Resolvin is a checkpoint controller in inflammation. Matrix metalloproteinase-9 (MMP-9) is an airway remodeling regulator. We evaluated the levels of resolvin and MMP-9 protein in the serum and exhaled breath condensate (EBC) before and after continuous positive airway pressure (CPAP) treatment.
We enrolled 20 non-OSA snorers and 40 patients with moderate to severe OSA scheduled for CPAP treatment. ELISA was used to assess resolvin and MMP-9 levels in the serum and EBC. All patients underwent sleep assessment at baseline and 3 months after CPAP.
There was no between-group difference; moreover, there were no differences in the pre- and post-treatment serum levels of resolvin and MMP-9 in patients with OSA. Compared with non-OSA snorers, patients with OSA had lower resolvin and higher MMP-9 levels in the EBC. After CPAP treatment, the EBC levels of resolvin and MMP-9 in patients with OSA returned to normal.
Successful OSA treatment by CPAP can normalize EBC levels of resolvin and MMP-9.
消退素是炎症的一个检查点控制器。基质金属蛋白酶-9（MMP-9）是气道重塑的调节因子。我们评估了持续气道正压通气（CPAP）治疗前后血清和呼出气冷凝物（EBC）中消退素和 MMP-9 蛋白的水平。
我们纳入了 20 名非阻塞性睡眠呼吸暂停（OSA）打鼾者和 40 名中重度 OSA 患者，这些患者计划接受 CPAP 治疗。酶联免疫吸附试验（ELISA）用于评估血清和 EBC 中消退素和 MMP-9 的水平。所有患者在基线和 CPAP 治疗 3 个月后均进行睡眠评估。
组间无差异；此外，OSA 患者治疗前后血清中消退素和 MMP-9 水平无差异。与非 OSA 打鼾者相比，OSA 患者 EBC 中的消退素水平较低，MMP-9 水平较高。经 CPAP 治疗后，OSA 患者 EBC 中的消退素和 MMP-9 水平恢复正常。
CPAP 治疗 OSA 成功可使 EBC 中的消退素和 MMP-9 水平恢复正常。
