A retrospective analysis was performed for the clinical data of four children with Epstein-Barr virus (EBV)-related acute liver failure. There were two boys and two girls with a median age of 10 months (range 8.5-44 months). Of the four children, three were diagnosed with infectious mononucleosis (IM), among whom two met the diagnostic criteria of hemophagocytic lymphohistiocytosis (HLH), and one was diagnosed with past EBV infection. All the children had positive EBV DNA in blood and all had pyrexia, hepatomegaly, and jaundice on admission. Three children had the symptom of splenomegaly, ascites, or vomiting. Two children had enlargement of cervical lymph nodes, skin rash, or pleural effusion. One child had gastrointestinal bleeding or stage 2 hepatic encephalopathy. All the children had an abnormal lymphocyte count of <10%, and only one child had leukocytosis and thrombocytopenia. Among the four children, alanine aminotransferase level increased by 10-100 times; total bilirubin level increased by 3-5 times; lactate dehydrogenase level increased by many 10 times; prothrombin time prolonged significantly. All the children were given antiviral therapy with intravenously injected acyclovir or ganciclovir, as well as hepatocyte growth factor to promote hepatocyte growth and hormone to alleviate inflammatory response. Two children were given plasma exchange in addition, among whom one was given the combination of continuous venovenous hemodiafiltration. Two children with HLH were given chemotherapy according to the HLH-2004 regimen. Three children survived, and one child with HLH died of multiple organ failure. It is concluded that EBV infection can cause acute liver failure and that early use of multimodality therapy including blood purification may be beneficial for prognosis in these children.

Aim - to study the effect of different pathogens (EBV, CMV, HHV-6, and MIXT) on the severity of clinical-paraclinical manifestations of infectious mononucleosis in children. The clinical and laboratory study performed for 410 children aged from 10 months up to 12 years with infectious mononucleosis. The association of herpes viruses, mainly EBV, CMV and HHV type 6, takes part in the formation of the clinical picture of IM in (52,9%) of cases. The sole participation of EBV in the development of IM was observed only in (34,1%), CMV (9,02%) and HHV-6 in (3,17%) patients. The etiology of infectious mononucleosis in children affects the acuity, severity, and intensity of the clinical and paraclinical signs of the disease. Infectious mononucleosis VEB etiology is manifested by acute onset (79,5%), intoxication (70,5%), subfebrile and febrile fever up to 7 days (61,03%), lacunar tonsillitis (85,8%), hepatomegaly ( 88,2%), splenomegaly (63,8%), mostly moderate (81,7%) with lymphocytosis (62,9%) and monocytosis (20,5%). For CMV mononucleosis - acute onset (89,9%), severe course (29,8%), febrile and high fever for up to 7 (56,7%) or more days, neutrophilic leukocytosis (73,55) with atypical mononuclear cells (64,7%) and anemia (29,7%). Severe (33,3%), with prolonged high fever (50%), exanthema syndrome (33,3%), pharyngitis without tonsillitis (66,7%), leukocytosis (66,7%) with accelerated ESR (66,7%) and monocytosis (33,3%) are characteristic of HHV-6 infection. For MIXT - acute onset (78,3%), intoxication (79,7%), lacunar tonsillitis (92,9%), hepatomegaly (84,1%) and splenomegaly (67%), low-grade and febrile fever from 3- x (27,1%) up to 7 days (35,05%), lymphocytosis (55,3%) with neutropenia (57,4%), atypical mononuclear cells (48,2%) and hypochromic anemia (17,29 %).

Epstein-Barr virus (EBV) infection occurs commonly in children and presents as a primary or reactivated infection, which are difficult for clinicians to distinguish. This study investigated the clinical characteristics of the two types of infections. Children with detectable plasma EBV-DNA were retrospectively enrolled and divided into primary and reactivated infection group by EBV-specific antibody. We analyzed the patients' characteristics, clinical manifestations, complications, inflammatory biomarkers, and viral load. A total of 9.3% of children with reactivation were immunocompromised over the long-term. The primary infection mostly appeared as infectious mononucleosis (99.8%), while reactivation occurred as an infectious mononucleosis-like disease (65.0%), hemophagocytic syndrome (22.6%), chronic active EBV infection (5.3%) and lymphoma (3.5%). The incidence of fevers, cervical lymphoditis, periorbital edema, pharyngotonsillitis, hepatomegaly and splenomegaly in primary infection were 93.3%, 93.0%, 51.5%, 66.0%, 76.2% and 63.9%, respectively; the incidence of those symptoms in reactivation was 84.0%, 46.9%, 15.4%, 18.5%, 18.5%, and 43.3%, respectively. The incidence of digestive, respiratory, cardiovascular, neurological, hematological, genitourinary complications and multiple serous effusion in primary infection was 68.8%, 18.1%, 8.0%, 0.8%, 2.9%, 0.0% and 2.3%; whereas the incidence of these complications in reactivation was 56.2%, 22.5%, 14.1%, 8.0%, 38.9%, 0.3% and 19.0%. Patients with reactivation were more prone to multi-systemic damage. B-cells were lower, and CD8+ T-cells were higher in primary infection. Viral load was correlated with the level of different cytokines in primary and reactivated infection. EBV primary infection often presents as infectious mononucleosis. The reactivated infection affects more immunocompromised subjects with diverse and complex manifestations. Various complications are more commonly associated with reactivation as a result of different inflammatory responses to different types of infection.
