摘要 目的探讨煤工尘肺伴慢性阻塞性肺疾病(COPD)患者早期肾功能损害变化及临床意义。方法采用免疫透射比浊法和速率法,测定煤工尘肺伴COPD和煤工尘肺伴COPD同时合并慢性呼吸衰竭患者,晨尿中视黄醇结合蛋白(RBP)、微量白蛋白(mAlb)含量和N-乙酰-β氨基葡萄糖苷酶(NAG)活力。结果煤工尘肺伴COPD时,3项肾功能早期损伤指标中,只有尿RBP(0.38±0.06 mg/L)水平与对照组(0.18±0.06 mg/L)比较,差异有统计学意义(P<0.01),而在煤工尘肺伴COPD同时合并慢性呼吸衰竭时,患者尿RBP(1.12±0.18 mg/L)、mAlb(47.5±10.52 mg/L)和NAG(28.00±8.51U/L)3项指标均明显升高,与对照组比较,差异均有统计学意义(P<0.01)。结论煤工尘肺伴COPD时,及时测定肾功能早期损伤的生化指标尿RBP、mAlb和NAG可早期发现肾功能损害。
