[Infectious hepatitis. I. Presence of HBs antigen]
Insights
Hepatitis B surface antigen (HBsAg) positivity in children with icteric hepatitis indicates a prolonged disease course. Persistent HBsAg correlates with longer-lasting hepatitis, impacting pediatric patient outcomes.
Area of Science:
- Pediatric Hepatology
- Virology
- Immunology
Context:
- Icteric hepatitis in children presents diverse clinical trajectories.
- Longitudinal studies are crucial for understanding disease progression in pediatric hepatitis.
Purpose:
- To investigate the correlation between Hepatitis B surface antigen (HBsAg) presence and the clinical evolution of icteric hepatitis in pediatric patients.
- To analyze the duration and significance of HBsAg positivity in children with hepatitis.
Summary:
- A prospective study followed 268 pediatric patients with icteric hepatitis for at least one year.
- HBsAg was detected in 34 patients; 20 of 28 with acute, long evolution showed transient positivity (avg. 46 days).
- The remaining 8 patients had HBsAg positivity lasting 6 months to 2 years, indicating a risk factor for prolonged disease.
Impact:
- Identifies HBsAg as a potential indicator for prolonged icteric hepatitis in children.
- Provides data on HBsAg persistence duration, aiding in prognosis and management strategies.
- Highlights the importance of monitoring HBsAg in pediatric hepatitis for predicting disease course.
Abstract:
A prospective study in 268 patients of different pediatric ages affected with icteric hepatitis is presented, with a longitudinal follow-up of one year minimum. Different types of clinical evolution are described and related to the presence of HBs antigen. In 34 of the 268 patients HBs antigen was positive; in 20 of 28 patients with acute and long evolution, positivity of the antigen was transitory with an average of 46 days; in the remaining 8 of 28 patients it extended from 6 months to less than 2 years. The presence of HBs antigen is a risk that may be correlated with the tendency to extend the prolonged.
