The second decade of the 21st century has brought us a new coronavirus infection, SARS-CoV-2, which affects not only animals (livestock, companion animals, birds), but also people, causing severe disease in them (COVID-19) with various clinical variants: from upper respiratory tract lesions to sepsis and thromboembolism. Coronaviruses are known to suppress the production of IFN-I. Therefore, administration of IFN-I is a promising strategy for early treatment and prevention of COVID-19. In the Russian Federation, treatment of COVID-19 in children is performed in accordance with the recommendations of the Ministry of Health of Russia and depends on the clinical form of the disease. Mild and moderate forms of the disease, observed in the majority of children, are treated according to the protocols for managing ARVI, bronchitis, bronchiolitis, and pneumonia in children. However, the fact that non-severe COVID-19 shares clinical manifestations with other infections caused by respiratory viruses and herpesviruses (including cytomegalovirus, HHV6A/B, and Epstein-Barr virus), as well as recently increased proportion of mixed viral infections necessitate (until the etiological diagnosis is confirmed) the administration of drugs recommended for the treatment of seasonal ARVI (including intranasal forms of IFN-α, etc.). Such therapeutic tactics often ensures faster improvement and symptom elimination. We report a case of mixed respiratory infection caused by two viruses (SARS-CoV-2 and Epstein–Barr virus) in a child. Early treatment with recombinant interferon-α2b with taurine resulted in fever alleviation and normalization of child’s condition by the moment of transfer to a specialized department. Key words: SARS-CoV-2, COVID-19, children, treatment, interferon.

Recently the role of herpes viruses in an aggravation of inflammatory diseases of the upper respiratory tract, in particular, herpes simplex virus and Epstein − Barr virus, has become increasingly evident in otorhynolaryngology practice. To determine the extent of infection with Epstein − Barr virus and to study the immunogram of the first level for the children with secretory otitis media, 48 patients aged 3−9 years were examined for the purpose of an adequate treatment. Infection was revealed by serological diagnosis (enzyme immunoassay) with the determination of IgM to capsid complex (VCA) and IgG to early antigen (EA). Level 1 immunograms were also determined by immune enzyme analysis. Children with secretive middle otitis (22.9 %) were infected with Epstein − Barr virus, corresponding to an acute phase of the disease, as well as they had a reduce cell immunity. All children received comprehensive treatment for secretory middle otitis. It was concluded about the need for children with middle otitis to be screened for an infection with the Epstein−Barr virus and treated conservatively by an immunologist. Key words: secretory middle otitis media, etiology of Epstein − Barr virus, immune status of children, treatment.

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.

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.

Introduction: Epstein Barr virus (EBV), is a member of the genus Lymphocryptoviridae and Herpesviridae subfamily. It is pervasive and infects more than 90% of the adult population worldwide. In childhood and early adulthood primary infection occurs through salivary contact. The majority of children are asymptomatic, but some adolescents and young adults can develop infectious mononucleosis with harmless clinical manifestations. Objective: To analyze the expression of Epstein Barr Virus (EBV) Latent membrane protein – 1 (LMP-1) in various histological subtypes of gastric carcinoma. Materials and Methods: Out of the 43cases, 32 cases were proven to be malignant, out of which 30 cases who had adequate clinical data were included in the study. The materials were processed and sections were cut at 5 microns. Hematoxylin and eosin staining of sections was done. Histopathological examination of these sections was done. Result: The most common presenting symptom associated with Gastric carcinoma was upper abdominal pain (epigastric pain). Both the LMP-1 IHC positive cases showed a  low score when assessed using the LMP-1 immunohistochemistry scoring system (used in nasopharyngeal carcinomas). This may be due to the older age group of patients. For the effective control of viral cancer, there should be rapid, sensitive, specific, cost-effective diagnostics assays and management. Conclusion: Hence our study justifies the role of EBV in the oncogenesis of gastric carcinoma. More elaborate and extensive studies are warranted to further emphasize this theory.

Abstract Background Familial Mediterranean Fever is a monogenic autoinflammatory disease, secondary to mutation of MEFV gene, and typically expressed with recurrent attacks of fever, serositis, rash, aphthous changes in lips and/or oral mucosa. Kawasaki Disease, an acute systemic vasculitis with persistent fever (5 or more days), rash, stomatitis, conjunctivitis, lymphadenopathy, changes in extremities, is currently considered a multifactorial autoinflammatory disease. An infection, as Epstein Barr virus, can be the trigger of Kawasaki Disease. Case presentation We describe the clinical case of a 3-year-old boy with Kawasaki disease. Successfully treated with intravenous immune globulin, acetyl salicylate acid, he late developed anaemia and thrombocytopenia. The Epstein-Barr virus infection has been demonstrated and he showed a resolution of the clinical manifestations of Kawasaki disease with the persistence of coronaritis, without aneurisms. However, for the personal and familial history of monthly recurrent attacks of fever, pharyngitis, abdominal pain, the genetic study of MEFV was performed and demonstrated 3 heterozygous mutations of MEFV (E148Q, P369S, R408Q). Conclusions Mutations of MEFV can contribute to increase inflammatory expression in other diseases, as Kawasaki disease.

The review is dedicated to features of clinical manifestations of infections caused by Epstein-Barr virus (EBV) in HIV-infected patients, problems of diagnostics and execution of antiviral therapy in the case of combination of these infections. Individuals at AIDS stage develop tumors, associated with EBV: non-Hodgkin’s lymphomas, including Berkitt’s lymphoma, primary B-cell lymphoma ofCNS, nasopharyngeal carcinoma. Formation of lymphoid interstitial pneumonitis and leukoplakia is known to be associated with EBV. A large list of preparations that are inhibitors of EBV replication are currently known, however, there is no clear pathogenetically justified therapy scheme for patients with this infection against the background of HIV-infection.
