红细胞分布宽度对住院特发性间质性肺炎患者预后的影响

目的探讨红细胞分布宽度(RDW)与特发性间质性肺炎(IIPs)预后的相关性。方法经诊断明确的IIPs患者61例,以死亡/生存作为观察终点对患者进行分组,记录两组患者的临床资料,分析liPs的危险因素,探讨RDW与IIPs预后的相关性。结果61例患者男33例,女28例,男女比例为1.2:1,平均年龄(64.60±16.33)岁,死亡组35例,生存组26例。与生存组相比,死亡组平均年龄更高(P=0.004)、出现呼吸衰竭更明显(P=0.002)。所有患者的RDW基线值为(15.12±1.71)%,RDW末次值为(16.30±2.54)%。死亡组RDW基线值和末次值分别为(15.95±1.50)%和...

Description
Summary:目的探讨红细胞分布宽度(RDW)与特发性间质性肺炎(IIPs)预后的相关性。方法经诊断明确的IIPs患者61例,以死亡/生存作为观察终点对患者进行分组,记录两组患者的临床资料,分析liPs的危险因素,探讨RDW与IIPs预后的相关性。结果61例患者男33例,女28例,男女比例为1.2:1,平均年龄(64.60±16.33)岁,死亡组35例,生存组26例。与生存组相比,死亡组平均年龄更高(P=0.004)、出现呼吸衰竭更明显(P=0.002)。所有患者的RDW基线值为(15.12±1.71)%,RDW末次值为(16.30±2.54)%。死亡组RDW基线值和末次值分别为(15.95±1.50)%和(17.84±2.26)%,均明显高于生存组(P=0.000)。Logistic多变量分析显示,在控制性别及年龄因素的基础上,RDW是liPs预后的独立预测因素。RDW判断IIPs预后的界值为15.70%,受试者工作特征曲线(ROC瞌线)下面积为0.94(95%C1:1.61~1.95),判断IIPs预后的敏感度为88.60%,特异度为96.20%;RDW≥15.70%组死亡率明显高于RDW〈15.70%组(P=0.000)。结论RDW与IIPs病变的严重程度独立相关,是IIPs预后的独立预测因素。

Objective To explore the correlation between red cell distribution width (RDW) and prognosis of idiopathic interstitial pneumonias (IIPs). Methods A total of 61 patients with confirmed diagnosis of IIPs were divided into the survival group and death group by using death/survival as end point of observation. Their clinical data were recorded. The risk factors of IIPs were analyzed and the correlation between RDW and prognosis of IIPs was explored. Results Among 61 patients, 33 were males and 28 were females, the ratio of male and female was 1.2 : 1, and the average age was 64.60 ± 16.33. Compared with the survival group ( n =26), the average age of death group ( n =35) was higher ( P =0. 004) and respiratory failure was severer (P=0. 002). The baseline value of RDW of all patients was ( 15.12 - 1.71) % and last value of RDW was (16.30 ±2.54) %. The baseline value and last value of RDW of the death group were (15.95 ± 1.50) % and (17.84
