Abstract
INTRODUCTION Severe acute hepatitis (SAH) is defined by a severe inflammation of hepatocytes in the liver parenchyma which can lead to an acute liver failure, a clinical condition with high mortality rate that can be triggered by several factors but is usually associated to hepatotropic viruses' infection. In 2022, cases of children with severe acute hepatitis of unknown origin hospitalized in Glasgow, Scotland, were reported. Possible causes of this condition include, but are not limited to, undiagnosed viral (and non-viral) infections, autoimmune hepatitis, drug and/or chemical toxicity, mitochondrial chain respiratory and metabolic disorders. AREAS COVERED Herpesviruses can cause severe acute hepatitis, but little is known about the role and the mechanisms of herpesviruses as a causative agent of this type of hepatitis. We review the role of herpesviruses as causative agent of SAH in children and other possible mechanisms involved in this disease. EXPERT OPINION Differential diagnosis for herpesvirus in SAH should be implemented in all settings. Alternative fluids, such as saliva and dried blood, could be used in the diagnosis to overwhelm the availability of biological specimens at sufficient volume. In the future, genetic studies could also be added to increase the knowledge about severe acute hepatitis in children.

Abstract
Epstein-Barr virus (EBV) is an oncogenic virus classified by the World Health Organization as a class 1 carcinogen. Post-transplant lymphoproliferative disorders are believed to be strongly related to an EBV infection. Monitoring of EBV DNAemia is recommended to assess the risk of reactivation of latent infection and to assess the effectiveness of therapy. Currently, various types of clinical specimens are used for this purpose. The aim of the study was to assess a reliable method of EBV viral load investigation depending on the clinical material used: whole blood or plasma samples. We found that of 134 EBV-DNA-positive whole-blood samples derived from 51 patients (mostly hemato-oncology or post-transplantation), only 43 (32.1%) were plasma-positive. Of these, 37 (86.0%) had lower plasma DNAemia compared to the corresponding whole-blood samples. We conclude that whole-blood samples have a higher sensitivity than plasma samples in EBV DNA detection. The clinical utility of the tests is unclear, but our results suggest that either whole blood or plasma should be used consistently for EBV viral load monitoring.

Abstract
Objective To investigate the epidemiology and infectious characteristics of Epstein-Barr virus (EBV) infection among children in Shanghai, China from 2017 to 2022. Methods We conducted a retrospective analysis of 10,260 inpatient patients who were subjected EBV nucleic acid testing from July 2017 to December 2022. Demographic information, clinical diagnosis, laboratory findings, etc. were collected and analyzed. EBV nucleic acid testing were performed by real-time PCR. Results A total of 2192 (21.4%) inpatient children were EBV-positive, with the average age of 7.3 ± 0.1 y. EBV detection was stable from 2017 to 2020 (26.9~30.1%), but showed essential decreases in 2021 (16.0%) and 2022 (9.0%). EBV was highest (>30%) detected from three quarters (Q) including 2018-Q4, 2019-Q4 and 2020-Q3. There were 24.5% of EBV coinfection with other pathogens, including bacteria (16.8%), other viruses (7.1%) and fungi (0.7%). EBV viral loads increased when coinfecting with bacteria ((142.2 ± 40.1) ×104/mL) or other viruses ((165.7 ± 37.4) ×104/mL). CRP significantly increased in EBV/fungi coinfection, while procalcitonin (PCT) and IL-6 showed remarkable increases in EBV/bacteria coinfection. Most (58.9%) of EBV-associated diseases belonged to immune disorders. The primary EBV-related diseases were systemic lupus erythematosus (SLE, 16.1%), immunodeficiency (12.4%), infectious mononucleosis (IM, 10.7%), pneumonia (10.4%) and Henoch-schonlein purpura (HSP, 10.2%). EBV viral loads were highest ((233.7 ± 27.4) × 104/mL) in patients with IM. Conclusion EBV was prevalent among children in China, the viral loads increased when coinfecting with bacteria or other viruses. SLE, immunodeficiency and IM were the primary EBV-related diseases.

Epidemiological characteristics and disease burden of infectious mononucleosis in hospitalized children in the mainland of China: a nationwide retrospective study. Virol Sin 2022; 37:637-645.

Abstract
Epstein-Barr virus (EBV) is very common, with the infection rate in adults over 90% worldwide. Infectious mononucleosis (IM) is caused by primary infection with EBV. Most IM patients are generally considered to have a favorable prognosis, but a few patients will also develop complications. Children with severe symptoms will require hospitalization. However, the disease burden of children hospitalized with IM in China has been rarely described. In this study, we included the Face sheets of discharge medical records from 27 member children's hospitals of Futang Research Center of Pediatric Development from Jan 1st, 2016 to Dec 31st, 2020, and medical information such as gender, age, region, time of admission, length of stay and expenditure were extracted. There are 24,120 IM cases, which accounted for 0.42% (24,120/5,693,262) of all hospitalized cases during this period. The ratio of male to female was 1.48:1. Hospitalization for IM in the 4-6 y age group was the highest among inpatients of all age groups. Case numbers increased year by year between 2016 to 2020, and the monthly hospitalization was generally high from Jul to Sep but reduced from Jan to Feb per year. Bronchitis/pneumonia and hepatic dysfunction are two common complications in hospitalized IM patients. The median length of stay was 8 days, and the median cost of hospitalization was 970.59 US dollars. This study will help understand the epidemiological characteristics and disease burden of hospitalized children with IM in China.

Abstract
Multiple sclerosis is a neurodegenerative and autoimmune disease of the central nervous system that mainly affects young people, especially women; its origin has been associated with infection caused by the Epstein-Barr virus. However, not all people who have suffered infection by this virus develop multiple sclerosis, so it would be important to know the role of genetic variability, especially the individual allelic variability of the human leukocyte antigen; as well as to determine the molecular mechanisms and the immunological links of the virus when it remains latent inside the B lymphocytes. Based on the above, it could be defined if the virus is a necessary condition to develop the disease or if there are other factors that need to be present, and thus be able to establish specific prevention and treatment strategies. But the most relevant thing is that the virus is a present condition to develop multiple sclerosis and is potentially preventable through the design of the respective vaccine.

Investigation on the Correlation between Serum Immune Factor Levels and Allergic Constitution in Children with Infectious Mononucleosis.

Abstract
Objective To investigate the correlation between serum immune factor levels and allergic constitution in children with infectious mononucleosis. Methods A total of 120 children who visited our hospital from March, 2019, to December, 2020, were selected as the research objects, and 40 children who came to our hospital for physical examination were included in the control group (CG). 40 children with IM were classified into the IM group (IG), and 40 IM children with allergic rhinitis, allergic dermatitis, asthma, and other allergic diseases were classified into the IM allergy group (AG). On the second day of admission, 5 ml of fasting venous blood was collected from all children in the early morning to observe the serum IgE level, the level of lymphocyte subsets, and the level of immunoglobulin of the patient. Results The serum CD3, CD4, and CD8 levels of children in AG were significantly higher than those in IG and CG (P < 0.05). The serum IgE, IgA, IgM, and IgG levels of children in AG were significantly higher than those of IG and CG (P < 0.05). The serum IgE levels of children in AG were positively correlated with the serum CD3, CD4, and CD8 levels (P < 0.05). There was a positive correlation between the serum IgE level and serum IgA, IgM, and IgG levels in children with AG (P < 0.05). Conclusion The results of this study showed that there may be a certain relationship between allergic constitution and the incidence, clinical manifestations, and prognosis of infectious mononucleosis. IgE level can be used as a reference index for the early severity of IM clinical symptoms.
