Abstract
Aim: To evaluate various biomarkers of metabolism, immunity and inflammation in obstructive sleep apnea hypopnea syndrome (OSAHS). Materials & methods: After overnight polysomnography, blood was collected from 292 OSAHS patients or healthy volunteers. Serum content of inflammatory, immune, metabolic biomarkers were investigated. In addition, the effects of 1-month continuous positive airway pressure (CPAP) were studied in moderate/severe OSAHS. Results: C3, serum total complement activity, superoxide dismutase, uric acid were significantly higher in moderate/severe OSAHS than that in no/mild OSAHS. In contrast, IGF-1 in moderate/severe OSAHS was lower than it in no/mild OSAHS, which was negative correlated with apnea-hypopnea index. Moreover, CPAP significantly decreased C3, meanwhile elevated IGF-1. Conclusion: C3, serum total complement activity and superoxide dismutase were higher in moderate/severe OSAHS, while IGF-1 decreased. Elevated C3 and reduced IGF-1 in moderate/severe OSAHS may be reversed by CPAP.
