnormalities except for the abnormal antibody titers against EBV-associated antigens. RESULTS The patient developed HD at the age of 9 years. In addition, EBV genomes were found in the nuclei of Hodgkin and Reed-Sternberg cells in the lymph node. CONCLUSIONS This case suggests that (a) a patient with extremely high serum antibody titers against EBV-associated antigens may develop HD after a prolonged period, even though no clinical symptom suggestive of active EBV infection is observed; (b) EBV may play an important role in the occurrence of HD.

Abstract
BACKGROUND The incidence of Hodgkin's disease (HD) in Korea and other Asian countries is much lower than in western countries and its association with the Epstein-Barr virus has not been well characterized. METHODS We evaluated the clinical, morphologic, and immunohistochemical features of 87 patients with Hodgkin's disease and also analyzed patients for Epstein-Barr virus (EBV) using in situ hybridization for EBV DNA, RNA, and latent membrane protein (LMP1). RESULTS There were 68 males and 19 females, with a mean age of 38 years. Mixed cellularity was the most prevalent subtype. Expression of EBV RNA (EBER:EBV-encoded RNA) was detected in 60 of 87 cases (69%): 1 of 1 (100%) with lymphocyte predominance, nodular; 4 of 7 (57%) with lymphocyte predominance, diffuse; 10 of 17 (59%) with nodular sclerosis; 38 of 51 (75%) with mixed cellularity; and 7 of 11 (64%) with lymphocyte depletion. Positivity was higher in advanced clinical stages; 4 of 7 patients (57%) with Stage I; 6 of 12 patients (50%) with Stage II: 7 of 9 patients (75%) with Stage III; and 5 of 5 patients (100%) with Stage IV HD EBV DNA was detected in 9 of 25 cases tested (36%). LMP1 was seen in 39 of 87 cases (45%). EBER and LMP1 positivity were higher in children and older adults than in adults aged between 15-50 years. Immediate early mRNAs (BHLF:Bam H-fragment, lower strand frame) was seen in a single patient. CONCLUSIONS HD in Korea showed a high incidence of mixed cellularity subtype and a high prevalence of EBV. EBV was detected in all subtypes, including a case of nodular lymphocytic predominance, and in all age groups, and showed correlation with mixed cellularity subtype and higher clinical stage. The expression of EBER and LMP were more frequently seen in children and older adults, suggesting a lowered immune surveillance in those age groups or a different pathophysiology of HD among different age groups.

Abstract
Like Burkitt's lymphoma, the strength of association of Epstein-Barr virus (EBV) with Hodgkin's disease occurring in different populations and clinical settings is highly variable, being 30% to 50% in Western countries, nearly 100% in Third World countries like Peru and Honduras, and nearly 100% in patients seropositive for human immunodeficiency virus. Data on the Oriental populations are very limited. Therefore, the current study was performed on the Chinese population of Hong Kong, where the incidence of Hodgkin's disease is low and EBV seroconversion occurs early in life. Twenty-three consecutive samples of Hodgkin's disease collected from 18 male and five female patients over a 12-year period were studied. The first age peak occurred in the second decade of life, and the second peak in the seventh decade. Using the sensitive and specific EBV-encoded RNAs (EBERs) in situ localization technique, positive labeling of the Reed-Sternberg cells and their variants was detected in five of five samples (100%) of mixed cellularity, nine of 16 samples (56%) of nodular sclerosing, one of one sample (100%) of lymphocyte depleted, and none of one sample (0%) of nodular lymphocyte predominant Hodgkin's disease. Further analysis of the data by age group yielded the following results: four of five (80%) for age younger than 15 years, three of nine (33%) for age 15 to 49, and eight of nine (89%) for age 50 or higher, confirming the reported strong association of EBV with Hodgkin's disease at the extremes of life. The overall positivity rate was 65%, which was intermediate between that reported in the Western populations and that in the Third World countries. These findings can be explained by the epidemiological pattern of Hodgkin's disease in Hong Kong, in which the first age peak is left-shifted to a younger age compared with that of Western populations (but not as early as that observed in Third World countries), moving the peak toward an age bracket in which Hodgkin's disease shows stronger association with EBV.

Abstract
We assessed the relationship of Epstein-Barr virus (EBV) serology to the presence or absence of EBV genome in 39 cases of Hodgkin's disease (HD). Biopsies from patients included in 2 previous published studies, 1 involving patients from the United States (eastern Massachusetts) and 1 from Denmark, were evaluated for EBV (EBER-1) and latent membrane protein (LMP-1). The presence of EBV in Reed-Sternberg cells in the biopsies correlated with the histologic subtype of HD (mixed cellularity and lymphocyte depletion) but not with IgG antibody titers against the viral capsid antigen (VCA). These data suggest that, unlike Burkitt's lymphoma, the IgG antibody against VCA is not predictive of the presence or absence of EBV in Reed-Sternberg cells in HD. The predictive value of other antibodies should be evaluated.

Abstract
BACKGROUND Epstein-Barr virus- (EBV) related DNA and RNA can be found in tissues involved with Hodgkin's disease, specifically in the Reed-Sternberg cells. These cells also express the membrane antigens LMP1 and LMP 2A and 2B. Studies in normal individuals indicate that cellular immunity against LMP2 was frequently mediated through human leukocyte antigen (HLA) A2, whereas responses to LMP1 appeared to be relatively infrequent. Assuming that LMP2-positive Reed-Sternberg cells would be sensitive to a CD8-positive cellular immune response, the hypothesis can be made that EBV-positive Hodgkin's disease should be more common in individuals not expressing HLA A2. To test this hypothesis, the authors have studied the frequency of HLA A2 in EBV-positive versus EBV-negative patients with Hodgkin's disease. METHODS All 72 patients diagnosed with Hodgkin's disease in Northern and Central Alberta, Canada, during 1990 and 1991 were studied. A nonisotopic in situ hybridization method with an oligonucleotide probe specific for EBER 1 and 2 was used. In addition, sections were stained for the EBV-latent protein LMP1, HLA A2, and a monomorphic HLA class I determinant and beta 2-microglobulin. RESULTS EBER-positive Reed-Sternberg cells were found in 26% of the patients. The percentage of positive patients was 86% in mixed cellularity, 13% in nodular sclerosis, and 0% in lymphocyte predominance. The number of those who were HLA-A2 positive was approximately 50% in the EBV-positive and -negative patients. CONCLUSIONS Therefore, no correlation between HLA A2 expression and presence or absence of EBV in the R-S cells of Hodgkin's disease was identified.

Abstract
Epstein-Barr virus (EBV) can be detected in Hodgkin and Reed-Sternberg (HRS) cells in about one-half of cases of Hodgkin's disease (HD) in Western countries. To determine whether EBV is also associated with HD in a developing country such as China, we studied paraffin sections from 28 Chinese cases of HD for expression of latent membrane protein-I (LMP-I) and EBV-encoded small RNA (EBER-I), using immuno-histology and RNA/RNA in situ hybridization respectively. The cases were selected from a large series of Chinese lymphomas following histological and immunophenotypical revision. EBV gene expression was found in HRS cells in 17/28 cases, and was related to histological sub-type, being present in 10/11 of mixed cellularity, 6/14 nodular sclerosis, 0/1 lymphocytic predominance, 0/1 lymphocytic depletion, and 1/1 unclassified HD. The 2 methods for detecting EBV gene expression gave similar results, except in one case of nodular sclerosis, in which HRS cells were negative for EBER-I, but weakly positive for LMP-I. In 5/12 cases with EBER-negative HRS cells, rare small or medium-sized lymphocytes expressed EBER-I but not LMP-I. These results suggest that (i) Chinese HD is frequently associated with EBV; (ii) the proportional frequency and sub-type distribution of EBV-positive HD are similar in China and in the West; (iii) both LMP-I immunohistology and EBER in situ hybridization reliably detect EBV in HRS cells in routine biopsies, but the former is simpler and less resource-consuming to perform.

Abstract
BACKGROUND The first cases of Hodgkin's disease (HD) associated with HIV infection were reported in 1984. Since then, short series of seropositive patients suffering from HD have been published. In order to identify the characteristics, treatment response and outcome of HIV-associated Hodgkin's disease (HIV-HD), the data of HIV-HD patients recorded between 1987 and 1989 were analysed and compared with those of primary HD patient and with those of HIV-associated non-Hodgkin's lymphoma (HIV-NHL), registered during the same period. PATIENTS AND METHODS The 45 cases of HD collected by the French registry of HIV-associated tumors between January 1987 and December 1989 were included in this study. All patients were clinically staged according to the Ann Arbor system. To compare HIV-HD characteristics with those of primary HD, we used a cohort of 407 patients with clinical stages (CS) IA to IVB, who were enrolled between September 1981 and August 1988 in a multicentric clinical trial. To identify the relationship between HIV-HD and the course of HIV infection we studied, when available, the routes of infection, initial CD4 cell count at the moment of HD diagnostic as well as the CDC class of HIV infection and compared these data with the same parameters observed in 142 HIV-NHL enrolled in the registry during the same period. RESULTS HIV-HD is characterized by an increase in mixed-cellularity histology (49%), with a predominance of advanced stages (75%) and B symptoms (80%). A unique observation is made regarding mediastinal involvement, present in only 13% of HIV-HD (71% in primary HD). The HIV-HD/HIV-NHL ratio was significantly higher in intravenous drug abusers than in male homosexuals. Median CD4 cell count was 306/microliters at HIV-HD diagnosis, and only 11% of the cases were preceded by an AIDS manifestation. With standard therapy, 79% of the patients achieved complete remission, but hematological and infectious complications were very frequent. The progression to AIDS rate was 94% at two years and opportunistic infections were the most frequent cause of death. Overall two-year survival was 41% with 71% for patients with initial CD 4 cell counts higher than 300/microliter and 0% for those with CD4 cell counts lower than 300/microliter (P < 0.01). CONCLUSION HIV-HD has a particular clinico-pathological profile when compared to primary HD, with a predominance of mixed-cellularity type, a high frequency of advanced stages and a high proportion of patients without mediastinal involvement. Moreover, HIV-HD seems to occur preferentially in the group of subjects infected by needle sharing. Standard HD therapy seems to be efficient but excessively toxic.

Abstract
Epstein-Barr virus (EBV) is associated with a number of different human tumors and appears to play different pathogenetic roles in each case. Thus, immunoblastic B cell lymphomas of the immunosuppressed display the full pattern of EBV latent gene expression (expressing Epstein-Barr nuclear antigen [EBNA]1, 2, 3A, 3B, 3C, and -LP, and latent membrane protein [LMP]1, 2A, and 2B), just as do B lymphoblastoid cell lines transformed by the virus in vitro. In contrast, those EBV-associated tumors with a more complex, multistep pathogenesis show more restricted patterns of viral gene expression, limited in Burkitt's lymphoma to EBNA1 only and in nasopharyngeal carcinoma (NPC) to EBNA1 and LMP1, 2A, and 2B. Recent evidence has implicated EBV in the pathogenesis of another lymphoid tumor, Hodgkin's disease (HD), where the malignant Hodgkin's and Reed-Sternberg (HRS) cells are EBV genome positive in up to 50% of cases. Here we extend preliminary results on viral gene expression in HRS cells by adopting polymerase chain reaction-based and in situ hybridization assays capable of detecting specific EBV latent transcripts diagnostic of the different possible forms of EBV latency. We show that the transcriptional program of the virus in HRS cells is similar to that seen in NPC in several respects: (a) selective expression of EBNA1 mRNA from the BamHI F promoter; (b) downregulation of the BamHI C and W promoters and their associated EBNA mRNAs; (c) expression of LMP1 and, in most cases, LMP2A and 2B transcripts; and (d) expression of the "rightward-running" BamHI A transcripts once thought to be unique to NPC. This form of latency, consistently detected in EBV-positive HD irrespective of histological subtype, implies an active role for the virus in the pathogenesis of HD and also suggests that the tumor may remain sensitive to at least certain facets of the EBV-induced cytotoxic T cell response.

Abstract
Epstein-Barr virus (EBV) latent membrane protein 1 (LMP 1) is expressed in Hodgkin and Reed-Sternberg (HRS) cells in about one half of Hodgkin's disease (HD) cases. In vitro, LMP 1 induces B-cell expression of CD23 antigen, ICAM-1 and LFA-3. To evaluate the influence of LMP 1 on the expression of these molecules in HRS cells in vivo, we performed a quantitative frozen section immunohistological study comparing the numerical density (cells per unit area) of HRS cells expressing the CD23 antigen, ICAM-1 and LFA-3 in 14 LMP 1-positive and 13 LMP 1-negative HD cases. CD23 antigen was demonstrated in HRS cells in five LMP 1-positive and three LMP 1-negative cases (not significant). The relative density of HRS cells tended to be lower in the LMP 1-positive than in the LMP 1-negative cases, but this did not reach significance (0.2 > 2p > 0.1). All recognizable HRS cells expressed ICAM-1 and LFA-3 irrespective of LMP 1 status. We conclude that expression of CD23 antigen and LMP 1 are not coordinated in HD. Although LMP 1 may have some influence on CD23 antigen expression, it is unlikely that the latter is of importance in the putative EBV induced growth transformation of HRS cells in vivo.

Abstract
The present study was performed to clarify the reported inconsistencies regarding the frequency of the association of Epstein-Barr virus (EBV) and Hodgkin's disease (HD). Biopsies from 102 patients with HD were screened for the presence of EBV-encoded small nuclear RNA (EBER) and latent membrane protein (LMP) by using a non-isotopic in situ hybridization (ISH) and immunohistology (IH), respectively. The results were additionally compared with those obtained by polymerase chain reaction (PCR) for EBV-DNA detection. EBV was detected by EBER-ISH in 67% of the HD cases and in 25% of the control group cases consisting of normal lymph nodes. The results of PCR performed on cases with amplifiable DNA were overall congruent with those obtained by EBER-ISH. With respect to the cellular localization of EBV, four categories of HD could be established: (a) cases with EBV-infected tumour cells (42/102), (b) cases with additional infection of bystander cells (4/102); (c) cases with EBV infection restricted to non-malignant bystander cells (23/102); and (d) cases with neither EBV-infected tumour cells nor bystander cells (33/102). LMP expression was detectable only in the neoplastic cell population of those cases with EBER-positive tumour cells, suggesting a frequent involvement of EBV in the pathogenesis of HD.

Abstract
The most recent sophisticated investigations have provided new and revealing, but also contradictory and controversial information on the biological nature and the cellular origin of Hodgkin and Reed-Sternberg cells (H-RS). Immunophenotypic analyses have shown variable phenotypic antigen expression; but, on balance the data suggest a lymphoid cell expressing T- and/or B-cell-associated markers and certain activation antigens while lacking immunological features of monocytes-macrophages or other lineages. Molecular genetic studies have demonstrated heterogenous findings with respect to rearrangements of T-cell receptor and immunoglobulin genes. Only a small percentage of the cases has rearrangements; this might be due to the threshold of sensitivity of the method combined with the scarcity of the malignant cells. Epstein-Barr virus (EBV) genomes are clonally integrated in the H-RS cells of about half the cases. The significance of these findings--whether EBV is a causative agent or an epiphenomenon--remains to be elucidated. H-RS cells express mRNA and proteins of various cytokines and cytokine receptors implying a predominant role for cytokines in the pathophysiology of HD. The mononuclear and polynuclear H-RS cells are capable of DNA synthesis and nuclear division; the lack of cellular division leads to multinuclearity through the process of endomitosis. Mutations and expression of only a limited number of oncogenes have been tested thus far. Whether the bcl-2 oncogene is involved in HD remains a matter of debate. Aneuploidy and non-random chromosomal abnormalities are the results of cytogenetic analyses of H-RS cells. However, no chromosomal marker specific for HD has yet been found. Thus, while studies of EBV involvement, growth factor production, oncogene expression and chromosomal abnormalities contributed a fair amount of new data on the nature of H-RS cells, only immunophenotyping and genotyping provided some indication of the cellular derivation: an activated lymphoid cell that possibly expresses oncogenes, that probably is infected with EBV, that most likely produces cytokines, that certainly has multiple karyotypic abnormalities.

Abstract
Serial serum samples from 37 patients with Hodgkin's disease (HD) and 39 healthy controls were studied for antibodies to human herpes virus-6 (HHV-6) using ELISA and indirect immunofluorescent antibody (IFA) tests and to the Epstein-Barr virus (EBV) using a radio-complement fixation assay. Antibodies to HHV-6 in the pre-treatment sera from the HD patients were not significantly different from those of controls, but significant changes in titers related to clinical course were noted among the HD patients. HHV-6 IFA titers increased significantly in the course of follow-up in patients who relapsed and decreased significantly over time in patients who did not. These serologic studies support tissue-based investigations indicating that EBV plays a greater etiologic role in HD than HHV-6, although HHV-6 serology may be of prognostic value or may assist in identifying individuals with immunologic abnormalities. The identification of diverse HHV-6 antibody patterns using different assays may reflect the presence of a number of antibodies with varying implications, similar to those identified for EBV.

Abstract
Paraffin-embedded tissue specimens from 46 cases of Hodgkin's disease (HD) were studied by in situ hybridization with biotinylated probes for the presence of EBV genomes. EBV specific DNA sequences were detected in the nuclei of Reed-Sternberg (RS) and Hodgkin cells (H), in 14 of these 46 cases. There was no correlation between positive hybridization and morphological subtype or site of tumor. By demonstrating an exclusive localization of the viral DNA in the tumor cells of HD, our study adds to the growing body of evidence to suggest an involvement of EBV in the pathogenesis of at least some cases of HD.

Abstract
Epstein-Barr viral (EBV) infections are associated with Hodgkin's disease (HD). To better characterize this relationship, fixed tissues of infectious mononucleosis, normal and reactive lymph nodes, lymph nodes with progressively transformed germinal centers, and biopsy specimens with the different subtypes of HD were analyzed by polymerase chain reaction (PCR). The presence or absence of EBV, the relative amounts of EBV, and the presence of multiple EBV genotypes as defined by amplification of a polymorphic EBV locus were determined for each specimen. Epstein-Barr virus could be detected from all specimens with infectious mononucleosis (eight of eight cases), generally in relatively large amounts, with multiple EBV genotypes evident in two cases. Epstein-Barr virus could not be detected from normal or reactive lymph nodes (none of 39 cases). Small amounts of EBV could be detected from a minority of cases with progressively transformed germinal centers (two of 16 cases), with multiple EBV genotypes evident in one case. Variable amounts of EBV could be detected from approximately half of the specimens with HD (26 of 50 cases). Epstein-Barr virus was most often detected in the subtypes of mixed cellularity (12 of 15 cases), nodular sclerosis (seven of 14 cases), and lymphocyte depletion (five of seven cases) compared with nodular lymphocyte predominance HD (two of 14 cases). In contrast to specimens with infectious mononucleosis and progressively transformed germinal centers, only one EBV genotype was evident in the specimens with HD. These findings are consistent with the hypothesis that some cases of HD may be directly associated with EBV.

Abstract
The Epstein-Barr virus (EBV)-encoded latent gene products, latent membrane protein (LMP) and EBV nuclear antigen 2 (EBNA 2), seem to have important roles in EBV-induced cell transformation in vitro, and have been implicated as important effector molecules in EBV-associated lymphomagenesis. Because up to 35% of Hodgkin's disease (HD) samples have been reported to contain EBV genomes, the expression of LMP and EBNA 2 in these tumours was investigated. 84 cases of HD were studied with monoclonal antibodies and immunohistochemical labelling of acetone-fixed cryostat sections. LMP, but not EBNA 2, was demonstrated in Reed-Sternberg (RS) cells of 40 cases (48%); the two proteins were easily detected in transformed lymphocytes of positive control acute infectious mononucleosis tonsils. LMP expression in RS cells varied according to the histological subtype of HD (1/10 cases [10%] of lymphocyte predominance subtype, 16/50 cases [32%] of nodular sclerosis, 23/24 [96%] cases of mixed cellularity type). That the LMP antibodies showed no substantial cross-reactivity with negative control tissues shows that they are useful probes for the diagnosis of latent EBV infection in tissue sections. The findings suggest that EBV is associated with more cases of HD than was previously recognised, that in positive cases RS cells express a latent infection protein phenotype (LMP+, EBNA 2-) which differs from that of other EBV-associated lymphomas, and that LMP expression is related to histologically aggressive subtypes of HD.

Abstract
Lymph nodes obtained from 7 HIV-positive and 20 HIV-negative patients with Hodgkin's disease were examined for the presence of Epstein-Barr virus antigens and genome. EBV antigens were observed in only 2 out of 20 HIV-negative patients, whereas lymph nodes of HIV-positive patients did not reveal evidence of EBV antigens. By in situ hybridization and Southern blot analysis, EBV genome was found in 5 out of 7 HIV-positive patients; the EBV genome was detected in the nucleus of Reed-Sternberg and Hodgkin's cells. EBV DNA was observed by in situ hybridization and Southern blot analysis in only 3 out of 20 HIV-negative patients with Hodgkin's disease. In both groups, Reed-Sternberg and Hodgkin's cells were negative for C3d EBV receptor. Our results show a statistically significant increased expression of EBV DNA in HIV-positive patients with Hodgkin's disease, as compared with HIV-negative patients with HD.

Abstract
In patients with Hodgkin's disease, titers of IgG antibody against viral capsid antigen of Epstein-Barr virus and the prevalence of antibodies against early antigen are higher than expected. To evaluate whether this condition antedates diagnosis, we identified 43 persons with Hodgkin's disease, from whom blood had been drawn and stored for an average of 50.5 months before diagnosis, and 96 controls from the same populations, from whom blood had been drawn at the same time. The relative risks of Hodgkin's disease associated with elevated levels of IgG and IgA antibodies against capsid antigen were 2.6 (90 percent confidence interval, 1.1 to 6.1) and 3.7 (1.4 to 9.3), respectively. For Epstein-Barr nuclear antigen, the relative risk was 4.0 (1.4 to 11.4), and for early antigen D it was 2.6 (1.1 to 6.1). However, the prevalence of IgM antibody against capsid antigen was substantially lower in patients with Hodgkin's disease (0.22 [0.04 to 1.3]). These associations were stronger in serum samples obtained at least three years before diagnosis than in serum samples obtained closer to diagnosis. We conclude that the development of Hodgkin's disease may in some patients be preceded by enhanced activation of Epstein-Barr virus. Whether Epstein-Barr virus has a direct role in the pathogenesis of the disease or is simply a marker for a more fundamental factor affecting the immune control of latent infections is unknown.

Abstract
A 3-year prospective study of the histologic and clinical features of patients with Hodgkin's disease presenting to the medical units in Harare, Zimbabwe, was undertaken. The histologic pattern of disease was similar to that of other African countries with mixed cellularity and lymphocyte depleted patterns prevailing (58% and 21%, respectively). Unlike most African countries, however, disease occurred most commonly in teenagers and young adults. Nutritional status was poor in just under 50% of the patients. Clinically, the extent of disease at presentation was striking, with over 90% of patients having advanced stage disease in spite of the stated duration of symptoms being moderate. The histologic and clinical findings resembled those reported from other African countries, but in certain aspects the epidemiologic pattern was intermediate between those of affluent and underprivileged communities.

Abstract
Antibody titers to Epstein-Barr virus (EBV)-associated early antigens (EA) and the viral capsid antigen (VCA) were determined by ELISA on 263 sera obtained from healthy donors, patients with Hodgkin's disease (HD), non-Hodgkin lymphomas (NHL), infectious mononucleosis (IM), Burkitt's lymphoma (BL), and nasopharyngeal carcinoma (NPC). As expected, most lymphoma patients showed markedly elevated anti-VCA IgG and anti-EA IgG antibody titers. Only one patient in the NHL group (n = 56) consisting of patients with lymphomas other than chronic lymphocytic leukemia (CLL) and hairy-cell leukemia (HCL), and 3 patients with HCL (n = 19) had high antibody titers of the IgA class to VCA and EA. Seventeen out of 48 patients (36%) with CLL had high IgA anti-VCA titers and 10 of these sera (21%) also contained IgA anti-EA. The geometric mean titer (GMT) of IgA anti-VCA was 2,510, the GMT of IgA anti-EA was 780. These antibody titers were about 10 times lower than the corresponding GMT of the NPC patients investigated in this study. The elevated IgG and IgA antibody titers to VCA and EA in CLL and HCL patients seem to reflect an immunodeficiency secondary to the malignant disease leading to reactivation of latent EBV infection. The possibility that at least some of these B-cell lymphomas are associated with EBV cannot be excluded.

Abstract
A non-Hodgkin's lymphoma was observed in a patient who had been treated for Hodgkin's disease (HD). The initial treatment consisted of radiotherapy alone, but following three subsequent relapses, both chemotherapy and radiotherapy were administered several times. Twenty years later, the biopsy of an isolated cervical lymph node revealed a non-Hodgkin's lymphoma. The histologic subtype was immunoblastic. Cytogenetic studies of the tumoral cells revealed a t(8;14)(q24;q32) translocation. At the same time, multiple chromosomal rearrangements were observed in peripheral blood lymphocytes, especially t(7;14)(q35;q12), which was noted in 6 of 53 mitoses. This anomaly, frequently observed in patients with ataxia telangiectasia or severe immunodeficiency, has not previously been described in such circumstances.

Abstract
The Epstein-Barr virus (EBV) has been consistently found to be associated with Hodgkin's disease (HD) in two ways: cases generally have elevated titer distributions of antibodies against the viral capsid antigen, and the occurrence of HD among persons with a history of EBV infectious mononucleosis is two or three times higher than expected. We evaluated this association by measuring the prevalence and level of antibodies against EBV and related viruses among 304 cases of HD interviewed in a population-based study in comparison to 285 of their siblings. The most significant finding was that antibody titers to the viral capsid antigen of EBV were elevated (greater than or equal to 1:320) in 39% of the cases and in only 14% of the sibling-controls; the relative risk adjusted for age and sex was 4.1. The geometric mean titer was three-fold higher among cases (175.6 vs. 58.1) Subjects who reported a history of IM had a higher distribution of titers than those who did not. Cases also had elevated titers against the early antigen of EBV - the D Component being most prominent. A significantly higher proportion of cases has elevated titers against CMV, relative risk = 3.4, but the prevalence of CMV antibody was relatively low and not consistently higher among cases. The findings support the hypothesis that EBV may play a role in the pathogenesis of HD among persons with elevated titers. The findings neither confirm nor deny a possible role of CMV.
