Insights
This study found significant caspase-3 protein expression in inflammatory adenoid tissue in children. However, this expression did not correlate with nasal steroid treatment effectiveness for adenoid hypertrophy.
Area of Science:
- Pediatric Otolaryngology
- Molecular Biology
- Cellular Pathology
Background:
- Adenoid hypertrophy is a common pediatric condition requiring intervention.
- Intranasal steroids are a potential conservative treatment, aiming to reduce adenoid size via apoptosis.
- Caspase-3 is a key protein in initiating apoptosis.
Purpose of the Study:
- To investigate caspase-3 protein expression in pediatric adenoid tissues.
- To compare caspase-3 expression in inflammatory versus epithelial adenoid tissue.
- To determine if caspase-3 expression correlates with intranasal steroid administration.
Main Methods:
- Immunohistochemical staining for caspase-3 was performed on 51 pediatric adenoid tissue samples.
- Patients were retrospectively classified into steroid treatment and non-treatment groups.
- Caspase-3 expression was quantified and analyzed in relation to tissue type and clinical data.
Main Results:
- Significant caspase-3 protein expression was observed in the inflammatory component of adenoid tissues.
- No significant correlation was found between caspase-3 expression and the epithelial component of adenoid tissue.
- Demographic and clinical characteristics, including steroid use, did not significantly impact caspase-3 expression levels.
Conclusions:
- Caspase-3 is significantly expressed in inflammatory adenoid tissue.
- The study did not find an association between caspase-3 expression and the efficacy of nasal steroid administration in pediatric adenoid hypertrophy.
Objective:
Adenoid hypertrophy is a prevalent pediatric condition, often necessitating surgical intervention. Intranasal steroid administration shows promise as a conservative treatment, particularly by inducing apoptosis in adenoidal cells, leading to a reduction in adenoid size and inflammation. This study aims to characterize the expression profile of caspase-3 as an apoptotic inducer protein in inflammatory and epithelial adenoid tissues and explore its association with steroid administration.
Methods:
We performed immunohistochemical staining for caspase-3 proteins in adenoid tissues obtained from 51 pediatric patients aged between 2.5 and 12 years (mean age: 6.09 ± 2.1 years) who underwent adenoid surgery. A retrospective analysis of clinical data was conducted, categorizing participants into steroid treatment receivers (n = 25) and non-receivers (n = 26). Subsequently, the lymphoid inflammatory tissue and epithelial tissue from the adenoid were compared in terms of caspase-3 protein expression, and associated clinical variables were assessed.
Results:
Immunohistochemical analysis revealed significant caspase-3 expression in inflammatory tissues. The expression levels were scored, and no significant correlation was observed between inflammation and epithelium based on caspase-3 expression (correlation coefficient = 0.143; p > 0.05). Furthermore, demographic and clinical characteristics did not show a statistically significant difference in caspase-3 expression levels.
Conclusion:
Caspase-3 expression was significant in inflammatory adenoid tissue, but it showed no association with nasal steroid administration.
