Serious consequences of Epstein-Barr virus infection: Hemophagocytic lymphohistocytosis

Abstract

Human is the host of the Epstein-Barr virus (EBV) especially in childhood and adolescence. Most of them are asymptomatic infection and self-limiting. However, for those patients who suffer from immune dysfunction, EBV infection will be life-threatening. Epstein-Barr virus-associated hemophagocytic lymphohistocytosis (EBV-HLH) is one of the severe effects. The diagnosis and differential diagnosis of EBV-HLH and other EBV infectious diseases are mentioned in this paper. The molecular biology mechanism and complications of EBV-HLH are equally briefly presented. It also provides a practical method for the genetic diagnosis of such diseases and the differential diagnosis with other human immunodeficiency diseases for medical scientists in routine clinical practice.
