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.
