[The pathogenetic significance of disorders in macrophage function in viral hepatitis B and delta in children]
Insights
Hepatitis B and delta virus infections in children impair macrophage function, with chronic cases showing persistent immune cell dysfunction. BCG vaccine and tactivin may improve macrophage function and aid remission in chronic hepatitis.
Area of Science:
- Immunology
- Hepatology
- Pediatrics
Context:
- Investigates macrophage function in children with acute and chronic Hepatitis B and Hepatitis Delta.
- Assesses chemotaxis, esterase saturation, and nuclear RNA content in mononuclear cells.
- Identifies Hepatitis B virus antigens within these cells.
Purpose:
- To correlate macrophage functional disorders with the severity of acute viral hepatitis.
- To characterize macrophage dysfunction in chronic Hepatitis B and Delta.
- To evaluate the therapeutic potential of BCG vaccine and tactivin in chronic hepatitis.
Summary:
- Macrophage function is significantly impaired in children with acute and chronic Hepatitis B and Delta.
- Chronic Hepatitis B and Delta are associated with stable depression of mononuclear cell function, more pronounced in Hepatitis Delta.
- Hepatitis B virus antigens (HBsAg, HBeAg) are more frequently detected in mononuclear cells of chronically infected children.
Impact:
- Findings suggest a link between macrophage dysfunction and hepatitis severity in pediatric patients.
- Demonstrates the potential of BCG vaccine and tactivin to enhance macrophage function.
- Supports the use of immunomodulatory therapies for inhibiting viral replication and achieving remission in chronic hepatitis B and Delta.
Abstract:
Overall 180 children aged 3 months to 12 years with acute and chronic hepatitis B and delta were examined for macrophagal function. Chemotaxis, saturation with esterase, the content of nuclear RNA were estimated, antigens of HB virus in these cells were identified as well. The data obtained attest to the correlation between the degree of macrophagal function disorders and the gravity of acute virus hepatitis. The chronic disease is characterized by stable depression of mononuclear cells with a tendency toward deeper depression of their function in patients with virus hepatitis delta as well as a higher rate of HBsAg and HBeAg demonstration in these cells. The authors provide evidence for advisability of the use of BCG vaccine and tactivin in patients with the chronic disease, since they improve macrophagal function, promote the inhibition of HB-virus replication and the onset of a stable remission in patients with chronic hepatitis B and delta.
