[摘要] 目的 探讨特发性肺纤维化(IPF)患者血清透明质酸(HA)、层粘连蛋白(LN)的变化及意义。 方法 选择2014年6月~2016年6月在杭州师范大学附属医院呼吸科诊治的IPF患者38例为IPF组,选择同期健康非吸烟者30例为对照组。采用放射免疫法检测IPF患者及对照组血清HA、LN的水平;并与肺功能、6 min步行试验(6MWT)、呼吸困难评分等指标进行相关分析。 结果 与对照组比较,IPF组患者血清HA、LN水平显著升高(P < 0.05)。IPF患者血清HA、LN水平分别与用力肺活量(FVC)、第1秒用力呼气量(FEV1)、一氧化碳弥散量(DLCO)呈负相关(均r < 0,P < 0.05或P < 0.01);HA、LN水平与6MWT呈负相关(r = -0.637、-0.705,P < 0.01),与mMRC评分呈正相关(r = 0.618、0.552,P < 0.05)。 结论 血清HA、LN水平可作为评价IPF病情严重程度、判断疗效的指标,值得在临床推广应用。

[Abstract] Objective To explore the level and significance of serum hyaluronic acid (HA) and laminin (LN) in patients with idiopathic pulmonary fibrosis (IPF). Methods From June 2014 to June 2016 , in Department of Respiratory Diseases, Affiliated Hospital of Hangzhou Normal University, 38 patients with IPF were selected as control group, and 30 healthy persons without smoking at same time were selected as control group. The levels of serum HA and LN in IPF patients and cotrol group were detected by radioimmunoassay. And the correlation between serum HA, LN with lung function, 6-minute walk test (6MWT) and dyspnea score was evaluated. Results Compared with the control group, the levels of serum HA and LN of patients in IPF group were significantly higher (P < 0.05). The levels of serum HA and LN in patients with IPF were negatively correlated with FVC, FEV1 and DLCO (all r < 0, P < 0.05 or P < 0.01); HA and LN were negatively correlated with 6MWT (r = -0.637, -0.705, P < 0.01); the levels of serum HA and LN in IPF patients were positively correlated with mMRC score (r = 0.618, 0.552, P < 0.05). Conclusion These data suggest that serum HA and LN may be useful biomarkers to estimate the severity and treatment effect of patients with IPF.

特发性肺纤维化(IPF)是特发性间质性肺炎中最常见的类型[1]。IPF中位生存期约为3年,5年生存率仅20%~30%,预后很差[2-3],是弥漫性间质性肺病领域中最具挑战性的疾病。积极寻找早期诊断、评估病情变化及其严重程度、预测生存的生物标志物是IPF研究的重要内容。本研究通过检测IPF患者血清透明质酸(HA)、层粘连蛋白(LN)的变化,并与肺功能、6 min步行试验(6MWT)、呼吸困难评分等指标进行相关分析,探讨HA、LN的变化在IPF研究中的价值。
