Insights
This study on Epstein-Barr virus (EBV)-associated infectious mononucleosis (IM) in children found that clinical assessment is key for management. Laboratory findings support clinical evaluation but are not primary predictors of outcomes.
Area of Science:
- Pediatrics
- Infectious Diseases
- Virology
Background:
- Epstein-Barr virus (EBV) causes infectious mononucleosis (IM), a common illness in adolescents and young adults.
- Understanding the clinical and laboratory features of EBV-IM in hospitalized pediatric patients is crucial for effective management.
Purpose of the Study:
- To analyze the demographic, laboratory, and clinical characteristics of pediatric patients hospitalized with EBV-associated IM.
- To identify predictors of complications and hospitalization duration in this patient cohort.
Main Methods:
- Retrospective analysis of 212 patients under 18 years old hospitalized with EBV-IM over a 6-year period.
- Data collected included demographics, symptoms, laboratory values, complications, and hospitalization duration.
- Multiple linear regression analysis was used to identify predictors of hospitalization duration.
Main Results:
- The median age was 14.7 years, with most patients aged 13-18 years.
- Common symptoms included fever, tonsillitis, lymphadenopathy, hepatomegaly, and splenomegaly.
- Tonsillar hypertrophy and thrombocytopenia were common complications; however, all patients had favorable outcomes. Patients with three or more complications or thrombocytopenia had longer hospital stays.
- Platelet count, bilirubin, ESR, and AST were accurate predictors of hospitalization duration.
Conclusions:
- Clinical assessment is the most reliable parameter for managing pediatric EBV-IM.
- Laboratory findings play a supportive role in patient management.
- While complications can prolong hospitalization, outcomes for pediatric EBV-IM are generally favorable.
Abstract:
The aim of this retrospective 6-year study was to analyze demographic, laboratory and clinical features of 212 patients (<18 years of age) with EBV-associated infectious mononucleosis (IM) hospitalized in a tertiary clinical care center in southeastern Europe and to identify possible predictors of complications. The median patient age was 14.7 years (IQR 7.7-16.5 years), with 59.4% of patients aged between 13 and 18 years. A total of 51.2% of patients were hospitalized within 7 days following the onset of symptoms (median duration of hospitalization was 9 days, IQR 7-11 days). The most common symptoms included fever (97.16%), tonsillitis (87.3%), lymphadenopathy (79.2%), hepatomegaly (77.4%) and splenomegaly (73.1%). Symptom distribution, maximal fever and fever duration did not differ among different age groups. The most common complications included tonsillar hypertrophy, thrombocytopenia, anemia, neutropenia and leukopenia but all patients showed favorable outcomes. Patients who developed three or more complications and those presenting with thrombocytopenia showed significantly longer hospitalization durations. Platelet count, bilirubin, ESR and AST were identified as the most accurate predictors of hospitalization duration using multiple linear regression analysis. Therefore, our results suggest that clinical assessment of individual patients remains the most reliable parameter for patient management and that laboratory findings play only a supporting role.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
