Abstract
PURPOSE: Inflammation plays a critical role in the pathogenesis of obstructive sleep apnea syndrome (OSAS). S100A12 is a newly identified inflammatory biomarker. This study aims to investigate whether serum S100A12 levels are associated with the presence and severity of OSAS in male patients. METHODS: A total of 126 male patients with OSAS and 74 controls were enrolled in this study. The presence and severity of OSAS was assessed by apnea-hypopnea index (AHI). Serum S100A12 levels were detected by enzyme-linked immunosorbent assay. RESULTS: Serum S100A12 levels were significantly higher in the OSAS group than in the control group (132.17 (range 101.86 to 174.49) ng/ml vs. 78.40 (range 58.35 to 129.44) ng/ml, P < 0.01). Multivariate logistic regression demonstrated that S100A12 was the only significant and independent predictor of OSAS (odds ratio 1.012, 95% confidence interval 1.006 to 1.017; P < 0.01). Serum S100A12 levels elevated with the increase in the severity of OSAS (S100A12 levels of 106.04 (range 83.92 to 135.13) ng/ml in mild OSAS group, 133.51 (range 109.64 to 208.95) ng/ml in moderate OSAS group, and 173.04 (range 131.88 to 275.77) ng/ml in severe OSAS group; P < 0.001). Serum S100A12 levels were independently correlated with AHI scores (r = 0.324, P < 0.001) CONCLUSIONS: Serum S100A12 levels were independently associated with the presence and severity of OSAS. These findings suggest that serum S100A12 level could be a potential biomarker for reflecting the presence and severity of OSAS.
