To study the clinical features of infectious mononucleosis (IM) caused by Epstein-Barr virus (EBV) mixed with Mycoplasma pneumonia (MP) or/and cytomegalovirus (CMV)infection, collected 201 hospitalized children who met the IM diagnostic criteria, the clinical manifestations, laboratory tests, complications, treatment, and outcome were compared among EBV infection alone and EBV mixed with MP or/and CMV infection. Most of the children with IM were preschoolers, more frequently occurred in boys than girls. EBV patients with MP had the longest duration of fever. When mixed pathogen infections were involved, the white blood cell count of preschool children was significantly increased, while splenomegaly was more common in older children. In the cases of EBV infection alone, abnormal liver function was positively correlated with age ( P = 0.044 ). Mixed pathogen infections were more common in children with IM, occurring in all age groups, and some clinical characteristics were related to the age of onset and the pathogen of the infection.

Annotation. Systemic lupus erythematosus (SLE) is a chronic disease characterized by a variety of clinical manifestations with phases of exacerbation and remission, which often complicate the clinician in determining treatment tactics or possible impact on its course of comorbid lesions, including those caused by viral infection. It is known that more than 90.0 % of patients with SLE are infected with cytomegalovirus (CMV) and about 99.5 % with Epstein–Barr virus (EBV). Because CMV and EBV can persist in the human body, more and more attention is being paid to elucidating the effects of active viral infection on the course and activity of SLE, the main pathogenetic mechanism of which is the autoimmune process. The aim of the study was to establish the frequency of cytomegalovirus and Epstein–Barr infections, and their combination in patients with systemic lupus erythematosus depending on the duration of the disease and the degree of its activity. The study involved 120 patients with SLE aged 18 to 69 years, who were in the rheumatology department of the Communal Non-Profit Enterprise of the Lviv Regional Council “Lviv Regional Clinical Hospital” in 2014–2019. To diagnose CMV and EBV infection, antibodies of immunoglobulins M and immunoglobulins G to viruses were detected in blood serum, as well as viruses were detected with polymerase chain reaction and groups of patients were formed: patients with active CMV infection; active EBV; active CMV and EBV; without active CMV and EBV. To achieve the goal, the study was conducted in two stages: determining the frequency of CMV and EBV infection and their combination depending on the duration of SLE (first) and the degree of its activity (second). Statistical analysis was performed in MS Excel using descriptive statistics, Student's t-test to compare samples with normal distribution, χ2-test, z-test to compare two particles; statistically significant relationship was considered when p<0.05. According to our results, active CMV infection is more common in patients with systemic lupus erythematosus duration less than 1 year, active EBV infection – in patients with disease duration greater than 10 years, a combination of active CMV and EBV infection – in patients with systemic lupus erythematosus duration less than 1 year. The increase in the degree of activity of systemic lupus erythematosus is accompanied by a significant (p<0.05) increase in the incidence of active CMV and EBV infection, as well as an increase in mean IgM and IgG antibody titers to these viruses in patients with increasing disease activity.

Introduction. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by various manifestations and clinical course, many aspects of the etiology and pathogenesis of which remain unclear. Recently, the interest of researchers in studying the role of cytomegalovirus (CMV) and Epstein - Barr virus (EBV) has been growing in the occurrence and course of a number of human diseases due to their ability to affect almost all organs and systems of the body, causing the formation of latent, active or chronic infection, which can often cause temporary disability, disability or even death, however, for the patients with SLE, despite the possibility of approaching the difficult problem of diagnosis and treatment of this disease, this issue is given insufficient attention, as evidenced by isolated studies.The aim of the study. Detect cytomegalovirus and Epstein - Barr infection in patients with systemic lupus erythematosus and its dependence on gender and age of patients. Materials and methods of research. The study involved 120 patients (15 men (12.50%) and 105 women (87.50%) aged 18 to 69 years with SLE, who were in the rheumatology department of the Communal Non-Commercial Enterprise of the Lviv Regional Council "Lviv Regional Clinical Hospital" in 2014-2019. To diagnose CMV and EBV infection by enzyme-linked immunosorbent assay, antibodies of IgM and IgG to viruses were detected in blood serum, and viruses were detected by polymerase chain reaction. According to the results of virus detection, formed groups of the patients, namely: patients with active CMV infection, active EBV, active CMV and EBV, without active CMV and EBV. All patients with SLE included in the study were subsequently stratified by age according to the classification of the World Health Organization (2015), according to which the following age limits were determined: young age, middle-aged, elderly, senile. Statistical analysis was performed on a personal computer in MS Excel and Statistica 6.0 using descriptive statistics. The frequency of cases of active CMV and EBV infection was calculated mathematically by the binomial coefficient of I. Newton. Research results and their discussion. We found in the vast majority of patients with SLE (117 patients, 97.50%) increase in the titer of specific antibodies to CMV. Only in 3 patients (2.50%) the titer of antibodies to this virus was within normal limits. Analyzing the frequency of EBV infection in patients with SLE, we recorded an increase in the titer of specific antibodies to the virus in 119 patients (99.17%). Among the examined patients with SLE in all (100.00%) found an increase in the titer of antibodies to CMV and / or EBV, of which 97.50% - infected with CMV and 97.17% - infected with EBV. The active phase of CMV and / or EBV infection was detected in 54.17%, of which 23.33% - active CMV infection, 17.50% - active EBV infection and 12.50% - a combination of active CMV and EBV infection simultaneously, which indicates a high frequency of CMV and EBV infection in patients with SLE and reflects the urgency of the problem of diagnosing herpesvirus infection in them. We found that activeCMV, EBV infections and their combinations are present only in women (64 patients, which is 60.96% of the total number of women with SLE), of which 28 patients (26.67%) there was only active CMV infection, in 21 patients (20.00%) - only active EBV infection and in 15 patients (14.29%) – combination of active CMV and EBV infection. 41 women (39.05%) and all (100.00%) men were not found to have active CMV and EBV infection, which indicates that men at the time of the survey were significantly more likely to have this infection in the integration phase. The most frequently active EBV infection was detected in patients with SLE of young age (17 cases, 24.64%), and in middle-aged patients 3 cases (6.52%) were recorded, which indicates a significant (p <0.05) difference in the frequency of cases of active EBV infection in patients of both groups. Only 1 case (20.00%) of active EBV infection was detected in elderly patients. Conclusions. All patients with systemic lupus erythematosus are infected - 97.50% with cytomegalovirus and 97.17% with Epstein-Barr virus infection, that was confirmed by the increased titer of antibodies to them. Among the mentioned patients 53.33% of them had the active phase of infection (23.33% - cytomegalovirus infection in the replication phase, 17.50% - the Epstein- Barr virus infection in the replication phase and 12.50% - their combination). The prevalence of active viral infection in patients with systemic lupus erythematosus depends on gender (active cytomegalovirus, active Epstein-Barr virus infection and their combination are significantly more common in women) and age - they are probably more common in young patients.

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.

Four atypical cases of presumed infectious mononucleosis (IM) encephalitis are presented. To establish an etiologic diagnosis, Paul-Bunnell-Davidsohn heterophil titers (PBD), antibody titers to the antigens of the Epstein-Barr virus (EBV), and oropharyngeal excretion of EBV were determined. Criteria for a primary EBV infection are (1) an antiviral capsid antigen titer of 1:160 or greater, (2) the presence of antibody to the diffuse component of the early antigen, (3) absence of antibody to the nuclear antigen, and (4) excretion of the virus from the oropharynx. Three of the four cases met these criteria; of the three, one did not have a positive heterophil titer. The fourth case turned out not to be IM; there was a positive PBD heterophil, but there was no evidence of primary EBV infection. Although the PBD heterophil is usually a reliable test to diagnosis IM, it is not always present in children, and it is sometimes nonspecifically elevated. Some EBV titers can be nonspecifically elevated as well; however, the above criteria are diagnostic of primary EBV infection.

Introduction. The presence of etiologically unencrypted diagnoses in the structure of viral hepatitis determines the relevance of searching for other pathogens involved in liver pathology formation. The role of Epstein-Barr virus in the development of hepatitis was described in the scientific literature, but official statistics do not allow to assess its contribution to liver damage along with hepatitis B and C viruses.The purpose – to identify common and distinctive epidemiological features of viral hepatitis B (HB), C (HC) and infectious mononucleosis (IM).Material and methods. A retrospective epidemiological analysis of these nosologies incidence was carried out according to official statistics in 2009-2018 in the Russian Federation.Results and discussion. The multidirectional trends in the long-term dynamics of the incidence of IM, acute and chronic HB and HC and the presence of strong direct correlation between the acute and chronic HB and HC incidence were established. Distinctive features include disparity in epidemic process intensity in different age groups (prevalence of morbidity in children aged 1–2 and 3–6 years with IM and persons older than 18 years – with viral hepatitis). It is common for IM and HB and HC to involve the majority of urban population in the epidemic process, as well as children under the age of 1 year. The described differences are due to the action of transmission mechanisms specific to each infection.Conclusion. The results obtained in this study may serve as a basis for further study of the interaction of EpsteinBarr virus with hepatitis B and C viruses.

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.

Epstein-Barr virus (EBV), the accepted cause of infectious mononucleosis (IM), has been associated with a variety of neurologic disorders including encephalitis, aseptic meningitis, transverse myelitis, Guillain-Barré syndrome, and Bell's Palsy.1,2 These neurologic syndromes may occur as the sole manifestation of EBV infection or together with the more typical clinical features of IM. It is unclear whether the central nervous manifestations of EBV result from direct invasion of the central nervous system by EBV or from a more indirect mechanism. This report describes the recovery of EBV from the spinal fluid of an 11-year-old boy with IM and encephalitis. CASE REPORT

We agree with the opinion of Tamir et al.1 that the Paul-Bunnell and mononucleosis tests are of little value in children. In Japan, infectious mononucleosis is not common. Illness caused by Epstein-Barr virus (EBV) infection is rare after infancy because the positive antibody sera to EBV is 30% to 40% in the sera of infants between 1 and 24 months old. This increases rapidly to about 80% by 3 years of age.2 Primary EBV infection may occur before the age of 3 years.

Objective: The aim of the study was to analyze the clinical characteristics of pediatric patients with ocular toxocariasis. Methods: Ocular toxocariasis was diagnosed and treated in 46 children from Shanghai and surrounding provinces. The diagnosis of ocular toxocariasis was confirmed immunologically by performing an enzyme-linked immunosorbent assay on serum and/or intraocular fluid. All pediatric patients and their guardians completed a questionnaire concerning their cases and living habits. Results: The mean age of onset was 6 ± 3 years. Most children (85%) resided in rural areas, and 91% of the children had contact with adult dogs or puppies. At the first visit, visual acuity (VA) was <20/200 in 36 cases, and we detected peripheral granuloma in 36 patients. In our study, the most common signs were vitritis, vitreous strands, and tractional retinal detachment. The Optomap 200Tx device detected granuloma with an 85% sensitivity, which is much higher than that of other techniques. We treated 40 cases (87%) with topical corticosteroids, while 28 patients (61%) were treated with systemic corticosteroids. Only 18 children (39%) required surgical intervention. All patients were examined and treated by the same ophthalmologists. Conclusions: Preschool children in China are more often affected by toxocariasis compared with other age groups. The most common signs included unilateral granuloma and ocular inflammation. In our study, clinical manifestations were severe and complicated. At the first visit, VA was <20/200 in most patients. Ocular toxocariasis was diagnosed on the basis of clinical signs and symptoms; the diagnosis was confirmed by immunological testing. Techniques using the Optomap 200Tx device can facilitate the early detection and lead to better visual prognosis.
