Objective:
To analyze the correlation between immunoglobulin M (IgM) against viral capsid antigen (VCA) of Epstein-Barr virus (EBV) and T helper 1 and 2 (Th1/Th2) immunocytokines (ICKs) in children with infectious mononucleosis (IM).
Methods:
This is a retrospective study. A total of 40 children with IM treated in our hospital from August 2019 to August 2021 were included in the research group, and another 42 children with upper respiratory tract infection treated during the same period were selected as the control group. The VCA-IgM positive (+) rate and Th1/Th2 ICKs in two groups were detected, and the correlation of VCA-IgM with Th1/Th2 ICKs in IM patients was analyzed.
Results:
The research group was found to have an evidently higher VCA-IgM+ rate than the control group. Moreover, the accuracy of VCA-IgM in detecting IM was as high as 91.46%. In addition, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), interleukin (IL)-6 and IL-10 presented markedly elevated levels in the research group than in the control group, and in VCA-IgM negative (-) patients compared with VCA-IgM+ patients. There was a positive connection between VCA-IgM and Th1/Th2 ICKs.
Conclusions:
IM children showed high VCA-IgM+ rate and imbalance of Th1/Th2 ICKs, and their VCA-IgM and Th1/Th2 ICKs are positively correlated. In addition, VCA-IgM has certain diagnostic value for IM.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
