OBJECTIVES: Our objective was to investigate the clinical characteristics, complications, and treatment outcomes of Epstein-Barr virus (EBV)-related infectious mononucleosis (IM) in children and to identify risk factors associated with prolonged fever and abnormal liver function.
METHODS: This retrospective study included 3006 children admitted to Shenzhen Children's Hospital from May 2009 to April 2024 with suspected EBV-related IM. After excluding cases without etiological evidence and those with underlying diseases, 2660 cases were analyzed. Data on demographics, clinical manifestations, laboratory findings, complications, and treatment outcomes were collected. Logistic regression was used to identify risk factors for prolonged fever and abnormal liver function.
RESULTS: Among the 2660 confirmed cases, patients ranged from 8 months to 17 years of age, with a median age of 4 years and a male-to-female ratio of 1.46:1. Co-infections were identified in 369 (13.9%) patients, predominantly with Group A Streptococcus. Complications occurred in 560 (24.46%) of the 2289 patients without co-infections, with bronchitis being the most common (42.68%). Elevated ferritin and atypical lymphocyte percentage were associated with prolonged fever (p < 0.001), while elevated lactate dehydrogenase (LDH) and a lower CD4% predicted abnormal liver function (p < 0.001). Antiviral therapy did not shorten fever duration or hospital stay but prolonged both when combined with corticosteroids or intravenous immunoglobulin (IVIG) (p < 0.001).
CONCLUSIONS: Specific laboratory markers such as ferritin, atypical lymphocyte percentage, LDH, and CD4% are important predictors of prolonged fever or liver dysfunction in EBV-IM. Our findings suggest that antiviral therapy may not be beneficial in uncomplicated cases and highlight the need for tailored treatment strategies to optimize patient outcomes.
