摘要 目的了解慢性阻塞性肺疾病(COPD)患者肾素-血管紧张素醛固酮系统(RAAS)与继发红细胞增多间是否有关。方法检查34例有和无继发红细胞增多的COPD患者血浆中肾素(RA)活性、醛固酮(ALD)浓度和促红细胞生成素(促红素,EPO)水平。结果继发红细胞增多的COPD患者血中RA活性与醛固酮水平较无继发红细胞增多的COPD患者高近3倍,所有COPD患者RA活性与红细胞压积(PCV)呈正相关(r=0.45,P=0.02)而PaO2与红细胞压积呈负相关(r=-0.625,P=0.001)。经多元回归分析,RA活性及PaO2与红细胞压积显著相关。结论COPD患者继发红细胞增多可能与慢性乏氧导致RAAS的激活有关。
