[Indicators of immunologic reactivity in children with chronic laryngostenosis]
Insights
Immunological factors are key in pediatric laryngeal papillomatosis and stenosis. Treatment impacts circulating immune complexes, lysozyme, and complement activity, aiding therapeutic monitoring.
Area of Science:
- Immunology
- Otolaryngology
- Pediatrics
Context:
- Pediatric laryngeal papillomatosis and chronic cicatricial stenosis present complex etiological challenges.
- Immunological dysregulation is increasingly implicated in these laryngeal conditions.
Purpose:
- To investigate the role of specific immunological markers in the pathogenesis of pediatric laryngeal papillomatosis and cicatricial stenosis.
- To monitor changes in these markers during treatment and assess their correlation with therapeutic outcomes.
Summary:
- This study examined 40 children with laryngeal papillomatosis or cicatricial stenosis, measuring circulating immune complexes (CIC), salivary and serum lysozyme, and serum complement activity.
- Elevated CIC, lysozyme, and complement activity were observed, suggesting an immunopathological basis.
- Treatment led to increased salivary lysozyme in all patients. Papillomatosis patients showed decreased CIC, while stenosis patients exhibited reduced complement activity, indicating disease-specific responses.
Impact:
- Findings highlight the significant role of immunobiological factors in the pathogenesis of these pediatric laryngeal diseases.
- The study suggests that monitoring CIC, lysozyme, and complement activity can aid in evaluating therapeutic efficacy and predicting disease prognosis.
- Results support the consideration of an autoimmune component in the pathogenesis, potentially guiding future treatment strategies.
Abstract:
Immunological examinations of 40 children with papillomatosis and chronic cicatricial stenosis of the larynx included measurements of circulating immune complexes (CIC) and lysozyme in the saliva and serum as well as complement activity in serum. The examinations were performed regularly during treatment. It was found that immunobiological factors played an important part in the pathogenesis of papillomatosis and cicatricial stenosis of the larynx in children. It was shown that CIC and lysozyme concentrations in the saliva and serum as well as complement activity in serum increased. In the course of treatment all the groups displayed an increase of lysozyme in the saliva; patients with papillomatosis showed a decrease of the CIC concentration and those with cicatricial stenosis a decline of complement activity in serum. Involvement of the autoimmune component in the pathogenesis of the above diseases is discussed. Applicability of the results for controlling the therapeutic efficacy and predicting the outcome of diseases is considered.
