Chronic hepatitis associated with Epstein-Barr virus infection in an infant
Insights
A prolonged Epstein-Barr virus (EBV) infection caused a chronic illness in an infant, presenting with fever and low blood cell counts. Prednisone treatment improved symptoms, suggesting a link to persistent EBV, not autoimmune disease.
Area of Science:
- Pediatrics
- Virology
- Immunology
Background:
- Chronic illnesses in infants can present with complex symptoms like fever, thrombocytopenia, and hepatosplenomegaly.
- Differentiating between infectious and autoimmune etiologies is crucial for effective treatment.
Observation:
- A 1-year-old infant experienced persistent fever, thrombocytopenia, granulocytopenia, and hepatosplenomegaly.
- Liver biopsy revealed mononuclear cell infiltration and fibrosis.
- Interferon therapy was ineffective, but prednisone improved clinical and biochemical findings.
Findings:
- Extensive immunological and serological tests did not support an autoimmune disease diagnosis.
- Antibody profiling indicated persistent Epstein-Barr virus (EBV) infection as the cause of the prolonged illness.
Implications:
- This case highlights the importance of considering persistent viral infections, such as EBV, in atypical pediatric illnesses.
- The findings suggest that EBV can mimic autoimmune conditions, necessitating specific diagnostic approaches.
- Understanding EBV's role in chronic pediatric diseases can guide future therapeutic strategies.
Abstract:
A 1-year-old infant girl had a chronic illness characterized by persistent intermittent fever, thrombocytopenia, granulocytopenia, and marked hepatosplenomegaly. Histological findings on liver biopsy 307 days after the onset of her illness disclosed marked mononuclear cell infiltration and moderate fibrosis in the portal and perilobular areas. Interferon-therapy induced no clinical and laboratory improvement, whereas the patient's clinical and biochemical findings responded to prednisone. Although these findings suggested a possible autoimmune mechanism, there were no significant findings in extensive immunological and serological tests consistent with autoimmune disease. The profile of antibodies to Epstein-Barr virus (EBV)-specific antigens in the patient demonstrated that this prolonged atypical illness was the result of persistent EBV infection.
