Abstract:
Objective:To investigate the relationship between the peak load of Epstein-Barr virus (EPV) and live function damage in children with infectious mononucleosis caused by EPV.Methods:Eighty children with infectious mononucleosis caused by EPV who received treatment in Pingxiang People's Hospital from January 2018 to December 2021 were included in this study. Five mL of venous blood was taken from each child for detecting the peak load of EBV-DNA and liver function indicators. These children were divided into a low-load group ( n = 25, EBV-DNA load < 10 4 copies/mL), a medium-load group ( n = 34, EBV-DNA load of 10 4-10 5 copies/mL), and a high-load group ( n = 21, EBV-DNA load > 10 5 copies/mL) according to the peak EBV-DNA load. The relationships between different peak loads of EBV-DNA and live function, age, and sex were analyzed. Results:The rate of liver dysfunction in the high-load group [85.71% (18/21)] was significantly higher than [38.24% (13/34)] in the medium-load group and [20.00% (5/25)] in the low-load group ( χ2 = 11.90, 19.71, P = 0.001, P < 0.001). Alanine aminotransferase and aspartate aminotransferase levels in the high-load group were (156.24 ± 13.21) U/L and (171.69 ± 13.49) U/L, respectively, which were significantly higher than (125.89 ± 10.54) U/L and (143.26 ± 10.29) U/L in the medium-load group and (89.64 ± 6.75) U/L and (64.89 ± 5.74) U/L] in the low-load group (all P < 0.001). There was no significant difference in the peak load of EBV-DNA between children of different ages and between children of different sexes (both P > 0.05). Conclusion:Children with infectious mononucleosis caused by EPV have a high EBV-DNA peak load. A higher peak load of EVB-DNA indicates a higher risk of liver function damage. More attention should be paid in clinical practice. Effective diagnosis and treatment should be performed in time to control the patient's condition as early as possible.
