Insights
Infectious mononucleosis presents differently in children based on age. Younger children experience more nasal symptoms, while older children show higher liver enzymes and atypical lymphocytes, impacting clinical decisions.
Area of Science:
- Pediatric Infectious Diseases
- Clinical Immunology
Background:
- Infectious mononucleosis (IM), a common viral illness, presents with varied symptoms.
- Understanding age-specific clinical manifestations is crucial for accurate diagnosis and management in pediatric populations.
Purpose of the Study:
- To investigate and delineate the clinical manifestations of infectious mononucleosis in children across different age groups.
- To identify age-related differences in symptoms and laboratory findings associated with IM in pediatric patients.
Main Methods:
- Retrospective analysis of clinical data from 61 pediatric patients diagnosed with infectious mononucleosis between May 2015 and April 2019.
- Patients were categorized into three age strata: 1-3 years, 4-6 years, and 7-14 years for comparative analysis.
Main Results:
- Common symptoms included fever (98.3%), tonsillitis (100%), cervical lymphadenopathy (98.3%), tonsillar exudate (83.6%), hepatomegaly (37.7%), and splenomegaly (42.6%).
- Younger children (1-6 years) exhibited more pronounced nasal obstruction, whereas older children (7-14 years) presented with elevated alanine aminotransferase and increased atypical lymphocytes.
- Disease onset peaked in early childhood and preschool ages (37.7% each).
Conclusions:
- Clinical manifestations of infectious mononucleosis in children vary significantly with age.
- Recognizing these age-dependent differences is essential for effective clinical decision-making and patient care.
Objective:
To investigate the clinical manifestations of infectious mononucleosis in children of different ages.
Methods:
Clinical data from pediatric patients with infectious mononucleosis admitted from May 2015 to April 2019 were retrospectively analyzed. Patients were stratified into three groups (age 1-3 years, 4-6 years, and 7-14 years) for analysis of clinical and laboratory results.
Results:
Data from 61 patients (male:female ratio 1.18:1) aged 5.15 ± 2.93 years (mean ± standard deviation; range: 1-14 years) were analyzed. Infectious mononucleosis occurred throughout the year and the main clinical manifestations were fever (98.3%), tonsillitis (100%), tonsillar white exudate (83.6%), cervical lymphadenopathy (98.3%), hepatomegaly (37.7%), splenomegaly (42.6%), eyelid edema (41.0%), and nasal obstruction (49.2%). Disease onset was most common during early childhood (37.7%) and at preschool age (37.7%). Younger children had more obvious symptoms of nasal obstruction and older children had more significant elevations of alanine aminotransferase and higher percentages of atypical lymphocytes.
Conclusion:
The clinical manifestations of infectious mononucleosis in children differed by age. These associations required attention for clinical decision making.

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...
