Introduction: Epstein-Barr virus (EBV) infection, with a global prevalence exceeding 95%, typically manifests in children as infectious mononucleosis. However, clinical practice frequently encounters diverse atypical presentations characterized by multisystem involvement, often resulting in an unfavorable clinical course. Our objective is to describe the clinical manifestations and results of EBV infection in a tertiary pediatric hospital in Mexico.
Method: An observational, transversal, retrospective, and descriptive study that included a systematic review of medical records (2012-2022) of patients under 18 years of age with detectable EBV particles in peripheral blood.
Results: The study included 26 patients with a median age of 5 years and a male predominance of 53.8%. Predominant symptoms were fever (85%) and lymphadenopathy (35%). Sixty-five percent had severe and atypical manifestations, including pneumonia and hepatic, hematologic-oncologic, and autoimmune diseases. Anemia, thrombocytopenia and leukopenia were common, with lymphocytosis in 19% of cases. The median EBV viral load was 2816 copies/mL (range: 555-355,500 copies/mL). Four deaths related to EBV infection were reported. Viral load in these cases also varied widely from 594 to 121,000 copies/mL. Supportive care was administered to 85% of patients, while others received antiviral treatment, steroids, and rituximab.
Conclusion: Atypical manifestations were common, especially in children with multisystem involvement. EBV should be considered as a potential contributor to a diverse spectrum of clinical presentations, emphasizing the need for comprehensive evaluation and awareness in clinical diagnosis.
