Serum S100A8/A9 Correlates to Surgery-Free Interval in Idiopathic Subglottic Stenosis.
Objective: Idiopathic subglottic stenosis (iSGS) is a progressive fibrotic condition of the subglottis that presents in women of northern European descent. Endoscopic dilation is a common surgical approach to management of iSGS. The surgery-free interval, or the time between endoscopic dilation procedures is considered an indicator of disease severity. Variations in surgery-free intervals among iSGS patients underscore the necessity for prognostic biomarkers. The objective of this study was to explore serum levels of the damage-associated molecular pattern S100A8/A9 as a prognostic biomarker in iSGS.
Methods: Serum from 20 iSGS patients and eight healthy controls was collected and S100A8/A9 levels were quantified using an ELISA. Patient data, including demographics and surgery-free intervals, were obtained from medical records. Serum S100A8/A9 levels were compared to surgery-free intervals. S100A8/A9 was also assessed using gene expression and immunofluorescence in iSGS specimens.
Results: S100A8/A9 was significantly elevated (p = 0.0413) in the serum of iSGS patients compared to controls (312.75 vs. 181.49 ng/mL). Linear regression analysis revealed a correlation (p = 0.009) between S100A8/A9 levels and endoscopic surgery-free interval. S100A8/A9 was significantly elevated (p = 0.0011) in patients with surgery-free intervals less than 1 year (455.2 ± 60.45 ng/mL; n = 8) compared to patients with intervals over 1 year (292.5.93 ± 162.4; n = 6).
Conclusion: S100A8/A9 is increased in the serum and tissue of patients with iSGS. In this cohort of iSGS patients, serum S100A8/A9 was associated with surgery-free intervals, potentially representing a prognostic biomarker. Further research within a larger cohort is needed to confirm these findings.
期刊介绍：
The Laryngoscope has been the leading source of information on advances in the diagnosis and treatment of head and neck disorders since 1890. The Laryngoscope is the first choice among otolaryngologists for publication of their important findings and techniques. Each monthly issue of The Laryngoscope features peer-reviewed medical, clinical, and research contributions in general otolaryngology, allergy/rhinology, otology/neurotology, laryngology/bronchoesophagology, head and neck surgery, sleep medicine, pediatric otolaryngology, facial plastics and reconstructive surgery, oncology, and communicative disorders. Contributions include papers and posters presented at the Annual and Section Meetings of the Triological Society, as well as independent papers, "How I Do It", "Triological Best Practice" articles, and contemporary reviews. Theses authored by the Triological Society’s new Fellows as well as papers presented at meetings of the American Laryngological Association are published in The Laryngoscope.
