Epstein-Barr Virus (EBV) infection is associated with broad spectrum of clinical manifestationsdepending on the immune status of the host, To analyze their possible role in the complication ofautoimmune hepatitis, we investigated (30) female patients with autoimmune hepatitis type-1 of(10-40)years and 25 healthy female of same ages(control groups). Both groups were carried outto measure the levels of EBV-CA IgM, IgG Ab, EBV-EA IgM, IgG Ab, and EBV-NA IgM, IgGAb using indirect immunoflourescent assay (IFAT).The prevalence of EBV-CA IgM, IgG Ab were(10%,20%) and EBV-EA IgM, IgG Ab were (10% and20%) respectively, while the prevalence ofEBV-NA IgG Ab was( 3.33%) and there are no prevalence of EBV-NA IgM Ab. There weresignificant differences (P≤ 0.05) in percentage of EBV-CA IgG and EBV-EA IgG in patientsgroups compared to control groups, and no significant differences in percentage of EBV-CAIgM and EBV-EA IgM in patients group compared to control group. This indicates thatinfection with Epstien-Barr virus plays a role in the pathogenesis of autoimmune hepatitis type-1.

Background: Given the fact that viral infections play an important role, either directly or indirectly, in around 20 percent of human cancers, this study aimed at investigating the potential association of Epstein–Barr virus (EBV) and cytomegalovirus (CMV) infections in esophageal cancer that is the sixth most common cause of cancer-related deaths. Methods: In this case-control study, a total of 200 paraffin-embedded biopsies of cancerous and benign esophageal tissues were gathered from the biopsy bank of Imam Reza Hospital, Tabriz, Iran in 2017. All samples were first deparaffinized, and then subjected to commercial DNA extraction. The quality of extracted DNA was evaluated by amplification of the beta globulin gene. Identification of EBV and CMV DNA was performed using primers designed for the EBER region of EBV and the immediate early (IE) region of the CMV genome, respectively. Results: The mean age of the subjects in the test and control groups was 52.2 (17.1) and 59.9 (18.9), respectively. The distribution of gender (male/female) in patient and control groups was 54/46 and 53/47, respectively. Our results showed that the frequency of EBV (P < 0.001) and CMV (P < 0.001) in cancerous samples was statistically higher than control group. Moreover, in the cancerous group the rate of EBV was significantly higher in the esophageal adenocarcinomas (EAC) sample (12 out of 70) than esophageal squamous cell carcinomas (ESCC) (0 out of 30) (P = 0.016) but, in the ESCC group, 17 out of 30 subjects were positive for CMV which was significantly higher in comparison with EAC patients (1 out of 70) (P < 0.001). Conclusions: Findings indicated that EBV and CMV might be contributed to the pathogenesis of EAC and ESCC types of esophageal carcinoma, respectively, although further studies are warranted.

BACKGROUND Multiple sclerosis (MS) is a chronic disease with significant morbidity. A wide spectrum of risk factors has been suggested that triggers the development of MS. Among them, several viral infections have been implicated to play a role in MS pathogenesis. We aimed to evaluate the relationship between viral diseases, including Epstein–Barr virus (EBV), human herpes virus 6 (HHV-6), cytomegalovirus (CMV), and hepatitis B virus (HBV) and MS in the present case-control study. METHODS About 100 patients with confirmed MS and age- and sex-matched individuals were selected as case and control groups, respectively. The patients were randomly selected from individuals diagnosed by neurologists based on the clinical signs and symptoms and imaging procedures. RESULTS More than 100 patients with MS and patients who were referred for other causes were analyzed for the presence of DNA of EBV, HHV6, CMV, and HBV separately. 9.37% of the control group had a positive test for the DNA of EBV in a real-time polymerase chain reaction (PCR), while the frequency of positive test result was zero in the case group (p = 0.0012). HBV DNA was not detected in both the case and control groups. The prevalence of CMV was 0.88 and zero in the control and case groups, respectively (p = 0.3410). For HHV6, 9.73 % of the control group had a positive result, while this test was positive in 5.88% of the patients with MS (p = 0.2959). CONCLUSION We detected a significantly higher number of individuals with DNA of EBV in their blood among the control group compared with the case group. In conclusion, the results suggest a surprisingly adverse association between MS and EBV, and no association was found between the presence of DNA of HBV, CMV, and HHV6 and MS.

From 1978 to 1981, 151 patients with nasopharyngeal carcinoma (NPC) were enrolled in a prospective, collaborative study of North American patients, most of them white. Thirty-seven had World Health Organization (WHO) type 1 tumors, and 114 had WHO types 2 and 3 tumors. The anti-Epstein-Barr virus (EBV) profile of elevated antibody titers directed against viral capsid antigen and early antigen was seen in 85% of the patients with WHO types 2 and 3 tumors but in only 16% of the patients with WHO type 1 tumors. Geometric mean titers tended to be higher in higher stages of the disease in several staging systems. Low antibody-dependent cellular cytotoxicity at diagnosis appears to reflect a poorer prognosis, and the determination of antibody titers by this assay may prove to be useful for identifying persons in whom recurrent disease is likely to develop after conventional therapy. Anti-EBV titers can aid in diagnosis and treatment planning in patients with NPC, particularly those with occult primary NPC.

Acute pharyngitis may be caused by a wide variety of microbial agents (Table 1). The relative importance of each of these agents varies greatly depending on a number of epidemiologic factors, including age of the patient, season of the year, and geographic locale. Viruses Most cases of acute pharyngitis are viral in etiology and involve the pharynx as well as other portions of the respiratory tract as manifestations of the common cold, influenza, or croup. Examples include the rhinoviruses, coronaviruses, influenza A and B, and the parainfluenza viruses. Certain viral infections causing sore throat may exhibit clinical manifestations that are rather distinctive. Examples include enteroviruses (herpangina due to Coxsackie A), Epstein-Barr virus (infectious mononucleosis), cytomegalovirus (cytomegalovirus mononucleosis), adenovirus (pharyngoconjunctival fever, acute respiratory disease of military recruits), and herpes simplex virus (pharyngitis, gingivitis, and stomatitis). In many instances, however, the illnesses caused by these agents may overlap so broadly with that of streptococcal pharyngitis as to be clinically indistinguishable. Thus, Epstein-Barr virus, adenovirus, and herpes virus may all cause fever, exudative pharyngitis, and cervical adenitis. Several studies have documented the role of primary herpesvirus type 1 infection as a cause of acute pharyngitis in college students.1-4 Herpesvirus type 2 can occasionally cause a similar illness as a consequence of oral-genital sexual contact.5 Although herpesvirus infections may involve the anterior oral cavity (vesicular or ulcerative gingivostomatitis) as well as the posterior pharynx, they do not routinely do so. Only about one-fourth of students with culturally and serologically proven primary herpes simplex type 1 pharyngitis studied by Glezen et al,2 for example, had gingivostomatitis.

The indices of immune response were studied in 68 patients with infectious mononucleosis caused by the Epstein-Barr virus (35 males, 33 females) aged 18 to 30 years. Materials and methods. The content of soluble forms of differentiation antigens (sCD95, sCD18, sCD50, sHLAI, sCD54) has been studied with enzyme immunoassay using monoclonal antibodies Mab IC0-20 and polyclonal antibodies to the antigens of the mononuclear cells of the peripheral blood. The control group included 60 healthy volunteers matched for age and sex with the main group. The aim of this study is the assessment of the content of soluble forms of differentiation antigens in patients with infectious mononucleosis caused by Epstein-Barr virus, depending on gender, age, severity of illness, comorbidities, laboratory values, the presence of viral DNA, as well as a demonstration of their value in predicting the course and outcome of the disease and the efficacy of antiviral and immunocorrecting therapy. In patients with negative results of DNA indication of EBV a significant increase in the content of soluble forms of differentiation antigens characterizing the adhesion of leukocytes (sCD18), the activity of T-lymphocytes (sCD50), the recognition of foreign antigens (sHLAI) in the blood in comparison with patients with a positive DNA indication of EBV was determined. Conclusion. According to the results of this performed work the criterion for an adequate immune response in patients with infectious mononucleosis caused by the Epstein-Barr virus was found to be the increase of the content of soluble forms of differentiation antigens (sCD95, sCD18, sCD50 sHLAI, sCD54). In patients with exanthema, tonsillar syndrome, leukocytosis, elevation of transaminases and the presence of antibodies to capsid antigen (a/VCAIgM) the content of soluble forms of differentiation antigens (sCD95, sCD18, sCD50 sHLAI, sCD54), was higher than in patients without such symptoms. In the treatment with cycloferon in patients with cyclic course of EBV infectious mononucleosis the content of sHLAI and sCD54 at 2nd-4th weeks of treatment increased by 1.5-2 times compared with the corresponding values before treatment. In patients with reactivation of the disease monotonically low indices of all studied soluble forms of differentiation antigens persisted over the 4 weeks during patients following up. In patients with infectious mononucleosis caused by Epstein-Barr virus, the dynamics of sHLAI and sCD54 after 2-4 weeks of treatment serves as secondary efficacy endpoint of antiviral, immunomodulatory therapy and the formation of the cyclic course of the disease.

AbstractEndemic Burkitt lymphoma (eBL), the most prevalent pediatric cancer in sub-Saharan Africa, is associated with malaria and Epstein Barr virus (EBV). In order to better understand the role of EBV in eBL, we improved viral DNA enrichment methods and generated a total of 98 new EBV genomes from both eBL cases (N=58) and healthy controls (N=40) residing in the same geographic region in Kenya. Comparing cases and controls, we found that EBV type 1 was significantly associated with eBL with 74.5% of patients (41/55) versus 47.5% of healthy children (19/40) carrying type 1 (OR=3.24, 95% CI=1.36 - 7.71,P=0.007). Controlling for EBV type, we also performed a genome-wide association study identifying 6 nonsynonymous variants in the genes EBNA1, EBNA2, BcLF1, and BARF1 that were enriched in eBL patients. Additionally, we observed that viruses isolated from plasma of eBL patients were identical to their tumor counterpart consistent with circulating viral DNA originating from the tumor. We also detected three intertypic recombinants carrying type 1 EBNA2 and type 2 EBNA3 regions as well as one novel genome with a 20 kb deletion resulting in the loss of multiple lytic and virion genes. Comparing EBV types, genes show differential variation rates as type 1 appears to be more divergent. Besides, type 2 demonstrates novel substructures. Overall, our findings address the complexities of EBV population structure and provide new insight into viral variation, which has the potential to influence eBL oncogenesis.Key PointsEBV type 1 is more prevalent in eBL patients compared to the geographically matched healthy control group.Genome-wide association analysis between cases and controls identifies 6 eBL-associated nonsynonymous variants in EBNA1, EBNA2, BcLF1, and BARF1 genes.Analysis of population structure reveals that EBV type 2 exists as two genomic sub groups.
