RESUMO
Non-hepatotropic viruses such as Epstein-Barr virus(EBV) has high infection rate in the population with biological characteristics of infective-latent-activation. EBV-related diseases including infectious mononucleosis(IM), chronic active EBV infection(CAEBV), EBV-related tumors and other diseases are complex and diverse, and all these can lead to varying degrees of liver damage.CAEBV can induce hepatitis(chronic active Epstein-Barr virus hepatitis, CAEBVH) or even liver failure. The prognosis of the disease is poor and the mortality rate is high. Early identification, diagnosis, and multidisciplinary collaborative treatment of CAEBVH are key to improving the prognosis of patients. This article will review the diagnosis and treatment progress of CAEBVH, and provide references for clinicians to diagnose and treat CAEBVH.
RESUMO
Chronic active EBV (CAEBV) infection presents with persistent or recurring IM-like symptoms including fever, hepatosplenomegaly, lymphadenopathy, and liver dysfunction without definite underlying diseases at the diagnosis. No causative pathogenetic mechanisms have been sufficiently clarified, these patients have high EBV-DNA load in the peripheral blood and systemic clonal expansion of EBV-infected T cells, NK cells and B cells. Their prognosis is poor with life-threatening complications including hemophagocytic lymphohistiocytosis, diverse organ failure, malignant lymphomas and so on. Allogeneic hematopoietic stem cell transplantation(Allo-HSCT)is the only effective therapy at present. This review outlines the recent progress of CAEBV clinical and fundamental research at home and abroad.
RESUMO
Infectious mononucleosis caused by primary infection of Epstein-Barr virus (EBV) is a self-limiting lymphoproliferative disease, and shows concomitant clinical features such as pyrexia, anorexia, sore throat, cervical lymphadenopathy, liver dysfunction and hepatosplenomegaly. In rare cases, EBV establishes a latent infection in B lymphocytes and runs a chronic course and shows infectious mononucleosis-like symptoms repeatedly. This syndrome, named chronic active EBV infection, may trigger an autoimmune disease that mainly affectes the liver and red blood cells, and carries a very poor prognosis. The cardiovascular complications of chronic active EBV infection are very rare and may be associated with coronary arterial disease. This case describes a 5-year-old boy, who developed chronic active EBV infection and was diagnosed as having autoimmune hepatitis with a coronary aneurysm.
